IDC5614bxl/vr+ vs. Winmodem

[Dreyk]

Здравствуйте господа.
Модем IDC-5614bxl/vr+ у меня уже давно, попытки подстроить его под свою линию не увенчались успехом. Попытка вылезти в Инет и загрузить простую HTML страничку превращается в долгие полчаса. Грешил на свою линию пока не попробовал дешевенький Winmodem(Agere), а Hayes Accura 33600 (Дешевый Роквел) вообще превзошел все ожидания. Так вот может кто подскажет, как сделать так, чтобы IDC работал хотя бы на уровне Agere ? Статистики с Winmodema и IDC прилагаю ниже:

Давайте будем действовать в такой последовательности:

1. Если компьютер не заземлён, то:

а) Заземлите его

б) Если заземлить невозможно, отключите заземление от модема. Для этого откройте пластиковую коробочку разъёма кабеля, которым он включается в последовательный порт модема, и отключите провод, припаянный к металлическому корпусу разъёма

2. Пропишите в строку инициализации команды:

S91=15 S210.7=1 S17=64 +MS=,,,38667,,,14400

и покажите, что получается в статистике.

Прежде хотелось бы поблагодарить Вас за столь скорый ответ и проявленное внимание к моей проблеме.

И так, «лед тронулся», провод заземления на модемном кабеле не подсоединен (самолично когда-то отрубал).

Статистика выше снята в утреннее время (АТС не нагружена) и вроде как все значительно лучше, по крайней мере, раньше такого не наблюдалось. Но вот днем соединиться удалось с пятого раза, при этом вот чего получалось:

Если возможно, то хотелось бы поподробней узнать о состоянии линии или все банально – модем «испугался» низкочастотных помех на линии c быстро меняющимися хар-ками?

Есть еще одна проблема не соединиться никак с удаленным модемом. При поднятии трубки удаленным модемом удаленная АТС посылает в линию какую-то трель, локальный модем, с жалобным свистом, виснет наглухо , Winmodem как-то с этим справляется. Как победить это?

Да уж, ИЗВИНИТЕ, прокололся. Не знал, что фильтр работает только на высоких скоростях. Возможно, мне это только показалось, но на то оно и есть мое чисто субъективное мнение пусть притянутое за уши. Зато Вы высказались, что думаете по этому поводу (т.е. не сухой строкой инициализации).
