Time-division multiplex switching network

摘要

A time-division multiplex switching network is constructed of units designed as time stages which operate blocking-free and which are multiply divided. A plurality of units of identical structure to a plurality of switching units of a switching network portion is assigned to each switching network portion, the plurality of units being operated as multiplexers at which the outgoing time-division multiplex lines are connected and whose normally non-utilized outputs can be connected by way of switches to other time-division multiplex lines extending from other switching network portions. Upon failure of the latter switching network portions, the switches are closed for rerouting the traffic through the system.
