ABSTRACT:
A telecommunication switching system including a plurality of terminal circuits each associated with a common control device. The common control device is coupled to a switching network through two interface circuits which operate asynchronously. The control device includes a processor and control means to successively allocate the processor to each of the terminal interface circuits. This uniquely simple solution requires only one control device while providing the high reliability that may be achieved through the use of two interface circuits.
