Troubleshooting

DTE Loopback

The local DTE external Loopback (DTLB) test loops the received signal on the DTE interface back to the DTE without affecting the operation of the remaining ports. Use this test to isolate problems on the user data port.

Main Menu → Test → Data Port Physical Tests

An attached device or test equipment must generate the data to be looped back.
