The present document describes a railway application utilizing ultra wideband technology operating in the preferred frequency ranges from 3,1 GHz to 4,8 GHz and from 6 GHz to 8,5 GHz. Operation is foreseen for indoor and outdoor applications, including either mobile devices installed onboard the train cars and fixed devices installed on ground, as reference stations. These stations, belonging to the fixed infrastructure, will be allowed to operate as UWB emitters only in the lower frequency band, from 3,1 GHz to 4,8 GHz, in compliance with the compatibility studies and with the latest recommendation [i.9] proposed by ECC/CEPT, as this provision would allow the deployment of such fixed UWB devices in the railway environment according to the "registration and coordination" process recently proposed by ECC/CEPT 167 [i.10]. In railway applications, location tracking is performed within specified areas, called as an Area-Of-Interests (AOIs), which are areas around Point-Of-Interests (POIs). The POIs are listed below: • Point in passenger platform • Railway signal • Railway crossing • Generic POI The UWB radio technology is required to track with sub-meter accuracy any rail vehicle to the purpose of stopping it in the appropriate POI. The length of AOI is defined by the braking distance of a rail vehicle, and it is typically hundreds of meters. The generic regulation on UWB technology for use in rail and road vehicles onboard applications, such as - for instance - in subway underground stations, within the frequency ranges of 3,1 GHz to 4,8 GHz and 6 GHz to 8,5 GHz has been recently updated in the last Electronic Communication Committee (ECC) amended ECC/DEC(06)04 [i.1] including the suitable reference to mitigation techniques. According to [i.2], underground station should be considered as an indoor environment because surrounding structures shields any emitted radio signal, providing the necessary attenuation to protect primary radio communication services against harmful interference. However, in railway stations and trackside signalling installations there may not be structures blocking the propagation of emitted signals, and therefore the outdoor environment regulation should apply. The outdoor usage of UWB devices in location and tracking applications such as person and object tracking in industrial, automotive and transportation environments are described in [i.4] and [i.5]. Nevertheless, these applications do not include the location / tracking specific application in railway environments, which may occur at many points across a public rail or tram network. Actually, the latest generic ECC regulation [i.11] for the deployment of UWB devices in vehicles and the ECC/REC(11)09 [i.9] on provisions relevant to fixed UWB infrastructures do not deal with specific railway application issues, but are actually permitting the deployment of such UWB, respectively, onboard the trains and along the wayside of railway infrastructures. Therefore, the present document describes the railway application of UWB devices and collects specific information, including: • Market information (annex A). • Technical information (annex B).

The present document, is intended for complementing the ETSI EG 203 336 [i.1] for specific guidance related to Digital Fixed Radio Systems (DFRS) in the production of candidate harmonised standards covering Directive 2014/53/EU [i.2]. Consequently the present document should always be used in conjunction with ETSI EG 203 336 [i.1] whenever DFRS are concerned. NOTE: The previous versions of the present document were developed for similar purpose related to the now superseded ETSI EG 201 399 [i.10] V2.1.1 and Directive 1999/5/EC [i.11] repealed in June 2016 by Directive 2014/53/EU [i.2]. The present document identifies, among the generic technical parameters, relevant for the article 3.2 of the Directive, presently quoted by ETSI EG 203 336 [i.1], those which are relevant and applicable and those that are considered not applicable, for the various typologies of DFRS. Taking also into account the general principle of avoiding overregulation, they are justified through specific peculiarities of the DFRS technologies employed. Moreover it gives the cross reference from the generic terminology used in ETSI EG 203 336 [i.1] and that currently used within the Fixed Radio technical community. Considerations about technical parameters related to article 3.1 (health, safety and EMC) and article 3.3 (interworking and other special requirements) of Directive 2014/53/EU [i.2] are outside the scope of the present document.

