26、 The present document specifies the mapping of the AMR generic frame format (3GPP TS 26.101) to the Iu Interface (3GPP TS 25.415 7), the Uu Interface and the Nb Interface (3GPP TS 29.415). It further specifies the mapping of Enhanced Full Rate (GSM_EFR) coded speech and of PCM 64 kBit/s (ITU-T G.711

27、 9) coded speech to the Nb Interface in a BICC-based circuit switched core network. The present document also specifies the mapping of Full Rate (GSM_FR) coded speech and of Half Rate (GSM_HR) coded speech to the Nb Interface in a BICC-based circuit switched core network. The present document also s

28、pecifies the transport of the AMR Codec Types, the AMR-WB Codec Types, the GSM_EFR Codec, the GSM_FR Codec, the GSM_HR Codec and the ITU-T G.711 Codec over the A-Interface over IP (3GPP TS 48.002 11) and the Nb-Interface in a SIP-I -based circuit switched core network (3GPP TS 23.231 12). 2 Referenc
