Abstract
PURPOSE:To make it possible to confirm and diagnose the performance of a remote station exchange function without dispatch of a mainternancer to the remote station by connecting temporarily a service call in the remote station to the digital channel of the remote control time division switchboard by the control of the master station. CONSTITUTION:A remote control time division switchboard is provided which is connected to the master station time division switchboard by a digital circuit and takes partial charge of the connection processing normally by the control of the master station and performs the exchange processing of only remote service call by intra-office exchange processing function part 1 when the connection processing dependent upon the control of the master station is impossible, and insertion control circuit 4 connected to decoding circuit 105 is provided in the digital circuit which connects the master station and function part 1. Further, originating subscribed artificial circuit 2 having the receiving function of response tone and incoming subscriber artificial circuit 3 having the function of signal receiving are provided. Then, when a channel designated by the master station is diagnosed through control circuit 107 the channel from multiplexing separator circuit 112 of function part 1 is temporarily connected to circuit 105 by control circuit 4, thus confirming performance.
