COMMUNICATION SIGNAL RELAY DEVICE IN MOBILE STATION CENTER

摘要

PURPOSE: A communication signal relay device in an MSC(Mobile Station Center) is provided to simply construct the MSC, and to simultaneously control a transmission speed adaptor and an LAPF(Link Access Procedure to Frame mode bearer services) protocol processor. CONSTITUTION: A transmission speed adaptor(2) adapts communication signals having each different transmission speed. An LAPF(Link Access Procedure to Frame mode bearer services) protocol processor(4) receives the communication signals, and processes the communication signals to be in accord with protocols. A controller simultaneously controls a transmission speed processor and the LAPF protocol processor(4). A sub highway line(8) divides the communication signals, and supplies the divided communication signals to subscribers. The first high level link controller(10) controls to transmit the communication signals transmitted from the sub highway line(8) to the controller(6) at a high speed. The second high level link controller(18) controls to transmit the communication signals transmitted from the transmission speed processor to the controller(6) at a high speed.
