ISDN Hardware Check Test (#234)
This test checks the status of the ISDN hardware which is the DS1 Interface
circuit pack and cabling. Status of the DS1 port is kept by the system. The state of
the port can be in-service or out-of-service. This state is updated by DS1 Interface
circuit pack maintenance. If DS1 maintenance detects a problem with the physical
medium near-end or far-end, the Processor Interface Link maintenance is
instructed to restart the link. Therefore, if this test fails, the port is considered
out-of-service and the link cannot be brought up until DS1 maintenance changes
the state to in-service. This is more of a status inquiry than a test. Thus, the only
recovery procedure is to refer to DS1-BD (DS1 Trunk Circuit Pack) Maintenance
documentation.

Result Description/Recommendation
ABORT Internal system error
1. Retry the test at 1-minute intervals a maximum of 5 times.
1005 ABORT This test only runs for ISDN-PRI links. This link is a BX.25 link
and, thus, aborts.
FAIL Indicates that there is a physical problem with the DS1 facility link.
1. Cross-reference DS1 Interface circuit pack errors for possible
reason. Refer to “DS1-BD”.
2. Retry the test. It continues to fail until the DS1 problem is
cleared up.
PASS DS1 facility is functioning correctly.
