Towards an Estelle specification of a European intelligent networks interface for universal personal communications and multimedia communications

摘要

In this paper, we present a protocol interface, called CSTA (computer supported telecommunications applications), that links the telecommunications and data processing environments to support a variety of applications. We specify it in Estelle, one of ISO's standard description techniques for communications protocols and distributed systems. CSTA allows flexible creation of new telecommunications services and applications. It allows computer users and applications to invoke telecommunications services on the switch. The CSTA protocol has applications in intelligent networks, customization of telecommunications services, multimedia communications, and universal personalized communications.
