If your vessel is in the IOR, which is a correctly formatted Inmarsat-C address book entry for sending communications to a shoreside TELEX terminal number in the Philippines?

The correctly formatted Inmarsat-C address book entry for sending communications to a shoreside TELEX terminal number in the Philippines is based on the specific structure that is required for final addresses in the Inmarsat system.

Inmarsat-C utilizes a specific numbering scheme, where the first few digits represent the country code or geographic area the terminal is associated with, and then is followed by the unique terminal number. The selection you mentioned consists solely of a numeric sequence which is indicative of a TELEX terminal.

In this context, the entry must include the full number without a leading zero or any other prefixes that are used for other forms of communication, such as international dialing codes. The inclusion of the '+' sign or other leading digits would not align with the standard formatted entry expected for Inmarsat-C communications with shoreside TELEX terminals.

This particular format adheres to the conventions and practices set forth for maritime communication, ensuring that messages are correctly routed to the designated TELEX number without additional prefixes or variations that could result in misdelivery. Therefore, a straightforward numeric representation without unnecessary characters is essential for this kind of communication entry.
