Testing and Interoperability

Conformance, interoperability and end-to-end validation are different. Conformance checks behavior against a specification. Interoperability checks whether independent implementations work together. End-to-end validation checks whether the caller-to-PSAP path behaves correctly in real scenarios.

CONFORMANCE, INTEROPERABILITY and END-TO-END VALIDATION are not interchangeable.

What it does

Testing proves whether specifications, independent implementations and the full emergency path actually work.

Testing turns NG112 architecture from a diagram into operational evidence.

How it works

  • Runs protocol tests for interfaces such as SIP, PIDF-LO, HELD and routing behavior.
  • Exercises multi-vendor paths and PSAP workflows.
  • Validates location, media, failover, roaming and degraded-mode scenarios.

Key interfaces and protocols

  • ETSI TS 103 480
  • ETSI Plugtests
  • SIP traces
  • Location validation
  • PSAP operational tests

Systems it interacts with

  • ESRP
  • ECRF
  • SIP
  • PIDF-LO
  • RTT
  • Resilience

Common failure modes

  • Lab conformance passes but live PSAP workflow fails.
  • Testing ignores roaming or fallback.
  • Location is syntactically valid but operationally useless.
  • Vendors test only their own happy path.

Implementation considerations

  • Build acceptance tests around real incidents and edge cases.
  • Keep packet traces, screenshots and call-taker observations.
  • Retest after software, GIS and routing changes.

Standards

  • ETSI TS 103 480
  • ETSI Plugtests
  • ETSI TS 103 479
