1. A communications transceiver for transmitting and receiving data to and from an ISDN comprising:

  • computer means responsive to a computer interrupt signal for generating a computer address and control signal, and for outputting and receiving data signals in data byte format;

    interface circuit means having a receive port and a transmit port for connection to a network termination device to receive and transmit ISDN B-Channel information, said interface circuit means being responsive to said computer address and control signal and operative to receive said data signals in data byte format from said computer means, and to process said data signals without changing their bit organization, and to insert the data signals into the B-Channel of ISDN frames of an ISDN signal format for output via said transmit port to said network termination device, said Interface circuit means being further operative to receive ISDN frames from said network termination device via said receive port and operative to generate said computer interrupt signal and to extract data bytes from the incoming ISDN frames and output said data bytes to said computer means.
