Performing a Loop Back Test
The Loop Back Test simulates an inbound H.320 call to a LiveLAN client. This test loops back video and audio
at the H.320 subsystem within the LiveGateway board. All LiveLAN to H.320 transcoding paths are exercised.
To perform a Loopback Test on a LiveGateway Board:
1.
Open the LiveGateway server from the LiveGateway SNMP Manager window.
2.
Select the Gateway Boards tab of the LiveGateway Server window.
3.
Perform one of the following actions:
•
Click on a board in the list to highlight the board, and select Operations-> Loop
Back from the LiveGateway Server window's menu bar.
•
Right-click your mouse when it is positioned over the board's entry line and
select "Loop Back" from the popup menu.
4.
The Loopback dialog box appears. Enter the name of the Diagnostic H.323 Terminal ID
in the text field.
5.
Click the Start Loopback button. After the Loopback test starts, the Board Status
changes to Loopback, and the push button caption changes to "Stop Loopback."
6.
To stop the Loopback test, click the Stop Loopback button.
If the LiveGateway board is in a download or self-test state, you cannot run the loopback test, and the Start
Loopback selection on the Operations menu selection appears dimmed.
