Over the years of instrumentation and control work, I've been involved in several Intrac/Moscad/Ace systems, the largest of which is a municipal water and sewer SCADA system that runs 3 water plants, all of the 116 pump and storage tank sites, the two wastewater plants and all of the 60 lift stations, the forced main sections, the stormwater monitoring sites, the 12 weather stations, and does all of it without a piece of oversold, overpriced Allen-Bradley equipment in sight. In fact, it was megabucks cheaper than the proposal that included A-B.
Using Moscad to monitor trunking sites is kinda overkill, but is a natural considering it's a MotherMoto communications product that directly interfaces the radio side. Using Moscad for station alerting is kinda like using your 3 gig computer to blink a light, but again, as a part of a whole system, it makes sense from an operability standpoint.
Sorry 'bout the A-B blast, it's really great equipment, but it's frequently oversold.
