Returning CableCARD Modules to Service
When subscribers cancel their CableCARD module services, you must remove
services from the CableCARD module they return. After you remove these services,
the CableCARD module can no longer view encrypted sources or copy-protected
content.
Important: The following procedures are not required when you remove services
from a CableCARD module returned by a subscriber:

Deleting the CableCARD module from the DNCS database (the DNCS maintains
a record of the CableCARD module in the database).

Modifying the Host Revoked option within the CableCARD module user
interface (this option only defines whether or not the CableCARD module is
bound to a host).

Maintaining the CRL list (the CRL list is provided by CableLabs to identify
devices that should not be authorized in the system).
Removing Services from CableCARD Modules
You must use billing system transactions to remove services from CableCARD
modules.
Note: It is not required to unbind the CableCARD module from the host. However,
if your billing system allows it, you might want to delete the binding from the
CableCARD module as a housekeeping procedure.
Refer to your billing system documentation for instructions and specific information.
