Question

If your vessel is in the IOR, which of the following is a correctly formatted Inmarsat-C address book entry for sending communications to a shoreside TELEX terminal number 77829 in the Philippines  (TELEX country code 758)?

Accepted Answer

Option C: 75877829. Inmarsat-C Telex addressing is independent of the ocean region (IOR, POR, AOR). The address book entry requires only the country code (758) and the subscriber number (77829). Concatenating these yields 75877829. Additional symbols like plus signs are not part of the standard addressing protocol for Telex terminals.
