Здравствуйте.
Можно ли выжать еще что-то из модема на моей линии,
скорректировав строку инициализации?
И вообще, что можно сказать о линии, исходя из приведенного ниже отчета?

Попробуйте прописать такую строку инициализации:
S91=12 S210.7=1 S51=0 S202.3=1 +MS=11
и покажите, что получается в статистике. _________________ Inpro

Попробовал данную строку. Стало невозможным соединиться с провайдером. Методом исключения выяснил, что виноват параметр S51=0. Поэтому привожу статистику без него.

В общем стабильность закачки стала лучше. Если раньше было заметно моргание индикатора RD, то сейчас он горит почти ровным светом.
Спасибо за помощь.
P.S. А утром удалось соединиться даже на 28800:

S51=0 позволяет модему использовать бОльшие,, чем 2400 симв/с, символьные скорости, даже при плохих значениях SNR. Но похоже, что на Вашей линии это практически невозможно. Так что работайте при настройке S51 по умолчанию. _________________ Inpro

Здравствуйте. В продолжении темы подскажите как добиться лучшего результата? Качество линии нестабильно, но иногда на большем значении скорость меньше.

Попробуйте такую строку инициализации:
S91=15 S210.7=1 +MS=11,,,,,,16800
Покажите, что получается в статистике. _________________ Inpro

Хотелось бы преодолеть скорость 33600. В основном соединялся раньше на 28800...33600.
Вот с новыми настройками 33600 преодолеть пока не удалось.
Жаль что флекс не завязался.

Гм... Строка инициализации конкретно говорит, чтобы модем соединялся на V.34 (+MS=11). Борьба шла за уменьшение количества перетренировок по инициативе удалённого модема, и судя по статистике, всё получилось! _________________ Inpro

Судя по статистике, бороться за V.90 (и тем более за K56Flex) смысла нет. В случаях, аналогичных Вашему, на этих протоколах получаем, в лучшем случае, 32000 бит/с (что медленнее, чем 33600). _________________ Inpro

Здравствуйте.
На днях у провайдера заменили сервер и впервые появилась возможность связи на 56 (V90). Подскажите пожалуйста и мне, можно ли улучшить скорость соединения. Заранее благодарен, Олег.

Олег, скорее всего у Вас в свойствах модема прописана некая строка инициализации, которую IDC Diagnostics "не видит". А не видит потому, что Вы прописали эту строку после того, как IDC Diagnostics выполнила процедуру определения модема. Пожалуйста, сообщите нам эту строку. И заодно повторите процедуру определения модема (кнопка "Detect modem"), чтобы IDC Diagnostics в дальнейшем показывала строку инициализации в журнале. _________________ Inpro

На самом деле все было так:
Я просто для интереса тупо скопировал строку инициализации из одного из Ваших ответов в этой же теме, вот эту - S91=18 S210.7=1 S55.4=1 S202.3=1 S17=56. Перед диагностикой я удалил ее, но видимо не учел, что она продолжает действовать до перезагрузки компьютера. Но зато лишний раз убедился, что с проблемой обратился как раз по адресу.
На этот раз привожу "чистую" диагностическую информацию, без строки инициализации:
