9Non-voicetransmission(end-to-end) Abstract
Outlines transmission performance guidelines for voiceband services over networks that are an interconnection of an IP network (e.g. "the Internet") and the PSTN. This document is aimed at providing a set of principles on transmission performance aspects of hybrid Internet/PSTN connections to a wide audience.
