- Scope
- This standard specifies the transmit loudness rating (SLR), receive loudness rating (RLR), idle channel noise, transmit sensitivity/frequency characteristics, receive sensitivity/frequency characteristics, and sidetone masking evaluation values related to the audio performance of digital mobile terminals ( STMR), listener sidetone rating (LSTR), stability loss, acoustic echo control, transmit distortion, receive distortion, out-of-band signals, ambient noise suppression (ANR) and other technical requirements and test methods. This standard applies to various digital terminal equipment used to access public digital mobile networks, including 900/1800MHz TDMA digital cellular mobile communication network terminals, 900/1800MHz TDMA digital cellular mobile communication network General Packet Radio Service (GPRS) terminals, and 800MHz cdma2000 1x digital cellular mobile communication network terminal. 2GHz cdma2000 digital cellular mobile communication network terminal, 2GHz TC-SCDMA digital cellular mobile communication network terminal, 2GHz WCDMA digital cellular mobile communication network terminal. Other digital mobile terminals can also be used with reference.
