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. One of the problems with known voice processing systems having a TDM bus is that there is no facility to allow the use of third party devices without modifications being made to the TDM connection controller. The bus controller comprises: a custom server 42 for sending a first request including a port identifier and using a first protocol for connection or disconnection of a port indicated by said port identifer on an adapter to the TDM bus 26; a timeslot manager for analyzing the first request to determine the port availability and state and for making a second request; device driver means (48), corresponding to the particular adapter, for sending the appropriate signals …
