I've been listening to the new dispatch center for Carrollton, Addison, Farmers Branch & Coppell lately and it seems to be much busier than all of those four cities were when they had their own dispatch centers. I like that they have distinct tones for each type of call, makes it easier to listen for structure fires. The only thing I'm trying to figure out now is the box numbering system. For those who used to follow Carrollton, they had an elaborate box map that has been replaced with a uniform system. But I have yet to find a pattern, like the first number corresponding to the city or something like that.
Another interesting thing is that the tones for FD are also apparently separated by city. On calls where another city is dispatched for mutual aid, a separate tone is sounded for their stations. A single tone set can open up the speakers for any combination of stations in Carrollton; but if Engine 131 from Farmers Branch needs to respond on the same call the tones have to go off again for those station speakers to open. Makes it a heck of a lot easier for the address of the structure fires to be heard. If units from Carrollton, Addison & Farmers Branch respond then it will be dispatched three times.
I'm also curious as to why Coppell joined this system. The bulk of their mutual aid has been to/from Lewisville, Grapevine and Irving. Coppell and Carrollton do share a border, but the population center of Coppell is such that those other three end up being closer to the bulk of the calls. Coppell used to be on Lewisville Pub Safety TRS, which made sense for the mutual aid aspect. Not sure why they would leave that to come to this system.
