LANTIME M400/GPS/PTP: PTPv2 / IEEE 1588-2008 Grandmaster Clock and NTP Time Server with integrated GPS radio clock

Network Time Server with GPS Reference Clock for Industrial Applications
The LANTIME M400/GPS/PTPv2 Time Server offers an unparalleled flexibility and versatility and provides accurate time to your network in a compact and full-featured DIN railmount package for industrial applications such as process control and industrial automation systems. The LANTIME M400 includes an LC-Display and keypad and an extremely broad range of available options.

The M400/GPS/PTPv2 synchronizes all PTPv2 / IEEE 1588-2008 compatible clients and 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.

Product Description

Being a very stable IEEE 1588-2008 Grandmaster clock, the LANTIME M400/GPS/PTPv2 not only provides a highly accurate source of synchronization for PTP clients ("slaves" like the PTP270PEX), it additionally introduces the absolute time ("current time of day") to your PTP networks.

The PTP V2 multicast implementation of the LANTIME is fully compliant to the IEEE 1588-2008 standard and therefore provides PTP management messages as well.

The LANTIME M400/GPS/PTPv2 is available with GPS or an combined GPS / GLONASS receiver and can be customized with a lot of different options to deliver exactly the feature set that is required for a certain application/environment.

The ultra compact form factor enables this product to become the ideal time and frequency source in installations where every millimeter counts. It is available in two different sizes: the standard M400 chassis (105x189x146mm) with one option slot and the XL version (105x189x166mm) that offers an additional slot to provide even more outputs and interfaces. With up to 5 (M400) and up to 9 (nine!) Ethernet ports, this NTP appliance offers the world's highest port densitiy.

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

As with most LANTIME M-Series models, a large LC-Display showing the state of the internal GPS receiver and the NTP/PTP subsystem is combined with three bicolor LEDs (green/red) that indicate the status of the three main components: Reference Time (GPS), Time Synchronization Service (NTP/PTP) 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.

In order to configure the system, an extensive but straightforward html interface can be accessed with any HTML compatible browser. A text based and menu driven setup utility can alternatively be started from the shell prompt logging in to the unit via a serial console port, 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.

Integrating LANTIME time servers into an existing network management system is easy, due to the extensive SNMP interface, supporting SNMP versions V1, V2.c and V3. Besides the monitoring of all relevant system parameters (including operating system parameters, network interface statistics), it offers read-only access to detailed GPS and NTP status information and can be set up to allow to authenticated systems read-write access to the complete system configuration. In order to allow automatic/scripted recovery and control, a number of system functions are available via SNMP, too (e.g. rebooting the system).

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.

The LANTIME M400 GPS is equipped with a high precision oscillator "OCXO HQ" (look at oscillator options for details). The oscillator determines the holdover characteristics (e.g. when a reference source signal like GPS is disturbed or jammed). For applications with higher stability/holdover requirements the "OCXO DHQ" oscillator option is available. You can choose this oscillator together with the XL housing type.

Because of its modular system architecture it is possible to equip a LANTIME M400 time server with a number of different reference time sources. Optionally several additional frequency-, serial string- and pulse outputs are available as well as power supplies for additional input voltage ranges.

In addition to the standard electrical interfaces a lot of output signals can be delivered on optical ports, too.
