The Journey to Cloud Native
Looking back at what these guys paid for everything is like a bad dream. It looked weird then but nowadays, wow. Of course the Cascade/Ascend building is a ghost town nowadays -- the CBX500 was a great workhorse, but it's losing steam fast due to Lucent's decline. Stinger still has its fans, but you can get quite a deal for them on the used market.
Zhone's ex-NT UE9000 looks like it competes head-on with Lucent's AnyMedia. I know of a few out there but I doubt it's seen widespread deployment.
