Technical Committee (TC) Access, Terminals, Transmission and Multiplexing (ATTM) Activity Report 2023

Chair: Dominique Roche, Association eG4U

Responsible for the standardization of:

  • Access, terminals, transmission and multiplexing, including cabling, in-building power line technology, fixed radio equipment for access and mobile backhauling, installations, signal transmission and other forms of signal treatment up to digitalization, in the private and public domains, focusing on the specific technology, equipment, installations and regulatory aspects of the physical layer.
  • Operational KPIs to monitor global sustainability of ICT deployed services & networks in the field (e.g. Global KPIs, Smart Cities KPIs).

ETSI’s Access, Terminals, Transmission and Multiplexing committee (TC ATTM) addresses operational and physical parts of ICT including broadband transmission networks, equipment and sites.

TC ATTM works closely with ETSI’s Industry Specification Group on Operational energy Efficiency for Users (ISG OEU). These groups share the aim of improving the implementation of efficient ICT services, and increasing sustainability efficiency in operational networks and devices, as well as improving energy management efficiency and management of ICT waste in the operational period from implementation until end of life. The committee also shares information with other ETSI technical bodies including TC eHEALTH, TC CABLE, TC EE, TC RRS, TC SmartM2M, oneM2M, ISG F5G and ISG mWT.

The work of TC ATTM aligns closely with ETSI’s European SDO peers CEN and CENELEC in areas of shared interest, notably via active participation in the CEN-CENELEC-ETSI Coordination Group on Smart Grid (CG SG). On this topic TC ATTM participated in the ETSI Summit on Sustainability for green and sustainable networks and cities held in March 2023.

The committee interacts with the following external bodies, notably:

  • CENELEC TC215 'Electrotechnical Aspects of Telecommunication Equipment' in relation to VDSL2 test signals;
  • CENELEC TC209 'Cable networks for television signals, sound signals and interactive services' regarding safety on RPF over Coax;
  • CENELEC TC86BXA 'Fibre optic interconnect, passive and connectorised components';
  • Broadband Forum (RPF over Coax);
  • ITU-T SG5 (system and function access energy efficiency in 5G networks);
  • ITU-T SG15 (Networks, Technologies and Infrastructures for Transport, Access and Home);
  • ISO/IEC JTC1/SC25 (Interconnection of information technology equipment);
  • ISO/IEC JTC1/SC39 (Sustainability; IT and Data Centres);
  • ISO/IEC JTC1/WG11 (smart cities).

 Working Group AT2 on Infrastructure, Physical Networks & Communication Systems

ATTM Working Group AT2 (Infrastructure, Physical Networks & Communication Systems) is responsible for the creation, development and maintenance of standards and specifications covering cabling, installations, communications systems and network services implementation. During 2023 development continued on various reports and specifications:

  • Revised Technical Specification TS 105 174-5-4 on Broadband Deployment and Energy Management; Part 5: Customer network infrastructures; Sub-part 4: Multi-tenant premises (residential and commercial).
  • Technical Report TR 105 174-5-5 on Broadband deployment and Energy Management; Part 5: Consumer Network Infrastructures; Sub-part 5: Operational implementation of sustainable digital multi service multi tenant premises and campus.
  • Technical Specification TS 103 933 on Fibre deployment for fibre-based in-premises networking.
  • ETSI Standard ES 205 200-8 on Global KPIs for ICT Sustainability & Efficiency; Part 8: Global KPIs for improved WEEE management dedicated to users.
  • Technical Specification TS 104 021-1 on ODN Quick Construction and Digitalization; Part 1: General and Guidance.

Sustainable Digital Multiservice Communities

The Working Group on SDMC (Sustainable Digital Multiservice Communities) in TC ATTM is responsible for the creation, development and maintenance of standards and other deliverables in regard to the relationship between deployment of ICT systems and implementation of services within cities and communities.

A workshop organized by ATTM SDMC on digital technologies for smart and sustainable cities was held in Montrouge (9-10 February 2023) with the collaboration of EC DG Connect, EUROCITIES network, and the Metropole Grand Paris. The successful event focused on digital, efficient and eco-responsible innovations in the service of local authorities.

Further to ISG OEU request, SDMC started to work on Building Information Modelling (BIM). A series of standards should be developed to define Data interoperability format with applications for connected buildings.

During 2023 development continued on various specifications and other Work Items:

  • Technical Specification TS 102 874-7 on External Common Power Supply for Customer Premises Network and Access Equipment; Part 7: Adaptive and multiple output power supplies based on USB Type C connector and USB PD support.
  • Revised ETSI Standard ES 202 874-1 on External Common Power Supply for Customer Premises Network and Access Equipment; Part 1: Functional requirements.
  • Revised Technical Specification TS 110 174-1-1 on Broadband Deployment and Energy Management; Part 1: Societal and technical pillars for sustainability; Sub‑Part 1: Overview, common and generic aspects of societal and technical pillars for sustainability.
  • Revised Technical Specification TS 110 174-1-2 on Broadband Deployment and Energy Management; Part 1: Societal and technical pillars for sustainability; Sub‑Part 2: Governance directives for an eco-responsible policy for Digital Communities.
  • Revised Technical Specification TS 110 174-1 on Broadband Deployment and Energy Management; Part 1: Overview, common and generic aspects of societal and technical pillars for sustainability.

Working Group TM4 (point-to-point and multipoint fixed radio systems):

Working Group TM4 develops specifications for point-to-point and multipoint radio systems in the fixed service, used in core and access networks, including mobile service backhauling. During the year TM4 made revisions, for updates required by market and technology evolutions, to various European Standards and accompanying Harmonised European Standards, including deliverables in response to the M/536 under the Radio Equipment Directive (2014/53/EU).

Activity in TM4 accordingly progressed on several Work Items, including:

  • Revision of EN 302 217-4 on Characteristics and requirements for point-to-point equipment and antennas; Part 4: Antennas.
  • Revision of EN 302 217-1 on Characteristics and requirements for point-to-point equipment and antennas; Part 1: Overview, common characteristics and requirements not related to access to radio spectrum.
