Psap Interconnect

Structured NG112 reference page.

112 readiness

Policy, location, routing, and response quality connected in one operational model.

Core NG112 Architecture

PSAP Interconnect

The interconnect is where network design becomes operations. It must support emergency sessions, callback, transfer, alternate routing, location display, recording and continuity. Some countries centralize this nationally while others federate regional or service-specific centers.

What it does

PSAP interconnect describes how emergency centers connect to NG112 service networks and adjacent PSAPs.

It provides the delivery path from routing functions into call-handling environments.

How it works

Connects PSAP call-handling systems to emergency service networks.
Carries signaling, media and associated emergency data.
Supports transfer and fallback between PSAPs.

Key interfaces and protocols

SIP
Media/RTP
Location data interfaces
CAD/GIS integration

Systems it interacts with

PSAP
Call handling
GIS
Recording
ESRP

Common failure modes

Media one-way audio
Location display mismatch
Transfer failure
Local PSAP outage without alternate route

Implementation considerations

Design for operational drills, not just turn-up tests.
Include recording and audit in acceptance tests.
Confirm how multimedia and RTT are presented to call takers.
