Астерискеры,нужна помощь. Заранее извиняюсь за большой объем текста.

конфиг астера:
Asterisk 1.4.25.1
libpri-1.4.10
dahdi-linux-2.1.0.4
wanpipe-3.4.1
Sangoma A-102

Поднят pri транк с definity. Со стороны астериска -g703, воткнутый в sangoma A102, со стороны definity амфенол. Обжато все верно, кабель целый. Канал pri периодически падает, причем никакой закономерности нет- может разваливаться каждые 5 минут, а может раз в неделю.

P.S.
пробовал кольцевую розетку подключать к карте A102, лампочка горит красным. Подскажите как можно еще проверить физику канала.

у меня аналогичная проблема была с ipldk
астериск стоял между провайдером и АТС
оказалось дел в том, что неправильно выставил сигнализацию - 4ess вместо euroisdn. это работало, но периодически валился канал то к лыже (на ней и стоял 4ess) то к провайдеру, бывало даже астер вис.

астер - подключен к моей же АТС, qsig выставлен на обоих концах.

Подскажите кто-нить, какие утилиты в dahdi стоит использовать, чтобы протестировать физику канала. нашел утилиту dahdi_tool, запустил loop. И совсем непонятно, как расценивать результат, ибо его попросту нет - утилита на минутку задумывается и больше никак не реагирует.

Чем можно посмотреть что происходит в канале. Что-то наподобие tcpdump. У меня пока из опыта работы с астером - 3 дня, книжка AFOT и чтиво форумов, самому победить проблему не удалось - прошу помощи.
p.S. Забыл сказать - длина витущного кабеля - около 20 метров.

посмотреть можно pri set debug span 1
Год назад стыковал астер с панасом оп qsig, долго мучался, думал астер глючит. оказалось - плата панаса неисправна.
Проверь плату аваи
