[j-nsp] ACX5448 & ACX710

[Aaron Gould]

I've had an ACX5448 in my lab on loaner for over a year.  I need to refresh
myself on how well it performed.  I have the little-brother ACX5048,
probably 50 of them all over my network doing quite well.  Pretty sure those
are not Trio based.

Never heard of the ACX710, but see it in slide 22 here ...

ACX710 and ACX753.  I'm curious about interfaces and modules and
capabilities of both of them.
