[c-nsp] out-of-band management - modems?

[Tim Jackson]

My situation isn't just WAN routers, but SONET and amplifier sites. We've
ended up going with the MRV LX4000 boxes. We do dry contact alarming with
them as well as serial into amplifiers and other gear. Integrated modem,
supports dial-on-demand, and does console logging. On top of supporting
whatever you could want, it's quite affordable, too.
