Ed my concern was that since you don't have a different pair for both upload and download, there would be issues when a few users are running uploads at the same time others are running downloads? I suppose a single pair can handle it since speeds of upwards of 3 Megs can be obtained on a 2 wire, but I'm having trouble with calling a single pair circuit a T-1. On second thought maybe it's that I'm having trouble paying for a 2 wire circuit that's called a T-1. argue
