Technical Committee (TC) Access, Terminals, Transmission and Multiplexing (ATTM) Activity Report 2021

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 the operational and physical parts of Information and Communications Technologies (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). The two groups share the aim of improving the implementation of efficient ICT services (e.g. SmartM2M and oneM2M solutions) 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: 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. These include the operational sustainability and energy efficiency of smart cities and communities, conducted via the mechanism of the Installations and Cabling Co-operation Group. The committee also liaises with other external bodies, notably ITU-T SG5 (system and function access energy efficiency in 5G networks), ITU-T SG15 (networks, technologies and infrastructures for transport, access and home) and ISO/IEC JTC1/WG11 (smart cities). 

Working Group AT2 on Infrastructure, Physical Networks & Communication Systems

Published in August 2021, TR 103 775 is a Technical Report on Optical Distribution Network (ODN) Quick Construction and Digitalization solutions, enabling carriers to improve fibre deployment efficiency and optimize digital resource management.

During the year AT2 meanwhile progressed several Work Items, notably:

  • Revision of Technical Specification TS 105 174-5-4 on broadband deployment and energy management in consumer network infrastructures, addressing implementation of sustainable digital multi-service networks in multi-tenant residential and commercial premises and campuses,
  • Revision to Technical Specification TS 102 873 on optical external network testing interface, to align with CENELEC documents EN50173-1, EN50173-4 and EN 50700,
  • Revision to TS 101 573 on general engineering of optical building cabling, to align with CENELEC documents EN50173-1, EN50173-4 and EN 50700,
  • Development of ETSI Specification on Carbon Intensity Management; operational infrastructures; implementation of global KPIs (Part 3: ICT Sites; Sub-part 2: DCCM). 

Sustainable Digital Multiservice Communities

Organized by TC ATTM’s Working Group on Sustainable Digital Multiservice Communities (SDMC), a successful online event on standardization perspectives in smart cities and communities was held on 22 April in collaboration with the EUROCITIES network and the Montrouge area in Grand Paris. Postponed from 2020 due to the pandemic, the event attracted 61 participants. Plans are currently in development for further workshops, with the next event planned to be held in Milan.

SDMC also progressed work on revisions to Part 1 of its Technical Specification on Broadband Deployment and Energy Management, that considers aspects of societal and technical pillars for sustainability in digital multiservice cities and communities. 

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

During the year TM4 published revisions 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):

  • EN 302 326-2 V2.1.1 on multipoint equipment and antennas; Part 2: Harmonised Standard for access to radio spectrum for digital multipoint radio equipment, aligning with requirements of Article 3.2 of the 2014/53/EU Directive (RED) – delivered to the EC in anticipation of citation in the OJEU.
  • EN 302 326-3 V2.1.1 on multipoint equipment and antennas; Part 3: multipoint antennas.
  • EN 302 217-1 V3.3.1 on characteristics and requirements for point-to-point equipment and antennas for Fixed Radio Systems; Part 1: overview, common characteristics and requirements not related to access to radio spectrum.
  • EN 302 217-2 V3.3.1 on Fixed Radio Systems; characteristics and requirements for point-to-point equipment and antennas; Part 2: Digital systems operating in frequency bands from 1 - 86 GHz; Harmonised Standard for access to radio spectrum – delivered to the EC in anticipation of citation in the OJEU.
  • EN 301 390 V2.1.1 on Fixed Radio Systems; point-to-point and multipoint systems; unwanted emissions in the spurious domain and receiver immunity limits at equipment/antenna port of Digital Fixed Radio Systems.

Work in TM4 meanwhile progressed on several Work Items, notably:

  • Study on characteristics and requirements for W- and D-band point-to-point equipment and antennas, for possible inclusion in EN 302 217 series
  • Study on implications of extending channels-aggregation systems to more than two channels emitted from a multi-channel antenna port, for possible inclusion in EN 302 217 series
  • PP passive antennas - preliminary study on RPE for 92-114.25 GHz and 130-174.8 GHz bands
  • Study on characteristics and requirements for active (time varying) antenna and related radio specifications used in PP FS bands

Working Group TM6 (Wireline Access Network Systems)

Published in June, TS 101 548-2 is the second part of the Technical Specification ‘European Requirements for Reverse Powering of Remote Access Equipment’. It defines architectures and specifications for reverse powering of a remote network node from one or multiple CPEs over Point to Point (P2P) coaxial cable, where there is no coexistence with other services over an operational Hybrid Fibre Coax (HFC) network.

During 2021 TC ATTM maintained its ongoing interaction with several external bodies:

  • CENELEC TC215 ‘Electrotechnical Aspects of Telecommunication Equipment’ in relation to VDSL2 test signals and physical infrastructure of optical networks for ICT premises
  • 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 SG15 (xDSL, and reverse powering, physical networks)
  • ISO/IEC JTC1/WG11 (smart cities)
  • ITU-R WP5C (fixed wireless systems)
  • ECC WGPT SE19 (fixed service)
