Как выжать максимум возможного из IDC 2814BXL+ (Lucent)?

[Valeriy]

соединяеться на 26400/28800 очень редко на 31200,
а собрат 5614BXL/VR Plus,всегда на 31200 редко на 33600,
может настройки покрутить,что посоветуете:

вот статистика и дамп настроек для IDC 2814BXL+
прошивка,последняя 2.10

P.S.
а количество ретрейнов на IDC 2814BXL+ значительно меньше,
чем на 5614BXL/VR Plus.

Кажется, Вы перекрутили агрессивность. Попробуйте S39=64. Можно ещё попробовать уменьшить уровень мощности передатчика до -15 dBm (S64=15). Вот, пожалуй, и всё. Что касается большей скорости соединения у IDC/VR+: так и модем поновее! Однако окончательные выводы стоит делать по производительности (CPS) одного и другого модема.
