Do not perform any procedure preceded by a "Caution" until described conditions are fully understood and met. Safety to Equipment When installing, replacing or using this product, observe all safety precautions during handling and operation. Failure to comply with the safety precautions and with specific precautions described elsewhere in this manual violates the safety standards of the design, manufacture, and intended use of this product. Axell Wireless assumes no liability for the customer's failure to comply with these precautions. This entire manual should be read and understood before operating or maintaining the OMU System. Class 3B Laser This product is equipped with class 3B lasers, as per definition in EN 60825-1. Caution!!! Un-terminated optical receptacles may emit laser radiation. Do not stare into beam or view with optical instruments. Optical transmitters in the opto-module can emit high energy invisible laser radiation. There is a risk for permanent damage to the eye. Always use protective cover on all cables and connectors which are not connected. Never look straight into a fibre cable or a connector. Consider that a fibre can carry transmission in both directions. During handling of laser cables or connections ensure that the source is switched off. Regard all open connectors with respect and direct them in a safe direction and never towards a reflecting surface. Reflected laser radiation should be regarded as equally hazardous as direct radiation.
AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd V Radiation Hazard This equipment emits radio frequency radiation and can, if used the wrong way, be hazardous for personnel. Here follows an example of the power densities from an intentional radiator. For radiation from a general antenna, the power density (S) at some distance is according to the well-known formula: For the repeaters described in this handbook the maximum output powers are 5 W for 900 / 1800 MHz and 10 W 2100 MHz. The corresponding power densities using a + 10 dBi antenna as an example at 1 m will be 4 W/ m² for the 900/1800 MHz output and 8 W/ m² for 2100 MHZ output. 1 m distance from the antenna at these frequencies is used as a minimum distance for practical exposure of the public. It is also difficult to have a developed EMF at distances closer than 1 m. According to R&TTE Health requirements referring to the 1999 Council recommendation, the reference level for the frequency range of 400 – 2000 MHz is f/ 200 W/ m² ( f in MHz ) and above 2 GHz, 10 W/ m². For the repeaters in this manual the levels are: GSM 900 (960 MHz) = 4.8 W/m² DC 1800 (1880 MHz) = 9.4 W/m² UMTS 2100 (2170 MHz) = 10 W/m². This means that an installation with a +10 dBi antenna does not exceed the basic restriction levels according to the recommendations. For frequencies between 400 and 2000 MHz the ICNIRP occupational guideline level of exposure is f /40 W/m² (f in MHz), and 50 W/m² for frequencies above 2 GHz. The ICNIRP levels for the frequency above bands: GSM 900 (960 MHz) = 24 W/m² DC 1800 (1880 MHz) = 47 W/m² UMTS 2100 (2170 MHz) = 50 W/m². There are no radiation health issues with the above + 10 dBi antenna installations. However, the repeater is marked with radiation hazard warning.

AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 1 11 IInnttrroodduuccttiioonn Axell MBF (Multi Band Fibre) family of repeaters comprises of three types of fibre fed repeaters: single-band, dual-band and tri-band. The repeaters are available in various models supporting frequency bands LTE 700, 850, 900, 1800, 1900, 2200 and AWS. The MBF repeater RF signal is supplied via an optic fibre connection to the Axell Optical Master Unit (OMU). The OMU is located at the Base Station RF signal source and converts the RF signal to an optical signal for routing to Repeaters via a fibre optic connection. Each OMU can support up to six repeaters.(The OMU is described in detail in the OMU User Manual).

