What keyboard entry would you make on an Inmarsat-B terminal for an automatic TELEX connection to 882419 in Nebraska, USA (TELEX country code 230)?

Correct Answer: Option C — 00230882419+

Automatic TELEX dialing requires the access code, the country code (230 for USA), and the subscriber number, terminated by the + character. This sequence ensures the Inmarsat-B terminal correctly interfaces with the Coast Earth Station to route the TELEX to the specific domestic subscriber in the United States.
