The one-way latency timestamp is synchronized with an external 1PPS
clock. One-Way latency is only possible when both the local and remote
1PPS signal clocks are valid. The following alarms are available with
One-Way latency measurement mode.
LOPPS-L
and
LOPPS-R
(Loss Of Pulse Per Second - Local/Remote) is
declared when either no pulse is received or when no pulse is received
within 1 second ± 6.6
μ
s after the previous pulse. LOPPS-R is only
monitored once the DTS connection is established.
