ABSTRACT:
An adjunct processor (100) is embedded in a telecommunications switching system (10) wherein port circuits (106-108) are interconnected with each other and with a control processor (101) by a TDM bus (105). The adjunct processor is physically incorporated into the switching system, is connected directly to the TDM bus, and communicates with the control processor exclusively via the TDM bus. The adjunct processor is made up of a telecommunications feature module such as a conventional voice-mail system (200), an arrangement (210, 220, 240) for interfacing the feature module to the TDM bus whereby the adjunct processor emulates a port circuit in its connection to the TDM bus, and an arrangement (203) for interfacing the feature module to the control processor whereby the adjunct processor emulates a telephone in its interactions with the control processor.
