04/10/2007 1. SAFETY INSTRUCTIONS 1.1. INTRODUCTION In spite of the electric well cared used for the equipment design, the installation and maintenance personnel may be exposed to a certain inherent hazards in the electronic equipment treatment. Since Mier Comunicaciones bets for the security of its customers, in the current chapter is pretended to offer a guide of the possible existing dangers, and a group of recommendations to avoid their development as well. For these reasons, is extremely important to read carefully this chapter before starting any operation over the unit (chapter 1). However, someone always can get in contact with our Technical Attention Service (TAS) to solve any kind of doubt. NOTE: the purpose of this section is not to contain a complete description of all the precautions that the operators must be bear in mind using electronic equipment. Mier Comunicaciones doesnt take responsibility for injuries suffered due to inappropriate and irresponsible procedures or to dispose of personnel without the experience and/or required qualification. 1.2. GENERAL RECOMMENDATIONS In the next lines will be detailed some general recommendations to stick on to follow a correct security plan at the time to carry out the installation, the maintenance or any type of adjustment. All electrical installation and its respective maintenance must be carried out by suitable qualified personnel. Do not do any work in the unit unless there is another person who is able to provide first aid services. Do not touch overheated components without suitable precautions to avoid burns. If it is required to raise and to transport the unit, it must be done by more than one person. The unit weight is too high (25-30Kg depending on the unit) and it could cause injuries. The fuses, switches and other protection devices have the finality to guarantee security under overloads and short circuits. Pay high attention to them. When a security device replacement is performed, original device with the same electric specifications has to be used. When a replacement with these characteristics is done, do a security check to ensure its correct operation. In order to do any sort of work without operating requirement, ensure that the unit is unconnected to the supply power. In this case, not to assume SAFETY INSTRUCTIONS 7/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 either that electric hazard doesnt exist (even in the parts that apparently show electric isolation). The capacitors might retain dangerous electric potentials for a certain period of time after switching off the unit. Wait for 5 minutes to ensure that the capacitors have been discharged. Not to discharged them by short circuits. Disconnect the antenna as well. Other active equipments connected to the same antenna can cause a harmful energetic feed back through the connection cable. When it is not possible to disconnect the antenna must be carried out other possible precautions to establish a voltage absence. Fire risk ESD hazard Burns hazard Electric shock hazard RF hazard 8/87 Fire risk Figure 1.- Identification of the unit hazards. SAFETY INSTRUCTIONS FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 1.3. ELECTRIC SHOCK HAZARD The equipments (transmitters, transposers or gap fillers) transport a big amount of energy and hence they are a hazard supply. An electric shock happens when somebody gets in contact with an electric energy supply which causes energy propagation through his body. It may cause a shock, whose consequences might vary. It could result in nothing or by contrast it could be even lethal. For this reason, pay attention to the following recommendations:

The current intensity is the most important magnitude to predict the kind of damage suffered. The harmful current threshold is from 80mA at a frequency of 50 Hz. Known the relation between the intensity and the voltage, it is considered a dangerous electric potential from 24V AC or 50V DC, which can cause serious bad consequences. Remember that low voltage supplies with high intensity may be as dangerous as high voltage supplies. Do not use connections in inappropriate conditions. If it is appreciated any deteriorated connection, replace it immediately. Otherwise, it could cause either a fire or an electric shock. Do not remove either the external covers or the internal lids of the equipment while it is operating, unless it is absolutely necessary to do some work. One of the main functions of them is to avoid contact with high voltages. Do not touch the connections with wet hands. The essential resistive element of the human body is constituted by skin, which varies according to the person. The resistance among two parts of the body is within some KW

, even though it is reduced when it is wet. In front of any measurement, keep one hand in the pocket to avoid the worst path current is from hand to hand since the electric flow would pass through the chest cavity. Electric shocks apart from producing the shock may cause burns in the part of the body which has been in contact with the electric conductor. 1.4. ELECTROSTATIC DISCHARGE HAZARD Electrostatic discharges (ESD) are an electric event that produces an electrostatic field discharge when bodies with different electric potential get in contact. They are extremely dangerous for electronic devices and therefore it is important to bear them in mind. Please, follow the next recommendations:

