• One handles MPEG-2 video, audio, broadcast control data, and broadcast service data.
• The other supports DOCSIS IP data. The return path is implemented with EuroDOCSIS.
EuroDOCSIS STB Support
Depending on the network configuration, servers that support Internet-enhanced video services—DTV
application servers, user data servers, system management servers—and other tools and applications, are
required to enable cable operators to deliver centrally managed services through STBs.
See the “Automatic Provisioning of Cable Modems” section on page 1-9. APIs need to be set up to allow
EuroDOCSIS servers to communicate with the CSRC directory to obtain such information as IP
addresses, user names, and subscription levels.
After registered subscribers receive a EuroDOCSIS-based STB, they can connect up the STB. Automatic
configuration begins when the CM in the STB is detected and the CSRC DHCP server establishes IP
connectivity and the basic IP configuration. As part of this initialization, the DHCP server transmits to
the client STB, binding information for other resources such as TOD and TFTP servers.
When using this initial configuration, the DOCSIS CM uses TFTP to download its default DOCSIS
configuration file, such as the DOCSIS options associated with the STB vendor subnet and CMTS. When
minimally configured, the STB will register with the Cisco uBR7100 series router and create an
associated object in the LDAP directory. The subscriber can then access the Cisco User Register web
user interface to select one or more of the service packages the cable operator offers.
