Abstract
A bus connection controller in a voice processing is for managing the connection of a timeslot on a time-division multiplex (TDM) bus to a port on an adapter. The voice processing system includes basic time-division multiplex (TDM) connection management to enable the coordination of connections between resources such as channels on line cards (SPacks or VPacks), and channels on digital signal processor (DSPs) cards that provide, amongst others things, voice recognition, text-to-speech, fax capabilities and so on. Problems are encountered when a telephone call in a voice processing system ends suddenly because one of the callers hangs up. If the telephony channel has connections with other channels or resources via a TDM bus, callers may hear spurious data. To address this problem each call is associated with its corresponding connection on the TDM bus and each connection is associated with its connection details including the adapters and ports involved in connecting the calls. When one of the calls ends all the relevant ports involved with the connection are immediately disconnected.
