Q

Which of the following is a correctly formatted Inmarsat-C address book entry for sending TELEX communications to a vessel in the AOR-E?

🔍 Key Concepts

• Inmarsat-C numbering structure for ship earth stations • Difference between TELEX answerback format and Inmarsat mobile numbers • Which ocean region code and service code apply to AOR-E Inmarsat-C TELEX communications

💭 Think About

• Look at each option and identify which have the correct number of digits and structure for an Inmarsat-C TELEX address • Consider which leading digits indicate a telex destination vs. a standard Inmarsat mobile number • Think about which digits in the front of the number represent the Inmarsat ocean region and which represent the service (telex) code

✅ Before You Answer

• Verify which first digit(s) indicate Inmarsat mobile numbers vs telex country/service codes • Confirm the correct AOR-E code used for Inmarsat-C and how it appears in the address • Check for formatting clues such as extra characters (like + signs) or an incorrect number of digits that would make an address invalid
