ITU-T G.795 SPANISH-1988 CHARACTERISTICS OF CODECS FOR FDM ASSEMBLIES - GENERAL ASPECTS OF DIGITAL TRANSMISSION SYSTEMS - TERMINAL EQUIPMENTS Study Groups XV and XVIII
This Recommendation gives details of the analogue interfaces, the overall analogue-to-analogue performance of a coder/decoder pair and certain details of the digital interfaces to which FDM codecs should conform. The CCITT does not recommend any particular relationship between FDM assemblies and the digital hierarchies to be used in any codec realization nor does it recommend any particular frame structure or encoding law. Administrations intending to use codecs in their networks should ensure that compatible designs of codec are used at each end of a link. For international links, the codecs to be used should be by the agreement of the Administrations concerned. An Annex to this Recommendation gives details supplied by some Administrations of a number of FDM codec realizations.
