Refer to the tables in Section 1 for the technical characteris-tics and the major components.2.2.1SIGNAL FLOWThe 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

3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-52.3MAIN FUNCTIONSThe 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.2.3.1SIGNAL PROCESSING UNIT (SPU) SUB-ASSEMBLYFigure 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).

3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-92.3.1.1L-Band (VSAT) ReceiverThe 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 Panel2.3.1.2Modulator 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.

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.Figure 2 - 6 Up-Converter Module Panel2.3.1.4SPU Main Controller BoardSee 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).
3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-11Control 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 WANForward 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.
Functional Description 3EM21522AAAADTR-0200-SA-SIRIUS Issue 1, March 20082-12Back-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 repeaterHeartbeat – 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 UPSFigure 2 - 7 Controller Board Panel

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.2.3.1.4.2Supervisor 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 Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-15•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). 2.3.1.4.3GPS 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 J130.2.3.1.4.4Dial-up ModemTwo 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.2.3.1.4.5Ethernet 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.2.3.1.4.6Uninterruptible 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.
Functional Description 3EM21522AAAADTR-0200-SA-SIRIUS Issue 1, March 20082-16A 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)2.3.1.4.7SPU Power SupplyThe 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@1AThe power supply input is 208VAC/50-60 Hz.2.3.1.4.8SPU Compartment HeaterThe SPU compartment heater protects the SPU enclosure from freezing and/or con-densation.
3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-172.4HIGH 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.Figure 2 - 10 HPA Panels

3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-192.4.1HPA 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.2.4.2HPA POWER SUPPLYThe 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.
Functional Description 3EM21522AAAADTR-0200-SA-SIRIUS Issue 1, March 20082-202.4.3 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.2.4.4HPA 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.2.4.5HPA POWER SPLITTERThe 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. 2.4.6POWER AMPLIFIER MODULESThe 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.2.4.7COMBINER/COUPLERThe 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.
3EM21522AAAA Functional DescriptionIssue 1, March 2008 DTR-0200-SA-SIRIUS2-212.5S-BAND OUTPUT FILTERThe 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.2.6OUTPUT COUPLERThe 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.2.7POWER DISTRIBUTIONSee 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.

3EM21522AAAA OPERATIONIssue 1, March 2008 DTR-0200-SA-SIRIUS5-15OPERATION5.1GENERALThis 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.5.2CONTROL AND COMMUNICATIONThe DTR-0200-SA-SIRIUS terrestrial repeater can operate in either of two condi-tions; remote control condition or local control condition5.2.1Remote Control ConditionIn 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.5.2.2Local Control ConditionIn 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. 5.2.3Control and Communication InterfacesThere 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.5.2.4Remote/Local Control SwitchingThe 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 3EM21522AAAADTR-0200-SA-SIRIUS Issue 1, March 20085-2mode 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. 5.3MODES OF OPERATIONThere 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.5.3.1Repeater Operating ModesThe 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.5.3.1.1Broadcast ModeThis 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.5.3.1.2Standby ModeIn 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 OPERATIONIssue 1, March 2008 DTR-0200-SA-SIRIUS5-3The 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.5.3.1.3Manual ModeThis 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.5.3.2Modulator Operating Modes• The modulator has seven operating modes:• Standby Mode• Run Mode• CW Mode• Two Tones Mode• Notch Mode• Comb Mode• PRBS ModeOf these seven operating modes, the technician will only use Standby Mode and Run Mode. All other modes are for factory use only.WARNINGPossibility ofDamageto Equipment
OPERATION 3EM21522AAAADTR-0200-SA-SIRIUS Issue 1, March 20085-45.4GRAPHICAL 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 Figure 5 - 2.Figure 5 - 1 GUI Main Menu

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.

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.5.7.1.5Remote 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.5.7.2Operating ModesOperating mode configuration can occur in either of two main parameter groups; Repeater Operating Mode parameters or Modulator Operating Mode parameters. 5.7.2.1Repeater Operating ModesIn 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 mode2). Broadcast mode3). Manual modeMode selection is via the GUI Main Menu. From the Main Menu select Config => Repeater Operating Mode => Standby, Broadcast, or Manual. See Figure 5 - 44.
