The Tempus LX is a Stratum 1 NTP Time Server that provides an accurate, reliable and secure source
of network time inside your firewall. This model uses CDMA as its time synchronization source so
you can mount the indoor antenna on top of your equipment rack or anywhere you can receive
a CDMA cell phone signal. No cell phone subscription required!
- Supports 200,000 network clients with <10 microsecond NTP timestamp accuracy.
- CDMA synchronization allows you to locate antenna inside building. Magnetic-mount antenna has 12 feet of cable.
- User-friendly display & keypad with built-in help menus.
- NTP, SNTP, HTTPS (Web Interface), SNMP, SSH, SCP, MD5, TIME, DAYTIME, TELNET, FTP, DHCP and more.
- IPv4 and IPv6 compliant.
- Superior reliability - an MTBF of 25 years based on demonstrated field data.
- Options: Oscillator Upgrades, Alarm, Timecode, 1PPS, Pulse Rates, Sysplex, -48Vdc,
PTP/IEEE-1588 Grandmaster, and more.
- No cell phone subscription required.
Easy & Safe to Install
Most Stratum 1 NTP Time Servers require an antenna that must be installed on the roof of your building,
with good sky visibility. The Tempus LX eliminates this problem by synchronizing to signals
broadcast from the CDMA mobile cellular/PCS telephone system.
You can install the antenna wherever the unit is located, even
deep inside buildings, and still have an NTP server that is as stable and accurate as with GPS.
And, by installing the antenna safely inside, the
Tempus LX eliminates any risk of damage to your equipment rack caused by lightning strikes.

Web Interface
Status monitoring can be easily accomplished by pointing your web browser to the Tempus LX. Here is an example
of one of the status pages. You can also perform software upgrades with the Web Interface.
For security-conscious users, HTTPS can be completely disabled.
Network Security Hardened
Extra care has been taken with the Tempus LX to "harden" it against network attacks.
There are only a small handful of settings that need to be made and they typically
need to be set only once in the lifetime of the product. Since this is a set-it-and-forget-it
box we have eliminated all extraneous protocols/services in order to minimize
exposure to security holes. You can change critical settings via SSH or Telnet and monitor the alarm/status
information by using HTTPS, SNMP, SSH or Telnet. Security-conscious
users can disable any of the risky protocols or restrict access to specific hosts.
Oscillator Upgrade Options
Exclusive EndRun oscillator-control algorithms provide extended Stratum 1 holdover performance if
the unit is not locked to the CDMA synchronization signal. NTP Stratum 1 holdover periods are:
