older WIC-1DSU with 2801 router?

Do the old WIC-1DSU cards work with this router or do I need to buy the new
"V2" cards?

Thanks,

Cisco 2800 module compatibility chart does not list the WIC-1DSU

The WIC-1DSU-T1 is supported on these platforms with these Cisco IOS
releases:

Platform Cisco IOS Software Release
1600 11.2(12)P, 11.3(3)T, All 12.x
1700 All Cisco IOS versions
2600* 11.3(4)T1, 12.0(1), 12.0(1)T, 12.1(1),

2600XM 12.1(14), 12.2(12), 12.2(8)T1, 12.2(11)YT

The WIC-1DSU (version 1) cards do *work* in the Cisco 2801 model, but
are not officially supported. That would lead me to believe that some
future IOS might remove compatibility for this card, and you'll be SOL.
Also, any TAC questions for hardware problems are probably going to
bounce back immediately that you are running an unsupported config.

It would be prudent to get the WIC-1DSU-V2 for this router.

On the other hand, the 2811 and 2821 will NOT work with the WIC-1DSU.
They do require that you have the WIC-1DSU-V2 (at least when I ran up
either of them). The code just won't recognize that old card at all.
