Multi-station physical layer communication over TP cable
First Claim
1. A method for providing network communications between a first and a second network device associated with a first node of a network and a third network device associated with a second node of the network, in a wired data telecommunications network, the method comprising:
- directing simultaneously, from the first network device, network communications to the third network device and to the second network device at a first speed through a Y-device;
directing simultaneously, from the third network device, network communications to the first network device and to the second network device at the first speed through the Y-device;
monitoring network communications between the first network device and the third network device with the second network device; and
detecting at the second network device a condition in the network communications between the first network device and the third network device.

Abstract
Wired data telecommunications networks can make advantageous use of a communications capability between and among more than two network devices. Such capabilities may be utilized in providing redundancy of data and/or inline power capabilities from a pair of network devices to a third network device receiving the redundant capability. Impedance modulated communications are provided in a wired data telecommunications network among at least a first, second and third network device coupled together via a Y device. The Y device couples the three network devices (higher order Y devices could couple more than three devices) allowing monitoring of communications and inline power provision so that one of the network devices may act in response to monitored conditions by communicating via impedance modulated communications with one or both of the other network devices.
