I'll bet. :-) > In general, if copper is available into a building, the telco is going to > look very seriously at the possibility of using that.

So we don't pay a lot of attention to "Tx and Rx in separate jackets, or shielded" anymore?

Cat 3 is optimistic, IME. Cat 2 is good enough for T-1, though; I looked once. > Suite 214 wants a T1. There's already a 25-pair going up there from the > RJ21X.

True. Your netmon link is 404, BTW. Cheers, -- jra -- Jay R.
