Introduction
This European Standard (Cable DOCSIS 3.0 Network series) has been produced by ETSI Access, Terminals,
Transmission and Multiplexing Technical Committee (ATTM), Cable Access Network sub-group.
The present document is part 2 of a multi-part deliverable covering Third Generation Transmission Systems for

1 Scope
The present document defines the physical layer requirements as part of a series of specifications for the third
generation of high-speed Data-Over-Cable Systems Interface Specifications (DOCSIS®).
They were developed for the benefit of the cable industry, including contributions by operators and vendors from,
Europe, North America and other regions.
The source material for the present document was provided by the ITU-T Recommendation J.222.1 [5] for which the
most recent version can be found at http://www.itu.int/ITU-T/.
There are differences in the cable spectrum planning practices adopted for different networks in the world. Therefore
two definitions for physical layer technology are included, which have equal priority and are not required to be
interoperable. One technology definition is based on the downstream multi-programme television distribution that is
deployed using 8 MHz channelling, and supports upstream transmission in the 5 MHz to 65 MHz region. The second
technology definition is based on a multi-programme television distribution using 6 MHz channel spacing and supports
upstream in the 5 MHz to 42 MHz region. Both options have equal status.
The choices of physical-layer technologies allow operators some flexibility within any frequency planning, EMC and
safety requirements that are mandated for their area of operation.
EXAMPLE: The 6 MHz downstream-based option might be deployable within an 8 MHz channel plan. It is the
network operator's choice of which technology definition to deploy.
NOTE: The current document references both physical layer technologies and where there are parameter
differences both are specified for both options:
i) 8 MHz channel spacing; and.
ii) 6 MHz channel spacing.
All optional physical-layer technologies are required to be backwards compatible with the earlier versions of those
options defined in ES 201 488 [i.4] and ES 202 488 [i.5].
Requirements for EMC and safety are outside the scope of the present document. EMC and safety standards for
European applications are published by CENELEC.
NOTE 1: Examples of such CENELEC product safety standards are EN 60950 [i.6] and EN 50083-1 [i.6].
NOTE 2: For CENELEC safety categories of interfaces, see EG 201 212 [i.2].
NOTE 3: Examples of such CENELEC product EMC standards are EN 50081-1 [i.7], EN 50082-1 [i.8] and
EN 50083-2 [i.3].
