5. If the alarm is not resolved within the next 15 minutes, replace the
connected Expansion Interface circuit pack, Switch Node Interface
circuit pack or DS1 CONV circuit pack.
q. Error Type 3841 indicates the EI has reported a loss of lock with the
backplane system clock.
r. Error Type 3842 indicates that the test that queries the EI for the state of
the lock to the system clock has failed. This means that a loss of lock
condition is present.
s. 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 Note “p” above for
repair procedure.
t. Error type 10001 is a report that the Expansion Interface circuit pack
dropped one control message to the EPN. This condition may have been
observed as a call that did not complete correctly. No system technician
action is required.
