Carriers using CES in the wild?

[Dave Temkin <dave () ordinaryworld com>]

Is anyone aware of any carriers that are using CES as a transport method
as private line and aren't necessarily selling it as such?  (ie, I've
ordered a DS-3 from point A to point B, and instead of the carrier
dropping it as standard TDM it's CES through their network...)

Thanks,
