NOTE:
When the Expansion Interface circuit pack under test is an EPN, the data
packet must also pass through the Active Expansion Interface circuit packs
of the Active link connecting the EPN to the PPN.
This test requires the Expansion Interface circuit pack to ignore incoming data
from its neighbor Expansion Interface circuit pack on the opposite end of the
fiber. Thus, this test disturbs any inter-cabinet connections that currently exist
and disrupts signaling between the two cabinets.

Test
Result Description/Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
1002 ABORT The system could not allocate time slots for the test. The system may be
under heavy traffic conditions or it may have time slots out-of-service due
to TDM-BUS errors. Refer to TDM-BUS (TDM Bus) Maintenance
documentation to diagnose any active TDM-BUS errors.
1. If system has no TDM-BUS errors and is not handling heavy traffic,
repeat test at 1-minute intervals a maximum of 5 times.
1003 ABORT The system could not allocate a tone receiver for the test. The system may
be oversized for the number of Tone Detectors present or some Tone
Detectors may be out-of-service.
1. Look for TTR-LEV errors in the Hardware Error Log. If present, refer to
TTR-LEV (TTR Level) Maintenance documentation. Even if there are no
TTR-LEV errors, there still may not be a Tone Detector available on the
network that contains the circuit pack being tested. Verify that there is
at least one Tone Detector on this network. If there is not at least one
Tone Detector, this test always aborts for this Expansion Interface
circuit pack. This does not harm the system in any way.
2. Look for TONE-PT errors in the Hardware Error Log. If present, refer to
TONE-PT (Tone Generator) Maintenance documentation.
3. If neither condition exists, retry the test at 1-minute intervals a
maximum of 5 times.
1015 ABORT The system does not allow this test to be run because the Expansion
Interface circuit pack has not been busied out.
1. Busyout the Expansion Interface circuit pack. Repeat the test board
PCSS long command.
