Ситуация такова:
NEAX IPS2000 был подключен к другому Nec'y по CCIS, используя платы PN-30DTC-C (DTI) и PN-SC00 (CCH)
Потом АТС перевезли и возникла задача подключить АТС к Cisco 3662

Было решено поставить вместо PN-SC00 (CCH) плату PN-SC01 (DCH) и подключить к Cisco по PRI

Сейчас, судя по индикации на платах, поднялся 1 уровень потока, но нет D-канала.

Администратор Cisco утверждает, что ошибка идет от АТС:
*Mar 25 10:59:24.070 MSK: ISDN Se6/1:15 Q931: Ux_DLRelInd: DL_REL_IND received from L2

Кто-нить подключался к Cisco по PRI? Что мне проверить?

Тех. условия на подключение от Cisco:
framing NO-CRC4
pri-group timeslots 1-31
isdn switch-type primary-net5
АТС подключается Slave`ом, синхронизация со стороны шлюза Cisco 3662.

Настройки NEAX:
переключатель SENSE PN-30DTC-C (DTI) = 04
переключатель SENSE PN-SC01 (DCH) = 05

а 050 для PN-SC01 (AP05) прописана?
(пардон, не заметил, смотрм дальше )

Ситуация разрешилась.
NEC стоит в другом городе, рулил им удаленно
Т.к. мыслей не было никаких, решил просто перебрать все возможные значения в команде AA06, где встречается слово ETSI. Возле АТС сидел сидел человек, который там отвечает за связь и по моей команде переключал тумблеры MB на обеих платах потока для перезапуска плат
При значении AA06>05:30 вдруг загорелся LC на плате PN-SC01
При этом техник признался, что "пошевелил" плату в разъёме
Вызовы через поток все равно не проходили и я вернул первоначальное значение:
AA06>05:24
И, о чудо! после перезапуска плат D-канал поднялся и звонки пошли
Все таки телефония - наука о контактах

Проверьте прохождение голоса через старшие 15 тайм-слотов потока с нэка на Cisco. На всякий случай)
