Abstract
A switching system and a method for performing high-speed switching within a telecommunications system. One aspect of the present invention utilizes an internal host and a self learning routing algorithm to reduce the time required to identify an output channel for routing a communication. Thus, the overhead associated with querying an external database can be eliminated from the switching system allowing a switching system to reduce the call hold time, and thereby meet the call flow demands of the telecommunications system. Another aspect of the present invention is the use of a hashing algorithm in resolving routing decisions. The hashing algorithm operates on received DID numbers to identify an output channel for a received call. The hashing algorithm is able to accept any DID number as input. Therefore, this aspect of the present invention allows a switching system to quickly resolve routing decisions without requiring consecutive DID numbers. This aspect of the present invention also allows a switching system to perform true, ten digit portability of DID numbers. Another aspect of the present invention is buffering the data between various components of the telecommunications …
