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 system to eliminate problems due to skew between the transmission clocks of the various components. This aspect of the present invention allows the transmission of the data to be delayed by at least one frame length and then uses the clock rate of the destination component to ensure that clock skew is eliminated.
