помогите настроить IDC 5614BXL/VR+

[Viper]

OS - WIN XP, микропрошивка 2.23. Проблема довольно банальна - очень плохая линия. Подскажите как сделать связь более стабильной, скорость неважна. Пробовал соединяться на V.34, но довольно часто происходит разрыв связи по причине RETRAIN FAILURE. Вот статистика одного из соединений:

Переходите на V.34, а там будем смотреть, что за разрывы связи. Строка инициализации такая:

S91=15 S210.7=1 +MS=11,,,,,,21600
