Chapter 6 General
6.1.11.2 Cable Characteristics
With pseudo cable of 0 through 15Km, the highest speed is guaranteed for communication with V.17,
V.29, and V.27ter respectively. As for V.34, 33600bps communication speed is guaranteed with 0
through 2Km cable, 31200bps communication speed with 2 through 9Km cable, 19200bps or higher
communication speed with 9 through 15km cable.
6.1.11.3 Communication Load Characteristics
Data error characteristics for noise and cable loss during communication are as follows:
Error rate (Error frequency/Total communication quantity) ï‚£ 1/500
6.1.11.4 Incoming Call Level
Under ideal conditions (flat line, no noise, and no other line stress), the normal communication in the
range of -3 dBm to 43 dBm shall be guaranteed.
As for V.17, V.29, and V.27 ter, the highest speed shall be guaranteed in the range of -6 dBm to -43
dBm. For V.34, the communication of 33600 bps or more shall be guaranteed in the range of -9 dBm to
-19 dBm, as well as that of 16800 bps or more in the range of -19 dBm to -43 dBm.
However, the normal communication in conformance to V.34 shall be guaranteed in the range of -9
dBm to -43 dBm.
