AGILITY AND ADJACENT CHANNELSClassA modules feature frequency agility handled by a high-performance PLL heterodyne double conversion. The broadband noise floor generated isexceptionally low, so multiple modules can be installed in the headend with very little deterioration of the CNR. The use of SAW filters provides, on theother hand, a true vestigial sideband response that enables frequency planning using adjacent channels.These characteristics mean the installations are highly flexible and the maintenance problems are simplified.

VIDEO/AUDIO LOOP AND BISS OPERATIONClassA receivers have an external video/audio loop that is switchable under control software. So, these receivers can be used in scrambling systems(vHOTEL from IKUSI, for example).The receivers can also operate in BISS systems (Basic Interoperable Scrambling Systems).

FUNCTIONAL DESCRIPTION OF THE TPC PROCESSORSIn a TPC module can be distinguished three main sections:

a) "Input Channel →→→→→ IF" conversion. Includes a delayed AGC circuitry that operates in the 50-90 dBμV (analog) or40-80 dBμV (digital) input level ranges.

b) IF filtering. A double SAW filter is used, what provides very high selectivity (>70 dB at ±5.25 MHz from the centre for8MHz-wide channels).

c) "IF →→→→→ Output Channel" conversion. The output level can be adjusted between 65 and 80 dBμV.Range includes two models: the TPC-110, which can be programmed remotely if an HMS control unit is installed in theheadend, and the economical TPC-010 model, which can be programmed only locally with the SPI-300 programming unit.

Programming of a TPC processor involves the following selections and settings:- Input Frequency. Is the picture carrier for analog channel and the central frequency for digital channel.- Tuning Offset. Applicable when a strong adjacent channel interferes with the channel being processed.- AGC on/off. The automatic gain control must be switched off for system L channels.- Manual Gain Control, only if the AGC function has been disabled.- IF Bandwidth. Two options: 7 or 8 MHz.- Output Frequency. Same indications stated above for input frequency.- RF output level. 15 dB adjustable.

The output signal has very low phase noise and very clean wideband spectrum. On the other hand, a vey low broadbandnoise floor (< -75 dBc) permits using multiple processors in a headend with very little deterioration of the CNR.

Simple cabling of TPC headendsThe TPC modules feature two directionally coupled input and output ports. Antenna or cable network signal can therefore be directly fed into the inputport of the first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated whichforms the channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier —the HPA module or an ex-ternal wideband amplifier— which then feeds the distribution network. For power connection, each module has two DC banana sockets that allow tobuild a +12 VDC cascade. A third banana socket is available to connect the power for an optional mast-head preamplifier.

ClassA HEADENDS«TDI» — COFDM-QAM Transmodulation Equipment CE

TDI HEADENDS● Digital Transmodulation (COFDM→QAM) with Transport Stream Processing. The COFDM channels located in the 174-230 MHz or 470-862 MHz bands

are transformed to QAM channels (16 to 256 symbols) located in the 47-862 MHz band.● A TDI headend includes:

- As many TDI Transmodulators as QAM channels to be distributed.- One HPA Amplifier that amplifies the sum of the combined output QAM channels from the transmodulators.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The TDI headends provide a QAM multichannel signal whose level is appropriate to feed the distribution network. An extension input at the HPA amplifierallows easy coupling of the wideband 47-862 MHz signal provided by another existing headend. The user requires a DVB-C Receiver to convert the QAMsignals into the appropriate signals that can be accepted by a conventional TV set, and to control access to encrypted TV programmes.

FUNCTIONAL DESCRIPTION OF THE TDI TRANSMODULATORSA TDI transmodulator carries out the complete channel processing from the input to the output:

- tunes a COFDM digital channel of the 174-230 MHz or 470-862 MHz bands,- demodulates the signal being received,- processes the transport stream, and- re-modulates it in QAM format (16, 32, 64, 128 or 256 symbols) on an RF channel that is selectable

within the 47-862 MHz frequency range.

Programming of the module involves the following selections and settings:- Central Input Frequency (125 kHz steps)- Bandwidth (7 or 8 MHz)- Hierarchy Level (high or low priority)- Central Output Frequency (250 kHz steps)- Output Modulation Scheme (16, 32, 64, 128 or 256QAM)- Roll-Off factor ("half Nyquist filter")- RF Output Level- Output Symbol Rate- Optional Blockade of Services, PIDs and Conditionnal Accesses, with Regeneration of Tables- NIT Adaptation

Simple cabling of TDI headendsThe TDI transmodulators feature two directionally coupled input and output ports. Antenna signal can therefore be directly fed into the input port ofthe first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated which formsthe channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier —the HPA module or an externalwideband amplifier— which then feeds the distribution network. For power connection, each module has two DC banana sockets that allow to build a+12 VDC cascade. A third banana socket is available to connect the power for an optional mast-head preamplifier.

Local programming is carried out with the SPI-300 unit, which is connected individually to each transmodulator. In order to perform NIT adaptation, theIKUSUP bus must be installed; the last module at the right end of the IKUSUP cascade carries out this adaptation. Programming and control can be per-formed remotely if an HMS unit has been installed in the headend.

— Example of «TDI» headend for eight digital terrestrial channels. Contains 8 Transmodulators,1 Amplifier and 2 Power Supplies, all fixed on 2 horizontally joined baseplates.

ClassA HEADENDS«TDC» — Digital Terrestrial TV Reception Equipment with Embedded CA CE

TDC HEADENDS● Terrestrial TV reception, standard DVB-T / MPEG-2 (EN 300 744).● De-encryption and Digital-to-Analogue Transmodulation Process (Encrypted COFDM → Clear AM). The encrypted TV programmes transmitted in COFDM

Terrestrial-TV channels are de-encrypted and presented on conventional vestigial side band VHF/UHF channels (any TV system and Colour system).● A TDC headend includes:

- As many appropriate Embedded CA (Conditional Access) Receiving Modules as de-encrypted TV programmes to be distributed.- One HPA Amplifier that amplifies the sum of the combined output TV channels from the receivers.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The TDC headends provide a TV multichannel signal whose level is appropriate to feed the distribution network. With a TDC installed in the headend, the enduser does not require a Set Top Box or any additional devices to view the de-encrypted digital TV programs being distributed. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

FUNCTIONAL DESCRIPTION OF THE TDC RECEIVERSA TDC embedded CA receiving module carries out a complete channel processing from the input to the output:

- tunes a COFDM digital channel within the BIII or UHF bands,- selects an encrypted TV programme from the multiplex being received, and- de-encryptes and presents it on a conventional TV channel which is selectable throughout the 45-862 MHz band.

Range includes different models in terms of the embedded conditional access, as well as the TV System and theAudio System for the single-channel output signal. A front slot allows to insert the operator's smart card.

Programming of each module involves the following selections and settings:- Central Input Frequency (125 kHz steps).- Bandwidth (7 or 8 MHz).- Hierarchy Level (high or low priority).- TV Programme and Audio Service.- Parameters of the output TV channel (video carrier frequency, TV system, colour system,

video modulation depth, audio modulation index, carrier level ratio, output level).- Image Format. Possible conversions are 16:9 to 4:3 Pan&Scan and 16:9 to 4:3 Letter-Box.

Simple cabling of TDC headendsThe TDC receiving modules feature two directionally coupled input and output ports. Antenna signal can therefore be directly fed into the input port ofthe first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated which formsthe channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier —the HPA module or an externalwideband amplifier— which then feeds the distribution network. For power connection, each module has two DC banana sockets that allow to build a+12 VDC cascade. A third banana socket is available to connect the power for an optional mast-head preamplifier.

The TDC receivers have video/audio loop-through capacity. The external loop is switched under control software.

Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming is possible only if an HMScontrol unit is installed in the headend.

— Example of «TDC» headend for eight encrypted digital TV programmes. Contains 8 Receivers,1 Amplifier and 2 Power Supplies, all fixed on 2 horizontally joined Base-plates.

