ABSTRACT:
Serial link adapter to be used in a communication controller comprising data handling means (DHM), said adapter allowing the communication controller to be attached to a multiplex serial link carrying data and non coded information bits in dedicated slots.
In line adapter LA1 receiving means RCV1 are connected to serial link carrying data and non coded information slots. The receiving means comprises a routing arrangement for sending the data slot bits to the data handling means of the controller and the non coded information slot bits a high speed bus HSB1. Transmitting means Xmit1 are connected to high speed bus HSB2 and to the data handling means and comprises means for sending the data and non coded information slot bits in dedicated slots on the serial multiplex link MPX-T. Line adapter LA2 comprises means which are similar to the receiving and transmitting means in adapter LA1 and may be connected to the private branch exchange located in the same site as the communication controller.
