ELECTRICAL SAFETY

: GENERAL RULES

Carefully observe the speciﬁ

c procedures for installation, turnup, and mainte-

nance where AC or DC power is present and observe the following general infor-

mation/rules.

• Remove rings, watches, and other metal jewelry. Short circuits in low-voltage, low-

impedance DC circuits can cause severe arcing that my result in burns or eye

injury. Exercise caution to avoid shorting power input terminals.

•

This equipment is intended for installation in a RESTRICTED ACCESS

LOCATION ONLY.

•

Installation and maintenance are to be performed only by technically qualiﬁed

professional personnel.

ATIC ELECTRICITY

When the above symbol or letters are displayed, observe special precautions.

An electrostatic-sensitive device can be weakened, damaged or destroyed even by a

minute discharge that would even go unnoticed by a technician.

Common plastics, clothing, and paper or cardboard are the most common sources of

static charges.

Common plastic, white foam, cellophane and masking adhesive tapes must not come

in contact with ESS devices or their packaging.

MODULE HANDLING

To minimize risk of damage to an ESS device:

• All modules should be handled as static sensitive devices

• Heel straps are only effective while standing on conductive or static dissipative

surfaces

• Ground straps, either wrist (PN 055-9357-010) or heel (PN 055-9357-020), should

be worn prior to and while touching or handling modules containing ESS devices.

• Surfaces (with resistance to ground in excess of 100 Meg-ohms), such as ordinary

tile, should be covered with properly grounded static dissipative runners or waxed

with a static dissipative wax (PN 057-4000-006)

• Modules (even temporarily) should be stored, packed, or shipped in antistatic bags

or containers

• Do not handle modules by touching the electrical components and circuit board.

Use the plastic handle or other outside casing

• Use only ESS rated cleaning devices to clean modules

• Be sure to handle failed modules with the same precautions as good modules

INTRODUCTION

The Terrestrial Satellite Repeater is a modular solid-state device that receives audio/

video multiplexed data transmissions via a SIRIUS Satellite. The repeater then pro-

cesses the received

data and retransmits it through tower mounted antennas to end

users’

receivers.

Figure 1 - 1 is a simpliﬁed diagram of a SIRIUS Terrestrial Repeater broadcast system.

A repeater site (part of the broadcast system) includes a Very Small Aperture Termi-

nal (VSAT) antenna with a Low Noise Block converter (LNB) attached, a Global

Positioning System (GPS) antenna, a repeater unit, and tower mounted transmitting

antennas.

The repeater site interfaces to a SIRIUS Network Management Center (NMC) via

TELCO lines to monitor repeater operational status.

2.1

GENERAL

This section presents a functional description of the Sirius Terrestrial Repeater.

2.2

SYSTEM FUNCTIONAL OVERVIEW

Figure 2 - 1

shows the basic Repeater Simpliﬁed Functional Block Diagram.

The Sirius Terrestrial Repeater transmits at the 2.3265 GHz frequency with a 4.012

MHz signal bandwidth. Refer to the tables in Section 1 for the technical characteris-

tics and the major components.

2.2.1

SIGNAL FLOW

The Sirius Terrestrial Repeater receives the video/audio Complex Digital Data

Stream (CDDS) signal in a TDM format at the KuBand from the satellite by means

of a Very Small Aperture Terminal (VSAT) parabolic antenna.

The CDDS signal passes through a Low Noise Block (LNB) converter to the DVB-S

L-Band satellite receiver; an integral part of the Signal Processing Unit (SPU). The

satellite receiver demodulates the incoming stream and outputs the processed data

via the Asynchronous serial Interface (ASI) to the SIRIUS modulator stage.

The output of the modulator is an Orthogonal Frequency Division Multiplexed IF

(I and Q signals).

The IF is up-converted to an S-band frequency for insertion into the High Power

Ampliﬁer (HPA). The output of the HPA goes through the output bandpass ﬁlter

(BPF) where “out of band” generated signals are removed.

The output BPF signal (200W RF) goes through the output RF coupler to the tower

mounted antennas and is transmitted to the end user

MAIN FUNCTIONS

The Sirius Terrestrial Repeater consists of the following main functions:

•

Receiver

– Receives the down converted input signal from the VSAT Antenna/

LBN via coax cable. Processes the received signal for transmission to the modula-

tor.

•

Transmitter

– (modulator, up converter, HPA, bandpass ﬁlter, and output

coupler) Transmits the received and processed RF signal, via tower mounted

antenna, to the end user’s equipment.

•

Timing

– A GPS receiver provides signals for synchronization within the Signal

Processing Unit (SPU).

•

Monitor and Control

– This function is primarily performed by the main con-

troller board which receives information from all external devices, including

temperature, power to antenna, output signal control parameters, and equipment

condition.

