Circuit arrangement for T.D.M. telecommunication exchange system, comprising T.D.M. lines whose time channels serve partially for message connections and partially for the transmission of signalling information |
摘要 |
Signaling information is transmitted over a signal channel per time-division multiplex and combined into super pulse frames each of which corresponds to the duration of a larger plurality of successive pulse frames, over the time-division multiplex switching matrix serving for the switching of message channels. A first information memory has a turnover cycle corresponding to a pulse frame and serves for the intermediate storage of message sub-information, whereas a second information memory has a turnover cycle corresponding to a super pulse frame and serves for the intermediate storage of signaling sub-information. A common holding memory assigned to both information memories regularly interrupts the read operation of the first information memory for the purpose of inserting a signaling sub-information read from the second information memory.
