An architecture for providing interactive broadband products and services uses existing cable and telephone plant. The architecture includes a central office switch in communication with a head-end server and a Customer Premises Equipment (CPE) device such as, for example, a modem emulator, data terminal, set-top terminal or personal computer. The CPE device is provided in communication with the head-end server via cable plant for downstream broadcasts and is further provided in communication with a central office switch via telephone plant for upstream signaling and downstream control messages.

A method and system for determining the required number of active video circuits in an interactive video delivery network required to meet the specified blocking probability constraints. By determining peak loading hours as well as the number of system subscribers in a given video delivery network, the user may determine the blocking probability of the interactive video delivery system in accordance with the formula: ##EQU1## This information may thereafter be used to determine the number active video circuits to meet the determined blocking probability.
