Abstract:
An apparatus for communicating data between a communications loop and a backplane, comprising:a first transceiver circuitry operative to transmit and receive voice-band modulated data over the communications loop;a backplane interface configured to provide physical interconnection to the backplane;a backplane interconnection circuitry operatively coupling the first transceiver circuitry and the backplane interface to each other for data transmission, the interconnection circuitry being operable to receive digital data from the first transceiver circuitry and transmit the digital data over the backplane, and to receive digital data from the backplane and provide it to the first transceiver circuitry for transmission over the communications loop;a signaling circuitry operative to transmit and receive POTS call control signals over the communications loop; anda data cell processing circuitry coupled to the first transceiver circuitry and to the backplane interconnection circuitry, the data cell processing circuitry operative to receive a data cell from the backplane interconnection circuitry, extract data from the payload field of the received data cell, and send the extracted data to the first transceiver circuitry.
