7.1 to an Unavailability caused by an act or omission of the Customer or
of the Customer's Associates;
7.2 where the Customer Signals, the Customer Uplink Signals or the
Uplink Facilities do not comply with Schedule II or where the
Customer Signals are not received by the Uplink Facilities or the
Customer Uplink Signals are not received by the Customer's
Transponder dues to no fault of SES or any SES Associate.
8. INTERRUPTION, TESTING AND MONITORING
8.1 SES shall be entitled to interrupt the Service(s) and to require
the Customer to cease transmission of the Customer Uplink Signals
where necessary (i) to provide the use of a Spare TWTA, and (ii) for
operational testing, maintenance, monitoring, preventive or curative
repair or adjustment to be carried out either with respect to the
Satellite as a whole or part thereof, or one or more of its
transponders where necessary, in SES' reasonable opinion, to
preserve the integrity of the Satellite or the overall quality of
the satellite transmissions in the short, medium or long term. SES
shall give the Customer as much notice thereof as is practicable in
the circumstances and shall agree with the Customer upon the date
and time of interruption wherever possible.
8.2 SES shall also be entitled to interrupt the Service(s) or to require
the Customer to cease transmission of the Customer Uplink Signals if
the Customer is in breach of its obligations hereunder ALWAYS
PROVIDED THAT if such breach is due to a technical issue, SES shall
not interrupt the Service(s) without allowing the Customer
reasonable period of time to correct it, unless the technical issue
either (i) is interfering with another customer of SES, (ii) could
cause potentially damage or
8
CONFIDENTIAL
degradation to the Satellite or to its proper functioning or (iii)
could affect the quality of the transmissions provided by the
Satellite. Nothing in this CLAUSE 8.2 shall permit SES to interrupt
the Services in circumstances where there is a bona fide dispute
between the parties as to any fees due to be paid under this
Agreement. Any such dispute, if not resolved by negotiation, shall
be dealt with as provided for in CLAUSE 27.
8.3 SES shall monitor the Customer Uplink Signals and the performance of
the Customer's Transponder in accordance with the provisions of
SCHEDULE IV and supply an analysis of the results when so requested
by the Customer. Such data shall be limited to information which SES
can reasonably be expected to obtain and which it can reveal without
liability or breach of any duty to any third party. Such information
shall be kept confidential.
8.4 The Customer shall procure that the operator of the Uplink
Facilities shall assist SES in making any tests to ensure it at
such Facilities and the Customer Uplink Signals comply with
CLAUSE 10.3.
8.5 All Service(s) using the Customer's Transponder shall be uplinked
from the same uplink antenna.
9. PRE-EMPTION
-- INTENTIONALLY DELETED --
10. USE OF TRANSPONDER AND ENGRYPTION
10.1 The frequencies for the Customer Uplink Signals and the Customer
Downlink Signals initially allocated by SES shall be those stated in
SCHEDULE I-B or notified to the Customer before CSD.
10.2 The Customer shall, on CSD, commence transmitting the Service(s) and
thereafter maintain full transmission of the majority of the
Service(s) as described in SCHEDULE III. For the avoidance of doubt
this CLAUSE 10.2 is not designed to interfere with the Customer's
plans for the roll out of the Service(s) and SES accepts that such
plans do not envisage the transmission of a full complement of
Service(s) for the first year of this Agreement and may also mean
that the Customer does not have any Service(s) ready to commence
transmission on CSD.
10.3 The Customer shall procure that the Customer Signals and Customer
Uplink Signals and Uplink Facilities comply with Schedule II and do
not interfere with or damage the Satellite or any of its
transponders.
10.4 The Customer may, if so provided in SCHEDULE V, encrypt the Customer
Signals provided that the Customer, at its costs, provides SES with
ten operational decoders authorised for reception and any other
equipment needed to receive the Customer Downlink Signals.
10.5 SES shall have the right, at any time, to replace the transponder
carrying the Service(s) on the Satellite by another transponder on
any other ASTRA satellite at the same orbital position provided that
the replacement transponder has the same
9
CONFIDENTIAL
polarization, bandwidth and the same uplink and downlink signal
frequency as the transponder used by the Customer prior to such
replacement and provides Minimum Transponder Performance. Unless SES
uplinks the Service(s), SES will endeavour to provide to the
Customer advance notice of 24 hours to perform the necessary
operations to uplink the Service(s) to the other ASTRA satellite. To
avoid a Service interruption, the Customer shall take all necessary
arrangements with the operator of the Uplink Facilities to
accommodate such a transponder replacement and SES will either (i)
move the Customer's Transponder in tandem with any other customer's
transponder on the Satellite or (ii) relax the technical
requirements of the Access Agreement to require only two (2) uplinks
for the three (3) allocated customer's transponders with frequencies
in the E and F bands.
10.6 The Customer shall not use the Customer's Transponder in any way not
specified in this Agreement.
11. SERVICE INFORMATION
The Customer shall provide to SES the Service(s) information in compliance
with Schedule III.
12. COMPLIANCE WITH LAW
12.1 The Customer shall comply to all material extant with all laws,
regulations or provisions relevant for the performance of this
Agreement, shall, where necessary, at all times have and comply with
a broadcasting license or authorization for the Service(s) and shall
promptly inform SES of any material change thereof. If the
Service(s) is not subject to the laws of a member of the European
Union it shall, nevertheless, comply with the provisions of the
"Television Without Frontiers" directive of 3 October 1989, as may
be amended, as transposed into the laws of Luxembourg being
currently Article 6 and Chapter IV of the Luxembourg Electronic
Media Law of 27 July 1991.
12.2 SES shall not exercise its right to terminate this Agreement under
CLAUSE 15.1 by reason of non-compliance by the Customer pursuant to
CLAUSE 12.1 except where such non-compliance has been determined by
a court or other authority with competent jurisdiction or where
otherwise requested by the Government of the Grand Duchy of
Luxembourg. Moreover if compliance with CLAUSE 12.1 would result in
the contravention of any future law or regulation in the Target
Market, its non-compliance with CLAUSE 12.1 shall constitute an
event of force majeure.
13. SES' AUTHORITY
This Agreement is subject to the continuing right of SES to provide the
Customer's Transponder pursuant to the Concession and the Cahier des
Charges. If this right is withdrawn, then this Agreement shall terminate
automatically unless the Government of Luxembourg wishes to undertake SES'
rights and obligations hereunder. In either case, SES shall be discharged
of all liability and obligation to the Customer subject to CLAUSE 16.
14. ASSIGNMENT
14.1 Subject to the remainder of this CLAUSE 14 the Customer shall not
assign, transfer, sub-let, or otherwise allow any third party to
directly or indirectly exercise its rights, in whole or in part,
under this Agreement. For the purpose hereof, an assignment
10
CONFIDENTIAL
shall also include a change in the control of the Customer or of a
substantial part of its assets or business.
14.2 SES hereby authorises the Customer at any time to assign its rights
under this Agreement to (a) any affiliate or (b) Procable Sp Z O. O.
("Procable") provided that the Customer retains not less than a 33%
shareholding in Procable, and in any such event on condition that
the Customer agrees to continue to be bound by all its obligations
and liabilities hereunder and to hold SES harmless from any breach
of this Agreement by its Assignee. For the purposes of this CLAUSE
14.2, a company will be regarded as an affiliate of the Customer if
the Customer holds not less than a 50% interest in the shares or
equivalent of that company or if the company holds at least 50%
interest in the Customer or a company being under common control
with the Customer.
14.3 Upon SES' and the Luxembourg Government prior written consent, which
shall not be unreasonably withheld or delayed, the Customer may
sub-contract the benefit of this Agreement to any third party
provided that (i) no such sub-contract shall relieve the Customer of
its obligations and liabilities under this Agreement and the
Customer shall be responsible for the acts, default and omissions of
the sub-contractor, its employees and agents as fully as if they
were acts, default, omissions of the Customer itself and (ii) the
Customer will share revenues exceeding the charge payable in the
relevant year with SES on a 50/50 basis.
15. TERMINATION
In addition to the termination rights provided herein including without
limitation the Customer's right to terminate as specified in CLAUSE 6.3, a
party may terminate this Agreement forthwith by written notice if the other
party;
15.1 commits a material breach of its obligations hereunder and fails to
remedy such breach (if capable of remedy) within thirty (30) days of
written notice from the party requiring such breach to be remedied
(for the avoidance of doubt, circumstances giving rise to the right
to terminate under CLAUSE 3.2 or CLAUSE 6.3 do not constitute a
material breach);
15.2 is unable to pay its debts as they mature; becomes insolvent; is
subject to bankruptcy, reorganisation, moratorium, insolvency or
similar proceedings for the relief of financially distressed
debtors; is subject to winding up, dissolution or liquidation
(judicial or non-judicial) proceedings; voluntarily or involuntarily
suspends or discontinues its business; liquidates or sells a
substantial part of its assets; makes an assignment for the benefit
of its creditors; or is subject to the appointment of a receiver,
liquidator or other third party over its assets or business; or
15.3 has been prevented by an event of force majeure from materially
performing its obligations hereunder for sixty (60) days or more.
SES will waive its right to terminate the Agreement if and for such
period of time the Customer continues to pay the charge hereunder.
11
CONFIDENTIAL
16. EFFECT OF TERMINATION
16.1 Where the Agreement is terminated (i) by the Customer, pursuant to
CLAUSES 6.3, 15.1 or 15.2, (ii) by either party, pursuant to CLAUSE
15.3, or (iii) automatically pursuant to CLAUSE 13, then SES shall
refund to the Customer the pro rata temporis portion of the advance
payments made by the Customer pursuant to SCHEDULE VI relating to
the unexpired portion of the Payment Period in progress on the date
of termination. SES may deduct from such amount all payments, taxes
and duties payable to governments or other entities for which the
Customer is liable hereunder and all sums owed to SES at that time.
16.2 Where SES terminates this Agreement pursuant to CLAUSES 15.1 or
15.2, the Customer shall forthwith pay to SES any sum owed by the
Customer to SES at that time and shall continue to be liable for and
to pay the charge provided in SCHEDULE VI (as if the Agreement had
not been terminated) until such time as SES allocates the Customer's
Transponder to another customer. SES shall have no obligation to
market the Customer's Transponder in priority to unused transponder
capacity on SES' satellites and for a price inferior to that
payable by the Customer to SES (unless the Customer makes up for the
difference); however, SES shall use its reasonable efforts to
mitigate its losses. If the Customer's Transponder is allocated to
another customer, SES shall refund to the Customer the pro rata
temporis portion of the advance payments made by the Customer
pursuant to SCHEDULE VI relating to the unexpired portion of the
Payment Period in progress on the date at which the other customer
starts transmitting.
17. FORCE MAJEURE
Neither party shall be considered to be in breach or be liable for any
damage suffered by the other party or its Associates, by reason of any
failure to perform any obligation hereunder if and for so long as such
failure is the result of an event of force majeure. Subject to CLAUSE 15.3,
the respective obligations of both parties shall be suspended for such time
as such an event prevents either party from performing its obligations.
18. LIMITATION OF LIABILITY - EXCLUSIVITY OF REMEDIES
18.1 Without prejudice to CLAUSES 5, 6 AND 16, SES shall not be liable
to the Customer or to the Customer's Associates in any way
whatsoever, except for its gross negligence ("faute lourde") or
wilful misconduct ("dol").
18.2 The remedies expressly provided in this Agreement are the sole
remedies available to the parties and the parties waive any other
rights that they may have.
19. INDEMNITIES
19.1 The Customer shall totally indemnify SES and SES' Associates and
customers against all claims, losses, damages, expenses arising

