Even backbones are not backbones anymore. Sprint, MCI et al. operate
meshes with multiple internal paths. If you have an average of 8 alternate
paths of OC3c, then you get closer to a 24x multiple of DS3. Of course
it's not really that simple, but I don't think that things are as bad
as they look in your table above.
