Abstract

PURPOSE:To shorten a control time at an outgoing time and a calling time, by reserving respective links to be used for calling and the route of a secondary switch even at a call terminating time in a call control system to control a speech path composed of a three steps-switch circuit. CONSTITUTION:A switch module to constitute a three steps-switch circuit network is composed of input switches 1-3, secondary switches 4-6 and output switches 7-9. Then, the route to link an A link between the input switches 1-3 and the secondary switches 4-6, a connecting path in the secondary switches 4-6 and a B link between the secondary switches 4-6 and the output switches 7-9 is held in advance. Thus, when the reserving route to satisfy a condition is not found when first retrieval is executed, the reserving route in an idle condition is retrieved and a route changing means 115 is driven. Next, the two routes of a route (x) and (x') and a route (y) and (y') are switched to a route (x) and (y') and a route (y) and (x') and the route between an outgoing terminal gamma and an incoming terminal delta is secured. When the calling is ended, the connecting of the secondary switch the calling is ended, the connecting of the secondary switch is held to release the input and output switches.
