Abstract

PURPOSE:To make outgoing trunk connection test without using conventional channel and channel switching gate circuits, by providing a 2-line-4-line conversion circuit between an outgoing trunk test terminal and coding/decoding circuit. CONSTITUTION:A call from an outgoing trunk test telephone set 2 is detected at a subscriber circuit 3 and transmitted to a CPU13 via a controller 7 and a channel controller 11. This CPU13 receives a transmitted signal and starts a subscriber line circuit 16 to connect an outgoing trunk test terminal and a subscriber line conversion circuit 18. Relays in subscriber circuits and subscriber line drawing circuits are driven to connect the outgoing trunk test terminals and the circuit 18, and an output is incoming to an automatic response trunk of other station through an outgoing trunk circuit 12. Thus, for the outgoing trunk connection test, the use of call channel of a slave station to a master station is not necessary and the control of channel selector switch is made unnecessary to make easy the test.
