6.1.35.8 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)

6.1.36 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.

6.1.37 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

6.1.38 Incoming Call Level

Under ideal conditions (flat line, no noise, and no other line stress), normal communication shall be guaran-
teed 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.
