1.5. Compliance with ISED
WARNING: This is NOT a CONSUMER device. It is designed for installation by an installer approved by an ISED licensee. You MUST have an ISED LICENCE or the express consent of an ISED licensee to operate this device.
Under Innovation, Science and Economic Development (ISED) Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication.
The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. This equipment complies with ISED RSS-102 radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance of 2.15 m between the antenna and your body,
The installation procedure must result in the signal booster complying with ISED requirements RSS­131 Clause 6.3 and 6.4. In order to meet ISED requirements RSS-131 Clause 6.3 and 6.4, it may be necessary for the installer to reduce the UL and/or DL output power for certain installations.
Conformément à la réglementation d'Innovation, Sciences et Développement Économique (ISDE) Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec porteuse unique. Pour des appareils avec porteuses multiples, on doit réduire la valeur nominale de 3.5dB, surtout si le signal de sortie est retransmis et qu'il peut causer du brouillage aux utilisateurs de bandes adjacentes. Une telle réduction doit porter sur la puissance d'entrée ou sur le gain, et ne doit pas se faire au moyen d'un atténuateur raccordé à la sortie du dispositif. Cet appareil est conforme aux limitations de la norme ISDE RSS-102 concernant l’exposition aux radiations dans un environnement non contrôlé. Cet appareil doit être installé et utilisé avec une distance minimale de 2.15 m entre l’antenne et le corps de l’utilisateur.
La procédure d'installation doit permettre à l'amplificateur de signal de se conformer aux exigences ISDE RSS-131 Clause 6.3 et 6.4. Afin de respecter les exigences de la norme ISDE RSS-131, paragraphes 6.3 et 6.4, il peut être nécessaire que l'installateur réduise la puissance de sortie UL et / ou DL pour certaines installations.

1.6.4. Antenna Installation
Installation of an antenna must comply with the FCC RF exposure requirements. The antenna used for this transmitter must be mounted on permanent structures.
The FCC regulations mandate that the ERP of type B signal boosters should not exceed 5W, this is equivalent to 8.2W EIRP.
Therefore the max antenna gain allowed for this type of signal booster should be limited to the values given by equation 1 (below) for the service antenna.
Equation (1) - Max SERVICE antenna gain
Max SERVICE antenna gain (dBi) = 39.1 – (37dBm - # of antennas in dB – cable losses in dB).
For example:
No. of Antennas
Cable Losses
Max Allowed Antenna Gain

39.1- (37-0-3) = 5.1dbi
10

39.1- (37-10-3) = 15.1dbi
1.6.5. Compliance with FCC deployment rule regarding the radiation of noise
Good engineering practice must be used in regard to the signal booster’s noise radiation. Thus, the
gain of the signal booster should be set so that the ERP of the output noise from the signal booster should not exceed the level of -43 dBm in 10 kHz measurement bandwidth.
In the event that the noise level measured exceeds the aforementioned value, the signal booster gain should be decreased accordingly.
In general, the ERP of noise on a spectrum more than 1 MHz outside of the pass band should not exceed -70 dBm in a 10 kHz measurement bandwidth.
The BSF0060 Repeater has a noise level of -66 dBm in 10 kHz measurement at 1 MHz spectrum outside the passband of the signal booster and an in-band noise level at around -46 dBm in a 10 kHz bandwidth. Therefore, the noise at the antenna input port should be calculated based on equation (2).
Equation (2) - Input Noise to service antenna
Input Noise to service antenna:
-66 dBm – Antenna splitter losses in dB – cable loss in dB

Example: In band Noise
Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12dB
Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (2) Input antenna noise (to the antenna) = -46-12 -11=-69 dBm ERP The in-band input noise to the antenna should be -46 -12-11= -69dbm ERP
Example: Out of band noise
Signal booster connected to 10 service antennas with a 100m long ½ inch cable. Losses of such a cable with the connectors = ~ 12dB
Assuming 10 service antennas: antenna splitter losses = 11 dB Based on equation (2) Input antenna noise (to the antenna) = -66 -12 -11=-89dBm ERP The Out of-band input noise to the antenna should be -66 -12-11= -89dbm ERP
NOTE: In this example there is no need to add an external band pass filter to attenuate the out of
band noise. If fewer antennas are deployed then additional filtering may be required
Conclusion:
Good engineering practice requires that in general when the out of band noise measured at the service antenna input is more than -70 dBm per 10 kHz measurement bandwidth, an external band pass filter should be added to attenuate the out of band noise level.
All Cobham Wireless repeaters include high selectivity duplexers and filters to attenuate the out of band noise. Should additional filtering be required, we have a comprehensive range of interference filters which can be supplied upon request.

