INMARSAT-C COMMUNICATIONS

This chapter explains how to transmit and receive in the Inmarsat-C system.

Before conducting any communications, be sure to login with the

NCS in your area.

To transmit E-mail, register with the LES provider. E-mail charges are calculated separately.

Transmitting

To transmit a message, you first create the message, attach the ad- dress of the recipient and send it to the LES. The address of the re- cipient in the Inmarsat-C system is his telex number for land-line or MES Inmarsat Mobile Number (IMN) for ship.

The message can be one you’ve just prepared or one stored on a floppy disk. (Messages cannot be transmitted by means of direct keyboard input.)

Code description

Code can be specified at the IB-581 or PC.

IA5:	International alphabet No. 5, ASCII code (7 bit).
	Specify this code to transmit English containing lower case
	alphabet.
ITA2:	No. 2 international communications alphabet (5 bit).
	Specify this code for message which contains only No. 2 in-
	ternational communications alphabet (see A-11). ITA2 code
	is transmitted 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 a question mark (?).

DATA: Data (8 bit). Use this code to transmit data.
