[Asterisk-Users] Channel Bank FXS Questions

[tns at cwkb.com]

Here is my question.  We have a Asterisk PBX with an T400P Card.  We have 
2 T1's comming into this card from a Channel bank.  So this gives us 48 
Channels and 48 Extensions.

Here's my issue: How and where do my extensions get punched down?  Is 
there a 24 extension FXS Card with an Amphenol Interface on it?  Or ?  
This is where I am getting lost.  I am used to seeing the Extension Cards 
be handled by the PBX System I am not seeing how this is done with the 
Asterisk System.

I hope this is making sence.  Could someone please shed some lite on this 
subject.

Thank you,

Geoff