Ensure the discharge of the static electricity of the operators and electronic devices that have been able to accumulate before touching any device or connecting devices. SAFETY INSTRUCTIONS 9/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 Ensure that the ESD precautions are fulfilled before extracting PCBs. Always hold up the boards with the edges. Do not touch ever the board either through the print circuit or the connection pins. Handle ESD sensitive devices in a free static electricity area. If it is possible, use anti-static carpets in both floor and workstation. In order to transport ESD sensitive device, put it in an anti-static bag. If it is required to touch electronic devices of the equipment during its either installation or maintenance, the operators must be equipped with ESD protection. For instance, they can use an anti-static wrist. Avoid contact between boards and clothes. If an anti-static wrist is used, take care: it only protects the board versus body static electricity. Thus, clothes might damage boards. 1.5. RF HAZARDS Since RF lines may also cause certain damages, in the following lines it is described several recommendations to prevent hazards related with equipments that include this kind of lines. Ensure neither switch on the unit with RF lines in open circuit nor disconnect these lines when the unit is operating. Although the unit possess protection versus these events (signal is deactivated automatically), it could result in serious damages to the personnel. When an event as just explained happens, electric arcs may be generated, producing ultraviolet radiation. If these arcs have enough intensity, they may cause burns and temporal ocular injuries. When an instrument (wattmeter, spectral analyzer,) has to be connected to a high frequency output, use suitable attenuators or dummies to avoid damages to the unit final amplifiers and to the measurement instrument. Do not remove either the external covers or the internal lids of the equipment while it is operating, unless it is absolutely necessary to do some work. One of their main functions is to avoid external dangerous radiation produced by the unit. 1.6. FIRE RISK Even though it is not much common, there is a risk fire in presence of electronic equipment with these features. Moreover, flames and heat applied to the unit produce extremely dangerous gases generated by the devices materials. For this, pay attention to the next good practices:

Ensure that the operators have basic formation of fire-fighting. Apply the most appropriate methods with specialised anti-fire material. SAFETY INSTRUCTIONS 10/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 Ensure the absence or the shortage of flammable materials in the room where the unit is located. Ensure that all the doors of the room are closed to prevent a possible expansion in case of fire. Do not remove either the external covers or the internal lids of the equipment while it is operating, unless it is absolutely necessary to do some work. One of their main functions is to avoid physical contact that could produce a short circuit. Then a fire could origin. When a fuse replacement is performed, original fuse with the same electric specifications has to be used. Otherwise, an excessive current though a fuse could cause a fire if it is not prepare for this intensity of current. The features of the fuses are shown in Table 1.

04/10/2007 2. INSTALLATION AND PUTTING INTO OPERATION In the current chapter it is described the procedure that has to be taken place for a suitable both installation and start-up operation of the unit. Before doing any work in the equipment installation, please read safety instructions (chapter 0). Note the whole electric installation and its respective maintenance have to be done by appropriated qualified personnel. In each connection of this section appears the type (N, BNC,) and the identification

(Jx) of its connector. All these connectors can be seen in mechanical description chapter. In order to understand all the explanations of this section and to avoid any mistake it is recommended to look both chapters at the same time. Furthermore, the specifications shown in this chapter are also in technical specifications in a wider way. 2.1. ENVIRONMENTAL SPECIFICATIONS The installation can be made in a 19 rack or over a table, using the correct accessories for each case. The rack must be perfectly ready to support the weight of all the electronic equipment that is installed in it. For security reasons, the maximum height of the rack has to be of 42U. Moreover, the unit installation must be done in a safe place avoiding weather inclemency as follows:

Operating temperature margin:

Its installation must allow the entry of the necessary air through the front panel and the exit of it through the back panel with no obstructions. No obstacle should block the air entry and exit. Basic unit configuration does not include input air filter. The unit must be installed in a dust-free ambient. 2.2. RACK MOUNTING When the equipment must be installed in a multi-unit rack assembly, the following precautions must be taken:

Elevated Operating Ambient If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the manufacturer. INSTALLATION AND PUTTING INTO OPERATION 13/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 Reduced Air Flow Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Mechanical Loading Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading. Circuit Overloading Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. Reliable Earthing Reliable earthing of rackmounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips). 2.3. UNIT CONNECTORS Before connecting any cable make sure that the power supply is disconnected. It will be the last cable to connect. This will prevent any body injury caused by an electric shock and any possible damage to the unit. As the plug is considered to be the disconnect device for the equipment, the socket-

If this LED doesnt light see troubleshooting (chapter 10). 13. Check that the red alarm LED doesnt light yet. If the LED lights see troubleshooting (chapter 10). 14. Check that the unit is operating correctly: ensure that the measurements of the equipment satisfy the specifications of the protocol provided by Mier Comunicaciones. The explanation of taking these measurements is detailed in control software description (chapter 7). If any wrong measurement appears see troubleshooting (chapter 10). Once the unit is switched on correctly, if it is required either to know any type of information related to the unit or to change any parameter, consult control software description (chapter 7). 2.5. MAINTENANCE RECOMMENDATIONS With the purpose of ensuring a properly operation of the equipment the following maintenance rules have to be accomplished:

At regular periods of time is convenient to check the equipment work conditions and the correct performance of the security devices. The mentioned check has not to be done if the security devices have been working under INSTALLATION AND PUTTING INTO OPERATION 21/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

At regular periods of time should be carried out a revision, comparing the measurements given by the control board and by the protocol. If the result obtained is bad, see troubleshooting (chapter 10). In non-clean environments unit cleaning is absolutely necessary in order to avoid failures. If the installation incorporates air filters, they have to be replaced when its service time expires. Otherwise, the air flow in the unit will not be appropriate. The unit includes fan units. Service time of them is 70,000h: they have to be replaced when this time is expired. In case the unit needs a replacement:

