METHOD AND SYSTEM FOR UTILIZING A 10/100/1G/10G BASE-T PHY DEVICE FOR SINGLE CHANNEL AND SHARED CHANNEL NETWORKS

摘要

Aspects of a method and system for utilizing a 10/100/1 G/10 GBase-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 10/100/1 G/10 GBase-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.

1. An Ethernet over twisted pair device configured to communicate over a shared channel with a plurality of link partners, the Ethernet over twisted pair device comprising:
circuitry configured to:
determine a polarity of the shared channel based on data received via the shared channel at a receiver input of a physical layer transceiver (PHY) of the Ethernet over twisted pair device; andadjust a polarity of a transmitter output of the PHY based on the determined polarity of the shared channel, wherein the PHY is configured to transmit data over the shared channel with the plurality of link partners during a plurality of assigned time intervals in accordance with the adjusted polarity of the transmitter output.
