| 摘要 |
A broadband communication system (FIG. 1) having a reverse path over which reverse, upstream signals are transmitted and forward path over which forward, downstream signals are transmitted includes a requesting device (345) for generating and transmitting a downstream digital optical signal comprising a status request and information. The system also includes a responding device (410) coupled to the requesting device (345) for receiving the downstream digital optical signal and decoding the status request therefrom. The responding device (410) also processes the status request in its digital format and gathers digital inputs indicative of requested statuses. Then, the responding device (410) transmits an upstream digital optical signal, comprising at least status information indicative of the requested statuses, to the requesting device (345) over an optical communication channel.
