6.3.2.4 Setting up a BISS Descrambler
To descramble an outgoing stream with the defined BISS key, select the appropriate descrambler card and key
to be used in the output service configuration page. If using a Bulk Descrambler module, ensure that it is running
in DVB-CSA mode (BISS not available for AES Bulk Descrambler). If that is the case, the “Descrambler” drop-
down menu in the output settings of an outgoing stream will presented a “BISS” option, that shall be selected.
Then choose the corresponding fixed-key in the “Control Word” drop-down menu and click “Apply” to start BISS
or BISS2 descrambling.