The present document gives a set of requirements, observations and areas of further investigations to be used in order to base further actions in ETSI, regarding services that deal with presenting and restricting calling name information to users connected to PSTN or ISDN. The following supplementary services are within the scope of the present document: - Calling Name Identification Presentation (CNIP) is a supplementary service which is offered to the called user and which provides name information associated with the calling user (calling party name) to the called user; - Calling Name Identification Restriction (CNIR) is a supplementary service which is offered to the calling user to prevent presentation of the user's name information to the called user. The identification of requirements is based on analysing existing or emerging European standards and international recommendations on calling name information. Furthermore, due to the obvious clear analogy with CLI services, European standards on CLI management for PSTN and ISDN users have been taken into account. The CNIP and CNIR services on the PSTN and ISDN are offered in United States of America and Canada, where the market is more developed especially in terms of residential phone services and business applications. These services are considered enhanced CLI services. Within Europe some service providers are performing field trials. The following aspects are excluded from the scope of the present document: a) Interactions with supplementary services; b) Quality of service; c) Charging aspects.

The present document applies to RFID systems operating in the UHF band. RFID belong to the family of non-specific SRDs. It is anticipated that the frequency band proposed in the present document will be dedicated to non-specific SRDs. The present SR Doc is intended to define RFID systems that are used in item management and logistic applications. These applications require reading ranges of at least 2 m that cannot be provided by alternative technologies and at other frequencies. The operation of SRDs in the UHF band is covered by the generic standard EN 300 220-1 [2]. Some of the requirements proposed in this System Reference Document - particularly those relating to power levels - fall outside the generic standard. It will be necessary therefore to raise a new Work Item for the generation of suitable documentation to deal with these issues. The present document contains the technical characteristics for radio equipment referencing CEPT/ERC Decisions and Recommendation CEPT/ERC/REC 70-03 [1].

The present document describes a Common Reference Model for Broadband Radio Access Networks (BRAN) supporting ATM, also know as Wireless ATM Access Systems (WACS). WACS provide wireless local and remote access to ATM networks. In the ETSI BRAN Project, the scope of the standards for such specific systems is limited to the air interface, the service interfaces of the wireless subsystem, interworking functions for specified user and network interfaces, and supporting capabilities required to realize these services. The air interface and the interworking functions for HIPERLAN/2 provide multi-vendor interoperation capabilities at the air interface and at those supported network interfaces. Interfaces and protocols between the signalling functions in ATM terminal devices and the signalling functions in the ATM switch are outside the scope of BRAN, but may be in the scope of the present document where they relate to radio mobility. The following describes a reference model to be used as basis for the development of a set of functional standards for WACS. It should be noted that for many purposes, there is no need to distinguish between WACS compliant systems serving mobile user nodes and those serving stationary access nodes. In the latter case, the same node may be visible to more than one access point and the radio link conditions may require a "handover" in order to maintain communications in changing radio environments.

The present document is a guide how to implement and test Digital Enhanced Cordless Telecommunications (DECT) FWA (WLL) systems operating at frequencies outside the frequency-bands described in TBR 6 [9]. The need to have this arises if DECT equipment is to be adapted to national frequency allocations that differ from the basic 1 880 MHz to 1 900 MHz DECT frequency band. This includes not only the radio frequency band around 1,9 GHz, as stated in [19], but also the radio frequency bands for Fixed Services within 2 200 MHz to 105 GHz and has special focus on applications in the 3,4 GHz to 3,7 GHz band. The present document is thereby also a guide for approval of such DECT systems in the above mentioned countries.

The purpose of the present document is to analyse the threats due to IN interworking between IN structured network operators and/or service providers using CS2 and CS3. A set of technical requirements will be established in a following document. The present document analyses the attacks which could occur in the interworking relationships, the present document principally considers CS2 and will focus mainly on security problems linked to the use of SCF-SDF, SCF-SCF and SDF-SDF interfaces. These IN interfaces could be either the target of the attack or the means to perform the attack. The present document follows the successive steps: - listing vulnerabilities for IN architecture to the use of SCF-SDF, SCF-SCF and SDF-SDF interfaces; - description of threats (Intentional or accidental) and their impact; - determination of the likelihood of the attack based on the motivation of the attacker; - production of a risk assessment.

