Quality Assurance  
Figure 1 and 2 show the most important stages of the QA  
system. Quality assurance (QA) departments, independent  
of production and development, are responsible for the  
selected measures, acceptance procedures and information  
feedback loops. Operating QA departments have state-of-  
the-art test and measuring equipment at their disposal, work  
according to approved methods of statistical quality control,  
and are provided with facilities for accelerated life and  
environmental tests used for both qualification and routine  
monitoring tests.  
1
Quality Assurance  
The high quality and reliability of integrated circuits from  
Siemens are the result of carefully managed design and  
production which is systematically checked and controlled at  
each stage.  
The procedures are subject to a quality assurance system;  
full details are given in the brochure “Quality Assurance  
lntegrated Circuits”.  
The latest methods and equipment for preparation and  
analysis are employed to achieve continuity of quality and  
reliability.

Conformance  
The general course of IC failure rate versus time is shown by  
a so-called “bathtub” curve.The failure rate has its peak  
during the first few operating hours (early failure period). After  
the early failure period has ended, the “constant” failure rate  
period starts during which the failures may occur at an  
approximately uniform rate. This period ends with a repeated  
rise of the curve during the wear-out failure period. For ICs,  
however, the latter period usually lies far beyond the service  
life specified for the individual equipment. Reliability tests for  
ICs are usually destructive examinations. They are,  
therefore, carried out with samples. Most failure mechanisms  
can be accelerated by means of higher temperatures. Due to  
the temperature dependence of the failure mechanisms, it is  
possible to simulate future operational behavior within a short  
time by applying high temperatures; this is called life test. The  
acceleration factor F for the life test can be obtained from  
Arrhenius’s equation  
Each integrated circuit is subjected to a final test at the end of  
the production process. These tests are carried out by  
computer-controlled, automatic test systems as hundreds of  
thousands of operating conditions as well as a large number  
of static and dynamic parameters have to be considered.  
Moreover, the test systems are extremely reliable and  
reproducible. The quality assurance department carries out a  
final check in the form of a lot-by-lot sampling inspection to  
additionally ensure the minimum percent defectives to  
ensure statistically that the PDA of released lots is less than  
the AQL agreed. Sampling inspection is performed in  
accordance with the inspection plans of DIN 40080, as well  
as of the identical MIL-STD-105 or IEC 410.

3.1 Measures taken during development  
The reliability of ICs is already considerably influenced at the  
development stage. Siemens has, therefore, fixed certain  
design standards for the development of circuits and layout,  
e.g. specifying minimum width and spacing of conductive  
layers on a chip, dimensions and electrical parameters of  
protective circuits for electrostatic charge, etc. An  
examination with the aid of carefully arranged programs  
operated on large-scale computers guarantees the  
immediate identification and elimination of unintentional  
violations of these design standards.  
where T2 is the temperature at which the life test is  
performed, T1 is the assumed operating temperature and  
k is Boltzmann’s constant.  
Important for factor F is the activation energy EA. It lies  
between 0.3 and 1.3 eV and differs considerably for  
individual failure mechanisms.  
For all Siemens ICs the reliability data from life tests is  
converted to an operating temperature of TA = 55 °C,  
assuming an average activation energy of 0.5 eV. The  
acceleration factor for life tests at 125 °C is thus 22,  
compared with operational behavior. This method considers  
also failure mechanisms with low activation energy, i.e. which  
are only slightly accelerated by the temperature effect.  
3.2 In-process control during production  
The manufacturing of integrated circuits comprises several  
hundred production steps. As each step is to be executed  
with utmost accuracy, the in-process control is of outstanding  
importance. Some processes require more than a hundred  
different test measurements. The tests have been arranged  
such that the individual process steps can be reproduced  
continuously.  
Various reliability tests are periodically performed with IC  
types that are representative of a certain production line this  
is described in the brochure “Quality Assurance Integrated  
Circuits”. Such tests are e.g. humidity test at 85 °C and 85 %  
relative humidity, pressure cooker test, as well as life tests up  
to 1000 hours and more. Test results are available in the form  
of summary reports.  
The decreasing failure rates reflect the never ending effort in  
this direction; in the course of the years they have been  
reduced considerably despite an immense increase in IC  
complexity.

• Direct I/Q modulation  
• Generation of orthogonal carriers with possibility of phase  
adjust with external resistors  
• 30-dB carrier rejection, 40-dB SSB rejection  
• 48-dB rejection of third order products with 500-mVpp  
I/Q-drive level  
• High output power with appropriate power matching  
network at 500-mVpp I/Q-drive level  
PMB 2240: – 3 dBm, PMB 2245: – 6 dBm  
PMB 2247: – 8 dBm  
• Integrated active part of RF oscillator  
• Possibility to use external RF-oscillator signal  
• The RF-oscillator signal is buffered for off-chip use,  
especially for receiver PMB 2405/07  
• Prescaler for the RF-oscillator signal  
• Possibility to use the IF oscillator integrated on the  
PMB 2405/07  
There is a prescaler by 64/65 for the RF-oscillator signal on  
chip, which can be used to implement the PMB 2307 PLL  
circuit.  
The on-chip FIX-PLL consists of the system clock divider, the  
IF-oscillator signal divider, the phase detector and the charge  
pump. The IF-oscillator signal divider is driven by the  
oscillator on the PMB 2405/07 or by an external discrete  
VCO. The IF-oscillator signal divider ratio of PMB 2240 and  
PMB 2245 is fixed. It can be selected either divided by 1 or by  
3 using PMB 2247 and PMB 2407 to drive the FIX-PLL with  
two IF frequencies (450 MHz or 150 MHz) to avoid spurious  
problems for PCS application.  
The two oscillator signals (IF and RF) are combined in the  
transmit mixer, and the image sideband and other mixing  
products are to be suppressed by an external interstage filter.  
The filtered signal reenters the chip at the modulator inputs.  
The modulator generates two orthogonal carriers which are  
mixed with the I- and Q modulation signals by two multipliers.  
The phase between the two carriers can be fine-adjusted to  
90° (orthogonality) by two external resistors for maximum  
SSB suppression. The outputs of the multipliers are added  
and amplified by a linear output stage.  
• Possibility to use external IF-oscillator signal  
• Fixed IF frequency PLL (FIX-PLL) for IF-VCO (PMB 2240,  
2245), switchable IF PLL working at 450-MHz or 150-MHz  
IF frequency (PMB 2247)  
• Supply voltage range 2.7 to 5.5 V  
• P-TQFP-48 package  
• Temperature range – 30 °C to 85 °C

• Wide IF range from 40 MHz to 300 MHz  
• Supply voltage range 2.7 to 4.5 V  
• P-TQFP-48 package  
The input signal is amplified by the internal LNA and filtered  
by an external filter. The filtered signal and the first local  
oscillator signal LO1 are mixed down to an intermediate  
frequency (IF). The amplification of the IF signal is performed  
by a digitally programmable gain-controlled amplifier.  
The second local oscillator signal LO2 is generated either by  
an on-chip oscillator or by an external VCO. The internal LO2  
signal is fed to a divider (PMB 2405-by 1; 2407-by 1 or 3) and  
then to a buffered output and also to a divider, which  
generates orthogonal signals at half the VCO frequency. The  
filtered IF signal re-enters the chip at the IF input, where it is  
amplified and converted to the final output frequency with  
each of the orthogonal signals. The resulting in-phase and in-  
quadrature signals pass through differential output drivers.  
• Temperature range – 30 °C to 85 °C  
Two differential operational amplifiers can be used as active  
baseband filters. At both outputs the differential offset is  
sensed via the sample and hold circuitry. A feedback loop  
corrects the remaining offset error below the tolerable input  
value of the GAIM PMB 2905 or any other baseband A/D  
converter.

RF-Building Blocks  
Introduction  
The era of the mobile communications has lead to an  
explosion in the variety of RF applications. Active for many  
years in this field with high performance IC solutions,  
Siemens RF ICs have found use in almost all wireless  
systems and are generally recognized for their high  
performance, functionality and cost-effectiveness.  
Building upon the success of the PMB 2200 modulator  
family, the PMB 2401 receiver and Siemens PLLs  
(TBB 200/TBB 206/PMB 2306), the new B6HF 25 GHz  
bipolar technology will allow for a further increase in  
performance, 3-V lower current consumption as well as for  
higher frequencies. Starting with the new prescalers  
PMB 2313/2314, all the standard RF-building blocks will be  
gradually moved to B6HF.

An external LO signal f0 is fed to the modulator input. This  
signal is first doubled and then bandpass filtered at 2f0. The  
filter may be realized by an external tank circuit. Alternatively,  
a local oscillator operating at 2f0 may be connected to the  
divider input. This signal is the clock for a 2:1 divider. At the  
output of the divider orthogonal carriers are provided which  
are mixed with the baseband modulation signals by two  
multipliers. The outputs of the multipliers are added and  
amplified by a linear output stage.

PMB 2306  
PMB 2307  
General Description  
Type  
Package  
The PMB 2306, PMB 2307 PLL are high speed CMOS ICs  
are especially designed for use in battery-powered radio  
equipment and mobile telephones. The intended application  
will be in GSM, PCN, DECT and other digital mobile systems.  
The wide range of dividing ratios also allows application in  
analog systems.

