This European Telecommunication Standard (ETS) specifies the digital test sequences for the GSM enhanced full rate speech codec. These sequences test for a bit exact implementation of the enhanced full rate speech transcoder (GSM 06.60 (ETS 300 726) [2])@ Voice Activity Detection (GSM 06.82 (ETS 300 730) [6])@ comfort noise (GSM 06.62 (ETS 300 728) [4]) and the discontinuous transmission (GSM 06.81 (ETS 300 729) [5]).
