TRANSMISSION TIME
■ Simple Transmission Time
The simple transmission time means the time between the
start of data sending from the master station and the end of
data sending from the local station. It means 1 cycle of data
transmission between the master station
and the local station. It does not mean the time required for
an input signal to be output.

Maximum load current: 100 mA
Internal series resistance: approx. 20 Ω including return
Leakage current
Between B – C: ≤50 mA at ±110 V DC
Between B or C – A: ≤50 mA at ±55 V DC
Between each line – G: ≤10 mA at ±140 V DC
■ 300 BPS TYPE
■ How to Calculate the Simple Transmission Time
•Transmission Rate 50 bps
Simple Transmission Time (sec.)
•Modem (model: MOD2-K)
= (No. of data bytes from master station + No. of data
bytes from local station) × 0.22 + 0.5 × 2
•Transmission Rate 300 bps
Telephone circuit: NTT leased circuit, 3.4 kHz
Sending level: -7 to -15 dBm
Receiving level: -40 dBm
Simple Transmission Time (sec.)
Transmission rate: 300 bps (half-duplex)
Modulation: conform to ITU-T V.21
No. of circuits: 1
= (No. of data bytes from master station + No. of
data bytes from local station) × 0.037 + 0.2 × 2
■ Effective Transmission Time
Approval No.: D01-0730JP
The effective transmission time means the time required for
a change of an input signal to affect its output signal. It
