Abstract: A communication device (e.g., a cable modem (CM)) includes a digital to analog converter (DAC) and a power amplifier (PA) that generate a signal to be transmitting via a communication interface to another communication device (e.g., cable modem termination system (CMTS)). The CM includes diagnostic analyzer that samples the signal based on a fullband sample capture corresponding to a full bandwidth and/or a subset (e.g., narrowband) sample capture to generate a fullband and/or subset signal capture (e.g., of an upstream (US) communication channel between the CM and the CMTS). The diagnostic analyzer can be configured to generate sample captures of the signal based on any desired parameter(s), condition(s), and/or trigger(s). The CM then transmits the signal to the CMTS and the fullband and/or subset signal capture to the CMTS and/or a proactive network maintenance (PNM) communication device to determine at least one characteristic associated with performance of the US communication channel.

Abstract: A network device includes a communication interface and a transmitter coupled to the communication interface. The transmitter is configured to determine to start an auto-negotiation page with a link partner, and transmit, through the communication interface, a start delimiter for the auto-negotiation page. The transmitter transmits the start delimiter by transmitting a first pulse comprising a first encoding violation, followed by a second pulse comprising a second encoding violation. The transmitter may shorten the first pulse and the second pulse relative to a different pre-defined start delimiter to define spectral content for the first pulse and the second pulse that passes different first and second receiver filters in the link partner for different first and second communication standards.

Abstract: Method and apparatus to calibrate sampling phases of a multi-phase sampling system. The method includes on-chip generating a pristine phase reference pattern signal for use in generating at least one reference output signal from a data path; sampling, responsive to a clock signal, the at least one reference output signal to obtain samples; and modifying a phase of the clock signal to align the obtained samples to pattern edges of at least one reference output signal. Both symmetric and asymmetric duty cycle distortion are removed from the pristine phase reference pattern signal input to the data path. The effects of asymmetric distortion in the data path output signal upon the phase calibration are cancelled by periodically inverting the at least one reference output signal. The method adjusts a first phase sampling clock signal output of an electronic phase rotator device to provide an initial alignment setting against a first edge of the reference output signal; and then implements phase calibration logic to align a second phase sampling clock signal against a second edge.

Abstract: A Device Abstraction Proxy (DAP) interface receives a request for operational data relating to Digital Subscriber Line (DSL) services provided to a plurality of DSL terminals in a DSL network by two or more providers. The DAP interface receives, in response to the request, the operational data, including operational data for a plurality of DSL lines coupled to the plurality of DSL terminals. The DAP then identifies at least two of the plurality of DSL lines as belonging to a common neighborhood of DSL lines, each of the at least two of the plurality of DSL lines respectively associated with at least two of the plurality of DSL terminals being provided the DSL services by different providers. Embodiments correlate a condition and/or a performance of one of the at least two DSL lines identified as belonging to the common neighborhood with a condition and/or performance of another one of the at least two DSL lines identified as belonging to the common neighborhood.

Abstract: Apparatus, systems, and methods for resolving a forward error correction (FEC) protocol include requesting, by a network node element during an auto-negotiation period between the node element and a link partner, to resolve at least one FEC mode during a data mode period, wherein auto-negotiation period occurs before the data mode period. At least one channel quality parameter of at least one channel of a communication link between the network node element and the link partner are determined by the network node element during the data mode period. The network node determines, during the data mode period, whether to enable or disable at least one FEC mode for use by the network node element based on, at least in part, the at least one channel quality parameter.

Abstract: The invention relates to a method and to a test device (12) which is used to determine an error rate during the transfer of data (1) in a mobile radio system. Said mobile radio system comprises at least one transfer channel, wherein several data partial flows (2.1, 2.2, 2.6) are transferred. The several data partial flows (2.1, 2.2 . . . 2.6) are produced in a signal generator unit (8). A transport format is determined, in an individual manner, for each data partial flow (2.1, 2.2 . . . 2.6). The data partial flows (2.1, 2.2 . . . 2.6) are sent, respectively, to a number of transfer blocks which belong together (5.1, . . . 7.1). A device which is to be tested captures the transfer blocks (5.1, . . . 7.1) of the data partial flows (2.1, 2.2 . . . 2.6) and evaluates them. According to the accuracy of the evaluation, a positive or negative actuation signal (ACK, NACK) is sent back by the device which is to be tested. An error rate of each data partial flow (2.1, 2.2 . . . 2.6) is determined by the test device (12) from the actuation signals (ACK, NACK) which are captured by the test device (12).
