Tempus LX CDMA Network Time Server
Our Full-Featured CDMA Time Server
Provides Accurate and Reliable Network Time Inside Your Firewall
|
|
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.
It includes a proprietary CDMA receiver which allows you
to locate the antenna anywhere you can receive a cell phone signal. This saves you the trouble
and expense of installing a rooftop antenna which is a typical requirement for most other network time servers.
- Supports 200,000 network clients with <10 microsecond NTP timestamp accuracy.
- CDMA synchronization allows you to locate antenna inside building.
- User-friendly display & keypad with built-in help menus.
- NTP, SNTP, MD5, SNMP, SSH, SCP, 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, Pulse Rates, Sysplex, -48Vdc.
- 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.
In addition, by installing the small cellular antenna safely within the confines of your building, the
Tempus LX virtually eliminates any risk of damage to your equipment rack caused by lightning strikes.

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 SSH, Telnet, or SNMP. Security-conscious
users can disable any or all of the risky protocols such as Telnet, Time and Daytime or restrict
access to SSH, Telnet and SNMP to specific hosts.
Oscillator Upgrade Options
Exclusive EndRun oscillator-control algorithms provide extended Stratum 1 holdover performance when
the unit is not locked to the synchronization signal. NTP Stratum 1 holdover periods are:
|
| TCXO |
10 milliseconds for 1st day |
24 hours |
| OCXO |
100 microseconds for 1st day |
35 days |
| Rubidium |
8 microseconds for 1st day |
140 days |