The information and advice in the present document applies primarily to TIPHON Scenarios 0 (all IP) and 2 (SCN to IP) but there are additional comments about Scenario 3 (SCN to IP to SCN). NOTE: The E.164 number will normally be presented as the calling number in the Calling Line Identity which is relevant to Scenario 1 (IP to SCN) but this is not a major influence on the choice of E.164 number.

The present document provides a collection of information and guidance relating to: - the choice of naming schemes; - the relationship of names to services; - the role of the proposed ENUM system; and - the resolution of names in the process of routing for the routing of public telephone calls (i.e. calls where the called party is identified by an E.164 number) to a terminating IP network or an IP network that supports a gateway back to an SCN. The calls may originate from or transit public IP based or SCN based networks. NOTE: This is intended to be approximately equivalent to the public telephone service defined in ITU-T Recommendation E.105. The present document is applicable to all networks that support the public telephony service and is therefore written on the basis that the E.164 numbering scheme is used for calling and called party identification. Nevertheless the underlying principles could also be applied with minor adaptation to private network numbering schemes. The present document applies to calls to most types of number structures within E.164 [13], and includes the support of carrier selection and number portability. It does not specifically address the support of mobility or roaming, although it would apply to the routeing of a call to the home mobile network. The types of IP network considered include but are not limited to TIPHON Release 3. Because the routing aspects of the present document focus mainly on routing between networks for the support of a common service (public telephony), the report has a different emphasis from the main emphasis of TIPHON Release 3, which is focused on the provision of customized services to the customers of a single service provider. The present document covers only the routeing between networks. It does not include the routeing inside a terminating network.

The present document describes the traffic capacity and the spectrum requirements for multi-system and multi-service Digital Enhanced Cordless Telecommunications (DECT) applications coexisting on a common frequency band. Configurations for typical DECT applications, and relevant mixes of these, including residential, office, public and Radio in the Local Loop (RLL) applications, are defined and the traffic capacity is analysed, mainly by advanced simulations. These results are used together with relevant deployment scenarios to estimate spectrum requirements for reliable services, specifically for a public multi-operator licensing regime. Recommendations are given on conflict solving rules that conserve the high spectrum efficiency gain of shared spectrum while maintaining control of the service quality in one's own system. These recommendations cover synchronization, directional gain antennas, traffic limits per DECT Radio Fixed Part (RFP), use of Wireless Relay Stations (WRSs), different rules for private and public operators and procedures needed for timely local adjustments where and when the local traffic increases. Results of studies on compatibility with other relevant radio technologies using spectrum adjacent to the DECT band, are also included.

The present document provides an introduction to the technical issues relating to the work items defined in the terms of reference of ETSI Project TIPHON [1] and offered with respect to the reference scenarios: Scenario 0: communication between 2 or more Internet Protocol (IP) network based users in which the call signalling and traffic are wholly contained within the IP network (in one or more domains). Scenario 1: communication between IP network based users and Switched Circuit Network (SCN) based users in which the call setup is originated by the IP network user. Scenario 2: communication between IP network based users and SCN-based users in which the call setup is originated by the SCN based user. Scenario 3: communication between SCN based users using IP based networks for the connection/trunking between the involved users. Scenario 4: communication between IP network based users using SCNs for the connection/trunking between the involved users. TIPHON shall primarily consider, but not be restricted to, the interaction of H.323 terminals on IP networks with telephone terminals on SCNs. The TIPHON project shall develop standards, and profiles of existing standards, for each of the above profiles. New standards shall be developed only where no existing standards exist. Where existing standards exist in ETSI, ITU or elsewhere ETSI Project TIPHON shall work with the standards bodies in developing and promoting profiles of those standards. These standards shall include an Open Settlement Protocol. The TIPHON project shall not specify any new bearer services. However the TIPHON project deliverables shall be able to request certain QoS constraints that may restrict the ability of any particular bearer service to support TIPHON teleservices (particularly with respect to QoS and bandwidth). The present document is structured as follows: - clause 4 provides an overview of the TIPHON project work area; and - clause 5 introduces and describes the reference scenarios of the TIPHON project. The present document will not provide solutions for the technical issues that are identified therein.

