Meinberg LANTIME/SHS/BGT Manual

LANTIME/SHS/BGT: NTP Time Server with Integrated Highly Secure
Hybrid Receiver Technology (GPS/DCF77) in 3U housing
Meinberg LANTIME time servers are used around the world to provide accurate time to networks of any size.
The SHS model synchronizes all systems either NTP- or SNTP-compatible and uses a built-in Meinberg
integrated GPS radio clock as its reference time source and additionally includes an independent secondary
clock for enhanced plausibility checks, in order to ensure the correctness of the reference time and date.
If either the difference between the time telegrams of both radio clocks or the difference between the PPS
signals exceeds a limit of a few milliseconds (configurable), or if one of the clocks stops generating a time
telegram, then the hybrid radio clock stops generating any output signals, preventing the NTP time server
from spreading bogus time information on the network.
Both the primary and the secondary clock include their own high quality crystal oscillators which let the clocks
provide accurate time even if they are running free for a few days. Both clocks generate their own time
telegrams and high accuracy pulse-per-second (PPS) signals which are continuously compared against each
other. During normal operation the difference between the timing information of both clocks is very small, so
the verified timing signals are passed to the integrated NTP time server which makes that reference time
available on network.
