интересует такой вопрос,какие занчения затухания являются нормой? где это можно почитать.ссылку если можно.вот показатели снятые моим модемом huawei,насколько далеки они от нормально-реальных?

ps тариф социальный(те скорость ограничена на порту 128 кбс,если это имеет значение)

данные параметры перекрывают ваш тариф в десятки раз

Про параметры линии можно прочесть здесь: http://www.vrn123.ru/wiki/services/xdsl/xdsl_param

вроде как отличная линия :). а нельзя скорости прибавить никак?

вы сами ранее дали ответ на свой вопрос

зы зачем люди спрашивают очивидное...
