A "Wireless" loopback sends the telecoms data received across the wireless link back across
the link on the same channel. The link may be checked using, for example a Bit Error Rate
Tester.
A typical E1 or T1 installation might include a "Copper" loopback on the local unit followed by
a "Wireless" loopback on the remote unit.
It is important to remove all loopbacks on channels for normal operation.
Alarms on the Home Page indicate the presence of loopbacks on either channel.
