ABSTRACT:
In an apparatus to couple a plurality of line interfaces with corresponding modems ports, status and control signals are time-division-multiplexed (TDM) into a data stream before being exchanged between the devices. This substantially reduces the number of communication wires required and allows for several modems to be coupled in close proximity to a line interface card. Packet recognition circuitry coupled to the modem ports insures that signals in the TDM data stream are transmitted to the appropriate modem ports.
