Abstract
Abstract In advanced digital networks for providing selective point-to-point communications between subscribers terminals and broadband server equipment operated by a plurality of independent information service providers, routing through the network is controlled by functionality identified as a Level 1 Gateway. In an enhanced video dial tone network additionally providing an array of broadcast services from multiple providers, the Level 1 Gateway also provides high level control over at least some of the broadcast services. The Level 1 Gateway will perform a variety of functions including communications port management of transmissions of information between subscribers and servers, processing of billing information and session management. The Level 1 Gateway generates menus of providers and broadcast services, either as a function of providers and services available through a particular portion of the network or in a customized fashion specified by individual subscribers. The Level 1 Gateway may also provide a PIN number functionality, e.g. to permit parents to limit which providers and broadcast services that their children can access. The Level 1 Gateway is itself an interactive device in that subscribers can input information and receive display information from the Gateway to define or modify their own video dial tone service through the network.