P-TSSOP-16-1 (Shrink, SMD)  
Adjustment to the “actual” value then takes place with the  
usual transient response as for small transfers in channel.  
The synchronous transmission ensures that no additional  
phase errors arise due to the change of reference  
frequencies.  
The circuit consists of a reference-, A- and N-counter, a  
dual-modulus-control logic, a phase detector with charge  
pump and a serial control logic. The setting of the operating  
mode and the selection of the counter ratios is done serially  
at the ports CLK, DA and EN.  
The PMB 2306/2307 has two standby modes (standby1, 2)  
to reduce the current consumption.  
The operating modes allow the selection of single or dual  
operation, asynchronous or synchronous data acquisition,  
4 different antibacklash-impulse times, 8 different PD-output  
current modes, polarity setting of the PD-output signal,  
adjustment of the trigger-edge of the MOD-output signal,  
2 standby modes and the control of the multifunction outputs  
MFO1 and MFO2.  
• Standby1 switches off the whole circuit, the current  
consumption is reduced to below 1 µA.  
• Standby2 switches off the counters, the charge pump and  
the outputs, only the preamplifiers stay active.  
The standby modes do not affect the port output signal. For  
the influence on the other output signals see standby table.  
The reference frequency is applied at the Rl input and scaled  
down by the R-counter. Its maximum value is 50 MHz. The  
VCO frequency is applied at the Fl input and scaled down by  
the N- or N/A-counter according to single or dual-mode  
operation. The maximum value at Fl is 220 MHz at single-,  
and 65 MHz at dual-mode operation.  
Features  
• Low operating current consumption  
• Low operating voltage  
PMB 2306: 3 V to 5.5 V  
PMB 2307: 2.7 V to 5.5 V  
The phase detector is frequency and phase sensitive. It  
produces a phase detector signal with adjustable anti-  
backlash impulses in order to prevent a dead zone at very  
small phase deviations. Phase differences smaller than  
100 ps can therefore be resolved.  
• High input sensitivity, high input frequencies (220 MHz)  
• Extremely fast phase detector without dead zone  
• Linearization of the phase detector output by current  
sources  
• Synchronous programming of the counters  
(N-, N/A-, R-counters) and system parameters  
• Fast modulus switchover for 65-MHz operation  
• Switchable modulus trigger edge  
• Large dividing ratios for small channel spacing  
– A-scaler 0 to 127  
– N-scaler 3 to 16380  
– R-scaler 3 to 65535  
• Serial control (3-wire bus: data, clock, enable) for fast  
programming (fmax 5 MHz)  
• Switchable polarity and rate of trimming rise of the phase  
detector  
• 2 multifunction outputs  
• Digital phase detector output signals (e.g. for external  
charge pump)  
frn, fyn outputs of the R- and N-scalers  
• Port 1 output (e.g. for standby of the prescaler)  
• External current setting for PD output  
• Lock detect output with gated antibacklash pulse (quasi  
digital lock detect)  
Programming of the IC is done by a serial data control. The  
contents of the messages are assigned to the functional units  
according to the destination address. Single or dual-mode  
operation as well as asynchronous or synchronous data  
acquisition is set by status 2 and should therefore precede  
the programming of the counters.  
The PMB 2306/PMB 2307 offer the possibility of  
synchronous data acquisition to avoid error signals at the  
phase detector due to non-corresponding dividing factors in  
the counters produced by asynchronous loading.  
Synchronous programming guarantees control during  
changes of frequency or channel. That means that the state  
of the phase detector or the phase difference is kept  
maintained, and in case of “lock in”, the control process starts  
with the phase difference “zero”.  
Synchronous transmission is particularly advantageous  
when large transfers in channel are to be made in a specific  
short transient recovery time. For this purpose a larger  
reference frequency is switched to in order to achieve rapid-  
“rough”-transient response, increasing the bandwidth of the  
loop at the time. When reaching the “quasi lock-in” state, the  
reference frequency is switched back to its original values.

Overview on ICs for Digital Terminals  
ISDN Voice Terminals  
The adaptation of existing data terminals (DTE) to an ISDN  
through a variety of interfaces (X.21, V24, RS232C, …) is a  
subject being covered by a number of emerging standards.  
With the digitization of the local loops, new ICs are needed to  
adapt the voice and data sources.  
The ITAC ISDN adapter circuit PSB 2110 brings a flexible  
solution to each configuration.  
Because of the analog/digital conversion is implemented in  
the telephone, Digital Signal Processing techniques (DSP)  
are suitably powerful tools for accomplishing this task. The  
ARCOFI® PSB 2160, ARCOFI®-BA PSB 2161 and  
ARCOFI®-SP PSB 2165 or PSB 2163 make the best use of  
this technology to deliver programmable, telephone specific  
codec/filter.  
A typical subscriber terminal configuration is shown in the  
figure 1.  
The modular concept allows the support of several interfaces  
like U (ISAC®-P), U (ISAC®-P TE, SmartLink-P), S  
P0  
PN

(ISAC®-S, ISAC®-S TE) and U (IEC-Q, IEC-T). All interface

ISDN Data Access  
The shown enhanced passive PC-card version (figure 3)  
includes the interface controllers and a DSP-based solution.  
There is a dedicated ROM-coded DSP-version for supporting  
modem (V.32), fax (V.29), data adaption (V.110, USART  
framing) and HDLC controlling in development. Please  
contact the Siemens sales office for details.  
Shorter dial-up times, higher data rates and simultaneous  
voice/data transmission comparing to analog transfer via  
modem make ISDN very interesting for data access.  
Especially ISDN data transfer via PC card is becoming more  
and more popular.  
Like the ISDN Voice Terminals (figure 1) both PC-card  
version are expendible for voice and active PC-card  
solutions.  
The signs below show 2 solutions of passive PC cards.  
The passive low cost version (figure 2) is optimal for  
point-to-point data transfer. The modular concept for this  
version includes the HDLC controllers and the interface  
controllers (optional for U -, U -, S -, U -interfaces

Subscriber Access Controller for UPN-Interface Terminals (SmartLink-P)  
PSB 2197  
General Description  
Type  
Package  
P-DSO-28-1 (SMD)  
The PSB 2197, SmartLink-P, implements the subscriber  
PSB 2197-T  
access functions for a digital terminal to be connected to a  
two-wire U interface.  
PN  
Features  
The PSB 2197 SmartLink-P is an optimized device for  
TE applications, covering the complete layer-1 and basic  
layer-2 functions for digital terminals.  
• Cost/performance-optimized U interface  
tranceiver, compatible to PEB 2096 OCTAT-P or  
PSB 2196 ISAC-P TE  
• HDLC controller with 2 × 4-byte FIFO per direction  
• IOM-2 interface for terminal application including bit  
clock and strobe signal  
• Uplink MUTE function  
• Selective B-channel loop back  
• Serial control port  
PN  
The PSB 2197 SmartLink-P combines the functions of the  
U
transceiver with reduced loop length (one channel of the  
PN  
OCTAT-P PEB 2096) and a simple HDLC controller for  
signaling data onto one chip.  
A pulse width modulator is included to provide an  
LCD-contrast control or a ring tone signal.  
• Pulse width output LCD-contrast control or ring tone  
generation  
• CPU clock and reset output  
• Watchdog timer  
• Test loops  
• Advanced CMOS technology  
• Low power consumption: active: 100 mW max.  
The serial control port of the SmartLink-P is compatible to  
most serial interfaces of microcontrollers. In addition it  
provides the microcontroller clock signal as well as an  
undervoltage detector and reset generation including a  
watchdog function.  
The Terminal Repeater function of the SmartLink-P allows to  
cascade two telephones which are controlled by one U  
PN  
interface from the line card or to extend the loop length by  
using an IEC-Q transceiver.  
The SmartLink-P can also be used as a simple HDLC  
controller which provides the TlC-bus access procedure. In  
this mode, the U transceiver is inactive.  
PN  
The PSB 2197 SmartLink-P interfaces to voice/data devices  
via the IOM-2 interface and provides an additional bit clock  
and strobe signal for standard codecs. The upstream  
B-channel information may be muted or loop back the  
downstream data.  
The PSB 2197 SmartLink-P is a 1-micron CMOS device  
offered in a P-DSO-28 package. It operates from a single 5-V  
supply.  
Note: U in the document refers to a version of the U  
PN  
P0  
standard with a reduced loop length.

General Exchange Architecture  
Analog Line Cards  
The conventional implementation is also characterized by  
the fixed adjustment of line interface conditions although  
telephone line conditions vary considerably with national  
standards and even with subscriber line installations. Under  
adverse conditions telecommunication equipment must  
match the subscriber line and termination impedances while  
suppressing return echoes in the two to-four-wire hybrid  
network. Compensating for line attenuation is just as critical  
for balancing the voice signals in the transmission and  
reception paths. To improve voice quality, subscriber line  
boards have to be matched to different line conditions by  
means of interchangeable discrete components. This  
approach is very costly regarding line board design and  
manufacturing. Furthermore, the reliability of a board filled  
with parts, wires and connections will decrease rapidly.  
In a digital exchange system the subscriber line boards  
provide the link between the subscriber and the switching  
network. The basic functions of analog line boards are  
known under acronym BORSHT (Battery, Overvoltage,  
Ringing, Supervision, Hybrid, Testing). Additional important  
tasks are voice frequency band limitation, analog to digital  
conversion into time discrete digital equivalents, time-slot  
assignment on the PCM highways and handling of  
signaling and control information.  
The conventional implementation uses two PCM ports  
and one µP interface per subscriber line leading to a large  
amount of wiring and, thus, problems are as crosstalk and  
large board size.  
The best solution to eliminate these line card trouble spots is  
the design of one standard line card, which can be  
customized for various line conditions and postal  
specifications through software control. The right choice of  
dedicate device allows the optimal line card design for each  
application in public switches, PBX systems as well as in all  
kinds of multiplexers and concentrators.

Optimized Line Board Architecture  
The Siemens Semiconductor concept is characterized by a  
centralized PCM interface controller device providing the  
variable Time-Slot Assignment (TSA), the communication  
with up to 64 subscriber line devices such as a signal  
processing codec/filter (SICOFI) or ISDN devices via the SLD  
(Subscriber Line Data) or IOM-2 (ISDN Oriented Modular)  
interface, and the interface with a microprocessor.  
The use of the signal processing codec/filter (SICOFI) avoids  
the analog network which has to be matched to different  
requirements by interchanging its discrete components.  
Based on Digital Signal Processing (DSP) methods the  
SICOFI allows the complete control of the line conditions by  
software.  
The all-over flexibility and programmability of the unique  
device concept gives the user the capability for designing a  
standard line card which can be optimized for each  
application and can be matched to various line conditions.  
As a characteristic architectural feature, for test, monitoring,  
and control purposes, the device permits efficient switching  
of data streams between all these interfaces and, therefore,  
ensures transparency between the PCM channels and  
control or signaling data. This opens up attractive  
possibilities such as common-channel signaling and  
microprocessor access to PCM data.  
The SLD/IOM-2 architecture leads to a highly modular line  
board configuration with low wiring, reduced board area, and,  
dependent on the SLIC being used, very few external  
discrete components.

