A modem for processing telephone calls includes a line interface for coupling the modem to a telephone line and a computer interface for coupling the modem to a host computer. A processor in the modem between the line interface and the computer interface receives signals running between the telephone line and the host computer. Both the signal processing session and the control processing session required to process the signals are implemented on the single processor.

Modem with integrated control processor and digital signal processor

An apparatus for processing telephone calls is connected between a primary rate ISDN (PRI) telephone line and a host computer. Telephone call data is transferred between the host computer and remote analog, basic rate ISDN (BRI) and/or PRI remote sites. The apparatus includes a digital signal processor that can run multiple signal processing sessions simultaneously and a control processor that can run multiple control processing sessions simultaneously. The apparatus can therefore process multiple telephone calls of one or more types simultaneously.
