Question 1 of 29218

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

🔍 Key Concepts

• Inmarsat ocean regions (AOR-E, AOR-W, IOR, POR) and which one the question is asking about • The difference between Inmarsat telephone (voice) country codes and Inmarsat-C TELEX service codes • Typical number structure/length of an Inmarsat-C TELEX address book entry

💭 Think About

• Which leading digits in the options look like a telephone country code used for voice calls rather than a TELEX address? • What part of the number indicates the ocean region, and which digit(s) correspond to the Indian Ocean Region (IOR) in your study materials? • Are there any options that clearly do not match the standard pattern for an Inmarsat-C TELEX entry (in terms of prefix and length)?

✅ Before You Answer

• Identify and rule out any option that starts with a known Inmarsat voice (telephone) country code rather than a TELEX code. • Confirm from your notes which digit identifies the IOR in Inmarsat-C addressing and check that against the middle part of the number. • Verify that the remaining candidate has the correct service prefix for TELEX and the correct total number of digits for an Inmarsat-C address book entry.
