Level 1 gateway for video dial tone networks

摘要

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. 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, either as a function of providers available through a particular portion of the network or in a customized fashion specified by individual subscribes. The Level 1 Gateway may also provide a PIN number functionality, e.g. to permit parents to limit which providers 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.
