general
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 display 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 SAT IF input signal quality based on
their colour and indicate if the respective channel strip is switched on (LED
illuminates) or off. Additionally the quality of the transport stream received is
displayed ("CN…"). The integrated TPS module (Transport Stream Processing)
processes the data of the transport streams.
The COFDM modulated RF output signals are sent through the RF output of the
cassette to the 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 version of the control unit must be "V 44" or higher. You can find the current operating software for the control unit and the cassette, the software "BE-Flash"
and the current assembly instructions on the website "www.gss.de/en".
The cassette is intended for use in the
STANDARD LINE
head-end stations.
2.5 soft ware q u ery
Control unit
If necessary, you can activate the indication of the software version of the
control unit manually:
• Press any two keys on the control unit of the head-end station simultaneously
until the display goes dark and the software version, e.g. "V 44" appears.
Cassette
After activating the cassette the software version of the cassette is displayed
(see page 20).

2.6 how the tPs mod ule wo r ks
After decoding QPSK- or 8PSK-modulated signals, the demodulated data
streams and the data stream fed via the ASI socket can be accessed via the
integrated TPS module. These data streams, also called transport streams,
contain several stations in all their components (video, audio, data and service
information), which can be changed using the TPS module.
stati on filter
Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output symbol rate. Additionally stations of the different transport
streams can be assembled to a new transport stream.
stuf f i ng
The transport stream is padded using what is known as zero data. This ensures
a steady and constant output data rate.
Changi ng the trans Port s t ream a nd orgnet-id
The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of the channel strips "A" and "B", one of the
both transport streams a new identification must be allocated to realise the
channel search of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.
Changi ng the nit
The transport stream contains data in the form of tables which the receiv-
ers evaluate and require for convenient use. The TPS module can adjust the
"Network Information Table" (NIT) to accommodate the new station data. The
"NIT" contains data which is required by the set-top boxes connected to the
cable network for the automatic search feature.
Changi ng the o Perat o r id (Cat)
Some network operators transmit an operator ID in the data stream (e.g.
visAvision). By changing the CAT the operator ID can be adjusted to the current demands.

3.1 installi ng the C assette
– Ensure the head-end station is mounted so it will not be able to vibrate.
Avoid, for example, mounting the head-end station onto a lift shaft or any
other wall or floor construction that vibrates in a similar way.
– Before installing or changing a cassette unplug the power cable from the
mains power socket.
• Remove the fastening screws 1 of an unoccupied slot from the bracket of
the head-end station.
• Insert the cassette in this slot and push it into the housing.
• Align the cassette and apply slight pressure to connect it to the connections
of the board and the RF bus bar.
• Fasten the cassette with the screws 1.

3.2 emC regulations
To comply with the current EMC regulations, it is necessary to connect the lines
leading in and out of the head-end station using cable terminals.
When mounting the cassette in a head-end station which is installed in a 19"
cabinet, make sure the connections leading in and out for the 19" cabinet are
made using cable terminals.
The attenuation of shielding of the connection lines for ASI and antenna must

meet the requirements for "Class A".
• Insert the required number of cable terminals in the openings provided in
the head-end station or in the 19" cabinet.
Tighten the nuts on the cable terminals until the teeth on the lock washer have
penetrated the exterior coating and a good connection is made between the housing and cable terminals.

3.5 retr o fitting a Ca module
The cassette is equipped with a common interface. It allows you to connect a
CA module for various scrambling systems and service providers. Scrambled
channels can only be descrambled with a CA module suitable for the scrambling system and the corresponding smart card. The smart card contains all
the information for authorisation, descrambling and subscription.
Caution
– Check with the distributor or manufacturer of the CA module to be used
to ensure that it is suitable for decoding several channels.
– The hardware and software of this cassette have been thoroughly prepared
and tested.
– Any changes made by programme provider to the structures in the pro-
gramme data might impair or even prevent this function.
– When working with the CA module, please read the corresponding operat-
ing manual from the respective provider.
• Insert the smart card into the CA module so that the chip 3 on the smart
card 1 faces the thicker side (top) of the CA module 2.
• Insert the CA module into the slot 4 with the top side of the CA module
facing the RS-232 socket of the cassette.
• Push the CA module without canting into the guide rails of the CA slot 4
and contact it to the common interface.

output level using the appropriate level controls or software dependent on
the head-end station used. Please regard the assembly instructions of the
respective head-end station.