Siemens ICs for Analog Subscriber Lines, Configurations and Interfaces

SLD/IOM®-2 Interface  
The SLD-bus is used by the PIC (PCM Interface Controller)  
to interface with the subscriber line devices. A Serial  
Interface Port (SlP) is used for the transfer of all digital voice  
and data, feature control and signaling information  
between the individual subscriber line devices, the PCM  
highways and the control backplane. The SLD approach  
provides a common interface for analog or digital per-line  
components. Through the PIC, which is the key device in  
the SLD-architecture, the PCM data is transparently  
switched onto the PCM highways. The PBC (Peripheral  
Board Controller) will make analog and digital subscriber line  
boards plug-compatible in a line equipment rack.  
Channel A and B are 64-kbit/s channels reserved for voice or  
data to be routed to and from the PCM highways. In an  
application where one SICOFI is connected to a SIP, voice is  
received on channel A and transmitted on channel A and B.  
For a three-party conference, channel B is the third-party  
voice channel. If two SlCOFls are connected to one SIP,  
channel A is assigned to one and channel B to the other  
SICOFI. Conferencing is not possible in this configuration.  
With digital subscriber line devices the two bytes can be used  
to carry 64-kbit/s data channels. The third and sixth byte  
locations are used to transmit and receive control information  
for programming the slave devices. The last byte in each  
direction is reserved for signaling data.  
There are three wires connecting each subscriber line device  
and the PIC: two common clock signals shared among all  
devices, and a unique bidirectional data link for each of the  
eight SIP lines. The Direction signal (DIR) is an 8-kHz clock  
output from the PIC (master) that serves as a frame sync to  
the subscriber line devices (slave) as well as a transfer  
indicator. The data are transferred at a 512-kHz rate, clocked  
by the Subscriber Clock (SCLK). When DIR is high (first half  
of the SLD 125 µs frame), four bytes of digital data are  
transmitted on the SLD-bus from the PIC to the slave (receive  
direction). During the second half of the frame when DIR is  
low, four bytes of data are transferred from the slave back to  
the PIC (transmit direction).

Frame Structure of the SLD Interface  
The lOM®-Revision-2 (IOM®-2) standard defines an industry  
standard serial bus for interconnecting telecommunication  
ICs. The standard covers line card, NT1, and terminal  
architectures for ISDN and analog loop applications.  
By providing data, control, and status information over a  
serial channel, the IOM-2 bus eliminates the need to have a  
microprocessor interface on the transceiver or codec. This  
reduces pin count and simplifies line-card layout, thus  
reducing cost.  
The line-card mode of IOM-2 provides a connection path  
between line transceivers (ISDN) and codecs (analog), and  
the line-card controller; the line card controller provides the  
connection to the switch backbone. The IOM-2 bus time  
multiplexes data, control, and status information for up to  
eight ISDN transceivers or up to 16 codec/filters over a single  
full-duplex interface.  
Information is multiplexed into frames, which are transmitted  
at an 8-kHz rate. The frames are subdivided into from one to  
eight subframes, with one subframe being dedicated to each  
transceiver or pair of codecs. The subframes provide  
channels for data, programming, and status information for a  
single transceiver or a codec pair.  
Siemens Aktiengesellschaft  
87  
SLD/IOM®-2 Interface  
The channel structure of the IOM-2 interface is as follows:  
• The fourth octet (control channel) contains  
– two bits for the 16-kbit/s D-channel  
– a four-bit command/indication channel, in ISDN  
applications or  
a six bit command/indication channel for analog  
subscriber applications  
– two bits MR and MX for supporting the monitor  
channel protocol.  
• The first two octets constitute the two 64-bit/s  
B-channels.  
• The third octet is the monitor channel. It is used for the  
exchange of data between devices using the IOM-2  
monitor channel protocol.

Extended Line Card Controller (ELIC®)  
PEB 20550  
General Description  
Type  
Package  
P-MQFP-80-1 (SMD)  
The Extended Line Card Controller (ELIC) PEB 20550-H is a  
device to allow the control, supervision and processing of  
voice, data and signaling information. It also provides access  
for the microcontroller to write/read data to/from the IOM and  
PCM interfaces and gives control over layer-1 devices.  
Revolutionary is the multiplexing concept allowing to use only  
one implemented HDLC controller to process the signaling  
information for up to 32 digital subscribers.  
PEB 20550-H  
The SACCO B is a second integrated HDLC controller  
behaving like an external device. It is mainly intended for  
signaling information between the line card and the group  
processor on the main board. This can be done either via a  
dedicated signaling highway or via the PCM highway. The  
SACCO B can also be used for music on hold, conferencing  
access and other features. The HDLC information handling  
between SACCO A and SACCO B always has to go via a  
microprocessor.  
The switching part of the ELIC controls space and times  
switching functions between subscriber line devices and time  
division multiplex highways. Furthermore it controls the flow  
of information between the subscriber interface ports and a  
processor.  
Features  
For processing signaling information two different HDLC  
controllers are implemented. The SACCO A is a Serial  
Access Communication Controller (HDLC) which allows  
extracting D-Channel information transported on the IOM  
interface. The data is then passed to the microcontroller. ln  
the downstream direction, the SACCO A passes data,  
packed in the HDLC protocol, from the microcontroller to the  
IOM interface.  
• Configurable interface (CFI) programmable for IOM-2,  
IOM-1, SLD or PCM  
• Switching between configurable interface (e.g. lOM-2) and  
PCM ports  
• Switching of 64 B-channels (32 digital or 64 analog  
subscribers) without blocking (128 × 128 matrix)  
• Two HDLC controllers with 64-byte FlFOs implemented  
• Arbiter logic to use one of the HDLC-controllers time  
multiplexed for a maximum of 32 digital subscribers  
• Full-duplex signaling protocols (LAPD or proprietary)  
• HDLC broadcast messages  
With 4 IOM interfaces, and 8 digital subscribers possible per  
interface, former designs needed 32 HDLC controllers (one  
for the D-channel of every subscriber). The SACCO A of the  
ELIC can serve all 32 channels in a time-multiplexing  
manner. This process is controlled by the BUS ARBITER.  
This part of the ELIC monitors all D-channels of the IOM  
interface and locks the SACCO A onto one D-channel as  
soon as the start of a HDLC frame is detected. After the end-  
flag of the HDLC frame has been received, the SACCO A is  
released again and can lock onto the next D-channel as soon  
as a new request is detected. During the assignment of the  
HDLC controller to a certain channel the other subscribers  
are not allowed to send information on their D-channels. To  
assure this a blocking mechanism is implemented which  
indicates to corresponding terminals that they may not use  
the D-channel. This mechanism works as well for the

• DMA interface  
wire ISDN capable interface for PBXs. Any ISDN Telephone  
can be connected to a PBX because the standard arbitration  
mechanism is used for blocking the phones.  
This concept saves the space and the costs of up to  
32 HDLC controllers. Due to the bursty characteristic of the  
signaling data, one HDLC controller is sufficient to process  
this data flow. For central office applications the ELIC is not  
recommended when the arbiter is used, as PTTs require  
transparent D-channels. In this case the SACCO A can be  
used as an independent HDLC controller.  
If the design needs higher D-channel data rates additional  
HDLC controllers (IDEC, PEB 2075) can be connected. This  
can either be done on the IOM interface and is than fixed for  
a certain subscriber or via the PCM interface which makes  
this extra HDLC controller flexibly assignable.

done with a 2nd order Sallen-Key Prefilter (PREFI). The A/D  
Converter (ADC) is a modified slope adaptive interpolative  
coder with a sampling rate of 128 kHz. Digital downsampling  
to 8 kHz is done by subsequent decimation filters D1 and D2  
together with the PCM bandpass filter (BP).  
Programmable digital filters for  
– impedance matching  
– transhybrid balancing  
– gain  
– frequency-response correction  
Configurable 3-pin serial interface  
– 512-kHz SLD-Bus (e.g. to PEB 2052/55)  
– burst mode with bit rates up to 8 MHz  
The digital input signal is received PCM encoded or linear,  
digitally filtered and D/A converted to generate the analog  
output signal. Digital interpolation up to 128 kHz is done by  
the PCM lowpass filter (LP) and the interpolation filters l1 and  
l2. The D/A Converter (DAC) output is fed to the 2nd order  
Sallen-Key Postfilter (POFI).  
• Programmable signaling interface with  
peripherals (e.g. SLIC)  
• High performance A/D and D/A conversion  
• Programmable analog gain  
• Advanced test capabilities  
– three digital loopback modes  
– two analog loopback modes

and AGX, digital gain adjustment GR and GX, frequency  
response adjustment R and X, impedance matching filter Z  
and the trans-hybrid balancing filter B.  
• No trimming or adjustment  
• No external components  
• Variable SICOFI master clock selection  
• Signaling expansion possible  
The SICOFI bridges the gap between analog and digital  
voice signal transmission in modern telecommunication

Signal Processing Codec Filter (SICOFI®-4)  
PEB 2465  
General Description  
Type  
Package  
P-MQFP-64-1 (SMD)  
The Signal Processing Codec Filter (PEB 2465-H), SICOFI-4  
is the interface between four analog subscribers and the  
digital switch. The chip combines all the circuitry needed for  
encoding, decoding and PCM filtering of 4 speech channels  
on CMOS chip. An integrated digital signal processor (DSP)  
allows the analog line card to be adapted to the widest variety  
of national specifications and applications by programming  
the individual digital filter functions. A wide variety of SLlCs  
(subscriber line interface circuits) can be employed and  
simply adapted.  
PEB 2465-H  
Features  
• Codec for four analog subscribers (public switch and  
PBX) usable towards the trunk and the subscriber  
• Specification according to relevant CCITT, EIA and  
LSSGR  
• IOM-2 interface  
• Usable with transformer and electronic SLlCs  
• DSP technology  
• Adaption to different country specifications with  
following programmable filters  
– AC impedance matching (return loss better than 30 dB)  
– transhybrid balancing (better than 30 dB)  
– frequency response  
– gain (steps of 0.05 dB)  
• Advanced test capabilities  
The SICOFI-4 can be used in both, PBXs and public  
switches. The external configuration does not vary – only  
decoupling capacitors are needed. Widely differing national  
specifications can be met with a single hardware by just  
changing the filter coefficients: Signal level, terminating  
impedance, equivalent impedance, frequency response  
correction and the required coding procedure (A- or µ-Law)  
are simple to program. Siemens provides well proven  
software for calculating the required coefficients.  
• DTMF generator  
• Level metering function  
• Boundary scan  
• Single 5-V power supply  
The SICOFI-4, together with standard SLlCs, also fulfills the  
new specification for idle channel noise in the out-of band  
range, already demanded by Japan and Great Britain.  
A flexible test concept operating at component level as well  
as at system level is provided to support users in designing  
and manufacturing their systems. The following test options  
are integrated into the SICOFI-4:  
Applications  
PBXs:  
• 4 analog lines for subscribers and trunks  
CO:  
• Interface for four analog subscribers  
• BIST (built-in self test) in the digital part  
• Boundary scan as per IEEE 1149.1  
• Functional testing with various test loops  
• Simple stimulation by two built-in DTMF (Dual Tone  
Multifrequency) tone generators  
• Function self test using what is known as the “level  
metering function” with which not only the chip but also the  
SLIC connected to it can be tested (system test).  
Interfaces  
• 4 × t/r interface  
• IOM-2 interface  
• Eight l/O signaling pins per channel  
• Boundary scan  
The powerful, modular IOM-2 interface implemented  
on the allows minimal wiring to be used on the board and  
thereby a low-cost design. A suitable controller (e.g. the  
ELIC, PEB 20550-H) is used to direct the relevant  
coefficients for filter programming and the required control  
signals as well as the voice signals to the SICOFI-4. Signals  
from the SLIC can be issued by the SICOFI-4 to the IOM-2  
interface and read out under interrupt control. This  
significantly reduces the load on the microcontroller.

