Connecting to a PBX

A PBX (Private Branch Exchange) is a private telephone system used to route internal calls. If you have to dial a prefix (access digit) to get an outside line, then your line is connected to a PBX.

If you are connecting your fax machine to a PBX, follow the instructions below. It can then detect the access digit at the beginning of phone numbers you dial or program, and automatically waits for a dial tone before dialing the rest of the number.
