A device, such as a cable modem or embedded media terminal adaptor that attempts to obtain unauthorized network services, is designated by head end equipment, such as a CMTS, as being a 'rogue' device. Upon a range request from the rogue device, the CMTS responds with a continuing range command. Upon receiving each periodic range request transmitted from the rogue device during a periodic station maintenance opportunity, the CMTS responds with another continuing range command. Thus, the rogue device does not ever establish connection with the CMTS because an ACK message is not received back from the CMTS.

Method and system for denying cable modem access to a broadband network

A device, such as a cable modem or embedded media terminal adaptor that attempts to obtain unauthorized network services, is designated by head end equipment, such as a CMTS, as being a 'rogue' device. Upon an initial range request from the rogue device, the CMTS responds with a continuing range command. Upon receiving each periodic range request transmitted from the rogue device during a periodic station maintenance opportunity, the CMTS responds with another continuing range command. Thus, the rogue device does not ever establish connection with the CMTS because an ACK message is not received back from the CMTS. Moreover, use of CMTS resources for processing request from rogue devices is minimized because the rogue device does not reinitialize its MAC after a predetermined period of time, which it would do if a periodic ranging opportunity was not scheduled.

Static balancing of cable modems across upstream channels is made based on the channel's current bandwidth demand compared to a first and/or second CAC threshold level. If both threshold levels are exceeded, the modem is assigned to the channel having the lowest bandwidth demand. After registration, predictive balancing modems according to whether an MTA is part of a given modem avoids concentration of modems having MTAs on certain channels while other channels serve only moderns without MTAs. Modems are also predictively balanced according to whether they have associated a DSA_use_history profile. Modems associated with certain subscribers may be balanced according to the time of day balancing is occurring based on the profile. Thus, light users during working hours may be balanced as heavy users at night if they typically download video content or use VoIP features during the evening.
