12.2 Telephone

12.2.1 Cable Characteristics

With pseudo cable of 0 through 15Km, the highest speed is guaranteed for communication with V.17m,
V.29, and V.27ter respectively. As for V.34, 33600bps or higher communication speed is guaranteed
with 0 through 2Km cable, 31200bps or higher communication speed with 2 through 9Km cable,
19200bps or higher communication speed with 9 through 15km cable.

12.2.2 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

12.2.3 Incoming Call Level

Under ideal conditions (flat line, no noise, and no other line stress), normal communication is
guaranteed in the range from 0 through 43dBm. As for V.17, V.29, and V.27ter, the highest speed is
guaranteed in the range from -6 through -43dBm. As for V.34, 33600bps or higher communication
speed shall be guaranteed in the range from -6 through -19dBm, 16800bps or higher communication
speed in the range from -19 through -43dBm.
