In the outside plant, we use binder group separation, and shielded =

I talked to another tech about this and he made the point that the =

CAT5 or anything else is ratified, shielded is still the STANDARD.
If it's any consolation, we provide frame relay service to many of =

relay switches to our demarcation points.
