I don't know of any channel banks that accept PRI.  Channel banks take in 
regular T1s (and E1s if you can find 'em).

If you had a standard CAS-signaled T1 you could, yes, bring it directly into a 
channel bank and do what you're asking.  That's what they were designed to 
do.  :-)

You would need an add/drop CSU/DSU (something that takes multiple T1s and lets 
you route the individual channels amongst the ports.  Some channel banks can 
do this, and a TE205P can do it too with Asterisk.
