asterisk users - Aug 2003 - Hardware for a Big PBX

Hi list...

  I have already installed a small PBX ( 1 FXO (E100P) and 4 FXS (TDM400P) ) 
but now i want to know how to build a bigger one... maybe 8 FXO and 24 FXS 
something like that o bigger.  But i dont know witch hardware i need. 

  And also any of you have installed Asterisk only for VoIP and connect this 
with a Normal PBX (Nortell), so that the actual telephone system can dial to 
the Asterisk and this system can recive call form Asterisks.

use a
-1 t410 4 t1 spans
-32 ports off a channel  bank(s)
 -1 CAC adit 600 with 3x8fxs cards & 1x8fxo cards
   OR
 -2 adtran ta-750/850
     1- 6x4fxs cards
     1- 2xfxo cards
-how much box depends on how much VoIP your doing & which codecs
you'd be pretty safe with an intel MB, 2.4Ghz, 256 RAM

then you just need you fav analog phones the adsi aastra 480's are nice
