COMMENTS
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.)
COMMENTS
Refer to communication switch 1B.
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. (If "9" is the PSTN access code, use bit
1.)
Do not change the settings.
COMMENTS
(0, 0): The monitor speaker is disabled all through
the communication.
(0, 1): The monitor speaker is on up to phase B in
the T.30 protocol.
