Abstract

An operational support system includes service creation, service activation and service control functions to provide on-line service activation for video information providers (VIPs) and video information users (VIUs) on a video dial tone network. The operational support system provides an open interface for VIPs to remotely provision network resources by remotely accessing and requesting changes in corresponding VIP profiles, stored in the operational support system, in order to add/delete VIP subscribers, update event schedules, and/or to download billing and usage statistics. The operational support system processes the remote request by verifying the request data with internal subscriber databases, comparing the request with available network inventory, and provisioning network resources by generating requests to network elements to establish the new service. The operational support system also is adapted to perform network creation functions including initial network configuration, logical assignment of network elements, initializing network element systems, assignment of work orders for physical interconnections, and performance verification of installed systems.
