Below are the questions. Your detailed answers will be highly appreciated. 1. Confirm the offered system meets the guaranteed maximum value of voice distortion and specify the offered solution's design distortion values. 2. Confirm the offered system has a guaranteed maximum value of loudness and specify the offered solution's design loudness criterion. 3. Confirm the maximum guaranteed jitter and explain how it compensates for, or minimize jitter in their system (including the design criteria for size of the jitter-buffers). 4. Confirm the maximum guaranteed packet loss-rate. Confirm this rate and the adopted strategy for compensating for, or minimising packet loss in the system. 5. Confirm that the system employs industry-standard or proprietary measures for packet recovery. 6. Confirm the offered system has a guaranteed maximum value of system-additive noise and specify the offered solution's design level of additive noise. 7. Confirm the offered system has a guaranteed maximum value of fade-distortion and specify the offered solution's design fade level. 8. Confirm the offered system has a guaranteed maximum value of cross-talk and shall specify the offered solution's design cross-talk limit. 9. Confirm the offered solution has a guaranteed, well-defined design voice quality score against an objective industry-standard clarity assessment system (such as ITU-T P.561/P.562). Either intrusive or non-intrusive measurement schemes shall be used and specify the test strategy including the test frequency-domain span. 10. Confirm the equipment achieves silence suppression and injects comfort noise into the circuit, without loss of the side-tone and specify the offered solution's design voice-suppression depth 11. Confirm the offered solution has a guaranteed maximum latency. The contributions to the latency shall be disclosed. 12. Confirm the offered solution has echo-canceller meeting or exceeding performance in ITU-G.165/G.168, and able to support ITU-T G.168-2002. An objective measure of PACE shall be specified. 13. Confirm the offered system compensates for front-end clipping and holdover suffered by a voice signal input. The implemented mitigation scheme shall be specified. 14. Confirm the offered solution has bandwidth gain. The techniques used to achieve the gain and the contribution from each technique shall be specified. 15. Confirm the offered solution's optimal environmental condition metrics. The optimal ambient metrics shall be disclosed (including but not limited to optimal temperature, altitude, air pressure, humidity, noise and shock resistance). 16. Confirm the offered system's electromagnetic power immunity from and emission into the environment and shall clearly state the compatibility certification for the proposed system.