The equipment is composed by several independent circuits. Revise its state before starting any work. Disconnect the neighbourhood circuits to prevent a possible accidental contact. When MOS devices replacement are performed, follow the standard rules to avoid injuries due to static charges and solders. When PCBs (Printed Circuit Board) components replacement are performed, pay attention in not to damage their traces due to a deficient protection of the board, involuntary scratches or a bad manipulation by the operator. Remember that FET

(Metal-Oxide Semiconductor) devices can look like defective due to possible leakages in the PCB. Clean the PCB and repeat the check process before assuming that it is defected.

INTRODUCTION designed repeaters and manufactured to know or estimate Intelligent High Gain On-Channel Repeaters (hereinafter HGOCR-I) are the new solution for SFN by MIER COMUNICACIONES. Traditional on-channel repeaters require fundamental parameters such as reception level and isolation between antennas before their installation. The advantage of HGOCR-I is that it incorporates a global gain control that allows to install the equipment without requiring this information, therefore it offers a maximum flexibility for network planning, minimizes its incertitude and simplifies the equipment installation and commissioning. When the HGOCR-I starts up, it automatically adapts to the environment changing conditions, therefore there is no longer need to do previous in-field measurements, allowing a faster and easier deployment. The new global gain control compensates slow environment variations, whereas the new generation echo canceller takes care of fast variations, both together guarantee HGOCR-I in long term stability. HGOCR-I offers a high immunity to medium/long term variations. As the new global gain control avoids the risk of oscillation, the output power hardly ever needs to be shut down.

04/10/2007 3.2. OCR, HGOCR & HGOCR-I Traditionally, before installing a conventional On-Channel Repeater (OCR) or a High Gain On-Channel Repeater (HGOCR) in a site, it is required to estimate two fundamental parameters:

Estimated reception level (Pin), and Available isolation between transmission and reception antennas (I). Once this parameters are known, system stability can be warranted by limiting the OCR / HGOCR output power as shown in the following equations:

P out

dBm

) P out

) dBI

) 10 dB P in

, for OCR for HGOCR Having to know these two parameters before installing the On-Channel Repeater implies a difficulty in network planning based On-Channel Repeaters. Whereas the reception level is easy to estimate using specific software for network planning, the isolation between antennas is much harder to estimate, because it depends on several factors, such like physical placement of the two antennas, distance and relative angle between antennas, site environment, weather conditions, etc. As a result, some uncertainty may arise. A possible solution is to measure on-site this two parameters once the antennas have been installed, but this is an expensive and low efficient approach. Moreover, it requires very specific instruments to measure the isolation between antennas. Intelligent HGOCR (hereinafter HGOCR-I) allows to overcome this obstacle, offering the following advantages:

It provides maximum flexibility during network planning phase, It simplifies equipment turning-gon, It makes the HGOCR-I independent from changing reception level and/or isolation conditions, guarantying its long term stability. This is achieved combining the new generation active echo canceller system and a smart control system that adapts overall gain to reception level and isolation between antennas conditions.

04/10/2007 3.3. HGOCR-I PHILOSOPHY HGOCR-I is continuously performing a real-time monitoring of the operating gain margin (GM). Therefore HGOCR-I can increase or reduce its gain at any time that the echo power level exceeds the previously defined thresholds (these thresholds are user-programmable settings). So, HGOCR-I provides a global gain control system, depending on the existing echo power level. This global gain control system (that depends on the echo power level) is slow enough to let the fast Gain Margin variations be absorbed by the active echo canceller system, whereas the long-term slow variations, are compensated by the HGOCR-I itself. When the HGOCR-I is started up, an initial minimum gain condition is loaded, so minimum output power level is obtained. The available output power level is gradually increased until it reaches on of the two following conditions:

1) Gain Margin limit specified by the user has been reached, or:

2) Maximum output power level specified by the user has been reached

(usually equal to HGOCR-I nominal power) The HGOCR-I avoids the need to do previous isolation measurement, simplifying the installation and turning-on process. User configurable parameters, regarding the gain control system, are:

P max: Maximum output power level (usually equal to nominal power) P min: Minimum output power level GM min: Minimum admissible Gain (Maximum admissible echo power level) Hysth-DN: lower hystheresis threshold Hysth-UP: upper hystheresis threshold Intelligent gain control will start working as soon as the gain margin exceeds any of the specified limits:

If (GM < GMmin HysthDN) and (Pout > Pmin) If (GM > GMmin + HysthUP) and (Pout < Pmax) Gain will be decreased Gain will be increased INTELLIGENT HIGH GAIN ON-CHANNEL REPEATER (HGOCR-I) 25/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 HGOCR-I advantages vs. HGOCR:

It eases network planning and minimize its incertitude It simplifies the On-channel repeater start up It improves immunity towards the medium-term and long-term variations of Gain Margin conditions (i.e. reception level or isolation between antennas variations)  Minimizes service shutdowns, then improving system availability.

