ABSTRACT:
Time-switch control-store arrangements for use in a digital switching system of a time division multiplex telecommunication system of the type defined in which the time-switch control-store arrangements serve corresponding receive and transmit time-switches of a superhighway group and a single connection control-word in the time-switch control-store is employed twice in a superhighway frame, once for reading the receive time-switch information character in respect of one simplex path and once for writing the corresponding transmit time-switch information character in the same m-channel multiplex in respect of another simple path, the phase difference between the said reading and writing being F/2 + D where F is the total number of cross-office time-slots in a superhighway frame, and D is the finite propagation delay incurred in the transmission of an information character over a simplex path.
