2.4 desCriPtion
The cassette converts two incoming COFDM -modulated signals into two out-
going COFDM-modulated signals with free selectable frequency . Individual
stations can be deleted. The cassette has two DVB-T inputs and one HF output.
General
The cassette is equipped with two channel strips (" A " and " B "). The channel
stripsconsistoftheDVB-T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". 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. The integrated TPS module (Transport Stream Processing) processes the
data of the transport streams.
The COFDM modulated HF output signals are sent through the HF output of the
cassette to the output collector. The common output level of the channel strips
can be set at the output collector.
 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 43" 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 designed for use in head-end stations of the profi line.

2.6 how the tPs module works
 After decoding COFDM-modulated signals, the demodulated data streams
can be accessed via the integrated TPS module. These data streams, also
calledtransportstreams,containseveralstationsinalltheircomponents(vid-
eo,audio,dataandserviceinformation),whichcanbechangedusingtheTPS
module.

 Individual stations can be deleted. This reduces the data rate and, conse-
quently,theoutputsymbolrate.
stuffing
 Thetransportstreamispaddedusingwhatisknownaszerodata.Thisensures
a steady and constant output data rate.
Changing the tr ansPort stream and 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.
Changing 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.

– 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.

3.2 emC regul ations
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.
CLASS
KLASSE
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 of the cable terminals until the teeth on the lock washers put un-
der have penetrated the exterior coating and a good connection is made between
the housing / 19" cabinet and cable terminals.