04/10/2007 3.4. OPERATING EXAMPLES Figure 1 shows a simulation of a 50W (47dBm) HGOCR behaviour when reception level and/or isolation between antennas conditions are changing along time. As shown in the Gain Margin figure, the limit GM=-10dB (echo power level 10dB higher that received signal power level) is highlighted, since when GM exceeds this value the system stability is not guaranteed and shutdowns of the transmitted signal may occur. It can be seen that under these conditions, service is interrupted approximately a 10% of the time.

As a result, the continuity of service is guaranteed for a 100% of the time. The following figures show the same simulation for a HGOCR (Figure 3) and a HGOCR-I (Figure 4), but in this case the isolation presents instantaneous variations added to long term variations.

(to be performed by skilled personnel) can be made by removing the upper lids. The equipment is divided in four external parts:

1. Front panel, 19 4U. Air inlet must be left free. This front panel also includes four safety screws which allow the attachment of the equipment to the cabinet if necessary. 2. Back panel. Air cooling exits must be left free. 3. Sides. Allow the fixation of the equipment by means of sliding guides. 4. Upper lids. Allow access to the interior of the equipment. The interior of the equipment is divided in four areas. Each one of them is made of an independent and closed metallic cavity. This way the required shielding between them is achieved:

1. Input and power supply area. Located in the back left side of the equipment by the back panel and the left panel. It is closed through an independent upper lid. It includes an extracting fan attached to the back panel which allows incoming air from the front panel through specially designed slots located in this cavity. When required the input channel filter is placed here. 2. RF area. Located by the previous described area, next to the back panel. It is formed by three metallic cavities (named slots) in which up to the three RF processing cards can be inserted. These cavities are closed through an independent lid so that they remain completely shielded. This lid has several holes, necessary to allow the adjustment of the inserted cards. When the equipment is working it is essential that the lid is on and correctly screwed. DC supply and control signal connections are performed through an interconnection card located in the bottom of the cavities. The access to this interconnection card is made by means of a peephole in the lower part of the equipment. 3. Power amplification area. Located on the right side of the equipment, from the front panel to the back panel. It is built up with a big dimensions heat sink with high heat evacuation capacity to which the power amplifiers are attached. Given that all the RF modules placed in this cavity are shielded there is no other lid MECHANICAL DESCRIPTION 36/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 different to the general one. During the servicing tasks, the upper lid can be removed. However, it is essential that when the equipment is functioning the amplifier shield is in place. The heat sink has a fan that takes the air from the front of the equipment. Air is forced to pass through the heat sink wings and finally goes out through the back panel. In order to have access to this fan it is necessary to remove the front panel. 4. Control area. Located in the front left side. It has the control board fixed to the front and the linearity corrector module fixed to the wall by the RF zone. This area has additional space to place other modules, for instance, a reference oscillator. This multiple cavities system separates each one of the functions of the equipment and ensures a high isolation between them. The high shielding avoids radio frequency and therefore instability phenomena. Radiation and susceptibility are very much reduced. Notice that, for maintenance, the equipment can work without having the upper and lower lids on; but that, in these conditions, there might not be possible to guarantee a radiations and susceptibility established specifications. The equipment must not be switched on with the power amplifier shield nor the ones in the RF area removed. fulfilment of the MECHANICAL DESCRIPTION 37/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

Complete block diagram: The elements and connections between them of the whole system are sketched in Figure 10. This schematic does not contain information about the signals transmitted between elements (modules and boards) of the unit. This schematic contains all the input and output connectors of the unit. For clarity purposes, the information of the signals has been divided in three diagrams: RF signals, power supply signals and measurements and control signals. RF Signal block diagram: The path through the modules of the modulated signal containing the broadcasted information is shown individually in this scheme. Frequency and levels are indicated at each point. In case of sample paths, the value of coupling is also noted. The signal levels presented in this scheme are a reference value that must not be taken as an exact value since they are generic values for a Gap-filler unit. When precision adjusting for a signal level is required, the value in the diagram has a tolerance value. Measurement and control block diagram: All the connections between modules and boards containing control and indication information is shown in this block diagram. Also the output/input control Ethernet connector is shown. Power supply block diagram: In this diagram we can see the power supply distribution with the voltage values of each module and board. The voltage indication is presented as a nominal value. For exact value adjusting consult the measurements menu at the front panel control display. These block diagrams are described in the following sections.

