Abstract
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.
