I'm passing on my thoughts after recently installing three 360-80 Channel Banks to support some of our "channelized" T1s.

We're using the 360-80s in leu of our PG-Flex systems. They're extremely flexible, easy to install and configure, and work great [our use = 1 channelized T1 in..24 individual/analog lines out].

I'd recomend these to anyone considering new channel bank systems.
