ÖNORM EN 300395-4 V 1.3.1

Issue date: 2005 10 01

Terrestrial Trunked Radio (TETRA) - Speech codec for full-rate traffic channel - Part 4: Codec conformance testing (incl. CD-ROM!!!)

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).

Frequently Asked Questions about ÖNORM EN 300395-4 V 1.3.1

What is a "Single-User Licence"?

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.
