1.4.6 Loop Back Test Function

As illustrated in the following figure, the local MC starts a loop back test by pressing the loop back test button.
It sends test frames from its FX port to the remote MC. The remote MC forwards the received test frames back
to local MC from its FX port. The local MC verifies the loop back test frames and display the test result on
RTP LINK/100M/FDX LEDs. This function can help installer to check the full path from a local MC through
fiber to a connected remote MC and back to local MC.