AXELL MBF MULI-BAND FIBER REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 3 11..44 AALLCC The repeater has a constant gain in both uplink and downlink paths. The gain is set by defining the attenuation as described above. The repeater has a defined maximum output level. If the input signal amplified by the gain set exceeds the set output limit, an ALC (Automatic Level Control) loop is activated. This ALC ensures that the amplifier does not add distortion to the radio signal. Below are examples of the ALC function for one and two carriers. 11..55 OOppeerraattiinngg TTeemmppeerraattuurree Note! The MBF repeaters are designed primarily for multi carrier purposes. If the repeaters are run at full output power over a longer period the convection cooling might not be enough. The repeaters have a power management function implemented that will step down the power and if needed fully shut down the amplifier chains until temperature has reached normal values. In situations where a repeater will be run in such a manner extra cooling can be provided for instance by putting the repeater in a temperature controlled environment or via external fans. 11..66 MMBBFF IInntteerrffaacceess The MBF unit provide three types of interfaces: • Securing interfaces – lock and screws for security • Panel connections to RF, communication and power • Internal connections for local setup and for connecting optic fibres and power connections that are routed in from the ALC one carrierInput signal, dBmOutput power, dBm+36,5+33,8-24 -16Gain: 60 dB+35ALC two carriers

Connect the lightning protection The lightning hazard to electric and electronic equipment consists in the interferences of direct lightning current infections and high surge voltages induced by the electromagnetic field of nearby lightning channels or down conductors. Amplitudes from cloud-to-earth lightning amounts to several 10kA and may last longer than 2 ms. The damage caused depends on the energy involved and on the sensitivity of the electronics systems. Ensure that lightning protection measures are taken to create a reliable repeater site. Protect all coaxial cables and power cables from the transients caused by lightning. Fit all cables with suitable lightning protection devices. Example of EMV protection for a repeater system For detailed information please refer to IEC 61024-1 and 61312-1 for international standards for protection of information systems against LEMP, Lightning Electromagnetic Pulse, including radio transmitters. They define proper planning, installation and inspection of effective lightning protection systems. The Axell Wireless repeaters comply with the EN standard ETS 301 498-8 which stipulates demands on lightning/surge protection for typical infrastructure telecom equipment installations. Several lightning protection devices should be used in series with declining threshold voltages to help attenuate the pulse component which makes it through the first layer of protection.

Place the fibre in the rubber seal 5. Adjust the fibre length inside the repeater and insert the seal into the inlet 6. Attach the hose to the inlet Note! Make sure the fibre is not bent too sharply inside the repeater. There is room under the optic module to allow for some slack of the fibre. Note! To insert and extract the hose from the inlet press the side levers. Make necessary measurements Make necessary measurements to ensure a correct installation. When the cable has been installed, the quality of the optical path should be checked for optical path loss and magnitude and location of any reflections. This can be done with an Optical Time Domain Reflectometer (OTDR). The total return loss should be > 45 dB. Optical reflections can degrade the noise and linearity of a fibre optic link. In particular, reflections that reach the laser can be a problem. Keep all discrete reflections to > 60 dB. The SC/APC connectors are polished to a return loss >60 dB.
AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 12 © Axell Wireless Ltd Attach the fibre to the fibre optic converter inside the repeater. Note! Clean the fibre connector before it is connected, see instruction below. 2.5.1 Cleaning Optical Connectors Optical reflections from a discontinuity such as a poor connector interface appear on an RF spectrum analyzer trace as stable variations in the noise floor amplitude that are periodic with RF frequency. If the reflection is bad enough, it could impact the system performance. By far, the most common cause for a large discrete reflection is a dirty optical connector. A bit of dust or oil from a finger can easily interfere with, or block this light. Fortunately, it is very easy to clean the connector. Be sure to use the correct procedure for the given connector. When disconnected, cap the FC/APC connector to keep it clean and prevent scratching the tip of the ferrule. Alternative 1 Swipe the tip of the ferule 2-3 times with a cotton swab soaked in alcohol. Let it air dry. Alternative 2 Use a product specially designed for the purpose.

