  • Consolidated PSAP: A facility where multiple Public Safety Agencies choose to operate as a single 9-1-1 entity.
  • Legacy PSAP: A PSAP that cannot process calls received via i3-defined call interfaces (IP-based calls) and still requires the use of CAMA or ISDN trunk technology for delivery of 9-1-1 emergency calls.
  • Serving PSAP: The PSAP to which a call would normally be routed.
  • NG9-1-1 PSAP: This term is used to denote a PSAP capable of processing calls and accessing data services as defined in NENA’s i3 specification, NENA NENA-STA-010, and referred to therein as an “i3 PSAP”.
