System Configuration and Operation Alarms
5.7.3 Alarm Modifiers
Each alarm may also be designated as I=info, m=minor, M=major or C=crit. The filter
modifier appears on both the active alarm and alarm history screens.
If the system has an External Alarm card (optional), the occurrence of any alarm designated
as crit will trigger a form-C relay contact on the External Alarm card. The relay contact action
sets off an annunciator or lamp at the equipment site. Similarly, the occurrence of any alarm
designated as major triggers a different contact and activates another external indicator. Refer
to the Alarm Card Reference Guide for more information on the External Alarm cards.
SYNC Clock Sync Alarm The SYNC alarm is generated when either the primary or secondary external
clock source is lost. This alarm is in addition to the condition that lost the
clock source (CGA-RED or OOS).
ERR-3 Excessive Error Rate (10e-3) While using transcoder operations for E1 that involve downstream
tributaries, setting EER-3 to “report” will cause an alarm to appear on the
local system when E1 transmission errors exceed 10e-3 (1 in 1000). The
local EER-3 alarm will identify the effected WAN link (i.e., W1-1) and take
it out of service. Simultaneously, the downstream tributary will receive an
AIS alarm to warn them of the condition.
OC3_LOF OC3 Loss of Frame
OCS_LOS OC3 Loss of Signal
OC3_LOPP OC3 Path Loss of Pointer This alarm is currently not used, and will be removed in the next release.
INSERT Card Insert SNMP only report - trap generated on card insertion
REJECT Card Reject Does not appear in the banner, but displays in active alarms and history.
Shows that an inserted card has been placed into a slot, but the slot is
provisioned for a different card. The user must accept the REJected card in
order for service provisioning.
DELETE Card Deleted SNMP only report - trap generated on card deletion.

CLEARED
History Cleared The command to clear alarm history has been utilized.
UPGRADE Upgrade A card upgrade has been started on a card that has only one memory bank:
WAN, IPR*4, OC3 and PWE cards.
WAN RR Main WAN redundant A WAN protection switch is currently active, and the flagged WAN card is
now operating as the WAN RR resource - other WANs are no longer
protected. The customer should work to restore WAN 4 as the redundant card
to ensure 1+n redundancy on the shelf.
AMT ACT Alternate Map Active The Alternative Mapping Table feature is activated, and the system has
switched to running the Alternative Map.
SYNC AMT Alt Map Out of Sync The Alternative Mapping Table feature is activated, and the system has
detected that the basic shelf configuration has changed, making the
Alternative Map unusable. The customer needs to update the Alternative
Mapping Table in order to clear the SYNC AMT alarm.
RED Red Alarm An OHSU User card will raise the RED alarm when one of the ports reports
a red alarm condition.
OOF Out of Frame Alarm An OHSU User card will raise the OOF alarm when one of the ports reports
an out-of-frame alarm condition.
FPALARM OC3 Faceplate Alarm
