  • Patent number: 9592500
    Abstract: Among other things, in general, a two-stage filtration and extraction assembly is described, as well as methods of use thereof.
    Type: Grant

  • Patent number: 9240995
    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.

  • Patent number: 8332911
    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 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.

  • Patent number: 7480237
    Abstract: 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.

  • Publication number: 20070064593
    Abstract: A Cable Access Module is periodically monitored to detect lock-up condition on an upstream channel. Traffic activity on an upstream channel of the CAM is compared to predetermined criteria to determine lock-up. If CMs are detected being coupled to the CAM, a PING message is sent to a group of CMs. If the PING is not acknowledged, a round robin counter is used to cycle through modems sending PINGs thereto. If no PINGs are acknowledged, the CAM is deemed satisfactory if upstream bytes over the upstream channel are detected. If not, an escalating maintenance subroutine implements corrective action of increasing magnitude during based on a recovery count variable that increments with each successive pass before returning to the monitor period parent routine. If CMs were detected as coupled to the CAM, but some data has been passed over the upstream channel being evaluated, the escalating maintenance subroutine is invoked.

  • Publication number: 20010044845
    Abstract: Cable data service levels can be upgraded or downgrade automatically, on a subscriber's request, by using the unique identifier preprogrammed into industry-standard-compliant cable modems. A processor adjunct to the CMTS in a cable data system receives and processes service level change requests. Requests that are granted are sent back to the CMTS for subsequent execution. Faster internet access can be provided on a customer's own initiation.