2. Safety Notices
2.1. Earthing of Equipment
Equipment supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations.
2.2. Electric Shock Hazard
The risk of electrical shocks due to faulty mains driven power supplies whilst potentially ever present in any electrical equipment, would be minimised by adherence to good installation practice and thorough testing at the following stages: a) Original assembly. b) Commissioning. c) Regular intervals, thereafter.
All test equipment must be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection.
2.3. RF Radiation Hazard
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to Cobham Wireless equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a
‘spare’ output has been left un-terminated. Either of these conditions would impair the
system’s efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would severely
compromise the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched!
Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.
2.4. Lifting and other Health and Safety Recommendations
Certain items of Cobham Wireless equipment are heavy and care should be taken when lifting them by hand. Ensure that a suitable number of personnel, appropriate lifting apparatus and appropriate personal protective equipment is used especially when installing Equipment above ground e.g. on a mast or pole and manual handling precautions relevant to items of the weight of the equipment being worked on must
be observed at all times when handling, installing or dismounting this equipment.

2.5. Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes
used in devices within equipment produced by Cobham Wireless. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact.
Products that contain beryllium are load terminations (dummy loads) and some power amplifiers. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above). They are marked as hazardous in line with international regulations, but pose no threat under normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created will be contained within the equipment module as long as the module remains sealed. For this reason, any module carrying the yellow and black danger sign should not be opened. If the equipment is suspected of failure, or is at the end of its life-cycle, it must be returned to Cobham Wireless Ltd. for disposal.
To return such equipment, please contact the Support Desk, who will give you a Returned Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on all correspondence relating to the shipment.
Polytetrafluoroethylene, (P.T.F.E.) and P.T.F.E. Composite Materials Many modules/components in Cobham Wireless equipment contain P.T.F.E. as part of the RF insulation barrier. This material should never be heated to the point where smoke or fumes are evolved. Any person feeling drowsy after coming into contact with P.T.F.E., especially dust or fumes should seek medical attention.
2.6. Laser Safety
General good working practices adapted from EN60825-2: 2004/ EC 60825-2:2004
Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or connector faces or point them at other people, Use only approved filtered or
attenuating viewing aids. Any single or multiple fibre end or ends found not to be terminated (for example, matched, spliced) shall be individually or collectively covered when not being worked on. They shall not be readily visible and sharp ends shall not be exposed. When using test cords, the optical power source shall be the last connected and the first disconnected; use only approved methods for cleaning and preparing optical fibres and optical connectors. Always keep optical connectors covered to avoid physical damage and do not allow any dirt/foreign material ingress on the optical connector bulkheads. The optical fibre jumper cable minimum bend radius is 3cm; bending to a smaller radius may result in optical cable breakage and excessive transmission losses. Caution: The FO units are NOT weather proof.
2.7. Emergency Contact Numbers
The Cobham Wireless Support Desk can be contacted on: Telephone +44 (0)1494 777747 Fax. +44 (0)1494 777002 e-mail cw.support@cobham.com

