Alarm Configuration
8.9. 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.
