esCriPtion
The twin transmodulator cassette is a converter, which converts signals modu-
lated according to DVB-C/C2/T/T2 standard into two QAM modulated signals
for feeding into a cable network. The cassette has two digital RF inputs and one
RF output.
Two common interfaces are present to descramble scrambled channels.

".
LEDs provide an indication of the input signal quality based on their colour
and indicate if the respective channel strip is switched on (LED illuminates) or
off.
