Part one includes Chapter 1 through Chapter 5. The OMT32 software is described in part two of the manual, starting with Chapter 6, OMT32 Installation. User’s Manual VD202 90/EN Rev. 1A 1999-07 ALLGON System AB AR Repeaters & OMT32 Hardware – Safety 1. Safety Any personnel involved in installation, operation or service of the Allgon repeaters must understand and obey the following: • Allgon repeaters are designed to receive and amplify signals from one or more base stations and retransmit the signals to one or more mobile stations. Also, the repeaters are designed to receive signals from one or more mobile stations, amplify and retransmit to the base stations. The repeaters must be used exclusively for these purposes and nothing else. • Repeaters supplied from the mains must be connected to grounded outlets and in conformity with any local regulations. • The power supply unit in repeaters supplied from the mains contains dangerous voltage level, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters. Authorized service personnel only are allowed to service repeaters while the mains is switched on. • The repeater cover must be secured in opened position, e.g. by tying it up, at outdoor repeater work. Otherwise, the cover can be closed by the wind and cause your fingers getting pinched or your head being hit. • When working on a repeater on high ground, e.g. on a mast or pole, be careful not to drop parts or the entire repeater. Falling parts can cause serious personal injury. • Any repeater, including this repeater, will generate radio signals and thereby give rise to electromagnetic fields that may be hazardous to the health of any person who is extensively exposed to the signals at the immediate proximity of the repeater and the repeater antennas. • The CHA channel board power transistors, the PA amplifier board BERYLLIUM OXIDE power transistors, and the combiners (CMB) contain beryllium oxide (BeO) that is poisonous if present as dust or smoke which can be inhaled. The power transistors mentioned are mounted with two screws as opposed to other transistors. Do not file, grind, machine, or treat these parts with acid. Warning signs are applied on boards and units that contain beryllium oxide. These warning signs are shown in the next section. • The coaxial cable insulation is made of PTFE, polytetrafluoro ethylene, HYDROGEN FLUORIDE that gives off small amounts of hydrogen fluoride when heated. Hydrogen fluoride is poisonous. Do not use heating tools when stripping off coaxial cable insulation. No particular measures are to be taken in case of fire because the emitted concentration of hydrogen fluoride is very low. • A lithium battery is permanently mounted on the CU board. Due to the risk of explosion, this battery must not be removed from the board. In case of battery malfunction, replace the CU board. The old CU board can be sent to Allgon for repair. User’s Manual VD202 90/EN Rev. 1A 1999-07 1-1 ALLGON System AB AR Repeaters & OMT32 Hardware – Safety Warning Signs The following warning signs must be observed and be kept clean and readable. Beryllium oxide This warning sign is applied on boards and units which contain beryllium oxide parts. Beryllium oxide hazard BERYLLIUM OXIDE (Toxic) used in equipment see instruction book This warning sign is applied at the bottom, inside the cabinet, below the power supply unit. The previous section details parts containing beryllium oxide and how to avoid dangerous dealing with these parts. Static Electricity Static electricity means no risk of personal injury but it can severely damage essential parts of the repeater, if not handled carefully. Parts on the printed circuit boards as well as other parts in the repeater are sensitive to electrostatic discharge. Never touch printed circuit boards or uninsulated conductor surfaces unless absolutely necessary. If you must handle printed circuit boards or uninsulated conductor surfaces, use ESD protective equipment, or first touch the repeater chassis with your hand and then do not move your feet on the floor. Never let your clothes touch printed circuit boards or uninsulated conductor surfaces. Always store printed circuit boards in ESD-safe bags. User’s Manual VD202 90/EN Rev. 1A 1999-07 1-2 ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction 2. Introduction Figure 2-1. Allgon AR Repeater Allgon repeaters are used to fill out uncovered areas in cellular mobile systems, such as base station fringe areas, road tunnels, business and industrial buildings, etc. A repeater receives signals from a base station, amplifies and retransmits the signals to mobile stations. Also it receives, amplifies and retransmits signals in the opposite direction. Both directions are served simultaneously. To be able to receive and transmit signals in both directions, the repeater is connected to a donor antenna directed towards the base station and to a service antenna directed towards the area to be covered. Control of the repeaters is performed using a desktop or notebook loaded with the Allgon OMT32, Operation and Maintenance Terminal, which can communicate with the repeaters, either locally or remotely via modem. Remote operation can be performed either via a traditional