The services currently supported by the SAILOR FleetBroadband comprise:

• A Packet-Switched (PS) connection to the Internet

• A Circuit-Switched (CS) dialed connection for voice, fax or data

• Short Messaging Service (SMS)

•Multi-voice

• Voice Distress

Packet data service

The BGAN network supports different classes of data connection to the
Internet.

•Using a Standard IP connection several users can share the data

connection simultaneously. This type of connection is ideal for e-mail,
file transfer, and Internet and intranet access. The user pays for the
amount of data sent and received.

•Using a Streaming IP connection you get an exclusive high-priority

connection ensuring seamless transfer of data. This type of connection
is ideal for time critical applications like live video over IP. The 8 and
16 kbps connections are well suited for Voice over IP. The user pays for
the duration of the connection (per minute charge).

Note

The BGAN system supports maximum 11 concurrent Packet
Switched connections at a time per SAILOR FleetBroadband
system.

Chapter 1: Introduction

14 The Inmarsat BGAN system

Circuit-Switched (dialed) service

The following types of circuit-switched connection are available:

• Standard Voice. A low-tariff connection for voice only. The voice
signal is compressed to 4.0 kbps, which reduces the bandwidth use and
consequently the tariff.

• 3.1 kHz Audio. A high quality connection which can be used for
Premium Voice or G3 fax. The signal is uncompressed 3.1 kHz audio,
which allows for optimum voice quality. Note that the 3.1 kHz Audio
service may have a much higher tariff than Standard Voice.

• ISDN. A high quality connection which can be used for voice (3.1 kHz
Audio), G4 fax or 64 kbps UDI/RDI data.

SMS service

The BGAN system provides a Short Messaging Service (SMS) for sending
and receiving SMS messages to and from the terminal.

Multi-voice service (optional)

Normally, the BGAN system only supports one call at a time per
SAILOR FleetBroadband System. When you subscribe to the optional Multi­voice service and enable it in your system, you can have up to 9 concurrent
calls.

To use the Multi-voice service you must enable Multi-voice in the web
interface of the SAILOR FleetBroadband terminal. For information on how
to set up Multi-voice, see Multi-voice on page 190.

Voice Distress service (optional)

The Voice Distress service uses FleetBroadband to provide priority call
access as soon as the red distress button on the alarm panel is pressed. The
caller will then be connected to an operator at one of three Maritime
Rescue Coordination Centres (MRCCs) strategically located around the
globe.

To use the Voice Distress service you must first have it included in your
airtime subscription, acquire a SAILOR 3771 Alarm Panel and use the web
