6.11 Alarms and Alarm Configuration
6.11.1 Overview
The MirrorCell Select CDMA repeater can send alarms to an Operations and
Maintenance Center or to the MirrorCell Element Manager (MEM), both referred to as the
OMC in this document, via a DataCall (modem connection). For each alarm sent, an end
of alarm will also be sent when the end of alarm condition is detected. This does not
include VLI, LGO, CLR, and ILI alarms. By default, the repeater requires an
acknowledgement of each alarm sent. When using SMS, all letters must be capitalized.
Each alarm source can be individually configured. The software has the capability to
enable or disable the requirement to acknowledge particular alarms (not including VLI,
LGO, CLR, and ILI alarms), and the capability to configure different threshold for
particular alarms. In addition, if a particular alarm condition arises which causes the alarm
to toggle between OK and ERROR, the software has the capability to adjust the Minimum
Alarm Repetition (MAR) time and the Maximum Number of Repetitions (MNR). This will
keep the repeater from blocking the communication interface with a series of Alarm/End
of Alarm notifications. (See section 6.11.7.2, “Minimum Alarm Repetition Time” for more
information on this feature.)
