Scope

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. For the TCH/S channel encoding a bit exact conformance test is also defined (see subclause 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 subclause 6.3).
