Loopback testing....

by Peconet Tietokoneet In reply to loopback testing

A loopback test is a test in which a signal in sent from a communications device and returned "looped back", as a way to determine whether the device is working right or as to pin down a failing node in a network. One type of loopback test is performed using a special plug, called a wrap plug, it is inserted in a port on a communications device. The effect of a wrap plug is to cause transmitted (output) data to be returned as received (input) data, simulating a complete communications circuit using a single computer.

In telephone systems, the signal sent as part of a loopback test is referred to as a loopback.,%20Kits,%20Loopback%20Test%20Plugs%20and%20Field%20Termination%20Connector.pdf

Before entering into Phy & below MAC layer instead of pumping the traffic to PHY, Open input Que and fed to entry point above PHY.

So your out put itself your input. You read the protocol now
