2.3 Description  
The Cassettes convert two QPSK-modulated data flows into one QAM-modu-  
lated data flow. The Cassettes are controlled via the head end. Each Cassette  
has two inputs and one HF output, as well as an integrated multi-transport flow  
processor for stuffing, PID pass, drop and service filtering.  
For these Cassettes, information from a barker channel can be added or ex-  
changed with a transport flow (MTP function, Drop- and service filter). For this  
purpose, there are two autonomous reception tuners and one modulator on  
which the modified transport flow can be transmitted as a QAM-modulated  
signal.  
The SDT and PAT tables are automatically generated. All data relevant to the  
operation of the Cassette is registered in a logbook with a maximum of 500  
entries.  
The operating software of the Cassette can be actualised via an external 9-pin  
SUB-D-socket, using a PC or notebook, (software “BE-Flash”) or settings in the  
channel strips “A” (service channel) and “B” (barker channel) of the Cassette  
(PC software “MTP, component of software PSW 1000). You can find the cur-  
rent operating software of the Cassettes on the website “http://www.gss.tv.  
The prepared input signals are transmitted to the HF output collector of the head  
end via the HF output socket. The output level of the Cassettes can be set with the  
level regulator (max. –20 dB) at the output collector of the head end.  
After the head end has been switched on, the software version of the control  
unit is displayed briefly in the two-line LC display and afterwards the type of  
Cassette of the first slot.  
Approximately five minutes after the last button has been pressed, the software  
version of the control unit is displayed.  
The Cassettes are designed for use in the following head ends:  
PSU 12  
PSU 8  
PGT 8

2.3.1 Manual display of the software version  
If necessary, you can call up the display of the software version of the control  
unit manually:  
• Hold down any two keys of the control unit simultaneously until the display  
goes dark and the software version, e.g. “V.34”, is displayed.  
2.3.2 How the TP module works  
When converting the QPSK-modulated signal to a QAM-modulated cable signal,  
the demodulated data stream can be accessed via the integrated TP module. This  
data stream, also called transport stream, contains several stations with all their  
components (video, audio, data and service information), which can be changed  
using the TP module.  
The individual functions  
Station filter  
Individual stations can be deleted. This reduces the data rate and, consequently,  
the output symbol rate.  
Stuffing  
The transport stream is padded out using what is known as zero data. This  
increases the data rate and, consequently, the output symbol rate. Changing  
the output symbol rate suitably alters the bandwidth used (halving the output  
symbol rate roughly halves the bandwidth at the output).  
Changing service information  
The transport stream contains data in the form of tables which the receivers eval-  
uate and require for convenient use. The TP module can change the “Network  
Information Table” (NIT). The NIT contains data which the set-top box needs for  
the automatic search function.

2.3.3 Explanation of the term “symbol rate”  
High-quality modulation methods like QPSK and QAM can encrypt several  
bits as a single transferred and received symbol. The user data stream contains  
the audio and video signals of a station and is thus permanently assigned. If  
the value of the modulation and therefore the number of bits per symbol is in-  
creased, the symbol rate falls compared to the user bit rate.  
Formulae for calculating the output symbol rate “SR (A)” at a fixed input symbol  
rate “SR (E)” and “FEC.  
256-QAM:  
128-QAM:  
64-QAM:  
32-QAM:  
16-QAM:  
4-QAM:  
SR (A) = FEC x 1/4 x SR (E)  
SR (A) = FEC x 2/7 x SR (E)  
SR (A) = FEC x 1/3 x SR (E)  
SR (A) = FEC x 2/5 x SR (E)  
SR (A) = FEC x 1/2 x SR (E)  
SR (A) = FEC x 1/1 x SR (E)  
Example:  
Output symbol rate 64-QAM, FEC= 3/4,  
Input symbol rate SR (E) = 27,500 kilosymbols per second  
SR (A) = 3/4 x 1/3 x 27,500 kilosymbols/s  
SR (A)  
=
6,875 kilosymbols/s  
Note:  
If no “FEC” is stated in the station lists, it can be assumed to be  
“FEC = 3  
4.  
/
Reception from a transponder with a very low symbol rate  
(SCPC station)  
The extremely low data rate means that the output symbol rate is very low. If  
there are reception problems with different digital receivers, set QAM modula-  
tion with stuffing to a higher value.  
Defined symbol rates  
Some cable operators specify a fixed symbol rate (e.g. 6,900 kilosymbols per  
second).

