Abstract:
1. A call data and hardware cache for improving the performance of a dial-up access concentrator, which comprises a shelf controller, a plurality of signal processor cards and a plurality of line cards, by caching the call data created for a call connection for use in the next successively received incoming call, comprising: cache memory means for storing communication connection data, including hardware device setup and the communication connection data created for a call connection, that serves to interconnect an incoming call connection that appears on a one of said plurality of line cards with a one of said plurality of signal processor cards; means for detecting conclusion of a call connection on said one of said plurality of line cards; means, responsive to said call conclusion, for aborting deconstruction of the existing call connection; means for maintaining physical hardware connections that interconnect said one line card to said one signal processor card, the associated call processing and call connection resources, and the associated said communication connection data in said cache memory means; means, responsive to receipt of a successive incoming call connection on said one line card, for determining whether said physical hardware connection and associated stored communication connection data can be used to serve said successive incoming call connection.
