Ok..so how would the CALLED and CALLERID ID be presented to Asterisk when
using PRI signaling.

I'm tying a Nortel option 61 to asterisk via T1.  I don't want to split each
of the t1 channels out into individual lines (tied to a specific extension)
- so a trunk in and out.
 
Assuming PRI over T1 signaling, how would I pass the CALLED and CALLER info
across the channels so each side knows what to do?  Is there something in
the PRI protocol you can point me to for figuring this out?
 
Thanks,

That's what the D channel is for.  A PRI is a primary rate ISDN.  B channels
carry voice, D channel handles the information & signalling in ISDN.
