For which purpose? Callmanager, CME, generic H.323 / SIP ? Which country / switch type ?

You can anyway search for basics of configuration on CCO with "configuring ISDN BRI"

Hope this helps, if so please rate post!

Hi Shen,

Just to add a note to Paolo's good info, here is an excellent doc that shows some good diagrams, cable pinouts and sample configs;

Configuring Network Side ISDN BRI Voice Interface Cards

Hope this helps!

Rob that is a great doc, but let's hope that "04429..." doesn't end with a crossed cable to the NT and trying to power it! :)))

I think that i have done it before you write your comment here :(

Nothing bad should happen.

Now, when you plug isdn into console port, that's another story :)
