I spent many hours tonight putting together from multiple sources a
detailed comparison of Red-C versus Redback.
Except in the areas where Red-C is superior, the two products are
identical as peas in a pod.
Red-C offers major advantages of Voice over DSL and extended
hot swapability.
I found NO AREAS where Redback is superior.
No doubt about it, Red-C is a superior box.
As usual, SI's lousy tabular formatting gave me fits.
As always, although I doublechecked my sources, data is presented
on a best-effort basis only.
I hope people appreciate this, as I started on this after supper.