Dual band repeater for E-GSM and UMTS 33..22 OOMMUU PPooiinntt ooff IInntteerrffaaccee ((PPOOII)) The OMU will usually be fed from the donor BTS via an attenuator or coupling network. The electrical configuration of this OMU Point of Interface (POI) will be system specific depending on the presentation of the BTS RF ports, the power class of the BTS and whether the BTS itself provides coverage via antennas/radiating cable infrastructure or if coverage is only via the MBF repeaters. The important consideration for commissioning is that the correct attenuation exists between BTS and OMU in order that  input power limits of OMU ports are not exceeded  operating levels can be brought into the correct range using the OMU internal attenuators  isolation is preserved between ports and bands OMU damage levels are 10dBm RF in to the fibre optic converter. For some systems the commissioning adjustments may be completely independent (e.g. an MBF Tri Band repeater fed by separate OMUs, one per frequency band). For other systems (e.g. an MBF Tri Band repeater fed a by a single OMU carrying all three bands) one adjustment may affect all bands simultaneously. In such cases certain commissioning actions e.g. optical link adjustment only need to be carried out once for all bands but the POI must include some means to level the different frequency bands at the OMU interface ports. 33..33 DDoowwnnlliinnkk PPOOII // OOMMUU DDLL AAtttteennuuaattoorr AAddjjuussttmmeenntt The critical aspect for the correct system operating level is the composite power presented at the input of the fibre optic converter in the OMU (UFO-M). The illustration below shows the simplest possible arrangement for a single Tri Band repeater fed by three BTSs - one per band. It is assumed that the BTS for GSM900 and GSM1800 produce two carriers each of +43dBm and that the UMTS BTS produces a single carrier of +43dBm.

AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 22 © Axell Wireless Ltd It must also be kept in mind that the OMU might have separated input/output ports for each band (UL/DL) while the interface with the BTS may well be duplex. In that case some duplexing network must be provided to allow these to be brought together. If there is more than one operator’s BTS per band the loss of any combining network and any equipment room cabling also becomes part of the overall attenuation required to reach the correct interface level in each frequency band. The illustration on the next page shows a more complicated arrangement where the same three BTSs feed multiple MBF repeaters (up to 6 is possible using the standard splitter card which fits the OMU rack). In this case an OMU per frequency band is shown. The internal splitter has an insertion loss of 14 or 16dB depending on frequency band. This loss is again a contribution to the overall attenuation which must be provided between BTS and the input ports of the UFO-M for the correct operational levels to be achieved. The interface levels must be modified to maintain the same composite power if a greater number of carriers is to be applied from the BTS. The DL POI / OMU Adjustment must be made considering the fully loaded condition – e.g. a BTS capacity of 8 carriers must include a back off of 6dB compared to the 2 carrier level and -11dBm/carrier is then the correct UFO-M drive level for GSM 900. The same rule for back off applies in other bands. Note that a UMTS BTS at idle (no traffic) will be radiating only a pilot – approx -10dB compared to the average power when it is in traffic. See also section about UMTS Signal Measurement below. 33..44 RReeppeeaatteerr DDoowwnnlliinnkk OOppttiiccaall LLiinnkk AAddjjuussttmmeenntt ((OOLLAA)) The optical link between the UFO-M of the OMU and the UFO-S in the repeater is equipped with a calibrated pilot tone transmitter/receiver which enables compensation for the loss of the optical fibre plant between them. The OLA procedure requires a computer running Axell RMC software and an RS232 connection to the LMT Port of the repeater controller. Start the RMC and login to the repeater as described in the appropriate section of the handbook. Click on the Actions tab on top of the RMC screen. A drop down list will appear where a command will be found to execute the optical link adjustment for each UFO-S module that is fitted to the repeater. Click the command for the desired optical link and following a short delay (2-3 secs) an information screen will be shown describing the result of the automatic setup process. This procedure is described in the OMU Manual section 4.10. 33..55 DDoowwnnlliinnkk RReeppeeaatteerr GGaaiinn AAddjjuussttmmeenntt When the DL POI levels and the repeater optical links have both been set up as described in the foregoing the MBF repeater set at maximum gain should produce a composite signal level at the output connector of +37dBm for GSM900 and 1800 and +39dBm for UMTS. The RMC provides sub screens for each band where the downlink power from UFO-S optical receiver /input to the DL radio board and the composite output power level from the MCPA can be viewed. The power amplifier for each frequency band can be enabled /disabled and the preset DL attenuation in the radio board for each band can be adjusted. A saturation status indicator (red/green) shows whether the radio board ALC is in operation. This indicator should be green. A red indication indicates overdrive the cause of which should be investigated and rectified. In each band the DL output power per carrier should be measured using a spectrum analyzer. Allowing for the maximum DL carrier quantity in each band the composite level per band under full loading should be calculated to ensure it does not exceed the rated maximum otherwise ALC will be in operation when traffic levels are high.

AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 24 © Axell Wireless Ltd 33..66 UUMMTTSS SSiiggnnaall MMeeaassuurreemmeenntt The UMTS signal carries wideband and complex modulation and its properties vary depending on the level of traffic carried. 3.6.1 Bandwidth The first issue is the wideband nature of the signal. It occupies around 3.8MHz and measurements through a narrower filter will reduce the apparent power level since only a portion of the signal reaches the detector in the test equipment. Equipment that includes a UMTS/3G measurement personality simplifies the task considerably. Usually a stored configuration for power measurement will integrate many samples taken using a narrower filter to display the correct power level for the bandwidth of the signal. Settings can easily become corrupted however leading to erroneous results. In such cases following the manufacturers instructions in detail is advised. Measuring with a simple spectrum analyzer must use a wider resolution bandwidth than 3.8MHz or else a bandwidth correction factor has to be applied to the observed result. E.g. if measuring with a 300kHz RBW the power level in the centre of the signal would appear to be around 11dB lower than actual (10Log 3.84/0.3). 3.6.2 Traffic A further complication is that the power level of a UMTS signal depends on the traffic level being carried. UMTS carrier power is usually quoted as average values e.g. a 5Watt or 37dBm signal can contain peaks up to 10dB greater when traffic is high. An idling base station carrying no traffic radiates only a Pilot in which case the power observed is around 10dB below the average value with traffic. Advanced test equipment that can measure the different code power components in the UMTS signal avoids this problem but more often in the field repeater commissioning must be done when only simple test equipment is available. This leads to the need to know and allow for the state of traffic when making repeater setup and diagnostic measurements. It is obvious that adjusting a repeater to maximum rated output power by using BTSs that are idling radiating only the pilot will lead to overloading when they are in traffic.

In this example +33 dBm. Zero attenuation is the same as maximum gain. Note! Please also consult the OMU User’s Manual. Initiate a fibre loss elimination This is done from the OMU by sending a pilot tone to the repeater and calculating the loss in the fibre link. This loss is compensated for automatically. The system will behave as if there is no loss at all in the fibre link. Configure the uplink In the uplink direction the attenuation needs to be set based on a measurement of a known signal which is transmitted through the repeater and the OMU as well as the fibre. There are two ways of performing this measurement. Alternative 1 Use a signal generator to insert a signal of approximately -70dBm into the repeater’s server antenna port. Measure the signal level on the BTS or on the coupler and adjust the attenuation so that the total gain in the uplink is close to 0dB. (At 0dB gain the signal level at the coupler should be -40dBm and on the BTS -70dBm in this example.) Alternative 2 Use a signal generator to insert a signal of approximately -70dBm into the repeater’s server antenna port. Log into the OMU and monitor the uplink via the RMC. This measurement is not as accurate as alternative 1. Note! If several repeaters are connected to the same OMU the total gain in each chain should be slightly lower than 0dB not to insert too much noise into the BTS. Note!

If this interval is set to 0, the fallback will not be performed. A user can always force the Control Module to fall back to the primary address. Note! When the repeater is integrated to the Axell Element Manager system, these addresses are set by the AEM, why they need not be configured during site installation. 44..77 IInntteeggrraattiioonn iinnttoo tthhee AAEEMM When the repeater has been installed at site and the remote communication has been enabled, the repeater can be integrated to the Axell Element Manager. This is done by the operator of the AEM. After entering the telephone number to the repeater, the AEM dials up the repeater, downloads all the repeater parameters and statuses into a database. When all parameters have been downloaded, the AEM configures the repeater with the telephone number where alarms and reports should be sent, and optionally with a secondary telephone number where the repeater can dial in case connection to primary number fails. When heartbeat reports and alarms are sent from the repeater to the AEM also the latest information about the status and RF-configuration is included. This means that the AEM operator always has information about the current status in the AEM database (and do not need to call the repeater to find this out). Note! Once the repeater is integrated to the AEM, all changes to the repeater should preferably be done from the Axell Element Manager in order to ensure that the database always contains correct information.

