[Technical Support]

Судя по статистике, Вы ограничили скорость соединения до 30667. Давайте сделаем так: Вы уберёте все настройки из строки инициализации, вернёте модем к заводским настройкам и пришлёте полную статистику (включая at%s м at#ud). Для сбора статистики можно воспользоваться программой IDC Diagnostics.

Кстати, какая версия микропрограммы стоит в модеме?

Давайте попробуем такую строку инициализации:

S91=15 S210.7=1 +MS=11,,,,,,21600

м ещё раз посмотрим статистику.

Скорость теперь по чему-то ограничивается до 33.6 :(

[ALiEN2k1]

У меня была такая же проблема - слишком много перетренировок у удалённого модема. Решается понижением скорости передачи. Вот, можете почитать: http://www.inpro.us.com/forum/viewtopic.php?p=2287#2287

[ALiEN2k1]

А скорость ограничена до 33.6 строкой +MS=11

[Technical Support]

Мы боремся не за скорость соединения, а за производительность модема (т.е CPS - среднее количество байт данных, принимаемых модемом в секунду). С этой точки зрения решение о переходе на V.34 - правильное.

Вам нужно избавиться от перетренировок, инициируемых удалённым модемом:

Retrains Issued/Granted/Auto. 0/11/0

Способ описывается в соседней теме, на которую ссылается предыдущий оратор

Вроде бы соединение улучшилось,но по крайней мере намного лучше чем было.
Вот статистика,в строке инициализации прописано следущее:S91=17 S210.7=1 +MS=11,,,,,,16800

[Technical Support]

Удалённых перетренировок всё ещё много. За 8 минут их должно быть не больше двух, а у Вас - пять. Нужно "закручивать гайки" - ограничьте скорость до 14400. Не поможет - до 12000 и т.д., пока не добьётесь нужного результата.
