Saturn B Data Service – Chapter 1. Introduction 1.1

General

The Saturn B Data Service includes the following functions:

• Asynchronous Data Service

• High Speed Data Service

• Datacom Switch Unit

The figure below shows a complete installation with the Saturn Bm

Marine terminal and the Saturn B Data Service functions.

Asynchronous Data Service, ASD

The Asynchronous Data system provides data transmission at

9.6 Kbps via the built-in modem feature of the Saturn B terminal. Only

Saturn B Data Service – Chapter 1. Introduction1.2

About the Saturn B Data Service Cont’d

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:

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):

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.
