Simultaneous voice and data system using the existing two-wire inter-face

A data adapter for simultaneously providing a low speed channel, a first high speed channel, and a second high speed channel over a two wire connection, said two wire connection connects said data adapter to a telephone system, said data adapter comprising:

• a line transceiver means connected to said two-wire connection, said line transceiver means provides a full duplex transmission link with said telephone system over said two-wire connection, said full duplex transmission link comprised of said low speed channel, said first high speed channel, and said second high speed channel;
• a protocol controller means connected to said line transceiver means, said protocol controller means performs a packet protocol on said low speed channel and, said protocol controller means routes said first high speed channel to a telephone interface means and said second high speed channel to a rate adapter means;
• said telephone interface means connected to said protocol controller means, said telephone interface means converts data between said first high speed channel and a telephone instrument;
• said rate adapter means connected to said protocol controller means, said rate adapter means converts data between said second high speed channel and a data processing equipment, said rate adapter means performs a rate adaption protocol while converting said data between said second high speed channel and said data processing equipment, said rate adapter means including a signal processor means arranged to perform said rate adaption protocol, said rate adapter means including a Read Only Memory (ROM) means for storing a rate adaption protocol program used by said signal processor means, and a Random Access Memory means used by said signal processor means for temporary storage;
• and
• a processor means connected to said line transceiver means, said protocol controller means, said telephone interface means, and said rate adapter means, said processor means arranged to receive and transmit messages through said protocol controller means over said low speed channel to said telephone system, and in response to information received over said low speed channel, and information received from said rate adapter means, said processor means controls said data adapter.

A data adapter for simultaneously providing a low speed channel, a first high speed channel, and a second high speed channel over a two wire connection, said two wire connection connects said data adapter to a telephone system, said first high speed channel carries a digitized analog signal from, and to, a telephone instrument and said second high speed channel carries data from, and to, a data processing equipment, said data adapter comprising:

• a line transceiver means connected to said two-wire connection, said line transceiver means provides a full duplex transmission link with said telephone system over said two-wire connection, said full duplex transmission link comprised of said low speed channel, said first high speed channel, and said second high speed channel;
• a control interface means connected to said line transceiver means, said control interface means arranged to provide a communications channel to said line transceiver;
• a protocol controller means connected to said line transceiver means, said protocol controller means performs a packet protocol on said low speed channel and, said protocol controller means routes said first high speed channel to a telephone interface means and said second high speed channel to a signal processor means;
• said telephone interface means connected to said protocol controller means, said telephone interface means converts data between said first high speed channel and said telephone instrument;
• said signal processor means connected to said protocol controller means, said signal processor means arranged to perform a rate adaption protocol on said second high speed channel and said data from, and to, said data processing equipment;
• a first serial transceiver means connected between said signal processor means and said data processing equipment, said first serial transceiver means converts data between said signal processor means and said data processing equipment;
• a parallel to serial converter means connected to said signal processor means, said parallel to serial converter means accepts parallel data from said signal processor means and converts said parallel data to serial data;
• a second serial transceiver means connected between said signal processor means and said parallel to serial converter means, said second serial transceiver means arranged to receive said serial data and extract a complete data byte from said serial data, said complete data byte is then converted to a parallel format and transmitted to said signal processor;
• an interprocessor interface means connected to said signal processor means, said interprocessor interface means arranged to provide a communication channel to said signal processor means;
• and
• a processor means connected to said control interface means, said protocol controller means, said telephone interface means, and said interprocessor interface means, said processor means arranged to receive and transmit messages through said protocol controller means over said low speed channel to said telephone system, and in response to information received over said low speed channel, and information received from said signal processor means through said interprocessor means, said processor means controls said data adapter, said processor means controls said line transceiver means through said control interface means.
