Abstract

PURPOSE:To eliminate necessity of installing a feeding circuit exclusively used for a communication terminal equipment in a main unit and make it possible to connect the communication terminal equipment to the main unit using simple constitution by starting a talking terminal equipment such as a facsimile unit, etc.,by extension call and operating by station power ource after starting. CONSTITUTION:Main wire/extension switching relays 21 and 22 are normally switched to extension side. Incoming signals from a trunk line 1 are detected by a detecting circuit 23, and a control signal for generating incoming tone is sent from a controlling circuit 28 to a key telephone set 5. When a user makes a reply by off-hook, the switching relay becomes trunk line side and becomes the state of call. However, in case of call of a facsimile unit 9, extension number of the facsimile unit is dialed holding the trunk line in a holding circuit 20. Then, the controlling circuit 28 sends a control signal to an incoming signal generator 81 and inputs an incoming signal of 20 Hz through a change- over switch 80, and the facsimile unit replies at once by automatic off-book operation. When a user of the key telephone 5 makes on-hook, the switching relay 21 is switched to the trunk line side, and the trunk line held in a holding circuit 26 is connected to the facsimile unit 9.
