I currently have a Cisco 2801 Router that has one T1.  We need a larger internet circuit, so our ISP said they can bond seven T1's together to give us 10Mbps Circuit.  Now my question is will the 2801 support seven bonded T1's?  Right now I have one WIC-1DSU-T1-V2 card in the Router.  To support seven bonded T1's what type of interface card will I need.  I have never dealt with bonded T1's before.  Thanks.

IIRC, the 2801 can support 2 VWIC3-4MFT-T1/E1 modules (which are 4-port T-1 cards).

Are you sticking with T1 for the purposes of SLA? Are there any Metro L2 services available? Much more cost effective then several T1's, unless however the ISP is giving you a good deal.

Yeah, the ISP is giving us a really good deal due to all the business we give them.  So from what I understand from donjohnston comment above the 2801 router can support up to 8 T1s, but I would need to purchase 2 VWIC3-4MFT-T1/E1 modules for the router.  Is this correct?  Thanks.

From what I am reading the VWIC3 cards are only supported on the 1900, 2900, and 3900E series platforms.  Is this right?

Dang! Nice catch. It looks like the 2801 will only support at most the VWIC2-2MFT-T1/E1. This mean you would need 4 of these cards. At least Cisco's site say's it doesn't support the VWIC3.

Still makes me wonder why the 2801 couldn't support the VWIC3? Maybe if requires more resouces that the 2800 don't have, but I can't imagine the 1900's having that much more horsepower than a 2800 series router. You may want to run this by Cisco to verify.

I just found out from the ISP that they are providing a Netvanta Box that will bond the T1's and then give me an ethernet hand off to my Cisco Router.  The problem is that my 2801 router only has two fast ethernet interfaces which are both is use.  I can install another HWIC card with FastEthernet internfaces on this router right?
