conservative busy-tone multiple access
abbr. C-BTMA
многостанционный доступ с сигналом занятости и защитой (разновидность метода МДСЗ в ПРС, при которой каждый узел посылает сигнал занятости, как только он обнаружит несущую, появившуюся при выходе на передачу какого-либо узла; при этом узлу разрешается передавать пакет только в том случае, если он уже не находится в режиме передачи и не обнаруживает сигнала занятости, поэтому все узлы, удалённые от передатчика на расстояние, не превышающее двух ретрансляционных участков, оказываются заблокированными в течение некоторого времени после начала передачи); см. destination-based busy-tone multiple access; hybrid destination-based busy-tone multiple access protocol
