Figure 5-2 Ethernet Line Loopback
Internal Line Loopback
An Internal loop returns the traffic to be transmitted out of the line port to the bridge.
From the bridge the traffic is transmitted over the radio.
Connect the Ethernet traffic from the Customer’s end-equipment or Ethernet analyzer
to the local radio and apply line loopback on remote radio for end-to-end testing. This
will allow you to test the connection (cable/fiber) to the local radio, the interface
between end-equipment and the local system, both local and remote systems and the
radio transmission.
5.4.3 Radio Loopbacks
The loopback can be applied separately for each one of the radio interfaces (on a TU –
one radio interface towards the BU, on a BU – up to 8 radio interfaces towards each on
the TUs) with MAC Address swapping.
Set the loopback mode for the desired radio interface and set the loopback-timeout in
seconds (default 60 seconds, up to 24 hours, 0= no timeout).
Radio loopbacks can be set in the Maintenance section of the Radio page.