telephone line or via a mobile phone that can be installed inside the repeater. To be able to control many Allgon AR repeaters in common, there is an Allgon OMS, Operation and Maintenance System. The repeaters and the OMT32 is described in this manual. The OMS is described in the Advanced Repeater OMS, User’s Manual. User’s Manual VD202 90/EN Rev. 1A 1999-07 2-1 ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction Repeater Types The following repeater types are available: • • • • • Channel selective GSM repeater Channel selective CDMA repeater Band selective repeater with fixed band width Band selective repeater with adjustable band width Combined repeater In the OMT32, the channel selective 900, 1800, and 1900 systems are called GSM, DCS and PCS respectively, even though these systems may have different names in other parts of the world. Channel selective GSM repeater A channel selective GSM repeater can be equipped with two, four, six or eight channels. This repeater type is used for channel selective systems, such as GSM, DCS/PCN and GSM 1900 (PCS). Channel selective CDMA repeater A channel selective CDMA repeater can be equipped with one or two channels. This repeater type is used for digital code division systems in accordance with IS-95 or J-std-008 standard. Band selective repeater, fixed band width A band selective repeater with fixed band width has fixed filters for a certain band width. This repeater type is used for analog or digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA. Band selective repeater, adjustable band width A band selective repeater with adjustable band width has filters that can be set to various band widths. This repeater type is used for analog or digital systems, such as NMT, TACS/ETACS, AMPS, DAMPS and CDMA. Combined repeater Some of the above mentioned types can be combined in the same repeater chassis and be in operation in parallel. User’s Manual VD202 90/EN Rev. 1A 1999-07 2-2 ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction Using Repeaters In areas where the radio signal propagation is poor repeaters can be used to fill out those areas which are not covered by the base station. The following scenarios are examples on this: Sports arenas Fair halls Large shopping centres Road and railway tunnels Indoors in buildings with metal or concrete walls Other examples where repeaters can be used to increase the coverage are: - Shaded areas - Fringe coverage areas In areas where the traffic intensity is low, it is not cost efficient to install a base station. An Allgon repeater, which can be installed with a minimum of investments, is a much better solution. You save installation costs as well as operational costs. Examples of using repeaters Two examples are described in the following sections. An outdoor example in a shaded valley and an indoor example in a sports arena. User’s Manual VD202 90/EN Rev. 1A 1999-07 2-3 ALLGON System AB AR Repeaters & OMT32 Hardware – Introduction Shaded Area A valley is shaded by hills. There is a base station 5 kilometers away, but the lowest signal strength in the valley is less than –100dBm. A mast used for other purposes is available for a repeater installation. The mast height is 42 meter and it is located on a hill. The scenario is illustrated in Figure 2-2. Donor antenna Service antenna Figure 2-2. Repeater coverage of shaded area The donor antenna of the repeater was mounted at the top of the mast and the service antenna was mounted at the half mast. The antenna isolation was measured to over 100dB. The repeater was set to max. 80dB gain.

User’s Manual VD202 90/EN Rev. 1A 1999-07 2-5 ALLGON System AB AR Repeaters & OMT32 Hardware – Installation 3. Installation Before installation, read carefully Chapter 1, Safety. Siting the Repeater Allgon repeaters are designed for outdoor usage. However, humidity and temperature changes may have affect on the reliability. A preferable site for the repeater is thus indoor, in a tempered and ventilated room. Sunshine If a repeater is placed outdoor and can be exposed to direct sunshine, it is essential that the air can circulate around the repeater with no obstacle. The operating temperature must not exceed +55°C due to sunshine exposure. A shelter must be used in this case. Shelter Allgon repeaters are designed with a weather proof outdoor case that can be mounted without any kind of shelter from rain, snow or hail. If a repeater is to be opened on the site when raining, snowing, or hailing there must be some kind of permanent or temporary shelter. This is applicable to gentle rainfall, snowfall or hail. Limitations for very bad weather is found in the next section. Allgon can provide a shelter designed for these repeaters. This shelter is shown in Figure 3-1. Outdoor Installation and Service Limitations Sited outdoors, the repeater must not be opened for installation or service at bad weather, such as: User’s Manual VD202 90/EN Intense rainfall, snowfall or hail Storm or high wind Extremely low or high temperature High humidity of the air Rev. 1A 1999-07 3-1 ALLGON System AB AR Repeaters & OMT32 Hardware – Installation Dimensions and Weights The dimensions of the repeater, including the mounting bracket, is shown in Figure 3-1.

