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.

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 subscribers 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.

  multiple terminations of the same telephone
  number (i.e., key systems).
