We are in the process of replacing our aging 3640 supporting one of our secondary internet links. The 3640 was put into place several years ago just because that is what we had on the shelf and the link is only a T1. We are trying to decide between a 2800 series and a 3800 series replacement. Since this is simply a "backup" link with a T1, We are thinking that the 2800 series would be ok since they do well up to about 6Mb of bandwidth.
We are looking for opinions and/or comments as to whether or not this platform will sufice or should be just step up to the 3800 series we use for our large corporate links?
