SIST EN 300 430 V1.2.1:2003 is the Slovenian adoption of ETSI EN 300 430 V1.2.1, an ETSI European Standard for fixed point-to-point radio systems. It specifies minimum technical parameters for STM-1 digital radio-relay equipment operating in the 17.7 GHz to 19.7 GHz band, with 55 MHz and 27.5 MHz channel spacing, for manufacturers, operators, regulators and conformance testers.

What does SIST EN 300 430 V1.2.1:2003 specify?

SIST EN 300 430 V1.2.1:2003 specifies the RF and baseband characteristics needed for high-capacity STM-1 digital radio-relay systems in the 18 GHz range. It is written for compatibility between systems on the same route, for radio planning, and for licensing and conformance use.

The document is organized into scope, references, symbols and abbreviations, general characteristics, system parameters, three annexes, bibliography and history. The main body covers channel arrangements, environmental and power-supply conditions, transmitter and receiver limits, and system performance. The annexes add channel-arrangement background, EMC cross-references and licensing type codes.

Annex	What it covers
Annex A	Additional information such as channel arrangement, feeder/antenna return loss, ATPC, spectrum masks, RBER, and co-channel or adjacent-channel interference
Annex B	Essential requirements for the EC Council Directive 89/336 (EMCDirective)
Annex C	System type codes for regulatory procedures and national licensing

What are the key requirements of SIST EN 300 430 V1.2.1:2003?

Radio band, channel plans and system classes

Clause 4.1 requires operation in the 17.7 GHz to 19.7 GHz band with 55 MHz or 27.5 MHz channel spacing, using the channel plans in CEPT Recommendation 12-03 or ITU-R Recommendation F.595-6. The standard also distinguishes class 4 and class 5 systems by spectral efficiency, which matters because the class determines the applicable spectrum mask and compatibility conditions.

Clause 4.2 sets the compatibility cases for equipment sharing a route or antenna. In practice, this tells the designer whether the equipment must work with separate antennas, shared polarization, or different manufacturers on the same branching network.

Performance, environment, power and EMC

Clause 4.3 requires systems to meet ITU-R high-grade performance and availability objectives, supported by ITU-T error-performance objectives. Clause 4.4 ties the equipment to ETS 300 019 environmental classes, and the manufacturer must declare the intended class. Clause 4.5 links the power supply interface to ETS 300 132-1 and ETS 300 132-2, and clause 4.6 requires operation under EN 300 385 EMC conditions.

For a buyer or integrator, these clauses show the installation environment, supply arrangement and electromagnetic behavior that the equipment is expected to survive and pass.

Baseband, transmitter and receiver behavior

Clause 5.2 covers the baseband interfaces. SIST EN 300 430 V1.2.1:2003 addresses 140 Mbit/s plesiochronous interfaces and STM-1 SDH interfaces, including electrical CMI and optical STM-1 options. Clause 5.3 then defines transmitter behavior such as power range, optional ATPC, RTPC and RFC, output-power tolerance, RF spectrum mask, spurious emissions and radiofrequency tolerance. Clause 5.4 covers receiver input range, image rejection and internal and external spurious emissions.

In practice, these clauses define what the radio must accept, radiate and keep within limits during operation and testing.

Link performance and interference

Clause 5.5 gives the main link-performance measures without diversity: BER versus receive signal level, Residual BER (RBER), co-channel and adjacent-channel interference sensitivity, CW spurious interference and distortion sensitivity. Clause 5.6 states that spacediversity receive is not relevant for the systems covered here. For network planning, this is the part that helps determine whether the link will hold the required error performance in realistic radio conditions.

What terms does SIST EN 300 430 V1.2.1:2003 define?

• STM-1 (Synchronous Transport Module, level 1) - the SDH payload rate used by the equipment.
• ATPC (Automatic Transmit Power Control) - an optional feature that changes transmit power within declared limits.
• RTPC (Remote Transmit Power Control) - remote control of transmit power, also optional.
• RFC (Remote Frequency Control) - remote control of the operating frequency or channel setting.
• XPD (cross-Polar Discrimination) - a measure of isolation between polarizations on an antenna.
• IPI (Inter-Port Isolation) - isolation between antenna ports.
• RSL (Receive Signal Level) - the received level used in BER and sensitivity assessments.
• RBER (Residual BER) - the residual error rate measured under simulated operating conditions, including interference cases.

Who uses SIST EN 300 430 V1.2.1:2003?

This standard is used by radio system manufacturers, RF and transmission engineers, network planners, test laboratories, regulators and procurement teams. They use it to choose channel arrangements, define equipment classes, set environmental and power-supply expectations, and verify spectrum, BER and interference performance for fixed radio links in regional and access networks.

Which standards are used with SIST EN 300 430 V1.2.1:2003?

• CEPT Recommendation 12-03 and ITU-R Recommendation F.595-6 - channel arrangements in the 17.7 GHz to 19.7 GHz band.
• ITU-R Recommendations F.634-4 and F.695 - high-grade error performance and availability objectives.
• ETS 300 019-1 and ETS 300 019-2 - environmental classes and environmental tests.
• ETS 300 132-1 and ETS 300 132-2 - power-supply interfaces.
• ITU-T Recommendations G.703, G.784 and G.957 - PDH, SDH and STM-1 interface characteristics and management aspects.
• ITU-R Recommendations F.750-3 and F.751-2 - SDH radio-relay architecture and transmission characteristics.
• EN 300 385 and EN 301 489-4 - EMC conditions and EMC requirements for fixed radio links.
• EN 301 126-1 - conformance testing framework for point-to-point equipment.
• EN 300 833 - antenna radiation patterns, XPD, IPI and return loss.
• CEPT/ERC Recommendation 74-01 - spurious emissions.
• EN 300 645 and ETS 300 635 - TMN information model and SDH radio-specific functional blocks.

What does the SIST EN 300 430 V1.2.1:2003 document contain?

The document contains a system block diagram, channel-arrangement guidance, spectrum-mask figures, BER and RBER performance limits, interference-sensitivity criteria and receiver image-rejection requirements. It also includes tables for channel spacing, spectrum-analyser settings, internal spurious emissions, performance thresholds and system type codes.

Annex A gives practical background for planning and testing, including return loss and ATPC use. Annex B links specific clauses to the EMC Directive, and Annex C assigns system type codes for national licensing and regulatory procedures.
