Network Aspects (NA); Universal Personal Telecommunication (UPT); Phase 1 - Service description

Scope

This European Telecommunication Standard (ETS) provides general guidelines to present UPT Phase 1. The service description is related primarily to the service subscriber's and user's point of view, but does not deal with the details of human interface itself. This ETS includes information applicable to network operators, service providers and terminal, switch and database manufacturers. This ETS specifies the requirements where the service is provided to the user via a telecommunications network that is either the Pan-European Integrated Services Digital Network (ISDN) or a Public Switched Telephone Network (PSTN) as provided by European public telecommunications operators.
