i have configured the card and connected it the Taqua switch. Looks like layer 1 is up cause everything greens up . but when i go to LD 96 to check the DCH it is in an RLS AUTO state. everytime i try to establish it , i get an error stating that it is in a wrong state. the Taqua switch is set up as Network and the Option 11c is setup as user. is there anywhere to check the type of isdn protocol that the pbx is using?
