To initiate an automatic ship-to-shore telephone contact through Southbury Earth Station, which dialing sequence is correct if the vessel is tracking the AOR-W satellite?

To initiate an automatic ship-to-shore telephone contact through the Southbury Earth Station while tracking the AOR-W satellite, the correct choice follows the established protocols for accessing the Land Earth Station (LES) and includes the appropriate dialing format.

The correct answer includes the proper identification of the Southbury Earth Station with "LES 001" followed by the correct international dialing sequence. The format "0011234567890#" indicates that the number being called is prefixed correctly for international dialing, aligning with the standards for making a call from a satellite communication system. The use of "001" serves as the appropriate country code or international access code, which is necessary for correct routing of the call over the network.

Understanding the significance of the other options helps to emphasize why this selection is correct. Any variations in the LES number or the dialing format could result in failure to connect. It is critical to use the accurate LES number "001" as designated for Southbury, combined with the proper dialing method to ensure the call is processed correctly through the satellite system. Such attention to detail is essential in GMDSS operations to maintain effective communication in maritime contexts.
