Private Switch/Automatic Location Identification Service (PS/ALI)

Make Sure Emergency Services Know Where You Are
with PS/ALI

If your business or organization is located on a large campus or multiple locations, your system might not be able to identify specific location information to emergency agencies when a caller dials 9-1-1. And that can be the difference between a good or disastrous outcome. PS/ALI is an enhancement to 9-1-1 emergency response systems that allows you to enjoy the benefits of full-featured Enhanced 9-1-1 (E911) if you're a private branch exchange (PBX) and Centrex/Centron customer. This means that the E9-1-1 operator can direct emergency response personnel to your correct address, building, floor, room, or cubicle.

How It Works

The PS/ALI service allows private switch owners to connect directly with the 9-1-1 network. This enables management of station locations with precision, accuracy, and specificity down to the floor, room or even cubicle level. When a PBX customer with direct inward dialing (DID) or a Centrex type system enters into an agreement to subscribe to PS/ALI, they work with the 9-1-1 public safety answering point (PSAP) to load specific station telephone number information and address information into the 9-1-1 database. Once the trunks to the 9-1-1 network are in place and the information is loaded into the 9-1-1 database, all 9-1-1 calls placed from the impacted stations are routed to the appropriate PSAP. The station information is then displayed to the PSAP, which automatically knows from which building, floor and room number the call is being made. Emergency vehicles are then dispatched appropriately.
