Expansion Interface Local Looparound (#240)
This test is nondestructive. The EI local loop around is similar to the Lightwave
Transceiver Looparound test (#242). A test tone is received by the EI being
tested, but is not transmitted out to the fiber interface before being looped back.
The loop back is internal to the circuit pack. Thus, this test does not interfere with
the normal fiber data stream.

Description / Recommendation
1
ABORT
Could not allocate time slot on TDM Bus A. Loop back passed on TDM Bus B.
2
ABORT
Could not allocate time slot on TDM Bus B. Loop back passed on TDM Bus A.
1. If there is no reason to doubt that the EI circuit pack can transfer data to or
from a TDM Bus, then since the test passed on one bus, assume that the
test passes on the other bus.
2. If this test continues to abort with the same error, rerun test at 1-minute
intervals up to 3 times.
3. If the test still does not pass on the other TDM Bus, follow the procedure
for ABORT Error Code 3.
3
ABORT
The system could not allocate time slots for the test on either TDM Bus. The
system may be under heavy traffic conditions or it may 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. Enter display errors and follow associated repair procedures for TTR-LEV
errors in the error log. Even if there are not TTR-LEV errors, there 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 the network.
If not, this test always aborts for this EI circuit pack. This does not harm
the system.
2. Resolve any TONE-PT errors.
3. If neither condition exists, retry the command at 1-minute intervals up to 3
times.
1031
ABORT
A query of the EI circuit pack aborted. The purpose of this query was to see if
the EI circuit pack could detect the framing signal.
1. If Test #238 aborted, follow the procedure associated with this abort code.
2. If Test #238 did not abort, rerun Test #240 at 1-minute intervals up to 3
times.
