Concurrent voice and text (from clause 13.4.3 in TR 103 708)
Clause 6.2.1.2 on "Concurrent voice and text" contains a Note 1 which is not very clearly expressed and will benefit from a rephrasing. A rewording of note 3 is proposed to make it easier to read. In note 4, it is proposed that the word "field" be deleted. In note 5, "sold" and "product" are proposed to be replaced by "provided" and "ICT system". The changed and added NOTES 1,3 and 5 of 6.2.1.2 are proposed to be worded as below while the other notes are proposed to be kept as-is except that all occurrences of "many-party" should be replaced by "multiparty":
NOTE 1: With multiparty communication, such as a conference system, conference floor control can be used to avoid confusion caused by multiple participants contributing at the same time.
NOTE 3: With a multiparty conference system that has chat as one of its features; RTT (like voice) would typically be separate from the chat so that RTT use does not interfere with chat. This separation allows participants to message in the chat field while a person contributes in real-time by RTT. This corresponds to the way participants message using chat while participants talk with voice. RTT users would then use RTT for presenting and use the chat feature to message while others are presenting by voice or RTT.
NOTE 5: Where both server-side software and local hardware and software are required to provide voice communication, where neither party can support voice communication without the other and are provided as a unit for the voice communication function, the local and server-side components are considered a single ICT system.
The results of these proposed changes can be previewed in Annex A of TR 103 708 ( tr_103708v010101p.pdf tr_103708v010101p.docx).