The present document applies to the physical layer and associated signalling of the air interface of Autonomous Satellite Signalling Channels (ASSCs) between user Satellite Terminals (STs) and Gateways (GWs), or between STs, for satellite access systems where inbound and outbound channels are independent from each other. In these systems, the inbound channels of a Satellite Terminal are those channels carrying data, and transmitted from the Satellite Terminal to Gateways or to other Satellite Terminals. The outbound channels of a Satellite Terminal are those channels carrying data, and received by the Satellite Terminal from the Gateways or other Satellite Terminals. The inbound and outbound channels may be of any type. These satellite access systems are designed to provide end-users with multi-services such as data transfer, telephony and associated services, data gathering, etc. These systems are designed to offer two way links for traffic between end-user Satellite Terminals and service providers connected to Gateways, or between end-user Satellite Terminals. In these systems, the inbound channels from Satellite Terminals and the signalling to and from the Satellite Terminals are transmitted through the same satellite. In these systems, the inbound channels from Satellite Terminals and the outbound channels towards Satellite Terminals may be transmitted through the same satellite or via different satellites, and to and from the same gateway or different gateways. These satellite access systems are operated through geostationary satellites, in the Fixed Satellite Service frequency bands. In these systems, the STs are designed usually for unattended operation. The interfaces of GWs with the terrestrial networks and the interfaces of STs with the user terminals or local networks are outside the scope of the present document.

The present document provides implementation guidelines for the use and implementation of the DVB Service Information (SI) coding in a DVB digital TV environment including satellite- cable- and terrestrial networks. The guidelines are intended to be highly recommended rules for the usage of the DVB SI syntax specified in ETSI EN 300 468 [1]. As such, they facilitate the efficient and reliable implementation of basic user-interaction functions in Integrated Receiver-Decoders (IRD). The rules apply to broadcasters, network operators as well as manufacturers. The rules are specified in the form of constraints on the DVB SI streams or in terms of intended interpretation by IRDs. The specification of these functions in no way prohibits IRD manufacturers from including additional features, and should not be interpreted as stipulating any form of upper limit to the performance. The guidelines do not cover features related to user-interface details or advanced Electronic Program Guides (EPG). Such issues are left to the marketplace. NOTE: It is highly recommended that the IRD should be designed to allow for future compatible extensions to the DVB SI syntax. All the fields "reserved" (for ISO), "reserved_future_use" (for ETSI), and "user defined" in the ETSI EN 300 468 [1] should be ignored by IRDs designed not to make use of them. The "reserved" and "reserved_future_use" fields may be specified in the future by the respective bodies, whereas the "user defined" fields will not be standardized. The present document uses the terminology defined in ETSI EN 300 468 [1] and should be read in conjunction with that EN.

To investigate radio and network aspects and clarifying the possibilities, problems and needs for new standardization related to advanced dual-mode terminals for DECT and GSM. The present document will identify the needed contents of the necessary standards that will form the basis for the second edition of Harmonized Standard EN 301 439 [18], i.e. dual-mode terminals that cannot be type approved according to existing TBRs and Harmonized Standards and that may operate in both modes at the same time or using only a single subscription. Basic dual-mode terminals, i.e. terminals consisting of one DECT part and one GSM part and that can be type approved according to existing TBRs and Harmonized Standards, were considered in another ETR (TR 101 072 [16]). The same consideration should be made for dual-mode terminals and infrastructure for DECT/DCS1800 as well as dual-mode/dual-band terminals DECT/GSM/DCS1800. The term GSM is considered to cover all the frequency bands, and combinations of frequency bands, allowed for GSM type equipments, i.e. P-GSM, E-GSM, R-GSM, DCS1800 or dual-band GSM/DCS. NOTE: A terminal comprising multiple GSM parts operating on different frequency bands is considered as a dual- band terminal. A terminal comprising both DECT and GSM parts is referred to as a dual-mode terminal.

