Помогите улучшить соединение

[SerjAnt]

Подскажите пожалуста как сделать лучше соединение. Стоял модем USRobotics 56k, все относительно нормально работало, сломался, купил IDC-5614BXL/VR, он по несколько раз пытается соединиться, качает с перерывами постоянными. Может быть это драйвер плохо работает?

Для анализа ситуации требуется полная статистика, а не только расширенная. Присылайте, посмотрим...

Сейчас соединение было неплохое, но соединился примерно с 5й попытки.

[Technical Support]

Проблемы возникают из-за того, что модем пытается работать на V.90. Ваша АТС - аналоговая, довольно посредственная, и V.90 ведёт себя не лучшим образом.

Есть два пути:

1. Запретить V.90 и настроить V.34 оптимальным образом.

2. Попытаться добиться лучшей работы от V.90.

В первом случае Вам нужно прописать такую строку инициализации:

S91=15 S210.7=1 S202.3=1 +MS=11,,,,,,19200

Во втором случае прежде всего обновите микропрограмму до версии 2.26. Для установки воспользуйтесь загрузчиком FldrWin/VR, который есть на этом сайте, в разделе "Микропрограммы".

Затем пропишите такую строку инициализации:

S91=15 S210.7=1 S202.5=1 S17=60 S120=6 +MS=,,,,,,19200

Ну что же, вполне пристойно, учитывая "качество" Вашей телефонной связи. Так и работайте!
