Abstract

A system for validating two-way continuity of a customer premises equipment (CPE) unit in a hybrid fiber coax (HFC) cable network. A two-way client uses a two-way query interface to acquire information indicative of the two-way operational status of a subscriber CPE units from a two-way validation server and to display the information graphically.
