Setting up to fax while behind a PBX

If the printer is being used in a business or office, it may be connected to a Private Branch Exchange (PBX) telephone
system. Ordinarily, when dialing a fax number, the printer waits to recognize the dial tone and then dials the fax
number. However, this method of dialing may not work if the PBX telephone system uses a dial tone that is not
recognizable to most fax machines. The "Dialing while behind a PBX" feature enables the printer to dial the fax
number without waiting to recognize the dial tone.
