Extension access code (0 to 7) to
turn V.8 protocol On/Off
0: On
1: Off
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 3 to 1.)