•

Power Distribution

– Power is controlled and distributed by a power distribu-

tion unit (PDU) and a relay control group.

Functional description of the components involved in these main functions follows.

2.3.1

SIGNAL PROCESSING UNIT (SPU) SUB-ASSEMBLY

Figure 2 - 2

and

Figure 2 - 3

respectively show a physical representation and functional

block diagram of the SPU.

The primary function of the SPU is to receive the complex digital data stream

(CDDS) from the VSAT satellite, modulate the received signal into a COFDM wave-

form, up-convert the waveform to the assigned S-Band frequency within the user’s

frequency plan, and forward this waveform to the HPA in the transmitter portion of

the repeater.

The SPU contains the L-Band satellite receiver, modulator, up-converter, main con-

troller, and Uninterruptible Power Supply (UPS).

2.3.1.1

L-Band (VSAT) Receiver

The VSAT L-Band receiver connector panel is shown in Figure 2-4.

The receiver module is located on the SPU sub-assembly.

The module receives the DVB-S/S2 signal data stream (which carries the SIRIUS

proprietary CDDS) from the L-band LNB module located on the Ku-band VSAT

antenna.

The receiver processes the down-converted L-band signal by DVB-S/S2 transport

stream removal and data recovery

The ﬁnal receiver output is a stream of CDDS encapsulated into pseudo MPEG TS

packets.

Figure 2 - 4 VSAT (L-Band) Receiver Panel

2.3.1.2

Modulator

The modulator panel is shown in

Figure 2 - 5

The modulator, located on the SPU sub-assembly, converts the digital coded stream

to an IF.

It receives Sirius CDDS stream input data from the L-band receiver in the form of

MPEG TS packets transferred by DVB-ASI.

The modulator also receives reference system clock signals in the form of 10MHz and

1PPs from the GPS distribution ampliﬁers. These clock signals enter the modulator

at J17A and J17B and synchronize the modulator clock and, in turn, the modulator

output.

COFDM converts the MPEG TS frames to an IF in the form of I and Q signals with a

center frequency of 76.25 MHz ready for up conversion.

The modulator contains a DB-9 serial port wired as a DTE device and requires a null

modem cable to communicate with the serial port on a PC.

Up-Converter

Figure 2 - 6 shows the up-converter panel. The up-converter converts the modulator

IF (I and Q channels) output to S-Band.

An up converter controller applies DAC-controlled DC offset to each IF channel,

attenuates and ﬁlters the channels, and then sends them to the up-converter for

S-Band frequency con-version.

The 2.32625 GHz S-Band output of the up-converter feeds into the pre-driver of the

HPA.

SPU Main Controller Board

See Figure 2 - 7 and Figure 2 - 8 connector panel and functional block diagram.

The main controller supports the repeater site operation, conﬁguration, manage-

ment, and status reporting. It manages power-up, power-down and RF control pro-

cesses. The controller provides capability for remote upgrade of repeater software,

and provides local and remote interfacing for all command and status functions

(including digital, thermal, power, and RF performance of the repeater).

Description

Issue 1, March 2008 DTR-0200-SA-SIRIUS

2-11

Control commands for status requests and operating parameter modiﬁcations from

the operator interfaces are received and processed by the main controller.

The controller reports problem conditions through dedicated interfaces and also indi-

cates current status and alarms via front panel LEDs.

Repeater identity can be conﬁgured remotely or locally via the controller. Conﬁgura-

tion includes repeater identity (repeater name, password, local IP address, two

remote NMS IP addresses, and SNMP security variables).

The functional software components of the controller are:

• Repeater protection via continuous local monitoring of all main blocks.

The output coupler, HPA, and HPA power supply are continually monitored. If any

monitored parameter exceeds its threshold, the RF is shut down and the Network

Management Center (NMC) is notiﬁed. Hazardous conditions shut down the

repeater. Under certain conditions clearing the event will automatically restart the

repeater.

• HPA RF output Automatic Power Level Control (APLC).

The APLC loop checks RF output level reported by the RF output coupler and

changes the up converter out-put level.

• Performance of two-way communication with the NMC.

Communication can be via either of the following:

Dial-up modem through a PSTN line

Ethernet to the Management Center via WAN

Forward channel using the input channel and satellite return channel.

• Load, initialize, and monitor the supervisor controller, the GPS receiver, the up

converter, the VSAT receiver, the modem, and the modulator.

• Perform software upgrade for the main controller, supervisor controller, and mod-

ulator.

• Monitor RF subsystems; HPA, HPA power supply, and RF coupler

• Event Logging is written to the EEPROM and accessible from WEB/embedded

FTP server via NMC.

