Q: How does a PM-3 support 60 modems in a dual PRI environment? You run
clear out of channels before modems :)

Yeah, they do that in software versions 4.6Bi12 onwards. 4.6C is the
latest official non-beta release with it.

A full rack w/ 72 digital modems and 4004 chassis is about $33k to an ISP.
I've purchased a couple at that. (non PRI right now, dialins are
channelized T1)

I love the story one of my colleauges told me, when the MAX was used in a
POP and the T1 died. The MAX then dialed out over the PRI to maintain
connectivity, bringing up Bs as needed. Very nice.
Love integrated boxes :)
I'd seriously look at the PM3s. Two downsides I see: lower density and
neato helpful software features. (and needed ones, like OSPF :) Upsides:
smaller/faster/stabler software and lower cost.
What processor is in the PM3s? I see overall higher throughput on the
MAXes, with their fast RISC processors and digital modems, than on PM2s
with Microcoms. (Plus I've never had to undo a wedged modem on the MAXs :)
