It would be ALOT more reliable and ALOT cheaper to use a channel bank.
Besides, DIGIUM recommends  against using more than 3 of it's cards in a
single box.  TDM400P cards are designed for low density applications 
where you might need 6-8 lines.  For 8+ lines, you are much better off
with a channel bank.
