The records for the DHCTs and the CableCARD modules are contained in the
/dncs/dhcts directory. Each file contains the records for one DHCT or one
CableCARD module, and each record corresponds exactly with the DHCTs and the
CableCARD modules represented in the /toc file.
hcttypes Directory
The /dncs/hcttypes directory contains the Type definitions for all DHCTs and
The /dncs/hcttypes directory contains the Type definitions for all DHCTs and
CableCARD modules in the shipment. When the DNCS installs a batch of DHCTs or
CableCARD modules, it first checks for the prior installation of the types listed in the
/dncs/hcttypes directory. Then, the DNCS only installs the types listed in the
directory that have not been previously installed. Each file in this directory contains
the records for one DHCT or one CableCARD module, and each record corresponds
exactly with the DHCTs and the CableCARD modules represented in the /toc file.
bootpgs Directory
The records in the /dncs/bootpgs directory contain the following C structure:
The records in the /dncs/bootpgs directory contain the following C structure:
struct bootPg {
char PageName[81];
char skipped[3];
// pad to 4-byte boundary
unsigned int length;
// number of content bytes to follow
unsigned char content[0];
}
The PageName is the name the DNCS uses to register the page. The length indicates
the number of bytes of page content; the page content bytes follow the length field.

Management Message (EMM) data onto the DNCS. EMMs are encrypted packets of
information that carry default PowerKEY information and service authorizations for
DHCTs and CableCARD modules. EMMs let the devices use secure services.
Important: When you load the EMM files, make sure that you do not provision any
Important: When you load the EMM files, make sure that you do not provision any
DHCTs. Enabling any options on the Secure Services tab in the Set Up DHCT screen
causes the DNCS to provision the DHCTs.
If you do provision DHCTs when you load EMMs, combo binding will not work
If you do provision DHCTs when you load EMMs, combo binding will not work
