Abstract:
1. A cable modem termination system for associating a plurality of upstream channels with a plurality of downstream channels, all of said upstream channels and downstream channels operating on a communications device, comprising: (a) a media access controller, including: a filter for receiving a bandwidth allocation message from a first communication device or a second communication device, wherein said filter processes authorization instructions to authenticate said bandwidth allocation message based on information in a register, wherein said filter includes a primary filter for receiving a bandwidth allocation message produced by the first communications device, and a secondary filter for receiving a bandwidth allocation message from the second communications device, wherein the second communications device is linked to the first communications device over a slave interface; and a parse processor for formatting said bandwidth allocation message for a designated upstream channel in response to said bandwidth allocation message being authenticated; (b) a bandwidth allocation memory for selecting and/or storing said bandwidth allocation message from said parse processor; and (c) at least one upstream signal receiver, wherein said bandwidth allocation memory is operable to forward said bandwidth allocation message to the upstream signal receiver that is operable to utilize said bandwidth allocation message to anticipate the arrival of an upstream signal.
