General Information
- Abstract
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].

Overview
SIST ES 203 311-2 V1.1.1:2020 provides the ETSI endorsement of ANSI/SCTE 220-1, a crucial industry standard for integrated broadband cable telecommunication networks, specifically focusing on the physical layer of IP cable modems in DOCSIS® 3.1 networks. This standard defines requirements for the fourth generation of high-speed data-over-cable systems supporting interactive cable television services. It represents significant progress in cable broadband transmission, aiming to deliver greater bandwidth, improved spectral efficiency, and flexibility in deployment across global cable systems.
DOCSIS 3.1 is essential for operators and equipment vendors seeking to upgrade or maintain compatibility with advanced interactive TV and broadband services. By standardizing the physical layer requirements, the document ensures interoperability and promotes seamless migration from DOCSIS 3.0 to newer architectures.
Key Topics
- Physical Layer Specification: Defines requirements for the physical (PHY) layer of DOCSIS 3.1 cable modem systems, supporting high-speed and reliable data transmission over cable networks.
- Backward Compatibility: Includes provisions to maintain compatibility with legacy DOCSIS 3.0 physical layers, minimizing disruption and allowing gradual technology transition.
- Global Application: Addresses different regional cable spectrum planning practices with three equivalent PHY technology options:
- North American downstream channel identification (6 MHz spacing)
- European multi-program television distribution
- Chinese multi-program television distribution
- Deployment Flexibility: The new PHY layer can be deployed with any regional spectrum plan, making it adaptable for operators worldwide.
- Interface Consistency: Aligns with CableLabs specifications, facilitating equipment conformity and industry-wide interoperability.
- Spectrum and EMC Compliance: While the standard focuses on physical layer requirements, compliance with frequency planning and electromagnetic compatibility (EMC) remains the responsibility of network operators.
Applications
SIST ES 203 311-2 V1.1.1:2020 is a key reference for:
- Cable Operators: Enables network providers to deploy or upgrade their infrastructures to DOCSIS 3.1, delivering faster broadband speeds and advanced service capabilities to customers.
- Equipment Vendors: Provides essential requirements for manufacturing interoperable cable modems and related infrastructure that comply with international DOCSIS 3.1 specifications.
- Systems Integrators & Installers: Guides the integration of fourth generation IP cable modems and transmission systems within diverse cable network architectures.
- Standardization Bodies: Acts as a harmonized reference supporting regional and international standardization efforts in broadband cable technologies.
- Regulatory Compliance: Assists in aligning cable television systems with relevant European, American, and Chinese regulatory requirements for physical layer and electromagnetic compatibility.
By adhering to this standard, stakeholders in the cable broadband ecosystem ensure high performance, reliability, and scalability of interactive cable television and broadband services.
