LANTIME/GPS/xHS : NTP Time Server with integrated GPS radio clock in railmount housing

Image Zoom		The compact Meinberg LANTIME/GPS/AHS time server is used around the world to provide accurate time to networks of any size. It synchronizes all systems either NTP- or SNTP-compatible and uses a built-in Meinberg GPS radio clock as its reference time source. A highly stable and precise oscillator is capable of bridging interferences or a temporary loss of reception.

Key Features

Synchronization of NTP and SNTP compatible clients
Web based status and configuration interface (Demo) and console based graphical configuration utility
Supported net protocols: IPv4, IPv6, NTP, SNTP, DAYTIME, DHCP, HTTP, HTTPS, FTP, SAMBA, SFTP, SSH, SCP, SYSLOG, SNMP, TIME, TELNET, W32TIME
Alert-Notification system of status change by Email, WinMail, SNMP or an external connected display
Full SNMP v1,v2,v3 support with own SNMP-daemon for status and configuration and SNMP Trap messages
USB port for performing updates, lock front panel, and backup/restore configuration and log files.
Antenna connected with up to 300m of standard coaxial cable RG58
Optional expansions and/or configurations available: Product Options

Description

The GNU/Linux operating system of the LANTIMEs SBC (Single Board Computer) has been optimized to ensure a high level of security and reliability.

The configuration of the system can be done by using a standard web browser to access the extensive but straightforward html interface. Alternatively a text based and menu driven setup utility can be started from the shell prompt after logging into the unit via Telnet or SSH.

The security-related features of LANTIME time servers satisfy highest demands. The time synchronization data can be reliably signed and secured by symmetric keys (MD5) and the NTP autokey procedures. This protects the clients against manipulated time and man-in-the-middle attacks and allows them to verify that the NTP packets they received were send by the LANTIME. Additionally the whole LANTIME configuration can be done by using encrypted channels (e.g. SSH, HTTPS or SNMPv3). Every unused/unneeded protocol can be disabled in order to reduce possible points of attack.

In order to support network management systems the LANTIME time servers offer an extensive SNMP interface, which can be accessed by SNMP V1, V2.c and V3. It allows the monitoring of all relevant system parameters (including operating system parameters, network interface statistics, detailed GPS and NTP status information as well as the complete system configuration) and can be used to alter the LANTIME configuration via SNMP set commands, too.

LANTIME time servers are designed to be deployed in IPv6 networks, the NTP time synchronization as well as the configuration interfaces (Web-based, SSH and SNMP) comes with IPv6 support. You can assign several IPv6 addresses and the system supports automatic configuration by IPv6 autoconf.

Because of its modular system architecture it is possible to equip a LANTIME time server with up to two additional ethernet ports and a number of different reference time sources. Optionally several additional frequency-, serial string- and pulse outputs are available and by combining two (even different) time sources and redundant power supplies, high-availability systems are no problem. Besides that a collection of oscillators, from the reliable temperature controlled base model (TCXO), the three excellent oven controlled variants (OCXO-LQ, -MQ and -HQ) to the high-end rubidium based top model, offers a wide selection of holdover characteristics (e.g. when the GPS signal is disturbed or jammed).

The LANTIME/GPS/xHS can be ordered in three different variants, depending on your required input power range:

LANTIME/GPS/AHS
100-240VAC
(Molex Connector)
LANTIME/GPS/DHS
18-72 VDC
(Phoenix DFK3 Connector)
LANTIME/GPS/DAHS
100-240 VDC
(Phoenix DFK3 Connector)