3.1 Installing the Cassette  
Warning  
Before inserting or changing Cassettes, pull the mains plug of the head end  
out of the mains socket.  
Unscrew the fastening screws from the bracket in the head end.  
• Insert the Cassette into a free slot and push it into the housing.  
• Align the Cassette and gently make it contact with the connections of the  
circuit board and the HF bus bar.  
• Fasten the Cassette with the 1 screws.

Note:  
The operating software of the Cassette can be updated via the socket  
“RS 232” 3 (9-Pin-Sub-D) by means of a PC or notebook.  
Use the “BE-Flash” software as the update software. You can make drop  
and pass filter settings in the channel strip “B” using the “MTP” PC software.  
You can find the current operating software of the Cassettes on the website  
http://www.gss.tv”.

Programming  
The following examples show how the PHDQ 4002 BC Cassette is programmed;  
the output channels can be set from S21 … S41. Set the other Cassettes listed  
in the same way.  
5.1 Preparation  
Notes:  
Using the menu LEVEL CONTROLthe Cassette generates an equally powerful  
HF carrier on the video carrier frequency of the channel. In this way, the Cas-  
sette‘s level can also be set with an analogue TV test receiver set to the video  
carrier frequency of the channel. In order to prevent interference within the  
head end and the cable system, the output level of the digital Cassettes must  
be lowered by approx. 10 dB at 64 QAM and by approx. 4 dB at 256 QAM  
compared to analogue Cassettes.  
• Connect the test receiver to the “TEST OUTPUT1 of the  
head end.  
• Set the output channel of the Cassette (see page 14) and  
adjust the TV test receiver to this channel.  
• Switch on the modulator if necessary.  
1
• Measure the output level of the analogue Cassettes and, if  
necessary, tune them to a uniform output level.  
Check the output level of the digital DVB-MTP Cassettes.  
Lower the output level of the appropriate Cassette in re-  
lation to the analogue Cassettes at 64 QAM by approx.  
10 dB and at 256 QAM by approx. 4 dB with the level  
adjuster to the right of the Cassette.  
.
After programming the Cassette check the output level of  
the Cassette again and if necessary set it again.

112.0000 MHz  
Modulator:  
+
The QAM signal is transmitted with a bandwidth of 8 MHz.  
This means that you can only use the channel centre fre-  
quency of the existing channel raster in the range of chan-  
nels S21 … C69 (frequency raster 8 MHz). The frequency  
raster is 7 MHz in the range of the lower channel ranges  
(channel S20). If one uses the existing channel raster here,  
this will result in interference (overlapping) of the 8 MHz  
QAM signal packages and thus transmission problems.  
For programming in this channel range, we recommend to  
calculate the output frequency of the QAM modulator,  
starting with the upper output frequency of the Cas-  
sette listed in the “Specifications” going back in steps  
of 8 MHz, or  
starting with the lower output frequency of the Cas-  
sette listed in the “Specifications” moving up in steps  
of 8 MHz.

Setting the DVB mode  
The Cassettes recognize the transmitted DVB mode and  
switch over between the normal QPSK mode (DVB-S) and  
the DVB-S2 mode. Receiving stations with DVB-S2 mode,  
we suggest to preset the DVB mode to shorten the time for  
searching stations.  
Use the  
button to place the cursor under “DVB-S” /  
DVB-S2“ and set the DVB mode with the buttons  
(s. Technical data).  
• Press the  
button.

Setting the input frequency (transponder frequency)  
Notes:  
If three dots “ ” appear in the second line of the display,  
the Cassette is in the “station search” mode.  
Please wait until the process has finished.  
Once the HF receiver has synchronised to the input signal,  
any offset to the target frequency is displayed in MHz, e.g.  
– 0.4.  
– If a question mark “?” appears in the second line of the  
display, there is no input signal present. Check the configu-  
ration of the antenna system and head end as well as the  
preceding settings of the Cassette in question.
