Abstract

PURPOSE:To obtain a convenient and inexpensive telephone set for a remote supervisory controller by using a subscriber telephone for the talking with the remote supervisory controller so as to utilize various functions of the subscriber telephone set. CONSTITUTION:A subscriber telephone set 14 is connected to a hook state detection circuit 22 and a dial detection circuit 24 via a current supply circuit 20. The circuit 22 is connected to a dial tone generating circuit 23 via a timer circuit 28 and the circuit 23 is connected to the set 14 via a 2/4-wire exchange circuit 21. A call signal detection circuit 26 connects to a call tone circuit 27 driving a calling bell and the circuit 27 is connected to the set 14 via the circuit 20. Thus, the subscriber telephone set is used as the telephone set of the remote supervisory controller to utilize the various functions of the subscriber telephone set.