ClassA HEADENDS«SRF» — Free-To-Air Digital Satellite TV Reception Equipment CE

SRF HEADENDS● Satellite TV reception, standard DVB-S / MPEG-2 (EN 300 421).● Digital-to-Analogue Transmodulation Process (QPSK → AM) that presents the clear TV programmes transmitted in QPSK Sat-TV channels on

conventional VHF/UHF channels (VSB vestigial side band or DSB double side band; any TV system and Colour system).● An SRF headend includes:

- As many SRF Receiving Modules as free-to-air TV programmes to be distributed.- One HPA Amplifier that amplifies the sum of the combined output TV channels from the receivers.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The SRF headends provide a TV multichannel signal whose level is appropriate to feed the distribution network. With a SRF installed in the headend, theend user does not require a Set Top Box or any additional devices to view the clear digital TV programs being distributed. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

FUNCTIONAL DESCRIPTION OF THE SRF RECEIVERSAn SRF receiving module carries out the complete channel processing from the input to the output:

- tunes a QPSK Sat-IF digital channel in the 950-2150 MHz band,- selects a TV programme from the multiplex received, and- directs it to a conventional TV channel which is selectable throughout the 45-862 MHz band.

Range includes different models for VSB or DSB output channel spectrums; for B/G, D/K, I, L or M/N TV systems; and formono or A2 stereo/dual sounds.

Programming of each module involves the following selections and settings:- Central Input Frequency (1 MHz steps).- Input Symbol Rate (0.001 MS/s steps).- TV Programme and Audio Service. (Or a Radio Programme. Image will be black).- Parameters of the output TV channel (video carrier frequency, TV system, colour system,


Models featuring VSB output are utilizable for adjacent channel operation. If this operation is not required, existing model featuring DSB output may beused without problems. The first ones present, on the other hand, a very low broadband noise floor (< -75 dBc) that permit to use multiple modules in theheadend with very little deterioration of the CNR.

Simple cabling of SRF headendsThe SRF receiving modules feature two directionally coupled input and output ports. Sat-IF signal can therefore be directlyfed into the input port of the first module, which in turn passes it through the coupler to the next and so forth. On the outputside, the same procedure is repeated which forms the channel coupling. The sum of the combined channels is turn con-nected in the same way to the drive amplifier —the HPA module or an external wideband amplifier— which then feeds thedistribution network. For power connection, each module has two DC banana sockets that allow to build a +12 VDC casca-de. A third banana socket is available to connect the power for the attached LNB.

An external video/audio loop, which is switched under control software, is available on models SRF-1xx. The loop is not avai-lable in the so called economical models (SRF-0xx).

Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming ispossible only if an HMS control unit is installed in the headend. The SRF-0xx economical models do not have IKUSUP sockets and cannot therefore beprogrammed remotely.

FUNCTIONAL DESCRIPTION OF SRC RECEIVERSAn SRC receiving module with CAM + Operator's Smart Card inserted, carries out a complete channelprocessing from the input to the output:

- tunes a QPSK Sat-IF digital channel in the 950-2150 MHz band,- selects an encrypted TV programme from the multiplex being received, and- de-encryptes and presents it on a conventional TV channel that is selectable

throughout the 45-862 MHz band.Range includes different mono sound models for VSB or DSB output channel spectrumsand for available or non-available remote programming function.Programming of each module involves the following selections and settings:

- Central Input Frequency (1 MHz steps).- Input Symbol Rate (0.001 MS/s steps).- TV Programme and Audio Service. (Or a Radio Programme. Image will be black).- Parameters of the output TV channel (video carrier frequency, TV system, colour system,


Models featuring VSB output are utilizable for adjacent channel operation. If this operation is not required, existing model featuring DSB output may be usedwithout problems. The first ones present, on the other hand, a very low broadband noise floor (< -75 dBc) that permits the use of multiple modules in a hea-dend with very little deterioration of the CNR.

Simple cabling of SRC headendsThe SRC receiving modules feature two directionally coupled input and output ports. Sat-IF signal can therefore be directlyfed into the input port of the first module, which in turn passes it through the coupler to the next and so forth. On the outputside, the same procedure is repeated which forms the channel coupling. The sum of the combined channels is turn connec-ted in the same way to the drive amplifier —the HPA module or an external wideband amplifier— which then feeds the distri-bution network. For power connection, each module has two DC banana sockets that allow to build a +12 VDC cascade. Athird banana socket is available to connect the power for the attached LNB.An external video/audio loop, which is switched under control software, is available on model SRC-111. The loop is not availablein the so called economical models (SRC-011 and SRC-051).Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming ispossible only if an HMS control unit is installed in the headend. The SRC-0xx economical models do not have IKUSUP sockets and cannot therefore be pro-grammed remotely.

