scope:
The objective of the present document is to define the conformance bounds for the TETRA speech and channel codec as deployed in the TETRA Speech Traffic Channel (TCH/S) channel type used in the TETRA Voice plus Data (V+D) equipment.
For the speech part of the TCH/S codec, the conformance testing (clause 7 of the present document) consists of a bit-exact test where the reference is pre-computed and fixed.
For the TCH/S channel encoding a bit exact conformance test is also defined (see clause 6.4).
For the TCH/S channel decoding, a non-bit exact test is employed with the specifications designed such that a sufficient quality of performance is met by the TETRA equipment (see clause 6.3).
