Testing

You can perform three tests on your ADM: local loopback test, remote loopback test, and self-

test. Taken together, these three tests help you to isolate data communications problems.

Local Loopback Test

The purpose of the local loopback test is to ensure that there are no data transmission errors in

the local part of the data transfer circuit (between the data terminal and the ADM). When the

local loopback test is initiated, data travels from the data terminal to the ADM, where it is looped

back to the data terminal. You can do local loopback tests when the set is idle (local-idle mode)

or when it is engaged in a data call (local-data mode).

To initiate a local loopback test at the CMD: prompt:

1 Type

test local

on your data terminal.

LOCAL LOOPBACK TEST

ENTER ATTENTION SEQUENCE TO END TEST

2 Type characters on your terminal keyboard. They will be echoed on your screen.

If you find no errors, the ADM passed the test.

3 Rapidly type the Attention sequence (default value is +++) to end the test.

LOCAL LOOPBACK TEST ENDED
