ATM-EI (Expansion Interface Circuit Pack)
Issue 1 June 2005 553
Expansion Interface Lock Query Test (#304)
This test is nondestructive and is used to query the ATM and EI circuit packs (both active and
standby) for its status concerning lock to the backplane system clock. It is run as part of
periodic, scheduled, initialization, and error analysis testing. When an in-line, “out-of-lock”
report comes in, this test is run to check the circuit pack’s status. The ATM-EI responds with “in
lock” or “out of lock.” If the response is “in lock,” the test passes; if the response is “out of lock,”
the test fails.

Description / Recommendation
2000 ABRT Response to the test request was not received within the allowable time
period.
2100 ABRT Could not allocate the necessary system resources to run this test.
2500 ABRT Internal system error
1. Retry the command at 1-minute intervals up to 3 times.
FAIL A PN’s unduplicated ATM-EI circuit pack responded incorrectly, or a PN’s
active ATM-EI circuit pack could not communicate with the PN’s circuit
packs.
1. If the PN’s active ATM-EI circuit pack is failing and duplicated PNC is
enabled:
a. Enter reset PNC interchange to switch to the standby PNC.
b. Repeat the short test sequence.
c. If test continues to fail, enter reset board location to reset the
ATM-EI circuit pack.
2. If the PN’s unduplicated ATM-EI circuit pack is failing:
a. Enter display errors and display alarms, and follow the
associated repair procedures for TDM-CLK, TONE-BD, or SYNC
alarms/errors.
b. Repeat the short test sequence.
c. If test continues to fail, replace the circuit pack or transceiver.
PASS Communication from software to the ATM-EI circuit pack is functioning
correctly.
