Abstract

PURPOSE:To allow even a system which performs private broadcasting coupling under dial call control to perform extension originating during private broad-casting, by storing the output of a dial counting control part, and releasing the counting control part from being acquired. CONSTITUTION:A dial signal inputted from a telephone set 22 to a counting control part 7 is outputted from an output part 8 to a private broadcasting coupling control part 4. This output is stored in a storage part 29 corresponding to an extension circuit 11 in origination through an input gate 35, and further outputted from the storage part 29 to close a gate 35. At the same time, a voice gate corresponding to the circuit 11 is opened to hold the circuit 11 in readiness for answering. A voice sent out of the telephone set 22 is supplied to external broadcasting facilities 2 to voice a broadcast through a loud speaker 1. At this time, the circuit 11 is in an answer state the acquisition of the control part 7 is released, and other extension circuits 12 and 13 are released from being locked out. Another telephone set, e.g. a telephone set 24 performs extension origination through the circuit 12, and then the control part 7 is acquired to perform lock-out control over other extension circuits, allowing a normal extension call.
