communicate with the EPN Maintenance circuit pack. MAINT Error
Type 3329 means the EPN Maintenance circuit pack cannot talk to
the EPN Expansion Interface circuit pack in the A carrier. MAINT
Error Type 3585 means the EPN Maintenance circuit pack cannot
talk to the EPN Expansion Interface circuit pack in the B carrier.
5. Synchronization (SYNC) maintenance may have detected an
inability of the Active Expansion Interface Link to provide
synchronization between cabinets. Examine Error Log for SYNC
Error Type 2305 with the same approximate time as this error.
x. Error Type 11000 with an Aux value of 2 appears when a system
technician-demanded Expansion Interface Link Switch is issued. No
further action is required.
y. Error Type 11000 with an Aux value of 3 appears when a scheduled EI
Link Switch has occurred. No further action is required.
z. Error Type 11000 with an Aux value of 4 appears when an Expansion
Interface Link Switch has occurred due to a Special EPN recovery
strategy. The software has forced an Expansion Interface switch because
the new Expansion Interface Link contains new features which support
EPN recovery in case of a bad tone/clock board. This error code appears
when there is a periodic/scheduled tone/clock switch.
aa. Error Type 11000 with an Aux value of 5 appears when the system has
detected an excessive backup of traffic on the Active Expansion Link. This
condition may have been due to communication difficulties on the
Expansion link. To restore normal service, the system switched Expansion
Links to the link identified in the Error Type 11000 with an Aux Data value
of 5. Error Type 10004 should be present against the Expansion Interface
circuit pack that reported the traffic congestion.
ab. Error type 11000 with an Aux value of 8 indicates that the EI link was
switched as part of the recovery action taken by EPN-SNTY. This error
should be accompanied by EPN-SNTY error 8802 0. If EPN-SNTY error
9902 0 is also present, this indicates that the switching of the EI link was
the recovery action that restored sanity to the EPN. In this case, the fault
was with the link that was switched away from. The relevant EIs and
connections should be tested and examined to determine the cause of the
problem. Look for EPN-SNTY errors in the error log, and refer to the EPN
Sanity Audit (EPN-SNTY) section for more details.
ac. Error Type 11001 occurs when an Expansion Link switch was attempted
but for unknown reasons could not be completed.
Expansion Interface LED Usage
The EI circuit pack has the standard red, green, and yellow LEDs. The red and
green LEDs have the traditional use, where red means some alarm condition and
green indicates maintenance testing in progress. The yellow LED is used to
