Re: [payload] Comment on RTP Payload Format for the TETRA Audio Codec

[Juergen Machui <[e-mail]>]

Hallo Roni,

yes I can confirm that.

Any Tetra interface definition must describe the way the voice payload is transported.
Of course ideally Tetra manufacturers should standardize the complete interface description to control centers.
But having this part well defined offers an excellent first step and significantly helps to reduce the variety.

Freundliche Grüße

Jurgen thanks,
Can you also verify that section 4 and 5 of the draft defining the  payload format and payload header cover your use case
Thanks

Subject: [payload] Comment on RTP Payload Format for the TETRA Audio Codec

Dear sir,

please allow me to comment on the
Internet-Draft RTP Payload Format for TETRA Audio codec April 2018.

The international community strives to establish standards for the interfacing of radio systems an control centers.
This need is growing as control centers do typically communicate via more than one radio media.
In this context we encounter Tetra systems in most control center projects,
unfortunately using different interface definitions for both speech transport and signaling purposes.

This fact represents an enormous cost factor to manufacturers and users of control center technology.
Tetra interfaces move to pure IP definitions and there is a real danger that the variety if interface definitions will grow further.
A well established standard for voice transport can help to reduce the impact of this trend.

The present draft seems to me a practical way to handle this issue.
I strongly recommend to adopt it.

Best regards

Jürgen Machui
