ABSTRACT:
A control word generation method and a structural arrangement of a control word source for use in a time division switching system for serving multirate data stations. The control word source includes a first memory that stores a first plurality of path-definition words defining communication paths for nonsubrate channels and a plurality of storage reference words. The control word source also includes a second memory that stores a second plurality of path-definition words defining communication paths for subrate channels. The first memory is read sequentially and control words are derived from each of the read path-definition words. A location generator responds to timing pulses generated by a network clock and to each of the plurality of read storage reference words by generating a location signal defining a storage location of the second memory. The second memory is read in response to this location signal and a control word is derived from the path-definition word thus read.
