What you describe is a folded ring and is indicative of either a =
temporary
solution or bad network design. As a rule, phone companies and capacity
suppliers build very robust systems. =20

The
perfect example - a few years ago when I was a network admin, the whole =
NOC
where the bulk of our T1s were went out suddenly one morning. We =
discovered
that less then a block away a fiber seeking backhoe dug right through =
the
fibers - both the primary *and* secondary fibers - because Verizon =
burried
them both in the same trench rather then run them separate routes. So, =
the
supposed redundancy went right out the window.
The phone companies really aren't helping the situation one bit by doing
stuff like this.
