Помогите пожалуйста настроить модем 5614BXL/VR+

[Dennis]

Раньше модем работал на старой прошивке и подключался то на 36, то на 38 кбит/сек.
Из-за слабенькой линии очень часто передача данных останавливается.
После того, как была поставлена новая прошивка, стал подключатся только на 32 кбит/сек , при следующей статистике:

Что можно с этим поделать?

Заранее благодарен!!!

[Technical Support]

Попробуйте прописать такую строку инициализации:

S91=20 S210.7=1 S17=64 S120=6

и покажите, что получается.

[Technical Support]

Скорее всего, Вам просто не повезло, и качество установленного соединения оказалось хуже, чем в прошлый раз. Если такая ситуация стабильна, то Вам стоит попробовать перейти на V.34, дописав в строку инициализации команду:

+MS=11

(либо подождать обновление микропрограммы, ожидается выход версии, которая должна существенно снизить количество перетренировок в Вашей и подобных ситуациях).

Прописал строку. Модем подключается только на 34,6 кб./с.
Поначалу работает еле-еле с большими перерывами(около 5 мин.), затем стабильно "держит"(мин.10), и т.д.

[Technical Support]

Модем соединяется на 34667 потому, что скорость начального соединения ограничена (S120=6). Думаем, что оптимальная скорость для Вашей линии примерно 37333-38667. Соответственно, можно изменить значение S120 на 8..9.

Дополнительно, попробуйте ограничить максимальную скорость до, скажем, 40000 бит/с. Итоговая строка:

S91=20 S210.7=1 S17=64 S55.4=1 S120=9 +MS=,,,40000,,,24000

Но всё это подходит для текущего состояния линии (более-менее спокойного, "ночного"). Днём, скорее всего, придётся ограничиться V.34. Для этого замените данную строку на:

S91=20 S210.7=1 S17=64 +MS=11,,,,,,24000
