683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.1.4.1 Initial conditions | The DAI of the MS is connected to the SS and is set to the operating mode "Normal operation".
The SS sets up a speech call according to the generic call set up procedure.
The handset is mounted in the LRGP (see annex 1 of ITU-T Recommendation P.76) and the earpiece is sealed to the knife-edge of the artificial ear conf... |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.1.4.2 Procedure | An implementation of the ITU-T P.50 artificial speech is connected to the analogue or digital input of the reference speech encoder of the SS. This implementation is either a real time algorithm producing the artificial speech or a pre-recorded tape of artificial speech. Both "male" and "female" artificial speech is re... |

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.1 Definition | The receive-transmit stability margin is a measure of the gain that would have to be inserted between the go and return paths of the reference speech coder in the SS for oscillation to occur. |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.2 Conformance requirement | The stability margin shall be at least 6 dB.

683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.3 Test purpose | To verify that the stability margin is at least 6 dB. |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.4 Method of test | |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.4.1 Initial conditions | For handset operation the handset is placed on a hard plane surface with the transducers facing the surface.
For hands free operation the test setup is shown in ITU-T Recommendation P.34 (figure 3), but omitting the test table.
Where a user controlled volume control is provided it is set to maximum. |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.4.2 Procedure | a) A gain equivalent to the minimum stability margin is inserted in the loop between the go and return paths of the reference speech coder in the SS and any acoustic echo control is enabled.
b) A test signal according to ITU-T Recommendation O.131 is injected into the loop at the analogue or digital input of the refere... |
683b5b8a98f7b1390ddd5516ea9247a2 | 51.010-1 | 30.6.2.5 Test requirement | The minimum stability margin shall be 6 dB and no audible oscillation shall be detected. |
