General description
Overview
The SAILOR 4300 L-Band 
System consists of an ADU 
(Above Deck Unit) and a 
BDU (Below Deck Unit). The 
two units are connected with 
a single coax cable with TNC 
female connectors. The 
system is DC powered. The 
SAILOR 4300 L-Band System 
is used for voice calls and 
data sessions. 
Data rates and coverage
Iridium OpenPort Services offer up to 134/134 kbps, while Iridium Certus 
350 Services offer up to 176/352 kbps. Iridium has 100% global coverage. 
Some countries may have national restrictions. 
SAILOR 4338A Below Deck Unit (BDU)
The BDU is the central unit in the system. It contains all user interfaces and 
handles all communication between the ADU and the local communication 
units (phones, computers etc.). 
SAILOR 4352A Above Deck Unit (ADU)
The ADU consists of an antenna with an RF-unit, unit for antenna control 
and GPS antenna. The ADU is dedicated to the Iridium system. 

Chapter 1:  Introduction
2 General description
Data sessions and voice calls
The SAILOR 4300 L-Band System provides up to 3 simultaneous IP voice 
calls or 3 data sessions or a combination thereof with a maximum of 3 
connections in total.
The BDU has three user ports for user data traffic. A data session can be 
activated automatically at start-up or manually. The BDU has a DHCP server 
with a configurable start/end range of IP addresses for user devices. Also it 
includes port forwarding with up to 8 configurable forwarding rules for UDP 
and TCP protocols.
The BDU communicates directly with SIP phones on any of the three LAN 
user ports (LAN 2, 3 or 4).
To set up a VoIP phone see To connect a PC and SIP phone on page 7.

Operation
To power up the system, do as follows:
1. Power up the system, i.e. switch on the terminal.
2.
3. Wait until the LEDs at the rear of the terminal show that the system is 
ready to be accessed.
• Power LED: Green
• Terminal: Steady green.
• Antenna: Steady green.
4. The system is ready for use.
To connect a PC and SIP phone
Connect your equipment to the Ethernet connector(s) marked LAN. You 
need a straight LAN cable.
SIP telephony service
The SAILOR 4300 L-Band system has a built-in SIP server which provides up 
to three voice lines to users connected to the BDU. To use this service you 
need one or more VoIP-phone or soft-phone (mobile apps, PC software). 
The effective number of available voice lines depends on the subscription. 
Each voice line has a dedicated mobile number and is available through one 
of the internal SIP user names line1, line 2 and line3. The mapping from

Wait until there is light in the Power LED.

Chapter 2:  Operation
8 Getting started
subscribed mobile number to the SIP user name is fixed. For an example see 
the following table.
See your subscription information for the exact details on which mobile 
number is assigned to which user name.
To connect one or more VoIP-phone or soft-phone (mobile apps, PC 
software), do as follows:
1. In order to use the telephony service connect a SIP or VoIP enabled 
telephone to a user port of the BDU and register it with the built-in SIP 
server.
2. If a router or wireless access point is used to connect the telephone, 
make sure that the required protocols for VoIP telephony. You can find a 
list of these protocols at the end of this chapter.
3. For the registration on the BDU a number of network-specific 
parameters are necessary, which are stored in a "SIP profile" in the 
telephone. At least configure the following items:
Mapping from subscribed mobile numbers
User name Mobile number Line type Voice quality 
line1 8816xxxxxxx1 PostPaid HQ
line2 8816xxxxxxx2 PostPaid HQ
line3 8816xxxxxxx3 PostPaid HQ

Operation
You can use all available mobile numbers and user names from within one 
telephone or application. That means that you can handle all your 
subscribed numbers from one device. Note that not all devices might 
support subscribing to more than one line. See the device's user manual for 
details.
Suitable telephones for this service are dedicated stand-alone VoIP-, IP- or 
SIP-telephones, or soft-phone applications running on a PC or mobile 
phone. A VoIP-app on a mobile phone can only be used if the phone is 
connected to the device via a separate wireless router. Any modern SIP-
telephone or software are suited for use with the SAILOR 4300 unit, though 
this cannot be guaranteed for a specific type of device or software.
At least the following protocols and codecs must be supported:
Note For details of how to configure your device consult the 
telephone's user manual.
Important You cannot register more than one telephone on the same 
mobile number respective user name on the SIP-server. If 
more telephones register with the same SIP-profile, only the 
last telephone registered will be subscribed to the mobile 
number and be able to use this number for receiving and 
making calls.
