Abstract: Signals may be communicated with A/V Bridging services between an upstream link partner and a down stream link partner, each comprising an asymmetric multi-rate Ethernet physical layer (PHY). High bandwidth A/V signals may be transmitted from the upstream link partner and low bandwidth signals may be transmitted from the downstream link partner. One or more of a time stamp, a traffic class and/or a destination address may be utilized in generating PDUs as well as data rate request and a resource reservation messages via the asymmetric Ethernet PHY. The receiving link partner may register for deliver of the PDUs. An aggregate communication rate may be distributed evenly or unevenly among one or more links for transmission and aggregated upon reception via asymmetric multi-rate Ethernet PHY operations. Compressed, uncompressed, encrypted and/or unencrypted signals may be handled. Signal processing may comprise echo cancellation, cross talk cancellation, forward error checking and equalization.

Abstract: A system and method for continual cable thermal monitoring using cable characteristic considerations in Power over Ethernet (PoE) applications. Cable heating in PoE applications is detected through changes in electrical characteristics of the cable itself. By periodically monitoring the electrical characteristics such as insertion loss or cross talk of the cable, it can be determined whether the cable has exceeded certain thermal operating thresholds.

Abstract: Aspects of a method and system for utilizing a 10/100/1G/10GBase-T PHY device for single channel and shared channel networks are provided. In this regard, at least one switching element may be utilized to configure an Ethernet over twisted pair PHY device for communication over a single and/or shared channel. The switching element may enable switching between a transmitter being coupled to a shared channel and a receiver being coupled to a shared channel. Additionally, the switching elements may be based on whether the transmitter is connected to a standard 10/100/1G/10GBase-T network, or to a single and/or shared channel network, for example. In this manner, the configured PHY device may remain compatible with existing Ethernet networks. The PHY device may be configured externally and/or internally. The polarity of transmitted and/or received data may be configured based on a polarity of data received from a shared channel.

Abstract: In a multi-carrier transmission scheme (frequency domain multiplexed—FDM), a single high rate data stream is split into multiple lower rate data streams each transmitted over a different carrier (e.g., a tone or bin). The data rate possible from a multiple-carrier transmission scheme is theoretically equivalent to the data rate possible from a single-carrier (including baseband) scheme with the same composite bandwidth. The scheme allows for a communications system that can selectively send each data signal (e.g., audio data, video data, raw data, etc.) partitioned out into full and half duplex sections (e.g., tones). The scheme can have a reduced complexity and cost and use less bandwidth. This is done by being able to selectively split a data signal into both full and half duplex tones.

Abstract: Aspects of a method and system for an asymmetric physical (PHY) layer in extended reach Ethernet local area networks (LANs) are provided. Reducing the communication rate provided by an asymmetric Ethernet multi-rate PHY may extend the standard distance over twisted-pair cabling where customer premises equipment (CPE) may be located in the MTU. Downstream and upstream rates may be aggregated evenly or unevenly over each twisted-pair wire in the copper cabling. The asymmetric Ethernet multi-rate PHY may support signal-processing operations, such as echo cancellation and/or equalization, which may be applied to the reduced communication rate to enable range extension. The reduced communication rate may be achieved by reducing the symbol rate provided by the asymmetric Ethernet multi-rate PHY. Reducing the communication rate may also enable utilizing cabling with greater insertion loss than those used for a standard connection distance.

Abstract: A system, method and apparatus for reducing a power consumed by a physical layer device (PHY). A length of a cable connecting the PHY to a link partner is determined. Based on the length, power provided to one or more components of the PHY, or any portion thereof, is reduced. The power provided is reduced while maintaining a level of reliability specified by a protocol governing operation of the PHY. The length can be determined using time-domain reflectometry (TDR) techniques. Any portion of an echo cancellation filter, a crosstalk filter, an equalizer, a precoder, an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), a forward error correction (FEC) decoder and/or an FEC coder can be powered-down or power-optimized to reduce the overall power consumed by the PHY. The protocol governing operation of the PHY can be IEEE 802.3.
