5. Troubleshooting

Physical Tests (9720, 9783, 9788 CSU/DSUs)

iMarc DSL CSU/DSUs support a single physical test for the data port, the
DTE Loopback. This test does not appear for the routers.

DTE Loopback (9720, 9783, 9788 CSU/DSUs)

The local DTE external Loopback (DTLB) 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.
An attached device or test equipment must generate the data to be looped back,
and the Port (DTE) Initiated Loopback option must be enabled. Refer to the
SLV Configuration
