NTS Product Overview NTSxxxx provides a high
precision time directly to TCP/IP networks using
NTP (Network Time Protocol RFC 1305) and SNTP
(Simple NTP RFC 2030). Itsynchronizes time of any
NTP or SNTP clients running on remote PCs,
thousands of servers, workstations and routers,
including all CISCO products. The time source
supported includes GPS (satellite signal), and/or
DCF77 (radio AM FM long waves). Any NTS can
support up to 2 independent GPS antennas. Other
systems like GPS, Glonass, Galileo are
supported on request. The double frequency
technology L1/L2 is availbale on request.
Built-in oscillators (OCXO, RUBIDIUM) guarantee
correct time keeping up to one year of work
when both antennas are missing.
12
A true novelty is an option to create cascade NTS
servers where one can simulate an GPS antenna
for the other. This functionality enables time
synchronisation of secured LANs with official
time NTP servers available publicly online in
Internet and the development of secured LAN
systems for remote time auditing and control.

13
Remote time auditing. This solution requires 2x
NTS servers working together.

14
The NTS-3000/4000/5000 is ideally suited for
delivering system-wide for financial
institutions, network security and e-commerce.
It is possible to use several NTS units
simultaneously. All unit can work independently
or in primary/backup mode (NTP peer). It
supports popular operation systems
including Windows Mac OS/X Linux, Free BSD,
NetBSD, OpenBSD HP-UX IBM AIX, IBM AS/400 Sun
Solaris Unix others and many others
