Abstract

PURPOSE: To prevent a waste call issuing operation performed by detecting the available state of a terminal in use and displaying it on another terminal in a system where one of plural telephone sets and a facsimile terminal is connected to one telephone line.
CONSTITUTION: One of the plural telephone sets 1, 2 and the facsimile equipment F not shown in figure is connected to a pair of telephone lines L1, L2 with a CML relay 5, respectively. The telephone sets 1, 2 and a call signal detection circuit 9 are connected to lines L3, C4 in parallel. The modem of facsimile equipment is connected to lines L5, L6 via an insulating transformer 6. Off-hook detection circuits 3, 4 are provided in series at the telephone sets 1, 2, and a relay RL1 or RL2 is closed by performing off-hook, and a LED 7 or 8 is lit. The output signal CI of the call signal detection circuit 9 is inputted to the control part of the facsimile equipment, and the LEDs 7, 8 are provided in the neighborhood of the operating part of the facsimile equipment and the telephone sets 1, 2. In such a way, the fact that another terminal is being used can be displayed, which prevents the waste call issuing operation performed.
