1. Introduction:

The in-Line Micro filter has been specifically designed to implement the functionality of low

pass filter in G.Lite system. G.Lite technology is similar to full rate ADSL in using DMT

technology but operates at a lower data rate of up to 1.5Mbps downstream and 512Kbps

upstream,depending on line conditions and lengths.

ADSL Lite is proposed as a lower speed version of ADSL that will eliminate the need for

telecom to install and maintain a premises based POTS splitter. Recent field trials of DSL Lite

equipment jointly carried out by a group of manufacturers and a North America network

operator has proved the technology, achieving maximum data rate for distance up to 15000

feet, It was found necessary to include one or more low pass filters in series with the POTS

terminals in order to reliably achieve maximum data rates. For POTS voice band service , the

low pass filter provide protection from ADSL signal which may impact through non-line or

other effects remote devices(handset, fax, voice band modem etc)and central office

operation . For ADSL signal , it also provide protection from the high frequency transient and

impedance effect that occur during POTS operation(ringing transients , on-hook, off-hook

transient and so on).

Because the POTS splitter connects directly to the subscriber loop media , it must also

provide some protection for externally induced line hits or faults which could damage any

attached equipment or endanger humans interacting with the installed equipment. The circuit

protection will be provided mostly by standard central office line protection means and

additional protection measures built into pots splitter to protect against line overstress which

could damage the splitter itself.

4.4. DC characteristic :

All requirement of this specification can be met in the presence of all POTS loop currents

from 0mA to 100mA. This in line filter can pass POTS tip-to-ring dc voltages of 0V to 105V

and ringing signals of 40V to 106Vrms at any frequency from17Hz to 23Hz with a dc

component in the range from 0V to 105V. The dc resistance from tip-to-ring at the line port

interface with the phone interface shorted, shall be less than or equal to 25 ohms for one

splitter. The DC resistance from tip-to-ground and from ring-to-ground at the POTS

interface with the U-R interface open shall be greater than or equal to5 Megohms. The

ground point shall be local building or green wire ground. As an objective , the dc resistance

should exceed 10MW.

4.5. Test method :

4.5.1. On hook insertion loss :

The insertion loss of a device connected into a given transmission system is defined as the

ratio, expressed in dB, of the load power available(before and after insertion ) delivered to

the output network beyond the point of insertion at a given frequency. In general , the

insertion loss is defined as the ratio, expressed in dB of the power delivered to a load with

the circuit in place and the power delivered to a load without the circuit in place. The added

insertion loss shall be measured using the test up in figure 3. For measuring POTS band

insertion loss for single filter module also a single filter wit four added parallel load filters.

General Insertion loss equation can be expressed as following. Insertion loss = 20 log

½V2 / V1½ dB where

V1 = the measured voltage value of load without LPF in circuit.

V2 = the measured voltage value of load with LPF in circuit.

4.5.3. Return loss :

Return loss measure the amount of energy that is lost due to reflection which resulted

from impedance mismatching at the interface. Return loss is essentially defined as the

ratio of the power incident upon a given transmission system to the power reflected

caused by impedance mismatch with respect to reference impedance at the interface

between source and device.Return loss figure are a function of the impedance of the

circuit involved and are therefore frequency dependent. These impedance must be

closely maintained in order to reduce the possibility of undesirable reflection and echoes

which in long distance circuit the telephone user or destroy the data being sent. To

perform the return loss test ,open ,short, load calibration must be done prior

measurement while the LCZ impedance Analyzer being selected in impedance mode.

Return loss is general expressed in decibels. General Return loss equation as below:

Return loss = 20 log ½Z_L+ Z_M/ Z_L- Z_M½dB

Where Z_L= the reference impedance

Z_M= the measured impedance
