Mobile Total Conversation
Interworking with the existing and emerging
forms of text conversation is the key to success
Standardisation, needed
for successful service
establishment
Co-operate in creating standards for interworking
Compete with the smartest implementation of the
standards
Society support
In resolution on Sign Language B4-0985/98, the
European Parliament ”Calls on the commission to
introduce a proposal for framework legislation to
ensure compatibility of telecommunications text
and videophone equipment for deaf people across
Europe.”
Total Conversation can be the technical response
on that request.
Proposals
Support for
Pilot implementations and trials
 Further standardisation as needs arise
 Relay service establishment
 Knowledge dissemination for future
interworking
 Procurements requiring the standards
