ELI5, How does calling the emergency line connect you to the nearest PD?
In: 3
Landlines are listed in ALI and ANI databases; automatic location information and automatic name information. The locations are mapped to a certain PSAP, public safety access point. That’s the dispatch that answers the call.
Cellular is different as there is no location DB to reference. The call tower is assigned its nearest PSAP and will manage the connection, create the voice path, and hand it off to the assigned PSAP.