04/10/2007 7.1. SIGNAL PATH DESCRIPTION RF input: RF input signals must be connected to the input connector. The input signal is filtered by means of a 4 pole passive filter in order to prepare the down-

conversion input signal. Down-converter move the input signal to IF (the IF signal is inverted since it uses a LO with a higher frequency than the input signal). IF processing: Down-converter also performs SAW filtering of IF signal. IF frequency equalization can be adjusted. Echo-cancellation board processing is situated inside the signal path of the down converter. In order to perform a good A/D conversion, the input level of echo-canceller board must be adjusted accurately to 15dBm. At the output of down-converter a coupler is used to obtain a IF signal sample at the back panel connector. The output of down-converter is connected to linearity corrector module that performs the pre-distortion of the IF signal to obtain a linear behavior of the whole signal path (including the amplification stages.). At the up-converter input, before moving to RF, IF level detection is performed. High level and low level detection is performed. IF frequency equalization can be adjusted at this point. RF conversion: IQ modulator performs agile mixing of the IF signal. With the same LO of the down-conversion the signal is converted to RF frequency again. High rejection of IQ modulator spurious (LO rejection and image band rejection) can be adjusted. After conversion, an electronic attenuator is used to control the output level of the up-converter and, in consequence, the output power of the gap-filler unit. Following stages have fixed gain. This gain can be controlled internally by means a potentiometer or externally by means of I2C communication with the control board. In normal operation the gain is controlled by the control board. A sample of the up-

converter output is connected to the back panel of the unit. Notice that this sample is still a pre-distortionated signal. Quality measurements can not be measured in this point. For CGU-50/HG, after up-converter module a pre-amplification filter is added in order to protect the power amplifier. Amplification stages: The gain of final stages is divided in two amplifiers modules. A high gain driver amplifier is used first. For trouble-shooting purposes a sample is present at the output of this module. This sample is not wired to the back panel and the signal is still not linear. Power amplifier module obtains the desired output power. Output power processing: After amplification stages a coupler is used in order to obtain an output sample at the back panel of the unit. At the same time have a forward and reversed power detectors obtain a voltage indication of both signals. ELECTRONIC DESCRIPTION 50/87 FLO Repeater CGU20-50-100W HG Doc: 47N0137 Edition: 2 Date:

DC conversion. Two outputs are generated, power amplifier power supply voltage and 25.5V for the other boards and modules. Power amplifier supply voltage is 30V for CGU100/HG gap-filler unit. Driver amplifier module and fan units are supplied directly by means of 25.5V output. Interconnection board generates 12V for the clamp module and 24V from where all the remaining boards and modules (except of coupler and detector module) are supplied. Coupler and detector module uses +12V generated by control and measurements board. Consumption of all slot boards are sensed in interconnection board. Figure 17.- Power supply distribution diagram.

(CGU20-50-100/HG FLO embedded web) device is controlled by the corresponding interface description update whenever a software upgrade is performed on the equipment. the 50N0136 software code. Please, ask for 9.1. DISPLAY AND KEYBOARD The user interface has been implemented by means of a four-line retro-illuminated LCD display and a four-button keyboard, both placed in the left side of the front panel of the equipment. The display shows the measurements, settings, and menus, as well as any warning or alarm that might be detected on real-time. Therefore the state of the unit can always be looked up or configured, not only in a remote way, but also locally thanks to the keyboard and the LCD. Figure 19.- User Interface: LCD display + 4-button keyboard. 9.1.1. INFORMATION IN THE DISPLAY Depending on the selected menu or submenu, the information that is displayed on the LCD varies. However, the software has been designed in order to achieve a user-

friendly interface and, in consequence, each of the four lines has a special functionality (which of course depends on each particular screen). Except for the root menu screen, which is somehow particular, the information displayed in the four lines can be summarized the following way:

1. 1st line: displays the name of the menu/submenu. 2. 2nd and 3rd line: can be used whether to display the names of the menus

(as well as its scrollbars), and/or display information (parameters values, status information, process information, etc) in case of a final screen. 3. 4th line: unless it is used to display information (parameters values, status information, process information, etc) in a final screen, the 4th line shows the time, date and the state of the control (REMOTE / LOCAL). In case that CONTROL SOFTWARE DESCRIPTION 60/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 an alarm or warning is detected in the equipment, the 4th line is used to display the alarms and warnings in a rotary way. 9.1.2. KEYBOARD NAVIGATION The 4-button keyboard can be used for navigating through the menu tree as well as to modify any device parameter when needed. As indicated in the silkscreen printing, the name of the four buttons are: ESC, SEL, + and -. These buttons can perform the following actions:

When navigating through menus: Selects a menu, and displays its screen. In other words: descends a level of the tree menu. When editing parameters: Enables the edition of the value of a parameter, or validates and answer when the user is requested for a YES/NO question. When navigating through menus: Unselects a menu, and displays its parent menu screen. In other words: ascends a level of the tree menu. When editing parameters: Cancels the edition of the value of a parameter, or invalidates and answer when the user is requested for a YES/NO question. When navigating through menus: Sets focus to the previous submenu of the actual menu. In other words: ascends a position in the tree menu. When editing parameters: Switches between different possible options or increments a digit in case of editing a numeric value. When navigating through menus: Sets focus to the next submenu of the actual menu. In other words: descends a position in the tree menu. When editing parameters: Switches between different possible options or decrements a digit in case of editing a numeric value. Table 6.- Explanation of the buttons of the keyboard. Please, when navigating along the submenus of a menu with the + and - keys, take into account that the menus layout is not circular (e.g., the last submenu of a menu is not followed by the first submenu of the same menu). This can be clearly seen on screen thanks to the following icons:

