Abstract
A transmit-receive unit (TRU) which includes interface circuitry for interconnection with another TRU. Interconnect lines can carry PCM data to and from a line interface unit as well as share system information between the two transmit-receive units. An embedded operation channel data path multiplexer (EDP) also permits transmission of data between the transmit-receive unit and a bank controller unit over a service request lead.
