What must be included when sending TELEX to a shoreside terminal in Japan?

When sending a TELEX to a shoreside terminal in Japan, it is essential to include the appropriate international dial code for Japan, which is represented by the numeral 81. The correct format requires the inclusion of this dialing code followed directly by the local number, ensuring that the transmission is accurately directed to the intended destination.

Including the dialing code in the specified format (81) before the actual local number is standard practice for international communication, as it informs the network that the message is destined for Japan. Clarity in format reduces the chances of transmission errors or misdirection and is critical in professional communication environments.

In contrast, while the other options contain elements of the necessary information, they diverge from the correct format either by omitting components or changing the structure. The correct selection ensures that the TELEX is not only correctly formatted but also adheres to international standards, facilitating effective communication.
