External Alarms
Preconditions and initiation
The external alarms function is started by the restart and recovery
function.
Description
The following parameters are associated with each supervised external
alarm:
Inlet Number 1–16. Defines which inlet the external
alarm source equipment is connected to.
Inlet Usage "Auxiliary Fault", "External Alarm" or
"Not Defined". The default alarm setup is
that alarm inlets are "Not Defined".
Alarm Identity The numeric identity of a specific external
alarm within the RBS.
Alarm Severity There are two possible severity
classifications, "Level 1" or "Level 2".
The classification of a specific external
alarm is fixed when defining the external
alarm. How to handle a severity level is
customer-defined.
Alarm Data An alphanumeric string which is presented
to the operator when the external alarm is
raised. The basic character set , that is
presented in Concepts, should be used.
The alphanumeric string associated with
each external alarm may contain a
maximum of 62 characters.
Fault Activation Criteria The way in which the external alarm is
activated, either by breaking or closing the
circuit on the external alarm inlet.
The RBS supervises each configured external alarm. An external alarm
is filtered, i.e. must remain in a state for a fixed period of time
(approximately 3 seconds) before the BSC is notified of the external
alarm raising or termination.
The raising or termination of each external alarm is reported to the BSC
with the associated Alarm identity, Alarm severity and Alarm data.
To determine which external alarms are raised, the BSC can request this
information from the RBS via A-bis.
43.4 Operation and Maintenance
Purpose
Maintenance functions related to external alarms are described within
the context of Operation and Maintenance Terminal.
The visual indicators relevant to external alarms are described within
the context of Operation and Maintenance Support.
