ABSTRACT:
A time-space-time-space-time switching network is composed of a subscriber connected to a remote unit network having a time and space switching stage. The subscriber is then connected to a central office switching system having a time-space-time switching network. Alternatively, the switching network may comprise a subscriber locally connected through the time-space-time switching network of the central office switching system to the space and time stages of the remote switching unit. The remote unit network and the central office network are interconnected by a number of digital spans. In addition, the remote unit and the central office each provide for local to local traffic. That is, traffic which is transmitted only within its own switching network.
