The /dncs directory contains the following directories that include information
needed by the DNCS:
/dncs/cauth contains the key certificates required for Key Certification
Authorities that have certified SSC DHCT public keys. This directory includes
the certificates for all the Certification Authorities that created the certificates
carried in the records in the /dncs/dhcts directory. It might also include
certificates for other Certification Authorities.
/dncs/dhcts contains records for the DHCTs and the CableCARD modules. Each

Note: The dhcts directory does not include information on the paired SSC
DHCTs. That information is contained in the inventory file.
/dncs/hcttypes 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.
/dncs/bootpgs contains bootterm pages.
/dncs/revlist contains the certification revocation list.

secure services. These files are typically not used by billing systems.
