Abstract

This telephone switching system is comprised of a plurality of time slot interchangers (TSIs) which exchange information on an interleaved basis. The TSI's write and read this information in their associated port data store memories using common buses on a time shared basis. The interleaving permits faster call processing since the data store operates faster than its associated TSI and can therefore respond to read/write requests from a number of TSI's. The interleaving also permits each TSI processor to serve only certain types of calls, wherein each TSI may be equipped with a specialized processor adapted to serve a unique type of call such as conference, nonconference, data, etc.
