Time Server NTP
- Getting Started
Time Server NTP provides
exact time directly to the
LAN (WAN). It can
simultaneously synchronize
the time of all servers,
workstations and CISCO
routers operating in TCP/IP
networks under the NTP (Network
Time Protocol). The time
source is the GPS (satellite
signal), DCF77 (radio AM FM
long waves) or the rubidium
(cesium) oscillators. The
devices work with most of
the popular operating
systems including Windows
95/98/ME/NT/2K/XP and all
Unix-based systems. All
timeservers NTP are STRATUM
1. All internal NTP
timserver time sources (GPS,
DCF77, rubidium, cesium) are
STRATUM 0.
GPS and DCF77 Radio Clocks
provide the exact time via
the RS232 interface to the
PC. They are used in the
absence of LAN or whenever
the use of NTP is impossible
or unjustified. GPS and
DCF77 Radio Clocks (connected
to PC operating under NTP
timeserver software) are
STRATUM 0.
Elproma NTS-3000 simple GPS time server
The high precision UTC
time is powered by cesium atomic clocks via GPS (Global Positioning
System) satellite system. The NTS–3000 distributes UTC reference time to 2 (3* -
extra option) isolated Ethernet 10/100Mbs subnetworks. All information is traced on front
panel LCD display as well as it can be monitored over network using
software: standard NTP utilities
ntpq,ntpdc
, WWW service (supporting web browser), TELNET, SSH, SNMP etc.
Elproma NTS-4000 time backup from OCXO
OCXO oscuillator improves safety of time
synchronization over network. The NTS-4000 time server can work independently to
GPS and other sat's time patterns. This is one of the ways to set Time Failed
Tolerance network.
Elproma NTS-5000 RUBIDIUM the real atomic performace
Built-in
double oscillators RUBIDIUM and OCXO guarantee correct time
keeping up to one year of work when both antennas are missing. A true novelty is
an option to create cascade NTS servers where one can simulate an 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.
Elproma NTS-dialup modular NTP server
It collects reference UTC time
form public telephone services or official time NTP servers available on the
Internet. For such purposes, NTS-dialup can be equipped with analogue PSTN,
digital ISDN and GSM/GPRS/EDGE modems. Optionally, NTS-dialup can be delivered
with its own single satellite GPS receiver or DCF77 radio long wave
receiver.
