Recommendation ITU-T G.9960
Unified high-speed wireline-based home networking transceivers –
System architecture and physical layer specification
Summary
Recommendation ITU-T G.9960 specifies the system architecture and physical (PHY) layer for
wireline-based home networking transceivers capable of operating over premises wiring including
inside telephone wiring, coaxial cable, and power-line wiring. It complements the data link layer
(DLL) specification in Recommendation ITU-T G.9961.
Besides the inclusion of minor enhancements and error fixes, this version of the Recommendation
removes the control parameters that determine spectral content, power spectral density (PSD) mask
requirements, and the set of tools to support reduction of the transmit PSD, all of which have been
moved to Recommendation ITU-T G.9964.
This edition of ITU-T G.9960 includes the changes introduced by Erratum 1 (07/2012) and
Erratum 2 (09/2012).

FOREWORD
The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of
telecommunications, information and communication technologies (ICTs). The ITU Telecommunication
Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical,
operating and tariff questions and issuing Recommendations on them with a view to standardizing
telecommunications on a worldwide basis.
The World Telecommunication Standardization Assembly (WTSA), which meets every four years,
establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on
these topics.
The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1.
In some areas of information technology which fall within ITU-T's purview, the necessary standards are
prepared on a collaborative basis with ISO and IEC.
NOTE
In this Recommendation, the expression "Administration" is used for conciseness to indicate both a
telecommunication administration and a recognized operating agency.
Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain
mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the
Recommendation is achieved when all of these mandatory provisions are met. The words "shall" or some
other obligatory language such as "must" and the negative equivalents are used to express requirements. The
use of such words does not suggest that compliance with the Recommendation is required of any party.
INTELLECTUAL PROPERTY RIGHTS
ITU draws attention to the possibility that the practice or implementation of this Recommendation may
involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence,
validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others
outside of the Recommendation development process.
As of the date of approval of this Recommendation, ITU had received notice of intellectual property,
protected by patents, which may be required to implement this Recommendation. However, implementers
are cautioned that this may not represent the latest information and are therefore strongly urged to consult the
TSB patent database at http://www.itu.int/ITU-T/ipr/.
