Abstract

A Broadband Intelligent Network employs an ATM fast-packet switch to route signaling cells from a calling party to a switch port directly connected to a network controller. The signaling cells carry a service request for download of a program module or data from a network resource unit to the calling party, or for download of a program module or data from the calling party apparatus to a network host resource unit, or for service circuit service to the calling party or in a connection path between the calling party and a called party, or for a message broadcast. The network controller responds to the information in the signaling cells and establishes the necessary switched virtual connections in the ATM switch to provide the requested services. A service creation program may be downloaded to the customer from the network, and used by the customer to create a new service script which is subsequently downloaded to the network for execution.

the virtual circuits further include direct connection paths between the predetermined resource unit and each of the requesting and second and third CPE units.

78. A method for operating a broadband intelligent network having a fast-packet switch with a plurality of ports, a switch processor to establish switched virtual connections or permanent virtual connections between ports, respective customer links having a relatively 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, and wherein the steps of the method comprise:

detecting each signaling cell generated by a requesting CPE unit and received by the fast-packet switch; and

routing each such signaling cell through a first associated virtual circuit and the one switch port to the network control processing system;

detecting service request data in each signaling cell requesting a conference call involving the requesting CPE unit and at least second and third CPE units; and

directing the switch processor to establish additional virtual circuits through the fast-packet switch among the requesting and second and third CPE units.
