TE420 card: How to?

Digium TE420 card:

Can I use this card with 4 T1’s on the Asterisk server and configure it as 24 ‘digital extensions’ ?

on the backend the TE420 will be connected and provide signaling to T1 based IVR system, so:

1)-incoming sip call hit Asterisk
2)- Asterssk deliver the call to any port on the TE420
3)- calls is sent to the IVR system (connected to the TE420 card)
