RTC Parameters
What’s this?
• The gateway supports various features (like CDR etc.) which use
current date and time parameters. Such facilities work properly only
if the Gateway is set with correct date and time value, using Real
Time Clock (RTC) feature.
• The gateway also uses SNTP (Simple network Time Protocol) for
network time. It ensures accurate local time keeping with reference
to radio and atomic clocks located on the internet.
How it works?
• The Gateway has its own RTC. Thus, RTC parameters can be
programmed through Web Jeeves.
• It also uses the Network time to update the RTC. For this you can
program the Time Server.
• The system makes use of SNTP (Simple network Time Protocol) to
get time from the Time Server.
• The gateway supports following three Time Servers:
• Ntp1.cs.wisc.edu
• Time.windows.com
• Time.nist.gov
• User can select any one option among three to obtain the date and
time or may enter his own choice.
GMT Time (Greenwich Mean Time):
• These servers give GMT times. Hence time has to be adjusted as
per the time zone selected by the user (depending the country you
are working) and use the time for displaying and storing the date,
time and duration of each call.
• The VFX88L
/
VFX44L gets synchronized with the specified NTP
server (IP Address), which is a global server and gets the date and
global time. Based on the time zone, settings, Matrix
VFX88L
/
VFX44L shows correct time for that country.
For example:
• If time shown by ntp1.cs.wisc.edu server for India (Culcutta,
Chennai, Mumbai, New Delhi) is 10:44:50AM, then current time