• Self monitoring and environment monitoring (temperature, fans, voltage, cur-

rent)

Power-up Test

– on power-up the main controller performs a self-test (POST) and

waits for all other subsystems to perform POST of their major components and

report results. Any main block problem causes the repeater to shut down and an

attempt is made to notify the NMC. Notiﬁcation is attempted via the modem or

Ethernet to the NMC.

Functiona

Description 3EM21522AAAA

DTR-0200-SA-SIRIUS Issue 1, March 2008

2-12

Back-up Test

– continuous self-monitoring of controller and all subsystems. Anoma-

lies are reported to NMC. Major faults cause the controller to shut down the repeater

Heartbeat

– a special trap/message is transmitted regularly (transmission inter-val

set by user via GUI, See Figure 5-34 in Section 5) to the NMC. This message indi-

cates to the NMC operator that the repeater is alive; a valid connection exists

between the repeater and the NMC, and the repeater main controller is operational.

• Local/remote software upgrade – software upgrade is initiated via a web browser

by directly uploading the upgrade ﬁle to the controller. When the ﬁle is success-

fully received, the web server task will invoke the upgrade procedure. Upgrade

applies to any of the controller software components or any of the other system

components.

• Parameter database clearing in EEPROM will return to default settings.

The functional physical components of the controller are:

• Main Controller microprocessor chip MPC860x

• Supervisor Processor microprocessor chip ATmega2560

• GPS receiver

• Dial-up modem

• Ethernet Switch

• Internal UPS

2.3.1.4.1

Main Controller Microprocessor Chip

The MPC860 microprocessor performs all site management to include control of the

GPS receiver, modem, and L-band DVB-S/S2 receiver. The controller also communi-

cates with the SPU modules and on-board components via dedicated interfaces using

soft-ware deﬁned protocols. The MPC860 chip connects to the Ethernet, to an exter-

nal monitoring/controlling console (PC), to the VSAT receiver, the internal modem, to

the upconverter, to the power ampliﬁer, and to the following front panel components:

the status LED, the Local/Remote switch, and the Reset switch. The MPC860 also

connects, via the module internal I2C bus, to the ATmega256 control processor

(supervisor controller).

• Ethernet connection-via an internal Ethernet controller connected to an internal

Ethernet switch and terminating at four RJ-45 connectors (J115A, J115B, J115C,

and J115D). External Console connection via a UART (UART0) internal to the

MPC860 chip and connected to module internal connector J129 (DB9-F).

• VSAT Receiver- connects to the MPC860 chip via the module internal I2C bus

and internal connector J129.

• Internal Modem connection-from UART2 in the MPC860 chip to the modem and

then to the RJ-11 connector at J119.

• The Upconverter-connected to the MPC860 chip via the module internal I2C bus.

• Power Ampliﬁer connection-to the MPC860 chip via RS485 bus. This is a full

duplex PA control line.

• Front panel components-the status LED, the Local/Remote switch, and the Reset

switch connect to the J129 internal connector on to the I_C bus and into the main

processor chip.

2.3.1.4.2

Supervisor or Control Processor

The ATmega256 chip monitors status, temperature, and RF power. The chip also con-

trols output digital relays required for interface with the external equipment.

• Relay Control – The ATmeg a256 connects to the Relay Control Group via back

panel DB25 connector P18 for fan control (four channels).

• Fan Speed & Door Monitoring – The processor connects to DB25 back panel con-

nector P17A to receive digital inputs (up to 12 lines). Four channels are for fan

speed monitoring, and two for front and back door monitoring. Six additional

switches can be connected as required.

• Temperature Sensing – There are three temperature sensing thermistors (ambi-

ent, HPA compartment and SPU) connected to terminal board 3 (TB3). The pro-

cessor provides +5 VDC to each thermistor and reads the temperature from -55˚C

to + 180˚C of each thermistor. The TB3 connections to the processor are via DB9-

F panel connector P7B.

3EM21522AAAA Functiona

•RF Power: Monitoring is two channel and RS485 full duplex. The path is from the

reﬂected power and forward power detectors through DB9-M panel connector

P6B into the processors UART1 and UART2. The Atmega256 processor initial-

izes the GPS Receiver, makes all necessary settings and then monitors important

stats (refer to GPS Receiver below).

2.3.1.4.3

GPS Receiver

The GPS receiver provides 10 MHz and 1 pps signals for synchronization purposes.

The signals’ exact alignment to a UTC/GPS second is monitored via a message

received by the controller as a response to the correspondent’s request. The receiver

supports proprietary binary messages and also NMEA formatted message protocol.

A subset of the protocols is used by the MPC860 microprocessor to control receiver

operation. After initialization, the GPS starts tracking the satellites to determine its

position; the accuracy of the GPS output signals depends on the GPS satellite recep-

tion. The Controller communicates continuously with the GPS to deter-mine if the

GPS is still operating correctly and still receiving the satellite signals, etc., or if it

has any alarm (malfunction) to report. The output of the GPS (1 pps and 10MHz

pulses) is to the Distribution Ampliﬁers, which in turn feed the pulses to the Modula-

tor and Up-converter via internal connector J130.

