A vessel is tracking the AOR-E satellite. To initiate an operator assisted F77 ship-to-shore telephone contact to a shoreside party in the U.S.A., # 202-456-7890, through a European Earth Station, a valid Inmarsat operations/dialing sequence would be?
• Inmarsat LES (Land Earth Station) codes and how they are selected when using the AOR‑E satellite • The meaning of the leading digits 00, 011, or 111 when placing ship‑to‑shore calls through Inmarsat terminals • Standard international dialing format to the U.S.A. from an Inmarsat ship terminal, including country code and area code
• Which part of the sequence represents selecting the Land Earth Station (LES), and which part represents the telephone number being dialed? • For a call to the United States from an Inmarsat system, what is the correct order of international access code, country code, area code, and subscriber number? • Look carefully at which options include a final "#" after the telephone number and think about when that is normally required in Inmarsat dialing procedures.
• Verify which LES code is associated with a European Earth Station on the AOR‑E satellite in your study materials/tables. • Confirm the correct international prefix used by Inmarsat for an operator‑assisted ship‑to‑shore call to the U.S. (how many 1s or 0s, and in what position). • Check that the chosen option places the U.S. country code (1) and area code (202) in the proper place in the sequence, without adding or omitting digits.
