TIME SOURCE
SNTP
Simple Network Time Protocol (SNTP) is a protocol for synchronization of clocks of computer
systems (ViPRs) over the Internet. When SNTP client is enabled the ViPR will poll the time
server for the time information update.

ALARM REPORTING
The ViPR radio can be enabled to report several different types of alarms using the SNMP
protocol. If SNMP is enabled (Setup (Advanced) – IP Services) and reporting is enabled for
a specific alarm, the ViPR will send an SNMP Trap to each of the IP addresses listed in the
Trap IP List (Setup (Advanced) – IP Services) whenever an alarm occurs.
If the condition that caused the alarm clears, the ViPR will send a second SNMP Trap to each
of the IP addresses listed in the Trap IP List, indicating that the error has cleared.
Forward Power Alarm & Notification
The Forward Power Alarm will trigger when the measured forward power drops 1 dB or more
below the user configured transmit power. The Forward Power Alarm SNMP trap is
generated when this condition occurs. When the forward power returns to within 0.8 dB of
the wanted power the error is cleared and a second notification is sent indicating the error
has cleared.
For example, assume the ViPR is programmed to transmit at 10W. If the measured forward
power drops below 7.9W then the error is detected and the SNMP Trap or Alarm is
