FYI you can go to the cad page and see which units are assigned, just an example up here in Orange county, I worked fas a dispatcher for Both Rural Metro ambulance and Orange County Fire Rescue, Each station has a printer as well as station tones, rural metro HQ on old winter garden road has a printer in the communications center, when a call requiring rural metro was being dispatched a generic rma unit was assigned to the call, this in turn would send the call to rural metro over the printer, we would enter the info into the CAD from that printout, now we were talking about setting up a direct feed into the Rural metro cad bypassing the printer but i do not know how far that went.
now this is just Orange county, but sunstar has been an institution in Pinellas for a long time, i have a couple of friends who worked there, but this might help some people know how some comm centers work
