Technical Committee (TC) Integrated Broadband Cable Telecommunication Networks (CABLE) Activity Report 2021

Chair: Volker Leisse, CableLabs

Responsible for standardization related to integrated broadband cable telecommunication network technologies.

ETSI’s Integrated Broadband Cable Telecommunication Networks committee (TC CABLE) develops standards addressing the evolution of the capabilities of broadband cable networks. The committee cooperates with several other ETSI technical bodies, contributing its expertise on cable technologies and assessing potential impact on integrated broadband cable telecommunication networks and services.

The committee’s work leverages close relationships with the Society of Cable Telecommunications Engineers (SCTE), CENELEC (especially TC209) and ITU-T (especially SG9). In parallel, TC CABLE works with the wider global cable community to foster innovation and competitiveness, making technology available industry-wide based on voluntary standards.

The committee’s deliverables primarily relate to standards concerning:

  • Integrated broadband cable telecommunication network terminals, including cable CPE devices and network terminating devices,
  • Network infrastructure, including network topologies, HFC (hybrid fibre-coax) network distribution, data over cable systems, and frequency management,
  • Service, security, energy efficiency and sustainability aspects of integrated broadband cable telecommunication networks.

During 2021 the work of TC CABLE featured the development of a new multi-part standard covering the sixth generation transmission systems for interactive cable television services - IP cable modem. The standard is based on the specifications for DOCSIS® 4.0 and will enable multi-Gbps symmetrical services in the cable access network.

Progress was also made on development of other Work Items, including revisions to existing deliverables such as:

  • Multi-part standard (European Norm) on energy management; operational infrastructures; global KPIs:
    • EN 305 200-4 on design assessments; with
      • Sub-part 1: general approach
      • Sub-part 2: ICT sites in the core network
      • Sub-part 3: edge facilities
      • Sub-part 5: monitoring and operations support systems.
    • EN 305 200-2-4 on operational assessment in cable access networks.
    • EN 305 174-6 on broadband deployment and energy management in cable access networks.
  • Technical Specification (TS 103 128) on network performance measurement methods for broadband data services.
  • Technical Report (TR 103 785) on mapping of cable equipment and standards to support assessment of conformity with the European Commission’s Radio Equipment Directive (RED), the Electromagnetic Compatibility (EMC) Directive, and the Low Voltage Directive (LVD) covering safe operation of electrical equipment for consumer and professional use.
  • Technical Specification (TS 103 469) on performance characteristics of coaxial cables used for RF signal transmission in hybrid fibre-coax (HFC) telecommunication networks.

Publication of many of the above deliverables is anticipated in 2022.
