I've got a PM2e-30, PM2e-25, and recently (three months ago) added a =
Computone PowerRack-64. I like Livingston, but I can't say anything bad =
about the Computone. It's slightly more difficult to configure, but not =
terribly so.=20
The Computone doesn't have flashable memory, so if you need to install a =
software upgrade you have to set up a TFTP server for it to download =
from upon power-up, or call Computone and get a new ROM chip. TFTP was =
no big deal as we already use it to maintain backups of all =
configurations for all our devices, including Computone, Livingston, and =
Cisco.
I haven't tried their new ISDN option yet, but plan to. As far as the =
PM3 goes, I haven't used one yet, and probably won't until they support =
T1 for incoming lines in addition to PRI.
