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 the European states of interest to ETSI Member. Radio terminals from
different manufacturers are not required to interwork at radio frequency (i.e. no common air interface).
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 present document is a revision of ETS 300 639. Clause 2, subclauses 6.5, 6.5.1 and 6.5.2 have been modified and
approved as amendment under ETS 300 639/A1, under ETSI Standards One-step Approval Procedure 9956. The
complete document is published as EN 300 639 V1.2.1.
The former title of the present document was: "Transmission and Multiplexing (TM); Sub-STM1 Digital Radio Relay
Systems (DRRS) operating in the 13 GHz, 15 GHz and 18 GHz frequency bands with about 28 MHz co-polar and
14 MHz cross-polar channel spacing".

1 Scope
The present document specifies the minimum performance parameters for terrestrial fixed services radio
communications equipment, as given below, for operation in the 13 GHz, 15 GHz and 18 GHz frequency bands (i.e.
12,75 to 13,25 GHz, 14,50 to 15,35 GHz and 17,70 to 19,70 GHz).
The equipments covered by the present document are intended for operation with about 28 MHz basic channel spacing
with frequency re-use either in 14 MHz interleaved mode or in co-channel mode (definitions are in
ITU-R Recommendation F.746-4 [27]).
The present document covers equipment for the transmission of sub-Synchronous Transport Module level-1 (STM-1)
digital signals with a Virtual Container-3 (VC-3) payload capacity. The standardization of sub-STM-1 radio systems for
13 GHz, 15 GHz and 18 GHz bands has been prepared to ensure the compatibility with the existing plesiochronous and
the new synchronous systems concerning frequency plans and performance. The architecture and functional aspects
should be in accordance with ITU-R Recommendation F.750-3 [7] and transmission characteristics and performance
requirements in accordance with ITU-R Recommendation F.751-2 [8].
The present document do not cover aspects related to test procedures and test conditions which are currently under study
in TM4.
The application of these Digital Radio Relay Systems (DRRS) is anticipated to be for point-to-point links in local,
regional and national networks, mobile base station connections and customer access links. Consideration has to be
given to special requirements of the local network (e.g. simple towers with less space for antenna, different network
structures with high density nodes).
The systems considered in the present document are intended to operate on average hop lengths about 15 km for 18 GHz
band, 20 km for 15 GHz band and 30 km for 13 GHz band.
Equipment should be designed in order to meet network performance and availability requirements defined by ITU-T
Recommendations G.821 [18] and G.826 [19], following the criteria defined in ITU-R Recommendations F.634-4 [3],
F.695 [32], F.696-2 [5], F.697-2 [6], F.1092-1 [30] and F 1189-1 [31], for high or medium or local grade or the
international or the national portion of the digital connection.
The parameters to be specified fall into two categories:
a) those that are required to provide compatibility between Radio Frequency (RF) channels occupied by different
sources of equipment on the same route connected either:
- to separate antennas; or
- to separate polarization of the same antenna;
b) parameters defining the transmission quality of the proposed system.
The standardization deals with Intermediate Frequency (IF), RF and baseband characteristics relevant to sub-STM-1
Synchronous Digital Hierarchy (SDH) transmission. Spurious emissions and ElectroMagnetic Compatibility (EMC)
requirements are also included in the present document.
Safety aspects are outside the mandate of ETSI and they will not be considered in the present document.
