Abstract

PURPOSE:To realize a stand-by switching in every group by providing a stand-by switch circuit in every group for the junctor switches divided into several groups, in a time-division channel. CONSTITUTION:In the conventional technique, a junctor stand-by switch circuit is provided in every channel module. In this invention, however, the junctor stand-by switch circuit C1 and C2 which are capable of a stand-by switching are provided in every junctor group that is identical with a gate matrix divided in a small scale.
