I really wouldn't use the word legacy to describe SONET and OC-3's.
It's around 25 years old (work started in 1985, first standards published in 1988) and we now have a ratified 100G Ethernet standard.
Much of it is being used to transport subrate links, some of which are derived from even older transport standards.
If not legacy, what word WOULD you use?
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
