Another broadband focus is ProCloud, which is also seeing a lot of momentum. This is their managed WiFi offering, built on their Bluesocket acquisition, and they brought in some customers to talk about how it's being deployed. You'd be surprised at the wide variety of use cases, and this is definitely a case where if you give businesses these capabilities, the applications will quickly materialize.
Closer to my everyday focus, though, ADTRAN has moved away from the UC market, and while they continue to serve the telephony space with their NetVanta product family,it's not a core focus at present.
That said, I think their focus on Gigabit broadband is sound, especially for how it helps make their customers - service providers - more competitive for today's always-on end users. Related to this, we heard a lot about another strong focus - NFV/SDN. Again, they're on the right track, but pretty much all the carrier-centric vendors are doing this, so it's hard to say if this will truly differentiate them.
For now, I just have time for these short comments and a few photos from the event. Gotta get back to everything else, but I'll have more to say soon.