The Signal Processing Subscriber Line Interface Codec Filter  
SLICOFI is a logic continuation of the well established family  
of the Siemens DSP Codec-Filter ICs with the vertical  
integration of all DC-feeding, supervision and PL meterpulse  
injection features on-chip as well. Fabricated in a standard  
1 µm BiCMOS technology the SLICOFI is tailored for very  
flexible solutions in digital communication systems. For the

PEB 3065 (SLICOFI®) Features  
• Single chip CODEC and FILTER including all LOW  
VOLTAGE SLIC functions  
• Only few external components required  
• No trimming or adjustments required  
• Specification according to relevant CCITT, LSSGR and  
DBP recommendations  
Based on an advanced digital filter concept, the PEB 3065  
provides excellent transmission performance. The new filter  
concept leads to a maximum of independence between the  
different filter blocks. Each filter block can be seen as a one  
to one representative of the corresponding network element.  
Together with the software package SLICOS, filter optimizing  
to different applications can be done in a clear and straight  
forward procedure. The AC frequency behaviour is mainly  
determined by the digital filters. Using the new oversampling  
1-bit Σ∆-AD/DA converter, linearity is only limited by second  
order parasitic effects.  
• Digital signal processing technique  
• Advanced low power 1 µm BiCMOS technology  
• PCM encoded digital voice transmission (A-Law or µ-Law)  
• Four pin serial IOM-2 interface

– two programmable tone generators  
• Optimized HV-SLIC interface  
The new – digital – solution of line feeding offers free  
programmability of feeding current and voltage as well as  
very fast settling of the DC operating point after transitions. A  
0.4-Hz lowpass filter in the DC loop is mainly responsible for  
the system stability.  
• Fully digital programmable DC characteristic  
– programmable constant current from 0 – 70 mA  
– programmable resistive values from 0 – 2 × 500 Ω  
• Programmable integrated Teletax injection and filtering

crossing injection  
Additionally telefax generation and filtering is implemented  
as well as free programmable (balanced) ring generation with  
zero crossing injection. Offhook detection with  
programmable thresholds is possible in all operating modes.  
To reduce overall power consumption of the line card, the  
SLICOFI provides a special mode called Power Denial where  
offhook is done via two high voltage inputs (VLINE) directly  
connected to the line since the HV-SLIC is switched off.  
– programmable frequency between 16.6 and 70 Hz  
– Programmable amplitude up to 2.125 Vrms (85 Vrms at  
a/b wire)

ISDN High Voltage Power Controller (IHPC)  
PEB 2026  
General Description  
Type  
Package  
The IHPC is an integrated power controller especially  
designed for feeding two-wire ISDN-transmission lines. One  
line can be powered by one IHPC. An external resistor  
defines the value of the current-limit for the line. Powering  
can be switched on or off by the logic inputs “PFEN” and  
“PFENQ”. With a logic low at the “APFI” output the IHPC  
signals that current-limiting is active; this signal is low-pass  
filtered. An external capacitor defines the corner frequency of  
this low-pass filter and the resulting delay time respectively. A  
second external capacitor is needed to make sure that  
longitudinal disturbance (AC) will not produce a current  
limiting effect. Line current-limiting and reducing this limiting  
level in case of overtemperature guards the IHPC against  
overloads.

including the address and control fields, are evaluated in the  
ICC. Depending on the status of the controller, positive or  
negative acknowledgements are generated without  
interrupting the CPU. When the procedure is terminated, an  
interrupt status is generated to inform the CPU of the status  
of the procedure. To enable the ICC device to be used in  
complex protocol applications with window size of up to 7, a  
transparent mode is implemented. In this mode the layer-2  
headers are transferred transparently to the CPU.  
• 2-µm CMOS technology and low power consumption:  
Standby: 2 mW  
Active:  
4 mW at 512 kHz  
The synchronization of the 16-kbit/s D-channel with the CPU-  
bus is performed by buffers with a capacity of 64 bytes per  
direction. Sophisticated buffer controllers allow overlapping  
input/output operation, which ensures that the maximum  
packet length is not limited by the buffer size.  
This feature greatly reduces the dynamic load of the  
microprocessor system.

PEB 2075  
General Description  
Type  
Package  
With the IOM-2 interface, designers have more flexibility with  
respect to handling of D-channel information. Layer-1  
transceivers are connected over the IOM-2 interface directly  
to either the PEB 2055 (EPIC-1) or the PEB 2054 (EPIC-S).

These devices are capable of switching not only the  
B-channels but also the D-channel. Thus, the designer can  
decide whether he wants to process D-channel signaling  
information decentralized, on the line card, or pass it through  
to be processed centrally.  
Features  
• Four independent HDLC channels  
• 64-byte FIFO buffering per channel and direction  
• Handling of basic HDLC functions  
• Single or quad connection to serial transmission lines  
• IOM- or PCM interfaces  
• Programmable time-slots and channel data rates (up to  
4 Mbit/s)  
• Collision detection and resolution circuitry for shared  
time-slots  
• 8-bit parallel µP interface with vector interrupt  
• Advanced low power CMOS technology: 50 mW  
The IDEC has been optimized for processing the D-channel  
signaling information on digital exchange line cards. Four  
independent HDLC controllers have been implemented on a  
single IC. Thus, one IDEC can handle the D-channels of up to  
four subscriber lines.  
The IDEC is based on the same core architecture as the  
PEB 2070 ICC, but has been optimized for exchange line  
cards and then repeated four times.

S-Bus Interface Circuit (SBC)  
General Description  
Type  
Package  
The four-wire S-interface between subscriber terminals and  
network termination has been standardized by CCITT  
recommendation I.430. Making use of a passive bus which  
provides separate receiver and transmit loops operating at  
192-kbit/s, up to eight terminals can be connected to the  
network termination. In case more than one terminal want to  
access the bus at the same time, a procedure is provided for  
resolving the collision problem. Since all layer-1 functions  
such as frame structure, data rate, power feeding,

Not for new development.  
For new development use the SBCX (PEB 2081)  
transceiver characteristics, activation/deactivation and  
subscriber access procedure are well defined, the S-bus can  
be considered an important tool for standardization of data  
communication equipment. It supports connections with a  
maximum length of 1 km in a point to-point and 150 m in a  
point-to-multipoint bus configuration.  
Features  
• S-bus transceiver according to CCITT I.430  
• Recovery of clock and frame signals in different modes of  
application.  
• Frame alignment for trunk module application  
• IOM interface compatible (IOM-1)  
• Handling of command/indication information during the  
activation/deactivation procedure  
• Switching of test loops  
• Control of bus access by echo-bit handling  
• Wake-up unit for activation from power-down state  
• Several operating modes including trunk applications with  
frame alignment  
• 2-µm CMOS technology and low power consumption:  
Standby: 4 mW  
The SBC is designed to meet all CClTT requirements, and,  
moreover, implements additional features necessary in  
specific applications. The device contains the transceiver  
function, timing recovery for the different modes of operation,  
circuitry for the collision resolution function and a state  
control block to handle the activation/deactivation  
procedures autonomously without the support of a  
microprocessor. A flexible buffer structure performs the  
frame-alignment function in PBX-trunk applications, where  
the system clock deviates from the central office clock  
derived from the line. Matching of the actual line attenuation  
is supported by receiver circuitry which contains adaptively  
adjustable thresholds.

ISDN Echo-Cancellation Circuit (IEC-T)  
PEB 20901  
PEB 20902  
General Description  
Type  
Package  
The most challenging requirement in ISDN is full-duplex  
transmission at a data rate of 144 kbit/s over the existing  
twisted-pair telephone cables (U-interface). Among several  
approaches for solving this problem, ping-pong time-  
compression multiplexing and echo cancellation have been  
proposed as most suitable for VLSI implementation.  
Moreover, echo cancellation has proven to be the best  
method for public lines which typically reach lengths in the  
range of 8 km.

After a careful study of different transmission codes, a 4B3T  
block code was chosen for the IEC-T which make use of  
ternary coding of the binary information. A particular  
Features  
• Full-duplex two-wire U-transceiver  
• 144-kbit/s user bit rate (2B+D)  
advantage of this code is its low frequency, DC-free  
performance spectrum with its energy peak at about 40 kHz.  
In this context, for a bit rate of 160 kbit/s the required baud  
rate is as low as 120 kHz. As a result transmission systems  
benefit from, low line attenuation low crosstalk distortion and  
high possible signal levels without causing EMI-problems.  
• 160-kbit/s total bit rate including maintenance and  
synchronization  
• Low transmission frequency of 120 kbaud by using the  
4B3T-ternary block code  
• Adaptive echo cancellation and equalization using digital  
filtering (DSP)  
• Recovery of clock and frame signals from the data stream  
• IOM-1 interface compatible  
The IEC-T is offered as a two chip solution consisting of:  
• Digital part, called PEB 20901  
• Analog part, called PEB 20902  
• Transmission range up to 8 km with 0.6-mm wires  
• Handling of command/indication information during

ISDN Burst Transceiver Circuit (IBC)  
PEB 2095  
General Description  
Type  
Package  
In addition to four-wire S-interface terminals, the IOM  
architecture also supports two-wire terminals for PBX  
applications. A survey of PBX-loop conditions demonstrates  
that typically 95% of the subscriber loops show line lengths  
below 2 km. Therefore, a more economical solution which is  
optimized to these shorter loop lengths is required.  
PEB 2095-N  
PEB 2095-P  
P-LCC-28-2 (SMD)  
P-DIP-24-1 (not for new designs)  
Features  
• Half-duplex burst-mode two-wire transceiver  
• 144-bit/s user bit rate (B+B+D)  
• 384-kHz line clock rate including maintenance and  
synchronization  
A time-compression multiplex concept has been chosen  
which – for separation of direction – divides the framing into  
a transmit and receive section. Taking synchronization bits  
and line conditions into account, a clock rate of 384 kbit/s,  
twice as high as for the S-bus, has been found to be optimal  
with respect to time compression, interference line  
attenuation and delay. The transceiver uses AMI coding,  
scrambling, automatic gain control and f-equalizing to  
obtain excellent transmission quality.  
• U interface, industry standard for  
P0  
2-wire PBXs (AMI-line code)  
• IOM-interface compatible (IOM-1 or IOM-2)  
• Adaptive line equalization (SC filter)  
• Recovery of clock and frame signals from data stream  
• Activation/deactivation procedure according to CClTT  
recommendation  
• Awake in power-down mode