respect of any claim brought against it for which it may seek an
indemnity under this CLAUSE 19 without the prior written consent of
the indemnifying party and the indemnifying party shall have the
right to control any such proceedings at its own costs and expenses.
20. CONFIDENTIALITY
Each party shall, and shall procure that its Associates shall, both
throughout the Term and thereafter, keep confidential the provisions of

Wroclaw 52.5 52
Betzdorf 51 51
It is understood that SES shall have no obligation to monitor or measure
the Minimum Transponder Performance in any sites listed above save for
Betzdorf.
2. "RECEIVED SIGNAL POWER" is defined as signal power in dBW on the ground in
Luxembourg measured by a measurement test set-up according to standard
engineering practice as described in SCHEDULE I-E. If the measurement is
not performed under clear sky conditions, the measured value shall be
corrected to account for the effect of weather and propagation conditions.
3. The Minimum Transponder Performance and Received Signal Power shall be
those measured or otherwise ascertained where the Customer is complying or
procuring compliance with SCHEDULE II.
E. MEASUREMENT TEST SET-UP AND STANDARD ENGINEERING PRACTICE
The saturated transponder e.i.r.p. and Received Signal Power is measured
under all weather conditions at the SES Satellite Control Facility in
Betzdorf, Luxembourg. The measured e.i.r.p. for the Customer's Transponder
is kept on record.
In order to accurately determine each transponder e.i.r.p., a measurement
set-up consisting of a calibrated fluxmeter and radiometer is used. The
fluxmeter measures the power flux density at earth surface created by each
individual satellite transponder.
The radiometer measures atmospheric attenuation along the satellite path,
assuming the atmosphere to be an absorbing homogeneous medium at a constant
temperature. Atmospheric attenuation is measured at the beginning of each
e.i.r.p. measurement cycle.
The fluxmeter uses a calibrated antenna, with a calibrated RF measurement
subsystem comprising, among others, a LNA, a down converter and a true RMS
power sensor. A 33 MHz selectivity bandpass filter is used to reduce errors
due to adjacent channel interference during e.i.r.p. measurements.