Rev. 1A 1999-07 4-3 ALLGON System AB AR Repeaters & OMT32 Hardware – Commissioning Measuring the Output Power Level Uplink and downlink output power test ports are found on the directional couplers (DC) at the MS and BS antenna connectors. These test ports are marked TEST –30dB (see Figure 4-1) and are intended for measuring using e.g. a spectrum analyzer. The coupling is –30dB approximately. There is no directivity in these test ports, i.e. both uplink and downlink signal can be measured. Voltage Supply Testpoints A number of voltage supply testpoints are available in the repeater. These testpoints are named U7A - U7F for the 7V supply voltages and U26 for the 26V or 10V supply voltage (26V or 10V depending on the repeater type). A standard multi-meter can be used on these testpoints. The testpoints are found on the DIA board in the repeater cabinet. The testpoint positions on the DIA board is detailed in the Board and Unit Descriptions section in Chapter 5. If the repeater is equipped with a second PSU, e.g. for combined channel/band selective operation, the same set of testpoints are found on the cover DIA board as well. Repeater Adjustment The repeater is now ready to be adjusted in accordance with the site conditions and system performance requirements. Pay especial attention to the antenna isolation described in the Operational Status section in Chapter 10. User’s Manual VD202 90/EN Rev. 1A 1999-07 4-4 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description 5. Functional Description Allgon repeaters work as bi-directional on-frequency amplifiers. A repeater receives, amplifies, and retransmits signals downlink and uplink simultaneously, i.e. from the base station via the repeater to the mobile stations and from the mobile stations via the repeater to the base station. The repeater is connected to a BS antenna, directed towards the base station, and to a MS antenna directed towards the area to be covered. These antennas are connected to the repeater with N type male connectors. To prevent instability due to poor antenna isolation, a built-in antenna isolation supervision feature reduces the gain level automatically when poor antenna isolation is detected. The Allgon repeaters are controlled by powerful microprocessors. Alarm and operational LEDs are visible on the repeater front. The repeater works with convection cooling without fan. Operational parameters such as gain, channel number, power levels, etc. are set using a desktop or notebook and the Allgon OMT32, which communicate, locally or remotely via modem, with the repeater control unit (CU). Remote operation is performed using a telephone line or a built-in mobile phone equipped with a data interface. User’s Manual VD202 90/EN Rev. 1A 1999-07 5-1 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description Repeater Design The repeater is housed in a cast aluminium chassis that is waterproof, class IP65, for outdoor use. The chassis has a design suited for outdoor use as well as indoor use. The chassis consists of a cabinet and a cover joined with hinges. The cabinet contains the repeater circuitry. The cover can either be a thin cover or a large cover. The latter consists of another cabinet which can be used as an empty cover or be equipped as an independent repeater system. The cover has two external LEDs for operation and alarm indication. The cabinet as well as a large cover can be equipped for channel selective operation or band selective operation. A combined repeater is normally equipped for channel selective operation in the cabinet and band selective operation in the cover. Different amplifier boards are used to get the various operations (see below). The amplifier boards are individually shielded and located under metal cover sheets which can be folded out. Channel selective GSM amplifier boards Channel selective GSM repeaters can handle up to eight repeater channels (four if the CU part number is K103/1). For every even number of repeater channels, two CHA amplifier boards are required in the repeater, one CHA board for uplink signaling and one board for downlink signaling. Each repeater channel is allocated to a radio channel or switched off. In a GSM type TDMA system (GSM, EGSM, DCS1800 or PCS1900), one repeater channel can handle eight calls (sixteen if half-rate encoding is used). Channel selective CDMA amplifier boards Current CDMA repeaters can handle two CDMA repeater channels. For every even number of repeater channels, two CSA amplifier boards and two PA amplifier boards are required in the repeater, one pair of CSA/PA boards for uplink signaling and one pair for downlink signaling. Each repeater channel is allocated to a radio channel or switched off. Band selective amplifier boards Band selective repeaters can handle one wide band repeater channel. The band width is either fixed or adjustable (fixed for 900MHz repeaters only). A band selective repeater channel requires two BSA boards and two PA amplifier boards in the repeater. One pair of BSA/PA boards for uplink signaling and one pair for downlink signaling. User’s Manual VD202 90/EN Rev. 1A 1999-07 5-2 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description Other boards In addition to the channel/band selective boards, the repeater contains: • DIA Distribution board, which is a board on which all other boards and units are connected to.

