LANTIME M300/WWVB : NTP Time Server with integrated WWVB Radio Clock

Image Zoom
The Meinberg LANTIME M300/WWVB time server can be used in large parts of the USA, Canada and the Central America region to provide accurate time to networks of any size. It synchronizes all systems either NTP- or SNTP-compatible and uses a built-in Meinberg radio clock receiving the WWVB time signal from Fort Collins,CO 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.
• 60KHz Antenna (cable length up to 300m)
• 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 LANTIME M300/WWVB is equipped with a high precision oscillator "TCXO" (look at oscillator options for details) as standard. The oscillator determines the holdover characteristics (e.g. when the WWVB radio signal is disturbed or jammed). For applications with higher accuracy requirements other oscillator options are available.

A large display shows the state of the internal WWVB long wave receiver and the NTP subsystem.

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 WWVB 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 four additional ethernet ports.
