DOCSIS Set-Top Gateway and Advanced-mode 

DSG for the Cisco CMTS

This document describes the DOCSIS Set-Top Gateway (DSG) feature with its configuration and 

monitoring, from DSG Issue 0.9 through Advanced-mode DSG Issue 1.1 on the Cisco Cable Modem 

Termination System (CMTS). This document revision emphasizes DSG Issue 1.0 commencing with 

Cisco IOS Release 12.3(9a)BC, and A-DGS 1.1 commencing with Cisco IOS release 12.3(13)BC.

DSG is a CableLabs

®

 specification that allows cable headend equipment such as the Cisco CMTS to 

provide a class of cable services known as out-of-band (OOB) messaging. OOD messaging is sent to 

set-top boxes (STBs) over existing Data-over-Cable Service Interface Specifications (DOCSIS) cable 

networks. 

DSG 1.0 and A-DSG 1.1 allow cable Multiple System Operators (MSOs) and other service providers to 

combine both DOCSIS and Set-top Box (STB) operations over a single, open and vendor-independent 

network without requiring any changes to the existing DOCSIS network infrastructure.
