Transmit DHCT Billing Transactions With the IIH Utility
749640 Rev D
Four Billing Transactions
Introduction
Cisco engineers developed the IIH utility to transmit four separate billing
transactions to DHCTs. The system determines which billing transaction you want to
transmit through the specific parameters you use when you run the IIH utility. The
following list contains the four billing transactions, as well as the identifying
parameter(s):
•
•
dhctInstantHit—specified by the –i parameter
•
resetClientNvm—specified by the –r parameter
Note: The –r parameter is only supported by sites that use the Cisco Application
Note: The –r parameter is only supported by sites that use the Cisco Application
Server.
•
bootDhct—specified by the –b parameter
•
setPin—specified by the –bp and -pp parameters
Each transaction is discussed in some detail in the remainder of this section.
dhctInstantHit
The dhctInstantHit transaction refreshes DHCTs with their Entitlement Management
Messages (EMMs).
Note: EMMs are encrypted packets of information that the DNCS uses to supply
Note: EMMs are encrypted packets of information that the DNCS uses to supply
secured service authorizations to DHCTs. EMMs enable DHCTs to use many digital
and interactive broadcast services.
resetClientNvm
The resetClientNvm transaction resets the non-volatile memory (NVM) of a DHCT
to default values established at the factory.
Note: While the resetClientNvm transaction can be run to reset the NVM of DHCTs
Note: While the resetClientNvm transaction can be run to reset the NVM of DHCTs
associated with a specific QPSK modulator or demodulator, the need to use this
application in this manner is unlikely.
