Overview
SIST ETS 300 438-1:1997 is a European telecommunications standard detailing the Service Specific Co-ordination Function (SSCF) for support of signalling at the Network Node Interface (NNI) within the Broadband Integrated Services Digital Network (B-ISDN). This document specifies how the Signalling ATM Adaptation Layer (SAAL) supports efficient and reliable network signalling at the NNI, based on ITU-T Recommendation Q.2140 (1995) with specific modifications for European requirements. The standard is targeted at network equipment manufacturers and operators aiming to implement or maintain B-ISDN infrastructures, promoting interoperability and alignment with both ITU-T and European standards.
Key Topics
- Service Specific Co-ordination Function (SSCF): Core set of rules and functions within the SAAL that enable coordinated, robust signalling support at the NNI.
- Signalling ATM Adaptation Layer (SAAL): Describes adaptation mechanisms ensuring seamless transfer of signalling messages over Asynchronous Transfer Mode (ATM) networks.
- Network Node Interface (NNI) Requirements: Outlines how SSCF enables proper signalling between network elements at the interface points within the B-ISDN architecture.
- Mapping to Layer 3 Protocols: SSCF translates and adapts the services of the Service Specific Connection Oriented Protocol (SSCOP) to suit higher-level protocols required for NNI signalling.
- Relationship to Related Protocols: Relates to protocol entities defined in other standards, particularly ETS 300 008 (ISDN, Signalling System No.7, MTP) and ETS 300 436-1 (SAAL, SSCOP).
Applications
SIST ETS 300 438-1:1997 is practically applied in several key areas within the broadband communications domain:
- B-ISDN Infrastructure: Supporting the core signalling functions necessary to establish, manage, and terminate connections across large-scale integrated services digital networks.
- Telecommunications Equipment: Used by manufacturers to develop compatible network node interfaces in ATM-based networks, ensuring consistency across devices from different vendors.
- Interoperability Testing: Facilitates rigorous conformance and interoperability testing by defining signalling adaptation requirements and references for conformance (see related standards for PICS proforma).
- Modernization and Maintenance: Essential for operators transitioning legacy networks to ATM-based B-ISDN or integrating new equipment into existing infrastructure.
- Network Reliability and Performance: Enhances network reliability by specifying adaptations and timer parameters critical for performance under varying network conditions.
Related Standards
- ETSI ETS 300 008: Integrated Services Digital Network (ISDN); Signalling System No.7; Message Transfer Part (MTP) specification.
- ETSI ETS 300 436-1: B-ISDN; SAAL; Service Specific Connection Oriented Protocol (SSCOP), protocol specification based on ITU-T Q.2110.
- ITU-T Recommendation Q.2140: Baseline version of the SSCF at NNI, with the SIST/ETSI modifications providing European-specific adaptations.
- ETSI ETS 300 438-2: Companion document detailing protocol implementation conformance statements (PICS) for SSCF at NNI.
- ITU-T Recommendation Q.2100: Defines the architecture for the ATM Adaptation Layer relevant to B-ISDN.
Adherence to SIST ETS 300 438-1:1997 ensures the reliable implementation and operation of signalling functions in B-ISDN networks, supporting industry goals of network interoperability, scalability, and future-proof deployment in broadband telecommunication environments.
