Overview
Staging SSC DHCTs consists of two processes. First, the host DHCT downloads the
required software. Then, the M-Card module paired with the DHCT begins its
download.

These procedures assume that you have followed the recommendations in the
first several chapters of the Explorer Digital Home Communications Terminal
Staging Guide (part number 734375) regarding the staging process, staging
preparations, staging area considerations, obtaining and loading EMM data, and
staging DHCTs and CableCARD modules.
Before staging SSC DHCTs, you must make sure that you do not enable Digital
Interactive Services (DIS) or any other options on the Secure Services tab in the
Set Up DHCT screen. If you do enable these options, you will provision the
DHCTs when you batch load the EMMs, which prevents combo binding from
working correctly and might prevent the DHCTs from properly staging. See
Batch Loading EMM Files and Disabling DIS (on page 11) for more information.
The SSC Staging Process
1 The DHCT downloads its operating system. This occurs immediately when the
DHCT is connected to the network. The software downloaded is specified for
each DHCT model and revision combination. When the download is complete,
the operating system code is written to the flash memory of the DHCT and the
DHCT reboots.
2 The hard disk drive (HDD) of DVR-equipped DHCTs is initialized. After the first
reboot, the DHCT performs HDD initialization. When this initialization is
complete, the DHCT reboots.
Note: This step is only applicable to DHCTs with DVRs, such as the Explorer
Note: This step is only applicable to DHCTs with DVRs, such as the Explorer
8300 series.
3 The inserted CableCARD module downloads its operating system. This occurs
after a delay while the CableCARD module hunts for and identifies the correct
download frequency. When the download is complete, the operating system
code is written to the flash memory of the CableCARD module and the DHCT
reboots.
4 The staging area sends a ModifyDhctConfig message through the billing system
to the DNCS. The DNCS sends out the EMMs. The CableCARD downloads its
EMMs.
5 The ModifyDhctConfig message also initiates the DNCS to place a bindAuth
record on the BFS carousel. When the DHCT receives the message the binding
process occurs.
