What is the correct Inmarsat-C address book entry format for sending communications to a shoreside TELEX terminal number 776424 in Canada?

The correct format for an Inmarsat-C address book entry to send communications to a shoreside TELEX terminal number is based on the country code and the specific format standardized for telecommunications. In this case, the TELEX number 776424 in Canada corresponds to the country code for Canada, which is 267.

As part of the Inmarsat-C messaging system, you combine the country code with the TELEX terminal number to create the full address. In this case, the combination results in 26776424, which indicates that it is directed to the TELEX service in Canada. The absence of additional prefixes or numbers signifies that the number is correctly formatted for the Inmarsat-C communication system without requiring further modifications.

In contrast, other entries may have additional codes or misformatted structures that do not comply with the established standards for TELEX machine connections within the Inmarsat-C framework. This makes 26776424 the precise and appropriate address book entry for the given TELEX terminal number in Canada.
