I'd start calling it legacy when it's as easy to order from your telco as X.25 would be. I still see Ethernet circuits delivered via OC-3/STM-1 today with an Overture. If you're throwing OC-3 into the legacy bin you might as well call OC-192 and OC-768 legacy as well. Big deal if the standard is old, apparently it's still useful enough that there isn't a replacement yet. ~Seth
