What is a fax line? definition and usage

LAST UPDATE: March 5th, 2018


A fax line is a phone line that is primarily intended for fax use. It can also be used as a regular phone line.


Fax lines are phone lines that are attached only to a fax machine.

The only difference between a phone line and fax line in regards to infrastructure is that a fax line has to be a traditional analog phone line. Many phone lines have migrated to VoIP or internet-enabled technology, most of it incompatible with fax.
