The cassette is equipped with two channel strips (" A " and " B "). The channel
strips consist of the digital tuners, the digital signal preparation units and the
output converter. The channel strips are indicated in the head-end station dis-
play with "
Bx …A " and " Bx …B ". Using an adequate CA module scrambled
channels can be descrambled via channel strip " A ". The control of the cassette
takes place via the control unit of the head-end station.
Two LEDs provide an indication of the input signal quality based on their col-
our and indicate if the respective channel strip is switched on (LED illuminates)
or off. During the boot process both LEDs are blinking.
The integrated TPS module (Transport Stream Processing) processes the data
of the transport streams.
The QAM modulated RF output signals are sent through the RF output of the
cassette to the RF output collector. The common output level of the channel
strips can be set at the output collector. Additionally a transport stream is made
available via the ASI output dependent on the signal path set.
When the head-end station is switched on, the two-line LC display shows the
software version of the control unit. To operate this cassette the software ver-
sion of the control unit must be "
V 44 " or higher. You can find the current op-
erating software for the control unit and the cassette, the software " BE-Flash "
and the current assembly instructions on the website " www.gss.de ".
The cassette is intended for use in the STANDARD LINE head-end stations.
