Technical Committee (TC) Access, Terminals, Transmission and Multiplexing (ATTM) Activity Report 2020

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 collaborates 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. 

In 2020, TC ATTM continued its development of Global Key Performance Indicators (KPIs) to support the deployment of eco-efficient networks and sites and to monitor the energy management of deployed broadband. Used to define green sites and networks for all industrial and commercial users, these KPIs are outlined in a series of ETSI Standards (ESs) based on TC ATTM’s existing KPIs and Technical Specifications (TSs) for energy efficiency in broadband deployment. These new ESs and existing TSs are complementary to European Standards (ENs) for the installation of efficient networks and sites which are being developed by CENELEC.

In the area of fixed radio systems we revised two parts of our standard [EN 302 217‑1, EN 302 217-2] on point-to-point equipment and antennas. The second part – addressing harmonized spectrum requirements for systems in the 1 - 86 GHz range – subsequently achieved Citation in the Official Journal of the EU. Also relating to fixed radio systems, we published a Technical Report [TR 103 712] exploring the role of PtMP (point-to-multipoint) solutions in addressing 5G network backhaul challenges.

In addition we updated our Technical Report on fixed radio systems [TR 101 506 Ver. 2.2.1] that addresses generic definitions, terminology and applicability of essential requirements covering article 3.2 of Directive 2014/53/EU.

We updated parts of our Technical Specification [TS 105 174-2, TS 105 174-5-1] on broadband deployment and lifecycle resource management, relating to customer network infrastructures (single tenant homes) and ICT sites.

We revised part of our specification [TS 103 463-1] describing Key Performance Indicators (KPIs) for sustainable digital multiservice areas. We also revised the first part of our specification [TS 101 548-1] on European requirements for reverse powering of remote access equipment, relating to twisted pair networks.

We published two new Technical Reports: one [TR 105 177] presents a benefit analysis of Ethernet and Power over Coaxial cables in IP video surveillance case studies; the other [TR 105 178] compares sustainability parameters between internal/external and cloud-based ICT hosting solutions.

Following the earlier absorption of ETSI’s Powerline Telecommunications committee (TC PLT), TC ATTM continued in 2020 to maintain specifications produced by PLT, while maintaining collaboration with other relevant Standardization Organisations. Work re-started on coaxial transmission in order to complete standardization of video surveillance deployment.

During the year, SDMC – the main group in ETSI supporting Sustainable Multiservice Digital Communities standardization – continued to develop standards for smart urban and rural areas with the support of AT2. In parallel, work on smart areas in AT2 continued to study the general engineering of building and campus networks.

Plans led by TC ATTM’s Working Group on Sustainable Digital Multiservice Communities (SDMC) for a physical Smart Cities and Communities Roadshow were postponed due to the pandemic situation. Replacing this, a first online event managed with Montrouge/Grand Paris has been scheduled for the first half of 2021.

During 2020 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
