Chapter 2 Alarm Troubleshooting

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).