From a system point of view, the lOM-compatible IBC is  
compatible with the IEC or SBC/SBCX as well as with the

Overview on Primary Rate Interface (PRI)  
Applications for the Primary Rate Interface include trunk lines  
between public central office (CO) exchanges, from a PBX  
to a CO, interlinking PBXs, the gateway connecting a LAN to  
the public network on a PBX, interlinking LANs, interfacing a  
large computer or data intensive terminal (e.g. CAD graphics)  
with the CO or a PBX etc.  
Frame alignment for all commonly used framing and  
multiframing formats is performed by the ACFA. The device  
synchronizes the transmit and receive signals, interfaces the  
data rate from the line to the 2.048 Mbit/s or 4.096 Mbit/s  
internal highway and codes/decodes one of three selectable  
line codes.  
Due to different technical evolutions in Europe and the US  
there are two basic interface types for 1st order transmission  
systems, the T1 and the CEPT or E1 standard. The ISDN-  
PRI is based on these two different standards. The main  
difference between ISDN-PRI and T1/CEPT transmission  
systems is the type of signaling used.  
For PCM24, this transmission code can be either B8ZS or  
AMI-ZCS whereas for PCM30, it is always HDB3. Alarms and  
error conditions are reported to the microprocessor via a  
maskable interrupt line. The ACFA can also be used for  
various signaling schemes. Rather than using the HSCC/  
HSCX, signaling information can be handled by a less  
intelligent communications controller without programmable  
time-slot access. For such devices, the ACFA provides the  
required signaling information via special purpose pins.  
Additionally, the ACFA has a DMA interface for transferring  
signaling information to/from a microprocessor controlled  
memory. Finally, signaling data can be accessed directly via  
the microprocessor interface.  
The T1 standard is based on the PCM24 technique, where  
twenty-four 64-kbit/s basic channels and one framing bit are  
combined into one 1.544-Mbit/s frame format.  
The CEPT standard is based on the PCM30 technique. The  
2.048-Mbit/s frame consists of thirty 64-kbit/s basic channels,  
one 64 kbit/s signaling channel and 64-kbit/s framing and  
maintenance channel.  
Siemens new generation of Primary Rate Interface  
component, the PEB 2254 FALC54 (Framing And Line  
Interface plus signaling Controller), implements the  
functionality of a line interface, frame aligner and signaling  
controller for both standards E1 and T1 on a single chip.  
Siemens Semiconductor Division offers a complete solution  
of ICs covering different standards and applications.  
The PEB 2236 IPAT®-2 (ISDN Primary Access Transceiver)  
and the PEB 2035 (Advanced CMOS Frame Aligner) fulfill  
the T1 and CEPT standards. At the system side the ACFA  
provides a synchronous PCM interface for connecting to  
other application specific ICs (e.g. MTSx, HSCX).  
Applications  
In general the following applications can be covered:  
• Synchronous/asynchronous multiplexers  
• Digital access cross connects  
• Central offices switches  
• Remote switches, subscribers loop carriers  
• LAN, MAN, WAN, Bridges, Routers  
• FITL  
The IPAT-2, together with the ACFA, implement the layer-1  
physical interface.  
Both devices are programmed via the µP interface to perform  
the different standards, applications and maintenance/  
service functions.  
The IPAT-2 is a monolithic line driver for primary access lines  
of either the PCM24 (T1, N. America/Japan) or PCM30  
(CEPT, W. Europe) standards. In the receive direction, the  
device recovers the clock and data signals from the line and  
forwards them to the ACFA.  
• PBX interfaces  
The following chapter outlines the application of the Primary  
Rate devices ACFA, FALC54 and I PAT-2 and shows the  
flexibility of the architecture.  
The IPAT-2 is transparent to the received line code. In the  
transmit direction, the device takes the signal received from  
the ACFA and forms it into transmission pulses according to  
CCITT recommendations for the PCM30 or AT&Ts DMI  
specifications for PCM24. Correspondingly, input/output jitter  
requirements comply with both CCITT and  
In the switching application the Primary Rate Interface is  
connected to a switching network of a PBX, CO or  
concentrator. The switching devices MTSL (Memory Time  
Switch Large), MTSC (Memory Time Switch CMOS) and  
MTSS (Memory Time Switch Small) perform the switching  
and data rate adaption. In addition to the switching function  
the MUSAC (Multipoint Switching and Conferencing) can  
handle 64-conference channels in any combination.

Overview on Switching, Attenuation and Conferencing IC-Family  
Supervision and control of the entire system, including  
connection set-up, maintenance and testing, is performed  
in a powerful central processing unit. Besides this, the  
through-switching of PCM channels is done in a switching  
network unit, whereas the tasks of a frame alignment unit are  
to interface PCM transmission routes with the switching  
system.  
In a digital switching matrix one distinguishes between two  
basic switching principles:  
• Time division multiplex  
• Space division multiplex  
A method that is frequently used involves a combination of  
the two principles, this being called space/time division  
multiplex. The figure illustrates the different principles.  
Digital exchanges put calls through by newly arranging the  
speech signals coded with 8-bit words (PCM time-slots). The  
code words are transmitted serially on PCM lines. The  
sampling frequency of 8 kHz produces PCM frames with a  
duration of 125 µs. The transmission rate on the line  
determines how many code words (speech channels) can be  
accommodated within a sampling period. With a data rate of  
2048 kbit/s for example, there are 32 time-slots of 8 bits each.  
Four lines with a data rate of 8192 kbit/s have a transmission  
capacity of 512 channels.  
In time division multiplex only the time-slot is altered during  
switching. All signals from a certain input PCM line are  
switched to a fixed output line, only the time-slot sequence  
may change.  
In space division multiplex incoming PCM data are only  
rearranged in space. The input time-slot equals the output  
time-slot. However, input from one PCM line can be switched  
to different output lines.

Wideband Switching  
or “Fractional” T1. 64 kbit/s time-slots are combined for  
An additional future requirement is wideband switching. In  
contrast to voice switching, wideband switching is  
optimized for data transmission, e.g. for ISDN H-channels  
higher data rates. As a precondition all switched time-slots  
have to be output in the same frame. For example  
6 time-slots could be combined to a 384-kbit/s bundle.

MTSC  
MTSL/MTSL-16  
Siemens Semiconductor offers devices which take into  
consideration the needs for efficient realization of these  
tasks. One of the switching network circuits offered is the  
Memory Time Switch in CMOS (MTSC) PEB 2045, which  
has the ability to connect any of 512 incoming PCM  
channels to any of 256 outgoing PCM channels on a single  
chip. A non-blocking switch for 512 time-slots can be built up  
with two devices only. A further expansion can be realized  
very easily too. Different kinds of operation modes enable the  
use of the MTSC PEB 2045 in 2048 Mbit/s, 4096 Mbit/s and  
8192 Mbit/s or mixed PCM systems.  
The largest in our family, the Memory Time Switch Large  
(MTSL) PEB 2047 is capable of switching up to 1024  
time-slots.  
The MTSL allows the switching of fractional T1 and data  
bundles. The MTSL-16 is a selection for 16-MHz  
applications.

P-LCC-44-1 (SMD)  
The PCM information for a complete frame is stored in the  
4-Kbit speech memory SM, i.e. all of the 512 words with 8 bits  
are written into a fixed position of the SM. This is controlled  
by the input counter every 125 µs. The words are read using  
random access with an address that is stored in a connection  
memory CM for each of the 256 output channels. The access  
to the CM is controlled by the output counter.

address must be written into the PEB 2045 via a µP interface.  
The SM-address contains the time-slots and line numbers of  
the incoming PCM words. The CM address consists of the  
time-slots and line numbers of the output words.  
The PEB 2045 can be connected to 2-Mbit/s, 4-Mbit/s and  
8-Mbit/s PCM systems, the device clock may be either  
4.096 MHz or 8.192 MHz.  
• Programmable clock shift with half clock  
step resolution for input and output in primary access  
configuration  
In a second operational mode the PEB 2045 together with the  
PEB 2035 (ACFA, Advanced CMOS Frame Aligner) and the  
PEB 2235 (IPAT, ISDN Primary Access Transceiver)  
implements the system interface of up to four primary  
multiplex access lines. This interface can be configured for  
2-Mbit/s, 4-Mbit/s and 8-Mbit/s systems; a clock shift for input  
and output lines with half clock step resolution is  
• Configurable for a 4096- and 8192-kHz device clock

General Description  
Type  
Package  
The MTSS PEB 2046 is a monolithic CMOS device which

The input information of a complete frame is stored in the  
speech memory SM. The incoming 256 channels  
of 8 bits each are written in sequence into fixed positions in  
the SM. This is controlled by the input counter in the timing  
control block with an 8-kHz repetition rate.  
Features  
• Time/space switch for 2.048-kbit/s PCM systems  
• Switching of up to 256 incoming PCM channels to up to  
256 outgoing PCM channels  
• Eight input and eight output PCM lines  
• Configurable for a 4096- and 8192-kHz device clock  
• Tristate function for further expansion and tandem  
operation  
• 8-bit µP-interface  
• Single +5-V power supply  
• Advanced low power CMOS technology  
For output, the connection memory (CM) is read in sequence.  
Each location in CM points to a location in the speech  
memory. The byte in this speech memory location is read into  
the current output time-slot. The read access of the CM is  
controlled by the output counter which also resides in the  
timing control block.  
Thus the CM needs to be programmed beforehand for the  
desired connection. The CM address corresponds to one  
particular output time-slot and line number. The contents of  
this CM-address point to a particular input time-slot and line  
number (now resident in the SM).

