SIST-TS TS 102 024-4 V4.1.1:2004 is the Slovenian identical version of ETSI TS 102 024-4 V4.1.1, a Technical Specification for TIPHON Release 4 end-to-end Quality of Service (QoS) management. It specifies high-level procedures for monitoring end-to-end QoS performance within and between TIPHON domains in a multi-media environment, including secure monitoring of firewall devices. It is aimed at people who design, operate, maintain, and verify TIPHON networks and services.

What does SIST-TS TS 102 024-4 V4.1.1:2004 specify?

SIST-TS TS 102 024-4 V4.1.1:2004 specifies the high-level requirements for managing TIPHON end-to-end QoS. The document is based on the TIPHON network management framework in TS 101 303, and it focuses on the management tasks needed to keep speech and service quality under control.

The scope ties these procedures to annex material for TIPHON meta-protocols, object definitions, and profile mappings from candidate protocols to TIPHON meta-protocols. In practice, that means the document is not only about monitoring results, but also about the information model and protocol mapping needed to exchange QoS management data.

What are the key requirements of SIST-TS TS 102 024-4 V4.1.1:2004?

SIST-TS TS 102 024-4 V4.1.1:2004 treats QoS management as a lifecycle activity: planning and configuration, maintenance, and monitoring and verification. In practice, operators need procedures that cover design, operation, fault diagnosis, and ongoing checks, not just one-time network setup.

Transmission planning

Clause 4 says transmission planning should be done during the design phase of TIPHON equipment and networks. The document also says design should not stop at the minimum limits of a QoS class. For the reader, this means the network has to be engineered with margin, because borderline design can still fail in real use.

For critical end-to-end connections, any change in transmission parameters should be judged using E-model calculations. The document also warns about devices such as Automatic Level Control (ALC) that vary transmission parameters dynamically. In practice, this means changes that look harmless on paper still need speech-quality analysis.

Maintenance and diagnosis

Clause 4 requires keeping track of parameter changes, including changes to Send and Receive Loudness Rating, whether they happen automatically or by user action. The document also points to tools such as reset-to-default functions and log files. This matters because user complaints about poor speech quality often require a trace of what changed.

Monitoring and verification

SIST-TS TS 102 024-4 V4.1.1:2004 says a TIPHON system should be monitored continuously once it is in service. Verification needs access to the actual settings of major transmission parameters, including those the user can change. In practice, operators must compare intended settings with real settings, not just rely on configuration records.

Capacity planning and service agreements

Clause 5 says guaranteed QoS depends on capacity planning that matches predicted traffic load. Where networks cooperate, Service Level Agreements (SLAs) should define traffic volume, QoS level, price, treatment of excess traffic, and compensation when QoS is not met. For buyers and service providers, this means technical capacity and commercial commitments have to match.

Routing table management

The document says routing tables should be set to make best use of available capacity within each domain. Routing decisions can depend on destination, originating network or customer, requested QoS, time of day, cost, and whether traffic is inside or outside the capacity agreement. It also calls for access control to prevent unauthorized traffic from degrading existing calls.

The routing model from EN 300 292 is extended with a requested QoS attribute, and the QoSDescriptor data type includes transport parameters and QoS classes. In practice, routing needs to be QoS-aware, not only destination-aware.

Traffic management and performance monitoring

SIST-TS TS 102 024-4 V4.1.1:2004 requires real-time or near real-time traffic management to preserve QoS. It calls for congestion alarms and for routing to be adjusted when congestion or equipment failures are reported. It also requires performance monitoring of packet loss and packet delay, both per call and over a known period. That gives operators the figures they need for customer reporting and SLA follow-up.

What terms does SIST-TS TS 102 024-4 V4.1.1:2004 define?

Quality of Service (QoS) - The performance level that TIPHON aims to manage end to end across the network and service path.

Automatic Level Control (ALC) - A device or function that changes levels automatically, which can affect speech transmission quality.

Service Level Agreement (SLA) - The agreement that sets traffic, QoS, pricing, excess-traffic handling, and compensation terms between parties.

Switched Circuit Networks (SCN) - Circuit-switched networks used in the document as a contrast to IP-based “best effort” networking.

Internet Protocol (IP) - The packet-based transport technology that TIPHON uses alongside SCN in end-to-end calls.

Who uses SIST-TS TS 102 024-4 V4.1.1:2004?

SIST-TS TS 102 024-4 V4.1.1:2004 is used by TIPHON service providers, network operators, and engineers who plan and operate IP and telephony services. It is also relevant to equipment designers, people responsible for maintenance and troubleshooting, and teams that manage routing, traffic, and QoS reporting. Buyers and quality managers can use it to check whether a proposed TIPHON solution supports the monitoring and control processes they need.

Which standards are used with SIST-TS TS 102 024-4 V4.1.1:2004?

Standard	What it contributes
ETSI TS 101 303	The general TIPHON service and network management framework on which this document is based.
ETSI EN 300 292	The routing management model that TIPHON extends with requested QoS.
ITU-T Recommendation E.416	Broader network management principles and functions for B-ISDN traffic.
ITU-T Recommendation E.417	The framework for network management of IP-based networks.
ITU-T Recommendation G.107	The E-model used for transmission planning judgments.

The TIPHON family named in the foreword also includes TS 102 024-1, -2, -3, -5, -6, -7, -9, and -10, covering general QoS aspects, speech QoS classes, signalling and control, measurement methodologies, network and terminal characteristics, design guidance, call performance classification, and terminal requirements.

What does the SIST-TS TS 102 024-4 V4.1.1:2004 document contain?

The document includes assumptions for guaranteed end-to-end speech quality, then develops the management requirements that support that goal. Clause 4 covers transmission planning, maintenance, and monitoring and verification, while Clause 5 covers capacity planning, routing table management, traffic management, and performance monitoring.

It also includes two UML figures: one for extending the EN 300 292 routing model with requested QoS, and one for QoS performance management information such as packet loss and packet delay. Annex A provides the bibliography used by the document.
