modem communication software needs to be installed in the associ-
ated PC to allow data transfer.
See chapter 2. Asynchronous Data.
High Speed Data Service, HSD
The Saturn B High Speed Data system provides a 56/64 Kbps full
duplex link with a terrestrial ISDN network (see figure 1.1).
The data transfer is six times faster compared to other types of data
transfer systems using lower speed (e.g. data modems with data
transfer rates such as 9600 bit/sec).
The paid connecting up time for Inmarsat-B HSD is very short (less
than 4 secs), whereas it for an analogue data modem can be 40 sec.
Use of Saturn HSD is described in various application notes available
from Nera.
The system gives possibilities to utilize the ISDN data transfer for
applications such as:
•High quality sound transmissions for broadcasting using wide
bandwidth audio codecs such as G-722 or Musicam.
•Video conferences
•Store and forward transmissions of compressed video.
•High quality Class 4 facsimile.
•Multiplexed data, facsimile and voice.
•Connection between data networks using data bridges or routers.
See chapter 3. High Speed Data.
Datacom Switch Unit
The Datacom Switch Unit (DSU) allows both an HSD and ASD sup-
ported equipment to be connected at the same time to the DTE port
of the Saturn B.
See chapter 4. Datacom Switch Unit.
Implementation
The ASD and HSD options are available in all Saturn B terminals, and
can be opened for operation by a code supplied by any of Nera ASA
agents. See "Renter/Owner Level: Optional Functions".
About the Saturn B Data Service

Saturn B Data Service – Chapter 1. Introduction 1.3
Protection
Two password protected user levels are provided in addition to USER
and OPERATOR level:
•RENTER, and
•OWNER
A common default password (1 2 3 4 5 6) facilitates the activation of
Enhanced Functions for new users (see "Password").
Warning! An individual OWNER password must be entered to protect
the equipment against unauthorized use. The password must be
stored in a safe place.
Up to three different operation rights can be assigned with selecta-
ble access level to each Enhanced Function:
•SETUP OPERATION –allows such as selection of ports.
Default access level: OWNER.
•UPDATE OPERATION–such as entering/deletion of data.
Default access level: OWNER.
•VIEW OPERATION –such as display readout and printout.
Default access level: OPERATOR
When activating a function, the access level required to operate each
right can be seen in the display when pressing MORE/HELP.
See example below.
Setup operations can be accessed from RENTER or OWNER level
only.

Saturn B Data Service – Chapter 1. Introduction1.4
General
The Saturn B terminals provide the following access levels in addition
to USER (1) level and OPERATOR (2) level:
•RENTER (3), and
•OWNER (4)
The RENTER and OWNER levels are protected by passwords.
The default password for both levels is 1 2 3 4 5 6.
Password protection can be used to restrict operative functions to
different parameter levels, e.g.:
•level 4 (OWNER) allowed to change setup.
•level 3 (RENTER) allowed to read data.
•level 2 (OPERATOR) given no access to reading or setup.
•level 1 (USER) has standard minimum operational functions.
These restrictions can be applied according to function, e.g.:
the RENTER level can be allowed to configure the ASD function, but
restricted to reading only in the access code function.
An individual password may be assigned to each level using the "SET
PASSWORD" function no.13, see "Password".
To Set Access Level:
1 Select SET USER LEVEL function (12):
2Display the current level:
3Key in operator level ref. number,
e.g. 3 (RENTER):
3=RENTER, 4=OWNER
4Key in the current password for this
level (the default password
is 1 2 3 4 5 6):
5 The terminal is now set to RENTER LEVEL:
This level is active until a new level is set or the
terminal is switched off. Therefore, set the level
back to USER when finished with your operations.

The RENTER and OWNER levels are protected by passwords.
The default password for both user levels is 1 2 3 4 5 6.
The password may be changed individually to any password contain-
ing at least 4 digits. The owner may change password for both OWN-
ER level and RENTER level, whilst the renter only may change
password for the renter level.

Introduction
Features
The Asynchronous Data (ASD) system allows data transmission
between the Saturn B terminal and:
• a remote computer connected to a standard modem that can be
routed via the telephone network to an Inmarsat Land Earth Sta-
tion (LES) offering the Inmarsat-B ASD services.
•
a remote Satellite terminal supporting the Inmarsat-B ASD data
service.

Installation
Connect the enclosed RS-232 interface cable between the serial port
on the PC and the 25-pin DTE port on the Main Control Unit.
The example in figure 2.1 shows connection to a standard Main
Control Unit. The location of the DTE connector varies with type of
Saturn B terminal, see the individual Saturn B Operator’s Manual.
Activation
The Asynchronous Data Function is activated using the "Enhanced
Setup" function no. 89.
If not yet activated it appears as "PASSIVE" when opening the "En-
hanced Setup" function no. 89.
See "Activating the ASD Function".
Testing the installation
Entering a command on the PC keyboard as f.ex. ATç should
cause "OK" to be displayed on the screen.
If no response, check that the baud rate set using the Display Hand-
set function no. 86 is the same both for the PC and the MCU.

Operation
The Saturn B Asynchronous Data link is operated in three ways:
•hotline call, i.e. interactive computer controlled interface, or
•
manual call, by using the Display Handset or Telephone.
• AT calls, by using the PC keyboard.
Hotline Call
This mode is intended for equipment such as computers, network con-
nections and other equipment that can utilize the CCITT V24 protocol for
connecting up and clearing the communication. Circuits no. 108 (DTR)
and 125 (RI) are used for automatic connection and clearing.
Dialing
When circuit 108 goes high, the number stored in short number 98 is
sent automatically. Calls are cleared when circuit 108 goes low.
Manual Call
Manual mode is intended for equipment which lack signalling features
such as audio codecs.
Dialing from Display Handset
When dialing the remote end subscriber number from the Display
Handset, Saturn B features such as using default LES, selected LES,
short number dialing and direct dialing may be applied.
For access to manual ASD calls,
key *2 5 *9 6 #:
