SSH ETS 300 395-3:1997 ed.1

Terrestrial Trunked Radio (TETRA); Speech codec for full-rate traffic channel; Part 3: Specific operating features

Scope

This European Telecommunication Standard (ETS) describes all the functions associated with the TETRA speech codec, excepted the specification of the codec by itself which is entirely defined in ETS 300 395-2 [2]. Clause 4 of this ETS provides a description of the functions associated with the speech encoder, while clause 5 is its counterpart for the speech decoder. Clause 6 describes the contents and the format of the signalling data block included in a stolen frame when used for transferring information relevant to the codec in a U-plane signalling message. In addition, annex A (informative) provides indications and preferred solutions for the implementation of optional features.
