If the loopback test fails

Follow these suggestions to track down the reason behind the loopback test’s failure:

■Check that the WAN Ready LED is solid green.

■Check the ISDN event log and get more information about events that seem relevant to the failure.

■Check the B-channel usage in the Quick View screen to make sure there were no active calls when the loopback test was performed.

■Check the accuracy of the directory numbers, SPIDs, and switch protocol you entered in the ISDN Line Conﬁguration screen (compare them with the information you received from your ISDN service provider).

■Verify termination of the S/T bus.

■Contact your ISDN service provider to have the line checked.

■Check that your line is not provisioned for voice only (Circuit Switched Voice).