3. BSF3604-406-411-115VAC - BSF0060
BSF3604-406-411-115VAC part number BSF0060 is a band-selective, Class B, fibre-fed repeater built in to a dual purpose rack or wall-mounting, environmentally protected (IP65) aluminium alloy case; external ports and connectors are also IP65 standard making the entire enclosure and connecting ports weatherproof. Handles are provided for carrying the unit and the door is fitted with locks.
BSF0060 houses a fibre optic transceiver module for demodulating the Downlink optical signals to RF and modulating the Uplink RF signals to optical to be transmitted to the Master Site. BSF0060 also houses a Digital Signal Processing (DSP) module and a Downlink power amplifier to amplify channels in the bands 406-420 MHz. It is designed for FM and P25 modulations with the emission designators F1E and F3E.
The repeater houses a bandpass duplexer module connected to a common TX output/RX input port (the “Server” port) for single antenna operation. The bandpass filters in the Duplexer module are used to limit the out of band noise and prevent out-of-band signals from overloading the DSP Module.
Downlink. BSF0060 receives a F/O feed via a WDM optical cable link from the master site. The F/O feed passes into a F/O transceiver module and is demodulated to RF.
The RF Downlink path then passes through a 30dB coaxial attenuator and into the Downlink path of the Digital Signal Processing Module which utilises SDR technology to digitally process the signals to define the required channel frequency and bandwidth; automatic gain control and signal attenuation functions are also provided.
The Downlink path then passes through a Multi-Carrier Power Amplifier; and then enters the Downlink path of the Bandpass Duplexer module which filters the signal to pass the required Downlink passband and reject out-of-band noise and then combines the Downlink and Uplink paths whilst providing isolation between the two paths. The Downlink signal then exits BSF0060 via the common TX/RX “Server” port.
Uplink. The Uplink signal from the enters BSF0060 via the common TX/RX “Server” port and passes into the Uplink path of the Bandpass Duplexer module which splits the Uplink from the Downlink path, filters the signal to pass the required Uplink passband and reject out-of-band noise whilst providing isolation between the Uplink and Downlink paths.
The Uplink signal then enters the Uplink path of the Digital Signal Processing Module which utilises SDR technology to digitally process the signals to define the required channel frequencies and bandwidths; automatic gain control and signal attenuation functions are also provided.
The Uplink path then passes into the F/O transceiver module where the RF signal is modulated onto a laser for onward transmission to the master site as an optical signal over the WDM fibre optic cable link
BSF0060 is powered by 115V AC which drives an internal power supply unit which provides a range of DC voltages for the internal active modules. A supply On/Standby switch is fitted inside the unit.
An alarm system is fitted; active modules have alarm outputs which are collated by the Control Module and modulated onto the Uplink optical signal for interrogation at the master site. The alarm data is also made available via an Ethernet link which offers the ability of remote configuration and a summary alarm, voltage-free contact relay output is made available via terminals 11 and 12 of the external interface terminal block located in the base of the repeater.

3.1. Automatic Level Control
BSF0060 is equipped with Automatic Level Control (ALC). The ALC feature enables maintaining the maximum defined output level.
The repeater has a defined maximum output level. If the input signal amplified by the gain set exceeds the set output limit, an ALC 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.

3.6.1. Control Module
The Control Module is based upon a Linux processor and software, which is used to control and monitor the active components within the repeater. A Web browser accessed GUI allows the operator to enter the required channel frequencies and to adjust the Gain and Squelch settings.
The Control Module performs the following functions:
● Provides an RS232 and USB port for local connection enabling local interrogation of alarm
data by PC/laptop.
● Provides an Ethernet port for remote reporting/interrogation of alarm data by PC/laptop.
The controller also provides a summary alarm output upon the failure of any active device and has four LEDs which give information regarding the
status of the Control Module.

3.6.2. Fibre Optic Transceiver Module
The Fibre Optic Transceiver Module provides Optical to RF signal conversion in the Downlink direction and RF to Optical signal conversion in the Uplink direction. As downlink and uplink optical signals are combined using WDM, only one fibre link is required. The Fibre Optic Transceiver Module in the repeater works in parallel with a corresponding unit in an OMU at the master site which is linked via the optical fibre connection (SC/APC port). A pilot tone can be sent between the Fibre Optic Transceiver Module in the OMU and the repeater to define the loss in the fibre. Based on this information the repeater automatically adjusts the attenuation to compensate for the fibre loss.
Caution! Class 1 Laser Product. Un-terminated optical receptacles may emit laser radiation. Do not stare into the beam or view with optical instruments.
On the Fibre Optic Transceiver Module there are six LED indicators; one for power status, one for error, two for the data communication and two for the Optical signals.