2.3.1.4.4

Dial-up Modem

Two chips, Si2457 and Si3018, make up an internal modem and provide the required

connectivity to POTS (PSTN). The phone line connection is via an RJ11connector

(J119 on the front panel). This telephone communication channel provides the main

control interface for repeater monitoring by the Sirius repeater NMS. Information

exchange between site and NMS is via SNMP.

2.3.1.4.5

Ethernet Switch

The Ethernet switch is a built-in 10/100 Base-T switch and provides four RJ-45

Ethernet ports allowing the controller to communicate with other Ethernet devices.

2.3.1.4.6

Uninterruptible Power Supply (UPS)

See

Figure 2 - 9

. The UPS monitors the AC line status and if the AC voltage drops, it

provides +5V and +3.3V for CPU backup. The UPS provides CPU back-up power for

up to 5 minutes, enough time to store the current state of the repeater, store param-

eters in volatile memory, notify NMS, and completely and safely shut down the

repeater. The unit comprises a bank of ﬁve Ultra Capacitors, 350F/2.5V each, a DC/

DC converter, over-voltage protection and charging/discharging circuitry. During

repeater power-up, the capacitors charge through a current limiting resistor with

the bulk of the power going to the SPU and no interruption of power during this

period. When power is interrupted, the capacitors discharge to the load through the

DC/DC converter at a steady ﬁve volts until they reach approximately seven volts at

which time the SPU power is terminated.

Functiona

Description 3EM21522AAAA

DTR-0200-SA-SIRIUS Issue 1, March 2008

A manual ON/OFF control switch is located on the front panel of the UPS and

allows the unit to be manually switched on or off. This is used primarily by mainte-

nance technicians when servicing the repeater.

An internal automatic ON/OFF switch switches the unit off when the +5 or 3.3

input voltages drop. This prevents back current feed to the power supply. The UPS

has a 3-wire interface for connection of an optocoupled AC sensor.

Figure 2 - 9 Uninterruptible Power Supply (UPS)

2.3.1.4.7

SPU Power Supply

The power supply is 208VAC, 30-50 W brick power supply AC/DC converter and pro-

vides all required voltages for the SPU:

+5V @ 3A

+3.3V@1A

+12V@2A

-12V@0.5A

+24V@1A

The power supply input is 208VAC/50-60 Hz.

HIGH POWER AMPLIFIER (HPA)

See

Figure 2 - 10

and

Figure 2 - 11

for the HPA sub-assembly front and rear panels and

the HPA functional block diagram.

The HPA ampliﬁes the S-Band terrestrial signal to an output level of 200 watts

(after the output ﬁlter). The HPA is a solid-state device operating in Class A/B linear

mode over a frequency range of 2305 MHz to 2360 MHz and is fully protected against

input overdrive, temperature, and output load VSWR conditions. The protection cir-

cuitry is self-correcting and allows restoration of the HPA to normal operation upon

removal of the fault.

The HPA is a separate sub-assembly Least Replaceable Unit (LRU) installed on slid-

ing rails in the repeater enclosure. It contains an integrated AC/DC power supply, a

pre--driver, a driver, a 5-way splitter, ﬁve individual power ampliﬁer modules, a 5-

way combiner, and an HPA controller.

2.4.1

HPA CONTROLLER

The HPA Controller monitors various parameters and reports current values and

summary alarms to the repeater main controller via the RS485 interface. The vari-

ous monitored parameters and statuses are the power modules working conditions

(DC voltages and currents), the temperature inside the HPA assembly, the HPA for-

ward and reﬂected power levels, input power and gain, RF power inhibit, HPA power

supply enabled/disabled, input/output overdrive alarm, over-temp alarm (announced

prior to shut-down), over-temp fault, HPA shut-down alarm, output device failure

alarm, driver device failure alarm, HPA low gain alarm, power supply AC fault, and

power supply DC fault.

The HPA Controller also performs HPA pre-driver control, provides the HPA power-

up and shut-down procedure, and interfaces the HPA to the host (SPU Main Control-

ler). If the HPA controller detects a problem with a speciﬁc PA module, it shuts down

the entire HPA. The SPU main controller can restart the HPA utilizing the remain-

ing operational PAs. If the number of faulty PAs exceeds a predetermined threshold,

the HPA can not be restarted by the host.

Since the HPA is a constant gain block, it is individually calibrated to maintain RF

performance under varying operating conditions. Calibration is performed on the

forward, reﬂected, and input power sensors. A calibration table dependent on tem-

perature and frequency is stored in the internal EEPROM of the HPA controller.

