ITU-T V. 18 Practical aspects of the standard and general misconceptions about it 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 3
Why V. 18 ? ITU-T ØInternational standard - Accepted as a standard in all European countries, Australia & New Zealand ØBridge between old and new technologies - Higher speed modems - Multimedia ØInter-working - Can inter-work with any existing text Telephone - Future global integration with Internet & Multimedia ØEase of use - More reliable call set-up - User friendly operation 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 4
V. 18 Modes ITU-T Compatibility Mode V. 18 Mode Used with existing Textphones Used between two V. 18 Textphones - V. 21 (Sweden, UK) - Baudot (45 and 50 bps) (USA, UK, Ireland) - EDT (Italy, Germany) - Bell 103 (USA) - V. 23 (France) - DTMF (Denmark, Sweden, Netherlands) 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 5
Current development of V. 18 ITU-T • CTM Mobile access for the textphones • Simultaneous Text & Voice 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 6
ITU-T V. 18 Conformance testing to the standard Why it is important 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 7
Why V. 18 Conformance testing is Important ITU-T Ø Specified in V. 18 Recommendation Appendix 4 Ø 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. Ø 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. 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 8
Why V. 18 Conformance testing is Important ITU-T ØReduces complaints about textphones - Tighter control of textphone quality in the market ensures better reliability of textphone operation and reduces failure rate. ØBenefits V. 18 implementers - Allows verification of the implementation. 14 -16 July 2003 15 th Biennial TDI International Conference – Las Vegas, Nevada, USA 9
