Overview

SIST EN 301 128 V1.1.1:2003 sets out essential guidelines for the implementation of digital radio relay systems (DRRS) in the 13 GHz, 15 GHz, and 18 GHz frequency bands, focusing specifically on plesiochronous digital hierarchy (PDH) systems with low and medium capacity requirements. Developed by SIT and aligned with ETSI standards, this standard replaces obsolete documentation to reflect current radio networking capacities, particularly in applications where lower bitrates than 34 Mbit/s are needed. By standardizing transmission and multiplexing in fixed radio relay and satellite communication systems, SIST EN 301 128 promotes interoperability, efficiency, and reliability for network operators in Slovenia and across Europe.

Key Topics

• Frequency Bands Covered: Focuses on DRRS operating in the 13 GHz, 15 GHz, and 18 GHz bands, essential for operators deploying microwave radio links.
• Capacity Requirements: Addresses the need for low and medium capacity digital radio relay systems, enabling efficient network design for areas with modest traffic demands.
• Plesiochronous Digital Hierarchy (PDH): Establishes technical requirements for PDH, supporting robust and standardized data transport over radio links.
• Transmission and Multiplexing: Sets guidelines on how data should be transmitted and multiplexed through radio relay systems, ensuring reliable and interference-resistant operation.
• Replacement of Outdated Standards: Supersedes T/TR 04-42, integrating new capacity requirements and technical advancements in DRRS.

Applications

This standard is critical for industries and operators that deploy microwave digital radio relay systems for regional, urban, or last-mile telecommunications infrastructures. Key applications include:

• Telecommunications: Ensures reliable backhaul and backbone connections for voice, data, and broadband services, particularly where fiber deployment is impractical.
• Enterprise Networks: Supports private radio networks for utilities, transportation systems, and large enterprises needing secure, efficient communications.
• Satellite Communications: Facilitates interface compatibility with fixed satellite services, improving system integration and management.
• Network Expansion and Modernization: Guides network operators in refreshing legacy systems or expanding services to underserved regions using standardized equipment and protocols.
• Public Safety and Mission-Critical Networks: Provides a foundation for secure and dependable communication channels necessary for emergency services.

Related Standards

For comprehensive compliance and optimal system integration, the following related standards should be considered:

• EN 301 128 Series: Covers additional aspects of digital radio relay systems, including different frequency bands or system capacities.
• ETSI Standards: Provide broader guidelines on transmission and multiplexing, electromagnetic compatibility (EMC), and safety for telecommunications networks.
• ITU-T Recommendations (G.703, G.704, G.823, etc.): Define PDH frame structures, synchronization, and performance requirements for digital transmission systems.
• IEC 60835 Series: Pertains to fixed radio systems used in line-of-sight radio relay applications, covering relevant system and test requirements.
