2.4 des Cription

The Head-end Digital Transmodulator QAM
called QAM module converts four DVB-S/DVB-S2 four DVB-C (
QAM)
modulated data streams.
"CGS-2 764 C"
, in the following
modulated data streams into
The
QAM module
has two SAT-IF
inputs and one RF output.
The
QAM
module is equipped with four channel strips ("A" … "D"). The chan­nel strips consist of the digital SAT tuners, the digital signal processing levels and an output converter. For channel strips A/B resp. C/D adjacent channel setting is fixed.
Using adequate CA modules scrambled channels can be descrambled via
channel strips "A" and "C". The control of the module takes place via the con­trol unit of the
head-end station.
Four LEDs indicate if the respective channel strip is switched on (LED illumi-
nates) or off, and also provide an indication of the signal quality based on their colour.
The integrated TPS module (Transport Stream Processing) processes the data
from the demodulated transport streams.
Channel as well as frequency setting is possible for modulators "A" and "C".
The modulators "B" and "D" work at a spacing of + 8 MHz to modulators"A" and "C". Herein only frequency setting (frequency spacing of channel strips "A <–> B" and "C <–> D") is possible to reduce the bandwidth at signals of low data rates.
The QAM modulated RF output signals are sent through the RF output of the
QAM module
to the output collector.
When the head-end station is switched on, the two-line LC display shows the
"SETUP" menu and the software version of the control unit. The head-end sta­tion output level can be adjusted in this menu.
To operate the
station) must be "V 10" or higher. The operating software of the and the
QAM module

QAM module
head-end station can be updated using a PC or notebook and the software "BE-Flash" via the 9-pin D-SUB socket on the head-end station. You can find the current operating software for the head-end station module,
the software "BE-Flash"
and the current assembly instructions
and the QAM
on the
website "www.triax.com".
The
QAM module
is designed exclusively for use in the CSE 2800 head-end
station.

2.5 how the tps module w o rks

After decoding QPSK- or 8PSK-modulated signals, the demodulated data
streams can be accessed via the integrated TPS module. These data streams, also called transport streams, contain several stations with all their compo­nents (video, audio, data and service information), which can be changed using the TPS module.

station fi lte r

Individual stations can be deleted. This reduces the data rate and, conse-
quently, the output data rate.

Ch a n ging the tr ansport s t ream and orgnet-id

The transport stream ID can be changed. If the stations of a transponder are
split into the transport streams of different channel strips, a new identification must be allocated to the "new" transport streams to realise the channel search of the settop boxes connected without mistakes.
If the ORGNET-ID is changed a new NIT must be generated.

Ch a n ging the nit

The transport stream contains data in the form of tables which the receivers
evaluate and require for convenient use. The TPS module can adjust the "Net­work Information Table" (NIT) to accommodate the new stations output data (incl. LCN). The "NIT" contains data which is required by the set-top boxes connected to the cable network for the automatic search feature.

2.6 exp l anat i o n of the term "symb ol rat e"

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 user bits to the complete transmitted bits. The output symbol rate is calculated as follows:
256-QAM: SR (A) = FEC x 1/4 x SR (E) 128-QAM: SR (A) = FEC x 2/7 x SR (E) 64-QAM: SR (A) = FEC x 1/3 x SR (E) 32-QAM: SR (A) = FEC x 2/5 x SR (E)
16-QAM: SR (A) = FEC x 1/2 x SR (E) 4-QAM: SR (A) = FEC x 1/1 x SR (E)
Example:
Output symbol rate SR (A) 64-QAM, Input symbol rate SR (E) = 27,500
kSymb/s
FEC= 3/4,
SR (A)

transponde r with a very l ow symbol rat e (sCpC station)

The extremely low data rate means that the output symbol rate is very low. If

de fined s ymbo l rat es

Some cable operators specify a fixed symbol rate (e.g. 6,900 kSymb/s).
= 3/4 x 1/3 x 27,500

"FEC = 3/4".
there are reception problems with different digital receivers, set output symbol rate to a higher value.

6,875 kSymb/s

3 installation

– 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 module, switch off the head-end station or
unplug the power cable from the mains power socket.
– Take measures to protect against ESD!
• Open the housing of the head-end station in accordance with the assembly instructions for the CSE 2800.

3.1 retr o f itting a Ca module

The cassette is equipped with two common interfaces. This allows you to con-
nect two CA modules 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.
– Check with the distributor or manufacturer of the CA modules to be used
to ensure that they are suitable for descrambling 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 modules, please read the corresponding oper-
ating manuals from the respective providers.
• Insert the smart card
1 into the CA module 2 so that the chip 3
on the
smart card faces the thicker side (top) of the CA module (fig. 1).
• Push the CA module 2 without canting into the guide rails 4 of the com­mon interface 5 according to the following picture and contact it to the common interface.

3.2 ins tal ling th e Qam module

–
Check that the plug contacts of the CA module are tightly seated in the terminal strips on the
common
interface of the
QAM
module and make
sure there is reliable contact.
– When installing a module, make sure that it is inserted in one of the long,
numbered grooves in front of the contact strip on the board at the rear wall of the housing.
– The shorter, non-numbered grooves without a contact strip on the board at
the rear wall of the housing are for add-on modules only.
• Open the housing of the head-end station in accordance with the assembly instructions for the CSE 2800.
• Open the locking device 1 in the direction of the arrow (fig. 2).

—> The QAM signal is normally transmitted with a bandwidth of 8 MHz.
This means that you can only use the existing channel grid in the range of channels C21…C69 (frequency grid 8 MHz).
The CCIR channel grid is 7 MHz in the range of the lower frequency
bands (channels C5 … C12, S2…S20). If 8 MHz QAM signal packages are transmitted in these channel ranges, this will result in interference (overlapping) and transmission problems.
For programming in these channel ranges and in the frequency rang-
es below them, we recommend starting with frequency 306 MHz going back in steps of 8 MHz (see frequency table on page 37). Please note thereby that many receivers cannot receive the channel ranges S21…S41 (306 … 466 MHz).
