Remote Loopback Test
This test requires compatible AT&T equipment at the remote end.
The remote loopback test ensures that no problems with data transmission are
occurring in the data transfer circuit. When you initiate a remote loopback test,
data is transmitted from the module at the far-end, where it is looped back to
your ADM. A data call must be established before you initiate a remote loopback
test.
To initiate a remote loopback test, do the following:
1. Establish a data call.
2. Rapidly type the Attention sequence (default value is +++).
3. At the CMD: prompt, type test remote on your data terminal. The ADM
displays:
REMOTE LOOPBACK TEST
ENTER ATTENTION SEQUENCE TO END TEST
If you are not on a data call, the ADM displays:
Test Remote cannot be used at this time
4. Type characters on your terminal keyboard and check to see they are
echoed as typed.
If you find no errors, the ADM passed the test.
If you find errors, refer to Chapter 6, ‘‘Troubleshooting.’’
5. Rapidly type the Attention sequence (default value is +++) to end the test.
Ending the test does not end the call. You will return to local mode, and
the ADM will be ready to transmit data. The ADM responds:
Call Status: Data Call Active
Type H for help.
6. At the CMD: prompt, type continue to return to Data Mode.
