Description
Meinberg LANTIME time server are used around the
world to provide accurate time to networks of any
size. The LANTIME M300/MRS is a very reliable and
accurate time source for all systems either NTP- or
SNTP-compatible and it uses a built-in ultra-stable
oscillator as its primary reference time source.
The Meinberg MRS technology (Multi Reference
Sources) enables you to utilize one or more time and
frequency references in prioritized order defined by
your individual requirements. The Intelligent
Reference Switching Agorithm (IRSA) developed by
Meinberg engineers ensures that switching from a
highly accurate reference source (e.g. GPS) to a less
accurate one (e.g. IRIG or NTP) is delayed as long as
the internal ultra stable oscillator is capable of
maintaining an accuracy level that is better than the
one of the next available reference source in the
priority list.
In lab environments the MRS technology offers a
flexible solution to changing availability of
different synchronization sources and for highly
critical operative systems the possibility to use
multiple independent sync references allows you to
fulfill redundancy requirements of your network
synchronization solution.
Another field of applications for MRS technology
is the monitoring and measurement of synchronization
sources, e.g. determining and logging the accuracy of
an IRIG generator or a PPS source.
The MRS version of the LANTIME M300 comes with a
high quality OXCO and is designed to act as a
reliable time source in applications where no antenna
can be installed. The internal OCXO-HQ can be fully
disciplined by utilizing one or more remote NTP time
servers or the other input sources. In installations
where no source of time is available, the LANTIME
M300 MRS can be run in a fully independent mode which
requires setting the time manually during initial
configuration. Such a free running MRS (i.e. without
any available external reference like GPS or NTP)
develops a maximum time error of less than one second
per year.
All outputs of the M300, including PPS, 10MHz and
the Sysplex Timer output are fully functional and
stable with all possible references (NTP, GPS, 1PPS,
10MHz, IRIG or free running).
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 LC display shows the state of the internal
GPS receiver and the NTP subsystem. Three LEDs
(green/red) indicate the status of the three main
components: Reference Time (GPS), 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 managed 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 Meinberg LANTIME
time servers satisfy the 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 our
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 GPS and NTP
status information as well as the complete system
configuration) and can be used to alter the LANTIME
configuration via SNMP set commands, too.
LANTIME time servers are designed to be deployed
in IPv4, IPv6 and dual stack networks , the NTP time
synchronization as well as the configuration
interfaces (Web-based, SSH and SNMP) comes with full
IPv6 support. You can assign several static IPv6
addresses and the system supports automatic
configuration by IPv6 autoconf.
Please note that the GPS antenna is not included
in the standard scope of delivery and has to be
ordered separately, if you are planning to use GPS as
a synchronization source.
