Step 1: Interface configuration
Allows the channel A data stream to be looped back at the
copper or wireless interface. During normal operation, set it
to 'None'. During installation, it may be helpful to test the
telecoms links by performing loopback connections.
A 'Copper' loopback connects the received data on a given
telecoms interface to the transmit interface. A 'Copper'
loopback may be used, in conjunction with a Bit Error Rate
Tester, to confirm that the correct connections have been
made to the ODU. This mode cannot be used for resistance
tests as it is only capable of looping back valid telecoms
signals.
A 'Wireless' loopback sends the telecoms data received
across the wireless link back across the link on the same
Telecom channel. The link may be checked using, for
example, a Bit Error Rate Tester to ensure that no errors are
detected.
A typical T1 or E1 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.
