Description
Being a IEEE 1588 Ordinary clock, the LANTIME/PTP is
synchronized by a PTP/IEEE 1588 Grandmaster clock
(like our LANTIME/PTP/GPS)
and uses this time as a reference for its NTP
subsystem.
The GNU/Linux operating system of the LANTIMEs SBC
(Single Board Computer) has been optimized to ensure
a high level of security and reliability.
A large display shows the state of the PTP
synchronization 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 NTP status
information as well as the complete system
configuration) and can be used to alter the LANTIME
configuration via SNMP set commands, too.
The PTP/IEEE 1588 implementation of the LANTIME is
fully compliant to the IEEE 1588 standard and
therefore provides PTP management messages as
well.
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
three additional ethernet ports and a number of
different reference time sources. Optionally several
additional frequency-, serial string- and pulse
outputs are available and by combining two (even
different) time sources and redundant power supplies,
high-availability systems are no problem. The
excellent oven controlled oscillator (OCXO-HQ) offers
fantastic holdover characteristics (e.g. when PTP
synchronization is not available).
