The 7830R is a two way radio.  The network polls the radio at a
programmable interval which you select, including one option that detects a
loss of communication within six minutes.  The radio is expensive, and the
monthly fee is also quite expensive, even more so if you select that six
minute option.

The more frequent polling also requires a very strong radio signal in order
to work properly.  Radio reception varies throughout the year, meaning it
might work fine today and then start causing problems a month from now.
Those problems appear as frequent comm fail/restore signals.  Sometimes,
this simply can't be fixed.

The radio is only a four zone radio.  It does not do Contact ID data
transmission.
