Разницу по словарю я не понял, но в случае с астериском появляется лишний байт
(содержащий логичекийномер span
[trunkgroups]
trunkgroup => 2,47
spanmap => 2,2[,логический номер span]
)!
Ну и в EWSD есть пакет
-- High layer compatibility (7D 02 91 81)
Как заставить атериск передавать бит Implicity ?????
Доброго всем здоровья!
