LANTime NTP/SNTP Server
Meinberg LANTIME Time Servers will synchronize all NTP or SNTP compatible systems and utilize a Meinberg Timing Reference as the precision time source. A highly stable internal oscillator bridges periods of interference or temporary loss of synchronization with minimal loss of accuracy. Models are available in DIN railmount, and 1U and 3U desktop or rackmount chassis which can include displays, broadcast reference time sources, precision internal oscillators, and multiple Ethernet ports, frequency, or pulse outputs.
Key Features of all LANTIME units:
- Synchronization of NTP and SNTP compatible clients.
- Web based status and configuration interface and console based graphical configuration utility.
- Supported networking protocols: IPv4, IPv6, HTTPS, HTTP, SSH, TELNET, SCP, SFTP, FTP, SYSLOG, SNMP.
- Alert-Notification system of status change by email, WinMail, SNMP or an externally connected display.
- Full SNMP v1,v2,v3 support with own SNMP-daemon for status, configuration, and SNMP trap messages.
- RJ-45 10/100 MBit Ethernet interface.
- USB port to perform updates, lock front panel, and backup or restore configuration and log files.
System Description:
To support network management systems, LANTIME Time Servers offer an extensive SNMP interface, which can be accessed by SNMP V1, V2.c and V3. This allows monitoring of all relevant system parameters (including operating system parameters, network interface statistics, detailed Receiver and NTP status information, and complete system configuration) and can also be used to alter the LANTIME configuration via SNMP set commands.
LANTIME Time Servers are designed to be deployed in IPv6 networks, and the NTP time synchronization and configuration interfaces (Web-based, SSH and SNMP) include IPv6 support. You can assign several IPv6 addresses, and the system supports automatic configuration by IPv6 autoconf.
The GNU/Linux operating system of the LANTIME's Single Board Computer (SBC) has been optimized to ensure a high level of reliability, and the security-related features of the LANTIME satisfy the highest security demands. Time synchronization data can be reliably signed and secured by symmetric keys (MD5) and the NTP autokey procedures. This protects clients against manipulated time and man-in-the-middle attacks and verifies that the NTP packets they received were sent by the LANTIME. Additionally, the entire LANTIME can be configured using encrypted SSH, HTTPS or SNMPv3 channels. Each unused or unneeded protocol can be disabled in order to reduce possible points of attack.
Configuration of the system is accomplished using a standard web browser to access an extensive and straightforward html interface. Alternatively, a text based and menu driven setup utility can be initiated at the shell prompt after logging onto the unit via Telnet or SSH.
Three bi-color LEDs indicate the status of the three main components: Reference Time (integral Receiver), Time Service (NTP), and Network (Link status). A fourth Alarm LED can be configured by the user to signal any event that is supported by the notification routines, which can also provide alarm notification via email (SMTP), SNMP traps, Windows Popup Messages and syslog.
LANTIME Time Servers are equipped with a TCXO high precision oscillator as the standard internal oscillator. The accuracy of the internal oscillator determines the holdover characteristics when the reference time signal is disturbed or unavailable, and for applications with higher accuracy requirements there are several oscillator options available (see "oscillator options" for detailed specifications about oscillator upgrades).
Because of the modular system architecture it is possible to equip a LANTIME Time Server with a number of different reference time sources. More sophisticated systems can be configured by combining multiple time sources and redundant power supplies. Output options include additional network or serial ports, serial string configurations, and frequency and pulse outputs.
