The number of nodes that can report to a collecting node depends on the number of
connections that can exist on the collecting node. (An FRM supports up to 512 con-
nections per RLP.) A connection on a collecting node is required for each reporting
device.
Do not configure a collecting node to send its alarms to another
collecting node. The alarms will be ignored, due to a format mis-
match.
Max Congestion
is a percentage of the FRM alarm buffer. If this level is exceeded, no more alarms will
be put into the buffer until it has reached the specified
Min Congestion
. (See that entry
below and "
Alarm Buffer
" on page 21-2.)
Min Congestion
is a percentage of the FRM alarm buffer. As long as the percent of the buffer that is
full is below this level, alarms will always be placed into the buffer. (See "
Alarm
Buffer
" on page 21-2.)
Periodic Status Timer
sets the frequency with which the FRM will send a "heartbeat" alarm message con-
taining the date and time. The heartbeat serves as a verification that the FRM is oper-
ational.
Line Idle Timer
is a period that an SVC alarm connection will remain active after an alarm message is
sent. If no alarm is generated during this time, the alarm connection is cleared. The
Periodic Status Timer
(see that entry) determines the frequency with which routine
status messages for this FRM will be sent. On a reporting (non-collecting) node, it is
generally preferable to set the
Line Idle Timer
to a period longer than the
Periodic Status
Timer
, to give the system a chance to update itself. The timer is usually set to
0
on a
collecting node.
The
Line Idle Timer
is also affected by the value of
Max Congestion
.
Alarm Autocall Timer
specifies the frequency with which the FRM will attempt to establish an alarm con-
nection with its
Primary Alarm Output ID
during initial call setup or after the previous
alarm connection is cleared.
Alarm Max Retries
is the number of times the FRM will attempt to establish an alarm connection with its
Primary Alarm Output ID
during initial call setup or after the previous alarm connection
is cleared.
If the value specified is greater than
0
, the
Alarm Autocall Timer
will be used until the
maximum retry value is reached. If the connection is still not established, a retry will
be made once every hour.
