I can't seem to get at pricing there for the unit. But it seems to be
roughoy equivalent in overall useful features - of course it runs the
most bloated comm server OS available - IOS. The major difference is that
it seems to take the same path the RA6300 does - uses analog Microcomm
modems instead of digital modems.
One of our engineers created this.

The following is our best approximation of the transition that Cisco has gone
through to create the AS5200. As you can see the architecture has not really
changed, it has just been repackaged. And of course in the AS5200 you are
still left with the digital to analog conversion and a possible bottleneck
at the async port. The diagram at the bottom shows the PM-3 architecture
in contrast.
