Abstract:
A control system of a 3-staged time-division switch, constituted by a space switch module including a plurality of second stage space switches and a plurality of time switch modules, each including a first stage time switch coupled with one of said second stage space switches by a junctor highway and a third stage time switch coupled with one of said second stage space switches by another junctor highway, for forming a T-S-T (time switch-space switch-time switch) 3-staged structure switching network used in a multi-processor type digital switching system, said control system comprising:a control means provided in each time switch module for connecting a highway coupled with an input of said first stage time switch, instead of said junctor highway coupled with one of said second stage space switches, to the input of said third stage time switch for constituting a one-staged time switch switching network when detecting said space switch module being in a faulty condition.
