20080232801 | METHOD AND SYSTEM FOR TRANSPORTING DOCSIS COMMUNICATION SIGNALS OVER A PASSIVE OPTICAL NETWORK - A translation agent adapts DOCSIS information, primarily QoS information, for transmission over a PON. The agent places into an IP address field of a DHCP message the MAC address of an ONU associated with a CPE device attempting to register with a CMTS. The translation agent intercepts DHCP reply messages from the DHCP server using the MAC address of the ONU. The translation agent extracts information, including an IP address of the client CPE assigned by the DHCP server. The agent downloads a configuration file for the CPE device using the configuration filename and configuration file server contained in a DHCP reply message. Information contained in the configuration file is converted from content in a format used by DOCSIS, to content in a format used by PON devices. The translated content includes QoS parameters, functions related to which are controlled at the ONU by an OLT coupled to the CMTS. | 09-25-2008 |
20100317387 | Providing Flexible RF Channel to Port Mappings - Methods, systems, and apparatus can be used to flexibly allocate RF channels to output ports on edge termination systems. Flexible edge termination systems can include multiplexing modules operable to combine signals together inside of the flexible edge termination system to provide a flexible mapping of RF channels to output ports. | 12-16-2010 |
20110096819 | ESTIMATING SYSTEM AND TRAFFIC DATA IN A DOCSIS SYSTEM - Methods for computing system data (e.g., the number of CMs per DS-SG or US-SG) and traffic data (e.g., the number of online CMs, the number of active CMs, the percentage of time a CM is online, the percentage of time a CM is active, and the concurrency of CMs) in a DOCSIS system are disclosed. | 04-28-2011 |
20110235285 | INTERFACE PORT CONFIGURATION TO REDUCE CONNECTION INTERFERENCE - Methods and apparatuses for reducing connection interference within and across adjacent interfaces are provided. An interface includes ports arranged along at least a first axis and second axis. The ports on the first axis are offset from the ports on the second axis. When two interfaces are provided adjacent to each other, the ports on the last axis of the first circuit board are offset from the ports on the first axis of the second circuit board. | 09-29-2011 |
20130090110 | MANAGING BATTERY POWER USAGE OF A LOST MOBILE DEVICE TO EXTEND SEARCH TIME FOR THE LOST MOBILE DEVICE - Methods and apparatuses are provided to use energy reduction techniques in an effort to extend the battery life of a mobile device when the mobile device is lost to increase the time an owner of a lost mobile device has to search for the lost device using any lost mobile device locating technique before the mobile device's battery fully discharges. A lost mobile device receives a power preservation command and operates in a power preservation mode while executing a locating technique to aid in the locating the lost mobile device. | 04-11-2013 |

20090262644 | INTELLIGENT TRAFFIC OPTIMIZER - Bandwidth is assigned to subscribers of a data network by applying logic of one or more network devices to sample bits of information communicated over a network communication medium to identify if there is a network congestion condition or an extremely lightly loaded condition. The maximum bandwidth assigned to a subscriber is below a normative maximum bandwidth assigned to the subscriber if the network is congested and the logic of the one or more network devices identifies the subscriber as a heavy bandwidth user. The maximum bandwidth assigned to a subscriber is above the normative maximum bandwidth if the network is extremely lightly loaded and the subscriber is a heavy bandwidth user. | 10-22-2009 |
20090274156 | CARRIER ETHERNET OVER DOCSIS - A network includes a provider edge device with logic to encapsulate Ethernet frames received from customer equipment into Data Over Cable Service Interface Specification (DOCSIS) frames using Layer Two Tunneling Protocol. The provider edge device further includes logic to implement a virtual switch instance (VSI). | 11-05-2009 |
20090285233 | MULTI-SERVICE PHY BOX - A data communication system includes multiple Media Access Control (MAC) units, multiple physical layer (PHY) interface units, and logic to communicate between the MAC units and the PHY units using a single tunneling protocol over Internet Protocol (IP). | 11-19-2009 |
20100005500 | METHOD FOR SIMULTANEOUSLY MANAGING HIGH-SPEED DATA AND VIDEO STREAMS IN A SINGLE MAC PROCESSING ENVIRONMENT - A packet data flow processor applies a first level of Data Over Cable Service Interface Specification (DOCSIS) processing to packet flows that are not from trusted sources, and applies a second level of DOCSIS processing, simpler than the first level, to packet flows from the trusted sources. | 01-07-2010 |
20100183021 | Method and Apparatus for Queuing Data Flows - In a data system, such as a cable modem termination system, different-priority flows are scheduled to be routed to their logical destinations by factoring both the priority level and the time spent in queue. The time that each packet of each flow spends waiting for transmission is normalized such that the waiting times of all flows are equalized with respect to each other. A latency scaling parameter is calculated. | 07-22-2010 |
20110161510 | Method and system for layer-3 subscriber login in a cable data network - A subscriber login server is used for managing a subscriber login session. The login server is associated with a DHCP server for configuring a premise equipment device and operator-managed device. A subscriber login client at the premise equipment device securely communicates login username and password identifiers to the subscriber login server without using PPP technology. The login server retrieves matching identifiers from a RADIUS server and authorizes service with messages to the DHCP server and the CMTS. | 06-30-2011 |

20080285592 | Extended layer two tunneling protocol applications and architectures - A device, deployed at the edge of a provider network, includes logic to receive traffic from one or more customer edge devices, and to encapsulate the customer traffic into a Layer 2 tunnel of an IP frame. The IP frame in further included within an Ethernet frame, and quality of service priority bits are promoted from the customer traffic into both the IP frame and the Ethernet frame. | 11-20-2008 |
20090034509 | METHOD AND SYSTEM FOR REDUCING UPSTREAM NOISE IN A NETWORK USING AN ACTIVE MULTIPLEXER - An active multiplexer contains a switching mechanism that connects one of a plurality of upstream links from corresponding nodes in a communication network to an upstream output based on information contained in a MAP. The MAP contains scheduling information of the next user stations, which are coupled to the nodes, and which are scheduled to transmit in the upstream direction during a period following the current time. Station identifiers are associated with their corresponding node identifier during a ranging burst interval into a station/node table, which is used in conjunction with the MAP to control the active multiplexer. Based on the MAP, the active multiplexer connects the node, as determined from the station/node table, that serves the station that is scheduled to transmit upstream traffic and disconnects other nodes. | 02-05-2009 |
20090113503 | METHOD AND SYSTEM FOR ALLOCATING BANDWIDTH BASED ON TRANSMISSION POWER OF DEVICES TRANSMITTING OVER COMMUNICATION CHANNELS IN A NETWORK - A method performed by a central network device, such as a network edge device, or a CMTS, determines whether some of a plurality of user devices coupled to a communication device are transmitting at substantially their respective maximum power output level over a given channel. If the central device determines that some of the devices are operating at near their maximum output level (“power pegged,) the central device searches for another channel that can carry the traffic of the power pegged devices at reduced data rate. If another channel can accommodate transmission of signals of the power pegged device, the central device instructs the power pegged devices to tune to the new channel at a reduced data rate compared to the data rate of the current channel. | 04-30-2009 |