Some of the most important features and functions are described below. The main signal paths for the repeater types are described under the block diagrams. Downlink The downlink signal path, i.e. from the base station through the repeater to the mobile station, is described for channel selective GSM operation, channel selective CDMA operation, and band selective operation under the block diagrams on the following pages. Uplink The uplink signal path, i.e. from the mobile station through the repeater to the base station, is identical to the downlink path the other way round. Only some levels and component values differ. Repeater Setup The repeater parameters can be set locally by means of a desktop or notebook loaded with the OMT32 software (or the OMS software). The PC or notebook is connected to the CU via the P31 serial RS-232 PC port (see Figure 5-5, Figure 5-6 and Figure 5-7). The repeater parameters can also be set remotely by means of a phone (mobile or via a telephone line) and a modem connected to the CU board via the P32 modem serial RS-232 port (see Figure 5-5, Figure 5-6 and Figure 5-7). User’s Manual VD202 90/EN Rev. 1A 1999-07 5-8 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description Alarm Alarm signals from external sensors are received by the ALI board, which forwards the alarm signals to the CU board. The software on the CU board is able to activate acoustic or visual alarm or direct the alarm to the P33 alarm RS-232 port to be forwarded, via modem and telephone, to an OMT32/PC (or OMS/PC) located in an operation and maintenance central. Alarms can be configured from an OMT32/PC (or from an OMS/PC).

Block diagram, channel selective repeater Figure 5-5 shows a block diagram of a channel selective repeater with four bi-directional channels. This diagram is applicable to repeaters for the GSM, DCS/PCN and GSM 1900 (PCS) systems. Downlink The signal from the base station is received via the repeater BS antenna and is then forwarded through a directional coupler (DC). The signal passes a duplex filter (DPX), is amplified in a low noise amplifier (LNA), and enters the channel boards (CHA), which have two parallel channels each. User’s Manual VD202 90/EN Rev. 1A 1999-07 5 - 10 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description The first mixer stage on the CHA amplifier board, which is controlled by a synthesizer, converts the received frequency down to the IF frequency. The signal is then filtered by a SAW bandpass filter and, not shown in the figure, amplified before it is fed to the second mixer stage, controlled by the same synthesizer as the previous one, for converting back to the original frequency. The output signal from the mixer is then amplified in the power amplifier and fed to a combiner, which combines the signals from the two channels on the channel board. The output signal passes a combiner (CMB), a duplex filter (DPX), and a directional coupler (DC), before it is fed to the repeater MS antenna.

The following power amplifier is controlled by the CU. The output gain can be reduced to avoid instability due to poor antenna isolation. The output signal from the amplifier is fed to a combiner, which combines the signals from the two channels on the channel board. A detector on the PA board measures continuously the output level. The signal from this detector is used by the automatic gain control, AGC, to supervise and, if necessary, reduce the output power to keep it under a maximum level. The AGC gain control affects all the amplification stages. The output signal passes a duplex filter (DPX) and a directional coupler (DC) before it is fed to the repeater MS antenna.

User’s Manual VD202 90/EN Rev. 1A 1999-07 5 - 23 ALLGON System AB AR Repeaters & OMT32 Hardware – Functional Description CU Control Unit Board The CU board is the central board in the repeater, located in the repeater cabinet. The CU board contains a microprocessor, main memory, flash memory for the CU software, EEPROM memory for parameters, memory for the event log and statistics, a REFO reference oscillator, ports for local and remote communication, battery powered real-time clock, etc. The CU board is used to supervise and control operational parameters such as gain control, channel handling, etc. The CU takes care of alarms and the event log, password and logon, and many other procedures. The CU is also a control interface when using an OMT32/PC or an OMS/PC locally or remotely via modem. The CU software can be downloaded from an OMT32/PC or OMS/PC either locally or remotely via modem. The real-time clock on the CU board is used for alarm and for the event log. There are currently two CU board variants: K103/1 and K103/2. CU board and CU software part #s K103/1 CU board (old) K103/2 CU board (current) CU board K103/1 can be run with the SA102 01/2 CU software. This board can store one version of CU software. The repeater will always boot on this software version. CU board K103/2 can be run with either the old SA102 01/2 CU software or the current SA102 02/1 or SA102 02/2 CU software. This board can store two versions of CU software, located in segment 1 and segment 2 of the flash memory as Application 1 and Application 2. The repeater will boot on that software which is set as Primary (description of Primary application is found in the CU Revision Manager section in Chapter 10). Compatibility for CU boards and CU software is detailed in the next section. Connection The CU board is connected to the DIA board via the P2 port. Caution A lithium battery is permanently mounted on the CU board. Due to the risk of explosion, this battery must not be removed from the board. In case of battery malfunction, replace the CU board. The old CU board can be sent to Allgon for repair.

