ABSTRACT:
A wideband communication facility is established via a switched network between calling and called terminals. The wideband facility comprises a number of segments, each segment including a plurality of narrowband time division multiplex channels having a total bandwidth at least equal to the bandwidth of the wideband facility. A switching system of the network interconnects the wideband facility segments and assembles all the data received in a given time frame from one segment into the single time frame for transmission to another facility segment. Additional buffer memories are added to the initial and final stages of a time-space-time switching network to insure that all the data received in one time frame from a given facility segment is assembled only into the same time farme for transmission on an outgoing facility segment.
