debug codes

[cisco_trouble]

I need a link or reference guide to understand the debug codes for ISDN and PPP? e.g.

User TX -> RR sapi=0 tei=76 nr=108

or

INFO sapi=0 tei=76, ns=71 nr=107

or

CCBRI_Go: NO CCB Src->HOST call id 0x8075,

Is there a book or something on debug codes?

Thanks in advanced.
