| 20100254283 | CMTS PLANT TOPOLOGY FAULT MANAGEMENT - A cable television plant may include fiber nodes, cable modems, a management information base (MIB), and a cable modem termination system (CMTS). The CMTS may include logic to apply information from the MIB to determine the suitability of resources assigned to the fiber nodes from particular MAC domains for providing data communications. | 10-07-2010 |
| 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 |
| 20090290879 | WAVELENGTH DISTRIBUTION FOR OPTICAL TRANSPORT - An optical communication system includes logic to communicate using optical channels set outside a fiber zero dispersion zone, and having channel spacing that decreases with increasing distance from the fiber zero dispersion zone. | 11-26-2009 |
| 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 |
| 20090282134 | AUTOMATED DOUBLE FIRMWARE UPGRADE - A method of upgrading the software load of a device includes receiving a configuration file and checking if a device software load matches load information (EE) of the configuration file. If the device software load does not match the EE of the configuration file, a check is made to determine if the device software load matches new load information (NE) of the configuration file. | 11-12-2009 |
| 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 |
| 20090263141 | DUAL USE OF TEST POINT POWER MONITOR - A channel alignment system in an optical communication network includes logic to sample power of a quadrature amplitude modulation (QAM) channel at a component downstream from a QAM modulator. The system determines if the sampled channel power has a sufficient level. The system signals power control logic of the QAM modulator to adjust a gain of the sampled channel. | 10-22-2009 |
| 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 |
| 20090256655 | Anti-Parallel Pi Pin Attenuator Structure with Improved CSO Performance - An RF attenuator circuit includes an anti-parallel PI structure having an input shunt arm comprising a single PIN diode, and an output shunt arm comprising a single PIN diode configured to have opposite polarity of the PIN diode of the input shunt arm. | 10-15-2009 |
| 20090237767 | PREDISTORTION USING FPGA - Predistortion logic for an optical communications laser or optical modulator, includes predistortion logic embodied in a field programmable gate array (FPGA). A first analog to digital converter (ADC) provides a representation of an RF signal at an input of the FPGA. A digital to analog converter provides a representation of an output of the FPGA to a laser or modulator. | 09-24-2009 |
| 20090237285 | DIGITAL TO ANALOG CONVERTER SPUR CANCELLATION - A device includes an upsampling digital-analog converter (DAC) and logic to add a DC offset to a signal input to the DAC, the logic adapted to set the DC signal to cancel a DAC output spur. | 09-24-2009 |
| 20090046442 | FORMED SHIELDING FEATURE - An metal housing comprising an electrical device includes electrical pins that protrude from the metal housing, and the metal housing formed with a compressible protrusion around the pins. | 02-19-2009 |
| 20090040924 | METHOD AND SYSTEM FOR MOVING DISTINCTIVE TRAFFIC FLOWS TO A DIFFERENT PRIORITY SERVICE FLOW - A cable modem termination system (CMTS) is adapted to move particular traffic flows to a different priority service flow. The CMTS includes detection logic, or is coupled to detection logic, to detect the presence of particular traffic, logic to establish a different priority service flow between a cable modem termination system and a cable modem, and flow control logic to direct a given packet on to the different priority service flow if the given packet contains information that matches one or more classifiers. | 02-12-2009 |
| 20080285597 | SYNCHRONIZING SEPARATED EDGE QAM DEVICES LOCATED REMOTELY FROM A CMTS - The clocks of one or more edgeQAM devices are synchronized with a master clock at the remotely located CMTS. A master clock signal may be transmitted via a dedicated gigabit Ethernet link. Alternatively, master clock information contained in a time synchronization message may be transmitted for use in adjusting local oscillators that drive local clocks at respective edgeQAM devices. | 11-20-2008 |
| 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 |
