Q

Which of the following is a correctly formatted Inmarsat-C address book entry for sending TELEX communications to two Inmarsat-C terminals in the POR?

🔍 Key Concepts

• Structure of an Inmarsat-C Telex address (service code + ocean region code + terminal number) • Which leading digits identify the Pacific Ocean Region (POR) for Inmarsat-C terminals • The need for both terminals in the same ocean region to share the same ocean region code but have different terminal IDs

💭 Think About

• Look at the first three digits of each number: which pattern matches the Inmarsat-C numbering plan for the Pacific Ocean Region? • In the options where there are two numbers, are both clearly in the same ocean region, or does one look like it belongs to a different region or service? • Among the choices that keep the same region code for both entries, which one keeps a consistent format for all digits (no obvious change from terminal ID to something that could be a coast/land earth station code)?

✅ Before You Answer

• Confirm which 3‑digit code corresponds to the Inmarsat‑C Pacific Ocean Region (POR) numbering scheme before picking an answer. • Verify that both entries in the chosen option use the same ocean region code while having different final digits for separate terminals. • Check that the total length and pattern of each number matches a standard Inmarsat‑C Telex terminal address (no extra or missing digits, no change of region).
