2.4 des CriPtion

The double transmodulator cassette is a QPSK-converter, which converts sta-

tions modulated according to DVB-S /

DVB-S2

standard into two QAM-modu-

lated cable signals.
DiSEqC commands can be output via the SAT inputs.
The

cassette

has two digital SAT IF inputs and one RF output. Additionally it
is equipped with an ASI input and an ASI output (ASI – Asynchronous Serial
Interface acc. DIN EN 50083-9).

The transport stream fed via the ASI socket can be inserted into the transport

streams of the receiving stages via the TPS module. The signal path is set in the
menu items input signal path

"INROUTE" and output signal path "OUTROUTE"

.

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 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. Additionally the quality of the transport stream received is dis­played ("CN…").

The integrated TPS module (Transport Stream Processing) processes the data

from the demodulated transport streams.

The 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

PROFI-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 21).

2.6 how the tPs mod ule wo r ks

After decoding QPSK- or 8PSK-modulated signals, the demodulated data

stream can be accessed via the integrated TPS module. This data stream,
also called transport stream, contains 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 required. 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 symbol 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 box 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 de­mands.

- 10 - PHDQ 1000 ASI D

2.7 exP la nat i o n of t h e term "sym bol r ate"

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 64-QAM,
Input symbol rate SR (E) = 27,500

FEC= 3/4,

kSymb/s

SR (A)

= 3/4 x 1/3 x 27,500

kSymb/s

=

6,875 kSymb/s

—> If no "FEC" is stated in the station lists, it can be assumed to be "FEC

= 3/4".

reCePti on fr om a t r a nsPonde r wit h a v ery l ow s ymbol r ate

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 output symbol
rate to a higher value.

defined s ymbo l rat es

Some cable operators specify a fixed symbol rate (e.g. 6,900 kSymb/s).

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.

• If you need the DiSEqC control the input signal must not be fed via the input
distributor. Insert the cable termi nals together with the contact washers in
corresponding open ings (knock-outs). Therefore observe the EMC regula­tions on page 13.

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.

3.4 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 de

scrambl

ing several channels.

– The hardware and software of this cassette have been thoroughly prepared

and tested.

– Any changes made by programme providers 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.
