Loc Analog Loop, Test LocAnalogLoop | Paradyne 3800PLUS instruction

Test Branch

Loc Analog Loop

Loc Analog Loop performs a local analog loopback (CCITT V.54 Loop 3), Figure 7-1, that verifies modem operation as well as the connection between the DTE and modem. The modem must be offline and in synchronous or asynchronous Direct mode to perform this test, otherwise Invalid Command appears.

To access Loc Analog Loop from the Test branch, make the following selections:

Test :

Loc_Analog_Loop

F1 F2 F3

Press the key until Loc Analog Loop appears. Press any function key to start this test.

Test : Local Loop

Started

F1 F2 F3

The message Started appears on the LCD, and the Test LED lights for the duration of the test.

If the Test Timeout configuration option is enabled,

Test Timeout appears at the conclusion of the test. If it is disabled, the test operates until aborted. For more information on the Test Timeout configuration option, refer to the Tests section in Chapter 7, Configure Branch.

A Ring Indicate during this test can cause errors.
