6.1 Descrambling – Common Interface Module
The unit is capable of descrambling a number of incoming services with the installation of a
descrambler module. The descrambler module comes with two Common Interface slots and
can therefore host two Conditional Access Modules (CAM’s). Each Common Interface slot
supports the descrambling of one or more services depending on the CAM module used.
6.1.1 Descrambling a Service
To descramble a service first insert the CAM into an available Common Interface slot, then
insert your Smart Card into the CAM.
To assign the Common Interface slot to a service to be descrambled, double click on that
service and within the Outputs page to display the Service Properties dialog (Figure 6.2).

6.1.2 Transporting a Descrambled Service to Multiple Output Modules/Ports
A descrambled service may be sent to up to four individual outputs. In other words, if the unit is
configured with an IP output module and a QAM output module, then the descrambler module
will be able to copy the descrambled service and send it to both the IP output and QAM output
destinations. Alternatively, the same service can be sent to different ports on the same output
module.
When an input service is configured to be sent to different outputs, the configuration is
automatically performed by the system – as long as the same descrambler is selected. This
copy function is based on per service, i.e. if a Smart Card is able to descramble up to 10
services, then the maximum number of output streams from the descrambler will be 40 (10 x
4).
