Dell,
The C3 is a 12vdc device. Just like 99% of all the other stuff you attach to an alarm panel including the Uplink device. . .right? You keep getting stuck on the internal battery like it is the mandated one and only backup power. Just pretend the c3 is like your uplink . . . a 12vdc device with no battery in it all. Just unplug the battery, throw it away and pretend it never existed. Your uplink is undoubtedly plugged into an aux power supply with its own battery back up and supervision. Just plug the c3 into that. . . now it is supervised exactly the same as an uplink. You must understand, the c3 built-in battery is an optional convenience. . . it does not exclude a supervised power supply/battery backup system in its stead. The c3 is used by some as a home phone. . .not for securirty at all. For them, the built-in battery is a nice convenience.
As I mentioned, c3 could have an internal radio failure or expired minutes and you wouldn't know it until test day. Expired minutes is just your own stupidity and is akin to not paying your annual monitoring co bill, so it doesn't count. Both are supervised in the sense that both co's will annoy the crap out of you trying to get you to pay and if you don't pay it had to be on purpose.
I challenge regarding data only successfully transmitting through a tower that fails dtmf on voice line. DTMF might fail, but it will know it failed and it will repeat if need be. The cellular data can fail just the same, and it will repeat also.. .but it can do it more quickly. But the time difference is not particularly relevant in a residential alarm.
I understand the difference between the data networks and the voice networks. The biggest reason the data system is used is for efficiency. . not reliability. It is a cost thing. The data lines only use the bandwidth they need and can do so using addressing similar to the internet. .. rather than making what would amount to a dedicated tunnel which is what voice does using far more switching and bandwidth. Realize that the biggest customers of these sorts of data connections are not security systems, they are things like vending machines and fleet vehicles. There is also a reasonable chance that my own startup co which monitors bar and restaurant beverage sales may use that technology . . . but at present we are leaning toward the internet . . but this is off topic. If it had to make a voice connection that would be much more burdensome and the cost would be much higher.
