you're thinking of something like the nortel access node express...
doing it this way will also spread the load over multiple asterisk
boxes which may or may not be a good thing depending on the

fwiw, you could also take the telco circuit as a SONET OC3 which,
assuming proper engineering, would put you as part of a sonet ring
and give added redundancy. often the telcos will run an OC3 to
the basement anyways and just peel off a DS3 for you... depending
on the facilities...

to add to john's question, what about the possibility of ATM or
TDM OC3 cards for asterisk? at that point you could probably
*build* an access-node-alike out of asterisk...
