Deploy * as PBX

I want to deploy asterisk as PBX and i want to know wicth digium card will match my need.
this is my senario:
2 phone line should be connect the server one for incoming call and the second for incomming fax.
and analog phones should be connected for internal user. according to cost of card i want a card that hold either 8 or 16 or 24 or 32… analog phone.

I’want to know the reference of cards that mach my need so i can evaluate the cost of my system.

Best Regard.

for that many analog connections up to 24 you could use the TDM2400 see link if you need more then that you would probably want to look at a T1 card and a channel bank … gcards.php
