NOTE: The following two commands initiate a loopback test, illustrated
in Fig. 5-6. The channel configuration and the test pattern should not be
changed during a loopback test.
Figure 5-6 Loopback Test
Remote Loop Up
Allows the user to send the loopup code to the remote bridge. This
initiates a diagnostic test which determines the status of the T1 Link.
To initiate a loopback test:
1. Use the Right Arrow key to highlight Remote Loop Up.
2. Press Return to initiate the loopback test. The bridge Status field will
be Disabled while the loopback test is being performed.
Remote Loop Down
Allows the user to send loopdown code to the remote bridge. This restores
the DSX-1 back to operational (non-testing) condition.
To revert from a loopback test to operating condition:
1. Use the Right Arrow key to highlight Remote Loop Down.
2. Press Return to revert from testing to operating condition.
If Remote Loop Down is not performed within 5 minutes after initiating
Remote Loop Up, the DSX-1 port will automatically perform Remote
Loop Down.