The focus is set on the first line of the actual menu and, therefore, there is no previous accessible line. The previous line is accessible. The next line is accessible. The focus is set on the last line of the actual menu and, therefore, there is no following accessible line. Table 7.- Scrollbar icons CONTROL SOFTWARE DESCRIPTION 61/87 9.2. USER INTERFACE MENU FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 The software has been organized in a tree-menu format, so that its operation becomes intuitive and easy-to-use. Once the equipment is switched on, a first boot screen appears on the display, which is shortly after replaced by the root menu screen. From this root menu screen, 3 main menus are available:

MEASUREMENTS MENU: Here, several parameters of the equipment can be inquired:

o Power measures o Voltage measures o Current measures o Temperature measures o General status indicators of the device SERVICE MENU: Can be used to look up the different control settings and parameters, or even adjust them if the equipment is set to local mode. o Control parameters (Remote or local mode, SW version, Language, and RF, LO state) gains. o Output RF AGC parameters: State (ON/OFF), up-converter and output o Up converter parameters: Frequency, gain adjust settings and auto-

calibration option. IP settings: IP and gateway addresses, as well as subnet mask. o o Change profile o Time set and timer consultation. IP STATUS: provides easy and fast access to look up the state of the Ethernet link, as well as to the value of the IP and gateway addresses, and the subnet mask. A more concise explanation of the different screens and settings of the software will be detailed in the next sections. SERVICE NOTE: The LCD screen turns into inactivity mode (i.e., it displays no intensity at all) once there have been no keyboard or remote orders for a period of time of 10 minutes. Once in the sleep mode, the LCD screen will immediately activate again in case of a remote order or a local keyboard change. After the LCD awakes, the root menu screen is shown on the LCD, despite of whichever menu was being shown just before the LCD deactivation. CONTROL SOFTWARE DESCRIPTION 62/87 10.

04/10/2007 11.1. SNMP AGENT IN MIER COMUNICACIONES BROADCAST UNITS. 11.1.1. INTRODUCTION Mier Comunicaciones broadcast units incorporate an Ethernet 10Base-T interface for external management. Through this interface different services and IP protocols are implemented, easing the handling and maintenance of the device. Among these, FTP protocol for a fast and efficient update of the files in the equipment, or telnet for other several services. Some units have implemented a small Web server which allows an easy and intuitive access to the different parameters from the equipment, as well as to act on the same one. The user will only need a computer connected to the network, an explorer with qualified Java, and to know the equipment IP address to accede to the same one through the explorer. The critical options are, as it is done with other protocols, password-protected. Another protocol, implemented optionally in the equipment is SNMP (Simple Network Management Protocol). The SNMP Agent is embedded in the unit, and, by means of SNMP protocol, provides access and control of the basic parameters of the system. The next table gives a relationship between SW versions of the equipment, the embedded SNMP Agent version, and the MIB revision to which it makes reference. Unit Version SNMP Agent Version MIB revision

MIER COMUNICACIONES BROADCAST UNITS MIB DESCRIPTION The MIB (Management Information Base) associated to the broadcast units of MIER Comunicaciones is structured in different folders in a modular way. This MIB is generic, and applies to all compact units (analog and digital transmitters, transposers and gap-fillers). The MIB also implements all the common objects and those that are only specific for some type of equipment. For a specific unit only a subset of these MIB objects will apply, and the rest wont have any meaning for the given unit. Please, review the tables on next sections with the MIB entries and the kind of units they apply to. SNMP MANAGEMENT 71/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 11.1.3. READ AND WRITE COMMUNITIES The SNMP agent has implemented read and write communities associated to the GET and SET actions of SNMP Protocol. These communities are text values. The values are public and private by default. The assigned values to these communities are stored on CHIP.INI file. One way to modify them is editing directly this file and reload it in the unit by means of FTP 11.1.4. TRAPS DESCRIPTION. The Traps have one unique OID and different variable fields incorporating additional information, such as severity degree, object OID that has caused the alarm, sequence number, etc. NOTE: Boldface items in this table only apply to MIB revision 4 and onwards.

