[cisco-nas] 3640 + NM-30DM vs. AS5300

[Aaron Leonard]

Gert,

The 3640+NM-DM (MICA modem NM) doesn't support *everything* that an
AS5300 with MICA modems, but certainly most things.

Off the top of my head, what the 5300 can do and the 3640 can't are:

- Call Tracker

- Modem pooling

- Resource Pool Manager
