Figure 5-2. Remote Loopback Test
Self-Test
The self-test can be used to reset the data options in the Active profile. Unlike
the Data Reset command (see ‘‘Use of the Data Reset Command to Clear a
Lock-up ADM’’ in Chapter 6, ‘‘Troubleshooting’’), which resets the options to
factory default values, the self-test resets all the data options in the Active profile
to their power-up (p1) values without unplugging the ADM. The self-test also
loads the power-up values for the profile independent data options (speed, parity,
and local mode) and the unstored data options (local.cr local.lf, and local.erase).
Activation of the self-test will terminate any voice or data calls in progress.
The procedure for self-test is described in the appropriate User’s Manual as
follows:
