Abstract
A system (210) for facilitating bidirectional data transfer between a customer premises equipment (212) and information service providers (228A-N) includes a channel service unit (258) which receives packets of data from the information service providers (228A-N), and passes the packets of data to a router (256). The router (256) segregates the packets of data based on which customer premises equipment (212) is destined to receive the packets of data. An asynchronous transfer mode (ATM) adapter (264) converts the packets of data to an ATM cell, and an ATM modulator (266) synchronizes the ATM cell to facilitate transmission over an ATM broadband network (232). The particular packets of data provided by the information service providers are selected in response to a user request sent by the customer premises equipment (212) via the ATM broadband network (232) and transferred to the information service providers (228A-N) through the ATM modulator (266), the ATM adaptor (264), the router (256), and the channel service unit (258).
