LANTIME M400/GPS DIN-Rail mounted Reference Clock for Industrial Applications
Description
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.
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.
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).
