Abstract

PURPOSE:To perform a process by invariably the same control system regardless of the circuit capacity and function of a switchboard, by providing the system in common with a control circuit for controlling a channel switch from several processors. CONSTITUTION:To line-side terminals of switching network 51, attendant boards 311...31n are connected by way of extension telephone sets 111, 112... and attendant-board control circuits 411...41n, and switching networks 52...5m are also provided in the same way. Here, the reception and transmission of various control signals of networks 51...5m are controlled by signal control processors 71...7m, which consist of attendant-board control blocks, line control blocks, connection- state memory control blocks, etc., and switch control circuit 104 is provided to the system in common. Consequently, processes can be performed by invariably the same control system regardless of the circuit capacity and function of the switchboard.
