ETSI ETSI TR 102 775 V1.6.3 (2014-10) 71 Scope The present document provides guidance on the quality parameters that need to be considered at the Segment-connection of Voice over IP (VoIP) services and provides guidance on objectives for these

44、parameters. Inside the TISPAN NGN overall architecture (see figure 1), the present document considers only the transport layer.
