What Are the New Features in SR 4.3?
SI Application ID for ADSG
This feature allows you to populate the application ID field with an appropriate
downstream channel descriptor (DCD) message.

To enable a tru2way-compatible set-top in the Aspen system to determine the
location of the mini-carousel protocol (MCP) required for switched digital video
(SDV) operation, a special setup must be configured on the DNCS. The location of
the DSG tunnel in which the MCP is spooled must be transmitted on a hidden
channel that each set-top can access.

the DSG tunnel in which the MCP is spooled must be transmitted on a hidden
channel that each set-top can access.
In addition to the MCP, other configuration information is available to the set-top
through this same mechanism. This includes the first 8 hours of electronic program
guide (EPG) data.

This operation is performed by using the new functions present in this system
release to create a special hidden source with a value of 5000 and the service name
TVW_OCAP. This source is then mapped to channel 1899 in the channel lineup
where it is retrieved by the set-top host.

Additional DNCS Network Interface for ADSG Clients
The DNCS uses a single IP address which all of our headend components (such as
QAMs, QPSKs, Netcrypt Bulk Encryptors, and so on) and set-tops recognize for
provisioning.

All real world implementations of the CMTS bridges require delivery on a multicast-
enabled network. However, many DBDS networks currently in the field are not
multicast enabled. Several service providers have expressed the desire to have a
separate DNCS physical interface for their multicast-enabled High Speed Data
Networks which service cable modems.

Networks which service cable modems.
To address this request, the DNCS System Configuration window now includes an
option to select an additional DNCS IP address specified by the name “dncsdsg” to
be used in the DOCSIS path. This option will be provided only if the DOCSIS feature
is enabled. Once selected, this option applies to all CMTS bridges in the system.