Memory Time Switch Large (MTSL)  
PEB 2047  
General Description  
microprocessor command. As a result the input countervalue  
on the rising edge of the FS signal can be read from an  
internal register. Thus delay compensation is easily  
managed by programming appropriate clock shift values  
and/or a possible software offset.  
The MTSL PEB 2047 is a memory time switch device.  
Operating with a device clock of 4096 kHz or 8192 kHz it can  
connect any of 1024 PCM-input channels to any of 512  
output channels.  
During operation of the chip, a frame length check, which  
controls correct synchronization by the SP pulse and  
generates an interrupt in case of lost or achieved  
synchronization is also supplied.  
The input information of a complete frame is stored  
in the on-chip 8-kbit data memory DM. The incoming  
1024 channels of 8 bits each are written in sequence into  
fixed positions in the DM. This is controlled by the input  
counter in the timing control block with an 8-kHz repetition  
rate.  
The standard 8-bit µP interface can communicate with Intel  
multiplexed/demultiplexed microprocessors as well as with  
Motorola demultiplexed processors. It gives access to the  
internal registers and to the control – and data memory. Five  
directly addressable registers are provided. All other  
registers and the memories are accessed by a simple three  
byte indirect access method (similar to the MTSC PEB 2045).  
For outputting, the connection memory (CM) is read in  
sequence. Each location in CM points to a location in the data  
memory. The byte in this data memory location is transferred  
into the current output time-slot. The read access of the CM  
is controlled by an output counter.  
The switching path of the MTSL including input buffer, data  
memory, control memory, output buffer and timing control  
can be tested in the system by a built-in selftest. After  
activating this mechanism it takes 1.25 ms (8192 kHz) until  
the result “selftest ok/selftest not ok” can be read from the  
internal status register.  
The synchronization of this procedure will be achieved by a  
rising edge of the synchronizing pulse SP, which is always  
sampled with the falling edge of the device clock.  
Different modes of operation are configurable at the PCM-  
input interface. Also, 8 PCM-input lines can be synchronized  
with individual clock shift values to compensate different line  
delays. If more than 8 inputs are used one clock shift value  
controls up to two ports at the same time.  
After test completion the control-memory is also reset.  
In applications where 64-kbit/s channels are combined for  
higher data rates (e.g. ISDN H-channels) the MTSL ensures  
that all switched time-slots are output in the same frame.  
The input lines IN8 to IN15 can be used as additional  
frame-synchronization inputs FS. After synchronizing the  
device by the SP pulse, the FS inputs can be evaluated on a  
per port basis. This evaluation procedure is started by a  
In voice applications where a low delay is important, the  
MTSL can be programmed for minimized switching delays.

A World of Applications  
Data communication has gained a key role in modern  
computer systems. We are on the threshold of an era of total  
communication: every (micro)computer unit has to be able to  
communicate with other devices – either in synchronous or  
asynchronous data transmission mode.  
Office Automation and  
Wide Area Networks (WAN)  
Typical ESCC2 (Enhanced Serial Communication Controller  
with 2 channels, SAB 82532) applications are  
communication boards for workstations and minicomputers  
as well as l/O multiplexers, bridges and gateways (X.24,  
PRI). ESCC2 can be used for nearly all applications from  
terminal adaptors and fast HDLC links to Primary Rate  
Interfaces (T1/S2) or ISDN interfaces (SO); using unique  
software.  
Let us have a look at this rapidly growing world of many  
different applications. There are among others the following  
applications: telecom, office automation, traffic control,  
medical equipment, and factory automation.  
Telecom  
If the designer requires multichannel access, he can save a  
tremendous amount of board space by using the highly  
integrated eight-channel multiprotocol controller SAB 82538  
(ESCC8): four ESCC2s (eight serial channels) in one  
package.  
Todays telephone and telecommunication equipment is  
getting more and more digitalized while the older analog units  
are being replaced. This means that analog signals are  
converted to digital data as soon as possible before being  
transferred and processed. Back-conversion is made as late  
as possible. Consequently the amount of transferred data in  
telecom applications is increasing tremendously. Depending  
on the desired data throughput and transmission mode, the  
designer always gets the right choice with serial  
communication ICs from Siemens. There are a lot of goals to  
be met: transfer control by high level transportation protocols,  
transmitting and receiving data pockets, time-division  
multiplexing in time-slot systems, handling of different data  
encoding/decoding schemes, etc.  
Fast LANs  
If clock recovery up to 4 Mbit/s is needed (e.g. in fiberoptic  
transmission systems), the designer can use ESCC2  
(Enhanced Serial Communications Controller, SAB 82532).  
Basically, the ESCC2 is a faster 16-bit HSCX with a big  
bundle of extra functions. HDLC-data transfer can be  
implemented up to 10 Mbit/s. ESCC2 is a multiprotocol  
controller which enables designers to use synchronous,  
bisynchronous as well as asynchronous, fast data transfer  
with one chip on one software basis.  
All these kinds of data transfer can be managed by  
SAB 82525 or SAB 82526. These ICs are called High-Level  
Serial Communication Controllers Extended (HSCX,  
SAB 82525) and Single-Channel High-Level Serial  
Communication Controllers Extended (HSCX1, SAB 82526).  
They were especially designed for serial communication  
interfaces in telecom networks requiring HDLC based  
protocols.  
Typical HSCX applications are network communication  
boards, central D-channel signaling, DMI boards, data-link  
controllers in digital mobile radio networks as well as cordless  
telephone sets.

Siemens’ family of serial communication controllers  
ESCC2  
comprises a full range of different ICs. While each of them is  
designed to enhanced particular features, together they  
compose a wide profile of performance. Thus, most likely our  
family of complementary devices offers an ideal solution to  
many applications in serial data communications.  
The Enhanced Serial Communications Controller (ESCC2) is  
a multiprotocol controller offering an extraordinary profile of  
protocol options at a high-speed transfer rate of up to  
10 Mbit/s for each of its two independent channels.  
ESCC2 was developed for the different communication  
requirements of wide area network, local area network, small  
area network and proprietary network applications.  
HSCX  
The High-Level Serial Communications Controller Extended  
(HSCX) supports a number of synchronous standardized  
protocols and a greater number of proprietary protocols at a  
transfer rate of up to 4 Mbit/s. Each of its two channels works  
independent of the other. Its specific fields of application are  
proprietary HDLC local area networks (LAN).  
The result is a communications controller as a standard for  
implementing Open System Interconnection (OSI) layers-1  
and -2 in all these applications. This fact noticeably reduces  
development and system costs.  
The board space, for example, is reduced by on-chip collision  
detection and resolution, programmable preamble, clock  
recovery, the logic for multiple protocols and multiple  
encodings, 16- and 32-bit CRC, time-slot, assignment,  
queued interrupt status for all important events like receiver  
FIFO full, receiver FIFO overrun and end of frame  
transmission.  
HSCX 1  
The Single-Channel High-Level Serial Communications  
Controller Extended (HSCX1) is the single channel version of  
HSCX.

The reduction of the software size, due to the 16-bit Intel or  
Motorola processor interface, the direct register accessibility,  
large FlFOs, vectorized interrupts and four channel DMA  
support lead to higher performance and decrease CPU time  
to an absolute minimum.  
32 data channels of a full-duplex PCM highway. It has been  
designed for use in fractional T1 interfaces as well as for  
applications in switching systems.  
ADMA  
Less system cost, less development cost, less board  
space, less power consumption and high performance in a  
proven 1-µm CMOS technology are what you gain by using  
this communication genius as a standard for all your  
applications.  
The Advanced DMA Controller (ADMA) is a four channel l/O  
coprocessor that is optimized to handle data transfers in  
either 8-, 16- or 32-bit microprocessor systems. It can  
transfer up to 40 Mbytes of data per second in a 20-MHz  
system. The ADMA transfers data using single cycle, two  
cycle and 32-bit fly by operations and can gather or scatter  
data with efficient linked list data chaining, making it one of  
the most versatile DMA controllers available today. A smaller,  
reduced cost version of the ADMA (SAB 82C257) is also  
available.  
The following ICs are in development or under definition and  
will be available in due time to offer new attractive solutions  
for serial communication control.  
ESCC8  
The eight-channel Enhanced Serial Communications  
Controller (ESCC8) offers eight independent serial channels.  
Basically it consists of four ESCC2 cores. It is a very suitable  
solution for multiprotocol and multichannel applications.  
ASCC8  
The ASCC8 is an eight-channel Universal Asynchronous  
Receiver/Transmitter (UART). It is optimized to handle eight  
high-speed asynchronous channels at rates of up to 2 Mbit/s  
in 16-×-oversampling mode. The ASCC8 is ideally suited for  
applications that include card-to-card signaling MODEM  
pools, asynchronous routers, and simple high speed  
point-to-point communications between processing elements  
within a large system.

Asynchronous Transfer Mode (ATM) ICs  
Introduction  
Traditional telecommunication structures are based on Time  
Division Multiplexing (TDM), offering fixed-bandwidth time-  
slots. ATM however sends data only when required, i.e.  
frames are sent asynchronously. By packing the information  
in 53-byte cells, including a 5-byte header containing the  
destination address, data is guided through the network  
along virtual paths and channels. ATM offers bandwidth on  
demand with highspeed transmission ranging from kilobytes  
up to gigabytes per second.  
In the last few years, Asynchronous Transfer Mode (ATM)  
has made big leaps towards standardization and  
practicability.  
Acceptance in the market is high, due to the future need of  
highspeed networking and seamless internetworking. This  
new technology perfectly suits these market demands. ATM  
networks offer bandwidth on demand, thus being capable of  
matching the user’s data needs from sporadic high-  
bandwidth bursts to isochronous constant-bandwidth. ATM  
technology offers high-speed networks with various  
bandwidths and works with any type of transmission  
infrastructure. The very flexible basic structure allows to build  
and interconnect high-speed WANs, corporate WANs/MANs,  
backbone LANs, or powerful links to desktop terminals.  
Siemens Semiconductor Group addresses the market’s  
demand for this kind of network technology by being a driving  
force in the standardization activities and providing a  
complete ATM chipset to the market. ATM-system designers  
are supported by a family of Siemens ATM devices to build all  
kind of ATM applications. This ranges from dedicated ICs for  
Network or Line Interface Cards to powerful ATM switches  
and transmission devices.

Asynchronous Transfer Mode (ATM) ICs  
Building Seamless ATM Networks  
ATM technology is capable of providing powerful networks  
for various needs. Such an application could be a large  
campus network, just as shown in the figure below. In this  
example, several backbone switches, located at different  
places, are linked together. However, ATM allows this  
network to be managed centrally, since all backbone  
switches are configured to logically constitute one single  
switch. Workgroups are connected to the backbone via ATM  
workgroup switches.  
The functionality of the Siemens ATM chipset, such as the  
cross connect feature of the ATM-Switching Matrix  
PXB 4310, allows members of the same workgroups to  
communicate effectively with each other without occupying  
the backbone. Only two devices of the Siemens ATM chipset  
are required to develop ATM-Network Interface Cards for  
PCs and WS, providing seamless access to the network.

