The present disclosure relates to multi-MAC controller and single PHY systems and methods. An example method may include transmitting, via a first device in a Data Over Cable Service Interface Specification (DOCSIS) network, a first block of data within a first time slot and at a first power level, the first power level being based on an attenuation of a first network tap device associated with the first device. The example method may also include transmitting, via a second device in the DOCSIS network, a second block of data within the first time slot and at a second power level, the second power level being based on an attenuation of a second network tap device associated with the second device, the first power level being different than the second power level.

A method for signal leakage detection includes initializing a leakage probe by providing information about a tone to a plurality of nodes of a network, instructing a first modem connected to a first one of the nodes to generate the tone, instructing a set of the nodes to listen for the tone outside of the network according to the information about the tone, receiving, from the set of nodes, information about a plurality of detections of the tone outside of the network associated with a leakage of the tone from the network, and determining a location of the leakage of the tone from the network using the information about the detections of the tone.

A Cable Modem Termination System (CMTS) having a gateway configured to output signals on over data tunnels for transfer over a cable network to Customer Premises Equipment (CPE). Each data tunnel is preferably characterized as a one-way data stream of out-of-band (OOB) messaging signals.

A bandwidth allocation and monitoring method may divide available bandwidth on a shared communication medium into a plurality of discrete tones that can be individually allocated to modems on an as-needed basis. The effective modulation rate that a particular modem can use for each discrete tone can be monitored over time using a schedule of pilot tones transmitted from the modems on different tones at different times. The schedule may define representative pilot tones, in which case effective modulation rates for neighboring tones may be inferred from a determined effective modulation rate of a pilot tone.

Systems and methods for permitting DOCSIS 3.1 equipment to operate at higher frequencies than specified in the DOCSIS 3.1 standard. Exemplary systems may be capable of alternating between a first mode of operation that provides DOCSIS 3.1 compatible services and a second mode of operation providing a higher level of service than DOCSIS 3.1.

A communication device in a communication system in which functions that are converted to software are configured as a plurality of components, and the functions are realized as a result of the components being respectively executed by a plurality of communication devices that are connected to a network, the communication device including a sorting unit configured to acquire a signal that is transmitted by a first component and transmit the signal to a second component indicated by destination information that is added to the signal by the first component.

A method of proprietary TDMA (Time-Division Multiple Access) data modulated signals nonlinear signal splitting (switching) system is disclosed. Said TDMA system operates over distribution CATV infrastructure and in ES (extended spectrum) that is usually allocated above in the frequency band comparing to one defined in the CATV DOCSIS standard. Said system is meant to increase data throughput capacity over existing CATV based systems targeting primarily ES (Extended Spectrum band) by means of TDMA approach. The purpose of the RF switches based tap box is to connect specific device to which TDMA packet is relayed to. This approach reduces excessive losses that are present in standard tap boxes by disconnecting other devices, which are not receiving or sending related TDMA data packets. The described method introduces switch control receiver concept that allows for configuration of various operation modes such as regular switched TDMA, amplified and broadcast modes.

A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

Directional wireless drop systems are provided. These systems include a tap unit that is connected to a communications line of the broadband network; a cable modem unit connected to the tap unit; a plurality of wireless routers connected to the cable modem unit; and a directional antenna unit that is connected to at least a first of the wireless routers. Each wireless router is associated with a respective one of a plurality of subscriber premises that are served by the directional wireless drop system and is configured to communicate with at least one device that is located at the respective one of plurality of subscriber premises.

Disclosed herein are methods and systems for determining conditions for non-terminated service provider network connections. The method includes receiving, at a service provider headend, upstream signals from premises. An uncorrectable metric and a correctable metric are determined from a portion of the upstream signals upon application of signal correction to the upstream signals, where the portion is related to an operating frequency range of a networking device and an operating frequency range of Data Over Cable Service Interface Specification (DOCSIS) devices. An alert is generated when the determined uncorrectable metric meets an uncorrectable threshold and the determined correctable metric is less than a correctable threshold for a persistent period of time, where the non-termination alert indicates a non-terminated pathway to a service provider central office from the premises when service is provided to the premises from a different service provider central office.