SCHEDULE VII: PRIORITY AND PRE-EMPTION
A - CUSTOMER STATUS
The Customer shall have the status of: Non-pre-emptible Customer as defined in
Part B below.
B - CATEGORIES OF USE
SES' customers using the ASTRA satellite system shall be accorded (for each
transponder used) priority status as: Protected, Non-Pre-emptible or
Pre-emptible.
1. Protected Customers:
a. will not be subject to pre-emption by other customers;
b. will be entitled to be provided with the use of a back-up transponder
(this will require the pre-emption of Pre-emptible Customer); and
c. shall have the benefit of Spare TWTAs, in preference to certain other
customers, as set out in PART C below.
2. Non-Pre-emptible Customers:
a. will not be subject to pre-emption themselves;
b. will have no rights of pre-emption themselves; and
c. shall have the benefit of Spare TWTAs as set out in PART C below.
3. Pre-emptible Customers:
a. have no rights of pre-emption themselves;
b. may have their transponder pre-empted, as set out in PART D below, in
order to provide a back-up transponder to a Protected Customer; and
c. shall have the benefit of Spare TWTAs, but subject to the rights of
other customers in this Schedule, as set out in PART C below.
C. PRIORITY RULES FOR SPARE TWTAs
As a general rule, Spare TWTAs on the Satellite will be provided on a first
failed/first served basis.
However, in the event of simultaneous transponder failures (or where the
sequences of failures cannot be determined) on the Satellite, and if the number
of failures exceeds the number of available Spare TWTAs, then the following
rules shall apply:
1. Protected Customers have priority over Non-Pre-emptible Customers who, in
turn, have priority over Pre-emptible Customers.
2. Where, pursuant to this Schedule, conflicting rights to Spare TWTAs arise
between customers with the same priority status, priority shall be given in
accordance with the following rules:
26
CONFIDENTIAL
a. customers whose service starts on the Operational Service Date ("OSD
Customer") shall have priority over those whose service starts at a
date after such Operational Service Date;
b. between OSD Customers, priority shall be determined by reference to
the expiry dates of their contracts so that the customers with the
later dates of expiry have priority over customers with earlier expiry
dates;
c. between OSD Customers whose contracts expire on the same date,
priority shall be determined by reference to the dates on which they
signed contracts for the use of a transponder, so that the customers
who signed earlier have priority over those who signed later;
d. between customers whose services start after the Operational Service
Date ("POST OSD CUSTOMERS"), priority shall be determined by
reference to the customer start dates, so that the customers with
earlier customer start dates shall have priority over customers with
later customer start dates;
e. between Post OSD Customers who have the same customer start dates,
priority shall be determined in the same manner as applicable for OSD
Customers under PARAGRAPH 2(b) AND (c) above; and
f. between customers originating from different satellites (i.e.
customers whose initial transponder was located on an ASTRA satellite
other than the Satellite), priority shall be determined by reference
to their respective start date on their respective initial satellite,
so that the customers with earlier customer start dates shall have
priority over customers with later customer start dates.
3. For the purpose of the above rules, (i) the expiry date of a contract
shall, in case of extension of the contract, refer to the extended expiry
date, and (ii) the customer start date refers to the start date of a
customer's initial service and is not affected by any subsequent change of
the service transmitted under a given customer contract.
D. PRE-EMPTION RULES
1. If PART A above provides that the Customer has the status of Pre-emptible
Customer, then the Customer's Transponder shall be pre-emptible on the
terms set out below.
2. a. SES shall have the right to pre-empt the Customer's Transponder to
provide back-up capacity to restore the service of a Protected
Transponder in respect of which SES is contractually bound to provide
back-up capacity at the time pre-emption occurs and if there is no
Spare TWTA that can be used to restore the Protected Transponder's
service.
b. As used herein, "PROTECTED TRANSPONDER" means the transponder of a
Protected Customer on another ASTRA satellite, to be nominated by SES
and notified by SES to the Customer at any time, the protection of
which directly or indirectly requires the pre-emption of the
Customer's Transponder. There may be several Protected Transponders
nominated by SES, provided that each is on a different ASTRA
satellite. SES may increase or reduce the number of Protected
Transponders at any time by giving prior written notice to the
Customer.
3. To Pre-empt the Customer's Transponder:
a. SES will give the Customer at least 24 hours advance warning (by fax
or phone) of
27
CONFIDENTIAL
such pre-emption save in the event of consecutive failures of a
Protected Transponder, in which case such pre-emption warning may be
shorter, it being understood that SES will keep the Customer informed
of the status of the Protected Transponders affected by such
consecutive failures; and
b. at the expiry of the aforementioned advance warning, SES shall have
the right to forthwith interrupt the transmission of all video and
audio services using the Customer's Transponder and the Customer shall
therefore forthwith, upon SES' request, interrupt the transmission of
the Customer Uplink Signal. SES shall in addition have the right to
interrupt the reception of the Customer Uplink Signals by the
Customer's Transponder.
4. The Customer shall comply diligently with SES' instructions for the purpose
of implementing the pre-emption and shall require the operator of the
Uplink Facilities to do the same.
5. a. If SES pre-empts the Customer's Transponder, then, at that time, SES'
obligation to provide the use of the Customer's Transponder, and the
Customer's obligation to pay the corresponding charge, shall be
suspended. The Agreement shall terminate 30 days after the pre-emption
date unless SES, within this period, restores the Protected
Transponder in respect of which pre-emption was implemented. If such
restoration occurs after this 30 days period, then SES shall offer the
Customer's Transponder back to the Customer on the terms set out in
this Agreement for the outstanding period of Term. The Customer shall
have fifteen (15) days to accept SES' offer.
b. Upon termination of the Agreement pursuant hereto, as the case may be,
i. SES shall refund to the Customer the pro rata temporis portion of
the advance payments made by the Customer pursuant to SCHEDULE VI
and relating to the unexpired portion of the period (in respect
of which the Customer has paid in advance) in progress on the
date of pre-emption; or
ii. the Customer shall pay to SES all outstanding sums owed to SES at
the time of termination.
6. a. The Customer shall fully cooperate with SES for the exercise, by SES,
of its right of pre-emption provided herein and shall not raise any
objection, initiate any legal proceedings against SES or the Protected
Customer benefiting from the pre-emption, or take other steps, to
prevent, delay or obstruct the exercise of this right and the Customer
shall be liable for all damages suffered by SES or such Protected
Customer in connection therewith.
b. The Customer shall not make any claim against SES or the Protected
Customer benefiting from the pre-emption in connection with the
exercise, by SES, of its right of pre-emption and shall indemnify SES
against any related third party claim.

II
1. INTRODUCTION
In order to access an ASTRA satellite, approval must first be obtained from
Societe Europeenne des Satellites - SES. The purpose of this approval is to
control the technical parameters of the Uplink Facilities and Customer's Uplink
Signal, to ensure that the following objectives are met:
-- The desired signal quality and availability are achieved;
-- Harmful interference is not produced in the other transmissions carried by
any ASTRA spacecraft;
-- The interference produced in other satellite systems will not exceed the
coordinated levels.
This document outlines the specifications established by SES in order to
achieve those objectives. Access to a specific ASTRA satellite will only be
granted after compliance to the specifications has been demonstrated to the
satisfaction of SES.
In case of contradiction between the ASTRA Access Agreement and the Customer's
Transponder Agreement, the latter shall prevail.
The following definitions are utilised in this document:
OPERATOR -- Person, firm, corporation or other legal entity using an ASTRA
transponder.
SATELLITE CONTROL FACILITY (SCF) -- SES earth station complex located at
Betzdorf, Grand Duchy of Luxembourg.
DIGITAL TRANSMISSION FACILITY (DTF) -- Part of the SES earth station complex,
located at Betzdorf, Grand Duchy of Luxembourg, in which digital services are
handled.
ANALOGUE NETWORK OPERATIONS CENTRE (NOC) -- The monitor and control centre for
all analogue ASTRA services, located at the SCF. This provides a 24 hour
monitor and control network reporting point for service quality monitoring and
problem resolution for the ASTRA analogue satellites.
DIGITAL NETWORK OPERATIONS CENTRE (DINO) -- The monitor and control centre for
all ASTRA digital services, located at the DTF. This provides a 24 hour monitor
and control network reporting point for service quality monitoring and problem
resolution for the ASTRA digital satellites.
REFERENCE STANDARD EARTH STATION (RSES) -- These stations are highly maintained
up- and downlinks to be used in developing baseline performance standards for
transmission carried by the ASTRA satellites.

2.1. GENERAL
A dedicated antenna system shall be used for access to any ASTRA satellite.
Simultaneous access to two or more ASTRA satellites by a single antenna system
is not permitted, but it is permitted for one antenna to access a single
spacecraft in both the FSS and BSS bands. By using a dedicated antenna system
as specified herein for a given ASTRA satellite, link performance in terms of
uplink and downlink Carrier/Thermal Noise (C/N) and Carrier/Cross Polar
Interference (C/X) can be maintained.
2.2. FREQUENCY RANGE
The antenna system is required to meet all the specifications set in the next
items operating in the appropriate FSS or BSS frequency range.
The uplink frequency ranges for the different ASTRA satellites (primary and
back-up bands) are shown in the following Table 2.

2.4. POLARISATION
The ASTRA satellites employ dual linear orthogonal polarisation. The antenna
polarisation angle will be set with SES during service line-up, following the
appropriate procedure established by the NOC and the DINO. The cross-polarised
signal component transmitted by the antenna shall be as specified below:
FSS band: 30 dB
BSS band: 35 dB
2.5. MOTORISATION, ANTENNA POINTING AND TRACKING
Permanent uplink antennas shall be motorised in both azimuth and elevation to
enable rapid repointing in case of necessity, and to facilitate accurate antenna
pattern measurements.
Further, the utilisation of a suitable tracking system is recommended in order
to meet the e.i.r.p. stability requirement specified in the following section
3.2. The tracking system design shall be based on the ASTRA satellite station
keeping and beacon frequency parameters, which are presented in sections 8 and 9

3. RF EQUIPMENT
The RF equipment, including any redundant equipment, is required to meet all
the specifications set out in the following sections 3.1 to 3.6.
3.1. FREQUENCY RANGE AND AGILITY
It shall be possible to set the carrier centre frequency to within +/- 125 kHz.
3.2. e.i.r.p. CAPABILITY
The e.i.r.p. will be established by SES based on the utilised channel and on
the uplink geographical location.
It is expected that SES may request changes in the earth station e.i.r.p.
during the course of the contract, to account for changes in the transponder
performance over its lifetime, utilisation of redundant units or utilisation of
a different transponder.
The uplink e.i.r.p. stability shall be equal to or better than +/- 0.5 dB
including antenna pointing and tracking errors.
Means shall be provided to allow adjustment of the carrier level to within
0.5 dB of the specified value.
3.3. TRANSMITTER INHIBIT
Operators accessing ASTRA satellites may be required by the NOC or the DINO to
shut down a transmission in the case where it is producing harmful interference
into other transmissions. Shut down of a transmission may also be required to
allow the switching into operation of redundant units in the satellite.
In order to comply with this requirement, the Operator shall provide continuous
manning of the uplink site or a remote control system to another location which
will be manned continuously.
The transmitter shall utilise a system which automatically inhibits the
transmission of a chain upon the detection of failure conditions such as loss of
phase lock on an upconverter or excessive HPA transmit power. This system may
also be designed to, alternatively, switch the transmission to a stand-by chain.

14.50, and 17.30 - 18.10 GHz bands, resulting from spurious output, must not
exceed 4.0 dBW/4 kHz;
-- The out-of-band on-axis e.i.r.p. emissions in the 12.75 - 13.25, 13.75 -
14.50, AND 17.30 - 18.10 GHz bands, resulting from intermodulation
products, must not exceed 12.0 dBW/4 kHz.
3.5. OFF-AXIS e.i.r.p. DENSITY
This parameter has a direct impact on the interference produced in other
satellite systems. In order to keep this interference within acceptable levels,
the earth station must comply with the following e.i.r.p. limits. The off-axis
angle, (-), is referred to the main lobe axis, in degrees.
For the frequency range 14.00-14.50 GHz, based on ITU-R Report 1001:
35 - 25log (-) dBW/40 kHz for 2.5 degrees </- (-) </- 48 degrees
-7 - dBW/40 kHz for 48 degrees < (-) </- 180 degrees
For the frequency range 12.75 - 13.25 GHz based on the ITU Appendix 30B planned
limits (averaged over the necessary bandwidth of 26 MHz):
-25 - 25log (-) dBW/Hz for 0.5 degrees </- (-) </- 36.3 degrees
-64 dBW/Hz for 36.3 < (-) </- 180 degrees
For the frequency range 13.75 - 14.00 GHz, the antenna must fully comply with
the antenna specification (section 2.3).
For the frequency range 17.30 - 18.10 GHz, the input power to the antenna
shall not exceed 30 dBW in a single transponder, and the antenna must conform
fully with the antenna specification (section 2.3).
3.6. FREQUENCY STABILITY

specific parts of the NIT can be modified/updated at any time.
A MULTIPLEX DIAGNOSTIC TABLE (MDT) has been defined to provide a mechanism for
conveying diagnostic information about the consistency of all multiplexes to the
central Network Operations Centre at Betzdorf.
The local uplinks should generate such MDT in the case a service failure occurs
for longer than 10 seconds, i.e. if a service component (video, audio, subtitle
or accompanied data) or a Service Information component (NIT, SDT, EIT or TDT)
is missing.
This involves that the local encoders signal corresponding failure information
to the local multiplex controller that shall generate the MDT. After the
failure has been eliminated, the local uplink stops transmitting the MDT.
Details on the Multiplex Diagnostic Table concept can be found in Annex 1.
In addition it is recommended that a transmitted SERVICE DESCRIPTION TABLE (SDT)
includes the service information about all services on the respective
transponder on which it is transmitted, and that an EVENT INFORMATION TABLE
(EIT) includes the event information about all present and following events for
all services on the respective transponder.
6.6. SOURCE CODING
Source coding of video and audio signals shall conform to the following
specifications:
ISO/IEC 13818-2/-3
Generic coding of moving pictures and associated audio (Part 2: Video and
Part 3: Audio).
ETR 154
Digital broadcasting systems for television; Implementation guidelines for
the use of MPEG-2 systems; Video and audio in satellite and cable
broadcasting applications.

7. ASTRA SATELLITE INFORMATION
7.1. ASTRA 1 SERIES
Presently, there are six ASTRA satellites (ASTRA 1A to 1F) at the orbital
position of 19.2 degrees East. In the middle of 1997, ASTRA 1G will be added to
fill the available frequency spectrum at 19.2 degrees East. ASTRA 1G is SES'
seventh satellite to be co-positioned at 19.2 degrees East. Adding 16
transponders, the spacecraft will increase the digital transmission capacity on
that position to 120 transponders.
The eight satellite at the 19.2 degrees East orbital position, ASTRA 1H will be
launched to provide backup capability for the other satellites at that position.
7.1.1 ASTRA 1 TRANSPONDER FREQUENCY PLAN
Figures 7.1.a. to 7.1.g. present the ASTRA 1 satellite system frequency plans.
All transponders are linearly polarised, utilising the polarisation scheme
presented in Table 7.1. The two polarisations are orthogonal to each other and
the horizontal polarisation has a counter-clockwise rotation of 7.5 degrees
relative to the orbit plane, as viewed from the satellite.

7.2. ASTRA 2 SERIES
As of autumn 1997, a second orbital position at 28.2 degrees East will be
activated with the deployment of ASTRA 2A. A second satellite, ASTRA 2B, will be
co-located at 28.2 degrees East in late 1998.
ASTRA 2A will have 28 active Ku-band transponders (32 for the first five years)
operating in the Broadcast Satellite Services frequency band (11.70 - 12.50
GHz), powered by 100 Watt travelling-wave tube amplifiers.
ASTRA 2B will provide up to 28 highpower Ku-band transponders (30 for the first
five years) with an output of 108 Watt each. All transponders can operate over
Europe and a steerable antenna offers the capability for up to 16 transponders
in 12.50 - 12.75 GHz frequency range to be activated within any area of the
earth visible from 28.2 degrees East.
Co-located at 28.2 degrees East, the two spacecraft will provide SES with a
total of 56 transponders in the frequency range 11.70 - 12.75 GHz for digital
broadcast at the second ASTRA orbital position.

9.1. ASTRA 1A AND ASTRA 1B BEACON DETAILS
The following characteristics apply to both ASTRA 1A and ASTRA 1B.
PCM Telemetry: Phase modulation of beacon carrier by PCM (Biphase L)
telemetry to a peak deviation of 1.0+/-0.1 radians. Data
rate is 1 kbits/s.
Analog Telemetry: Phase modulation of beacon carrier by frequency modulated
14.5 kHz subcarrier to a peak deviation of 1.0+/-0.1
radians.

Ranging + PCM Phase modulation of beacon carrier by composite ranging
Telemetry signals at 19 kHz or 27.777 kHz together with PCM telemetry
data signal to a peak deviation of 1.0+/-0.1 radians. In
absence of ranging signals, the deviation of PCM data alone
is 0.5+/-0.05 radians.
There are four ranging tones. The first three ranging tones at 35.43 Hz, 283.45
Hz and 3968.25 Hz serially frequency modulate the 19 kHz subcarrier. The fourth
ranging tone is at 27.777 kHz.
9.2. ASTRA 1C, 1D, 1E, 1F, 1G, 1H AND 2A BEACON DETAILS
The following characteristics apply to the beacons on ASTRA 1C, 1D, 1E, 1F, 1G,
1H and 2A.
During PCM-mode, the beacon is phase modulated (PM) by a telemetry subcarrier
with a subcarrier frequency of 32 kHz and a modulation index of 1.25+/-0.15
radians. The subcarrier is biphase modulated by telemetry data.
During range mode, the 32 kHz subcarrier is switched off and the beacon is phase
modulated by sequences of 4 ranging tones with a modulation index of 1.00+/-0.15
radians.
9.4. ASTRA 2B BEACON DETAILS
The following characteristics apply to the beacons on ASTRA 2B.
During PCM mode, the beacon is phase modulated (PM) by a telemetry subcarrier
with a subcarrier frequency of 32 kHz and a peak modulation index of 1.5

During ranging mode, the 32 kHz subcarrier is switched off and the beacon is
phase modulated by a ranging tone, which itself is modulated by an ambiguity
resolution code. The peak modulation index during ranging is 0.7 radians.
During simultaneous PCM and ranging on the TM downlink signal, the
PCM-modulated 32 kHz subcarrier and ranging tone are combined into one baseband
signal, which modulates the main carrier with max. effective modulation indices
of 1.4 radians for the PCM-signal and 0.4 radians for the ranging tone.

MULTIPLEX DIAGNOSTIC TABLE (MDT)
1 INTRODUCTION
In a digital broadcast environment with a multitude of services there is a need
for highly automated means to monitor and subsequently to provide information
(e.g. failure messages) about the availability of services as well as of service
components such as video, audio and subtitling and of Service Information
tables.
In order to support the detection of service failures, to provide information
for remedial measures and to efficiently log such events, a transport mechanism,
the Multiplex Diagnostic Table (MDT) has been defined. This system will serve
for conveying diagnostic information about the consistency of all DVB/MPEG-2
multiplexes on ASTRA to the central Digital Network Operations Centre (DINO) of
Societe Europeenne des Satellites (SES).
2 FUNCTIONALITY
MDTs can be generated at any point in the transmission chain to signal missing
streams (e.g. video, audio, subtitle or accompanied data) or Service Information
components (e.g. NIT, SDT, EIT or TDT) within a multiplex. As the underlying
concept of the MDT system is to detect and signal failures at the point where
they are generated, the system supervisor of the DVB/MPEG-2 encoding,
multiplexing and modulation equipment should monitor the correct functioning of
all equipment modules and should generate an MDT in the case a service failure
occurs for longer than 10 seconds.
MDTs shall then be periodically transmitted every 10 seconds until the failure
is fixed. In addition to faulty equipment modules also missing input streams can
be identified by subsequent modules in the transmission chain which then
generate corresponding MDTs.
This principle will be applied e.g. by the special monitor IRDs of the DINO
which can not only receive and extract incoming MDTs from the multiplexes but
also can generate MDTs in the case e.g. Service Information components are
missing. All MDTs are being fed via the ASTRA Service Information Update System
(ASIUS) into the Service Availability System (SAS) of the Digital Network
Operations Centre. Upon reception of an MDT an alert is initiated by the DINO
computer system which then enables the operator to act appropriately based on
detailed transponder specific diagnostic information provided together with the
alert message.

3 SYNTAX OF THE MULTIPLEX DIAGNOSTIC TABLE (MDT)
The syntax of the MDT is conforming to the one defined in the standard ISO/IEC
13818-1 for the definition of private sections.
As defined in that standard, private data may be sent in transport stream
packets with PID not listed in the Program Map Table sections.
Therefore, Multiplex Diagnostic Tables shall be carried on PID 0x1FFD using the
normal payload unit start indicator/pointer field mechanism described in the
standard ISO/IEC 13818-1. This PID shall not be used for any other purpose on
the ASTRA Satellite network. A MDT must be inserted in maximum one Transport
Stream Packet resulting in a maximum table size of 184 bytes.

following the section length field. The section length shall not exceed
181 bytes so that the entire section has a maximum length of 184 bytes.
TRANSPORT STREAM ID: This is a 16 fit field which serves as a label to identify
the transport stream where the error or warning has occurred.
-------------------------------------------------------------------------------

39
ORIGINAL NETWORK ID: This 16 bit field gives the label identifying the
net work id of the originating delivery system of the transport stream where the
error or warning has occurred.
MDT VERSION NUMBER: This 4 bit field identifies the version number of the MDT
structure. Currently, the MDT version number shall be set to "0".
FAULT SOURCE: This is a code that, together with the transport stream id and the
original network id, identifies the origin of the failure. Fault source values
can be defined by the operator of the transport stream within the ranges defined
in Table 1.
FAULT TYPE: This 16 bit field identifies the basic type of errors or warnings.
Only values described in Table 2 are defined. In every MDT section only one
Fault type shall be listed resulting in only one basic type of error or warning
per MDT.
FAULT MAJOR: This 16 bit field provides more detailed information about the
errors or warnings as defined by the Fault type. Depending on the value of the
Fault type, the Fault major has different meanings. Currently, only the values
given in Table 4 and 5 are defined. If for a Fault type no Fault major code is
defined, the loop within the MDT shall be empty. If for a Fault type several
Fault major codes are defined the loop may contain more than one of these codes.
In case of missing components of a service (Fault type = 0x0100) the Fault major
code is equal to the service id of this service.
FAULT MINOR: This field provides additional information about the error or
warning as described by the combination of Fault type and Fault major. If no
Fault minor code is defined for a Fault major code, the Fault minor field shall
be present and all bits shall be set to "1". For the time being Fault minor is
only defined for Fault type = 0x0100 (Component of service missing) as described
in Table 3. In that case the service id of the service comprising the missing
component is defined in the Fault major field and the missing component is
defined in the Fault minor field.

1 INTRODUCTION
Service information (SI) systems for Digital Video Broadcast are considered by
broadcasters and also by network operators as one of the crucial elements in
digital transmission of video, audio and data signals. With the plethora of
services being available in the digital age, an effective means of guiding
consumers around the various services on offer is an essential pre-requisite of
any consumer oriented digital transmission and reception system. Beyond
informing about the available services, there is also a need to allow for the
quick acquisition of any service that can be received.
Based on the DVB SI specification Societe Europeenne des Satellites (SES) has
developed the ASTRA Service Information Update System (ASIUS) for providing
tuning information and also for informing the digital IRDs about all services on
the ASTRA network. In addition ASIUS monitors the Service Information on all
transponders, checks the presence and the correctness of this data and provides
also diagnostics information on the consistency of the multiplexes.
2 CONCEPT OF THE ASTRA SERVICE INFORMATION UPDATE SYSTEM
The ASTRA Service Information Update System (ASIUS) is an application of the DVB
Service Information specification as standardised in ETS 300468/1/ and may serve
the Digital Satellite IRD to quickly tune to the receivable services on ASTRA.
It also enables the presentation of services and broadcasters in a convenient
way to the consumer.
This is achieved by compiling and transmitting an ASTRA Network Information
Table (ASTRA NIT) providing tuning information as well as an ASTRA Service
Description Table (ASTRA SDT) containing information about all services on all
transponders on the ASTRA network. Thus the IRD is enabled to present the names
of all services on ASTRA, the names of all corresponding broadcasters (service
providers) and the service types such as TV, Radio, Teletext or data services,
without having to tune to each transponder.
The concept for the ASIUS involves the transmission of the ASTRA NIT on each
transponder. This NIT conveys information about the physical parameters of all
multiplexes on ASTRA (frequency, symbol rate, etc.) as well as the information
about the network itself (ID, name, satellite position).
Furthermore, the concept involves the transmission of the ASTRA SDT on two ASTRA
Service Information channels (Barker Channels), one with horizontal and one with
vertical polarization.

As it is the objective to provide up-to-date network information and service
description data about all transponders on ASTRA, a concept for an automatic
updating of the ASTRA NIT/SDT has been developed, considering all updates from
the Betzdorf earth station as well as the remote uplinks.
The ASTRA NIT is mainly under the administration of SES (network operator)
except for parts as e.g. the Forward Error Correction (FEC) scheme which may be
adjusted by the remote uplink operators.
The multiplex specific SDTs are under the administration of the broadcasters.
ASIUS receives the SDTs transmitted on all transponders, extracts those parts
directly related to each respective transponder and compiles an ASTRA SDT with
service description information (e.g. service names, service providers,
service types) about all services on ASTRA.
[FIGURE 182]

SES-ASIUS CONFIDENTIAL
SYE-045/12-96

The process of updating the ASTRA NIT and ASTRA SDT is illustrated in Figure 1.
The process involves the following steps:
1. The ASTRA NIT can be received at all remote uplink sections outside
Betzdorf and can then be inserted into the remotely uplinked multiplexes.
The ASTRA SDT is transmitted on two transponders (one with horizontal, one
with vertical polarization) from Betzdorf and therefore does not have to be
received/inserted at the remote uplinks.
2. Any remote uplink operator can at any time update the information in the
NIT related to his remote uplink (i.e. change the FEC scheme of his
transponder and/or add a service list descriptor) and/or the corresponding
service description data in the SDT and insert the data into the remote
multiplex.
3. At Betzdorf, the NIT/SDT processing system performs the following tasks:
a) receive all Transport Streams of ASTRA,
b) extract those parts of the NITs and SDTs which have been altered by
the remote uplinks,
c) compile this update information to generate new versions of the
ASTRA NIT and SDT,
d) insert the updated ASTRA NIT into all multiplexes uplinked from
Betzdorf,
e) insert the updated ASTRA SDT into the multiplexes carrying the
ASTRA Service Information channels.
4. The remote uplinks again can receive this updated ASTRA NIT and insert the
data into the remotely uplinked multiplexes.
After step 3, a complete update process of the ASTRA NIT and ASTRA SDT is
performed. The update process is continuously repeated. Thus, all remotely
mastered updates are almost immediately available in the ASTRA NIT/SDT.
The update process for the ASTRA NIT/SDT is stable since for each part of the
data there is only one master uplink assigned which is allowed to edit updates.
Other uplinks are slaves concerning the data mastered by a specific up-link
operator and therefore only insert the received updated data into their own
remote up-link.
The interconnection between ASIUS and other equipment of the Digital Network
Operations Centre (DINO) at Betzdorf is illustrated in Figure 2.

3. FUNCTIONAL FEATURES OF ASIUS
3.1 SI DATA STRUCTURES CONSIDERED BY ASIUS
Regarding the various tables defined by MPEG-2 and by the DVB project, there are
only a few relevant for the ASIUS. These are the Network Information Table, the
Service Description Table, the Event Information Table (EIT), and the Time and
Date Table (TDT).
3.1.1 NETWORK INFORMATION TABLE (NIT)
The structure of the Network Information Table is presented in Figure 3. The
ASTRA NIT is divided in sections according to the MPEG-2 syntax. Each section
includes a loop over network related descriptors which is used for conveying the
network name descriptor and the linkage descriptors to the ASTRA Service
Information channel.
For each transport stream the NIT contains a loop over transport stream related
descriptors including the satellite delivery system descriptor with information
such as frequency, polarisation, modulation, symbol rate and FEC scheme.
Conveying an optional service list descriptor in that loop of the NIT is not
considered by ASIUS.
3.1.2 ASTRA SERVICE DESCRIPTION TABLE (SDT)
The structure of the Service Description Table is illustrated in Figure 4. The
ASTRA SDT is also divided into sections according to the MPEG-2 syntax. For each
Transport Stream at least one section with service description data is
transmitted. All SDT sections include a loop over all services on the
corresponding Transport Stream. For each service a loop of descriptors including
service descriptor and country availability descriptor is conveyed.
NVOD reference descriptor and time shifted service descriptor are also
considered by ASIUS. In order to identify the actual Transport Stream on which
Service Information is received and thus to identify the relevant SI parts that
have been updated at a remote uplink, the corresponding transports stream id can
be found in each header of a service description section for the actual
Transport Stream/1/.

