The objective of this European Telecommunication Standard (ETS) 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 this ETS) consists of a bit-exact test where the reference is pre-computed and fixed.
