Patent number: 10411830Abstract: A communication device (alternatively, device) includes a processor configured to support communications with other communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other communication device(s) and to generate and process signals for such communications. Such a communication device includes a processor configured to perform codeword builder functionality to generate information that undergoes error checking and correction (ECC) and/or forward error correction (FEC) coding. The processor intelligently selects packets from buffers to generate information blocks that undergo ECC and/or FEC coding and transmission and to meet certain latency constraints in conjunction with a predetermined period of time (e.g., a programmable threshold).Type: GrantFiled: January 31, 2016Date of Patent: September 10, 2019Assignee: AVAGO TECHNOLOGIES INTERNATIONAL SALES PTE. LIMITEDInventors: Niki Roberta Pantelias, Joel I. Danzig, Taruna Tjahjadi, Christopher John Plachta

Patent number: 9455785Abstract: Embodiments enable a network operator to use any (and a single) network management system (NMS) that it desires to manage a network having mixed fiber to the home optical network units (ONUs) and coaxial connected cable modems. For example, embodiments enable a cable company operator to use a DOCSIS (Data Over Cable Service Interface Specification) NMS (which the cable company already uses to manage its DOCSIS network) to manage such mixed network, by a simple addition of a DOCSIS Mediation Layer (DML) module between the NMS and the optical line terminal (OLT). On the other hand, embodiments enable a telephone company operator to use a standard EPON (Ethernet Passive Optical Network) OLT NMS with minor OLT and OAM (Operations, Administration, and Maintenance) protocol modifications to manage the same mixed network.Type: GrantFiled: February 13, 2015Date of Patent: September 27, 2016Assignee: Broadcom CorporationInventors: Edward Wayne Boyd, Ernie Bahm, Joel I.

Patent number: 9130878Abstract: Embodiments enable an Ethernet over Coaxial (EoC) Coaxial Media Converter (CMC) that implements only a subset of the functions (e.g., MAC and PHY) of a cable modem termination system (CMTS). The CMC sits between an optical line terminal (OLT) and a plurality of cable modems (CMs) that it serves. From the network management side at the OLT, the CMC appears and can be managed like an optical network unit (ONU). From the subscriber side, the CMC provides the same connectivity functions to the CMs as a CMTS and serves to terminate coaxial connections from the CMs.Type: GrantFiled: June 30, 2011Date of Patent: September 8, 2015Assignee: Broadcom CorporationInventors: Edward Wayne Boyd, Joel I.

Patent number: 7250887Abstract: A system for spur cancellation comprises an input, an output, a memory, and a summer. A value corresponding to an energy level of a spur is stored in the memory. The summer is configured to receive an input signal from the input, to receive the value from the memory, to subtract the value from the input signal, and to convey an output signal to the output. The output signal is a difference of the value subtracted from the input signal.Type: GrantFiled: October 25, 2005Date of Patent: July 31, 2007Assignee: Broadcom CorporationInventors: Joel I.
