Enhanced telecommunication services architecture

A collection of slides from the author´s conference presentation is given. The Enhanced Telecommunication Services Architecture (or ETSA) is an architecture aimed at supporting any type of IN (Intelligent Network) or suplementary services on top of any transport network. This work is founded on ISDN (for the user to network interface plus the control of call and suplemenlxy services), IN (for the service composition mechanisms, call control and service feature definitions), GSM (for the mobility) and TINA (for the architectural framework). The ETSA provides a realistic approach to solve the problem of interoperability of services accross different network and service providers. Morover, it aims to give a solution for DN, based on object modeling and distributed computing. The work on ETSA started in the TINA-C Core-Team. Presently, this work is supported by Telefbnica in a VITNACTS project. The plans include an intial prototype by the end of 1.997, ancl a second version by 1.998.
