Question 18/15

Question 18/15 - Broadband in-premises networking
(Continuation of Question 4b/15)
The continuing customer demand for ever higher bit rate data services, high-speed Internet access and other innovative services, and the ongoing needs of network operators to leverage in-premises connectivity for distributing within the home IPTV and other applications, will require the development of new Recommendations and enhancements to existing Recommendations covering all aspects of in-premises Networking Transceivers operating over metallic conductors. These studies will include, but are not limited to, the transport of higher layer protocols, the management and test of the in-premises systems, spectral management aspects and energy saving techniques.
The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: G.9951 through G.9954, G.9960 through G.9964, and G.9972.
The target audience for this question are the technology suppliers, chipset vendors, equipment vendors, and service providers active in the domain of providing broadband in-premises networking. A global audience is targeted to facilitate a unified approach to the broadband in-premises networking.
What enhancements are needed to the G.9951 through G.9954, G.9960 through G.9964, and G.9972 Recommendations:
  • in the light of design, network deployment experience, and evolving service requirements?
  • to optimise the transport of IP-based services?
What new Recommendations are needed:
  • for broadband transceivers for in-premises networking over metallic conductors such as phone-line, coaxial, data (e.g. CAT5) and power cables?
  • to carry out line testing?
  • to enable higher bit rates to be achieved by means of MIMO?
  • to enable transport of higher layer protocols?
  • to optimize the quality-of-experience to the end user?
  • to facilitate PLC coexistence?
  • to facilitate inter-domain communication between different mediums to optimize the choice of delivery path for data and ensure end-to-end QoS?
  • to support timing synchronization mechanisms necessary for audio/video delivery?

What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries?

What enhancements to developing or new Recommendations are required to provide such energy savings?
Study items include, but are not limited to:
  • Modulation and transport techniques, tools for spectrum management (including dynamic spectrum management), real noise environments, handshaking procedures, testing procedures, physical layer management procedures, protocols for PLC coexistence, energy saving techniques.
  • These studies should take account of the different regulatory environments around the world.
  • Transceiver to higher layer inter-connection techniques
These studies will include any specific requirements:
  • to optimise the transport of IP-based services
  • to optimise the transport of Ethernet based services
  • to support the management of in-premises networking systems operating over metallic conductors
Tasks include, but are not limited to:
Maintenance and enhancements of existing Recommendations G.9951 through G.9954, G.9960 through G.9964, and G.9972, and production of new Recommendations in the G.996x, and G.997x series.
