V 34 мало, а V90 много, существует компромисс?

[Andrey1973]

Добрый день!
Просмотрел 15 страниц форума в надежде как-то настроить модем на оптимальную скорость и не морочить Вам спину с глупыми просьбами,, но только убедился в Вашей профессиональности и обязательности моего гласа о помощи. есть некая линия, где V 90 постоянно переретрейнит, а V34 работает аж бегом. Можно найти что-то среднее?

Статистика за 6 часов 40 минут, скачано архивов 86 мб, инит строка
+MS=11. Не снял расширенную статистику, это плохо, но уж так получилось, могу переделать.

Такая-же инит строка, только долго сидел на линии, но постоянные переретрейны, в конце тот модем после сплошного писка бросил трубку, а мой 20-30 сек пытался с короткими сигналами снюхатся.

Заранее большое спасибо.

[Technical Support]

Среднего ничего нет, но создаётся впечатление, что Вам стоит попробовать побороться за V.90.

Начнём с вопросов: что известно о Вашей АТС, какой серийный номер и дата выпуска Вашего модема (это - в гарантийном талоне) и заземлён ли Ваш компьютер?

Цифровая АТС, серийный номер и дата выпуска модема - 05.10.04, 226-994231. Компьютер не заземлен, заземлю на следующей неделе. Но включение фильтра помех в модеме ничего не дало, хорошую, среднестатическую по ретрейнам и длительную по временя статистику соберу в понедельник, тогда же и выложу.

Спасибо.

[Technical Support]

Получаемые Вами результаты нетипичны для цифровой АТС. Либо АТС не успели толком настроить, либо проблемы с медью (Вы очень далеко от АТС, затопленные колодцы и т.п.), либо что-то "шумит" непосредственно у Вас в квартире.

Поэтому неплохо было бы навести справки у соседей, как работает у них.

Пока же пропишите в строку инициализации такие команды:

M4 S91=18 S210.7=1 S55.4=1 +MS=,,,,,,19200

Теперь, кроме всего прочего, модем будет включать динамик во время перетренировок. Попытайтесь послушать и понять, какого рода шум мешает связи ("треск", "булькание", "посторонний разговор" и т.п.).

АТС цифровая, но кабеля никакие, райцентр. Мы несколько раз меняли пару пока нашли подходящую, до АТС 4 км.
Компьютер НЕ ЗАЗЕМЛЕН!!!
При касании корпуса компьютера индикатором – он СВЕТИТСЯ.
Не ругайте сильно, сам в шоке, срочно делаю заземление.

При V 90 есть разные постоянные переретрейны , и на 5-7 сек как электрическая дуга и короткие, пшик и все, и чуть длинее пшики. Длинный ретрейн один на 5-10 коротких.

При вышеуказанной строке модем с 3-4 раза соединился на 19200, это его статистика…

Ситуация понятна. Бороться за V.90, наверное, большого смысла нет - производительность будет ниже, чем на V.34.

Попробуйте такую строку инициализации:

S91=10 S210.7=1 S210.4=1 S202.3=1 +MS=11,,,,,,19200

Все, заземлил!!! Ура!!!.
Но с Вашей строкой инициализации модем поет песни и все, из 10 раз 3-4 он сконектился на пару минут, работать из-за ретрейнов было невозможно.
На строке +MS=11 закачка зашкаливает. В flashget идет ровный без всплесков график. Явно можно и больше, хотя может это уже идеальная скорость.
Чистая строка инициализации позволяет сконектится на V90, но не работать.
Статистика ниже. На праздниках работал с Zyxel 56 Pro, ничем не лучше.
Может можно не 33 а 40-42 и не выше, может Вы с этой строкой оглушили его немного.
Вобщем что-то посоветуйте, пожалуйста, уж очень интересно, чем это закончится.
Только что приходил знакомый (абзац назад) говорит IDC ерунда, много провалов в работе. Я думаю, что уже смогу ему помочь

Ладно, хотя я думаю что доходила, потом попробую еще раз.
По поводу новой строки - ЭТО БОМБА.
За 7.30 скачал 109 Мб, в час получается 14.5 мб архивов. При V34 получалось 12 Мб. Явный прогресс. Ретрейны есть, не очень часто, но на фоне увеличенной скорости они нивелируются. Мне понравилось.
Думаю, может поиграться с мощностью передатчика или все оставить так как есть?