The present document is to describe Number Portability. For the purpose of this study Number portability is limited to the Service Provider Portability for Geographic Numbers (GNP) and Non Geographic Numbers (NGNP) in the National Fixed Network, e.g. number portability between Service Providers within geographic country boundaries. An exception to this is Number Portability of the European Telephony Numbering Space. In order to describe number portability, the present document provides: - an overview of number portability; - a description of the responsibility of the different entities involved; - a description of number portability in the European Telephony Numbering Space (ETNS); - background material to concepts used in related documents TR 101 118 [1], TR 101 122 [2] and EG NA-061501 [3] describing: - possible internal architectures; - numbering and addressing; - signalling; - Intelligent Network (IN) Options. The present document describes the responsibilities of the various entities involved in number portability in order to deliver calls to numbers that have been ported. The present document also identifies the information requirements of the various entities necessary to manage and implement Number Portability. Service management and inter-operator procedures have been demonstrated to be the major area of difficulty when introducing number portability. Detailed considerations of these issues are outside the scope of the present document The scope of the requirements is limited to: - the portability of individual customer numbers; - porting of individual Multiple Subscriber Number (MSN); - porting of complete Direct Dialling In (DDI) ranges. However, whilst it is not possible to port single numbers from a DDI range, dividing the range into blocks and porting the resultant sub block will have the same effect. Therefore there is no need to support the portability of individual numbers within a DDI range. The results of the study should ensure: 1) Architectural Flexibility: the set of architectures selected for support of number portability should allow network operators reasonable flexibility in the manner in which the architecture is implemented, the use of equipment from multi vendors; 2) Transparency: the mechanism by which portability is provided should be transparent to the ported and non ported customers; 3) Performance: the mechanism by which portability is provided should subject the call to minimal (if any) performance degradation relative to that offered to non ported numbers. This includes both post dial delay and transmission; 4) interconnection: All network operators offering portability within the same geographic area should interconnect, either directly, or via a transit, and complete calls. Direct or transit interconnection is a commercial decision. 6 TR 101 119 V1.1.1 (1997-11) The following Portability types are out of the scope of this study, but are described for completeness: - service Provider Portability for Mobile Numbers; - service Portability; - location Portability. The impact of a ported non geographic number resolving to a geographic number has been raised as an issue, and is for further study.

The term PCI stands for Programmable Communication Interface, sometimes also referred to as Programming Communication Interface. A PCI presents a specialized Application Program Interface (API) that is related to the communications aspects of software. The present document deals with the requirements of PCIs for multimedia applications, i.e. digital applications that combine independent isochronous and asynchronous media types together. Multimedia applications can be interactive or not. They may use and/or present different types of media either in context, or simultaneously or in loose conjunction with each other. Different types of applications and different types of media like audio, video, voice or images, impose different requirements onto the terminal equipment and the underlying communications networks. The impact of those applications and media, and the abilities of the communications networks are studied thoroughly. The demands of the (human) users are considered carefully. The present document analyses the different requirements by applying different viewpoints, which illuminate the viewpoint-specific impacts and demands. The summary of the results form a general list of requirements for PCIs for multimedia applications. Those requirements are then compared against existing PCIs. As result a detailed list of requirements for each type of PCI is obtained. Moreover, the present document structures the existing and future PCIs in accordance with existing PCI models and discusses briefly the need for future extension or creation of specific PCIs. The general title of the present document reads "Generic PCI for multimedia applications". Since this title might mislead the reader in the sense that possibly one - and only one - PCI might exist that covers all the applications needs, the reader should note that the complexity of multimedia applications disallows this approach. Several - in nature completely different - PCIs will be needed to cover the world of multimedia applications. This becomes even more apparent, if it is considered that future multimedia applications will probably extend to run in new kinds of terminal equipment that is not even yet available. The present document identifies the Programmable Communication Interfaces (PCIs) needed for today and future multimedia aware applications. It points out: - what kind of PCIs are needed; - what kind of features those PCIs shall provide; - what kind of suitable PCIs are already defined (or standardized) by standardization bodies; - how existing definitions of those PCIs should be extended to cover the needs of multimedia aware applications.