ATM-Application Examples  
ATM-Workgroup Switch  
Instead of using a hub to connect a small number of  
computers (workgroup), an ATM-work group switch can be  
applied. Data transmission to the computers is handled by  
transceiver devices, such as the PXB 4230 for unshielded  
twisted pair lines, or PXB 4240 for SDH/SONET lines. The  
actual switching function is performed by the ATM-Switching  
Matrix (ASM) PXB 4310.  
This cell switch features 32 inputs and 16 outputs with cross  
connect functionality. The ASM chip is designed to a special  
cell format, in order to reduce the pin count and power  
dissipation. Up-stream and down-stream conversion from the  
standard 53-byte ATM-cell format to this Siemens proprietary  
format SLIF (Switch Link Interface) is performed by the ASP  
chipset PXB 43201 and PXB 43202.

dissipation, the inputs and outputs are realized as serial,  
differential transmission lines. This Siemens proprietary  
interface is defined as SLIF (Switch Link Interface) and its  
electrical characteristics are according to the LVDS standard.  
Internally the ASM works with 64-byte ATM cells, each cell  
containing the 53-byte ATM cell extended by routing and  
housekeeping information. Conversion from 53-byte cell  
format to SLIF format is done by the Siemens ASP (ATM -  
Switching Preprocessor) chipset PXB 43201/2.

programmable digital filters adapt the transmission behaviour  
especially for AC impedance matching transhybrid balancing  
frequency response and gain.  
The tools consist of either component evaluation boards or  
sometimes even almost ready to copy system designs. Also  
software chip drivers are often supplied to ease the  
integration of components into a customer’s software design.  
In some cases software skeleton solutions or even ready to  
use software is supplied to speed up the whole system  
design.  
For analog line card designs in digital communication  
systems a family of Siemens Codec-Filter ICs can be  
offered:  
Besides the tools supplied by the silicon vendor a lot of third  
party tools are available on the market which can efficiently  
be used. The support tools supplied by Siemens are typically  
designed to be used in conjunction with a PC and third party  
software tools giving a very powerful environment.

As shown in the table above the best application for our  
codec filter ICs may be in a Private Branch Exchange (PBX)  
and/or in a Central Office (CO). The SICOFI, SICOFI-2 and  
SICOFI-4 Codec-Filter ICs may also be used in TRUNK  
applications.  
The four channel codec filters PEB 2465 and PEB 2466 are  
the logic continuation of a well established family of Siemens  
Codec-Filter ICs.  
The SLICOFI PEB 3065 is a single codec and filter with an  
optimized high voltage. SLIC interface including all low  
voltage SLIC functions. The DC-characteristic is fully digitally  
programmable. Together with the HV-SLIC circuitry  
PEB 4065, Siemens offers a complete system solution for  
central office applications.  
Based on an advanced digital filter concept the PEB 2465 as  
well as the PEB 3065 provide excellent transmission  
performance and high flexibility. They fulfill all specifications  
to relevant CCITT, EIA and LSSGR recommendations. The  
new filter concept (second generation) leads to a maximum  
of independence between the different filter blocks.

Tools for ISDN Basis Rate Line Card Designs  
U Transceiver Development Tool (2B1Q)  
The IEC-Q Reference Board interfaces ISDN transmission  
lines and terminal areas providing echo cancellation and  
message recovery using digital techniques. Hence the main  
use of the IEC-Q Reference Board is to accomplish  
performance measurements i.e. bit error rate (BER)  
measurements on the ETSI and ANSI defined loops.  
2.1  
Together with the SIPB 5121 Line Card Module the IEC-Q  
Reference Board SIPB 2091 constitutes the layer-1  
functionally needed for the evaluation of various digital line  
card architectures using 2B1Q technique for interfacing with  
the U-reference point.  
The optimized layout of the Reference Board allows for  
performance measurements in all operation modes available  
with the IEC-Q. The so called hybrid was developed to reach  
optimum loop lengths and to cover all 15 ANSI loops as well  
as the 8 ETSI defined loops. The figure below shows a typical  
configuration with LT and NT 1 where the interconnection  
between the two U-transceiver devices is established with  
means of a dual lead copper wire (U).  
2.2  
Introduction to the IEC-Q Reference Board  
SIPB 2091, SIPB 2092 and SIPB 2092-H  
The IEC-Q Reference Board was developed to demonstrate  
the performance of the Siemens IEC-Q (PEB 2091)  
U-interface transceiver IC. The IEC-Q (ISDN Echo  
Cancellation Circuit) uses 2B1Q code for transmission on U.  
A single board can be configured by the user to suit multiple  
operation modes such as LT and NT modes. Test points  
allow for comfortable monitoring of relevant signals. This  
enables the developer to quickly comprehend both the  
IC- and U-interface-related signals.  
The SIPB 2092 additionally supports the stand-alone  
(IOM-2) mode and the µP-interface mode. SIPB 2092-H is  
identical to SIPB 2092 except that a P-TQFP-64 package  
socket instead of a P-LCC-44 socket is provided. For stand-  
alone operation of the IEC-Q, both SIPB 2091 and SIPB 2092  
are equally suited.

Bit-Error-Rate Measurement  
with SIPB 5000 Main Board  
The configuration below describes the use of standard LT/NT  
applications for the purpose of BER measurements when  
supplemented with two BEAM modules. The figure shows  
the complete SIPB system set-up for a BER measurement in  
LT-NT direction.  
For bit-error-rate (BER) measurements on U the following  
add-on modules are required on the LT side in addition to the  
LT IEC-Q Reference Board:  
ISDN Terminal Adaptor Module (ITAC ) SIPB 5140  
LAYER-2 Module SIPB 5120-2  
Comments:  
For the bit-error-rate measurement the LT is configured in the  
LT-512-kHz mode since the BEAM module only supports a  
512-kHz-DCL clock rate.  
Bit Error Adaptor Module (BEAM) SIPB 5312  
The following modules are required for BER measurement  
on the NT side in addition to the NT IEC-Q Reference Board:  
With means of the two BEAM modules the BER test  
equipment can be synchronized to the IOM clock rate as well  
as insert and extract B1/B2 channel data via IOM. BER  
measurement is then accomplished by comparing the  
inserted with the extracted data. A line simulator is used for  
emulating lines and loops including NEXT noise impairments  
in order to run performance tests according to the relevant  
specifications (ETSI/ANSI).

The Different Steps in Development  
Designing the Hardware  
The ISDN Telephone Development Board SIPB 8051 is a  
more or less ready to copy environment to demonstrate the  
terminal system in silicon using the ARCOFI-SP (PSB 2163),  
the ISAC-S TE (PSB 2186) and the one-chip controller  
SAB 80515 with the ISDN protocol software. An ITAC  
(PSB 2110) for the rate adaption as well as an ISAC-P TE  
3.2.1  
The SIPB 5000 system can be used as a platform for all  
development steps. In a later stage it is of course necessary  
to make a cost optimized design. For this a subset of the  
board design can be used. All the wiring diagrams are  
shipped with the board to speed up this process.  
(PSB 2196) for the U interface is also onboard.  
PN  
To set up a development environment for serious  
developments it is best to use both an SlPB 7011A kit as a  
network terminator being able to simulate the public ISDN  
and secondly an SIPB 8051 system as the real development  
platform. Both systems should be connected and of course a  
PC should be connected to the SIPB 8051 to run a  
C-Compiler and to download and debug code.  
3.2.2  
Developing the Software  
In a premature stage of a development it is very useful to  
verify the design by running program sequences on a similar  
hardware platform. To manage this task Siemens offers a  
very comfortable menu-driven testing and debugging  
software. The package delivered with the userboard allows a  
direct access to the chip registers by symbolic names.  
Subsequent accesses may be written to a file and run as a  
trackfile.  
The Keil C51 professional package (in USA Franklin C51  
package) as well as the development package of the  
Swedish company lAR Systems (in USA Archimedes) have  
been used with the SIPB 8051. Their high level language  
debuggers can be used very efficiently with the SlPB 8051.  
Example trackfiles for different configurations are delivered in  
the package and will be a great help to the user in getting  
started and to speed up his software development.  
Both systems should be connected and an 8051 type  
C-Compiler and high level language debugger should be  
available. Additionally the IOS software should be used as a  
very efficient software platform if a public protocol is required.  
This software is a very compact software solution. It fits on a  
one chip controller without needing additional memory. For  
rapid prototyping or PTT approval an E2PROM version of the  
80C515A is also available.

the chips but it can also be used to run real software (see

The Different Steps in Development  
Designing the Hardware  
4.2.3  
Figuring out the ARCOFI -SP Coefficients  
for Speakerphone  
4.2.1  
Siemens Semiconductor Group offers two dedicated,  
DSP-based speakerphone realizations ARCOFI-SP  
PSB 2165 and PSB 2163.  
The SIPB 8051 can be used as a platform for all development  
steps. In a later stage it is of course necessary to do a cost  
optimized design. For this a subset of the SIPB 8051 design  
can be used. All the wiring diagrams are shipped with the  
board to speed this process up.  
The first digital speakerphone support was implemented in  
the ARCOFI-SP PSB 2165, which already exists since 1991.  
A substantial feature of the ARCOFl-SP is to provide means  
for minimizing feedback in electrical loops and to  
compensate for acoustical couplings. Therefore ARCOFI-SP  
offers 23 parameters which are set by software  
4.2.2  
Developing the Protocol Software  
A major task in the design work is the development of the  
public ISDN protocol software. To ease this work Siemens  
provides the IOS as an almost ready to copy protocol  
software kernel. IOS has been designed in C and it can be  
ported in nearly all CPU environments. For the development  
of ISDN phones or TAs IOS has been ported onto an  
80C515. Still it might be necessary to do some modifications  
or more likely add some features. The board can immediately  
load code but the use of a high level debugger like the Keil  
(FRANKLIN) TS51 or the IAR (ARCHIMEDES) C-SPY is  
recommended. After loading the target system Monitor down  
to the board the debuggers work perfectly. An emulator is  
really not required.  
programming. No further external components or trimming  
are required. This half-duplex mode is based on a two point  
speech detection, which controls the mode switching within  
125 µs.  
The speakerphone support of the new ARCOFI-SP  
PSB 2163 is based on a “Stronger-Wins” algorithm. Two  
speech comparators, one at the acoustic (AE) and one at the  
line side (LE), mainly control the switching from one active  
mode to another one. They compare permanently the signal  
levels of both signal paths and control the influences caused  
by the echoes at the acoustic side and at the line side. Once,  
a speech detector has detected speech activity, the  
comparator switches immediately to the direction where the  
speech signal is louder than the other one plus the returned  
echo.  
This offers the advantage of a completely separate  
programming of the sensitivity and of the echo control. The  
sensitivity is adjusted by the speech detectors and the  
speech comparators control the different feedback paths at  
the acoustic side and at the line side.

an optimum design of the telephone case.