ClassA HEADENDS

MTI HEADENDS● Digital transmodulation (QPSK→COFDM) with Common Interface and Transport Stream Processing. The QPSK channels located in the Sat-IF frequency

band (950-2150 MHz) are transformed to COFDM channels located in the 45-682 MHz band. Discretionary programme de-encrypting, according to theinserted CAM module.

● An MTI headend includes:- As many MTI Transmodulators as COFDM channels to be distributed. A front slot on each transmodulator allows to insert

a Conditional Acces Module (CAM) for de-encrypting the encrypted programmes.- One HPA Amplifier that amplifies the sum of the combined output COFDM channels from the transmodulators.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, one Housing unit.- If the headend is large, one or more AMX-400 combiners.

The MTI headends provide a COFDM multichannel signal whose level is appropriate to feed the distribution network. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend. The user will be able to use his DTT (digitalterrestrial television) TV set to view the programmes of the satellite channels processed by the MTI headend.

FUNCTIONAL DESCRIPTION OF THE MTI TRANSMODULATORSAn MTI transmodulator carries out the complete channel processing from the input to the output:

- tunes a QPSK digital channel of the 950-2150 MHz band,- demodulates the signal being received,- processes the transport stream (with programme de-encrypting if a "CAM + Operator Card" couple is installed), and- re-modulates it in COFDM format on an RF channel that is selectable within the 47-862 MHz frequency range.

Module programming involves the following selections and settings:- Central QPSK Input Frequency (1 MHz steps)- Input Symbol Rate (0.001 MS/s steps)- Central COFDM Output Frequency (1 kHz steps)- Output Channel Bandwidth (6, 7 or 8 MHz; also 5 MHz on DVB-H)- Output Operation Mode (2K or 8K; also 4K on DVB-H)- Output Constellation (QPSK, 16QAM or 64QAM)- Output Code Rate (1/2, 2/3, 3/4, 5/6 or 7/8)- Output Guard Interval (1/4, 1/8, 1/16 or 1/32)- RF Output Level- FFT Window (Fast Fourier Transform), to reduce interference on adjacent channel- In-depth interleaving (only on DVB-H; with 2K and 4K modes)- Discretionary de-encrypting of one or more Services (programmes)- Optional Blockade of Services, PIDs and Conditional Accesses, with Regeneration of Tables- NIT Adaptation

Simple cabling of MTI headendsThe MTI transmodulators feature two directionally coupled input and output ports. Sat-IF signal can therefore be directly fed into the input port of thefirst module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated which forms thechannel coupling.

For power connection, each module has two DC banana sockets that allow to build a+12 VDC cascade. A third banana socket is available to connect the power for the attached LNB.

Local programming is carried out with the SPI-300 unit, which is connected individually to each transmodulator. In order to perform NIT adaptation, theIKUSUP bus must be installed; the last module at the right end of the IKUSUP cascade carries out this adaptation. Programming and control can be per-formed remotely if an HMS unit has been installed in the headend.

MDI HEADENDS● Digital Transmodulation (xPSK→QAM). The QPSK or 8PSK channels located in the Sat-IF frequency band (950-2150 MHz) are transformed to QAM

channels (16 to 256 symbols) located in the 45-862 MHz band. The equipment includes two transmodulator models: MDI-900 for DVB-S, and MDI-910for DVB-S and DVB-S2. Both models perform transport stream processing, and the MDI-910 features moreover common interface.

● An MDI headend includes:- As many MDI Transmodulators as QAM channels to be distributed. A front slot on the MDI-910 allows to insert a

Simple cabling of MCP headendsVideo and audio input ports of the modulators are disposed at the top of the front panels. The RF output of each module is presented at the bottom on twodirectionally coupled F ports, so a channel coupling line may be formed along the MCP assembly by using the supplied plug bridges. The sum of thecombined channels is connected to the drive amplifier —the HPA module or an external wideband amplifier—. For power connection, each module has twoDC banana sockets to perform a +12 VDC cascade.Programming is carried out with the SPI-300 unit, which is connected to each module individually. The process involves the following selections and settings:

— Example of «MCP» headend with 7 Modulators, 1 Amplifier and 1 Power Supply, all fixed on 1 baseplate.

