LANTIME M200 time servers can be installed to provide accurate time to small and medium sized computer networks.

This entry level time server synchronizes all systems either NTP- or SNTP-compatible utilizing a built-in Meinberg WWVB radio clock as its primary reference time source. The WWVB receiver decodes the WWVB long wave radio signal and is capable of bridging interferences or a temporary loss of reception.

The LANTIME M200/WWVB includes a reference clock (WWVB long wave signal), a single-board computer SBC LX800 500 MHz with integrated network card, and a power supply unit, all installed in a metal desktop case and ready to operate.

The interfaces provided by LANTIME are accessible via connectors in the rear panel of the case. Details of the components are described below.

Front View:

1. LC Display (current status and configuration menu)
2. Function buttons for operating the display menus
3. Status LEDs: Ref. Time (Status of reference clock), Time Service (status of NTP
service), Network (link status of network interface) and a configurable Alarm LED
4. optional brackets for rack mount installations

Rear View:

1. Power supply unit with power switch
2. Network interface (10/100base-T RJ45)
3. USB port for firmware updates and backup/restore of configuration files
4. Serial console port for configuration (RS232, set your terminal program to 38400 baud, 8/N/1)
5. WWVB antenna input
6. optional brackets for rack mount installations

A large LC display shows the state of the internal WWVB receiver and the NTP subsystem. Three LEDs (green/red) indicate the status of the three main components: Reference Time (WWVB), Time Synchronization Service (NTP) and Network (Link status). A fourth red LED is labelled ALARM and can be configured to signal any event that is covered by the notification handling routines.

The configuration of the system can be done by using a standard web browser for accessing 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.
