•

Copies the incoming signal back out to the origin while continuing to

transmit this signal downstream.

•

Blocks downstream data from arriving on the looped data line.

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/STS-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).
