SIST ES 203 311-2 V1.1.1:2020
(Main)The present document provides the ETSI endorsement of ANSI/SCTE Standard 220-1 [1].
ANSI/SCTE Standard 220-1 is part of a series of specifications that defines the fourth generation of high-speed dataover-
cable systems, commonly referred to as the DOCSIS 3.1 specifications. The standard was developed for the
benefit of the cable industry, and includes contributions by operators and vendors from North and South America,
Europe and Asia.
This generation of the DOCSIS specifications builds upon the previous generations of DOCSIS specifications
(commonly referred to as the DOCSIS 3.0 and earlier specifications), leveraging the existing Media Access Control
(MAC) and Physical (PHY) layers, but with the addition of a new PHY layer designed to improve spectral efficiency
and provide better scaling for larger bandwidths (and appropriate updates to the MAC and management layers to
support the new PHY layer). It includes backward compatibility for the existing PHY layers in order to enable a
seamless migration to the new technology.
There are differences in the cable spectrum planning practices adopted for different networks in the world. For the new
PHY layer defined in the present document, there is flexibility to deploy the technology in any spectrum plan; therefore,
no special accommodation for different regions of the world is specified for this new PHY layer.
However, due to the inclusion of the DOCSIS 3.0 PHY layers for backward compatibility purposes, there is still a need
for different region-specific physical layer technologies. Therefore, three options for physical layer technologies are
included in the present document. One technology option is based on the downstream channel identification plan that is
deployed in North America using 6 MHz spacing. The second technology option is based on the corresponding
European multi-program television distribution. The third technology option is based on the corresponding Chinese
multi-program television distribution. All three options have the same status, notwithstanding that the document
structure does not reflect this equal priority. The first of these options is defined in clauses 5 and 6 of [1], whereas the
second is defined by replacing the content of those clauses with the content of Annex C of [1]. The third is defined by
replacing the content of those clauses with the content of Annex D of [1]. Correspondingly, [14] and [4] apply only to
the first option, and [5] applies to the second and third. Compliance with the present document means compliance with
one of these implementations, but not with all three. It is not expected that equipment built to one option interoperates
with equipment built to the other.
Compliance with frequency planning and EMC requirements is not covered by the present document and remains the
operators' responsibility. In this respect, [11] and [12] are relevant to the USA; [3] and [i.2] to Canada; [i.4], [6], [7],
[8], [9] and [10] are relevant to the European Union; [13] and [i.1] are relevant to China.
ANSI/SCTE Standard 220-1 defines the interface for the physical layer, and corresponds to the CableLabs
specification [i.3].
