[Technical Support]

Статистика вполне достойная, перетренировки исчезли, количество пересогласований скорости существенно сократилось. К сожалению, в этом сеансе связи Вы почти не принимали данных. Попробуйте организовать сеанс с интенсивным приёмом (скачайте что-нибудь нужное или ненужное )

[Роман]

1 Как уменьшить локальные пересогласования?
2 Из-за чего могут возникать Retrains Auto = 44?(достали они меня )
Вот статистика: (хотя тоже интенсивность соединения не высокая, толька в конце метров 20 скачано подряд )

Сеанс связи длился 517 минут. За это время было, в общей сложности, 50 перетренировок (т.е. реже, чем 1 раз в 10 минут). Это вполне нормально. Пересогласований было всего 110+26-44=92, или одно за примерно 5.6 минуты... очень неплохо, учитывая нестабильность качества связи!

Пересогласования скорости вызваны именно этой нестабильностью. Иногда модемам не удавалось завершить пересогласование, и тогда выполнялась перетренировка (они отмечены как Retrains/Auto в статистике).

Уменьшить их количество при данном качестве связи не удастся. Если источник помех находится в пределах досягаемости, то Вы сможете улучшить ситуацию. Попробуйте отключить параллельные телефонные аппараты. Если есть возможность, заземлите компьютер.

Можно ли запретить локльные пересогласования снизив скорость(v.34b )?

Источние помех 100% на самой АТС, ни как их не получается убрать.
А вот и еще статистика для размышления:
