ABSTRACT:
A remote data link controller is disclosed for formatting, transmitting and receiving control data over high speed digital data links between the peripheral processors of a plurality of telecommunications switching systems. The remote data link controller includes a microprocessor controlled data link processing circuit which is time shared among all of the digital data links. The remote data link controller processes one transmit and one receive message byte during a reformatting cycle for each digital data link. It stores any intermediate results in a temporary memory than proceeds to service the next digital data link. The remote data link controller fetches intermediate results from the temporary memory, processes the data and stores the next intermediate results in the temporary memory until it has completely serviced all of the digital data links.
