ITU-T Study Group 15 List of Questions Under Study (Study Period 2005-2008) |

ITU-T SG 15 Question 1/15 |
|
Coordination of access network transport standards (Continuation of Question 1/15)
- Motivation
Within ITU-T, transport in the access network is under study in a number of
different study groups, e.g. SGs 9, 13, 15, with several Recommendations
published, others in development, and other supportive activities conducted,
such as workshops. Moreover, ITU-R, IEEE and other standards bodies,
forums and consortia are also active in this area.
Recognizing that without a strong coordination effort there is the danger
of duplication of work as well as the development of incompatible and
non-interoperable standards, the WTSC-96 designated Study Group 15 as
Lead Study Group on Access Network Transport within ITU-T.
An Access Network Transport (ANT) Standards Overview and an ANT Work Plan
have been published. The ANT Standards Overview describes various Access
Network Transport "scenarios" currently being developed and implemented
and a list of associated Recommendations and Standards relating to/defining
those scenarios.
The ANT Work Plan lists a number of standardization bodies active in the
ANT area with names and addresses for contact, communication and collaboration.
It also lists possible "gaps", “overlaps" and conflicts of ongoing
standardization activities. Both are published on the ITU-T Study Group 15
website.
Worldwide, technology is advancing rapidly in Access Networks. As many as
100,000,000 subscribers worldwide use broadband connections to the Internet.
Sixty-four million connect using Digital Subscriber Line (DSL) technology
on telephone networks installed primarily by ITU-T member organizations.
Many broadband subscribers receive service from new or non-traditional
providers, via traditional telephone networks or by other networks such
as coaxial cable in Community Access Television (CATV) networks, wireless
providers or even via electric power distribution grids. Finally, there
is enormous interest in developing nations for rapid broadband deployment
in order to accelerate economic growth as well as to close the digital divide.
In summary, the Access Network is experiencing rapid technical change,
historic high subscriber growth rates, a proliferation of new products
and solutions, wide entry from new service providers and equipment suppliers
who can be unfamiliar with general standards and governments eager for
deployment of advanced technologies in the Access Network. The need for
coordinated standardization in this market has not been greater
than it is today.
- Question
How can ITU-T Study Group 15 best fulfil its mission as Lead Study Group
on Access Network Transport within ITU-T?
Study items to be considered include but are not limited to:
- Maintain and update the ANT Standards Overview together with other
study groups and in conjunction with ITU-R and other relevant organizations
- Maintain and update the ANT Work Plan, report ANT related standards
activities underway by recognized Standards Developing Organizations (SDO’s),
identify "gaps, overlaps and conflicts" by observing ongoing standardization
activities
- Maintain and update the ANT web presentation
- Maintain coordination across the relevant ITU-T study groups to
ensure all available expertise is utilized to best advantage and in
the establishment of priorities
- Serve as focal point to and provide coordination with other standards
organizations, forums and consortia to ensure that the consolidation
of work plans and priorities is based on a wide range of business,
market and technological inputs
- Contribute to ITU efforts to support developing countries by making
pertinent information available such as ANT standards, documents and
relevant information including indications of best practices on implementation
of broadband
- Extension of the ANT Work Plan to Operation and Maintenance related
Standards activities, Standards activities related to security and
protection mechanisms and higher Layers up to Layer 3 (e.g. IP-related Layer
3 functionality)
- Tasks
Tasks include, but are not limited to:
- Update the ANT Standardization Overview (ongoing)
- Update the ANT Standardization Work Plan (ongoing)
- Update the ANT web presentation corresponding to the revisions of
the ANT Standardization Overview and Work Plans in order to maintain
easy access to the actual information.
- Respond to specific requests for information on ANT standards from
other standards organizations and other interested entities.
- Contribute to the success of pertinent ITU-T activities
- Communicate with other groups, inside and outside ITU-T as needed
for coordination purposes
