Scope

The present document aims at identifying and defining indicators and methodologies for a use in a context of end-user quality characterization and supervision of voice telephony services. In this context the measurements and metric determinations are perform by analysing signals accessible on user-end services and not on the network. In order to mirror the reality in terms of access to the services at the user-end measurements and analysis are perform on electrical signal that exclude the electro-acoustic part of the end equipment but the probe adaptation to electric interface of the end user equipment much take into account the electro-acoustic characteristics of this terminal.
