SYNCHRONIZATION SIGNALS DISTRIBUTION
The distribution of the synchronization signals (1PPS, 10MHz) depends on the mute mode (defaulted to
‘Auto
matic
’ mode, see
In ‘Disabled’ mode
, the synchronization signals (1PPS, 10MHz) are
ALWAYS
delivered
(once the
initialization of the EC20S is complete)
–
but need to meet the SFN condition after start up (see 10.2).
Refer to the diagrams in the following paragraphs.
In ‘
Automatic
’ mode
, the synchronization signals (1PPS, 10MHz) are
delivered
(once the initialization of
the EC20S is complete)
only if
the EC20S meets the SFN conditions
(i.e. when SFN Status is ‘
On
’,
see
In ‘
On Time
’ mode
, the synchronization signals (1PPS, 10MHz) are
delivered
(once the initialization of
the EC20S is complete)
upon timeout conditions
defined by 3 parameters 74, 75 and 76 at 13.7.5.
The
presence of the distributed synchronization signals (1PPS, 10MHz) is monitored
:
-
by
the ‘
DST
’ LED
(see 11.1),
-
by the ALARMS signalling (see 11.2.1),
-
Using the web interface: see 13.3.2.7 and 13.3.3,
-
Using the SNMP interface: see 14.1.1, SNMP parameters 20 and 21.
