Fax machines work much like old dial-up modems worked; they transmit data – text and images, in this case – through the phone lines to another fax machine somewhere else in the world. The second fax machine interprets the data coming in from the telephone line and then prints it out onto paper. Fax machine operation can be interrupted by DSL lines, however, because the DSL signal is also transmitted through phone wiring. This can result in a loss of data in the fax if steps are not taken to prevent it. Fortunately, this is not a difficult thing to fix. Tips Writer Bio
