SHS Time Limit Warning
/
LANTIME systems with two built-in reference clocks
send out this message as soon as the time difference
between both clocks exceeded the pre-configured "Time
Limit Warning Level" setting.
•
Check the current time difference between the
two reference clocks in the main menu of the web
interface.
•
Check your SHS configuration under "Security
→
SHS Configuration".
Are the configured
thresholds possibly too strict?
•
Check the status of both reference clocks in the
main menu of the web interface. If one of the
two clocks is not synchronized, please refer to
the troubleshooting case for "CLK Not Sync".
•
Contact your Meinberg TechSupport and provide
a LANTIME diagnostic file, if you need further
assistance at solving the problem.
Oscillator not Adjusted
/
The internal oscillator is not (yet) fully disciplined. As
soon as this process is finished, the LANTIME sends
out a log message "Oscillator Adjusted".
The time
needed for an oscillator to be disciplined depends on
the quality of the incoming signal, the aging and en-
vironmental influences on the oscillator.

Contact your Meinberg TechSupport and provide
a LANTIME diagnostic file, if you need further
assistance at solving the problem.
Leap Second Announced
/
LANTIMEs with a GNSS reference clock (GPS / GLN
/ GNS) or long wave receiver (DCF77-PZF / WWVB
/ MSF / JJY) send out the "Leap Second Announced"
notification message as soon as they have received
the announcement by the reference signal. The GPS
satellites announce the upcoming leapsecond usually
about half a year in advance. Long wave transmitters
usually send the announcement 1 hour in advance.
•
This is only an info notification, therefore no fur-
ther action is required.
XMR Limit Exceed
/
LANTIME generates this message when the measured
time offset of an MRS time source has exceeded the
configured threshold value.
•
Check the current MRS time source status in the
Web Interface under "Clock
→
GNSS Clock
→
MRS Status".
•
Check the MRS configuration in the Web Inter-
face under "Clock
→
GNSS Clock
→
MRS Set-
tings". Are the configured threshold values (check
the "Limit" column) configured possibly too strict?
•
Contact your Meinberg TechSupport and provide
a LANTIME diagnostic file, if you need further
assistance at solving the problem.
