If the PABX does not support V.8/V.34 protocol
procedure, set this bit to "1" to disable V.8.
Example: If "0" is the PSTN access code, set bit
0 to 1. When the machine detects "0" as the first
dialed number, it automatically disables V.8
protocol. (Alternatively, if "3" is the PSTN access
code, set bit 0 to 1.)
COMMENTS

Example: If "8" is the PSTN access code, set bit
0 to 1. When the machine detects "8" as the first
dialed number, it automatically disables V.8
protocol.
