Disclosed are call processing methods which are performed by a network terminator located at a subscriber's premise. The network terminator is coupled to a digital network and a communication device at the subscriber's premise and can perform call waiting, caller identification, call conferencing without intervention from a telco's switching system that requires an additional charge to the subscriber for these services. In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the network terminator of the present invention.

Methods for performing intelligent network services with an ISDN network terminator located at a subscriber's premise

A communication system ( ) includes at least one digital signal processor (DSP) and a WAN driver ( ) operating on a processor that is electrically coupled to a memory. The WAN driver ( ) receives task allocation requests from a host to open/close communication channels that are handled by the at least one DSP. Each task is allocated to one of the at least one DSP according to a total current task processing load for each of the at least one DSP, a maximum processing capability for each of the at least one DSP, and a processing requirement for each task being allocated to the one of the at least one DSP that can handle the additional processing load of the task being allocated.

A configuration controller ( ) keeps track of the MIPs processing requirement of each task available for allocation across the plurality of DSPs and the maximum processing capability of each DSP of the plurality of DSPs in response to changes in configuration of the communication system ( ).

Adaptive method and apparatus for allocation of DSP resources in a communication system

A communications adapter card provides an interface for a TI or E1 transmission line and a signal processing circuit which can be programmed to process receive and transmit data in either an ISDN or an ATM format. Preferably, two such interfaces and two such signal processing circuits are provided on the card, so that a single adapter card can be used for attachment to both an ISDN network and to an ATM network. Each signal processing circuit includes a pair of DSPs, each of which has a two port buffer extending to a parallel bus. All such DSPs are connected to a data bus. The DSPs in each signal processing circuit execute programs to operate in either an ATM mode or an ISDN mode.
