3. Designing a system
The intentions of this chapter is to be a guide
to how to design an on board communication
system, how to choose the right system
components, and how to build the exchange
system.
It is to be used by the people who makes
quotations to ship yards and ship owners, as
well as the technicians who is actually
assembling and installing the components.
3.1 Analyzing
All ships ha e dif ferent needs. This is what
makes design and installation of on board
communication challenging. The SeaCom
3000 maritime communication system is a
ery f lexible configurable system which allows
You to meet by f ar the most requirements.
In order to architecture a proper system, You
must first collect information about:
 Number of locations that need
communication
 The en ironment to be expected at
each location
 Type of communication to be carried
out at each location
 Number of Satellite lines to be
connected.
3.1.1 Counting locations
The number of locations needing telephones
must be determined. This is done in
cooperation with ship architect and owner.
The number determines the size of the
exchange system to be chosen.
3.1.2 En ironment
On each location, the expected noise le el
must be known, and the location must be
classif ied as protected or exposed, where
protected areas are locations like cabins,
off ices and bridge, whereas exposed will be
areas like engine room, mooring stations or
workshops.
3.1.3 Type of communication
On each location a choice of which kind of
communication is most con enient must be
made. The SeaCom maritime communication
system of fers the below communication styles:
 Handset con ersation
 Hands-free con ersations
 PTT mode (push to talk)
 Headset con ersation
Each station can of fer the seamen one or
more of these styles. It is important to select a
style that fits to the needs and which can be
operational in the gi en en ironment f or the
intended use.
3.1.4 Satellite lines
Count how many 2 wire trunk lines will be
needed for connecting satellite communication
equipment.
3.2 Selecting telephones/stations
Based on the analysis, the equipment to be
placed at each location must be selected.
The table below shows typical noise le els to
be encountered on ships.

3.3 Designing the exchange system
The SeaCom 3000 is a scaleable system. It
comes with 24 extension lines and 2 trunk
lines, and can be build up to 144 extensions.
The components used to build the system are:
 AEXT16 extension line card
 FIO4 trunk line card
 CTU2 Cable termination card
 CTU24 Cable termination card
 PDU Power distribution card
3.3.1 AEXT16
This board adds 8, 16 or 24 extension lines to
the system. Each telephone or
communication station on board requires one
extension line.
3.3.2 FIO4
This board adds 2 or 4 trunk lines to the
system. Trunk lines are used to connect to
satellite terminals, GSM terminals or shore
lines.
3.3.3 CTU2 and CTU24
These boards are used to terminate the ship
cables inside the SeaCom 3000. The CTU2
terminates 16 extension lines and the CTU24
terminates 24 extension lines.
When using the FIO4 board, the 2 or 4 trunk

SeaCom3000 User Manual Page 20 of 94
SeaCom TMN20170417CJ01_0109
lines will occupy the space of 8 extension lines
on the CTU2 or CTU24.
3.3.4 PDU
24V DC has to be distributed to the SC411,
SC211 and SC421 stations in use. The PDU
allows f or this including proper fusing of the
lines. 18 stations can be powered by the
PDU.
3.3.5 Exchange design example
On a ship we ha e f ound out that the below
telephones and stations are required:
4 x SC211
2 x SC411
12 x SC421
4 x SC220
35 x TX325
A total of 57 positions
The SeaCom 3000 comes with 24 extensions,
so we need to add another 33 extension
lines. We choose the AEXT16-24 to add 24
and the AEXT16-16 to add the remaining 9.
Along with the two extra boards, we need a
CTU24 for the additional 24 lines and a CTU2
for the 9 lines.
We ha e 4 + 2 + 12 = 18 positions that require
24V DC, and that can be co ered by adding
one PDU.
3.4 Power considerations
The SeaCom 3000 and the stations are all
powered by 24V DC. This paragraph
describes how to calculate the power required.
3.4.1 Power consumption - exchange
The power needed for the exchange system
can be roughly calculated from the below
formula:
Pexh = 15W + 0.25W * Next
where
Next is the number of extensions installed.
Pexh is the stand by power used by the
exchange.
3.4.2 Power consumption - stations
Except f or the analogue telephones and the
SC220, all the communication stations also
require 24V DC power. The power needed
depends on the actual operation of
communication, where especially the PA calls,
which can engage all stations simultaneously,
must be taken into account, in order to ensure
that the peak power needed can really be
deli ered by the power supply chosen.
A guideline is:
Pstby = 2.0W * Nst
Ppeak = 2.0W * Nst + 22W * Nstpa
Pstby is the idle power used
Ppeak is the peak power used
Nst is the number of stations
Nstpa is the number of stations engaged
in PA calls
3.5 Wiring schematic
Based on the design of the system, it is the
responsibility of the installer to create proper
electrical schematic drawings and
documentation to be used while installing.
This manual is a generic manual, and cannot
be an instruction and the documentation
deli ered to an end user on its own.

4. Installation
This chapter gi es some guidance in how to
install the SeaCom communication system.
Considerations to be taken, and good practice
to follow. For detailed mechanical drawings
and details on electrical terminals, refer to
later chapters.
4.1 The exchange
The SeaCom 3000 exchange must be located
in a dry entilated space with a maximum
ambient temperature of 55 dgs, the cooler the
longer lif etime shall be expected.
The exchange must be mounted on a
bulkhead in a ertical style to ensure that the
intended air flow can be realized.
Do not mount the exchange horizontal.
The bolts to be used are 6 to 8mm torx or x-
dri e, and should be used like shown on the
following pictures:
4.2 Mounting the stations
The stations are either f lush mount or
bulkhead mount.
4.2.1 Flush mount
SC411 is meant for screw less console flush
mount.
It is important to make a precise cutout, in
order to be able to make the required
electrical isolation between the station and the
steel of the console.
