Test Branch

Loc Digital Loop

Loc Digital Loop is issued by a local modem and forces it to loopback any data received from the remote modem (Figure 7-3). (This test operates the same as a CCITT V.54 Loop 2 except it is issued at your modem.) This is useful if a remote modem is incapable of initiating a remote digital loopback from its location. For this test to operate properly, the modems must be online and in Synchronous or Asynchronous Direct mode and, if set for V.34 modulation, must not be in Asymmetric Rate mode.

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

Test :

Loc_Digital_Loop

F1 F2 F3

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

Test : Digitl Loop

Started

F1 F2 F3

The message Started appears on the LCD and the Test LED lights.

If the message Invalid Command appears on the LCD, then another test is in progress. Select Abort to clear the current test and then select Loc Digital Loop.

If the Test Timeout configuration option is enabled, Test Timeout appears at the conclusion of the LCD. 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.

To exit this function and remain in the Test branch,

press the key. To exit and return to the Top-Level

menu, press the key.