AXELL MBF MULI-BAND FIBER REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 37 77 MMooddeemm CCoommmmuunniiccaattiioonn Note! This section is relevant only for Repeaters installed in stand-alone mode. If the repeater is fibre fed and is set up as a slave- this section is not relevant since the remote communication is handled by the node master – in most cases an OMU. The Control Module is responsible for enabling the power to the modem, unlocking the SIM-card, using the configured PIN-code and making sure the modem is logged in to the network correctly. Depending on network configuration and modem usage, the modem might require different modem initialization strings to work properly. This modem initialization string is set and verified during repeater setup. 77..11 MMooddeemm IInniittiiaalliizzaattiioonn After a power failure, or upon user request, the Control Module performs a full initialization of the modem. This consists of three steps:  If the SIM-card in the modem has the PIN code enabled, the Control Module unlocks the PIN code. In case wrong PIN-code is configured, the Control Module will not try to unlock the SIM again until the PIN-code is changed. This avoids the SIM card being locked by a Control Module repeatedly trying to unlock the SIM with the wrong PIN code.  Once the SIM is unlocked, the Control Module waits for the SIM to log in to the network. Depending on signal quality and network configuration this might take a while. The Control Module will wait a configurable number of seconds (default 50 seconds) for the modem to login to the network. In case no network is found, a modem power cycle will be initiated. When the modem is successfully logged in to the network, the Control Module configures the modem with the modem initialization string as configured when setting up the remote configuration. The modem initialization string is a network dependent string. The default string is suitable for most networks, but some networks might require some tweaking of this string. 77..22 MMoonniittoorriinngg MMooddeemm CCoonnnneeccttiioonn The Control Module constantly monitors the status of the modem connection to ensure that it is working properly, and that the modem is logged in to the network. In case the modem is not registered to the network, or the Control Module cannot properly communicate with the modem, a power cycling of the modem is initiated, after which the modem will reinitialized. 77..33 SScchheedduulleedd MMooddeemm PPoowweerr CCyycclliinngg In addition to polling the modem to ensure the repeater online status, the Control Module can be configured to perform an automatic power cycling on a scheduled time of the day. Power cycling the modem ensures the latest network configuration for the modem, such as the HLR Update Interval etc. Note! By default, the scheduled modem power cycling is disabled.
AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 38 © Axell Wireless Ltd 77..44 CCoommmmuunniiccaattiioonn vviiaa WWiirreelleessss MMooddeemm There are two different ways of communication for a wireless (GSM) modem:  Using data call / modem connection. Note! This requires the SIM-card in the modem to be configured with data service.  Using SMS to configure the repeater with simple text messages Note! SMS functionality is not implemented in this SW release. The Axell Element Manager always uses data call communication with the repeater, why all repeaters being controlled by the AEM must have data service enabled on the SIM card. Configuring the repeater to send alarms and reports via SMS it is still possible to establish data calls to the repeater, as long as the SIM card is data service enabled. 7.4.1 Modem Configuration, not using GPRS Select “Configuration” and “Communication” Select Data Call Initialization string Connect times AEM addressed are set via the AEM Select Data Call Set the modem initialization string.

These differ depending on access type: 576 for GSM, 1476 for EDGE and 1500 for WCDMA. Click on Close, and then on “Yes”. Wait for the modem to restart. This can take a few minutes. When the modem settings are ready the LED turn green. 7.4.2.1 Modem Verification When the remote configuration has been set up the communication can be verified using the modem feature of the RMC and dialling the data number. The remote communication is verified as soon as a successful remote login to the repeater has been performed. However, as a first step, it is recommended to verify that the modem is initialized correctly. After configuring the modem using the RMC, make sure to initiate a power cycling of the modem. This is done from the RMC menu. Click on the drop-down menu Actions, choose Power Cycle Modem on Logout An immediate power cycling is initiated after which the modem is initialized and registered onto the network. The modem is now ready for remote access. Ensure a successful configuration by observing the modem LED as described below. Note! This LED behaviour is valid only for GSM modems. Other modem types will be added in later editions. Green LED – Modem Status On Depending on type of call: Voice call: Connected to remote party Data call: Connected to remote party or exchange of parameters while setting up or disconnecting a call

