Cabling the Clock Ports on the ITU Chassis
On the front panel of the chassis are two pairs of synchronization clock ports:
CKIN-1
and
CKOUT-1
,
and
CKIN-2
and
CKOUT-2
(one pair is redundant for the other).
CKIN-1
and
CKOUT-1
are
connected to NSP-1, and
CKIN-2
and
CKOUT-2
are connected to NSP-2.
Connect the
CKOUT
ports to provide the timing signal to a further piece of communications
equipment. The
CKIN-1
,
CKOUT-1
,
CKIN-2
, and
CKOUT-2
ports are 75ohm BNC connectors.
Cabling the Alarm Ports
The
ALARMS
port supports four alarm contact connections: two inputs and two outputs. These
contacts can be used to provide additional external alarms (audible and visual) when an alarm occurs
on the
BROAD
way system as well as to collect alarms arriving from external sources.
The
ALARMS
port is a female, DB15 connector.
The
ALARMS
port provides two alarm sense inputs, and two alarm generation outputs.
!
Alarm sense #1 and #2 (alarm inputs)
—These are used to collect alarms coming from an
external source, such as other equipment, high water sensor, fire alarms, and so forth.
