  • Patent number: 5214650
    Abstract: A data adapter for simultaneously providing a low speed channel, a first high speed data channel, and a second high speed channel over a two wire connection; the two wire connection connects the data adapter to a telephone system. The data adapter includes a line transceiver connected to the two-wire connection, the line interface provides a full duplex transmission link with the telephone system over the two-wire connection. A telephone interface converts data between the first high speed channel and a telephone instrument. A rate adapter converts data between the second high speed channel and a data processing equipment. A protocol controller performs a packet protocol on the low speed channel, and routes the first high speed channel to the telephone interface and the second high speed channel to the rate adapter.