The HPA controller reports alarms to the main controller and maintains a log of

alarms. Alarm entries contain the alarm ID and monitored parameters prior to

alarm activation. The alarm log is stored in an internal EEPROM. The HPA control-

ler can enable/disable the output RF and also turn the integrated power supply DC

power ON and OFF.

2.4.2

HPA POWER SUPPLY

The HPA Power Supply is a high performance power source that delivers appropri-

ate voltages and current necessary to operate the HPA at its required performance

level. The power supply resides in a separate compartment inside the HPA module

and employs four independent AC-to-DC converters operating in parallel. The con-

verters’ outputs are combined on a single bus and connect to the input terminal of

the Power Distribution/Controller board located in the power supply compartment.

The Power Supply contains supervisory circuitry to report the status of the AC input

voltage and DC/DC converters operation status to the Power Distribution/Controller

module. This Controller module also monitors the Power Supply DC output voltage

and the current draw of each of the HPA sub-modules, and reports these parameters

back to the Main System Controller via the serial port. In addition, the Power Sup-

ply has the ability to enable/disable the power to the HPA when so commanded by

the Main System Controller.

2.4.3

HPA PREAMPLIFIER (PREDRIVER)

The pre-driver is the ﬁrst amplifying stage of the HPA. It employs three stages of

ampliﬁcation-a Monolithic Microwave Integrated Circuit (MMIC) ampliﬁer and two

LDMOS transistors. The pre-driver raises the output power of the RF from the up-

converter by 38 dB and feeds the ampliﬁed RF into the HPA driver ampliﬁer. The RF

signal from the pre-driver input is also coupled to the RF detector circuit which pro-

vides detected RF to the HPA controller for monitoring and gain control. The coupled

RF signal is routed through a PIN diode attenuator to maintain the HPA gain con-

trol loop. The pre-driver ampliﬁer, via a Gallium Arsenide (GaAs) MMIC RF switch,

can turn the RF signal on or off by way of a logic level HIGH RF Shutdown TTL con-

trol signal.

2.4.4

HPA DRIVER AMPLIFIER

The driver ampliﬁer, employing two parallel ampliﬁers, receives the RF output from

the pre-driver and ampliﬁes it by 13.3 dB. The output of the driver ampliﬁer is fed

into a ﬁve-way splitter at a power level of 43 dBm.

2.4.5

HPA POWER SPLITTER

The ﬁve-way power splitter is connects directly to the HPA driver ampliﬁer RF out-

put. The splitter evenly distributes this RF power to the ﬁve individual output power

ampliﬁer modules.

2.4.6

POWER AMPLIFIER MODULES

The ﬁve power ampliﬁer modules are identical to the driver ampliﬁer module. These

modules are paralleled and receive equal inputs from the ﬁve-way power splitter.

The ampliﬁers each contribute a gain of 13.3 dB to their respective input, the ﬁve-

way combiner/coupler.

2.4.7

COMBINER/COUPLER

The ﬁve RF power ampliﬁer outputs are combined into one via a zero-degree star

combiner. Two stripline couplers provide output signal sampling. One coupler’s out-

puts are terminated with SMA connectors and are used to provide external forward

and reﬂected RF monitoring ports. The other coupler’s outputs are detected using

true-type RF detectors installed on a coupler printed circuit board. These detected

signals are fed to the HPA Controller for control and monitoring purposes. The

detected signals and DC power for the on-board detectors are routed through 6-pin

Molex connectors installed on a coupler board. The 5-way combiner/coupler requires

external +5VDC ± 0.5 volts. When the combiner/coupler is installed on the HPA chas-

sis, the inputs are connected directly to the power modules’ output pins. The output

of the combiner is connected to the central conductor of the HPA output connector.

2.5

S-BAND OUTPUT FILTER

The output ﬁlter is a bandpass ﬁlter and provides attenuation of the out-of-band

emissions generated by the HPA. The attenuation is to comply with the require-

ments of TN-SPEC-2.1.0, Terrestrial Network Technical Speciﬁcation, Transmitter

RF Emissions.

2.6

OUTPUT COUPLER

The output coupler, connected to the output port of the transmit ﬁlter, is the ﬁnal

component in the transmitter chain. The coupler samples the composite RF power

level at the repeater RF output. The RF levels at the FWD and REF ports are mea-

sured with the RF detectors and reported to the repeater main controller via the

RS485 interface. The output coupler provides test ports for connection to external

test equipment.

2.7

POWER DISTRIBUTION

See

Figure 2 - 12

and

Figure 2 - 13

for a simpliﬁed block diagram and an isometric view

of the Power Distribution Unit (PDU). The PDU is mounted on the bottom of the

repeater cabinet (see

Figure 1 - 5

), receives the input commercial 208VAC power, and

distributes required power to the repeater modules.

