Question 4

Broadband access over metallic conductors

(Continuation of Question 4/15)

Motivation
The continuing customer demand for ever higher bit rate data services, high-speed Internet access and other innovative services, and the on-going needs of network operators to fully exploit their installed base of metallic conductors (including copper pair and coaxial cables), will require the development of new Recommendations and enhancements to existing Recommendations covering all aspects of Transceivers operating over metallic conductors in the access part of the network, extending into the customer premises. These studies will include, but are not limited to, the transport of higher layer protocols, the management and test of the access systems, spectral management aspects and energy saving techniques.

G.fast and emerging technologies will raise bit rates to 2 Gbit/s and beyond by combining the best aspects of optical, coaxial, and DSL technologies in hybrid systems with total wire length to the customers’ transceiver up to 400 m, and by using higher bandwidth profiles, and/or bonding.

The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility: G.991.x series, G.992.x series, G.993.x series, G.994.1, G.996.x series, G.997.x, G.998.x series, G.999.1, and G.970x series.

The target audience for this question are the technology suppliers, chipset vendors, equipment vendors, and service providers active in the domain of providing access to a high-speed network from the customer premises. A global audience is targeted to facilitate a unified approach to the broadband access over metallic conductors.

Question
What enhancements are needed to the G.99x and G.970x series of Recommendations:

What new Recommendations are needed:

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:
These studies should take account of the different regulatory environments around the world.

These studies will include any specific requirements:

Tasks
Tasks include, but are not limited to:

Maintenance and enhancements of existing Recommendations and production of new Recommendations in the G.99x (e.g., G.991.x series, G.992.x series, G.993.x series, G.994.1, G.996.x series, G.997.x, G.998.x series and G.999.1) and G.970x series.
