Alarms overview

Alarm Structure

1 Alarms overview
The DX 200 system's alarm reference documentation is intended for maintenance personnel working with DX 200 network elements. The documentation describes the alarms and diagnosis reports printed out on a terminal device and contains, when necessary, instructions for corrective maintenance actions. Since several DX 200 applications may use the same DX 200 software platform, it is possible that the alarm reference documentation also contains alarms that do not belong to the configuration of a particular customer. It is assumed that you have taken the DX 200 system course and the operation and maintenance course. For more information on the alarm system, see Alarm system in BSC in Alarm Administration. For information on alarm printout structure, see section Alarm printout. BSC alarm information is also directly available and accessible via NOLS Documentation Center's Reference Information service.

1.1

Alarm groups and numbers
The alarms in alarm reference documentation have been divided into six groups, and each of them is described in a dedicated piece of documentation. The alarms are numbered in ascending order as follows:
Notices (NOTICE) Disturbance printouts (DISTUR) Failure printouts (ALARM) Diagnosis reports (DIAGN) Base station alarms Transmission equipment alarms 0 - 999 1000 - 1999 2000 - 3999 3700 - 3999 7000 - 7999 8000 - 8999

1.2

Alarm description
The alarm description always contains the following parts: 1. Alarm number: Decimal number on the upper right hand corner. 2. Text: The text in the alarm printout. 3. Meaning: Verbal explanation of the reason for the alarm and of its impact. 4. Supplementary information fields: Interpretation of supplementary information fields, if there are any. The supplementary fields are indexed from 1 to 32 from left to right. 5. Instructions: There are instructions for all alarms that have been classified with the urgency level major (**) or critical (***). Instructions may also be given for alarms or disturbances

with the urgency level minor (*); however, minor alarms normally do not require any actions from you. The instructions given here are in written form. If the instructions are given in the form of an operating sequence, they are presented in a document of their own. The electronic documentation gives the operating sequence here. 6. Cancelling: Information on whether you should cancel the alarm or whether the system does it after the fault situation is over.

Figure 1

DX 200 alarm printout fields

Note that the fields marked as 'optional' in the figure contain user-defined data. If you have not defined such data for the alarm, the line is not printed; consequently, there are no empty lines in the alarm printout. According to the same principle, if an alarm does not have any supplementary information fields, the line containing supplementary information fields is not printed. The second lines that have been reserved for supplementary information fields (18) and alarm operating instructions (20) are only used if the data in question does not fit on one line. 1.

The urgency level is output in all alarm printouts except notices (NOTICE). The urgency levels of terminated alarms are indicated by dots (.) instead of asterisks (*). 8. Printout type ALARM fault situation CANCEL fault terminated DISTUR disturbance NOTICE notice 9. Alarm object The functional unit which is the object of the alarm. If the alarm is not targeted to any particular object, the field displays eight dots. 10. Position coordinates of the alarm object Position coordinates are expressed in the form RTK-V, where: is the rack row is the rack is the vertical position of the subrack or cartridge in the rack V (00...99) is the horizontal position of the subrack or cartridge in the rack If a rack is the object of an alarm, only RT is displayed. An unknown position coordinate is printed as ??????-?? 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 hexadecimal form instead of the name. If the alarm is set in a preprocessor plug-in unit, the plug-in unit name and index are output in this field (for example PCU_S-1). In this case, the alarm concerns the functioning of the plug-in unit in question. Trial information If the network element has been divided into a traffic transmitting part and a trial part, this field displays the text TRIAL if the alarm was issued in the trial side. Recovery information When recovery is informed of the alarm in order to start the automatic recovery actions, this field displays *RECOV*. Processing information If the alarm is set before the start-up of the distributed part of the alarm system, this field displays LIB. Note that this kind of alarm does not stay as an active alarm and therefore it has no cancel printout. Consecutive number Failure printouts (***, **, *) are numbered in ascending order. With the help of the number you can follow the update and cancel printouts of the original failure printout. R T K (1...64) (A...Z) (001..255)

16. Alarm number An unambiguous identifier for the alarm. It is also a search index for the description of the alarm. 17. Alarm text A short description of the alarm. 18. Supplementary information fields A maximum of 32 fields which are separated from one another by one or several spaces. The following are possible values of the field: - a hexadecimal number (for example 0120) - a decimal number (for example 120d) - a BCD coded number (for example 0120) 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 (for example ALHISTGX) - a functional unit (for example OMU) - a plug-in unit (for example HWAT) - a working state of a unit (for example WO-EX) - a date (for example 1995-06-27) - a time (for example 10:21:42.19) - an IPv4 address (for example 131.255.0.12) - an IPv6 address (for example 1080:0:FE:0:0:255:34:FFFF) In addition, the value of a certain field (for example, the index of functional unit or the index of plug-in unit) can be displayed as two dots (..). This refers to a case where there is no single value to be given to the field according to its meaning. In fault situations there is a question mark (?) printed at the end of the fields. 19. Supplementary text A more detailed text printed out in some alarms. 20. Alarm operating instructions You can define an operating instruction for an alarm by using the MML command AOA. If the instruction has been defined, it is displayed in the alarm printout. Example of a DX 200 alarm printout An example of an alarm printout and the corresponding section in the alarm reference documentation are presented below.

Section from the alarm reference documentation:
2761 CLAB FAILURE MEANING The CLAB plug-in unit is faulty. Either the CLAB does not respond to the supervision messages sent to it by the

control computer, or the software of the CLAB has detected a fault in its interfaces, in the RAM of the plug-in unit, in the phase-locked loop, in the power supply, in the changeover signal or in the basic timing bus interface of the CLAB, or the check sum of the program memory of the CLAB has changed, or a fault has been or the value of the cabling delay measured by CLAB has changed. When the alarm is on the CLAB does not function or its functioning is unreliable.

INSTRUCTIONS

Check the cabling of the cartridge, see Equipment list for cables, Site documents. If there is nothing wrong with the cabling, the fault is likely to be in the plug-in unit. Replace the faulty plug-in unit, see Instructions for Replacing Plug-in Units. If, according to the first supplementary information field, the fault is detected in the basic timing bus interface of the CLAB, and replacing the CLAB, which is the object unit of the alarm, does not remove the alarm, replace the standby CLAB. As a result of the alarm, the recovery system starts the fault diagnosis program which generates a diagnosis report in which a description of the fault related to the alarm is output. The alarm supports the activation of the automatic recovery for the object unit. You can check the supporting amount of the alarm with the MML command ARO.

CANCELLING

Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected.
