ABSTRACT:
A telecommunication switching network is described which uses a multistage reverse trunking arrangement for switching single channel subscriber lines on a four wire basis. The switching network is constructed as a pulse code modulated (PCM) time division multiplex (TDM) network. A termination circuit is connected to each subscriber line, and at its output, to a TDM trunk. A switching module is provided for a group of such termination circuits; the module includes a multiplexer and a demultiplexer. Each of the aforementioned TDM trunks is connected at one end to the input of a multiplexer and at the other end to the output of the demultiplexer. An addressable storage for time position conversion is provided in the switching module. The input of the storage is connected to the output of the multiplexer, and its output is connected to the input of the demultiplexer. The other multiplexer inputs and demultiplexer outputs are connected by further TDM trunks to another switching network module of a succeeding stage.
