PPP is the encapsulation used in likely 95% of the ISDN solutions; is there some reason you don't want to use it? Frame Relay and X25 support over ISDN have been in place since 12.1; whichever it is you are trying to get to work, you might ensure that the configs are correct, the version of code you are using is recent, and then have a look at the X25 or Frame Relay debugs, in addition to "debug isdn q931" and "debug isnd event" to see if you can understand what might be going wrong.

Hello,

so exactly ISDN connection is OK , sh int bri0 -up -up, sh isdn stat B1 or B2 OK, sh isdn active OK. IP connection does not works.

At this moment I have temporary solution with cisco 2520 and it works only with HDLC absolutely OK.

Thanx Marian
