1 Alarm Structure
1.1

Alarm descriptions
The Alarm Reference Manual is intended for the operating personnel. It describes the
alarms and diagnosis reports printed out on an alarm output device and contains, when
necessary, instructions for corrective maintenance actions.
The manual contains the alarms of all applications, and therefore it is possible that it also
contains alarms that do not belong to the configuration of a particular customer.
The user of this manual is assumed to understand the operation and the maintenance
of the system. For more information on the alarm system, see About alarm system in
Alarm Administration.

1.2

Structure of the alarm description
Alarms are divided into three groups according to the alarm type. The types are notice,
disturbance printout, and failure printout. Also alarm descriptions are divided according
to these three types.
Alarms of each alarm type are described in a separate document (Notices, Disturbance
Printouts, and Failure Printouts). Also diagnosis report descriptions have the same
structure as alarm descriptions, and they are also described in a separate document,
Diagnosis Reports.
According to the alarm type and the origin of the alarm, the numbering of the alarms
conforms with the following:
Notices
Disturbance Printouts
Failure Printouts
External Alarms
Base Station Alarms

alarm number
1 - 999
1000 - 1999
2000 - 3999
4000 — 5999
7000 — 7999

Diagnosis Reports are numbered with the numbers 3700 – 3999.
The description of an alarm in the Alarm Reference Manual always contains the following parts:
Alarm number

Decimal number on the upper corner of the page

Alarm text

Text in the alarm printout

Meaning

Verbal explanation of the reason for the alarm and of its impact

Supplementary information fields Interpretation of supplementary information fields, if
there are any. The supplementary information fields are indexed from 1
to 32 from left to right.
Instructions

6

Operating instructions for all alarms with urgency level ** or ***. Instructions can also be given for alarms or disturbances with the urgency level
*, but normally they require no actions from the operating personnel.
The instructions are either in written form or in the form of an operating
sequence.

Cancelling

Information on whether the operating personnel should cancel the
alarm, or whether the system does it after the fault situation is over.

A diagnosis report description contains the same parts as the alarm description.
However, a diagnosis report is never cancelled.

Structure of the long alarm printout

In the figure above, the fields marked with the text “optional field” contain user defined
data. If no such data has been defined and the optional field is the only field in the line,
the line is not printed so that there are no empty lines in the alarm printout. According to
the same principle, if the alarm in question does not have any supplementary information fields, the line containing supplementary information fields is not printed. The
second line reserved for supplementary information fields is used only if the supplementary information fields of the alarm do not fit into one line.

1. Type of alarm printout
Alarm history printout
Alarm update printout (when printing out all live alarms at defined
time of the day)
Alarm printout directly from the platform alarm system (indicating
problems in the functioning of the Network element level alarm system)

(1...64)
(A...Z)

DN00158394

In case of a normal alarm printout, the field is empty.
2. Consecutive number
Failure printouts (***, **, *) are numbered in ascending order. With the help of the
number, the operating personnel can follow the update and cancel printouts of the
original failure printout.
3. Name of the network element
4. Name of the remote object (4 characters)
Printed only if the object of the alarm is located in a remote object that has been
named during the configuration of the system.
5. Location information of the alarm object
The location of the alarm object is expressed either with the position co-ordinates of
a subrack and a plug-in unit position address (PPA), or with the HMS (Hardware
Management System) addressing. This depends on how the operator has given the
location information when configuring the alarm object to the system.
The position co-ordinates of the subrack and PPA are output in the form RIV-H-P,
where:
is the number of the cabinet row
is the cabinet identifier in the cabinet row

The location information displayed in the alarm printout does not necessarily contain
all the parts mentioned above. Its accuracy is determined on the basis of the
hardware component which contains the object of the alarm. For example, if the
object of the alarm consists of more than one plug-in unit, the PPA number is not
displayed, or if an alarm concerns the whole cabinet, only RI (or C) is displayed. An
unknown location information is printed as ?????-??-??
6. Alarm event type
Categorization of the alarm for the network management system (NMS). Five basic
categories are specified according to the CCITT Rec. X.733:
communications alarm. Principally associated with the procedures
and/or processes required to convey information from point to point
quality of service alarm. Principally associated with a degradation
in the quality of service
processing error alarm. Principally associated with a software or
processing fault
equipment alarm. Principally associated with an equipment fault
environmental alarm (= external alarm). Principally associated with
a condition relating to an enclosure in which the equipment resides
7. Recovery information
This field displays *RCY* when the alarm system informs the recovery of the alarm.
After this, the recovery starts automatic recovery actions for the object of the alarm.
8. Date
Setting or cancellation date of the alarm
9. Time
Setting or cancellation time of the alarm
10. Urgency level
Alarms are classified according to their criticality from the user's point of view:
***
requires immediate actions
**
requires actions during normal working hours

normally no actions required
The urgency level is output in all alarm printouts except notices (NOTICE). The
urgency levels in alarm cancellation printouts are indicated by dots (.) instead of
asterisks (*).

