SIST EN 300 636 V1.2.1:2003 is the Slovenian adoption of the ETSI European standard for fixed radio systems using point-to-multipoint (P-MP) Time Division Multiple Access (TDMA) digital links in the 1 GHz to 3 GHz range. It specifies radio, interface, power, environmental and electromagnetic compatibility requirements for equipment that connects subscribers to public or private networks.

What does SIST EN 300 636 V1.2.1:2003 specify?

SIST EN 300 636 V1.2.1:2003 covers P-MP applications for voice, telex, low speed data up to 64 kbit/s, and Integrated Services Digital Network (ISDN) basic rate access. It applies to fixed services in the 1.5 GHz, 2.2 GHz, 2.4 GHz and 2.6 GHz bands, and it is organized around scope, references, symbols, system architecture, radio characteristics, service interfaces, and power supply/environmental characteristics.

The document’s main technical structure is:

• Clause 4 - general system architecture
• Clause 5 - radio characteristics
• Clause 6 - types of services and subscriber/exchange interfaces
• Clause 7 - power supply and environmental characteristics

What are the key requirements of SIST EN 300 636 V1.2.1:2003?

SIST EN 300 636 V1.2.1:2003 sets the performance and interface profile for a TDMA P-MP fixed radio system. In practice, it tells a designer or buyer what traffic capacity, RF behavior, interfaces and deployment conditions the equipment must support.

System performance and timing

• The system traffic carrying capacity shall be n x 2 Mbit/s, with n equal to 1, 2 or 4. This means the basic system sizes are 2, 4 and 8 Mbit/s.
• Transmission error performance shall comply with ITU-T Recommendation G.821. This gives the operator a familiar benchmark for end-to-end digital quality.
• Roundtrip delay, including transmission delay, shall not exceed 20 ms for a voice encoded 64 kbit/s timeslot. This matters for speech quality and user experience.
• The system shall be fully transparent, so the exchange and the subscriber communicate without being aware of the radio link.

Radio frequency requirements

• Five frequency plans are used across the specified bands, with channel arrangements tied to the band and bitrate.
• The maximum output power at point C shall not exceed 35 dBm, and a means of adjustment shall be provided where lower power is needed. This supports both regulatory compliance and network planning.
• The transmitted spectrum is checked with a full-load PRBS signal and a defined spectrum mask. That is the basis for checking adjacent-channel behavior in testing.
• Transmitter spurious emissions are controlled by CEPT/ERC Recommendation 74-01 outside the range linked to the relevant channel separation.
• Receiver performance includes a minimum dynamic range of 55 dB above the BER = 10^-3 threshold, BER performance limits by bitrate, adjacent-channel and co-channel rejection, and image frequency rejection greater than 75 dB where applicable.

Interfaces, power and installation conditions

• At least one service or network interface from the listed set shall be implemented, including analogue 2-wire, analogue 4W + E&M, telex, digital data port, ISDN basic rate, 2 Mbit/s, and V5.1/V5.2.
• The equipment shall support internal and external synchronization, with the free-running clock within 50 ppm of nominal and the incoming timing signal also within 50 ppm.
• Power supply shall comply with the stated DC and AC ranges and with ETS 300 132.
• Environmental operation follows ETS 300 019 classes for weather protected and non-weather protected locations.
• EMC operation shall meet EN 300 385, and feeder/antenna parameters shall follow EN 300 631.

What terms does SIST EN 300 636 V1.2.1:2003 define?

• Point-to-Multipoint (P-MP) - A radio system that connects one central station to multiple remote stations.
• Time Division Multiple Access (TDMA) - An access method where users share radio capacity in time slots.
• Demand Assigned Multiple Access (DAMA) - A system where channels are allocated when calls are established and released when they end.
• Bit Error Rate (BER) - The rate used to judge digital reception quality.
• Telecommunications Management Network (TMN) - The management interface used for supervising transmission systems.
• Pseudo-Random Binary Sequence (PRBS) - A test pattern used to measure transmitter and receiver behavior under load.

Who uses SIST EN 300 636 V1.2.1:2003?

SIST EN 300 636 V1.2.1:2003 is used by manufacturers, network operators, test laboratories, and procurement or quality teams working with fixed radio access equipment. It is relevant for designing central stations, terminal stations and repeater stations, selecting supported interfaces, and verifying RF, BER, power supply, EMC and environmental performance.

What changed in SIST EN 300 636 V1.2.1:2003 from the previous edition?

SIST EN 300 636 V1.2.1:2003 is a revision of ETS 300 636. The foreword states that clause 2, subclauses 5.3.3, 5.4.2 and 7.3 were modified and approved as amendment ETS 300 636/A1. The former title was “Transmission and Multiplexing (TM); Time Division Multiple Access (TDMA) point-to-multipoint digital radio systems in the frequency range 1 to 3 GHz”.

Which standards are used with SIST EN 300 636 V1.2.1:2003?

• CEPT Recommendation T/R 13-01 and ITU-R Recommendation F.701-2 - channel arrangements for the 1.5 GHz, 2.2 GHz, 2.4 GHz and 2.6 GHz bands.
• ITU-T Recommendation G.821 and G.773 - digital error performance and TMN Q-interface protocols.
• ITU-T Recommendation G.712, ITU-T Recommendation G.703, CCITT Recommendation R.20, ETS 300 012, ETS 300 324, and EN 300 347 - analogue, digital, telex, ISDN, and V5.x interface definitions.
• ETS 300 132 and ETS 300 019 - power supply interface and environmental classes and tests.
• EN 300 385, EN 300 631, and CEPT/ERC Recommendation 74-01 - EMC, antenna parameters, and spurious emission limits.

What does the SIST EN 300 636 V1.2.1:2003 document contain?

SIST EN 300 636 V1.2.1:2003 contains a general system architecture figure and an RF block diagram, plus tables for frequency bands, channel spacing, BER versus receive signal level, interface types, and power supply ranges. It also gives test-oriented descriptions for transmitter power, spectrum mask, spurious emissions, receiver rejection, return loss, synchronization, and environmental applicability. These parts are used for design review, bench testing, conformance assessment, and equipment selection.
