1 Scope
This standard specifies the technical requirements and testing methods for sending loudness rating (SLR), receiving loudness rating (RLR), idle channel noise, sending sensitivity/frequency characteristics, receiving sensitivity/frequency characteristics, side tone masking rating (STMR), acoustics echo control, sending distortion, receiving distortion, ambient noise rejection (ANR) and the like of digital mobile terminal.
It is applicable to all kinds of digital mobile terminal equipment used to connect with public digital mobile networks, including GSM (GPRS) terminal, WCDMA terminal, TD-SCDMA terminal, and cdma2000 terminal. It may be used as reference for other types of digital mobile terminals.
