ABSTRACT:
A time division communication system is constructed with modular time division switches. The system includes 2n switch modules (n is a positive integer), and each switch module is composed of m line control units (m is a positive integer) for accomodating m lines and a time division switch control unit capable of controlling 2m line control units. The switch modules are assembled in pairs, and cross connections are provided between the switch modules of each pair to enable the respective time division switch control units to mutually send and receive time-division multiplexed information. In addition, the input and output terminals of the corresponding time division switch control units of the respective switch module pairs are interconnected so that respective ones of the module pairs may mutually send and receive time-division multiplexed information.
