Both paths get a landline call to the right PSAP today. What changes is the test a service order has to pass, and that decides what has to happen before an i3 CHE goes live or an FCC Phase 2 request is made.
A civic address isn't a place on a map until your GIS can match it. Here's what the LVF and ECRF need from your address points and road centerlines before civic-address calls can route on i3.
Of the GIS layers that route 911 calls, the PSAP boundary is the one to finish first. It's the feature you can build, deploy and start routing most calls on while the rest of your data is still being cleaned up.
NG911 GIS programs often treat every layer as a prerequisite for cutover. Call routing depends on a short list that has to be close to perfect first; everything else needs a date, not a pass.
One AI question moves agency data through six places in about thirty seconds. Here is what happens at each step, where the risk sits, and what to configure, contract for, and train on.
Most AI questions in public safety get asked quietly, after the meeting. Here are plain answers to the ones people are embarrassed to ask, and the questions to put to any vendor before your agency says yes.
What if an AI agent could assemble the location information responders need at the moment of a call? The opportunity, the limits, and why every answer needs a traceable source.
The LVF and the ECRF are two functions reading the same GIS data. The LIS holds a different record entirely. The small gray cylinder at the bottom of the diagram decides whether any of them can be trusted.
Three federal rules each assign a piece of the same 9-1-1 location record, and none of them references the other two. The failure mode is not a gap in the rules; it is that nobody holds the whole chain.