User’s Manual VD202 90/EN Rev. 1A 1999-07 9-5 ALLGON System AB AR Repeaters & OMT32 Software – OMT32 Features Command Line Interface The Command Line Interface, CLI, is provided as a quick way of communicating with a connected repeater. Rather than using the normal Windows dialog boxes the user can interact with the repeater more directly. The Command Line Interface feature does not check whether entered values are within permitted range or not. So, you MUST know the system very well before setting gain and power levels using the Command Line Interface. The CLI provides several advantages: • Users accustomed to a keyboard based operating system do not have to adjust immediately to an entirely novel system. • Single parameters can be set. • Without touching the mouse, the experienced user can perform operations quicker. • Using the CLI prevents the screen from getting clogged up with lots of windows. • Using the CLI is more memory efficient. If the CLI is iconized, then double-click the Command Line Interface icon or select the Command Line Interface option in the Advanced menu. Commands can be entered on the command line like this: By clicking the last entered commands can be reselected, edited and entered again. A command list with command syntax is found below. Command Syntax The following command syntax is valid for the Command Line Interface: MAIN_COMMAND-SUB_COMMAND [:PAR1, PAR2, ...]; Note that each line must be ended with a semicolon (;). If a command is entered with an incorrect syntax, an error message with a mismatch explanation is shown.

Those channel numbers which were selected in the configuration window (page 10-6) are shown on the buttons. Only CHA boards present in the repeater are shown with button numbers. CHA boards not present are shown as non-numbered buttons. Specific Status Active GSM channel Selected channel number for which the specific information is shown. Mode The current operational mode, which can be: START UP System startup. Normal startup time is 10 - 20 seconds after the mains is switched on. OPERATE Selected channel is in operation. BLOCK Selected channel is not in operation. An error may have occurred. OFF Selected channel is set to inactive in the configuration window (page 10-6). Gain set to Uplink and downlink gain set in the configuration window (page 10-6). Control to Calculated uplink and downlink setpoint values based on the values in the Gain set to field. Normally, they coincide with the Gain set to values. User’s Manual VD202 90/EN Rev. 1A 1999-07 10 - 15 ALLGON System AB AR Repeaters & OMT32 Software – Repeater Operations Used gain Actual momentary gain for the uplink and downlink transmission. The gain may differ from the setpoint value due to poor antenna isolation. An antenna isolation test feature regulates the gain as follows: - After powering up, resetting or updating, the gain is increased to 13dB above the Control to level (see Figure 10-8). 93dB Control to 80dB Figure 10-8. Antenna isolation margin test The purpose of this 13dB ’over-gain’ is to test if there is a 13dB antenna isolation margin. The gain increase can be seen in the Control to and Used gain fields. - If no instability due to poor antenna isolation is detected during the antenna isolation test, the gain is decreased to the Control to level after 30 sec. Instability 85dB Control to 80dB 72dB 60 min. Figure 10-9. Gain regulation at poor antenna isolation - If instability due to poor antenna isolation is detected during the antenna isolation test, the gain is decreased to a level 13dB below the lowest detected poor antenna isolation level (see Figure 10-9). Warning alarm is activated when instability is detected and Ceasing when the instability has ceased. - The decreased gain level is kept for the next 60 minutes. Then, a new antenna isolation margin test is performed. User’s Manual VD202 90/EN Rev. 1A 1999-07 10 - 16 ALLGON System AB AR Repeaters & OMT32 Software – Repeater Operations Output gain regulation is performed as soon as poor antenna isolation is detected during operation. If instability due to poor antenna isolation is detected at the lowest output gain, the channel is blocked and BLOCK mode is indicated in the status window. Error alarm is activated when instability is detected and Ceasing when the instability has ceased. A constant CW signal in the GSM frequency band is a ’jammer’ which may be harmful to the cellular system. A BTS might, in worst case, be disabled. The Allgon repeaters detect, however, strong CW signals. If a constant CW signal is detected (channel board test point Power 1 or Power 2 >27dBm), the channel is blocked and BLOCK mode is indicated in the status window. Error alarm is activated when the channel is blocked and Ceasing when the blocking has ceased. Antenna isolation test and CW signal strength test are performed in the uplink path. Gain regulation is then performed for uplink as well as downlink