3.1.2 Condition Code Types
There are three types of conditions that are reported by the FLM 150 ADM—
alarm conditions, transient conditions, and standing conditions. These conditions
are defined as follows:
• Alarm conditions trigger autonomous messages to notify maintenance
and operational personnel of failure or fault conditions that require
immediate response. Autonomous alarm condition messages carry an
ALMEVT label. In addition, office alarms alert local maintenance
personnel with audible and visible indications that an alarm condition
exists. Alarm conditions can also be reported to a remote operations
support system (OSS). Alarm messages can also be retrieved via the craft
terminal with the RTRV-ALM-ALL command or from FLEXR by clicking
in the Alarm Summary window.
• Transient condition messages provide a record of events that are
momentary. These may or may not be associated with an alarm event.
Autonomous transient condition messages carry an EVTTC label. The two
categories are:
- Notification of threshold crossings of performance monitoring (PM)
- Notification of switches between working and protection equipment.
• Standing conditions result from a manual operation, such as a manual
switch, loopback, mismounted cards, or the use of the internal test signal
capability of the network element (NE). The condition remains present
until the manual action that created the condition is released. Many
standing conditions are accompanied by the alarm condition MAN, which
stays active until the manual switch, loopback, or signal injection is
released. Standing conditions trigger autonomous messages that carry an
EVTSC label. A standing condition message can be retrieved with the
RTRV-COND-ALL command.
