PURPOSE:To use in common one subscriber line for plural terminals by providing a slave number corresponding to plural facsimile terminals of the same telephone number, requesting the transmission of the slave number with talkie to an incoming call and executing the selection of outgoing connecting any of outgoing requests of plural terminals and the selection of incoming connecting only a terminal of the received slave number. CONSTITUTION:A call signal from an incoming side exchange 2 activates a relay R via a relay contact (b). When the exchange 2 detects a loop including the contact (b), a talkie 31 is connected to a telephone set TELS in the path of incoming side exchange 2-outgoing side exchange 1, and an additional dial is requested to the outgoing subscriber of the telephone set TELS from the talkie 31. The outgoing subscriber dials additionally a slave number ''0'' of a desired terminal. The number ''0'' is received by a PB signal receiver 32 via a hybrid 30. A priority selecting circuit 33 activates a relay RN0 and contacts n0, s0 corresponding to the PB signal and a call signal is transmitted from a call signal transmission circuit 34 to a telephone set TEL0. The priority selecting circuit 33 inhibits the operation of other relays when one of relays N0-N9 is activated. |
