- 5 -Cellular Specialties, Inc. (CSI) developed the DSP digital repeater for use within enclosed structures where signal from local dispatch sitesis insufficient to operate on scene communication equipment. Adequate signal must be available outside the structure as a prerequisite toachieving in-building coverage. The Digital Repeater is connected to an external antenna, usually on the roof, and to one or more internalantennas placed strategically throughout the area where wireless service is desired.The external antenna typically is directional, such as a “yagi”. Internal antennas are typically omnidirectional, although various other typesmay be used depending on the coverage application. The CSI DSP Repeater amplifies both the “uplink” (Transceiver to tower) &“downlink”(tower to Transceiver) signals thus facilitating communications to and from the intended wireless infrastructure.With a maximum total of +85dB nominal gain on both the up and down links, gain can be adjusted over a range from +53.5dB to +85dB in0.5dB steps. Control of the repeater is achieved utilizing a computer connected to comm. port 1 or 2 or via a Crossover Ethernet cableconnected to the Ethernet port. There are also LED indicators near the display to indicate ALARM status, AGC status, UL PWR, DL PWR,OSC, SHUT DWN and a D/L SIGNAL STRENGTH bargraph.A specific filtering process modifies each amplification chain. This process digitally converts the assigned spectrum and then appliesdigital signal processing (DSP) techniques. DSP is used to create passbands that selects the RF energy passing through either the uplinkor downlink paths. After the digital processing is complete, the information is converted back to an analog signal that is applied to theremaining stages of amplification. The resulting signals emitted by the repeater are specific to the network service providers’ require-ments. If these requirements change, only the DSP configuration parameters need change in order to adapt. Configuration parameters arecreated at the factory and supplied as files that may be downloaded to the repeater. The filter set configurations stored in memorydetermine the unit’s adaptability to various field applications. The following pages describe the public safety band plan as well as theconvention CSI uses to identify and store the files that make up the filter set. All DSP85 repeaters are shipped with an active filter set thatis programmed according to the ordering parties’ specifications. In most cases, the installer will not have to program a filter.AGC= Automatic Gain Control ERP= Effective Radiated PowerAPC= Automatic Power Control FPGA= Field Programmable Gate ArrayAUI= Attachment Unit Interface LED= Light Emitting DiodeCPU= Central Processing Unit OIP3= Third-Order Intercept PointCSI= Cellular Specialties, Inc.

The outdoor antenna used for thepurpose of communicating to the wireless infrastructure is limited to 14dBi gain, or any combination of gain and loss that equates to14dB at input. Each antenna must be positioned to observe minimum separation requirements from all users and bystanders. Thefollowing guidelines should be used when considering separation distances.INDOOR antennas must be placed such that, under normal conditions, personnel cannot come within 20 cm (~8.0 in.) from any insideantenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF exposures beyond themaximum permissible limit as defined by section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.OUTDOOR antenna must be positioned such that, under normal conditions, personnel cannot approach closer than 120 cm. (~4 ft.). Adirectional antenna having a maximum gain of 14 dBi is used, precautions should be taken to prevent personnel from routinely passingthrough the main radiation beam at a distance closer than specified.Product IntroductionTerms used in this manualImportant Safety Information

-8-EIA232 Pin SpecificationsThe diagram above is for reference only, it’s intended to provide a quick source for pinoutinformation in the event it should be necessary to adapt your serial cable because of an unusualconnector configuration. In the vast majority of cases this information will not be needed.To allow monitoring and control, the repeater is equipped with four ports that provide external communication access (1 EthernetCAT-5, 2 DB-9 serial, and 1 USB). The Ethernet, CAT-5 port is provided as a primary communications port to the PC. One serialinterface provides communications to local PC and the second to an external modem when provided. The USB interface provides ameans to download files from a memory device and may also be used by an external modem. The DB-9 pin assignments conformto the standard Electronic Industries Association (EIA232) specification. A diagram of the pin descriptions is provided on this pagefor reference.Connecting a null modem cable to one of the COM ports and using a terminal emulation program with a PC will allow communicationto the control processor’s Text Menu Interface (TMI). See command line interface section for further detail.The Universal Serial Bus (USB) interface conforms to Intel’s Universal Host ControllerInterface (UHCI) version 1.1 dated March 21, 1996. This interface will support data transferrates up to 12 Mbps and can be used for software updates and filter file uploads.Local Communication Interface PortsUSB InterfaceThe Ethernet AUI conforms to IEEE 802.3 and is capable of supporting 10/100 Mbpscommunications speeds. This port is used to provide access to the GUI.Ethernet
- 9 -All cables should be checked for shorts and opens. Also verify that there are no cables with loose or poor connec-tions. RF leakage could cause oscillation to occur under some conditions.The rooftop antenna (Donor Antenna), if directional, should be checked for proper alignment along the calculatedcompass heading. Typically, the directional antenna would be aimed at the same site that your handset uses, but it maynot always be so. It is critical the installer contact the service provider for information on, and approvalof, the site he or she has selected before the system is turned on.If cables and alignment are acceptable and a problem persists, it may be necessary to use a spectrum analyzer toexamine the signal environment in which the unit is operating. The existence of strong adjacent channel signals withinthe frequency band(s) can cause the AGC to reduce the amplifier’s gain or cause alarms. In some cases additionalfiltering or attenuation might be required to reject these unwanted signals. In some instances, the donor antenna can bereoriented horizontally, to place the interference source in an antenna pattern “null”. There also may be some caseswhere the interference from outside signals is so great that they cannot be filtered or otherwise reduced or eliminatedwithout expensive and possibly prohibitive measures. In these cases it may not be practical to use the CSI repeater forproviding coverage to these sites.1:1 PORT CONFIGURATION Input: One single band duplex port, from the dual band donor.Output: One single band duplex port to the DAS.There are no physical connections provided to specifically communicate system or alarm status. This information isembedded in the information accessible via the communication ports described earlier.Monitoring & AlarmsSystem Set-Up ConsiderationsSelection of external attenuators to be used in line with the Antenna Port(s)
- 10 -If a CSI repeater is installed in an area with very strong desired and/or undesired signals, it is important to ensure that the overall signal levels areoptimized to be within the best operating range of the repeater. Additionally, de-sensing of a nearby base station site must be avoided. These goalscan be accomplished by properly attenuating the antenna port(s) in the path of the donor antenna(s). In effect, one can imagine that the particularrepeater deployment is electrically moved farther from the base station using attenuators that are equivalent to increasing the path loss from thedonor antenna to the base station. The following potential outcomes result from the use of attenuators on the donor port(s) of the unit: Uplink outputpower, as reported by the repeater, is reduced by the value of the attenuation, protecting nearby base stations. Downlink signal to noise ratio is highat the point of the attenuator, resulting in slight but negligible reduction in downlink performance. Other performance is essentially unchanged.DONOR PORTServer port attenuation may also be necessary, particularly where a powered DAS is present. The selection guidelines below apply to both serverand donor ports. In order to properly measure uplink signal strength, a signal generator should be used. If a signal generator is not available, placinga test call while under the server antenna with the least path loss to the repeater should provide reasonable data.The following potential outcomes result from the use of attenuators on the server port(s) of the CS repeater: Downlink output power, as reportedby the unit, is reduced by the value of the attenuation. Uplink incoming power from the DAS is reduced, along with potentially strong and/or harmfulout-of-band signals (including noise) that are generated by the DAS.SERVER PORTAttenuator Selection GuidelinesAccurate attenuator values need to be chosen to ensure that the maximum total power (higher of Composite or In-Band Input) applied to the donorand server port(s) does not exceed the following thresholds:Input Signal Max Gain Input Signal Max Gain <-45 dBm 85 dB -32.2 dBm 69 dB -44.3 dBm 84 dB -31.4 dBm 68 dB -43.6 dBm 83 dB -30.6 dBm 67 dB -42.9 dBm 82 dB -29.8 dBm 66 dB -42.2 dBm 81 dB -29 dBm 65 dB -41.5 dBm 80 dB -28.2 dBm 64 dB -40.6 dBm 79 dB -27.4 dBm 63 dB -39.7 dBm 78 dB -26.6 dBm 62 dB -38.8 dBm 77 dB -25.8 dBm 61 dB -37.9 dBm 76 dB -25 dBm 60 dB -37 dBm 75 dB -24.4 dBm 59 dB* -36.2 dBm 74 dB -23.8 dBm 58 dB* -35.4 dBm 73 dB -23.2 dBm 57 dB* -34.6 dBm 72 dB -22.6 dBm 56 dB* -33.8 dBm 71 dB -22 dBm < 55 dB* -33 dBm 70 dB*We recommend padding this level due to potential for fluctuating signal.