My thoughts were as follows, while you can have a machine with all the
pci slots needed filled with the cards it 
Will be a very interrupt intensive machine. If you were to use 4port T1
cads the interupt load would be signifantly less than by using several
TDM2400 (iirc the interupt load on a 4port is more or les the same as a
TDM2400, with 4 times the capacity)  Heat and power consumption are
always an issue, by 'distributing' the load you will get better heat
dissapation.

I believe the TDM2400 is positioned to replace a wcte11xp and channel
bank configuration with an all Digium solution. For installations that
require 24 ports this is a great clean solution.


The Digium cards that do not use the Tiger Chipset are great, Better
than the Sangoma IMO, My opinion is based on he following: Digium cards
support Digium, narrowmided and stuborn, but an Opinion.  I hope that
Digium continues its design of products such as the TDM2400 and
continues to inprove the hardware as they do everyday.

DISCLAIMER: I don't work for Digium, but use their stuff everyday!!!
