We have a Cisco 2610 router which only handles one T1 right now. We wanted to add a second T1. So we got a new card WIC-1DSU-T1-V2 and plugged that in W1 slot.

When I run show diag I can see the card but it does not appear on the running configuration.

The other card: WIC-1DSU-T1 right now it is working just fine.

How can I use the WIC-1DSU-T1-V2 on this router?

Here it is what I get

Gentian has posted this same question on the LAN Switching and Routing forum where it has generated quite a few responses (which include both suggestions made here). I suggest that any further discussion of this question be consolidated in the LAN forum.

That is right. I thought WAN it would be a more appropriate place than LAN to post such a question.
