Need help with digium cards

Hi, im looking to set up a card on my asterisk box, to act as a T1 trunk, but i am a noob regarding this type of cards, im gonna connect another server that will use analog telephones, but will get the service from the asterisk pbx, which is connected to 2 SIP trunks, i will post the requirements of this server, any help would be greatly appreciated, thanks in advance for you help.


This requires 3 full T1 lines
