UN Convention on the Rights of Persons with Disabilities
From Article 9, Accessibility:1. To enable persons with disabilities to live independently and participate fully in all aspects of life, States Parties shall take appropriate measures to ensure to persons with disabilities access, on an equal basis with others,... to information and communications... shall apply to, inter alia:... (b) Information, communications and other services, including electronic services and emergency services.

Total Conversation, the practical response to the UN requirement
Enables consistent voice, text and video communication at the same time and in real time.
Media:Audio for speech.Video for sign language, lip reading, and general showingReal-time text for good text contact for part or whole conversation
An open standardised concept, originally from ITU, now also in IETF, ETSI and 3GPP standards.
Defined in ITU-T F.703The base for conversational services for
all.Appreciated in implementations with
thousands of users.A small but important extension of the
videophone concept by adding real-time text.
Now supported to grow through the EU deployment project REACH112.
Real-time text: Text is sent at the same flow as it is typed. Near character-by-character. Gives good contact and efficient dialogue in intensive calls.

Call with media: Real-time text, video, voice.-desirable for all-essential for people with disabilities
-desirable for everyday calls-essential for emergency calls
Example: A deaf-blind woman in a Total Conversation call, producing sign-language and receiving text.

Deployment support through REACH112
European Commission funding for project ”Total Conversation and Emergency Services for all”.
In the Policy Support Program for deployment support.Fostered by the eInclusion unit in the ECStart July 2009. Run 3 Years.Pilot service provision in five countries with 22 partners.Different providers, different manufacturers, same protocolsA practical response on many years’ strong policy statements with goals to show sustainability and good use of Total Conversation:
for communication for all in everyday callsfor 112 emergency calls.Including use of relay services when needed

Good recent progress in standards
Total Conversation in the IP Multimedia Subsystem IMS.
3GPP TS 22.173 MMTEL3GPP TS 26.114 MMTEL media aspects
Relay Service standard defines use of Total Conversation for sign relay services.
ETSI ES 202 975 Harmonised Relay ServicesETSI TR 102 974 Relay Service Report
Emergency service standardIETF RFC 5012 Includes requirements for Total Conversation support to emergency services

Further standardisation needs
New conversational service environments need to include Total Conversation from the beginning.Call by destination number through relay services.
Described in Sweden 2006Implemented in USA 2009Implemented in REACH112 2009Need for agreed standard to simplify terminal manufacturing and interoperability.

Conclusion
REACH112 is an important step to deployment of Total Conversation.
In line with UN ConventionIn line with new EU directivesBenefit for all
Join the efforts to provide functional equivalence to telephony for all by providing interoperable Total Conversation!
