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

General Comment:

Detailed Review Comments:

2.
TETRA: TErrestial Trunked RAdio
(>>have a look at the capitals)

3.
The TETRA codec is designed in such a way that on the air
   interface two of these 30ms samples are transported together (sub-
   block 1 and sub-block 2).
(>> "these" instead of "theses")

Codec payload is specified for TDM lines with 2048 kBit/s serialisation within the
   traditional circuit mode based TETRA system
(>>place "traditional circuit mode based TETRA system" at the end)

These two formats  differ mainly ...
(>> usage of "differ" instead of "defer")

5.
Note: This example shows the usage of OSTE mapping.
(>>usage of "the" instead of "of")

Kind Regards
