Abstract:
A communications services card for use in a telecommunications switch or a node of a telecommunications system, and said telecommunications switch including controllable switching means for dynamically connecting or disconnecting communications paths between various ones of a plurality of ports in response to messages generated by a host, including a time slot interchange (TSI) for switching a plurality of time slots corresponding to said ports and means for processing said messages, said controllable switching means being in communicating relationship with a TDM bus, one or more means for terminating either analog or digital lines or trunks which represent said ports and said means connected to said bus, and said bus having a first path for carrying information from said controllable switching means to said means for terminating and a second path for carrying information from said terminating means to said controllable switching means, the communications card comprising:a plurality of digital signal processing modules, each capable of processing data organized as inbound time slots and each receiving data by a time slot interchange (TSI) circuit with which it is paired and into which the received data is stored, the TSI circuits being disposed in parallel to one another, and in communicating relationship with said TDM bus, wherein the TSI circuits store the received data and each TSI circuit transmits a selectable amount of an outbound time slot, destined for any of said ports, of processed data; anda timing and control bus, connected in communicating relationship with each of the modules, for controlling the storing of the received data in the plurality of TSI circuits, and the transmission of data from the TSI circuits on to the TDM bus, whereby a predetermined amount of a time slot transmitted from a TSI circuit is placed in a portion of a time slot corresponding to the number of bits of said amount of said outbound time slot and destined for one of said plurality of ports, such that information is capable of being processed on a bit-by-bit basis.
