Overview
SIST EN 301 920 V1.1.1:2005 specifies the requirements for the Simple Dialog supplementary service within a Private Integrated Services Network (PISN). Developed by the Slovenski inštitut za standardizacijo (SIST) and endorsed by ETSI, this standard modifies and aligns with ISO/IEC 21407 (2001). The Simple Dialog service facilitates transparent communication of keypad and display information between users or between a user and an application over a PISN, enhancing efficiency in telecommunication networks that implement ISDN-based solutions.
Key Topics
-
Simple Dialog Service
This supplementary service enables the transparent exchange of messages, such as keypad entries and display prompts, between devices and users within a PISN.
-
Functional Model
Defines how the Simple Dialog service is structured within the broader network, including interactions between endpoints and applications.
-
Information Flows
Specifies the signaling and protocol details necessary for reliable message exchange between network elements supporting this service.
-
Integration with ISDN Concepts
Adopts and modifies ISDN and OSI architectural principles for compatibility and seamless integration into existing telecommunications infrastructure.
-
Alignment with International Standards
SIST EN 301 920 V1.1.1:2005 is based on ISO/IEC 21407 and aligns with other relevant standards to ensure interoperability across multiple networks and vendors.
Applications
The Simple Dialog supplementary service defined in this standard offers significant practical value for private and enterprise communication environments:
-
Enhanced User-Application Interaction
Allows users to interact with telephony applications (e.g., voicemail, call routing systems) using standardized keypad and display functions.
-
Custom Business Communication Solutions
Supports development of custom enterprise solutions for call handling, employee communication, and customer service via secure and reliable information exchange.
-
Seamless Integration in Hybrid Environments
Facilitates integration of modern services with legacy telephony systems by adhering to international ISDN protocols and PISN architecture.
-
Telecommunications Network Efficiency
Streamlines network signaling and reduces errors by providing a structured model for supplementary services, resulting in more reliable communication flows.
-
End-user Benefits
Delivers straightforward and intuitive service interfaces for end-users, improving the overall telecommunication experience within private networks.