3.6.3. PSU Module
The Repeater’s internal PSU Module is a high efficiency 300w switched mode device that converts the
110V AC input to a range of DC voltages (28V, 15V and 6.45V) to power the internal active modules. The PSU Module has a switch which allows it to be set in the “on” or “standby” position; setting the switch to standby will disable the repeater.
Note! In the standby position the PSU module and repeater are still connected to the AC power
supply but the PSU module is not operational. The PSU module on/standby switch is located on the top of the PSU module.
The PSU Module is fitted with a rechargeable battery pack which will provide the Control Module with enough capacity to send an alarm in the event of AC power failure. The PSU Module also includes charging and supervision electronics for the battery backup function. The battery can be switched on and off. The switch is placed adjacent to the PSU On/Standby switch on the top of the PSU module. At delivery the back-up battery is connected; the battery is replaced by lifting the battery pack out of its recess in the PSU module and disconnecting the cable.
The PSU module has four LED Status Indicators, A green LED indicates that the input power to the PSU is functioning correctly.
Three red LEDs indicate the health of the three output voltages supplied by the PSU.

3.6.5. Digital Signal Processing (DSP) module
The DSP module is a wideband RF module that digitises factory set segments of the full bandwidth, the setting of the segments of spectrum is performed at factory initialisation and is not field adjustable. Once the equipment leaves the factory its operating bandwidth is already set by the initialisation and the external duplexing filters used to separate and define the required Part 90 Tx and Rx frequency bands.
The DSP module provides the initial gain in the DL path and the entire gain in the UL direction. Internal ceramic filters provide UL and DL selectivity, in addition it provides attenuation control and level control in both the UL and DL directions, the overall repeater has a defined maximum output level, if the input signal amplified by the gain set exceeds the set output limit, an ALC loop is activated in the DSP module which has a range of 20dB. This ALC ensures that the amplifier does not add distortion to the radio signal.
3.6.6. Multi Carrier Power Amplifier (MCPA)
The Downlink output MCPA provides 37dB of gain and has a P1dB of 47dBm and an IP3 of 68dBm. The MCPA utilises high linearity class A techniques to minimise Intermodulation generation in the presence of multiple carriers. The amplifier output power is limited to 36dBm (4W) composite power to ensure high linearity to keep spurious products to a minimum.
3.6.7. Bandpass Duplexer Module
The bandpass duplexer module is connected to a common output/input port for single antenna operation. The purpose of the duplexer is to ensure that the equipment operating bandwidth is limited to the band of frequencies required to be amplified/repeated. The filters in the duplexer ensure that noise and any Intermodulation is limited to within the operating transmission band. The filters must prevent any noise reaching the antenna port at the receiver frequencies as any noise at this point will affect the ability to receive. The receiver input filter is used to ensure that only the required input band of frequencies is presented to the DSP module. The filter also ensures that the high level Downlink transmit output does not cause overload damage by blocking the receiver’s ability to detect the wanted Uplink input frequencies.
3.6.8. Reference Generator Board
The Reference Generator is used to provide an accurate stable 10 MHz Reference signal to the DSP module to ensure that the channel selectivity is centred on the wanted channel frequency.
3.6.9. Distribution Board
The Distribution board is used to connect the DC power and the RS485 control signals between the associated modules and the PSU/Control Module.

5. Repeater Installation
5.1. Location Criteria
● Wall compatibility - check the suitability of the wall on which the BSF0060 is to be to be
fitted.
● Plan mount - check the actual fixing centres (see below) and overall dimensions of the
BSF0060 enclosure. The BSF0060 is supplied with two wall mounting brackets; when the BSF0060 is mounted on these brackets adequate ventilation is provided between the BSF0060 and the wall to which it is fixed.
● Plan connection cable clearances - the Optical, RF and power connections located on the
underside of the BSF0060 will need at least 300mm vertical clearance below the BSF0060 to enable the connections to be made. The minimum bend radius for Optical and RF cables must not be less than the recommendations made by the cable manufacturer. Plan the cable runs and ensure adequate space is available.
● Allow for door opening - ensure that there is sufficient space at the front of the BSF0060 to
allow the door to be fully opened and for maintenance engineers to get access to the unit with test equipment such as a spectrum analyzer. Allow an additional 500mm of space in front of the BSF0060 when the door is fully open.
● Allow for heat dispersion - Mount the repeater so that heat can be dispersed from it.
● The repeater wall mounting kit ensures an optimum airflow between the wall and the
repeater.) Do not block this air channel as it will cause the MTBF of the repeater to drop dramatically, or even in the worst case cause the repeater to fail completely. If possible, use a wall in the shade to minimize the overall sun loading. If sufficient shielding cannot be obtained, an additional sun shield should be mounted.

