The serial number is formatted as PKxxxxxxx, where xxxxxxx represents a BASE-20
number starting at BBBBBBB. The MAC address takes the traditional UNIX syntax
for a printed Ethernet address (aa:bb:cc:dd:ee:ff) where a through f are hexadecimal
digits. All ASCII strings are NULL (0x0) terminated.
The Type_Type, Type_Rev, and Type_Oui fields communicate the type of device
The Type_Type, Type_Rev, and Type_Oui fields communicate the type of device
included in the shipment (SSC DHCTs excluded). These fields use the same values
as those supplied in a BOSS DhctType descriptor. The OUI field is three binary bytes
rather than a set of ASCII characters.
dncs Directory
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 Tuning Adapter 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 device records. Each file contains the records for one
Tuning Adapter, and each record corresponds exactly with the Tuning Adapters
represented in the /toc file.
/dncs/hcttypes contains the Type definitions for all Tuning Adapters in the
shipment. When the DNCS installs a batch of Tuning Adapters, 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 Tuning Adapter,
and each record corresponds exactly with the Tuning Adapters represented in
the /toc file.
/dncs/bootpgs contains bootterm pages.
Note: The DNCS uses the files in the /dncs directory to register devices in the
network, which must be performed before these devices can be authorized to receive
secure services. These files are typically not used by billing systems.
Inventory File
The inventory file (/inventry) is not used by the Tuning Adapter, but it is included
with the files required for a shipment of Tuning Adapters. This file will not affect the
staging of Tuning Adapters.
