Slide8 l.jpg

Why V.18 Conformance testing is Important

  • Specified in V.18 Recommendation Appendix 4

  • Ensures interworking between textphones

  • Small volumes and lack of competition between textphone manufacturers means they are not subject to the same market forces to ensure interoperability.

  • Benefits the deaf and hard of hearing

    To maximise the benefits of V.18, all features should be implemented - automoding, all compatibility modes, V.18 universal transfer mode, etc. Verification of various implementations ensures these benefits are gained.

Slide9 l.jpg

Why V.18 Conformance testing is Important

  • Reduces complaints about textphones

    - Tighter control of textphone quality in the market ensures better reliability of textphone operation and reduces failure rate.

  • Benefits V.18 implementers

    - Allows verification of the implementation.