using the uplink levels. Antenna isolation test is a valuable feature to reveal isolation problems when installing repeaters. Also, it is very useful when making site specific repeater adjustments such as antenna configuration (i.e. donor and service antenna vertical and horizontal positions, beam alignment, and gain). The antenna isolation test is also useful to reveal other environmental problems that must be considered, e.g. reflections from buildings, masts, traffic, etc. After performing the antenna isolation test, set the repeater gain (Gain set to) to the value obtained (13dB under the instability level). The repeater will then work with a safe gain margin to avoid instability. It is not recommended to use the repeater isolation test in an instable environment to automatically and continuously adjust the gain from the gain set by the operator.

After a following reboot, the downloaded application can be the Current application. The download process can be performed either locally or remotely. If incorrect software is downloaded, or the download process is interrupted, the repeater may be blocked and, in worst case, damaged. If this happens when the process is remotely controlled, a visit to the repeater site will be necessary. If the repeater is damaged, it might be necessary to replace the CU board. Avoid downloading CU software to the primary area because an interrupted process will result in an incomplete CU software, on which the repeater will not be able to reboot. Download the CU software as follows: 1. If the software to be downloaded is stored on a floppy disk, insert the disk in the disk drive. 2. Click the Update 1 or Update 2 button to download the software as Application 1 or Application 2 respectively. 3. Select software file to be downloaded: Figure 10-26.

All alarms are classified in the following levels depending on the extent of malfunction the alarms cause. Alarm Levels None An event that is not detrimental to the repeater performance. None alarms will never be reported. If no alarm is active, None is indicated e.g. in the operational status window. Warning An alarm level that decreases the repeater performance somewhat. A Warning alarm is not a serious alarm. It can be caused by poor antenna isolation, low traffic activity, etc. Error An event indicating that a part of the repeater is not functioning. An Error alarm is a serious alarm. It can be caused by a synthesizer fault, external alarm, etc. Critical An event that makes the entire repeater cease to function. A Critical alarm is a very serious alarm. It can be caused by a mains breakdown, external alarm such as fire, etc. Ceasing An event that resets a previous alarm, i.e. the event when the cause of the alarm ceased. Ceasing is e.g. applicable to an antenna isolation alarm, which after some time can be ceased if poor antenna isolation is no longer detected. Alarm indication Alarms are indicated with a LED on the repeater front and can be transferred to a locally or remotely connected OMT32. The alarm LED indication is reset by a power failure. Combined repeaters indicate alarms for both the repeater units if an alarm has been activated in either of the units. User’s Manual VD202 90/EN Rev. 1A 1999-07 11 - 2 ALLGON System AB AR Repeaters & OMT32 Software – Alarms and Events Internal and External Alarms There are a number of internal alarms and four external alarm inputs. The internal alarms have fixed alarm levels. They are listed on page 11-14. The external alarm inputs, EAL1 - EAL4, can be configured for various alarm levels and alarm purposes in the Alarm Configuration window (description on page 11-4). Some of the alarm input purposes are described below. EAL1 The EAL1 external alarm input can also be used for mains breakdown alarm. This is further detailed in the Mains Breakdown Relay section in Chapter 3. EAL2 The EAL2 external alarm input can also be used for battery backup alarm. EAL3 The EAL3 external alarm input can also be used for fiber optics alarm, provided the Fiber Optic OMT software is used. EAL4 The EAL4 external alarm input can also be used for an alarm which is activated if the repeater door is open. External alarm Ceasing The external alarm inputs can be selected with or without Ceasing. • With ceasing, e.g. Warning w ceasing, means that activated alarms as well as ceased alarms are reported to the OMT32. The latter as Ceasing. • Without Ceasing, e.g. Warning w/o ceasing, means that an activated alarm will be reported to the OMT32. When the cause of the alarm has ceased, the event is assigned the None level. User’s Manual VD202 90/EN Rev. 1A 1999-07 11 - 3 ALLGON System AB AR Repeaters & OMT32 Software – Alarms and Events Alarm Configuration The external alarms EAL1 - EAL4, also described in the P33 Alarm Port section in Chapter 3, can be configured in a dialog box opened by selecting the Alarm Configuration option in the Repeater Preferences menu.

