Loopback testing is useful for troubleshooting problems with network connections
should they occur. Looping received data back onto the transmit path helps
determine whether a connection is still valid. Remote loopback tests isolate problems
on the coax run between an iMcV-DS3/E3-LineTerm module and the connected
device, while local loopback tests can isolate problems on the fiber connected to the
module.

The following illustrations show a typical progression of loopback tests (i.e., starting by
checking the coax segment at the local side, then the fiber segment at the remote
side, etc).
