General Information
Throughput
The sending time is calculated in the following formula:
Sending time = Call setup time + Tm + (N x Tp) + {(N-1) x Tn} + Tu (sec)
(N: Send quantity; Tp: Image transmission time)
Cable Characteristics
With pseudo cable from 0 to 15km, the highest speed shall be guaranteed for communication with
V.17, V.29, and V.27ter. For V.34, 33600bps communication speed shall be guaranteed from 0 to 2km,
31200bps or higher communication speed from 2 to 9km, and 19200bps or higher communication
speed from 9 to 15km.
Communication Load Characteristics
Data error characteristics for noise and cable loss during communication are as follows:
Error rate (Error frequency/Total communication quantity)  1/500
Incoming Call Level
Under ideal conditions (flat line, no noise, and no other line stress), normal communication shall be
guaranteed in the range from -3 through -43dBm.
For V.17, V.29, and V.27ter, the highest speed shall be guaranteed in the range from -6 through -
43dBm. For V.34, 33600bps communication speed shall be guaranteed in the range from -9 through -
19dBm, and 16800bps or higher communication speed in the range from -19 through -43dBm.
For V.34, normal communication shall be guaranteed in the range from -9 through -43dBm.
