Circuit arrangement for time-division-multiplex telecommunication exchanges, particularly for PCM telephone exchanges with time-division highways of which the time channels are used partially for the transmission of data and partially for the transmission of signalling information

摘要

Switching of data transmitted over a signal channel per time-division multiplex and the single super pulse frame (a super pulse frame corresponds in duration to the duration of a larger number, eg 16, successive Puisrahmen) signaling information on the switching of the communication channels serving time-division multiplex switching matrix. An information storage (D), two latches (H, K) is assigned, one of which (H) is designed to convey the message information and operates with a corresponding one pulse frame revolution cycle, and the other of which (K) of the exchange of signaling information is used and works with a super pulse frame corresponding circulation cycle. The second latch (K) is incremented (H) with each full revolution of the first latch.