Audio functionalityThe MCP modulators family includes different models for mono and stereo/dual operation. Audio connection functionality on each model is not limited tothe basic one —use of 1 signal source for mono models and 2 signal sources for stereo/dual models —, but it allows the reciprocal one, that is to say,use of 2 sources, L and R, for mono models and 1 source for stereo/dual models. Therefore, it is possible to use a mono model with a stereo/dual source(L and R signals are sumed by the modulator itself) and a stereo/dual model with a mono source —the output TV channel will be, obviously, a monosound channel. The following diagrams show the mentioned possibilities of use :

APPLICATIONThe HMS-120 and HMS-130 units provide advanced remote control features for ClassA headends. These features include sendingalarms via SMS, detecting RF levels of the headend multichannel output signal, automatically equalising these levels and thepossibility of scheduling parameter settings, generating OSD messages and updating firmwares. The HMS-130, besides this,generates an INFO Channel that displays images and sounds previously entered as JPEG and MP3 files. The HMS units include aweb server which allows the control operation to be performed from any local or remote PC using a standard browser.The control unit is positioned in the ClassA headend as the last module on the right of the cascade of signal modules (processors,receivers, transmodulators, regenerators). The installation of the communication local bus (IKUSUP) along the modules is required,as well as the connection of a tapped signal from the HPA amplifier to the HMS control unit.

Access interfacesThe HMS control units have two interfaces for remote communication:

● A GSM/GPRS interface which uses an internal modem to perform control operations from any remote PC connected to themodem telephone number. A slot on the front panel allows to insert the SIM card.

● An Ethernet interface which, via an external modem/router, allows monitoring from any remote PC connected to Internet. If the headend is installed ina LAN environment, the control operations can be performed from any PC integrated therein. The interface also allows local use of a PC connecteddirectly connected to the HMS module.

ClassA HEADENDS«CRF» — Free-To-Air Digital Cable TV Reception Equipment CE

CRF HEADENDS● Cable TV reception, standard DVB-C / MPEG-2 (EN 300 429).● Digital-to-Analogue Transmodulation Process (QAM → AM) that presents the clear TV programmes transmitted in QAM Cable-TV channels on

conventional vestigial side band VHF/UHF channels (any TV system and Colour system).● A CRF headend includes:

- As many CRF Receiving Modules as free-to-air TV programmes to be distributed.- One HPA Amplifier that amplifies the sum of the combined output TV channels from the receivers.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The CRF headends provide a TV multichannel signal whose level is appropriate to feed the distribution network. With a CRF installed in the headend, theend user does not require a Set Top Box or any additional devices to view the clear digital TV programs being distributed. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

FUNCTIONAL DESCRIPTION OF THE CRF RECEIVERSA CRF receiving module carries out the complete channel processing from the input to the output:

- tunes a QAM modulated RF carrier in the 51-858 MHz band,- selects a TV programme from the multiplex being received, and- directs it on a conventional TV channel which is selectable throughout the 45-862 MHz band.

Range includes two mono sound models for B/G and D/K/I/L systems.

Programming of each module involves the following selections and settings:- Central Input Frequency (250 kHz steps).- Input Symbol Rate (0.001 MS/s steps).- Input Modulation Scheme (16, 32, 64, 128 or 256QAM)- TV Programme and Audio Service.- Parameters of the output TV channel (video carrier frequency, TV system, colour system,


Simple cabling of CRF headendsThe CRF receiving modules feature two directionally coupled input and output ports. Incoming QAM signal can therefore be directly fed into the inputport of the first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated whichforms the channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier —the HPA module or an ex-ternal wideband amplifier— which then feeds the distribution network. For power connection, each module has two DC banana sockets that allow tobuild a +12 VDC cascade.

The CRF receivers have video loop-through capacity. The external loop is switched under control software.

Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming is possible only if an HMScontrol unit is installed in the headend.

— Example of «CRF» headend for eight clear digital cable TV programmes. Contains 8 Receivers,1 Amplifier and 2 Power Supplies, all fixed on 2 horizontally joined baseplates.

