Cisco Cisco Broadband Access Center for Cable 4.0 Release Notes

BAC provides provisioning and managing of residential devices, namely DOCSIS cable modems and 
set-top boxes (STBs), PacketCable embedded MTAs (eMTAs), CableHome devices, and computers.

This release of BAC supports provisioning and managing:

DOCSIS 2.0 IPv4 and IPv6 devices (booted using the IPv4 or IPv6 provisioning flow or dual stack).

IPv6 devices, including cable modems compliant with DOCSIS 3.0, computers, and set-top boxes 
(STBs).

Video STBs, specifically the RNG-200 STB for IPv4 and IPv6 that is based on the evolving 
OpenCable Application Platform.

Variants of eSAFE (embedded Service/Application Functional Entities) devices, such as mixed-IP 
mode PacketCable MTAs. A mixed-IP mode MTA is an eSAFE device that consists of an IPv6 
embedded cable modem and an IPv4 eMTA. This class of devices embeds additional functionality 
with cable modems, such as packet-telephony, home networking, and video.

As in previous releases, BAC continues to provision:

Cable modems and STBs compliant with DOCSIS 1.0, 1.1, and 2.0.

eMTAs compliant with PacketCable version 1.5

Devices compliant with CableHome 1.0.

Computers.