5.4. Mounting the Repeater onto a Wall
WARNING! Due to the weight of the Repeater, it is NOT recommended to fix the
repeater to a hollow wall
Caution: It is recommended that when lifting, two persons handle the equipment as depending upon the configuration the Repeater weighs between 20 and 33 kg
Check the suitability of the wall on which the Repeater is to be to be fitted. At this point it is recommended that the actual fixing centres (see below) and overall dimensions of the Repeater enclosure are checked. The Repeater is supplied with two wall mounting brackets; when the Repeater is mounted on these brackets adequate ventilation is provided between the Repeater and the wall to which it is fixed.
The Optical, RF and power connections located on the underside of the Repeater will need at least 300mm vertical clearance below the Repeater to enable the connections to be made. The minimum bend radius for Optical and RF cables must not be less than the recommendations made by the cable manufacturer. Plan the cable runs and ensure adequate space is available.
Ensure that there is sufficient space at the front of the Repeater to allow the door to be fully opened and for maintenance engineers to get access to the unit with test equipment such as a spectrum analyser. Allow an additional 500mm of space in front of the Repeater when the door is fully open.
Fix M6 Rawlbolts or similar (50 to 75mm in length) into the wall at the dimensions as illustrated in figure 1 below using equipment as specified by the fixing manufacturer. A recommended method is set out below. Care must be taken to ensure the alignment of the four fixings. A spirit level or plumb line should be used to ensure horizontal/vertical alignment.

The Repeater affixed to its wall mount brackets should be fixed to a solid wall (these include brickwork, blockwork, and concrete.); due to the weight of the Repeater, fixing to a hollow wall is not recommended. Always check that there are no pipes or cables hidden in the wall beneath the area to be drilled. Various pipe and cable detectors are available to check this.
To provide secure fixing to a solid wall, the most common method is drilling and plugging. The size of fixing is dependent on the item to be fixed and the nature of the wall, The Repeater should be fixed with mild steel, M6 (x 50mm to 75mm) rawlbolts or similar.
First mark out on the chosen wall the fixing centres of the repeater (see above.).
Mark and drill the wall with the correct size masonry bit as specified by the fixing manufacturer.
It is good practice to wear goggles to protect your eyes from flying debris when using power tools.
Hold the drill bit against the mark and begin drilling slowly so that the bit does not wander from the position.
The wall should be drilled to a depth which is sufficient to accommodate the full length of the fixing.
Insert the fixings so that the top of the sleeve/anchor section is level with the wall surface, gently tighten the bolt by hand so that the anchor section of the fixing expands and grips the inside of the hole.
As the bolt pulls its way in, the sides of the anchor section are forced outwards, gripping the surrounding surface.
When all four fixings are in place, carefully withdraw the bolt sections and offer up the Repeater to the wall. Great care should be exercised here as the repeater is very heavy.
When the Repeater held in position against the wall in the chosen position (a suitably rated heavy duty scissor lift table/trolley may be suitable for this operation) carefully insert the fixing bolts through the mounting lugs of the Repeater and into the sleeve/anchor sections of the fixing in the wall and tighten the bolts.

6.2. User Access
There is one default user name and password defined for the repeater. (More than one user at a time can be logged in).
User Name
Password
avitec
AvitecPasswd
Note: Both the user name and the password are case sensitive.
The password can be changed and new accounts be added once a logon has been made. This is made in terminal mode. Please refer to the document “CSR-CSFT438 Commands and Attributes”. A user will be automatically logged out after a pre-determined period of inactivity. This time period can be defined via the RMC.
6.3. Define Repeater General Info
When the repeater is integrated into the Active Element Manager the unit is assigned a repeater ID, which is a unique identifier in the repeater network. This ID is used by the AEM to keep track of the repeaters in the AEM database.
The repeater can also be assigned a nickname (TAG) which can also be easily read by the AEM during AEM integration, providing the AEM operator a clear identification of the site.
To assign general parameters
1. In the left pane, select the Configuration window option and choose Product. The General dialog appears.
2. In the Tag field, assign the Repeater a name (up to 30 characters) that indicates the location of the Repeater. The repeater tag can be locked (enable Lock TAG option) so that the tag cannot be accidentally modified from the AEM side.
3. Set the Repeater Current Date and Current Time. These will be to timestamp events.
Note! Do not assign an ID.
The AEM will do this automatically when the repeater is integrated in the AEM.