Troubleshooting This chapter contains the following sections: • Active alarm, page 12-2 What to do when an active alarm is generated • Modem debug tools, page 12-4 Fault tracing tools for troubleshooting the OMT modem and the repeater modem. • R2R, communication problem, page 12-5 Verification of the link communication speed. • R2R, advanced node configuration, page 12-6 Fault tracing tool for advanced troubleshooting. Important Before opening the repeater for service or repair, read carefully the entire Chapter 1, Safety, and Outdoor Installation and Service Limitations in Chapter 3. Authorized personnel only are allowed to dismantle any part of the repeater at the site. To open the repeater, use a 5mm Allen key (6mm for older repeaters). Power Failure in General As the entire parameter setting and channel information is stored in an EEPROM in the repeater, all parameter and channel information remains intact after a power failure or turn off. User’s Manual VD202 90/EN Rev. 1A 1999-07 12 - 1 ALLGON System AB AR Repeaters & OMT32 Troubleshooting Active Alarm This section describes what to do when an active alarm is generated. Power supply check • Check the front LED to see if the repeater has power or not. If it has, go to the Other faults section below. If it has not, proceed with the Power failure alarm section. Power failure alarm • Check the mains outlet and the mains cable to the PSU. • If the PSU has power but the repeater has not, the PSU is faulty. • Replace the PSU as follows: DC DC DPX DPX TEST TEST -30 dB -30 dB MS -20 dB MS -20 dB ANT ANT Figure 12-1. Replacing the PSU 1. 2. 3. 4. User’s Manual VD202 90/EN Remove the mains plug (’1’ in Figure 12-1) from the PSU. Disconnect the two connectors (2) on the PSU. Loosen the three fixing screws (3) using a 5mm Allen key. Remove the PSU from the repeater and replace it. Rev. 1A 1999-07 12 - 2 ALLGON System AB AR Repeaters & OMT32 Troubleshooting Other faults Open the repeater cover and connect an OMT32/PC to the repeater. Open the Repeater Event Log and check the cause of the alarm. • If an antenna isolation alarm is indicated, the antenna isolation should be measured. It should be 10dB - 15dB higher than the repeater gain. Check the antenna installation to ensure that nothing has happened to it. If there is a permanent degradation of the antenna isolation, lower the gain to 15dB below the measured antenna isolation. Make an alarm reset. • If the alarm is activated by an external alarm input, then remove the cause of the alarm. • If the alarm is indicated as RF blocking, then an external strong CW signal can be the cause of the alarm. The CW signal is described in the Channel Selective GSM Repeater section under Operational Status in Chapter 10. • If a PSU alarm is activated which appears again, then the PSU should be replaced. • If the alarm is internal and appears again, then a fault has probably occurred in the repeater. Try to trace which unit has activated the alarm and the type of the alarm. In most cases, the unit and fault type can be detected. • As the last resort, if nothing else helps, remove the repeater for service.

If this repeater is to use repeater NU 1 and NU 2 when the own communication fails, then these network units are added to the list in Figure 13-8. Now, the list contains three repeaters, NU 0, NU 1 and NU 2. The ’Try up to’ box sets the number of attempts to report an alarm before giving up. The settings in Figure 13-8 will, if busy line or no answer, result in the following call attempt cycle before giving up: NU 0 - NU 1 - NU 2 - NU 0 - NU 1 - giving up. This makes 5 attempts in the order set in the table. The cycle order can be changed by selecting a network unit and clicking the Move Up or Move Down buttons. Modem 0 means the first modem for the repeater, but no repeater can handle more than one modem, so Modem must always be set to 0.
