Kind Code:
A
Abstract:
A time-division switching system for switching data words from data word sources received in channels of a time-multiplex line where a first plurality of data word sources uses a channel only once every n channels and a second plurality of data word sources uses a channel once every m channels where m is less than n and n is not an integer multiple of m. The switching system operates in response to control words sequentially provided by a control word source. The control word source of the disclosed embodiment comprises a first storage arrangement having n storage locations for storing control words and a second storage arrangement having m storage locations for storing control words. A storage reading circuit substantially simultaneously reads the contents of one storage location of both storage arrangements sequentially. A selection arrangement receives the control words from the storage reading circuit and transmits a predetermined one of the two control words se read to the time-division switching system for control thereof.