(In successive Agent and MIB versions, more traps can be added) An OID to the trap variables, which describes the object that caused this alarm, has been added. Normally, for each trap code there will be an OID field. Nevertheless, for each OID field, there can exist more than one trap code. For instance, codes 7 (LO3 lock SNMP MANAGEMENT 72/87 FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 Alarm) and 8 (unit recovered from an OL3 lock alarm) refer to different states of the same object:

Mierexc2ndConverterPLLLockStatusAlarm ::={ mierExciterAlarmEntry 622 }

11.1.5. HISTORY OF SENT TRAPS SNMP protocol is based on UDP, so it is not connection-oriented. It means that, in case of some transitory problem in the IP transport network or for some reason the SNMP managing was temporarily unavailable, and during this interval the SNMP agent sent some trap to this manager, this one would be lost, and the SNMP Agent would not have any way to know wether this trap has arrived to its destination or not. For that reason, a sequence number and/or index are sent within each trap, which can help to the manager to find out if some trap has been lost between two consecutively received traps. On the other hand, the Agent keeps the last N traps

(the N value can vary depending on the Agent implementation or version) in a buffer or cyclical queue so that if the manager receives 2 traps with non-consecutive sequence numbers, it can always query the SNMP Agent about the N sent traps and thus to recover those ones which probably missed. The buffer or register of the latest sent traps is not persistent (is not saved in non-

volatile memory) therefore will be reinitiated whenever the agent starts. It is also possible to view the latest sent traps through the telnet interface. Each time key L is pressed, the device sends through this interface the latest traps that have been sent. 11.1.6. PARAMETERS CONFIGURATION OF THE SNMP AGENT Of general way, the configurable parameters of SNMP agent in the unit reside in the [

SNMPD ] section of CHIP.INI file. Some examples of these parameters are:

(Not used for SNMP) It allows to define the Trap Receivers, IP adresses

(up to 5) of the managers where the traps are sent to. It is possible to have less than 5 entries (or any). IP address of the server which implements the TP protocol to allow the agent to recover date/time when start-up. If the entry doesnt exist (or its value is 0.0.0.0), the agent wont do any action. If the Agent synchronizes with the Time Server when it starts, it will get its time reference (plus the OFFSET) and modify its own time according to this value Offset, in hours, from the local time to the time given by the Time Server. If this value does not exist, it will be assumed as 0. When value=1 the SNMP agent will keep on sending traps even if the unit is in local mode, or it will stop sending traps (value=2), but the ones which indicate change from REMOTE to LOCAL and visa-versa. Bit-Mask value which allows to individually activate or block the sending of some traps. It is described individually later. NOTE: The assigned values to the CHIP.INI entries, even when they are text chains, are without simple nor double quotation-marks. IMPORTANT: Please never modify other contained text chains in the CHIP.INI file, because they can be for internal use and it could cause a fatal error in the device. Trap receivers. In SNMP protocol, the Agent sends the answers to SNMP requests (if the communities are correct) to IP addresses where the manager who sent the requests is. When sending traps, the Agent must have a list of adressees for this trap, because these ones have being originated by the same agent asynchronously. This list can store up to 5 different IP addresses, and it is stored in CHIP.INI file. It can also be edited and loaded through FTP. Enabling/Disabling traps on an individual basis By means of the TrapMaskDisable object, the user can assign a mask that allows enable or disable each one of the possible traps specifics of the system. The object syntax is a bit-mask, for this reason each trap could be disabled if the corresponding bit to its position (starting in the less representative bit) is on.

04/10/2007 11.3. RECEIVED TRAPS AND ITS INTERPRETATION WITHIN THE FRAMEWORK OF GAP-FILLER UNIT MANAGEMENT In this section the SNMP event adquisition system will be explained. Although SNMP operates in the same way in all the broadcast units of Mier Comunicaciones, this process will be described using a gapfiller unit as an example. 11.3.1. THE EVENT ACQUISITION SYSTEM The system CPU is acquiring a set of indications which some of them can launch an alarm and in some cases, an SNMP trap. This polling is performed in an interval near to 1 second; therefore if an indication changes inside the polling interval, the CPU wont indicate the corresponding alarm. In a similar way, the SNMP agent which is built-in in the Control Board performs an inner acquisition of the CPUs indications. This polling is performed in an interval of 2/3 seconds. It can be also possible that the SNMP agent not have an alarm information which has happened between the polling intervals and hence the corresponding trap wont be sent because the SNMP agent has no report about this. Therefore its possible to have a single trap corresponding to a problem in the equipment which has generated multiple alarms. In response to these alarms the equipment has performed some actions and, due to these actions, all the alarms have been disappeared except one. All these processes between the polling intervals have no significance and are in consequence transparent to the SNMP manager. In the following section a list of possible alarms and traps is enclosed. Also the equipment protection routines to each situation are described. The actions to be done further on in response to every specific alarm are described in the Troubleshooting chapter inside the Service Manual of the unit. 11.3.2. TRAPS WITH ALARM RELATIONSHIP In the Software version described1, there are 24 SNMP traps available. All these are grouped in pairs, normally in an ON/OFF way. All the pairs have a common OID corresponding to one field of the MIB exciter alarm tables. The description of the alarm-related traps is divided in three cases:

a) Output power trap b) Traps related directly to a service cut c) Traps unrelated to a service cut 1 Software code: 50N0097, Version: 1S51 SNMP MANAGEMENT 80/87 OUTPUT POWER TRAP 3.- "Output power error"