GOLDplus Evaluation System  
The Siemens GOLDplus evaluation system comprises all  
parts of a GSM full rate and half rate handset. It consists  
mainly of the GOLDplusX GSM baseband board and the  
GOLDplus GSM RF board as shown in figure 1.  
For both ARCOFI-SPs there is very comfortable coefficient  
software called ARCOS-SP PLUS which eases and reduces  
any optimizations to just a simple task at the PC.  
Thanks to the DSP realization, the main operational functions  
are all parameterized. This technique offers a high level of  
flexibility and reproducibility. An enormous advantage is the  
reduction of the optimization time. With a special adaptor1) it  
is possible to optimize the speakerphone system using just  
one link. The iterated procedure of “Building-up a line →  
Testing Deactivating the link Opening the telephone  
case Resoldering some RC elements Closing the case”  
is reduced to a comfortable computer session focusing on the  
real work: the optimization of the switching behaviour. The  
speakerphone maintenance/test function of the ARCOFI-SP  
supports the transparency of these modes which are  
mentioned above (refer to Application Hints for ARCOFI-SP  
Users).  
On the GOLDplusX baseband board all Siemens GOLDplus  
baseband devices are located including the system controller  
GOLD-µC (PMB 2706), the signal processor GOLD-SP  
(PMB 2707), the digital-to-analog conversion device GAIM  
(PMB 2905) and optionally the half-rate coprocessor  
GOLD-SX (PMB 2708). All required memory devices like  
FLASH memory and RAM are also found on this board.  
Suitable periphery like LCD display and keypad complete the  
system to a fully functional handset. The connector to the RF  
board carries all baseband I- and Q-signals in both receive  
and transmit direction and all RF-control signals from  
GOLD-µC.  
On the GOLDplus GSM RF board all the Siemens GSM RF  
devices are located including the transmitter PMB 2240, the  
receiver PMB 2405, the PLL PMB 2307 and the power  
amplifier consisting of CGY 92 and CGY 120.  
1) Refer to the application Note “Adaptor to program  
ARCOS-SP in customer hardware with Siemens ISDN  
PC User Board and ARCOS-SP PLUS”  
The GOLDplus demo system permits evaluation of all  
features of the GOLDplus chip set, both for the baseband as  
well as the RF part. By adding the PMB 2708 half-rate  
coprocessor the baseband may be upgraded optionally to  
half-rate operation. Critical parameters like power  
consumption or equalizer performance can be measured.  
Cost estimations for a customer handset can be based upon  
the bill of materials of the board.

A Typical GOLDplus Development Environment  
The development of a GSM handset splits up into  
development of GSM hardware and GSM software. Up to a  
certain stage development will run in parallel converging  
more and more prior to GSM type approval. Hardware  
development splits up into development of the baseband part  
and the RF part with the RF part requiring considerable  
experience and know-how.  
GOLDplusX Baseband Board  
Software Development Platform  
GOLDplusX board permits the customer getting started  
immediately with his GSM software development without  
having to wait for his own board prototypes. It provides an  
optimum debugging platform not only for the GOLD-µC C166  
system controller but also for the DSP cores if customer  
specific features have to be implemented in DSP firmware.  
Siemens along with its partners offers support for all stages  
of both hardware and software development permitting even  
newcomers to the GSM arena to get started quickly. For  
application of the GOLDplus chip set Siemens offers local as  
well as central support from headquarters in Munich. UK  
based Symbionics offers development of a complete GSM  
hardware according to customer requirements. For  
development of the RF hardware they build upon their  
profound RF experience. Munich based OPTIMAY offers  
mature GSM software with an easily customizable MMI.  
Besides getting quickly acquainted with the baseband  
functionality the board permits easy and complete control of  
the RF-chip set using the GOLD-µC controller functions. This  
is especially useful for evaluation and fine tuning of the  
RF-board functionality.  
The development of a GSM handset requires both optimum  
hardware and software development tools to meet time  
scales in a rapidly moving market.

Development Steps  
6.1  
A typical Development Environment  
for a DECT-Home System  
6.2.1  
Designing the Hardware  
In order to speed up this process, all the wiring diagrams are  
shipped with the boards. Major parts of the hardware shipped  
can of course be used for the final design. This is especially  
true for the SWUD 1300 RF board. The SWUD 3020E or  
SWUD 3025 board respectively has of course to be replaced  
by the PMB 2720X or PMB 2725X chip along with the  
E2PROM and the PMB 2920 chips. However, their  
interconnection can be taken from of the shipped wiring  
diagrams of the SWUD board.  
For DECT-home system development projects, there is a  
complete hardware and software solution available, which  
was designed to provide a first prototype to the customer. It  
actually covers all the necessary functional blocks and is fully  
operational, when connected to an analog telephone  
network.  
The effort was made in order to speed up the development of  
a DECT-home system and to provide a system hardware for  
immediate software development. Besides the tremendous  
know how, especially on the RF part, which is necessary for  
designing DECT phones, it is now the first time that a  
european standard protocol has to be matched. The DECT  
standard actually defines a very complex layered protocol.  
To implement that standard, a tremendous software  
development effort has to be made. This part of a DECT  
project is considered to be done in parallel to the final  
hardware design. The DECT-user board system provides a  
hardware development platform today which allows  
The SWUD 1100 board will typically need to be customized  
because it is very likely that one wants to use a different  
keyboard layout or a customized display etc.  
The major parts of the SWUD 1200 board can again be used  
to design a real base station telephone line interface.  
6.2.2  
Developing the Software  
A major task in the design work is the development of the  
DECT-protocol software. The effort is considered to be  
several man years. The SWUD 3500 setup is designed to  
support software development projects. The memory layout  
has been designed in close cooperation with Compiler and  
Debugger suppliers, with the result that C51 Debuggers can  
run in this environment.

The board can immediately load software, but the use of a  
high-level language debugger like the Keil (Franklin) TS51 is  
recommended. The monitor program of this third party  
software package is already shipped with the board to get  
user started more quickly. For most of the software  
debugging, an emulator is not really required. But in addition  
to the described software monitoring by a software debugger,  
there is also a hardware emulator available from Kleinhenz  
Electronic. It seems to be a good approach to use the  
software debugger for most of the daily work, but to have one  
emulator available for tricky real-time debugging and for final  
target system software implementations.

Tools for Universal RF Circuit Designs  
For the various RF circuits there are test boards available for  
evaluation. For distinct applications like the DECT-system-  
oriented family of user boards a complete RF application has  
been put together to complete the baseband tool set as a  
system solution.  
Besides hardware, there is also code available to support the  
development. There is a low level device driver software  
available which controls the chips.  
In addition to that, the source code package PRODECT adds  
a complete software implementation for a typical home  
system. This includes all the layers and saves the above-  
mentioned several man years. PRODECT is marketed as a  
one time buy out license. It implements the complete DECT  
standard, and by using PRODECT the customer’s software  
effort is decreased to about 10% for customized  
modifications.

• The Device Driver Software contains optimized Device  
Driver Modules especially written for the Communication  
IC ESCC2 from Siemens. These modules demonstrate the  
features, power and flexibility of the Siemens  
Communication ICs. The Device Driver Modules are  
completely written in C. They support the different protocol  
modes of the ESCC2, e.g. ASYNC, BISYNC, HDLC/  
SDLC.  
• An Application Program Interface (API) for the  
C language helps writing individual application software  
for the PC, communicating via a standard interface (C/l  
Mailbox Interface) with Device Driver Software on the  
coprocessor board. The program EXAMPLE gives a first  
idea of how to apply the C/I Mailbox API in a simple  
PC-application program.  
• The EASY532 tool comprises Downland, Debugging and  
Single Step test features, as well as Sequential Test  
capabilities. Its main purpose is to simplify the control and  
verification of Device Driver Software developed on the  
PC. This driver software can directly be downloaded on the  
coprocessor board for real-time applications. Furthermore  
the window driven Register Access Editor presents the  
Siemens Communication IC ESCC2 in a user-friendly  
manner. The time, that has to be spent for learning how the  
chip architecture looks like and how the chip works in  
principle is reduced to a minimum.

Datacom Application Board EASY532  
The Evaluation & Development System EASY532  
provides a hardware and software development tool for  
communication system applications with the serial  
communication controller SAB 82532 (ESCC2) using the PC  
as interface to the user. The relevant features of the  
SAB 82532 (ESCC2) are supported.  
Due to its original concept the Datacom ESCC2-Userboard  
EASY532 assists an engineer in developing his own  
applications. It reduces greatly the time spent for hardware  
and software development in offering not only a ready-to-use  
circuitry but also a plain and reliable software for operating,  
modifying, and testing the hardware according to one’s own  
pretensions and requirements. Thus using the Datacom  
ESCC2-Userboard EASY 532 in a short time leads to a  
stable hardware development; it provides level-1 and level-2  
software support while creating and testing own application  
software.  
The hardware is designed such as to fit into an expansion slot  
any PC/XT/AT or compatible. Thus after some simple  
configuring procedures (e.g. selecting l/O address by means  
of switches) and insertion of the board into the PC the circuit  
is just ready for use.  
• Application specific software can be developed by the user  
using so called “application modules” (apm.c,  
apm.h). This modules are linked to the Device Driver  
Software and downloaded on the Datacom Board, thus  
providing a high performance real time data  
This Datacom Application System comprises an SDA 80186  
coprocessor system, a PC Interface with 2-Kbyte Dual Port  
RAM and the Communication IC ESCC2 from Siemens.

a standard C cross development package for the 32-bit CPU  
it is possible to generate executable code which can be  
downloaded onto the communication subsystem with the  
EASY320 download utility.  
General Overview  
The Evaluation System for the MUNICH32 comprises  
modular hardware and software components especially  
optimized to demonstrate the excellent performance of the  
MUNICH32 device in a real communication subsystem.  
For a quick start using the MUNICH32 device in such a  
minimum reference system a sophisticated Windows user  
interface is built into the EASY320 PC-Evaluation Software  
especially designed for the MUNICH32 shared memory data  
structures. This user interface simplifies the direct access to  
the MUNICH32 device by mapping the MUNICH32 data  
structures to corresponding window structures on the PC.  
The hardware is divided into a 32-bit CPU base board and an  
appropriate extender board, which contains an individual  
system application with the MUNICH32 (e.g. Primary Rate  
Interface).  
The associated software structure for use with this  
hardware architecture consists of dedicated device driver  
software running on the communication subsystem and the  
corresponding Evaluation Software EASY320 on the PC host  
system.
