7. ITU-T 7 14-16 July 2003 15th Biennial TDI International Conference – Las Vegas, Nevada, USA V.18 Conformance testing to the standard Why it is important

8. ITU-T 8 14-16 July 2003 15th Biennial TDI International Conference – Las Vegas, Nevada, USA 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.

9. ITU-T 9 14-16 July 2003 15th Biennial TDI International Conference – Las Vegas, Nevada, USA 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.

10. ITU-T 10 14-16 July 2003 15th Biennial TDI International Conference – Las Vegas, Nevada, USA V.18 conformance Tester Applications: Verification of proper implementation of V.18 according to the Appendix 4 of V.18 ITU-T Recommendation V.18 based Text Telephony Products