4.- "Output power OK"

FLO Repeater CGU20-50-100W HG Doc: 47N0208 Edition: 1 Date:

04/10/2007 The typical situation is to receive a cause trap followed by an Output Power trap. In this case its easy to know what has happened to the unit. In case only the trap "Output power error" appears, two possible causes may generate this situation:

a) A quick response of a multiple-alarmed equipment that implies the quick correction of all the alarms except the output power alarm. The errors that can generate a situation like this may be:

a. Input signal error. b. Adaptative filter error (abrupt change of echo conditions). c. Output return loss error (output power attenuation). d. 2nd converter PLL unlocked. b) An equipment failure which is not related to an SNMP trap but with an equipment alarm:

o An IF signal cut (due to down converter, linearity corrector, clamp amplifier or up converter peak detector). o An amplifier failure: both power or driver amplifiers. The basic difference between both cases is that in the first one, the equipment will recover the output power in a short interval of time, normally the time that each Gap-

Filler spends on reach the nominal output power once the cut-off cause has recovered (When the IF level at the Up converter is OK, this performs a soft power start-up which can be observed directly with an Spectrum Analyzer or by means of the Control AGC menu in the unit display). TRAPS RELATED DIRECTLY TO A SERVICE CUT These situations generate as well as the own trap, an Output Power Error trap. Normally when the problem which has caused the service cut disappears, as has been explained in the Output Power case, the power is gradually recovered. 7.- "2nd converter PLL unlocked"

8.- "2nd converter PLL locked"

21.- "Input signal error"

22.- "Input signal OK"

04/10/2007 When trap 21 is received, the unit usually sends also the trap 9 (Adaptative Filter Error), depending on the polling interval (as explained in previous section). TRAPS UNRELATED TO A SERVICE CUT 5.- "Output return loss error"

6.- "Output return loss OK"

In this case the IF level is attenuated in order to protect the unit. The Gap-Filler gives as power as it can (on the condition that the Return Loss be greater than 6dB with regard to output power). 9.- "Adaptative filter error"

10.- "Adaptative filter OK"

This trap can be generated in case of MK-II board failure (traps 9 and 3 will be received) or in case of a failure before the Echo Canceller input, normally an Input Power Error (traps 9, 3 and 21 will be received). In case that the MK-II board works properly (with the Echo Cancellation ON) and the SNMP manager receives traps 3 and 9 (not 21), there exists a problem inside the Down Converter board, typically a cavity filter disadjustment, a bad jumper configuration, or a mixer failure. Before doing anything, please check the inputs to the Down Converter (RF input and OL input from Up Converter DDS). 15.- "External reference input error"

16.- "External reference input OK"

This trap is only received when the OR alarm is not deactivated, that is, in the Control Submenu, the OR must be ORon (when changing parameters into the Service Menu, a Local Control mode must be selected). Note, as in all other cases, that the traps are only sent in case of a State change; in this case, if the external reference are not connected when the unit is switched on, there wont be a trap #15. 17.- "Input air temperature error"

18.- "Input air temperature OK"

In this case the unit reports an alarm but not cut off the output power. 19.- "Amplifier temperature error"

20.- "Amplifier temperature OK"

04/10/2007 Only in the 100Wrms unit, the unit attenuates 2dB/C that exceeds 90C, with a maximum attenuation of 10dB. 11.3.3. TRAPS WITH NO ALARM RELATIONSHIP 1.- "Bus error"

2.- "Bus OK"

This only applies to the equipments which has been provided with an external SNMP adaptor (only in case of control board 80A0767) 11.- "Cannot connect to time server"

12.- "Restablished connection to time server."

This is only used when synchronization with a time server is required in the moment of the start-up. 13.- "Device is in Local Control mode."

14.- "Device is in Remote Control mode."

Note if TRAPINHIBIT=2 the unit will stop sending traps in case of changing to Local mode. 23.- User initiated command: RFOFF 24.- User initiated command: RFON Obviously when the trap 23 is received, there will be an Output Power Error trap.

04/10/2007 11.3.4. MANAGEMENT RECOMMENDATIONS When a trap is received, is very useful to get a picture of all parameters by means of an SNMP get commands. For example, in case of Output Power Error, you can get, as an example:

1.3.6.1.4.1.13531.2.10.1.1.1000 1.3.6.1.4.1.13531.2.10.1.1.220.1 1.3.6.1.4.1.13531.2.10.1.1.221.1 1.3.6.1.4.1.13531.2.10.1.1.300.1 1.3.6.1.4.1.13531.2.10.1.1.400.1 1.3.6.1.4.1.13531.2.10.1.1.401.1 1.3.6.1.4.1.13531.2.10.1.1.600.1 1.3.6.1.4.1.13531.2.10.1.1.750.1
