ABSTRACT:
A telecommunication facsimile set accommodating transmission and reception of facsimile data during a telephone conversation on a telephone handset built into a facsimile machine, and placement of an established connection between the telephone handset built into the facsimile telecommunication set to put the connection on hold in order to talk with another caller via a second telephone line. The facsimile telecommunications set may be constructed with a microprocessor controller sensing both telephone signals and user activated signals, and sending control signals which activate circuit switching relays causing either the facsimile telephone handset or the facsimile modem to connect to either of the two telephone lines.
