Foreword

This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission

and Multiplexing (TM).

The present document contains the minimum technical requirements to ensure compatibility of products and

conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not

required to interwork at radio frequency (i.e. no common air interface). However, terminals may be combined with

other manufacturers' equipment on a Radio Frequency (RF) branching network for operation on different polarizations.

The present document defines the requirements of radio terminal and radio relay equipment and associated interfaces.

The requirements for multiplex, network management and antenna/feeder equipment may be addressed elsewhere.

The clauses containing essential requirements for Council Directive 89/336/EEC [30] (EMC Directive) are reported in

annex B.

The former title of the present document was: "Transmission and Multiplexing (TM); Digital Radio Relay Systems

(DRRS); High capacity DRRS carrying PDH and 1x Synchronous Transport Module-level 1 (1 x STM-1) signals

operatingin the 18GHz frequencybandwith channel spacing of55 MHz and27,5MHz".

1 Scope

The present document specifies parameters for high capacity STM-1 digital radio-relay systems designed to operate in

the 17,7 GHz to 19,7 GHz band. The channel spacing between adjacent co-polar channels shall be 55 MHz or

27,5 MHz. Operation in the Adjacent Channel Co-Polarization (ACCP) mode for class 4 systems and class 5 systems as

defined below with orthogonal polarizations or in the alternated cross-polar mode is foreseen. Additionally for class

4 systems, operation in the Co-Channel Dual Polarized (CCDP) mode with orthogonal polarization is also foreseen. The

present document covers both single and multi-channel systems.

The present document specifies the minimum performance parameters for terrestrial fixed service radio

communications equipment operating in the frequency range 17,7 GHz to 19,7 GHz and contains a revision from the

previous version, in the area of:

- categorization of previously considered equipments into a new spectrum efficiency class 4;

- introduction of unique system type codes for regulatory reference to the various system types detailed in the

present document, refer to new annex C and related categories of equipment classes of spectral efficiency;

- new spectrum efficiency class 5 for STM-1 capacity for 27,5 MHz Adjacent Channel Alternate-Polarization

(ACAP as class 5a) and Adjacent Channel Co-Polarization (ACCP as class 5b), see examples of the spectrum

usage in figures 1.1a and 1.1b:
Figure 1
- technical specifications relevant to the EMC Directive, detailed in annex B.

The applications of these digital radio-relay systems are anticipated to be in the regional and access networks, at data

rates of Synchronous Transport Module, level 1 (STM-1). The parameters to be specified fall into two categories:

a) those that are required to provide compatibility between channels from different sources of equipment on the

same route connected either to:
- separate antennas; or
- separate polarizations of the same antenna; or

- one polarization of one antenna at a frequency separation of 110 MHz or more, enabling, in addition for

class 4 equipment only, interworking of different manufacturers equipment at the same Radio Frequency

(RF) branching;

- this category also includes parameters providing compatibility with the existing radio-relay network.

b) parameters defining the transmission quality of the proposed system.

The standardization deals with RF and baseband characteristics. Antenna/feeder system requirements are covered in

EN 300 833 [33].

Two possible baseband interfaces for SDH systems have to be considered: one for STM-1 and another for 140 Mbit/s

signals.

The present document does not contain aspects related to test procedures and test conditions, however they are to be

found in EN 301 126-1 [19].

As the maximum transmission rate in a given bandwidth depends on systems spectral efficiency, different classes are

defined:

- class 4: equipment spectral efficiency based on typically 16 or 32-states modulation scheme (e.g. 16-QAM,

32-QAM, or equivalent);

- class 5: equipment spectral efficiency based on typically 64 or 128-states modulation scheme (e.g. 64-QAM,

128-QAM, or equivalent).

The above classes are indicative only and do not imply any constraint to the actual modulation format, provided that all

the requirements in the present document are met.

Safety aspects will not be considered in the present document. However compliance to EN 60950 [28] will be required

to comply with Directive 1999/5/EC [29] (R&TTE).

Technical background for most of the parameters and requirements referred in the present document may be found in

TR 101 036-1 [20].
