• Impairment from random packet loss was added to G.107 in the 2002 edition, parameterised per codec. in context
• The 2005 edition of G.107 improved quality prediction for codecs under short-term dependent (bursty) packet loss. in context
• G.107 (06/15) adds delay-sensitivity parameters: carrier-grade or enterprise-grade telephony must use the defaults, while systems with low or very low interactivity requirements may use different values. in context
• The E-model is built on transmission impairment factors intended to reflect the effects of modern signal processing devices. in context
• ITU-T positions the G.107 E-model as a transmission rating model for transmission planners, whose primary output is a scalar rating of transmission quality. in context
• G.107 (06/15) includes a reference implementation of the E-model in Appendix III. in context
• G.107 carried a provisional wideband impairment framework in a 2009 Appendix II, which was replaced in 2011 by the separate Recommendation ITU-T G.107.1. in context
• An R value from the narrowband G.107 model should not be applied unchanged to wideband codec calls, because ITU-T handles wideband in a separate Recommendation (G.107.1). inferred in context