-25 dBm is the maximum input signal level that should be applied to the repeater, even if the gain is lower than 55 dB. Input signals exceeding these thresholds will result in composite input attenuation, called “ADC Protect” (Analog to Digital Converter Protection).Output power is reduced whenever the above thresholds are exceeded by reducing the gain by 1dB for each 1 dB that the threshold is exceeded.ADC Protect should not be confused with AGC (Automatic Gain Control), which reduces gain to prevent In-Band (measured) output power fromexceeding the specified maximum output level. To determine the total power applied to the donor and server ports, please reference the “CompositeInput” values as reported in the Web (“System Status”) or Menu (“Link Status”) interfaces (depicted and explained later in this manual).Large delta’s between in-band and composite input signals:Care should be taken to isolate the best donor site to ensure the least possible delta between in-band and composite downlink signals. If the(downlink) composite input exceeds the in-band input by more than 3 dB for the LTE band the maximum output power will be reduced. Example: Band (LTE) In-Band Input -45 dBm Composite Input -33 dBm Max Gain = 70 dB Max Output = 25 dBm
- 11 -Mounting the Digital RepeaterThe following diagrams illustrates the methods for mounting the repeater(s) in a typical wall or rack installation.Brackets are provided for both options. Rack mount of the repeaters requires just two brackets mounted to the front corners of each module. Note: the CSI digital repeatersmust be supported in the rack system with a shelf or slide rail. Do not rely on the brackets exclusively to support all theweight of the modules. Mount the Cross Band Coupler on the wall close enoughto the repeater modules to allow the RF jumpers to reachfrom the CBC to the repeaters. The attachment systemused to anchor the CBC to the wall must be able tosupport at lease 8.4 lbs / 3.8 kg.The wall anchoring system you use for the repeaterswill need to be able to support at lease 39.2 lbs/ 17.8kg for each dual band module and 23.2 lbs/ 10.5 kg foreach single band add on module. The power suppliesare mounted approxamately as shown.Interconnection of the repeaters in the rack mount configurationrequires the short RF Jumpers supplied with the CBC Module.One will connect from the server port of the dual band module tothe 800MHz/1900MHz port on the CBC module. The other willconnect from the server port on the single band module to the700MHz port on the CBC module. Wall mount interconnection requires one connectionfrom the server port of the dual band module to the portlabeled “High” on the Cross Band Coupler. The other willconnect from the server port on the single band moduleto the port labeled “Low” on the CBC.

This feedbackcan cause the amplifier to emit a continuous signal at maximum amplitude and, in some cases, interfere with normal operation of thedonor site. Careful consideration of the layout and placement of the system is imperative to minimize this possibility and to minimizethe amount of signal leaking from the building. See installation tips below for general guidelines.•The installer should refer to the Safety Guidelines section on page 4 and the Important Safety Information section on page 5 forproper antenna selection and installation. To avoid serious injury or death and damage to the repeater, do not install donor or serverantennas near overhead power lines or high power components. Allow enough distance so that if antennas should fall they will notcome in contact with those components.•••••Close proximity to the donor or server antennas with the repeater in operation may expose the user or installer to RF fields thatexceed FCC limits for human exposure.WARNING! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A HANDSET IS CONNECTED DIRECTLY TO THE REPEATER OR THE COAXTHAT LEADS TO THE REPEATER.Important Installation NotesDonor Antenna1. Accurately determine the azimuth to the donor cell site . Obtain the donor site information and approval fromthe service provider/carrier.2. Ensure that the radiation path to the donor cell site is as unobstructed as possible.3. Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Try to avoid having theRF signal from the donor pass above the location(s) of the service antennas. Normally the service antennas will bebehind and below the donor antenna if viewed from above. This approach will help avoid interference and feed backboth, to and from the service antennas.4. Normally mounting the donor antenna higher will allow a less obstructed path to the donor site. However, in hightraffic metro areas avoid mounting the donor antenna any higher than necessary as the quality of the donor signal maystart to become less stable and it is more likely to encounter adjacent channel interference.5. When possible shield the donor antenna’s back side by locating it so that any HVAC units and/or penthouse struc-tures are behind the antenna relative to the donor cell site location.Installation TipsIndoor Antennas1. Use omnidirectional antennas (see optional accessories) indoors, and locate them centrally with respect to theintended coverage area to minimize signal leakage to the outside. Use directional antennas indoors only in special caseswhen higher gain and directionality would be helpful and RF exposure limits will not be exceeded.2. To avoid repeater uplink overload and gain limiting mount the indoor antennas away from areas where mobile subscrib-ers frequently use their phones such as desks or dispatch areas.•Cross Band Couplers Quad band Rack Mount: CSI-CM250-7/C/AW/P (700 LTE, Cell, AWS and PCS) Quad band Wall Mount: CSI-CBC/696-2170/N (700 LTE, Cell, AWS and PCS) Tri band Rack Mount: CSI-CM250-U7C/C/P (700 Upper C LTE, Cell and PCS) Tri band Wall Mount: CSI-CBC21/740-1990/N (700 Upper C LTE, Cell and PCS) Tri band Rack Mount: CSI-CM250-L7AB/C/P (700 Lower A/B LTE, Cell and PCS) Tri band Wall Mount: CSI-CBC21/696-1990/N (700 Lower A/B LTE, Cell and PCS)
-13-The repeater uses a single down-conversion/up-conversion scheme. There are multiple RF amplifier stages prior to each down-convertingmixer. The down-converting mixers are followed by a single IF amplifier. A Digital Signal Processor block then processes the resultant digitizedIF signal that was previously generated by an Analog-to-Digital Converter. The processed (filtered) digital signal is fed to a Digital-to-Analogconverter and then up-converted to RF. A driver amplifier and a final power amplifier make up the final gain stages before application to thediplexer. The maximum total system gain (diplexer input to diplexer output) is nominally 85 dB for either the downlink or the uplink paths withboth links having independent manual and automatic gain controls (AGC).AGC reacts to analog power detection on both the input and output of the uplink and downlink RF chains. A control algorithm continu-ously monitors these detected values and dynamically adjusts various gain stages such that the net system gain value, enteredmanually, is maintained without either exceeding FCC parameters or overdriving the A/D converters.Circuit Operational DescriptionFunctional Block DiagramUpon detection of oscillation the unit will shut down. After a “short duration” of 30 seconds the unit will attempt normal operation. If no continuedoscillation is occurring the unit will stay on. However, if oscillation is still occurring, the repeater will remain shut down and retry 1 additional time inthe “short duration” loop. If after these two “short duration” retries, the oscillation is still detected, it will turn off again and wait a “long duration” periodof 10 minutes. If after 6 “long duration” retries, oscillation continues, the unit will go into a “disable duration” of 24 hours. It will continue in the “disableduration” loop and retry every 24 hours.LED on the front panel display provide immediate visual indications of the unit’s primary power and major or minor alarm status. Therepeater features automatic shutdown protection, as a safety measure, should excessive drive be applied to the input or an oscillationcondition occur. When in a protected mode, a control algorithm determines the appropriate method of recovery to a normal, previouslydefined state, or maintains the protection until manually reset.Indoor Antennas continued3. To determine the quantity and locations of indoor antennas, use an appropriate phone's signal meter to determine areasof weak signals. These are the approximate areas where indoor antennas may be needed. Also be aware the signal froman indoor antenna, in most cases, can be expected to penetrate about two standard office sheetrock type walls to reachusers. After two walls or if the walls are made of other materials, it may be necessary to split the available signal and addmore antennas.

