Before a maintenance test can be run on a port, the port must be idle. If an
incoming call seizes a port that is being tested, the test will abort and the
incoming call will proceed.

Ports Out-of-Service without Errors or Alarms
A common trouble on DID trunks that produces no errors or alarms occurs when
the CO busies out (disconnects) the port. This situation occurs when the CO
thinks there are problems with the DID port. In this case, no incoming calls will be
possible through this port. This may result in complaints from outside callers
trying unsuccessfully to call in. This problem can be diagnosed by listing
measurements on lightly used trunks. If a particular port is detected as not in
use, a call to the CO will be necessary to get the connection back in service.
