  • Publication number: 20200358684
    Abstract: A method receives error measurements from network elements. Groups of network elements are generated based on similarity of error measurements and a bitloading profile for each of the groups of network elements is generated based on the error measurements for each respective group. Each bitloading profile includes a modulation level determined to be sufficient for transporting content to respective groups of network elements. The method then assigns a set of bitloading profiles to each network element based on the groups of network elements and the bitloading profile generated for each of the groups. The bitloading profile for each of the groups of network elements and the assigned set of bitloading profiles are output to a network device. The network device uses the bitloading profiles to modulate content sent to respective customer premise equipment.

  • Patent number: 10128950
    Abstract: A bi-directional coupler assembly includes a first port for connecting to one of an input forward path RF signal line and an output forward path RF signal line. A second port connects to the other of the input forward path RF signal line and the output forward path RF signal line. A relay is connected between the ports and to at least one directional coupler. In a first state of the relay, an input forward path RF signal delivered from the input forward path RF signal line and through the first port is directed through the at least one directional coupler in a first direction. In a second state of the relay, an input forward path RF signal delivered from the input forward path RF signal line and through the second port is directed through the at least one directional coupler in said first direction.

  • Patent number: 10122544
    Abstract: Particular embodiments provide an N+0 sharing scheme for networks. The N+0 sharing scheme includes no dedicated spare among a group of active elements. Each active element may provide service to a medium, which may be associated with a medium. When a failure to one of the active elements occurs, at least one of the working active elements takes the workload of the failed active element. The cost of N+0 sharing is a reduced per medium (e.g., service group) capacity during a failure. That is, some service groups may receive less bandwidth from the active element that is used in the sharing scheme to compensate for the failure. However, this may be preferable to service operators compared to the additional cost of including a spare for the group of active elements, or the complete loss of service that occurs when a failure occurs without a failure recovery scheme.

  • Patent number: 10003403
    Abstract: Systems and methods can operate to detect and avoid optical beat interference (OBI) in broadband devices by use of restrictive channel assignment. An OBI-mitigating mapper algorithm can leash OBI candidates in a circular queue to avoid scheduling service flows likely to result in OBI generation. In some implementations, the algorithm can automatically leash all pre-DOCSIS 3.0 service flows. In alternative implementations, the algorithm can allow the CMTS to normally load balance pre-DOCSIS 3.0 devices while manually adding and/or removing pre-DOCSIS 3.0 service flows from the OBI candidate queue based upon lost transmissions or a designated age-out timer.

  • Patent number: 9960840
    Abstract: An optical line terminal is operable in a passive optical network. The optical line terminal includes a chassis. A plurality of optical subsystems are disposed within the chassis. Each optical subsystem is operable to generate optical signals for delivery to a port. Each optical subsystem includes one or more optical switches. When a fault condition is detected at a first optical subsystem preventing the delivery of first optical signals generated by the first optical subsystem to the port of the first optical subsystem, the optical switches switch to deliver second downstream optical signals generated by a second optical subsystem to the port of the first optical subsystem.

  • Patent number: 9736511
    Abstract: Particular embodiments use a network device, such as a gateway, as an interface between a first network, such as a hybrid fiber coax (HFC) network, and a second network, such as a home network. The first network includes a frequency spectrum that may be considered “high split”, and the second network has a frequency split that is used by legacy set-top box boxes. A head-end sends a network downstream signal that includes the out of band downstream signal in the downstream frequency band using the HFC network's frequency split. The out of band downstream signal may be represented by digital data. The gateway can then determine samples from the digital data, which are then used to reproduce the out of band downstream signal at the desired frequency for the home network. That is, the out of band downstream signal may be recreated in the frequency range of 70-130 MHz.

  • Patent number: 9699102
    Abstract: A system for increasing bandwidth to a communication device, comprising: a packet scheduler; and a transmitter; the system configured to operate the packet scheduler to schedule packets of a service flow onto multiple media access control (MAC) channels forming a MAC channel group before operating the transmitter to send the scheduled packets from an origination device toward a destination device, the packet scheduler waiting a maximum group cross channel skew time for an out-of sequence packet, the maximum group cross channel skew time a maximum of multiple pair cross channel skew times, one pair cross channel skew time associated with each pair grouping of MAC channels configured to be formed from the MAC channel group; and the system configured with a setting to allow only a single channel of the multiple channels of the MAC channel group to carry DOCSIS messages, and to override the setting to share at least some of the channels of the MAC channel group among multiple cable modems while the MAC channel gr

  • Patent number: 9641460
    Abstract: Particular embodiments provide systems and methods to reduce the average power consumption per subscriber. Particular embodiments select windows of time when network components are under-utilized by subscribers of the network. During periods of under-utilization of a network component, subscribers may be consolidated onto a smaller number of network components by increasing the service group size. The consolidation increases the service group size, which has the effect of lowering bandwidth per subscriber. However, the bandwidth use per subscriber may be lower during this time. The use of the smaller number of network components allows the energy for these components to be used more efficiently. When the subscriber network demands increase, the distribution system places the network components into an active power state and redistributes the subscribers to the newly-activated components. This decreases the service group size, such as back to the original size.

  • Patent number: 9596240
    Abstract: 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. The login client can emulate a PPP login client so that a user's interface is similar to a PPPoE client. However, a layer-3 CMTS can be used instead of a layer-2 CMTS. In addition, subscriber authentication and accounting using RADIUS are preserved, positive network access control at the CMTS is maintained, and native IP traffic is routed or switched for maximum performance and QoS treatment.
