Distributed and highly software reconfigurable CMTS (CMRTS) device, based on MAC and PHY units with FPGA and DSP components, for a HFC CATV network. The various CATV RF modulators, such as QAM modulators, may be divided between QAM modulators located at the cable plant, and remote QAM modulators ideally located at the fiber nodes. A basic set of CATV QAM data waveforms may optionally be transmitted to the nodes using a first fiber, and a second set of IP/on-demand data may be transmitted to the nodes using an alternate fiber or alternate fiber frequency, and optionally using other protocols such as Ethernet protocols. The nodes will extract the data specific to each neighborhood and inject this data into unused QAM channels, thus achieving improved data transmission rates through finer granularity. A computerized “virtual shelf” control system for managing and reconfiguring the FPGA and DSP based CMTRS units is also disclosed.

An integrated network receiver includes a first universal resource identifier for a first channel and an input suitable for receiving a first input video content from the Internet based upon the first universal resource identifier. The integrated network receiver provides the first input video content for the first channel to a head end connected to a plurality of customer devices through a transmission network. The integrated network receiver updating the first universal resource identifier based upon data obtained from a video address server.

Premises apparatus and methods for providing aggregated high-bandwidth, low-latency, data service over a content delivery network including existing wireline infrastructure. In one embodiment, a network architecture having service delivery over at least portions of extant hybrid fiber coax (HFC) infrastructure is disclosed, which includes standards-compliant ultra-low latency and high data rate services (e.g., 3GPP and IEEE Std. 802.11 services) via a common service provider. In one variant, an expanded frequency band (e.g., 1.6 GHz in total bandwidth) is used over the coaxial portions of the HFC infrastructure, which is allocated to two or more sub-bands. Premises apparatus are used to support multi-service integration (e.g., aggregation of mobile wireless, premises, and other services), as well as incipient IoT applications and technologies.

Methods and apparatus for enhancing connectivity for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced connection of user devices serviced by the base station (such as 3GPP UE or CBRS FWA) to a core entity for e.g., authentication and packet session establishment. In one implementation, enhanced Cable Termination System (CMTS) and cable modem (CM) devices coordinate to allocate prioritized service flows to traffic sourced from the base station. These service flows can selectively bypass extant DOCSIS protocols which might otherwise increase connection latency (including connection failure) such as AQM (active queue management) and packet dropping algorithms. In some variants, upstream service flow data rates can also be enhanced through temporary utilization of higher-order modulation and/or coding schemes.

The processing circuitry/means is configured to determine information on a power level of received transmissions at a plurality of points in time in a plurality of frequency bands of an upstream spectrum via the transceiver circuitry, to determine, for each of the plurality of frequency bands, numeric information on an occurrence of one or more power levels of the received transmissions in the respective frequency band, and aggregate the numeric information on the occurrence of the one or more power levels of the received transmissions by frequency band.

Systems and methods for dynamically adjusting a MAP advance time for a MAP message sent from a CCAP core to an RPD, the MAP message allocating bandwidth for the RPD during an interval beginning at a start time specified in the MAP message.

A network test instrument is operable to conduct sweep tests with a cable modem termination system having a distributed architecture. Through signaling performed via a telemetry channel between the network test instrument and a sweep server, the network test instrument can initiate the sweep test. The sweep server communicates with the cable modem termination system to facilitate the sweep test between the network test instrument and the cable modem termination system.

A novel method of operating a Distributed Cable Modem Termination System is provided. Each branch CMTS node in a distributed CMTS supports a complete CMTS system and with full-spectrum ports. One or more MAC domains are defined at each branch CMTS node. A MAC domain defined at a branch CMTS node includes only service flows of the CMs that are connected to the branch CMTS node. Identifiers of service flows coming from a branch CMTS node are always unique, i.e., two different service flows of the branch CMTS would always have different SIDs, even if they belong to different MAC domains. On the other hand, service flows belonging to different branch CMTS nodes are free to reuse the same identifiers.

Communications are performed between the network controller and the endpoint device through a wired communication medium using the upstream and downstream channels. The first subset and second subsets of the plurality of channels are designated as upstream channels and downstream channels, respectively, based at least in part on one or both of upstream and downstream channel demand and channel availability.
