ABSTRACT:
A digital subscriber controller having a number of analog ports and digital ports which can be programmed via an external microprocessor to establish time-division multiplexed bidirectional data paths between three subscriber-selected ports designated as "sources" and three subscriber-selected ports designated as "destinations". Among the ports is a line-interface port having two 64 kilobit-per-second voice/data channels and a 16 kilobit-per-second data control channel. Among the digital ports is a three-channel serial interface port and a two-channel microprocessor interface port. An analog port is also provided at which a variety of audio transducers may be connected. The controller includes a line interface unit, a data link controller which processes data channel information present at the line interface unit, a main audio processor, a microprocessor interface, and a multiplexer which establishes the data paths selected by the subscriber.
