Max Congestion
is a percentage of the FRX/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" page 18-2.)
Min Congestion
is a percentage of the FRX/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 18-2.)
Periodic Status Timer
sets the frequency with which the FRX/FRM will send a "heartbeat" alarm message
containing the date and time. The heartbeat serves as a verification that the FRX/FRM
is operational.
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 FRX/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
(described on page
3-8).
Alarm Autocall Timer
specifies the frequency with which the FRX/FRM will attempt to establish an alarm
connection with its
Primary Alarm Output ID
during initial call setup or after the pre-
vious alarm connection is cleared.
Alarm Max Retries
is the number of times the FRX/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.
On-Line Temporary Changes
determines whether changes made will affect the
Database
or
System Memory
values
(
Database
values exist in the software, and are recorded as
System Memory
values
when the FRX/FRM is booted.) If
On-Line Temporary Changes
is set to
N
, the
Database
value will change. If
Y
, the
System Memory
value will change. Pressing
[F7]
after
changing either set of values will propagate the change to the other set. (This must be
done at each screen, and affects only those parameters on that screen.)
