Abstract
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.
