4. INMARSAT C COMMUNICATIONS<br />
This chapter explains how to transmit and receive. Before conducting any<br />
communications, be sure to login with the NCS in your area, following the<br />
instructions in paragraph 2.3.1.<br />
To transmit e-mail, you may need to register for e-mail services with an LES<br />
which provides such services. Further it is necessary to register with an LES<br />
which provides e-mail services in order to send e-mail from a land subscriber to<br />
the <strong>FELCOM</strong> <strong>16</strong>. For further details contact an LES.<br />
4.1 Transmitting<br />
To transmit a message, create the message, attach the address of the recipient<br />
and then send it to the LES. The address of the recipient in the Inmarsat C<br />
system is his telex number, for transmission via landline, or MES Inmarsat<br />
Mobile Number (IMN), when transmitting to a ship.<br />
The message can be one you’ve just prepared or one stored on the hard disk.<br />
(Messages cannot be transmitted by direct keyboard input.)<br />
4.1.1 Code description<br />
Code can be specified at the terminal unit according to data type.<br />
IA5: International alphabet No. 5, ASCII code (7 bit).<br />
Specify this code to transmit English containing lower case alphabet.<br />
ITA2: No. 2 international communications alphabet (5 bit). Specify this code for<br />
message which contains only No. 2 international communications<br />
alphabet (see A-11). ITA2 code is transmitted faster than IA5 code.<br />
Land-based telex equipment uses ITA2. The LES converts all codes into<br />
ITA2. Code which cannot be converted is shown with the question mark<br />
().<br />
DATA: Data (8 bit). Use this code to transmit data.<br />
