I tend to agree. The RAD gear we have is really poor in a lot of 
important ways; bad software, bad diagnostics, bad logging.

The one thing I *will* say is that, when up and running, it provides 
fair-to-middling circuit emulation via short-haul Ethernet/IP links, and 
does it without new-fangled clocking like SyncE/1588 (which we can't 
support). However, we had to enable QoS to get priority queueing, 
because it is VERY intolerant of jitter (and loss, of course - I wish it 
had FEC) due to the buffering strategy it uses.

We still don't have a perfect path, but it's acceptable for our needs 
(legacy voice links delivered as cheaply as possible). However, I would 
probably consider other products if I was doing it again.
