Abstract: Systems and methods for source address verification and/or retention for access devices.

Abstract: A Data Over Cable Interface Specification (DOCSIS) node includes a first DOCSIS port and a second DOCSIS port. The node also includes a plurality of radio frequency (RF) ports. A plurality of client devices can be coupled to the RF ports. A RF switching network is coupled between the first DOCSIS port and the second DOCSIS port, and the plurality of RF ports. One or more control circuits can switch the RF switching network between at least a first state and a second state. The switching of the RF switching network allows the one or more control circuits to identify which client devices are coupled to which RF ports of the node.

Abstract: A cable distribution system includes a head end connected to a plurality of customer devices through a transmission network that includes a first remote physical device, where the first remote physical device includes remote physical layer processing, that converts digital data to analog data suitable for the plurality of customer devices, where the head end includes at least one server each of which includes a respective processor.

Abstract: Methods, systems, and computer readable media can be operable to facilitate the provisioning of a device using an embedded cable modem media access control (MAC) address. An optical network unit (ONU) may include an embedded cable modem, wherein the embedded cable modem has a dedicated MAC address. Provisioning servers may provide identical configuration files to a virtual cable modem at an optical line termination (OLT) and the embedded cable modem at the ONU. The embedded cable modem MAC address, along with an associated Internet protocol (IP) stack, enables traditional DOCSIS cable modem provisioning and management over a passive optical network.

Abstract: Systems and methods can operate to improve the communication bandwidth in communication systems. Communication systems can use new forward error correction (FEC) algorithms to increase communication bandwidth. New FEC algorithms can also enable the use of other modulation formats to further improve communication bandwidth. Communication devices that can select from a plurality of FEC algorithms and modulation formats can maintain backward compatibility with the deployed FEC algorithms and modulation formats implemented in legacy communication devices while realizing increased communication bandwidth.
