6.3.8.3 SNTP (Simple Network Time Protocol)
The SNTP client allows the 45 Mbps Backhaul to obtain accurate date and time updates from a networked
timeserver. The resultant time information is used by the SNMP, webpage and System Reboot tasks.
SNTP State The SNTP state attribute controls the creation of the SNTP features.
SNTP IP Address The IP address of the networked SNTP server.
SNTP Port Number The port number of the networked SNTP server. By convention the default value for the
port number is 123.
SNTP Poll Interval The period at which the SNTP client polls the server for time correction updates. Default 1
hour. If for any reason an SNTP poll fails the client will automatically perform 3 retries before waiting for the
user defined poll period.
SNTP Time Zone The SNTP time zone is a fixed offset from GMT that is added to the correct time to allow the
expression of time in all geographic time zones.

All diagnostics are extracted from the associated status and statistics webpage histograms. They
are translated in a CSV file containing at most 3600 entries that equates to one hours worth of
diagnostics. Each entry is a one second average and the number of sample the 45 Mbps Backhaul
makes in an one second period.
