2.4 EGC Settings<br />
2.4.1 What is the EGC (Enhanced Group Call) service?<br />
2. SYSTEM INITIALIZATION<br />
The EGC service enables EGC information providers to send SafetyNET TM ,<br />
FleetNET TM and System messages via an LES to a specific groups of ships, or<br />
to all ships within a defined geographical area.<br />
Each type of EGC service is sent as follows:<br />
1) The information provider prepares the message, and then accesses the<br />
appropriate Country of the international telex network to send the message<br />
to an LES.<br />
2) The LES processes and forwards it to the NCS for the ocean region<br />
designated by the provider.<br />
3) Then, the NCS broadcasts the message throughout the ocean region. (The<br />
operator may choose the EGC messages to receive by position (one<br />
position) and geographical position (nine areas). For further details see<br />
paragraph 2.4.2.)<br />
