Leased lines offer something that is impossible to do with digital
communicators: Line security.  While this isn't critically important
to 99% of alarm users out there, it is very important to customers who
need intrusion detection systems the most.  Two-way supervised radio
is subject to frequent service outages in some areas, and network
communicators are exactly as unreliable as the computer network that
they are connected to.  I was speaking to a DSS rep  eariler this week
about this very issue.  It's a problem.

Before any of you ask who DSS is: see www.dss.mil
