1. Проверьте версию микропрограммы. IDC Diagnostics говорит, что версия 2.06. Это может быть неправдой, если Вы установили более свежую микропрограмму, но забыли нажать кнопочку "Detect modem" в IDC Diagnostics. Если же версия действительно 2.06, то Вам её нужно обновить, установив 2.14.

2. Верните модем в "заводское состояние" командой:

at *nc22 w2 \v1 s95=3 &w &w1

Команду нужно выполнить один раз из терминальной программы. Сделайте это в любом случае, даже если не пришлось обновлять версию микропрограммы.

3. Пропишите такую строку инициализации (в свойствах модема в Windows):

S91=15 S210.7=1 S17=64

и пересоберите статистику.

Сделал все как советовали.
Но скорость увеличилась только до 48 000.
Даю новую статистику. Подскажите, что можно еще изменить?

Сделал все как сказали.
Скорость осталась 48 000.
Может быть еще что-нибудь посоветуете!

[Technical Support]

Похоже, что 48000 - оптимальная скорость для Вашей линии. Вы можете попробовать ещё немного увеличить агрессивность модема (поставить S17=5, но скорее всего, она снизится до всё тех же 48000 вскоре после начального соединения (проверьте по статистике). В этом случае вернитесь к старой установке S17=64.

Понятно.
Спасибо. Попробую!
