Что посоветуете?

[Technical Support]

Основная проблема - перетренировки и пересогласования скорости, запрашиваемые удалённым модемом. Основной метод борьбы - ограничение скорости передачи Вашего модема (т.е. скорости приёма удалённого).

Пропишите такую строку инициализации:

S91=15 S210.7=1 S17=64 S120=11 S55.4=1 +MS=,,,,,,21600

и затем подберите ограничение таким образом, чтобы перетренировок/пересогласований было как можно меньше. В статистике смотреть сюда:

Retrains Issued/Granted/Auto. 0/14/1
Renegs Issued/Granted........ 4/15
