EXP-INTF (Expansion Interface Circuit Pack)
2. If the alarm is not resolved within the next 15 minutes, replace the EI circuit pack
reporting the alarm.
3. If the alarm is not resolved within the next 15 minutes, replace the connected EI circuit
pack, SNI circuit pack, or DS1 converter circuit pack.
t. Error Type 3841: the EI has reported a loss of lock with the backplane system clock.
u. Error Type 3842: the test that queries the EI for the state of the lock to the system clock has
failed. A loss of lock condition is present.
v. The counter associated with Error Types 3841 and 3842 is cleared when the query for the
state of the clock-to-system-clock passes. Once the alarm is raised, this test is run every
five minutes. However, the test is not part of any sequence that can be run on demand. See
previous Note p for the repair procedure.
w. Error Type 10001: the EI circuit pack dropped one control message to the PN. This
condition may have been observed as a call that did not complete correctly. No action is
required.

Investigate tests in the order presented. By clearing errors associated with the first test, errors
generated from other tests may also be cleared. Click on the link to see the full description of
the test, error codes, and recommended actions.
When testing EI circuit packs to investigate problems, tests should always be run on both circuit
packs on the associated fiber link, whether the circuit packs are both EI circuit packs, or one is a
SNI circuit pack. This will provide a better indication of where a problem is located.
When testing of the EI is not possible, (for example, when the PN is down), see the Expansion
Interface Manual Loopback Procedure.
