У Inmarsat есть официальный сайт
http://www.inmarsat.com/ .
Там очень много полезной информации , в том числе и troubleshoting, что означает решение возникших проблем.Там есть back коды для телексов. Даю ссылку
http://www.inmarsat.com/Support/Inmarsa ... only=FalseДело в том, что telex это такая система, которая выдает сообщение, особенно об ошибке, ввиде кода, и его надо расшифоровать, для этого есть таблица. И члены экипажа, отвечающие за связь, поскольку уже в чистом виде таких нет, узких спецов, должны знать, как работает, а иначе, как знать что произошло. Даю расшифровку кода ниже. Если что, спрашивай:
