1.4 Summary of Features

1.4.1 MPEG-2 and DVB Compliance

The Modulator normally accepts an MPEG-2 transport stream in either 188-byte or
204-byte packet format when operating in DVB-S/DSNG or DVB-S2 CCM modes.
Alternatively, an internally generated Pseudo Random Binary Sequence (PRBS) or
Null Packets source may be selected for test purposes. This does not require the
presence of a transport stream input.

1.4.2 Data Inputs

The Modulator base unit has two DVB ASI electrical inputs. When operating in
DVB-S/DSNG or DVB-S2 CCM modes, the incoming data may be in any of the
following four formats:

!"188-byte packets (188 data bytes, contiguous packets)
!"204-byte packets (188 data bytes and 16 RS coding bytes; the coding bytes

are ignored)

!"204-byte packets (188 data bytes and 16 dummy bytes)
!"Unframed data, i.e. without MPEG-2 sync bytes

When operating in DVB-S2 ACM mode, the incoming data may only be in
BBFRAME format.

1.4.3 Transport Stream Rate Adaptation

The modulator is capable of performing transport stream rate adaptation with PCR
correction, allowing it to be used at a fixed symbol rate irrespective of the transport
stream input data rate.

1.4.4 IF Output Model

Modulator model SM6630 has a tuneable 50-180 MHz IF output. Both main and
monitor outputs are provided on this model.

1.4.5 L-Band Output Model

Modulator model SM6635 has a tuneable 950-1750 MHz L-band output. Both main
and monitor outputs, and an L-band carrier combining input are provided on this
model. 24 Vdc power and a 10 MHz reference frequency output, both switchable,
are provided via the main L-band output connector for use by an external
frequency up-converter.

SM6630 and SM6635 Satellite Modulators

1.4.6 DVB-S2 and PREKOR Capability1

Modulator models SM6630 and SM6635 are both DVB-S2 capable and incorporate
TANDBERG Television’s proprietary PREKOR Dynamic Pre-correction system.
The PREKOR system corrects non-linear magnitude and phase distortions, and
group delay distortion introduced by the uplink HPA and satellite transponder. It is
of particular benefit when using higher order modulations such as 16QAM,
16APSK or 32APSK.

1.4.7 Forward Error Correction Coding

Noise and interference can cause some bits to be received in error. Therefore,
Forward Error Correction (FEC) is used to add redundancy, i.e. extra bits, to the
transmitted signal. This allows a large number of errors at the receiver to be
corrected by the FEC decoder. The FEC coding scheme used depends on the
modulation standard selected. The DVB-S and DVB-DSNG standards employ a
concatenated coding scheme consisting of an outer Reed-Solomon (RS) code, bit
interleaving and an inner convolutional code. The DVB-S2 standard employs a
concatenated coding scheme consisting of an outer Bose-Chaudhuri­Hocquenghem (BCH) code and an inner Low Density Parity Check (LDPC) code.

Each FEC coding scheme provides for a number of different code rates, permitting
a trade-off between bit-rate and ruggedness.

1.4.8 Modulation Schemes

DVB-S BPSK and QPSK modulations are available as standard on each base unit
model. Additionally, DVB-DSNG 8PSK and 16QAM modulations are available with
the SM66XX/SWO/HOM option. DVB-S2 QPSK, 8PSK, 16APSK and 32APSK
modulations are available as options.

1.4.9 Symbol Rate Range

Each base unit model has a symbol rate range of 0.1 to 5 Msymbol/s as standard.
Extended symbol rate ranges of 0.1 to 48 Msymbol/s and 0.1 to 66 Msymbol/s are
available with the SM66XX/SWO/48MSYM and SM66XX/SWO/66MSYM options,
respectively.

1.4.10 IF Tilt Correction

Both base unit models incorporate a digital IF tilt corrector having a linear
amplitude versus frequency response with user-controllable slope. This facility is
intended for correcting the frequency dependent attenuation that may be
introduced by long IF output cables.

The appropriate software options are required to enable the DVB-S2 and PREKOR functionality.

See Table 1.2: Software Options.

4.4 Maintenance Philosophy

4.4.1 Operator Level Information

This section provides sufficient information to enable the rectification of apparent
faults by operator action, or else to identify the suspect module, where possible. In
the event that the recommended action fails to clear the abnormal condition, call a
Service Engineer or contact TANDBERG Television Customer Services (see
Preliminary Pages).

WARNING

Hazardous voltages are present within this equipment and may be
exposed if the covers are removed. Only trained AND APPROVED
SERVICE Engineers are permitted to service this equipment.

NOTE

Unauthorised maintenance or the use of non-approved replacements
may invalidate any warranties and/or affect the equipment
specification.

4.4.2 Fault Diagnosis for an Operator

Always investigate the failure symptoms fully, prior to taking remedial action. Fault
diagnosis for the equipment operator is limited to the following tasks, since the
operator should NOT remove the covers of the equipment:

!"Check the front panel Power LED. If this is not lit:

$"Replace external equipment, power source and cables by substitution to

check their performance.

$"Replace the fuse in the power connector at the rear panel.

!"Confirm that the equipment hardware configuration is suitable for the purpose

and has been correctly installed and connected up. Reconfigure/reconnect as
necessary.

SM6630 and SM6635 Satellite Modulators

28

!"Confirm that inappropriate operator action is not causing the problem, and

that the equipment software set-up, via the local terminal, is capable of
performing the task being asked of it. Change set-up parameters as
necessary.
(Refer to the Reference Guide for details.)

