You will need a min of IP plus software for supporting this module.

The module u need is NM-1A-T3

Min memory requirements for the above configuration that you have (2 port serial ) and 12.1(3r)T2 IOS, you ll need,

48 MB of system ram, you already have 64 mb. (20 percent memory allocated for IO - "memory-size iomem 20" command in global configuration mode required (also requires reload to take effect)

You have got enough flash too (32 Mb, required amount is 16 mb)

If you are upgrading to 12.3 IOS, (IP Plus minimum), then you will need 64 mb ram, 10 percent memory allocated for IO.

Hope tht helps!
