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.
PASS PI-LINK currently does not have any of the above errors.

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.
