Overview
SIST EN 300 822 V1.2.1:2003 is a Slovenian adoption of the European standard for the interworking of Digital Enhanced Cordless Telecommunications (DECT) and Integrated Services Digital Network (ISDN) systems, specifically focusing on the intermediate system configuration. The standard is vital for industries looking to implement seamless cordless access to ISDN services, ensuring compatibility, service transparency, and interoperability between equipment from various manufacturers.
This document is based on the ETSI EN 300 822 (V1.2.1), detailing the requirements, protocol architecture, and interworking profiles to enable ISDN terminals to access ISDN networks over DECT air interfaces. Both public and private ISDN infrastructures are included in its scope.
Key Topics
- DECT/ISDN Interworking: Specifies methods for providing ISDN services via a DECT wireless interface, allowing ISDN terminals cordless access to the network.
- Intermediate System Configuration: Defines the "Intermediate ISDN Access Profile (IIP)," where DECT Fixed Part (FP) and Portable Part (PP), both with Interworking Units (IWUs), serve as a gateway between the ISDN network and ISDN terminal.
- Service Transparency: Ensures that users have transparent access to a wide range of ISDN bearer services and supplementary functions, including speech, audio, unrestricted 64 kbit/s data, packet data, and user-signaling bearer services.
- Protocol Architecture: Describes the mapping and management of ISDN layer 3 messages to the DECT protocol stack, ensuring reliable communication and session management.
- Device Interoperability: Promotes multi-vendor equipment compatibility by formalizing the mapping of ISDN services over the DECT air interface.
Applications
The standard facilitates practical deployments where cordless communication and ISDN network integration are required, including:
- Enterprise Communication Systems: Enables offices to use portable, cordless ISDN terminals that maintain full ISDN service capabilities, promoting efficiency and mobility within organizations.
- Public Network Access: Supports public ISDN service providers in offering wireless access points through standardized DECT systems.
- Private Network Solutions: Ideal for in-house ISDN infrastructures, allowing seamless integration with existing DECT installations and reducing wiring complexity.
- Equipment Development: Manufacturers can use the standard as a baseline for developing interoperable DECT-ISDN gateways, terminals, and related infrastructure components.
- Migration and Upgrade Projects: Facilitates the upgrade of legacy ISDN networks to incorporate wireless access, preserving investment in ISDN while increasing flexibility with cordless solutions.
