respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://ipr.etsi.org).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

1 Scope
The present document describes a method for distributed deployment and centralized control of a DOCSIS cable
broadband access system in which the cable network equipment is used in a plant where fibre is run to the cabinet
(e.g. in the basement of a customer's multiple dwelling unit) and coax to each customer. This architecture is collectively
referred to as Cabinet DOCSIS or "C-DOCSIS". It has been developed to meet the operability and manageability
requirements for cable networks that offer a variety of high-bandwidth services and provide QoS guarantees for these
services in a distributed architecture. This architecture applies to the operations, administration and management
(OAM) of cable broadband access networks.
The present document defines optional implementation architectures for CMTS equipment intended for use in
distributed deployments. It defines the functional modules within the CMTS, three different system architectures
utilizing the functional modules and the data and control interfaces between these modules for each of those
architectures. It also defines general device requirements for the different distributed CMTS architectures.
The present document corresponds to the CableLabs C-DOCSIS specification [i.4].

1 Scope
The present document describes a method for distributed deployment and centralized control of a DOCSIS cable
broadband access system in which the cable network equipment is used in a plant where fibre is run to the cabinet (e.g.
in the basement of a customer's multiple dwelling unit) and coax to each customer. This architecture is collectively
referred to as Cabinet DOCSIS or "C-DOCSIS". It has been developed to meet the operability and manageability
requirements for cable networks that offer a variety of high-bandwidth services and provide QoS guarantees for these
services in a distributed architecture. This architecture applies to the operations, administration and management
(OAM) of cable broadband access networks.
The present document defines optional implementation architectures for CMTS equipment intended for use in
distributed deployments. It defines the functional modules within the CMTS, three different system architectures
utilizing the functional modules and the data and control interfaces between these modules for each of those
architectures. It also defines general device requirements for the different distributed CMTS architectures.
The present document corresponds to the CableLabs C-DOCSIS specification [i.4].
