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:
