🔍 Key Concepts

• Inmarsat-C addressing format for shore-to-shore services • Use of service codes (581 / 582) in the Atlantic Ocean Region-East (AOR-E) for Telex/TWX routing • How country code + subscriber number are combined in TELEX/TWX addresses

💭 Think About

• Which service code is associated with TWX traffic in the AOR-E, and where in the address string does that code appear? • How are TELEX country codes (like 26 for Canada TWX) and terminal numbers (like 776424) normally concatenated in Inmarsat-C address book entries? • Look at each choice and ask: Does it contain both the correct service code and the full TELEX country code + terminal number in the right order, with no extra symbols?

✅ Before You Answer

• Verify which code (581 vs 582) is used in AOR-E for TELEX/TWX via coast earth stations • Confirm that the final address must include service code + TELEX country code + subscriber number with no spaces or symbols unless explicitly allowed • Check that the Canada TWX country code 26 and the terminal number 776424 both appear, in the correct order, and that there are no invalid characters (like +) for an Inmarsat-C address book entry