The PDU is comprised of seven circuit breakers, two surge protectors, two RFI power

line ﬁlters, two latching relays, forty two-stage feed through terminal blocks, and one

double grounding terminal. The front panel of the PDU houses the seven circuit

breakers and one power outlet.

The circuit breakers are as follows:

MAIN POWER – one 32A, 250VAC, 3-pole circuit breaker controls the incoming

208VAC to the repeater from the commercial source. Throwing this breaker will

remove all power from the repeater.

FANS – one 5A, 250VAC, 2-pole breaker powers the axial fans.

HPA – one 25A, 250VAC, 2-pole breaker supplies the HPA power supply. SPU – one

5A, 250VAC, 2-pole breaker supplies the SPU power supply

EXT HEATER – one 5A, 250VAC, 2-pole breaker powers the external heater

INT HEATER – one 5A, 250VAC, 2-pole breaker powers the internal heater

AUX POWER – one 10A, 250VAC, 2-pole breaker supplies 120VAC, 5A, to the AUX

POST-INSTALLATION INSPECTION/TEST

Post installation inspecting/testing is described below as phase one, two, and three

inspecting and/or testing. Phase one and two inspecting/testing is to satisfy the site

owner that the system conforms to the owner’s requirements. Phase three testing is

the Alcatel-Lucent SIRIUS ﬁeld test performed after installation or major equipment

maintenance to ensure that the repeater is performing according to SIRIUS require-

ments. An inspection/test form template is provided at the end of this section. A ﬁeld

test report form template is provided at the end of the Turn-up and Testing section of

this manual.

3.10.1

Inspection/Test Phases

Post installation inspection/testing will normally consist of three phases involving

the site owner’s representative, Alcatel-Lucent’s representative, and SIRIUS

Radio’s representative. A written record of each phase will be made identifying the

speciﬁc inspections and/or test(s) accomplished and the satisfactory or unsatisfac-

tory result(s) of each. A copy of the results will be furnished to each participating

representative.

3.10.1.1

Phase One Inspection/Testing

Phase one inspection/testing will be performed at the discretion of the site owner’s

representative. The purpose is to ensure that Alcatel-Lucent installed equipment

meets all requirements established by the site owner. The site owner’s representa-

tive

(s) in conjunction with the Alcatel-Lucent representative and the SIRIUS Radio

representative will be involved in the inspection/testing process. Deﬁciencies will be

identiﬁed, recorded, and presented to the Alcatel-Lucent representative for correction.

3.10.1.2

Phase Two Inspection/Testing

Phase two will only be required if there were discrepancies found during the phase

one inspection/testing. After correction of the discrepancies, the site owner’s repre-

sentative, Alcatel-Lucent’s representative, and SIRIUS Radio’s representative will

once again be involved in an inspection/test to ensure satisfactory correction. Results

of the phase two inspection/testing will be recorded and signed by all representatives

and a copy distributed to each.

3.10.1.3

Phase Three Testing

Phase three testing consists of The Alcatel-Lucent representative in conjunction with

a SIRIUS Radio representative performing repeater system ﬁeld testing to ensure

satisfactory system operation. Final test results will be recorded and signed by each

representative who in turn will receive a signed copy.

5OPERATION

5.1

GENERAL

This section addresses control, communication, and parameter modiﬁcations of the

DTR-0200-SA-SIRIUS terrestrial repeater. It also provides descriptions of controls,

indicators, test points, and connectors for the repeater.

Refer to Paragraph 5.7 for repeater operating procedures.

Refer to Paragraph 5.8 for controls and indicators.

5.2

CONTROL AND COMMUNICATION

The DTR-0200-SA-SIRIUS terrestrial repeater can operate in either of two condi-

tions; remote control condition or local control condition

5.2.1

Remote Control Condition

In the remote control condition the Network Management Center (NMC) operator can

control and monitor the repeater from his/her position via telephone line dial-up, and

by use of WEB and SNMP interfaces to perform network management.

5.2.2

Local Control Condition

In the local control condition the technician can control and monitor the repeater from

the terrestrial site location. The technician uses a laptop PC for local control and

maintenance procedures. The PC communicates with the repeater via Ethernet and

Graphical User Interface (using Internet Explorer) or Command Line Interface (CLI)

protocol using the RS-232 Comm Port.

5.2.3

Control and Communication Interfaces

There are three interface ports provided for control and communication. They are:

• RS-232 Serial Port (DB9) –used for local control, status information, initial setup,

and troubleshooting. Access is local via laptop PC and the supported protocol is

Command Line Interface (CLI).

• V90 Modem Port (RJ11) – used for remote control and status information. Access

is from the NMC via dial-up modem and telephone and the supported protocols

are SNMP

, WEB Interface, and Telnet.

