¿µ¹®³»¿ë¿ä¾à It is recognized that IP-based networks are increasingly used to deliver voice services to customers. These networks can impact the end-to-end service quality perceived by users. In order to maintain network performance required to deliver the desired service quality, several operational issues have to be considered. These issues include defining network performance measures and their objectives, Inter-Working issues between networks employing a variety of technologies, network measurement points, information to be exchanged between network operators, etc. This recommendation is for providing the general aspects of voice services in PSTN-IP-PSTN architecture, especially, for providing information whether or not the existing ITU-T recommendations could be applicable to PSTN-IP-PSTN voice architecture. Also, it covers the general impacts of IP networks to voice services and provides an overview of the performance measurement/management scope.
