Chapter 5: Diagnostics and Troubleshooting

You can use local and remote loopback tests to test individual ports while 
the ATX is operational. When in local loopback, a port is disconnected 
from its network. The ATX generates loopback packets for the port, and 
the port loops the packets back without sending them onto its network.

During a remote loopback test, the port is in normal operation, sending 
and receiving packets to its network. The ATX generates loopback 
packets which are sent out of the port to a particular destination device on 
the ports network. The destination device echoes the packet back onto the 
network, and the originating port receives the packet.
