Future Digital Radio Relay Systems (DRRS) have to support the Synchronous Digital Hierarchy (SDH) defined by the ITU-T. Study Group (SG) 9 of the ITU-R in its final meeting in September 1989 approved a new report (CCIR Report 1190 [3]) dealing with general aspects of DRRS in an SDH Network and containing a list of items which need further study. Moreover, SG 9 has established Task Group (TG) 9/1 to study these very urgent aspects in the period between the meetings and to conclude its work before the next Interim Meeting of SG 9. TG 9/1 ended its duty in 1992 producing ITU-R Recommendations F.750 [1] and F.751 [2]. It was deemed very important that the items listed in section 7 of CCIR Report 1190 [3] will be carefully studied by TM4 as an urgent task and some clear statements produced.

The scope of the present document is limited to the requirements and architectures for HIPERLAN Types 2. HIPERLAN Type1 is addressed by ETS 300 652 [2] and its related Conformance Test Specifications, [2a], [2b], [2c] and [2d]. HIPERLINK will be described in a TR produced by BRAN. The requirements address subjects like applications, traffic volumes and traffic patterns that underlie the projected spectrum requirements as well as the chosen architectures. The architectures address the communications layer models as well as the Reference models that identify the key interfaces subject to standardization. The architectures developed in the present document are intended to delineate the boundaries between HIPERLAN standards and standards for networks in which HIPERLANs may be used as subsystems or components. Scope of standardization The scope of the standards for HIPERLAN Types 2 is limited to the air interface specifications, the Data Link Control (DLC) layer specifications, the specifications of the management functions and the interworking functions. The DLC layer specification includes a specification of the services to be provided. The ETSI HIPERLAN/2 standards specify subsystems up to and including the DLC Layer. Interworking functions will be specified in liaison with other relevant technical standardization bodies.

The present document provides the mapping scheme to be used for the transport of ATM cells over MPEG-2 Transport Stream packets. The purpose of encapsulating ATM cells directly into an MPEG-2 transport stream is to: • interconnect ATM networks via DVB systems or provide ATM services to end-users using DVB systems; • offer differentiated quality of service to end-users by utilizing the ATM mechanisms. The main constraints of this problem are to: • providing an efficient encapsulation mechanism; • maintaining DVB/MPEG-2 compatibility when transporting ATM cells; • respecting ATM Quality-of-Service requirements throughout DVB/MPEG systems.

The present document defines the major issues for the standardization of the general aspects of Digital Fixed Radio Systems (DFRS) formerly known as Digital Radio Relay Systems (DRRS) and for point-to-point specific equipment parameters, in order to maintain a generic format for the editorial and technical contents. It is also essential to maintain a common understanding of the reasons behind the way certain parameters are defined among the various DFRS standards, which deal with the same general topics and may differ from each other merely from the point of view of numerical requirements. The present document therefore also explains the reasoning behind why the parameters in DFRS standards are defined in the way they are. The present document aims to cover every issue that may be required. Specific standards may differ from the guidelines contained within the present document only if the specific argument is not covered or there is good technical reason for not following them.

The present document is intended as a companion document to the full specification, EN 300 706 [1], defining the data and transmission format within enhanced Teletext systems. It is primarily aimed at Teletext editors, service providers and network operators. The intention is to explain in relatively simple terms the new display features and possibilities that are available with enhanced Teletext. The focus is very much on which parts of a large and complex specification have to be implemented to produce a Teletext service that is more visually attractive than has been possible previously. The present document outlines the basic features of enhanced Teletext and highlights the key parameters for a successful service. It makes recommendations as to how aspects of the specifications should be implemented and suggests strategies to maximize the transmission efficiency of the additional data that will be required. It should be noted that the present document was compiled in advance of any first-hand experience in editing or operating an enhanced Teletext service. It is anticipated that a subsequent version will be able to draw upon the knowledge and experience that operating real services will bring.

Short duration transient disturbances can occur on dc power distributions when a short circuit fault occurs in part of that distribution. The energy contained in the transient can be sufficient to do considerable damage to equipment connected to the distribution unless measures are taken to suppress or absorb this energy. The present document examines the parameters of dc power distributions within the scope of EN 300 132-2 [1] that significantly contribute to the energy contained by a transient, discusses ways in which the transient can be controlled to reduce its harmful effects, and suggests ways in which the immunity of an electronic unit or a substantial telecommunications installation might be tested.

The test methods contained within the present document are intended for use in determining the electrical characteristics of radio equipment in the mobile radio services. A further aim is to give guidance to both manufacturers and type testing authorities so that common test methods can be adopted leading, potentially, to mutual acceptance of test results. Parameter limits specific to a particular equipment can be found in the relevant ETS (European Telecommunication Standard) or EN (European Standard, Telecommunications series). In the drive towards uniformity, the measurement of a specific equipment parameter has, basically, only one test method although, procedurally, minor differences may exist due to the type of test site used e.g. a ground reflection test site (Anechoic Chamber with a ground plane or Open Area Test Site) requires a vertical height scan to achieve maximum coupling between transmitter and receiver whereas a "non-reflecting" environment (Anechoic Chamber) does not. The methods apply to constant envelope frequency-modulated or phase-modulated systems as chosen by each administration operating on radio frequencies between 30 MHz and 1 000 MHz and with channel separations of 12,5 kHz, 20 kHz and 25 kHz. Test methods are given which are applicable to radio equipment capable of transmission and/or reception of analogue speech, bit stream and messages. Included in the present document are test method for radio equipment fitted with external 50 ΩRF connectors (for antennas), temporary external 50 ΩRF connectors and integral antennas. Wherever possible, if the electrical characteristics are not expected to be changed, test measurements should be performed by use of a direct connection (via either the permanent or temporary external 50 ΩRF connector) to the radio equipment as stated in each ETS or EN in order to attempt to minimize measurement uncertainties.