3.1.3. MULTIPLEX DIAGNOSTIC TABLE (MDT)
In a digital broadcast environment with a multitude of services there is a need
for highly automated means to monitor and subsequently to provide information
(e.g. failure messages) about the availability of services as well as of service
components such as video, audio and subtitling and of Service Information
tables.
In order to support the detection of service failures, to provide information
for remedial measures and to efficiently log such events, a transport mechanism,
the Multiplex Diagnostic Table (MDT) has been defined by SES. This system is
serving for conveying diagnostic information about the consistency of all
DVB/MPEG-2 multiplexes on ASTRA to the central DINO in Betzdorf.
MDTs can be generated at any point in the transmission chain to signal missing
streams (e.g. video, audio, subtitle or accompanied data) or Service Information
components (e.g. NIT, SDT, EIT or TDT) within a multiplex. As the underlying
concept of the MDT system is to detect and signal failures at the point where
they are generated, the system supervisor of the DVB/MPEG-2 encoding,
multiplexing and modulation equipment should monitor the correct functioning of
all equipment modules and should generate an MDT in the case a service failure
occurs for longer than 10 seconds.
MDTs shall then be periodically transmitted every 10 seconds until the failure
is fixed. In addition to faulty equipment modules also missing input streams can
be identified by subsequent modules in the transmission chain which then
generate corresponding MDTs.
This principle is applied e.g. by the special monitor IRDs of the DINO which can
not only receive and extract incoming MDTs from the multiplexes but also can
generate MDTs in case e.g. Service Information components are missing. All MDTs
are being fed via the ASIUS into the Service Availability System (SAS) of the
Digital Network Operations Centre. Upon reception of an MDT an alert is
initiated by the DINO computer system which then enables the operator to act
appropriately based on detailed transponder specific diagnostic information
provided together with the alert message.
Details about the MDT concept can be found in Annex 1.
3.2 SI DATA ACQUISITION
The ASTRA Service Information Update System in Betzdorf includes the reception
of all Transport Streams of the ASTRA Satellite System. From these Transport
Streams the relevant SI is extracted and passed over to the ASIUS processing
station. This includes the NIT for the actual network (ASTRA) and the SDT for
the actual Transport Stream. If a MDT has been received (which occurs only in
case of a failure), it will also be transferred
SES-ASIUS CONFIDENTIAL
SYE-045/12-96
06 DECEMBER 1996
9
to ASIUS.
The following processing steps have been implemented in ASIUS for the SI data
acquisition:
1. Reception of the DVB/MPEG-2 Transport Streams from all ASTRA transponders.
2. Extraction of all transponders SI data (NIT, MDT, SDT, EIT, TDT). By means
of the version number mechanism provided in each section syntax, the IRD
considers only the updated parts of this data.
3. Transmission of all the updates from the IRDs to ASIUS. The IRDs
furthermore monitor the availability of the NIT, SDT, EIT and TDT (Time and
Date Table) in each Transport Stream and shall generate a Multiplex
Diagnostic Table and transmit it to the ASIUS processor, if a failure is
detected.
3.3 SI DATA PROCESSING AND MONITORING
After having received an update the ASIUS compiles a new version of the ASTRA
NIT and ASTRA SDT. Since the system has immediate access to all SI data on the
ASTRA network it monitors the presence, correctness, and also the consistency of
the SI data. In case of an erroneous situation an alarm is triggered and the
operators in the DINO are informed.
3.4 SI DATA DISTRIBUTION
After the compilation of the received SI data by the ASIUS processor, the
updated ASTRA NIT is transmitted on all transponder uplinked from Betzdorf. The
ASTRA SDT is inserted into the two transponders which contain the ASTRA Service
Information channel. In addition a linkage descriptor is inserted in the ASTRA
NIT, which is available on all transponders. This descriptor points to
transport stream ids and service ids of the ASTRA Service Information channels.
If the consumer wants to have access to the ASTRA SDT and IRD will read the
linkage descriptor and tune to one of the corresponding transponders. After the
reading of the ASTRA SDT all services available on the ASTRA Satellite System
could be displayed. It is however assumed that certain filter mechanisms would
be applied to the data before displaying the information in a consumer friendly
way. More details on the functionality of the ASTRA Service Information channel
are described in SES' 'Technical Recommendations for Digital IRDs'/2/. A flow
chart of the access functionality for the ASTRA SDT is depicted in Figure 5.

MULTIPLEX DIAGNOSTIC TABLE (MDT)
1 INTRODUCTION
In a digital broadcast environment with a multitude of services there is a need
for highly automated means to monitor and subsequently to provide information
(e.g. failure messages) about the availability of services as well as of service
components such as video, audio and subtitling and of Service Information
tables.
In order to support the detection of service failures, to provide information
for remedial measures and to efficiently log such events, a transport mechanism,
the Multiplex Diagnostic Table (MDT) has been defined. This system is serving
for conveying diagnostic information about the consistency of all DVB/MPEG-2
multiplexes on ASTRA to the central Digital Network Operations Centre (DINO) of
Societe Europeenne des Satellites (SES).
2 FUNCTIONALITY
MDTs can be generated at any point in the transmission chain to signal missing
streams (e.g. video, audio, subtitle or accompanied data) or Service Information
components (e.g. NIT, SDT, EIT or TDT) within a multiplex. As the underlying
concept of the MDT system is to detect and signal failures at the point where
they are generated, the system supervisor of the DVB/MPEG-2 encoding,
multiplexing and modulation equipment should monitor the correct functioning of
all equipment modules and should generate an MDT in the case a service failure
occurs for longer than 10 seconds.
MDTs shall then be periodically transmitted every 10 seconds until the failure
is fixed. In addition to faulty equipment modules also missing input streams can
be identified by subsequent modules in the transmission chain which then
generate corresponding MDTs.
This principle is applied e.g. by the special monitor IRDs of the DINO which can
not only receive and extract incoming MDTs from the multiplexes but also can
generate MDTs in the case e.g. Service Information components are missing. All
MDTs are being fed via the ASTRA Service Information Update System (ASIUS) into
the Service Availability System (SAS) of the Digital Network Operations Centre.
Upon reception of an MDT an alert is initiated by the DINO computer system which
then enables the operator to act

appropriately based on detailed transponder specific diagnostic information
provided together with the alert message.
3 SYNTAX OF THE MULTIPLEX DIAGNOSTIC TABLE (MDT)
The syntax of the MDT is conforming to the one defined in the standard ISO/IEC
13818-1 for the definition of private sections.
As defined in that standard, private data may be sent in Transport Stream
packets with PID not listed in the Program Map Table sections.
Therefore, Multiplex Diagnostic Tables shall be carried on PID 0x1FFD using the
normal payload unit start indicator/pointer field mechanism described in the
standard ISO/IEC 13818-1. This PID shall not be used for any other purpose on
the ASTRA Satellite Network. A MDT must be inserted in maximum one Transport
Stream Packet resulting in a maximum table size of 184 bytes.

TRANSPORT STREAM ID: This is a 16 bit field which serves as a label to identify
the Transport Stream where the error or warning has occurred.
ORIGINAL NETWORK ID: This 16 bit field gives the label identifying the
network id of the originating delivery system of the Transport Stream where the
error or warning has occurred.
MDT VERSION NUMBER: This 4 bit field identifies the version number of the MDT
structure. Currently, the MDT version number shall be set to "0".
FAULT SOURCE: This is a code that, together with the transport stream id and the
original network id, identifies the origin of the failure. Fault source values
can be defined by the operator of the Transport Stream within the ranges defined
in Table 1.
FAULT TYPE: This 16 bit field identifies the basic type of errors or warnings.
Only values described in Table 2 are defined. In every MDT section only one
Fault type shall be listed resulting in only one basic type of error or warning
per MDT.
FAULT MAJOR: This 16 bit field provides more detailed information about the
errors or warnings as defined by the Fault type. Depending on the value of the
Fault type. the Fault major has different meanings. Currently, only the values
given in Table 4 and 5 are defined. If for a Fault type no Fault major code is
defined, the loop within the MDT shall be empty. If for a Fault type several
Fault major codes are defined the loop may contain more than one of these codes.
In case of missing components of a service (Fault type = 0x0100) the Fault major
code is equal to the service id of this service.
FAULT MINOR: This field provides additional information about the error or
warning as described by the combination of Fault type and Fault major. If no
Fault minor code is defined for a Fault major code, the Fault minor field shall
be present and all bits shall be set to "1". For the time being Fault minor is
only defined for Fault type = 0x0100 (Component of service missing) as
described in Table 3. In that case the service id of the service comprising the
missing component is defined in the Fault major field and the missing component
is defined in the Fault minor field.
