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.
