What you can do is (if you are important enough) apply for TSP =
(tsp.ncs.gov) in conjunction with provisioning of a circuit to actually =
have this type of engineering happen and persist, including emergency =
restoration. If your local carrier doesn't offer the redundancy you =
want, your only other choice is to build it yourself. Considering the =
cost of lighting a 10G or 1G strand of fiber for 10km or 20km, working =
with a BRI isn't that important anymore.
