Abstract

A broadband intelligent network employs a fast-packet switch having a plurality of ports and a switch processor for establishing switched or permanent virtual port connections, for routing cells through the connections to and from the ports, and for processing network operations signals. A network control system is coupled to the switch processor to receive network operations signals therefrom and to send network operations signals thereto. A network operations system is interfaced with the network control system which routes network operations signals between the switch processor and the network operations system. The operations system may be a family of operations systems which provide respective network support functions including administration, maintenance, provisioning and billing functions.
