Alarm Configuration
7.8. The No Dialtone Alarm
The No Dialtone Alarm enables the RPC to monitor a telephone line connected to an
external modem installed at the RPC Console Port, and then provide notification if the
RPC detects that the phone line is dead or no dialtone is present.
If the No Dialtone Alarm is enabled and the RPC determines that there is no dialtone
signal, the No Dialtone Alarm can provide notification via email using a network
connection. In the event that the RPC unit is not connected to a network cable, the RPC
will also create an entry in the Alarm Log, indicating that the No Dialtone Alarm has been
triggered.
Notes:
• In order for this alarm to function, the No Dialtone Alarm parameter in the
Serial Port Configuration menu must first be configured and enabled as
described in Section 5.8.
• In order for the RPC to provide alarm notification via Email, communication
parameters must first be defined as described in Section 5.9.11.
• In order for the RPC to provide alarm notification via Syslog Message, Syslog
parameters must first be defined and Syslog Messages must be enabled as
described in Section 5.9.2 and Section 11.
• In order for the RPC to provide alarm notification via SNMP Trap, SNMP
parameters must first be defined, and SNMP Traps must be enabled as
described in Section 5.9.7 and Section 12.
The configuration menu for the No Dialtone Alarm allows the following parameters to be
defined:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On)
Note:
• When an alarm is generated, to cancel an alarm without correcting the
condition that caused the alarm, simply toggle the Trigger Enable parameter
Off and then back On again.
• The Trigger Enable, Notify Upon Clear, Email Message and Address 1, 2
and 3 Parameters all include "Copy to All Triggers" options that allow you
to enable/disable the corresponding parameter for all RPC alarms. For
example, if the No Dialtone Alarm's Trigger Enable parameter is set to "On
(Copy to All Triggers), then all other RPC alarms will also be enabled.
• ResendDelay: Determines how long the RPC will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes)
