Help with PRI Debug

I am on a learning curve with PRI setup, its the first time I have needed to use a PRI. I am not finding very much literature on interpreting PRI Debugs, could anyone point me towards some reading on the subject?

Why don’t you tell us what you are trying to accomplish PRI intense debug is really a developer level command and should not need to be used as part of a normal PRI integration.

I like to understand how things work when I use them so I want to understand the D channel stuff that is flashing backwards and forwards.

There are at least 1/2 dozen protocols running across the D channel. You could spend a semester in college studying ISUP and still not even scratch the surface.

There are several copied of this old textbook available in the Amazon bookstore, it would be a good start.
