Test call results
• If the test call successfully completes, and every trunk tests within administered thresholds for
marginal and unacceptable performance, then a PASS result is returned.
• If the test aborts or fails, an error code indicating the cause is returned. The error codes are
explained in the CO-TRK and TIE-TRK sections of
ABRI-PORT (ASAI ISDN-BRI Port) in
Maintenance Alarms Reference (555-245-102).
• When the trunk is being used for call processing, the test aborts.
• When the trunk is already being tested by maintenance software, the test is queued and run when
the maintenance activity finishes.