• Ethernet Port (RJ45) – used for local control and LAN access. Access is local and

the supported protocols are SNMP, WEB Interface, and Telnet.

5.2.4

Remote/Local Control Switching

The normal condition for repeater operation is the remote control condition. For a tech-

nician to perform testing and maintenance from the local terrestrial site, the repeater

must be switched to the local control condition. Switching is activated by the use of an

SPU front panel push-button switch. LEDs on either side of the switch identify the

repeater control condition as being in local or remote. Placing the repeater in the local

OPERATION 3EM21522AAAA

DTR-0200-SA-SIRIUS Issue 1, March 2008

5-2

mode prevents a remote operator from accidentally turning on the HPA from the

remote site and applying high RF level from the repeater. This could seriously injure

the technician working on the repeater at the local site and/or damage the repeater.

5.3

MODES OF OPERATION

There are two main parameter groups which determine the operating mode. They are

the Repeater Operating Mode parameter group and the Modulator Operating Mode

parameter group.

5.3.1

Repeater Operating Modes

The three repeater operating modes are Broadcast, Standby, and Manual. The

repeater’s normal operating mode is Broadcast. Under normal, no-fault, conditions if

the repeater has an AC power shut-down, upon return of power its AC power-up algo-

rithm will restore operation to the same mode of operation prior to the loss of power.

5.3.1.1

Broadcast Mode

This mode allows the repeater to transmit real signals or test signals, run all the pro-

tection loops and ALC. This is the normal operating mode for the repeater. It receives

its input signal from the satellite, or generates a test signal, and transmits an orthog-

onal frequency division multiplexing (OFDM) signal for terrestrial broadcast. In this

mode, the Main Controller automatically maintains all repeater functions. To operate

in the Broadcast mode, the following conditions must be met:

• The repeater must be receiving an input signal and be locked to the input

stream (if the modulator is in the test mode, the VSAT satellite signal

presence is ignored).

• The ALC loop must be running.

• There must be good GPS signal quality (if the modulator is in the test

mode, the GPS signal presence is ignored).

• There must be no modulator alarms.

• There must be no VSAT alarms (if the modulator is in the test mode, the

VSAT satellite signal presence is ignored).

• There must be no GPS alarms (if the modulator is in the test mode, the

GPS signal presence is ignored).

• There must be no Up-converter alarms.

• There must be no Reﬂected Power alarms.

5.3.1.2

Standby Mode

In this mode the repeater is off the air and afﬁrms that the HPA is off while all other

components are operating normally. The up-converter output is muted, ALC is off, and

the HPA is switched off by disabling the HPA power supply.

3EM21522AAAA OPERATION

Issue 1, March 2008 DTR-0200-SA-SIRIUS

5-3

The operating conditions in the Standby mode are:

• AC power is applied to the SPU, HPA, and fans.

• The HPA power supply is disabled.

• The HPA RF switch is OFF.

• The Up-converter output is muted.

• The cabinet fans are turned on.

5.3.1.3

Manual Mode

This mode allows manual control of the repeater for the technician to perform mainte-

nance and/or testing or troubleshooting. In the Manual Mode most commands can

only be accessed through the “administrator” login. The operator must log in as a sys-

tem administrator using the default password “ipradmin”. The operator now has

authority to alter parameters.

The manual mode must be used with caution. If parameters

are changed indiscriminately, unintentional damage to the

repeater and loss of factory settings could occur.

When the repeater is switched to the Manual Mode, it maintains all its system set-

tings which were in effect prior to the switchover. The RF output DAC last value will

remain until changed by the operator. The range of DAC values is limited to those

within the minimum and maximum permitted values required to maintain the up-

converter output power.

5.3.2

Modulator Operating Modes

• The modulator has seven operating modes:

• Standby Mode

• Run Mode

• CW Mode

• Two Tones Mode

• Notch Mode

• Comb Mode

• PRBS Mode

Of these seven operating modes, the technician will only use Standby Mode and Run

Mode. All other modes are for factory use only.

GRAPHICAL USER INTERFACE (GUI)

The GUI WEB interface uses a PC for maintenance and support of the repeater,

and for fault and status reporting. The interface uses a simple hierarchical menu

structure which is user friendly and provides access to parameters. The parameters

are classiﬁed in ﬁve categories; Status, Conﬁguration, Alarms, NMS User, and System

Parameter. Figure 5 - 1 shows the GUI Main Menu which, in addition to providing cur-

rent repeater operating information, provides access to set up or change parameters as

required. The parameter categories and their pull down submenus are accessed from

the

GUI Main Menu. These submenu screens are self-explanatory and subdivide the

repeater’s status and parameters according to their functionalities. See

The web server is a single threaded server, and as such, allows only one

connection at a time. This means an upgrade via phone line can take 10

minutes or more for ﬁle transfer. This is dependent upon speed and ﬁle

size. During transfer, the pop-up dialog box remains blank and only

starts showing information after the ﬁle is completely transferred.