!"Use the test menus and options provided by the local terminal.
!"Switch off the equipment if it becomes unusable, or to protect it from further

damage.

!"Check that the fans are unobstructed and working correctly.
!"Call a trained and approved Service Engineer or contact Customer Services.

NOTE

A Modulator must be connected to an Encoder or Multiplexer (or
otherwise fed with a suitable MPEG-2 transport stream) and
monitoring IRD in order to carry out tests in isolation. This may entail
removing the stand-by Encoder or Multiplexer from service, if one is
available, to enable local diagnostics to be carried out.

4.5 Alarm and Failure Reporting

4.5.1 Introduction

This section describes the alarm and fail conditions which cause the alarm/fail
relays to be actuated and which are recorded in the Alarm log. They are dependent
on the cards fitted and, in some cases, the mode of operation of the Modulator.
The alarms reported are dependent upon the Alarm Mask settings. See the
Reference Guide for further details.

This section defines the alarm-reporting scheme in the SM6600 range of Satellite
Modulators.

4.5.2 Alarm Severity Levels

Each alarm is assigned one of six severity levels. These levels provide an
indication of how it is perceived that the capability of the Modulator has been
affected. Those severity levels which represent service affecting conditions ordered
from most severe to least severe are critical, major, minor and warning. The six
severity levels are defined below.

!"The cleared severity level indicates the clearing of one or more previously

reported alarms. This alarm clears all alarms for the Modulator that have the
same alarm type, probable cause and specific problems (if given).

SM6630 and SM6635 Satellite Modulators

29

!"The indeterminate severity level indicates that the severity level cannot be

determined.

!"The warning severity level indicates the detection of a potential or impending

service affecting fault, before any significant effects have been felt. Action
should be taken to further diagnose (if necessary) and correct the problem in
order to prevent it from becoming a more serious service affecting fault.

!"The minor severity level indicates the existence of a non-service affecting

fault condition and that corrective action should be taken in order to prevent a
more serious (for example, service affecting) fault. Such a severity can be
reported, for example, when the detected alarm condition is not currently
degrading the capacity of the Modulator.

!"The major severity level indicates that a service affecting condition has

developed and an urgent corrective action is required. Such a severity can be
reported, for example, when there is a severe degradation in the capability of
the Modulator and its full capability must be restored.

!"The critical severity level indicates that a service affecting condition has

occurred and an immediate corrective action is required. Such a severity can
be reported, for example, when the Modulator becomes totally out of service
and its capability must be restored.

4.5.3 Alarm Groups

The alarm text and severity levels for all Modulator alarms are defined in this
section.

Alarms are divided into four groups according to their source:

!"Alarms sourced by the Host Controller card (slot number 3)
!"Alarms sourced by the Input card (slot number 4)
!"Alarms sourced by the Baseband card (slot number 2)
!"Alarms sourced by the IF card (slot number 1)

Each alarm is capable of being masked.

See the Reference Guide for further details.

5 File Transfer Protocol (FTP)

5.1 Introduction

The SM663X Satellite Modulators provide a File Transfer Protocol (FTP) interface
which is primarily used for code and firmware updates. It is also used for retrieving
logs and configurations as well as uploading configurations.

Any FTP program may be used to access the Modulator’s FTP server. However, it
should be noted that the Modulator will only allow one logon at a time and many
graphical FTP clients use multiple logons. The FTP client supplied with Microsoft
Windows NT 4.0 is recommended. For full instructions regarding using FTP, refer
to the Reference Guide.

NOTE

The Modulator uses a reduced instruction set of standard FTP
commands.

5.2 Downloading Configurations

It is possible to download configurations to the Modulator using FTP. Any of the
eight stored user configurations config01.cfg to config08.cfg may be changed.
The currently implemented configuration active.cfg and the factory default
configuration config09.cfg may not be changed in this way.

To download a configuration, a configuration file must be prepared in a specific
format for the Modulator to understand. It is recommended that a configuration file
be retrieved from the Modulator as a starting point.

The format is as follows:

parameter name : value

SM6630 and SM6635 Satellite Modulators

31

6 Licence Keys

6.1 About Licence Keys

Certain functionality of the Modulator is dependent upon the specific Modulator
model, the hardware options fitted and the software options installed in it. Software
options are enabled or disabled by means of licence keys installed in the
Modulator. A licence key is a string of numbers which, when downloaded to a
Modulator, will enable a specific feature or set of features.

Licence keys may be installed by the user, allowing field upgrading of Modulators
to be performed simply.

Refer to the Reference Guide for full details.

6.2 Obtaining Licence Keys

Licence keys can be purchased from your local TANDBERG Television sales
representative. To obtain a key or keys, specify the options required plus the serial
numbers of the Modulators. These can be obtained from the Terminal or FTP
interfaces.

A single key can enable more than one feature, but will only work on a single
Modulator. When keys are ordered for several Modulators a number of keys may
be supplied as a single licence key file.

6.3 Entering Multiple Licence Keys

The process of entering several keys is the same as for a single key. Entering keys
intended for several Modulators to a single unit does not cause a problem as keys
intended for other Modulators are ignored.

For example, if a system consists of 10 Modulators and they are all to be upgraded
to include higher order modulation (HOM), a large licence key file will be supplied.
This file can be downloaded to all the Modulators within the system.
