The operating software of the Cassette can be actualised via the 9-pin SUB-D- socket, using a PC or notebook (software “BE-Flash”). You can find the current operating software of the Cassettes on the website “www.triax.com”. The prepared input signals are transmitted to the HF output collector of the head- end station via the HF output socket. -

Page 7: Explanation Of The Term "Symbol Rate
2.3.3 Explanation of the term “symbol rate” Modulation schemes such as QPSK and QAM transmit multiple bits simultane- ously. These are referred to as symbols. In addition to the user data flow which transmits video and audio information, error correction bits are transferred. The FEC number states the ratio of error correction bits to user bits. -
Page 8: Bandwidth-Efficient Assignment Of Cable Channels With Low Bandwidths (Selecplex ® )
2.3.4 Bandwidth-efficient assignment of cable channels with low bandwidths (SelecPlex ® Channels with low bandwidths are the result of filtering out stations which are not required. These “narrow” channels can then be arranged in one channel to save space. To do this, activate fine tuning in the “Output channel” menu (as- signment outside the official channel raster). -
