Может после перепрошивки стало лучше?

[Kiskos]

Добрый день!
Около года назад помогли мне добиться более-менее стабильной связи со строкой инициализации S91=15 S210.1 +MS=11.
Вчера перепрошил модем (2.26) и получил такую картину - 1-ая статистика.
После этого попробовал подставить найденную в форуме в аналогичной ситуации строку (добавлено S210.7=1 и без +MS=11) инициализации с попыткой соединиться по v90. Ниже привожу еще две статистики с этой строкой - сначала соединилось по v34, а потом - по v90.
Можно ли в такой ситуации улучшить результат, или все оставить по старому? Спасибо.

Попробуйте такие строки инициализации:

S91=18 S210.7=1 +MS=11,,,,,,14400

и

S91=18 S210.7=1 S17=64 +MS=,,,36000,,,14400

Покажите, что получается в статистике в каждом из случаев.

[Technical Support]

Похоже, от использования V.90 больше вреда, чем пользы. Пропишите такую строку инициализации:

M4 S91=18 S210.7=1 S210.4=1 +MS=11,,,,,,9600

и покажите, что получается в статистике. Во время сеанса связи нужно обеспечить загрузку модема на приём (скачайте какой-нибудь архивированный файл).

Что касается обрывов соединения: модем будет включать динамик во время перетренировок и пересогласований скорости. Интересует происходящее непосредственно перед разрывом соединения. Например, включается динамик и Вы слышите короткие гудки на фоне писка Вашего модема. Причина, скорее всего, в том, что АТС самопроизвольно разорвала связь. В общем, нужно подробное описание услышанного. Ну и статистика, конечно.

Спасибо! С новой строкой получилась нижеприведенная статистика.
А по поводу разъединей, у меня динамик был установлен на малой громкости, но перед рассоединениям слышались какие-то шумы. При последующих соединениях с обеими предыдущими строками разрывов связи не было.
