Sounds like you're talking about 7018, not 7132 (SBC), and even 7018
is doing okay for capacity now that its high-traffic customers
(Comcast) are moving traffic elsewhere.
Do you have any specific data to share with the NANOG community
supporting of these claims?

Likewise, I'd be interested in implementation specifics of how a
network of AT&T's caliber could implement backbone redundancy and TE
with static routing. Any data you could share would be extremely
helpful.
