RTT communication (from clause 13.4.2 in TR 103 708)
Clause 6.2.1.1 introduces RTT, but does not define it. The reader needs to review the definition of Real-Time Text to find what it means. To reduce the risk that the requirement to support multiparty calling is missed, the following changes are proposed. The main clause to read:
Where ICT provides functionality that allows continuous real-time conversation, the ICT shall provide functionality that allows RTT communication, except where this would require design changes to add input or output hardware to the ICT.
The following note to be added:
NOTE 4: The definition of Real-Time Text implies support of multiparty RTT communication.
The results of these proposed changes can be previewed in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
