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.

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

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,

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.

The description of each alarm is started on a new page in the Alarm Reference Manual. The description always contains the following parts: 1. Alarm number: Decimal number on the upper right hand corner of the page. 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 16 from left to right. 5. Instructions: There are instructions for all failure and diagnosis reports with urgency level ** or ***. 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. 6. Cancelling: Information on whether the user should cancel the alarm or whether the system does it after the fault situation is over.

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. 19.

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

failure specification: 00 01 02 03 04 05 06 07 08 09 0A 2 CLAB does not respond to supervision messages failure detected in interface testing check sum of program memory changed fault in RAM configuration contradiction (HCLTBL - SCDFLE) fault detected in phase-locked loop fault in 5V power supply fault detected by hardware fault in field changeover signal fault in the basic timing bus interface of the CLAB cabling delay measured by CLAB has changed
number of SBUS; in use only when the value of supplementary information field 1 is 00 00 01 02 CLAB is not responding to supervision messages on SBUS-0 CLAB is not responding to supervision messages on SBUS-1 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,

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.