ClassA HEADENDS«CRC» — Digital Cable-TV MultiCrypt Reception Equipment CE

CRC HEADENDS● Reception of encrypted Cable TV programs. Standard DVB-C / MPEG-2 (EN 300 429).● Receiving Modules with Common Interface (EN 50221). The encrypted TV programmes transmitted on QAM Cable-TV channels are de-encrypted and

presented on conventional VHF/UHF channels (VSB vestigial side band; any TV system or Colour system).● A CRC headend includes:

- As many CRC Receiving Modules as de-encrypted TV programmes to be distributed. At each module,one CAM (Conditional Access Module) containing the Operator's Smart Card must fit the front panel slot.

- One HPA Amplifier that amplifies the sum of the receivers' output TV channels.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The CRC headends provide a TV multichannel signal whose level is appropriate to feed the distribution network. With an CRC installed in the headend,the end user does not require a Set Top Box or any additional devices to view the de-encrypted digital TV programs being distributed. An extension inputat the HPA amplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

— Example of «CRC» headend for eight encrypted digital cable TV programmes. Contains 8 CRC-011Receivers, 1 Amplifier and 2 Power Supplies, all fixed on 2 horizontally joined Base-plates.

● CAM modules are not supplied by IKUSI

FUNCTIONAL DESCRIPTION OF THE CRC RECEIVERSA CRC receiving module with CAM + Operator's Smart Card inserted, carries out a complete channelprocessing from the input to the output:

- tunes a QAM-modulated RF carrier in the 51-858 MHz band,- selects an encrypted TV programme from the multiplex being received, and- de-encryptes and presents it on a conventional TV channel that is selectable

throughout the 45-862 MHz band.Range includes two mono-sound models, both featuring VSB output spectrum.Programming of the module involves the following selections and settings:

- Central Input Frequency (250 kHz steps).- Input Symbol Rate (0.001 MS/s steps).- Input Modulation Scheme (16, 32, 64, 128 or 256QAM).- TV Programme and Audio Service.- Parameters of the output TV channel (video carrier frequency, TV system, colour system,


The two available CRC receivers are utilizable for adjacent channel operation. Both present, on the other hand, a very low broadband noise floor (< -75 dBc)that permits the use of multiple modules in a headend with very little deterioration of the CNR.

Simple cabling of CRC headendsThe CRC receiving modules feature two directionally coupled input and output ports. Incoming QAM signal can therefo-re be directly fed into the input port of the first module, which in turn passes it through the coupler to the next and soforth. On the output side, the same procedure is repeated which forms the channel coupling. The sum of the combinedchannels is turn connected in the same way to the drive amplifier —the HPA module or an external wideband ampli-fier— which then feeds the distribution network. For power connection, each module has two DC banana sockets thatallow to build a +12 VDC cascade.An external video/audio loop, which is switched under control software, is available on model CRC-121. The loop is notavailable in the so called economical model (CRC-011).Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming ispossible only if an HMS control unit is installed in the headend. The CRC-011 economical model does not have IKUSUP socketsand cannot therefore be programmed remotely.

ClassA HEADENDS«CGT» — Cable TV QAM-QAM Regeneration Equipment CE

CGT HEADENDS● Digital Transmodulation (QAM → QAM) with Transport Stream Processing. Regenerates the QAM modulated carriers by correcting the errors arisen

in the data stream along the cable network. Carrier frequencies (from 47 to 862 MHz) and modulation scheme (16 to 256QAM) of the errorlessregenerated QAM signals can be set equal or different to those of the QAM incoming signals.

● A CGT headend includes:- As many CGT Regenerators as QAM channels to be regenerated.- One HPA Amplifier that amplifies the sum of the combined output QAM channels from the regenerators.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The CGT headends provide a QAM multichannel signal whose level is appropriate to feed the distribution network. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

FUNCTIONAL DESCRIPTION OF THE CGT REGENERATORSA CGT regenerator carries out the complete channel processing from the input to the output:

- tunes a QAM modulated RF carrier in the 47-862 MHz band,- demodulates this carrier,- corrects errors of data stream,- processes the transport stream, and- re-modulates the errorless data signal on a QAM channel that is selectable within the 47-862 MHz frequency

range.

