I have a bunch of old cisco stuff with BRI ports on it but it was  
never meant for voice, just purely data, so I don't think its very  
useful for this purpose, but some of the basic signalling could  
probably be tested with it.

is exploring some sort of back to back card setup worth looking into  
without committing to a line ? Then at least if a pair of cards can  
talk in the "new format" there is a better chance of them working on a  
real line. This would also have the advantage of being able to see  
both ends of the line for debugging purposes, or put the line in the  
euro mode which should work out of the box just to make sure the  
hardware setup is all valid before making changes.
