ANSI SCTE 140:2019 pdf download.Cable Modem IPv4 and IPv6 eRouter Specification.
ANSI SCTE 140 was developed for the benefit of the cable industry, and includes contributions by operators and vendors from North America, Europe, and other regions.
The present document corresponds to and is the technical equivalent of the CableLabs (eRouterl specification.
1.1 Introduction and Purpose
ANSI SCTE 140 defines a core set of features that enable multiple subscriber devices to gain access to operator provided high-speed data service using DOCSIS. This core set of features allows for both IPv4- and IPv6-enahled devices to gain connectivity to the Internet.
The eRouter is specified as an Embedded Service/Application Functional Entity (eSAFE) device as defined in [eDOCSIS] that is implemented in conjunction with an embedded DOCSIS cable modem device.
The core set of features defined in this specification includes the ability to provision multiple CPE devices, a description of how to forward data to and from CPE devices, and also the ability to forward IP Multicast traffic to and among CPE devices.
