I know that this has been replied to, but, where I work, We use the Carrier Access Group Adit 600 Channel banks.
It supports two T1's and my boss tells me that we can get the for about 400-800 dollars.

They use 8 port c\expansion cards, so you can three groups of ports, say 16 FXS (2x FXS) and 8 FXO ports (1x FXO).

These units are programmed using a crossover cable and a serial port.

They have a lot of other features that I don't know how to use, but they work grate for us.

I hope this helps.

(or most) of Asterisk's features and can be installed by a newbie?

I'll search for it on ebay

I'm going to install asterisk with four digium cards.
Can anyone mention a brand that carries boards with 4 compatible
          
pci
  
slots?
          
What 4 cards are you thinking of installing? Most people seem to
        
run
  
into trouble after the second concurrent card.
        
I was thinking one 4 port FXO card
Two 4 port FXS card
And the fourth with one FXO and three FXs
For a total of 11 FXSs and 5 FXOs (for five POTS lines and 11 analog
extensions).
      
You would be far better off going with a channel bank and T1 card.
Immediately you get room for expansion as you won't be limited to just
16 ports. As for cost, 4x $305(I think that is the current price) =
$1220, $1220 - $500(t100P) = $720, or enough left over to get taken on
parts from ebay a couple of times before you reach level costs.

    
What trouble should I run into?
Define trouble? Hard to configure, or impossible because of IRQ
      
sharing
  
issues or whatever?
      
Trouble being 4 x 1000 interupts per second on the machine. Lack of
expansion, interupt sharing, any number of annoyances.

    
Anyways, almost all motherboards put 4 PCI slots on the board as
        
it is
  
not much extra and expected on anything non entry level.
        
I thought so. Apparently most of them only come with three.
I was hoping to locate a motherboard that has five so I'll have room
      
to
  
expand, but four will be great.

Anybody knows if PCI express technology is compatible with
      
Wildcards?
