Don't forget this will be ami and not b8zs.  You have to use esf to get
b8zs.

Yes, you will need to emulate the function of the channel units in the
channel bank.  I would ask if the channels are loop or ground start. That is
not obvious from the type of channel unit.

I have not worked with that, but your dial plan then would just take the
incoming digits and do something with that information.  I have no
experience with DID to help with that piece.

It will be somewhat different when you go to ISDN, btw.