Note! It is very important to dial the data number of the SIM. In case the voice number is dialled, the call is answered, but almost immediately the call will be hung up. 7.4.2.2 SIM-card Using Single Numbering Scheme If the network is configured using Single Numbering Scheme (SNS), some special considerations apply. The repeaters are by default configured so that networks using SNS always will have calls routed to the data service in the modem. When dialling from within the network to a repeater having an SNS-configured SIM will operate normally, since the call originator informs the system that the bearer is of type DATA. However, when dialling from outside the network trying to connect to the repeater can be difficult. Depending on the interface to the roaming network or to the PSTN network if an analogue modem is used, the bearer type can default to voice. If the bearer is set to voice, the data service cannot be converted to DATA, and a call setup cannot be completed. Note! This is not a repeater related problem; the solution is to verify how the external network interfaces handles the VOICE vs. DATA bearer type. 7.4.3 Configuration via PSTN (Fixed) Modem Also for PSTN modems data call shall be used.

Since many networks have their own “personality”, performing first time configuration of the remote communication sometimes requires tweaking of the modem parameters. This section describes some trouble shooting techniques if configuring the repeater for remote access fails. The illustration below is a simplified schematic of the remote communication between a GSM modem in a repeater and an analogue modem. The analogue modem in the computer communicates with the Interworking Function Unit (IFU), which is the GSM network analogue network interface. The call is routed via the switch centre over the air interface to the data call number in the SIM-card of the GSM module. The Control Module is responsible for establishing connections with the Axell Element Manager, and to answer incoming calls to the repeater. As described in previous sections, the Control Module only accepts one login at a time, either via Local Maintenance port (LMT) or modem connection. Hence, when verifying the remote access of the repeater, it is important to log out from the repeater locally before trying to access the repeater remotely. 2004-01-01ATE0S0=0
AXELL MBF MULI-BAND FIBER REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 43 7.5.1 Direct Modem Access To allow for advanced trouble shooting of the communications, it is possible to access the modem directly via the Control Module from a laptop computer. Log in to the repeater, either with RMC, or with a terminal emulation program, such as HyperTerminal™. When the login is completed, select Terminal Mode, this will give access to the repeater command prompt in the same way as with HyperTerminal. When the repeater prompt is accessible, type in the command ACCESS MODEM <Enter>. When typing ACCESS MODEM, the controller will send all the characters that are typed directly out to the modem port. All characters replied back from the modem will go directly to the LMT port and back to the computer. To abort an ACCESS MODEM session, press three ‘-‘ in a row (all three within one second) to come back to the repeater command prompt. Note! When accessing the modem port the modem might be configured with “echo off”, meaning that the characters entered will not be echoed back to the screen. In order to enable “echo”, press Enter. Type ATE1 <enter> (invisible) The modem replies with OK indicating that the echo is enabled. All characters entered will now be echoed back to the terminal program. 7.5.2 Trace Modem For troubleshooting purposes it is possible to trace the actual progress of initializing the modem. This trace is useful when having problems with the modem initialization.

AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 44 © Axell Wireless Ltd To end session type CTRL-Z 7.5.3 Manually Answering Incoming Calls It is possible to manually answer incoming calls without involving the repeater software at all, to verify that the remote access and the network itself works as intended. In order to verify the remote communication, make sure to have someone stand by to dial up the repeater with a terminal emulation program, for example HyperTerminal™. Go in to Direct Modem Access as described earlier. When in direct access mode, ask the person standing by to dial up the repeater. As soon as a call is received, the text RING will repeatedly be displayed on the screen. Type ATA <enter> This will inform the modem to answer (ATtention Answer). When the connection is established, a connect message will be displayed including the connection speed. Sometimes the information comes together with some miscellaneous information, such as error correction protocols etc. Note! Make sure the remote peer dials the Data Call number If the voice number is dialled instead of the data number, or if the modem contains an illegal modem initialization string, the message OK or NO CARRIER will be displayed almost immediately. Try to change the modem initialization string. The modem initialization string mainly used to configure the remote communication is AT+CBST. Successful modem initialization strings used by Axell Wireless includes (most common first): AT+CBST=71,0,1;\Q3 AT+CBST=7,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=7,0,3;\Q3 Once the modem initialization string is entered, try again to dial up the repeater. For details on the different modem initialization strings, please refer to the modem’s user guide. If the setup is successful, the connect message will be brought up;
AXELL MBF MULI-BAND FIBER REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 45 CONNECT 9600 This means that an online connection is established to the remote peer. From now on, all characters typed on the keyboard will end up on the remote peer’s screen. Similarly, all characters typed by the remote peer will be displayed on the screen. In the example, the incoming call was successfully answered, and the remote user entered the text message. In order to come back to modem command mode, press +++ (three pluses) rapidly (within one second). Receiving OK means that the modem is back in command mode. Type ATH <enter> This terminates the connection to the remote peer. The message NO CARRIER will be displayed. 7.5.4 Common Problems 7.5.4.1 Problem 1 When enabling the remote access for the repeater, the modem fails to log in to the network. 7.5.4.2 Solution Signal strength from the donor site is too low. The signal strength can be read directly from the modem. Go in to Direct Modem Access as described earlier. Use the command AT+CSQ (documented below) to read out the signal strength. In order to have good signal quality, Axell Wireless recommends that the signal strength should be better than -95 dBm. If signal strength is lower, try to adjust the antennas to get a better signal strength from the donor.
AXELL MBF MULI-BAND FIBRE REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL 46 © Axell Wireless Ltd Documentation of +CSQ command from a modem’s manual. In the example the reply to AT+CSQ is 0,7 meaning 7*2 dB above -113 dBm; the modem detects a signal level of -99 dBm. 7.5.4.3 Problem 2a Repeater is configured properly, and answers the incoming call, but when trying to dial the repeater using an analogue mode, no modem handshaking is heard from the dialling modem. 7.5.4.4 Problem 2b When dialling the repeater, the repeater answers the incoming call, but no connection is established, and after a while the repeater disconnects the call. 7.5.4.5 Solution The most common cause is that the number called is the voice number of the SIM, not the data number. Therefore, make sure to dial the data number. If data call is used, the problem probably is an illegal modem initialization string. In order to change the modem string, go to the repeater command prompt. Try changing the modem initialization string and log out to let the controller reinitialize the modem.
AXELL MBF MULI-BAND FIBER REPEATER PRODUCT DESCRIPTION AND USER’S MANUAL © Axell Wireless Ltd 47 If problem remains, try a few different modem initialization strings. Axell Wireless has been successful with the following modem initialization strings: AT+CBST=71,0,1;\Q3 AT+CBST=7,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=0,0,1;\Q3 AT+CBST=7,0,3;\Q3 Please refer to the modem manual for detailed description of the modem initialization strings. 7.5.4.6 Problem 3 It is possible to call the repeater from another GSM mobile, but not from an analogue modem. 7.5.4.7 Solution This problem is most likely related to the modem configuration and/or the configuration of the IFU unit. Try to decrease the communications speed and make sure that the modem error correction is supported by the IFU. Verify the IFU configuration to see if there are any known problems with the modem connections. 7.5.4.8 Problem 4 When dialling the repeater, or when the repeater is dialling the Element Manager, the connection is terminated before the handshaking is completed. 7.5.4.9 Solution When a repeater is answering an incoming modem call, or calling up the OMC to deliver an alarm or a report, the repeater will wait a configurable number of seconds for the call to be established. If no communication is established within this time, the call will be hung up. If this interval is set too low, the handshaking is terminated too fast. In the RMC, verify the Modem Connect Time to see that it is set to at least 30 seconds.
