Message Introduction [1]; Alarm Indications [2]; Customer-Selected Alarm Levels [3]; Other Alarm Indications [4] - Northern Telecom DMS-100 Series Maintenance Manual

[1] Message introduction
The first area contains the message format as it would appear at the system
maintenance terminal, or equivalent. To the extreme right of the message
line is the applicable DPP system version(s) of the message. The DPP
system version is identified as either BCS25, BCS26, or so forth.
Immediately following the message output format is a description of any
variable (numeric) field data. This data is depicted by lower case letters,
such as, xx or yy.
The first area ends with a brief description of the condition which caused the
message to appear.
[2] Alarm indications
Alarm levels, if any, associated with the message appear in this area. The
first entry shows the action the DPP system automatically takes
due to the condition or situation which caused the message. Such actions
could include a processor switch, session terminated, disk drive system
made non-redundant, or N/A (Not Applicable).
Messages which do not produce an error (alarm) indication are also
identified in this area. Such messages are response messages and
information-only messages. For these messages, monitor the frequency of
occurrence (repetition) over a period of time before taking corrective action.
If there is a corresponding ERRMAP (Error Map) entry for the (log
message), the entry appears in this area. Refer to Error Indicators,
ERRMAP (Error Map) Command for information on the Error Map and on
using the ERRMAP commands.
The system default levels shown are those defined at start-up time, before
specific site data have been entered.
[3] Customer-selected alarm levels
This user completes this area and should make appropriate entries in the
space(s) provided to reflect the 3-level alarm (assignments) structure he

[4] Other alarm indications
This area is for noting what type, if any, audible and/or visual alarms are
provided. This area also provides a section for the user to reflect the 3-level
alarm (assignments) structure he established at the site. Since this structure
is user-selectable and changeable, record these entries with an erasable
marker.
