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.)