6.4. Configuring RF Parameters
The local setup procedure consists of verifying online communication with the connected unit, defining the repeater channels and configuring attenuation levels and DL and UL chains.
To configure RF parameters
1. In the left pane, select the RF/Status window option. The RF Settings, Status and Levels pane appears.
Chain
2. Define the channels to be used:
● Select an active Chain (appears in blue).
● Open the Channel list and select a channel and click OK.

3. Set the D/L and U/L output power levels in the corresponding fields:
● The maximum power level can be set individually for uplink and downlink of each channel.
● The level can be set in 1 dBm steps from maximum power “Max” to maximum power minus
9 dBm “Max-9”.
● The Max. power level depends on the number of chains used (decreases with each
additional chain).
● The power level can also be set to OFF, meaning that no output power is transmitted out in
the chain.
Output power level
Note! Verify that the power levels for the inactive chains are set to OFF.
The current value can be read in the top part of this screen (36 dBm in example below).
Current measured power level (depends on no. of chains used)
4. In Config field, select Low Delay or High Selectivity for the U/L and D/L frequencies.
5. In the Downlink:
Verify that the Return Loss is approximately 10dB, indicating the antenna is installed
correctly. (The Return Loss measures the reflected signal on the Server Antenna port of the repeater. If the value is approximately 3dB, either the port is open or check the antenna installation.).
Set attenuation to maximum value.
Note! The values shown in the figure below are for example only.
Config field
U/L Attenuation D/L Attenuation
Lower the Attenuation level step by step until the desired output power level is reached. In
this example +30 dBm. (Zero attenuation = maximum gain).

6. In the Uplink, set the Attenuation 2dB higher than in the downlink path. Since the base station is more sensitive than a mobile unit there may be less signal gain from the mobile unit in to the base station (U/L) than in the opposite direction. The uplink attenuation can be adjusted more accurately later on, once the drive test signal measurements have been completed.
6.5. Configuring External Alarms and Relay
This section describes how to define set the external alarms to “active high” or “active low.” You can
also set the delay time (in seconds) in which a fault can be detected before an alarm is generated.
6.5.1. Configuring External Alarms
To configure the external alarms
1. In the RMC Main window, select the Configuration window option and click on Alarms. The External Alarms configuration options are located at the bottom of the screen.
External alarms
1. In the External Alarms Configuration area, set the levels of each alarm:
Active High – voltage triggers alarm Active Low – no voltage triggers alarm
2. Assign a description to each relevant alarm:
In the External Alarms Description area, click Edit.
Assign a description to each relevant alarm (up to 19 characters).

6.5.2. Configuring and Testing the Relay
This section describes how to set the relay activation and how to test the Relay function.
Note! The relay status is not affected by the login / logout alarm parameters.
For installation testing purposes, it is possible to test the open / close function of the relay. This test procedure makes sure the relay is closed for 3 seconds, then opens for 10 seconds, and finally closes for 3 seconds before going back to original state.
1. In the RMC Main window, select the Configuration window option. The Relay configuration options are located at the bottom of the screen.
2. The relay can be set to close or open to indicate an alarm. This can be changed by changing the polarity.
Click to test

6.6. TCP/IP Communication Configuration – for Remote Monitoring
A TCP/IP communication is run over a company’s network. Therefore each company needs to define
the details regarding the configuration, IP addresses, etc.
Note! For more information please refer to the document “Common Commands and Attributes”,
(available from Cobham Wireless) section 12, Network and USB Configurations.
1. Select Configuration and choose Communication. The following window appears.

2 Set the IP Address method as either Dynamic or Static.
3. Set the DNS or Gateway address.
6.7. Integration into the AEM
When the repeater has been installed at site and the remote communication has been enabled, the repeater can be integrated to the Active 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 Active Element Manager in order to ensure that the database always contains correct information.
