2 Agenda Review Terms What is PS/ALI? PS/ALI providers – sampling 9-1-1 legislation
3 Enhanced 9-1-1 Enhanced 9-1-1 service is for reporting police, fire, medical and other emergencies; it allows the public safety agency to immediately pinpoint the location and telephone number of each caller. If the caller is provided service by a private branch exchange (PBX) or Centrex, the main number and address of the PBX is provided to the public safety agency.
4 PS/ALI Private Switch Automatic Location Identification (PS/ALI) is an enhancement to 9-1-1 emergency response systems that allows PBX and Centrex users to enjoy the benefits of full-featured enhanced 9-1-1, including specific address and location information for each station.
5 Description of PS/ALI Service Allows a PBX switch located on a campus or multi-building subscriber’s premises to be trunked directly in an E9-1-1 selective routing office. Automatic Number Identification (ANI) is passed to the selective routing office by the PBX, where it is read, processed and utilized exactly as if it were provided by any other serving-end office in the E9-1-1 system. With PS/ALI the PBX owner/operator must supply the initial telephone number- to-address data (ALI files) as well as periodic updates. Station information is loaded into the E9-1-1 automatic location/data management system (ALI/DMS) for retrieval by the 9-1-1 PSAP when an emergency caller dials 9-1-1 from a PBX station.

VoIP services may also have PS/ALI – check with your vendor. DSS service cannot be used for PS/ALI trunks