12. Alarm object
The object of the alarm, expressed either as a single object or in the form of an
object hierarchy.
The alarm object hierarchy consists of five levels at maximum. The first object (the
leftmost in the alarm printout) in the hierarchy identifies the alarm object at the most
general level. The next object in the hierarchy is always a subobject of the preceeding one. Thus, it increases the accuracy of the object identification. Typically the
alarm object is a functional unit or an I/O device. If the alarm is not targeted to any
particular object, this field displays NONE.
If the object (or any of the objects in the object hierarchy) is unknown, its value is
displayed as such (as hexadecimal number) in the alarm printout.
If all of the object names in the object hierarchy do not fit to the field, a question mark
(?) is displayed as the last character in the field.
13. RNW object name
User defined name for the alarming Radio Network object.
Note that this field is possible only for alarms concerning radio network objects. If no
name has been defined for the object, the whole line is left out from the alarm printout.
14. Alarm number
An unambiguous identifier of an alarm. The alarm number is also a search index for
the alarm description.
15. Alarm text
A short description of the event that caused the alarm.
16. Alarm issuer
The program block issuing the alarm.
If the name of the program block issuing the alarm is not available, the family identifier of the program block is output in a hexadecimal form.
17. Computer sending the alarm
The computer unit in which the alarm was issued.
18. Trial information
If the network element has been divided into a original slice and a trial slice (that is,
a trial configuration is in force), this field displays information on which slice the
alarm object belongs to. One of the texts ORIG or TRIAL is displayed.
If the alarm object is not a computer unit belonging to the HW configuration of the
network element itself, the trial information is displayed according to the computer
unit in which the alarm was issued.
19. Processing information
If the alarm is set before the start-up of the distributed part of the platform alarm
system, this field displays LIB. The system cancels this kind of alarm immediately
after its setting. Note that in this case the cancellation does not indicate the termination of the fault that caused the alarm.
20. Flow control information (NMS)
If sending the alarm to network management system Nokia NetAct has been prevented, this field displays NMS.
21. Flow control information (LPT)
If printing the alarm via logical files has been prevented, this field displays LPT.
22. Flow control information (OUT)
If the effect of the alarm on the state of an external alarm output has been prevented,
this field displays OUT.

23. Flow control information (RCY)
If the effect of the alarm on activating recovery actions has been prevented, this field
displays RCY.
24. Supplementary information fields
A maximum of 32 fields which are separated from one another by one or several
spaces. If all the fields do not fit into one line, they are printed out on two lines. The
left margin of the line is shifted left if printing the fields on two lines can be avoided
by that. The following are the possible values of the fields:
a hexadecimal number (e.g. 0120)
a decimal number
(e.g. 288d)
a BCD coded number
(e.g. 0288)
If the number is BCD coded, it is mentioned in the alarm
reference manual in the explanation of the field in question
a single character or characters (e.g. ULHISTGX)
a functional unit (e.g. OMU)
a plug-in unit (e.g. EHAT)
a working state of a unit (e.g. WO-EX)
a date (e.g. 2008-05-13)
a time (e.g. 11:14:42.19)
an IPv4 address (e.g. 131.255.0.12)
an IPv6 address (e.g. 1080:0:FE:0:0:225:34:FFFF)
In addition, the value of a certain field (for example, the index of a functional unit or
the index of a plug-in unit) can be displayed as two dots (..).In this situation the field
cannot be given a single value according to its meaning.
If the amount of supplementary information data does not match with the formatting
information, a question mark (?) is printed at the end of the fields.
25. Supplementary text
A more detailed text printed out in some alarms. The left margin of the line is shifted
left if the text is longer than 76 characters.
Please note that this field may not be identical between the setting and cancellation
printouts of the alarm.
26. Alarm operating instructions
Operating instructions the user may have defined for an alarm. The left margin of the
line is shifted left if the text is longer than 76 characters.

INFORMATION
FIELDS

The plug-in unit does not respond to the HMS messages sent to it.
The plug-in unit is damaged or the connection to the plug-in unit
is cut. When the alarm is on, the HMS communication is not working
to/from the plug-in unit. E.g. hw-alarms and restart notifications
are not received from the plug-in unit, and the forced reset and
separation from use cannot be done to the plug-in unit.

1

type of the plug-in unit detecting the fault

2

number of the rack in which the plug-in unit is located

3

number of the subrack in which the plug-in unit is located

4

location of the plug-in unit in the subrack (= slot number)

INSTRUCTIONS

Check the cabling between the subracks and the wiring of the
backplate, see instructions on interconnection cables. If the
cabling is correct and this alarm concerning the other plug-in
units of the subrack is not on, the fault is obviously in the
plug-in unit. Change the faulty plug-in unit indicated in the
additional information of the alarm, see instructions on
replacing plug-in units.
If the alarm concerning the other plug-in units of the subrack is
on as well, the HMS-bridge might be damaged. Change the plug-in
unit of the subrack indicated in the additional information of
the alarm, the plug-in unit which has the HMS-bridge node of the
subrack.

CANCELLING

Cancel the alarm with an MML command after correcting the fault
as presented in INSTRUCTIONS. See alarm administration instructions.
