We bought a 2651XM with only two FastEthernet ports. Now I am planning to bundle two T1's using MLPPP with this router.
I was told to get two WIC-1DSU-T1-V2.
1)Is this supported in 2651XM? or does it depend on the IOS?
2)What are the differences between WIC-1DSU-T1 and WIC-1DSU-T1-V2 modules? The V2 module is bit expensive. I want to know if I will miss anything if I go with WIC-1DSU-T1 for MLPPP.
3) How about VWIC-2MFT-T1?