The present document summarizes the users' views on the main issues related to private directory systems from a functional point of view. It deals with the design of these systems, their interworking as well as interworking between private directory systems and public ones. The present document is applicable to private directory system design and provision. It should be seen as a source of guidelines to users. A corporate directory is an implementation of a private directory for large companies. It is here defined as a repository for information shared by all departments in a corporation, an organization, or an institution. A corporate directory is in contrast to the situation where different departments and functions maintain their own directories for their own purposes, and where such directories are not integrated to constitute an integrated appearance to all users. This does not necessarily imply that a corporate directory needs to be centralized or centrally managed. There are several directory technologies available. Issues concerning establishing a corporate directory are to some degree dependent on the selected technology. Most concepts given in the present document refer to the X.500 directory technology. It does not assume that the reader has a deep understanding of that technology. It is the intention here to keep the technical details down to a minimum. However, it is not possible to discuss deployment of a directory without referring to some X.500 directory concepts, like naming and information structures. Annex A gives a short introduction to the basic X.500 concepts for the benefit of those readers not familiar with such concepts. Although EWOS closed in 1997 and a new organization ISSS (Information Society Standardization System) has been set up to continue producing specifications in same area, EWOS publications remain available for downloading. Therefore, some additional tutorial information can be found on the EWOS Web-pages: http://www.ewos.be/dir/gtop.htm [12] Nevertheless, as indicated in subclause 6.4 "Directory schema", interworking between the different directory systems implies conformance to some X.500 key concepts. In the remainder of the present document, concepts like Directory Information Tree (DIT), directory entry, Distinguished Name (DN), Relative Distinguished Name (RDN), Directory System Agent (DSA), Directory User Agent (DUA), Directory Management Domain (DMD), etc. are assumed to be known by the reader.

The present document is to investigate, address and describe possible High level Network Architectures and Solutions for Number Portability of ITU-T Recommendation E.164 [3] numbers in the fixed telecommunications Network. The following is included in the present document: a) possible Network Architectures and solutions to support number portability; b) Pros and Cons for described Number Portability solutions and influences on services; c) management issues with regard to NP and selected Data Base solution; d) the exchange of NP related information between Networks per solution; e) routeing issues with relation to NP and described solution. The following types of number portability is to be covered: 1) service provider portability of Geographic Numbers; 2) service provider portability of Non Geographic Numbers. NP solutions both for Routeing of ordinary calls and for Routeing of connection less supplementary services (e.g. CCBS) are included.

The present document identifies the key technical issues and problems of completing the integration of ASN.1 (as defined in the ITU-T Recommendations X.680 [1], X.680 Amendment 1 [2], X.681 [3], X.681 Amendment 1 [4], X.682 [5] and X.683 [6]) and SDL (as defined in ITU-T Recommendations Z.100 [7] and Z.100 Addendum 1 [8]). The present document also identifies the key technical issues and problems of integrating ASN.1 (as defined in the ITU- T Recommendations X.680 [1], X.680 Amendment 1 [2], X.681 [3], X.681 Amendment 1 [4], X.682 [5]) and X.683 [6] and the second version of TTCN (as defined in ISO/IEC 9646-3 [11]). The present document focuses on types and does not investigate representation of values. It is intended that the proposed solutions stated in the present document be used as a basis for further work by ETSI (or others). The present document complements rather than supplants ETR 60 [12] and ITU-T Recommendation Z.105 [9].
