1. A broadband intelligent network comprising:

  • a fast-packet switch having a plurality of ports;

    a switch processor to establish switched virtual connections or permanent virtual connections between ports;

    respective customer links having a broad digital bandwidth connected to predetermined customer switch ports for transporting signaling and data cells to and from respective customer premises equipment (CPE) units;

    a network control processing system interfaced to at least one switch port to receive signaling cells generated by CPE units and carrying customer service request data, and to control network responses thereto;

    a resource system for the network having at least one resource unit interfaced to a resource unit port of the fast-packet switch to receive query cells and to transmit response cells carrying resource data;

    the switch processor detecting each customer generated signaling cell generated by a CPE unit and received by the switch and routing each generated signaling cell through a first virtual circuit and the one switch port to the network control processing system;

    the network control processing system detecting service request data in each signaling cell requesting download of a program module or data from the network to a CPE unit from which the service request data is received or from the requesting CPE unit to the network;

    the network control processing system responding to download requests by effecting the requested download between the requesting CPE unit and the network through the fast-packet switch; and

    the network control processing system directing the switch processor to establish a second virtual circuit in the fast-packet switch between the requesting CPE unit and the resource unit if a host or other resource unit connection is required by the service request.
