Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Integrated broadband cable
telecommunication networks (CABLE).
The present document is part 1 of a multi-part deliverable covering the Fourth Generation Transmission Systems for
Interactive Cable Television Services - IP Cable Modems, as identified below:
®
Part 1: "General; DOCSIS 3.1";
®
Part 2: "Physical Layer; DOCSIS 3.1";
®
Part 3: "MAC and Upper Layer Protocols Interface; DOCSIS 3.1".
®
This multi-part deliverable is based on the CableLabs DOCSIS set of specifications which are also standardized in the
United States by SCTE. Table 1 indicates for the specifications in this multi-part deliverable the equivalent CableLabs
®
DOCSIS specifications and SCTE Standards.

1 Scope
The present document is part 1 of a multi-part deliverable that define the fourth generation of high-speed data-over-
®
cable systems, commonly referred to as the DOCSIS 3.1 specifications. This specification 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.
