esCriPtion
The double transmodulator cassette is a converter, which converts all stations
modulated according to DVB-S / DVB-S2 standard into two COFDM-modulated
signals according to DIN EN 300744 for feeding into a cable network. The
cassette has two digital SAT IF inputs and one RF output. Additionally it is
equipped with an ASI input and an ASI output (ASI – Asynchronous Serial
Interface acc. DIN EN 50083-9).
The transport stream fed via the ASI socket can be inserted into the transport
streams of the receiving stages via the TPS module. The signal path is set in the
menu items input signal path "
INROUTE " and output signal path " OUTROUTE ".
