5. INMARSAT COMMUNICATIONS
This chapter explains how to send and receive. Before conducting any communica-
tions, be sure to login with the NCS in your area, following the instructions in
section 3.3.1.
To send e-mail, register for e-mail services with appropriate LES which provides such
services. Further, it is necessary to register with appropriate LES to receive e-mail
from land mail system. For further details, contact appropriate LES.
5.1 How to Send a Message
To send a message, create the message, attach the address of the recipient and then
send it to the LES. The address of the recipient in the Inmarsat C system is his telex
number, for transmission via landline, or MES Inmarsat Mobile Number (IMN), when
sending to a ship.
The message can be one you have just prepared or one stored on the hard disk. (Mes-
sages cannot be sent by direct keyboard input.)
5.1.1 Code description
Code can be specified at the terminal unit as follows:
IA5 : International alphabet No. 5, ASCII code (7 bit). Specify this code to send English
containing lower case alphabet.
ITA2 : No. 2 international communications alphabet (5 bit). Specify this code for mes-
sage which contains only No. 2 international communications alphabet (see the Ap-
pendix 4). ITA2 code is sent faster than IA5 code. Land-based telex equipment uses
ITA2. The LES converts all codes into ITA2. Code which cannot be converted is
shown with the question mark (?).
DATA : Data (8 bit). Use this code to send data.
