Telecommunication switch with programmable communications services

A programmable communications switch comprising:

• controllable-switching means for dynamically connecting or disconnecting communication paths between various ones of a plurality of ports in response to messages generated by a host, including a time slot interchange for switching a plurality of time slots corresponding to said ports and means for processing said messages;
• one or more means connected in communicating relationship with said switching means for terminating either analog or digital lines or trunks which represent said ports, said communicating relationship including a bus for carrying time division multiplex TDM data;
• and
• one or more programmable means connected in communicating relationship with said switching means and said one or more terminating means for providing programmable communications services to said ports in response to messages generated by said processing means, one or more of said programmable means including one or more digital signal processing means for providing said communications services to said ports, each of said programmable means being operable to receive TDM data via said data bus from said terminating means during all of said time slots and to transmit TDM data via said data bus to said terminating means during preselected ones of said time slots, whereby said communications services are provided without switching the TDM data received or transmitted by the programmable means through said time slot interchange.
