SAFETY INSTRUCTIONS
Leave the equipment powered while
underway.
Distress cannot be communicated unless
the equipment is powered.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Turn off the power immediately if water
leaks into the equipment or the equip-
ment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.
Do not operate the equipment with wet
hands.
Electrical shock can result.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
Do not open the equipment.
Hazardous voltage which can
cause electrical shock, burn
or serious injury exists inside
the equipment. Only qualified
personnel should work inside
the equipment.
Hazardous microwave.
Do not approach within
60 cm of the antenna radome
when it is transmitting.
Microwave radiation can be
harmful to the human body,
particularey the eyes.

INMARSAT C SYSTEM
Introduction
The Inmarsat C system provides worldwide telex and data transmission and
reception of written information to owners of an Inmarsat C transceiver or a
terrestrial telex network via satellite.
Communication mode is store-and-forward telex, which means all information
sent are first stored at a LES and then delivered to designated party.
An EGC (Enhanced Group Call) receiver is built in the FELCOM to receive the
following types of messages, broadcasts from a LES:
• SafetyNETTM-governments and maritime authorities can use this service to
distribute maritime safety information to ships within selected areas.
• FleetNETTM-commercial subscription organizations or shipping companies
can use this service to transmit trade information (for example, company
news or market prices) simultaneously to a selected group of ships, to
provide up-to-the-minute information.
FELCOM allows you to make distress calls. They are given immediate priority
over all other calls, and are automatically routed to a land-based Rescue
Co-ordination Centre (RCC).
Besides its primary application of ship-shore, shore-ship or ship-ship
communications, the Inmarsat C service has also proved beneficial to trucking
firms who have found it indispensable for communicating with their vehicles. In
this manual, however, we will concentrate on ship applications, the main
application.

Inmarsat C system configuration
The Inmarsat C system consists of the Operation Control Center (OCC), Satellite
Control Centers (SCC), Network Coordination Stations (NCS), Land Earth
Stations (LES) and Mobile Earth Stations (MES). The OCC, located at Inmarsat’s
London headquarters, coordinates a wide range of activities in the Inmarsat
system, including commissioning of mobile earth stations.
The Inmarsat C system divides the world into four regions and each region is
covered by its own satellite.

In each region there is one NCS and several LESs. The NCS keeps track of all
Inmarsat C transceivers in its region and broadcasts information such as
navigational warnings, weather reports and news. The LES provides the link
between the MES and the terrestrial telecommunications networks via satellite.

NCS common channel The NCS has two major functions:
1) Transmitting information on a common channel.
2) Transmitting EGC messages to MESs.
NCS/LES signaling link This is the link between NCS and all LESs in its
region. All EGC messages pass through this link.
LES TDM channel This channel carries the circuit control signal for
MES and transmits messages from LES to MES.
MES message channel This channel carries messages from MES to LES.
MES signaling channel This channel transmits requests, distress alerts, data
reports, etc. In addition, it carries login and logout
from MES to NCS.
NCS/NCS signaling link This is the link between NCSs. It exchanges data
between MESs operating in different ocean regions.
MES interface The MES consists of the Data Circuit Terminating
Equipment (DCE) and the Data Terminal Equipment
(DTE). The DCE consists of the antenna unit, and
the DTE consists of the terminal unit, a keyboard
and printer.
Terrestrial network The major functions of the LESs are:
interface
1) Telex store-and-forward conversion
2) Handling EGC messages
3) Handling distress alerts
4) Data Reporting and Polling

INMARSAT C SYSTEM

Types of MES
There are three types of MES: class 1, class 2 and class 3. This FELCOM is
a class 2 MES.
Class 1: 1) Transmits messages to LES
2) Receives messages from LES
Class 2: 1) The functions of class 1 plus operation as an EGC receiver
when not transmitting or receiving.
2) EGC-only receiver
Class 3: The function of class 1 plus simultaneous operation as an
EGC-only receiver.
Peripheral Equipment
The following equipment can be additionally connected to the FELCOM.
Incoming Indicator (IC-306)
The IC-306 releases an audio alarm and flashes its lamp when a routine
message is received.
Distress Alert/Received Call Unit (IC-305)
The IC-305 enables transmission of the distress alert from a remote location; for
example, ship’s bridge. (For further details see paragraph 6.2.)
Distress Message Controller (DMC-5)
The optional DMC-5 provides for transmission and monitoring of the distress
alert. For further details, refer to the operator’s manual of the DMC-5.

1.1.5 Audio alarm
The audio alarm sounds and the terminal unit displays which alarm is sounding
as below.
• EGC distress or urgent message is received. (To silence the alarm, press the
function key [F10].)
• During the interval between the transmission of the distress alert (by own
vessel) and the receiving of the distress acknowledge signal from LES. (The
alarm automatically stops when your ship receives the distress acknowledge
signal.)
• The system status monitor detects equipment fault. (To silence the alarm,
press any key.)
1.2 Printer PP-510 (optional supply)
The printer prints transmitted and received messages. The POWER switch is on
the right side of the unit. A lamp on the switch lights when the power is on. If the
paper is set correctly, the ON LINE lamp also lights. When both these lamps are
lit, the printer is ready to print information received from the terminal unit. For
further details, refer to the operator's manual of the PP-510.
