2.3 Alarm Logical Objects
2.3 Alarm Logical Objects
The CTC alarm profile list organizes all alarms and conditions according to the logical objects they are
raised against. These logical objects represent physical objects such as cards, logical objects such as
circuits, or transport and signal monitoring entities such as the SONET overhead bits. One alarm can
appear in multiple entries. It can be raised against multiple objects. For example, the loss of signal (LOS)
alarm can be raised against the optical signal (OC-N) or the optical transport layer overhead (OTN) as
well as other objects. Therefore, both OCN: LOS and OTN: LOS appear in the list (as well as the other
objects).
Alarm profile list objects are defined in Table 2-7.
Note Alarm logical object names can appear as abbreviated versions of standard terms used in the system and
the documentation. For example, the “OCN” logical object refers to the OC-N signal. Logical object
names or industry-standard terms are used within the entries as appropriate.
Table 2-7 Alarm Logical Object Type Definitions
Type Definition
BITS
Building integrated timing supply (BITS) incoming references (BITS-1, BITS-2).
BPLANE
The backplane.
CE100T
The CE-100T-8 card.
DS1
A DS-1 port on the 15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3
card.
DS3
A DS-3 port on the 15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3
card.
EC1
A EC-1 port on the 15310-CL-CTX, DS1-28/DS3-EC1-3, or DS1-84/DS3-EC1-3
card.
ENVALRM
An environmental alarm port.
EQPT
A card, its physical objects, and logical objects as they are located in any of the
noncommon card slots. The EQPT object is used for alarms that refer to the
card itself and all other objects on the card including ports, lines, synchronous
transport signal (STS), and virtual tributary (VT).
EXT-SREF
BITS outgoing references (SYNC-BITS1, SYNC-BITS2).
FAN
Fan located in the ONS 15310-CL or ONS 15310-MA shelf.
FUDC
SONET F1 byte user data channel for an ONS 15310-CL or ONS 15310-MA
ML-100T-8 Ethernet card.
NE
The entire network element.
NE-SREF
The timing status of the NE.
OCN
An OC-3 port or OC-12 port on the 15310-CL-CTX or CTX2500 card.
PPM
Pluggable port module (PPM, also called SFP).
PWR
The node power supply.
SHELF
The ONS 15310-CL or ONS 15310-MA shelf.
STSMON
STS alarm detection at the monitor point (upstream from the cross-connect).
