NM-4T1-IMA replacement part compatible with Cisco 2851 router

[boatman]

I currently am using a 2621 router with an NM-4t1-IMA module which connect my DSL customers to the Internet.

I would like to upgrade the 2621 with a 2851.  What would be the equivalent network module that I could use on the 2851 to provide the NM-4T1-IMA features ?
