This is true. Apparently the Sage has this dialed in.
Presently most Washington State EAS boxes are using
one port for -polling - the CAP Server. This is a nice way
to do things as it deals with firewalls and eliminates issues
with Static IP's etc. Other systems that the box may be
connected to may well be different. Don't forget that
a station will connect the new box to their network for
a number of reasons.

The bottom line is that there are likely far more stations
that can get Internet access than connect to a system
any other way....That is unless you want to try and
use POTS. The Daisy Chain won't work due to the
thru-put requirement of CAP. I can just imagine how
long it would take to transfer the data in a CAP message
that contained an MP-3 or Wave file using POTS.
Then there is DSL, but with that you have decent Internet
speed...Likely around 1.5 mps.
