ATM-EI (Expansion Interface Circuit Pack)
Issue 1 May 2002

If the test fails for every DSP, a MAJOR alarm is raised against the board. If the
test fails for one or more DSPs, a MINOR alarm is raised. If a DSP is busy, the
test for that particular DSP is considered passed. The test aborts if the system
resources (for example, the TDM time slots, Tone Generator, and others) are not
available.
This test applies to TN2305 and TN2306 ATM-EIs, both active and standby, and is
run as part of craft short and long testing, periodic, scheduled, initialization, and
error analysis testing. Refer to Figure 8-8 for a diagram of this loop-around test.

Result Description / Recommendation
1002 ABORT The system could not allocate time slots for the test. The system could be
under heavy traffic conditions or it could have time slots out of service due to
TDM-BUS errors.
1. If the system has no TDM-BUS errors and is not handling heavy traffic,
retry the command at 1-minute intervals up to 3 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. Verify that at least one Tone Detector resides in this EPN. (Even without a
TTR-LEV error, the tested circuit pack’s EPN could be missing a Tone
Detector.)
If missing, the test always aborts for this circuit pack, without harming the
system.
2. Resolve any TONE-PT errors.
3. If neither condition exists, retry the command at 1-minute intervals up to 3
times.