COMMAND LINE INTERFACE (CLI)

The CLI can be accessed via the serial RS-232 port located on the SPU front panel.

(COMM PORT setting= 9600-8-n-1) or the telnet (port 26).

To use CLI, after system boot, establish connection to the RS-232 or TELNET interface.

Press “Enter” to obtain the Login prompt. See Figure 5 - 39.

REPEATER OPERATING PROCEDURES

5.7.1

Local/Remote Operation

The repeater can be controlled and monitored either locally on site or remotely from a

network management center (NMC). The SPU front panel LOCAL REMOTE switch

controls the operating mode of the repeater.

All locally performed actions require the repeater to be in

the LOCAL operating condition. Prior to switching the

repeater to LOCAL, the on-site technician will coordinate

with the NMC operator. This will prevent conﬂicting actions

between the NMC and on-site operators and preclude possi-

ble personnel injury and/or equipment damage.

OPERATION 3EM21522AAAA

DTR-0200-SA-SIRIUS Issue 1, March 2008

5-34

5.7.1.1

Local Operation

For repeater local control (during initial setup and/or maintenance sessions, etc.) and

status information, a PC can be connected to the LAN and established via the Ether-

net (RJ45) port which provides access to the Web and GUI interface. This is the pre-

ferred method.

An alternate access method is via the RS-232 (DB9) serial port using the Command

Line Interface (CLI) protocol. The RS-232 provides access to CLI and allows the oper-

ator to perform initial setup and/or troubleshooting when network connectivity may

not be available or desired.

5.7.1.2

Setting to Local Operating Condition

1. Coordinate with the NMC operator.

2. Press the SPU front panel LOCAL/REMOTE switch to change to the

LOCAL position (see Figure 5 - 41).

3. Wait for the LOCAL LED to switch from Red to Green (approximately 2.5

minutes).

5.7.1.4

Steps to Access the Repeater in Local Operating Condition via RS-232

1. Connect PC to RS-232 Console Port (SPU front panel) using a straight

cable.

2. Access the repeater via the HyperTerminal and using CLI commands.

The Modulator can also be directly accessed using an RS-232 Null

Modem cable connected to the Modulator RS-232 LOCAL PORT connec-

tor on the modulator back panel, and using CLI commands.

5.7.1.5

Remote Operation

Remote repeater access and communication is via V90 modem (RJ11) and a dial up

telephone line connected to the Network Management Center (NMC).

When an alarm occurs, the repeater’s main controller attempts to establish communi-

cation with the NMC through the dial up modem. If the phone line is busy, the con-

troller will retry after a pre-determined time period. Once the main controller ﬁnishes

sending all the traps to the NMC, the controller switches to a slave mode. In the slave

mode, the controller waits for a connection to be established with the NMC using pre-

conﬁgured SNMPv3 parameters. This allows NMC to poll its parameters/status or

make changes to various system parameters.

5.7.2

Operating Modes

Operating mode conﬁguration can occur in either of two main parameter groups;

Repeater Operating Mode parameters or Modulator Operating Mode parameters.

5.7.2.1

Repeater Operating Modes

In general, under no fault conditions, the repeater AC power up algorithm will restore

repeater operation to the existing mode condition prior to AC shutdown (if the

repeater was in Standby prior to AC shut down, upon reapplication of AC the repeater

would return to Standby). There are three repeater operating modes:

1). Standby mode

2). Broadcast mode

3). Manual mode

Mode selection is via the GUI Main Menu. From the Main Menu select Conﬁg =>

Repeater Operating Mode => Standby

, Broadcast, or Manual. See Figure 5 - 44.

Figure 5 - 44 Repeater Operating Mode Screen

5.7.2.1.1

Standby Mode

The Standby Mode is used to take the repeater off the air without removing all power.

The up-converter output is muted, ALC is off, and the HPA is switched off by dis-

abling the HPA power supply.

Following are the repeater operating conditions when in the Standby Mode:

• AC power is applied to the SPU, HPA, and fans

• HPA power supply is disabled

• HPA RF switch is off

• Up-converter output is muted

• Cabinet fans are turned on

5.7.2.1.2

Broadcast Mode

The Broadcast Mode is the normal operating mode for the repeater and allows the

repeater to transmit either real (satellite input) or internally generated test signals,

transmit OFDM signals for terrestrial broadcast, and run all the protection loops/

ALC. In this mode, all repeater functions are automatically maintained by the Main

Controller.

Manual Mode

The Manual Mode is for testing and troubleshooting. Refer to the Maintenance sec-

tion of this manual for use of the Manual Mode. When switched to the Manual mode,

the repeater maintains all the system settings that were in effect in the previous

mode.
