Expansion Interface Control Channel Test (#316)
This test is non-destructive. If an ATM-EI circuit pack is an
active
ATM-EI in the
EPN (yellow LED on long/off short), the Expansion Interface Control Channel test
checks to see if the ATM-EI circuit pack c an communicate with other c ircuit
packs in the EPN using the EPN TDM bus.
If the circuit pac k is a

standby

ATM-EI (yellow LED off) or if the ATM PNC
Expansion Interface is in the PPN (yellow LED on), this test queries the ATM PNC
Expansion Interface circu it pack for its circ uit pack type and vintage information.

Error
Code Test Result Description/ Recommendation
2000 ABORT Response to the test request was not received within the allowable
time period.
2100 ABORT Could not allocate the necessary system resources to run this test.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 3 times.
FAIL The ATM-EI circuit pack responded incorrectly or if it is the EPN
active ATM-EI circuit pack, it could not talk to EPN circuit packs.
1. If the active ATM-EI circuit pack in the EPN is failing and
duplicated PNC is enabled, attempt to switch to the standby PNC
using the reset PNC interchange command.
2. Repeat the short test sequence.
3. If test continues to fail, reset the ATM-EI circuit pack with the
reset board UUCSS command.
4. If the ATM-EI circuit pack in the EPN is failing, enter display
errors and display alarms and resolve any TDM-CLK, TONE-BD,
or SYNC alarms/errors and repeat the Short Test Sequence.
5. If test continues to fail, replace the circuit pack or transceiver.
PASS The ATM-EI circuit pack did respond correctly to test. Communication
from software to the ATM-EI circuit pack is functioning.
1. Refer to other ATM-EI circuit pack tests if the link is not
functioning correctly.
