Abstract: A network adapter (10) and wiring scheme makes use of existing plain old telephone service (POTS) wiring to provide support between analogue devices within the subscriber premise and an Integrated Digital Service Network (ISDN). Moreover, the network adapter and wiring scheme provides further support between digital devices within the premise and the ISDN while concurrently supporting analogue devices.

Abstract: In an communication system including a computer system comprising a digital signal processing adapter for performing a set of tasks, and a E-1 port for providing and receiving time division multiplexed (TDM) signals in accordance with a first inter-system communication protocol, such as the E-1 or T-1 protocols, a communication subsystem, for coupling to the IP system. The communication subsystem includes an E-1 link for coupling to the first I/O port, and for providing and receiving TDM signals in accordance with the E-1 or T-1 protocols. The subsystem further includes a digital signal processor adapter, coupled to the second I/O port, for enhancing processing capability of the digital signal processing resource; and a third I/O port, coupled to the digital signal processor circuit, for providing and receiving signals in accordance with the first or a second inter-system communication protocol.
