5614BXL/VR+, что не так с настройкой?

[worxone]

Здравствуйте,

приобрёл сабж, экспериментировал с настройками, пришёл к строке:

S91=16S210.7=1

Взгяните, пожалуйста, что получилось (дефолтом было почти так же):

[Technical Support]

А что известно о типе Вашей АТС?

Про АТС мне ничего не известно. Номер начинается на 303 (мск), неспаренная линия, именно на ней сигнализации нет.

Вот ещё немного статистики, снята в самый разгар дня:

При этом строка была -

S91=18S210.7=1

Если сделать S91=9, то с V.90 соскакивает, скорость падает до 28800.

[worxone]

Про ATC узнал - координатная.

[Technical Support]

303 - АТСК (координатная), Перово - Новогиреево. Получаемые Вами результаты весьма типичны для АТС этого типа.

Рекомендуемые установки:

S91=20 S210.7=1 S17=64 S202.5=1 S120=8

Попробуйте, покажите статистику.

Спасибо. Чуть лучше. Ещё подтянуть реально?

[Technical Support]

Вы можете поэкспериментировать с фильтром низкочастотных помех (выключить его с помощью установки S55.4=1). Врядли это улучшит ситуацию, но попробовать никогда не мешает.

Увеличить скорость начального соединения до 38667 можно, поменяв S120=8 на S120=9. Естественно, увеличиваться она будет не всякий раз, а только в тех случаях, когда качество связи будет чуть лучше, чем в приведённой Вами статистике.

А в общем, Вы уже добились всего, что можно на Вашей линии.
