Delivering ECMs
Introduction
The system elements descriptions in the PowerKEY Conditional Access System
Overview (on page 3) sectopm and the following ECM delivery process describe
how the PowerKEY ECMs arrive at the set-top.
Overview (on page 3) sectopm and the following ECM delivery process describe
how the PowerKEY ECMs arrive at the set-top.
The process begins with system initialization and proceeds to the DNCS/ISDS and
SCS/Scrambler interactions outlined below:
SCS/Scrambler interactions outlined below:
The PCG is fully configured and provisioned
The DNCS/ISDS creates sessions on the PCG
The SCS establishes a TCP connection, channel, and valid streams on the PCG
The PCG responds with ECM streams for existing sessions/services setup by the
DNCS/ISDS on the PCG

Note: This process assumes that the PCG has been set up. If you need to set up the
PCG, see Install the PCG Software (on page 15).
1 When the PCG powers up, it can be configured manually or using BOOTP. Then
PCG, see Install the PCG Software (on page 15).
1 When the PCG powers up, it can be configured manually or using BOOTP. Then
the eth0 gets its network address and the PCG application is launched.
2 The PCG sends a provision request to the DNCS/ISDS. When the DNCS/ISDS
receives the request, it sends the PCG a provision response. The response
contains data that sets the eth1 network address for communication with the
scrambler device(s).
Optional: The response may inform the PCG about how many such devices can
communicate with the PCG, provide their IP addresses, and indicate how many
programs can be serviced on each device.
Note: The PCG can support a maximum of 1000 sessions.

3 Create a session from the DNCS/ISDS. This provides the access criteria for the
PCG to service.
Note: If you are using ROSA for access criteria management then configure the
EIS/Access Criteria Manager Component (ACMC) through the ROSA element
manager. Ensure the access criteria specified here match the access criteria
