Initiating and Terminating Tests from the Modem’s Front Panel

To initiate a test from the modem’s front panel:

1)Press until you reach the TEST OPTS category.

2)Press until you reach Test=End Test.

3)Press until Test=LAL (for example)

4)Press to start the test.

To terminate a test from the modem’s front panel:

1)Press until Test=End Test.

2)Press to stop the test.

Synchronous Data Compression (SDC) Testing

When performing diagnostic tests in SDC mode, note the following:

•All tests are supported

•When initiating the following “online” tests:

—Remote digital loopback

—Remote digital loopback pattern

—Data mode pattern

—Local digital loopback

during SDC connection, the modem falls back to Direct mode (Mode=Direct, AT*SM) to run the test. If the modem is set for internal timing (Clock=Internal, AT&X) the DTE clock is changed to match the DCE rate. If the modem is set for external timing (Clock=External, AT&X), the clock rate provided may not match the DCE rate and the test will not function. (Set Clock=Internal temporarily to complete testing, and then reset to External.)

•To test the synchronous data path’s integrity while running loopback tests, set the modem for one of the asynchronous buffered modes (Mode=Normal, Reliable, Auto Reliable, or Speed Auto Reliable).
