SMCIP 401 ASI
2.4 d
esCriPtion
The transmodulator converts channels from up to four DVB-S/DVB-S2 trans-
ponders (four tuners A…D or three tuners A…C and the ASI input) into one
DVB-S transponder.
Using an adequate CA module the scrambled signals contained in this mul-
tiplex (MUX) can be descrambled. The number of signals to be descrambled
depends on the CA module and the smart card.

ASI Output
The four tuners receive their input signal from the outputs of a multiswitch.
In addition it is possible to feed in the ASI input signal instead of the tuner D
signal. The stations selected via the station selection menu will be multiplexed,
if necessary descrambled and modulated as DVB-S transponder.
—> Note the maximum possible output data rate of 72.573 Mbits/s,
which depends on the DVB-S output parameter settings!
If only the ASI output is needed, the modulator can be switched off.
If no further input is free for the converted signal at the multiswitch, the cor-
responding satellite band can be multiplexed via the LNB input with the output
transponder of the GSS.mux and then feed into the multiswitch.
