1 Introduction
The Alarm Reference Manuals of the DX 200 system are intended for
maintenance personnel working with DX 200 exchanges. They describe the
alarms and diagnosis reports printed out on a terminal device and contain, when
necessary, instructions for corrective maintenance actions.
The manuals contain the alarms of all DX 200 applications, and it is possible,
therefore, that they also include alarms that do not belong to the configuration of
a particular customer.
The user of this manual is assumed to have taken the DX 200 system course and
the operation and maintenance course.
Additional information can be found in document Alarm Administration,
Maintenance Manual.

O&M equipment 2800 - 2899, 3800–3899
transmission equipment 2900 - 2999, 3900–3999
Diagnosis reports (DIAGN):
diagnosis report number
3700 - 3999
The following numbers have been reserved for possible external alarms:
alarm number
switching equipment 4000 - 4799
O&M equipment 4800 - 4899
transmission equipment 4900 - 4999
power equipment 5000 - 5499

9. Alarm object
The functional unit which is the object of the alarm.
If the object of the alarm is not a functional unit, the field displays eight
dots (.).
10. Position coordinates of alarm objects
Position coordinates are expressed in the form RTK-V, where:
R (1...64) is the rack row
T (A...Z) is the rack
K (001..255) 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 ??????-??
11. Alarm issuer
The program block issuing the alarm.
12. Trial information
If the exchange has been divided into a traffic transmitting part and a trial
configuration, this field displays the text TRIAL if the alarm originated in
the trial configuration.

help of the number the user can follow the update and cancel printouts of
the original failure printout.
16. Alarm number
Alarm number is a search index in the alarm reference manual.
17. Text
The text is a short description of the alarm.
18. Supplementary information fields
A maximum of 16 fields which are separated from one another by one or
several spaces. The following are possible values of the field:
- a hexadecimal (e.g. 0120)
- a decimal (e.g. 120d)
- a BCD code (e.g. 0120)
If the number is BCD coded, it is mentioned in the alarm
reference manual in the explanations of the field in question
- a single character or characters (e.g. ALHISTGX)
- a functional unit (e.g. OMU)
- a plug-in unit (e.g. HWAT)
- a working state of a unit (e.g. WO-EX)
- a date (e.g. 1995-06-27)
- a time (e.g. 10:21:42.19)
In addition, the value of a certain field (e.g. 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.

Page from the alarm reference manual:
2761
CLAB FAILURE
MEANING The CLAB plug-in unit is faulty. Either the plug-in unit 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, the check sum of the program memory
of the CLAB has changed, or a fault has been detected in the
RAM, the phase-locked loop, the power supply, changeover
signal of the plug-in unit, the basic timing bus interface of
the CLAB, or the value of the cabling delay measured by CLAB
has changed.
SUPPLEMENTARY
INFORMATION
FIELDS 1 failure specification:
00 CLAB does not respond to supervision messages
01 failure detected in interface testing
02 check sum of program memory changed
03 fault in RAM
04 configuration contradiction (HCLTBL - SCDFLE)
05 fault detected in phase-locked loop
06 fault in 5V power supply
07 fault detected by hardware
08 fault in field changeover signal
09 fault in the basic timing bus interface of the CLAB
0A cabling delay measured by CLAB has changed
2 number of SBUS; in use only when the value of
supplementary information field 1 is 00
00 CLAB is not responding to supervision messages
on SBUS-0
01 CLAB is not responding to supervision messages
on SBUS-1
02 CLAB is not responding to supervision messages
on either bus
INSTRUCTIONS Replace the faulty plug-in unit, see Instructions for
Replacing Plug-in Units, Maintenance Manual.
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 does not remove the alarm,
replace the standby CLAB.
If, according to the first supplementary information field,
the value of cabling delay measured by CLAB has changed,
Alarm printout

and replacing the CLAB does not remove the alarm, check
the cabling.
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.
