Status Indicator
The LED Status Indicator is primarily intended to support installation personnel for
immediate feedback. The following sequences define the Fixed Network solution's
operational characteristics:
Sequence details: The dot time: 100 mSec
The dash time is 300 mSec
Off Time between B and N: 700 mSec
Off time between dot and dash: 100 mSec
Off The collector is not running. Off
Powered

Time Acquisition The collector is attempting to
synchronize its system time with
an external time reference through
NTP and/or GPS.

NTP. Instead, repeaters acquire
time from either the collector or
from GPS. If time is received from
the collector, the repeater status
indicator will not display the
Morse T.
