Add a PCG 
Introduction 
After you add an MPEG source, if you are using a third-party Event Information 
Scheduler (EIS) and a third-party scrambler (on a third-party SCS) for scrambling the 
stream, you must add the PowerKEY Conditional Access Gateway (PCG) to the 
DNCS database. The PCG is responsible for generating the entitlement control 
messages (ECMs) for a given service. The PCG receives the program data and the 
Control Word (CW) with which it generates the ECMs. The PCG does that with a 
skeleton ECM received from the DNCS. The SCS is responsible for encrypting the 
transport stream with the given CW and inserting the ECMs into the stream.  
The PCG needs one interface to communicate with the SCS on a private network, 
and it needs another interface to communicate with the DNCS. 
 
Before You Begin 
Before you begin, you must have your network map and the PCG provisioning 
parameters. If you cannot locate your network map, refer to Customer Support (on 
page 190). You must also have the following information: 
 
Name used to identify the PCG 
 
NIC-IP address on the PCG to communicate with the DNCS (from your system 
administrator) 
 
MAC address for the above interface on the PCG (from your system 
administrator) 
 
Subnet mask for the above interface on the PCG (from your system 
administrator) 
 
Gateway IP for the above interface on the PCG (from your system administrator) 
 
NIC-IP address on the PCG to communicate with the associated SCS(s) on a 
private network (from your system administrator)  
 
Subnet mask for the above interface on the PCG (from your system 
administrator) 
 
Gateway IP for the above interface on the PCG (from your system administrator) 
 
Maximum PCG session count 
 
ID given for the PCG device 
 
The timeout (in seconds) for the communication from the DNCS to the PCG 
 
The configuration file that needs to be sent to the PCG from the DNCS
