Abstract

A modem (5) samples, from line (1), signals representing the signals conveyed by said line (1) without interfering with them. A micro-controller (6) controls a switch (2) in response to the signals samples so that, in the absence of a call, the line (1) is connected to a fax machine (4). If a call is followed by protocol signals coming from a distant fax machine, the micro-controller leaves the line (1) connected to the fax machine (4). If not, it controls a ringing generator (7) of the telephone set (3) and connects the line (1) to it, if the receiver has been unhooked. The invention permits a subscriber to use the same telephone line for faxes and conversations without having to carry out switching operations.
