Hi Antti, Roni, payload working group I did an update of the draft-ietf-tetra. Thanks a lot for your comments Antti - according your feedback we changed references from the historical ETSI TS 100 392-3-6 to ETSI TS 100 392-3-8. Indeed we did not change the control bit structure. As it is well defined in our draft-ietf-payload-tetra we do not need a bit equivalency to any ETSI standard. According Antti's comment regarding, it seems a bit superfluous to specify another slightly different format: There is one single specification (ETSI TS 100 392-3-8 ) addressing both circuit switched lines as well as for transport via RTP and it specifically addresses the application of a TETRA Intersystem Interface rather than a generic TETRA audio payload for RTP. Because of this fact the cited standard is little more TDM-stylish rather than pure RTP. There are attributes included as part of the payload which are either superfluous or at least confusing for pure RTP communications (e.g. call reference, traffic type which identifies codec, frame number – supposed to handle slipped frames in SDH). For this reasons we (the authors) of this draft think it is worth to specify a pure IP way to propagate TETRA payload via RTP and therefore ask IANA to register “audio/TETRA” as a valid payload type according the specification given here.

Juli 2019 21:05 To: i-d-announce@ietf.org Cc: payload@ietf.org Subject: [payload] I-D Action: draft-ietf-payload-tetra-03.txt A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Audio/Video Transport Payloads WG of the IETF. Title : RTP Payload Format for the TETRA Audio Codec Authors : Andreas Reisenbauer Udo Brandhuber Joachim Hagedorn Klaus-Peter Höhnsch Stefan Wenk Filename : draft-ietf-payload-tetra-03.txt Pages : 15 Date : 2019-07-26 Abstract: This document specifies a Real-time Transport Protocol (RTP) payload format for TETRA encoded speech signals. The payload format is designed to be able to interoperate with existing TETRA transport formats on non-IP networks. A media type registration is included, specifying the use of the RTP payload format and the storage format.