Programming of the module involves the following selections and settings:- Central Input Frequency (250 kHz steps)- Input Symbol Rate (0.001 MS/s steps)- Input Modulation Scheme (16, 32, 64, 128 or 256QAM)- Central Output Frequency (250 kHz steps)- Output Modulation Scheme (16, 32, 64, 128 or 256QAM)- Roll-Off factor ("half Nyquist filter")- RF output level- Output Symbol Rate- Optional Blockade of Services, PIDs and Conditionnal Accesses, with Regeneration of Tables- NIT Adaptation

Simple cabling of CGT headendsThe CGT regenerators feature two directionally coupled input and output ports. Incoming QAM signal can therefore be directly fed into the input portof the first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated which for-ms the channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier —the HPA module or an exter-nal wideband amplifier— which then feeds the distribution network. For power connection, each module has two DC banana sockets that allow tobuild a +12 VDC cascade.

Local programming is carried out with the SPI-300 unit, which is connected to each module individually. In order to perform NIT adaptation, theIKUSUP bus must be installed; the last module at the right end of the IKUSUP cascade carries out this adaptation. Programming and control can be per-formed remotely if an HMS unit has been installed in the headend.

— Example of «CGT» headend for eight QAM modulated channels. Contains 8 Regenerators,1 Amplifier and 2 Power Supplies, all fixed on 2 horizontally joined baseplates.

ClassA HEADENDS«TRF» — Free-To-Air Digital Terrestrial TV Reception Equipment CE

TRF HEADENDS● Terrestrial TV reception, standard DVB-T / MPEG-2 (EN 300 744).● Digital-to-Analogue Transmodulation Process (COFDM → AM) that presents the clear TV programmes transmitted in COFDM Terrestrial-TV channels

on conventional VHF/UHF channels (VSB vestigial side band or DSB double side band; any TV system and Colour system).● A TRF headend includes:

- As many TRF Receiving Modules as free-to-air TV programmes to be distributed.- One HPA Amplifier that amplifies the sum of the combined output TV channels from the receivers.- One or more CFP Power Supplies.- One or more Rack-Frames or wall-fixing Base-Plates. The base-plates can be joined horizontally.- Usually, housing units for the base-plates.- If the headend is large, one or more AMX-400 combiners.

The TRF headends provide a TV multichannel signal whose level is appropriate to feed the distribution network. With a TRF installed in the headend, theend user does not require a Set Top Box or any additional devices to view the clear digital TV programs being distributed. An extension input at the HPAamplifier allows easy coupling of the wideband 47-862 MHz signal provided by another existing headend.

FUNCTIONAL DESCRIPTION OF THE TRF RECEIVERSA TRF receiving module carries out the complete channel processing from the input to the output:

- tunes a COFDM digital channel within the BIII or UHF bands,- selects a TV programme from the multiplex being received, and- directs it to a conventional TV channel which is selectable throughout the 45-862 MHz band.

Range includes different models for VSB or DSB output channel spectrums; for B/G, D/K, I, or L TV systems; and formono sound, or A2 or Nicam stereo/dual sounds.

Programming of each module involves the following selections and settings:- Central Input Frequency (125 kHz steps).- Bandwidth (7 or 8 MHz).- Hierarchy Level (high or low priority).- TV Programme and Audio Service.- Parameters of the output TV channel (video carrier frequency, TV system, colour system,


Models featuring VSB output are utilizable for adjacent channel operation. If this operation is not required, existing models featuring DSB output may beused without problems. The first ones present, on the other hand, a very low broadband noise floor (< -75 dBc) that permit to use multiple modules in theheadend with very little deterioration of the CNR.

Simple cabling of TRF headendsThe TRF receiving modules feature two directionally coupled input and output ports. Antenna signal can therefore be directlyfed into the input port of the first module, which in turn passes it through the coupler to the next and so forth. On the outputside, the same procedure is repeated which forms the channel coupling. The sum of the combined channels is turn connectedin the same way to the drive amplifier —the HPA module or an external wideband amplifier— which then feeds the distributionnetwork. For power connection, each module has two DC banana sockets that allow to build a +12 VDC cascade. A third bana-na socket is available to connect the power for an optional mast-head preamplifier.

An external video/audio loop, which is switched under control software, is available on models TRF-1xx. The loop is not availablein the so called economical models (TRF-0xx).

Local programming is carried out with the SPI-300 unit, which is connected to each module individually. Remote programming ispossible only if an HMS control unit is installed in the headend. The TRF-0xx economical models do not have IKUSUP sockets and cannot therefore beprogrammed remotely.
