Configuring nodes
Access Manager 2000 User Manual 5 -31
The valid range is 0 to 255, with the default set to 10. Modems are limited
to 1 to 15 attempts.
If a path’s attempts are set at 0, then the alarm is sent as many times as
necessar , until it’s delivered. In other words, think of
0 as “no
permission to give up”. If the attempts are set to 4 , then only four
attempts will be made to deliver the alarm along that path.
Pacing delivery of new alarms
To pace the delivery of new alarms, you can specify a Wait Time . The
wait interval is defined, simply enough, as the amount of time to wait
before sending new alarms.
When the first alarm is received, a timer is started with the time specified
in this field. No alarms are sent to the Access Manager until the timer
expires. This allows the node controller to collect (or “buffer”) as many
alarms as possible before establishing the connection to Access Manager
to deliver alarms. If you’re already accessing to the node controller, either
through the Configuration or On-Line Access menus, the wait time will
be ignored and you’ll be sent the alarms as they come up.
This is especially useful when you’re using a modem setup. It enables
you to reduce the number of connections made (and telephone call
charges incurred) when delivering single alarm messages.
To set the amount of time between attempts, go to the Wait Time field,
and type in a time period in one of the following formats. The possible
values include:
• 1 to 59 SEC
• 1 to 59 MIN
• 1 to 24 HR
The default value is 15 SEC for each path.
Resending undelivered alarms
There are times when your alarm will not be delivered on the first
attempt. For example, if you’re using a modem, maybe the line was busy
at the other end.
You can specify the time period before trying again if an alarm delivery
was unsuccessful.
