Asterisk DAHDI yellow alarm

Доброго дня, уважаемые! Создал аналогичный тред на asteriskforum.ru, однако там тишина :( Есть следующая система:

Linux asterisk 2.6.18-238.19.1.el5
Asterisk 1.8.5.0
DAHDI Version: 2.5.0 Echo Canceller: HWEC, MG2
libpri version: 1.4.12
Digium, Inc. Wildcard TE410P/TE412P quad-span T1/E1/J1 card 3.3V (rev 02)

Сейчас в span 1 стык с Panasonic TDE-200, span 2 - поток оператора 1. В TDE-200 сейчас E1 второго оператора. Пытаюсь переключить поток оператора 2 в Asterisk:

Подключаю поток оператора 2 в span 3:

Пробовал оставлять только один поток второго оператора и от него брать синхронизацию, патч-корд проверил сто раз (http://support.red-fone.com/downloads/tools/T1-E1CrossoverCable.bmp). Вставляю обратно в панасоник - тут же все поднимается. Единственное - от мультиплексора до панасоника - 1 метр патчкорд, а до Астериска метров 30 кабеля (пробовал через него подключать поток провайдера 1 - все работает). Уже не знаю что пробовать :(

Куда копать то?

Спасибо.