-17-When login is complete the user is brought to the system status page. The links shown in thenavagation box on the left are activated by clicking on them.Primary access to the repeater is gained using a LAN connection and a web browserprogram such as Firefox by Mozilla, or Internet Explorer from Microsoft. The repeater shipswith the default IP address of 192.168.1.100, but it can be changed later if required.If connecting directly to the repeater from a laptop or PC with a crossover CAT-5E cable orover a LAN the user types the IP address of the repeater into the browser address line toconnect. (Note: Most users will need to update the TCP/IP settings on their computer to enableconnection to a host that has a static IP. Select “Use the following IP Address” and enter the IPAddress as follows: 192.168.1.x, where “x” = any number from 2 to 254 inclusive other than100. The subnet mask is 255.255.255.0. Questions pertaining to these settings should bereferred to the user’s IT department or you may refer to the Additional Tips section at the endof this manual.) When connection is made the user will be prompted for a user name andpassword. For the purpose of the GUI session, the default user name is webuser and thepassword is csi1234. This can also be changed as required. Internet access is not requiredto use the GUI. (Note: If you are connecting using a laptop, verify that your Ethernet port ispowered. Some laptops will not allow Ethernet connection when on battery power. If this isthe case with the laptop you are using you will need to plug it in or update the power settings.)System Status:Web based GUI Session

-23-To end the session exit the browser, the user will be automatically logged out.Figure 1 Figure 2Local access to the repeater TMI, also known as the console interface, is made by connecting a serialcable (optional), as shown in figure 1, from the serial connector of the laptop to either of the serial ports onthe bottom end panel of the repeater. These connectors are labeled COM 1 and COM 2. In some cases, ifthe gender of the connector is not the same as shown in figure 1, a null modem adapter (optional) as shownin figure 2 may also be required.Text Menu Interface (Local Access)By clicking on the Change Password link the user is brought to the Change Password page. From here he or she canquickly and easily reset the password for the unit. A word of warning here be careful when setting the new password. Ifyou forget what you set your password to you’ll need to contact CSI at 1-877-844-4274 for assistance.Change Password:
-24-Many terminal emulation programs will work if properly configured. In the following description,“TeraTerm” is used to establish the TMI session. This program is readily available via the Internetand is free from Ayera Technologies at:http://www.ayera.com/teraterm/TeraTerm Pro Web works on Windows 95/98, 2000, XP. Here is the latest TeraTerm Pro Webrelease: Version 3.1.3, October 8, 2002. ttpro313.zipWhen the program is started, the following screen is displayed.Select the Serial radio button and press OK as shown below.Note: It may be necessary, in the System Properties section of the control panel; using DeviceManager to determine what COM port your computer uses for the communications port. In this caseit is COM 1. This is not to be confused with the serial port on the bottom panel of the repeaterlabeled COM 1.Terminal Emulation Program
-25-Pressing “OK” will open up a blank dialog screen. Go to the setup dropdown menu andselect Serial port to make changes to the serial port setup.Configure the terminal program for the correct COM port, in this case COM 1 and 115200baud rate as shown below.Terminal Emulation Set-up
-26-After completing the serial port changes (pressing the enter key will be required to completethe action) the user will be prompted for a user name and password. The default user name is“user”. The password is “csi1234”. After entering the password and pressing return theTMI main menu will appear. Note: by default the Set Parameters option is disabled. To re-enablethe user will press 1 and will be prompted for a username and password. The default username is csi and the password is csi1234.The actions displayedare self-explanatory.Pressing “1” willcontinue to expand thissession screen andallow the followingparameters to be set.TMI Login
-27-After selecting option 1, downlink, the current user gain is displayed and the option to change itis accomplished by typing the desired gain at the prompt. The user is then returned to theprevious menu.Each “Set Parameter” selection, when chosen will be expanded to allow changing or setting of thatparameter. For example from the Link Configuration menu on the previous page, selecting 1 - AdjustGain will display the menu shown below.
-28-All the other options operate in much the same way. Some of the options will offer the useradditional selections and will be self-explanatory. Below is one example of these additional options,the one shown below is the result of selecting (3) Filter Programming.Note: Graceful session termination is important. Use Disconnect under the file dropdown menuto terminate a session, otherwise the port may become disabled and force the system to berebooted.Remote access to the repeater may be gained through a LAN connection and a terminalemulation program for TCP/IP. As with the serial connection, many terminal emulation programswill work, if properly configured. In the following description, “TeraTerm” is used to establish theTelnet session. Also, it will be required that the network configuration of the computer and therepeater being controlled be set up with the same Sub Net and Sub Net Mask in order to establisha link. In other words, the IP addresses of both the computer used and the repeater must use thesame group of IP address number sets. For example, the repeater ships with the default IPaddress of 192.168.1.100 and a Sub Net Mask of 255.255.255.0. In order to connect, thecomputer to be used for the link would normally need an IP address of something like192.168.1.12 with a Sub Net Mask of 255.255.255.0, the same Sub Net Mask as the repeater. Inthis example note: the last digit of the IP address may be any number except 1,100 and 255.Configuring your PC is normally fairly straight forward but it does vary somewhat with theoperating system involved. If you require assistance, contact your IT department and they willbe able to set up your PC for you or you may review the Additional Tips Section at the end of themanual.When the TeraTerm program is started, the following screen is displayed. Change the defaulthost IP address to the IP address of the repeater to be controlled. In the case of a new install, thedefault address is 192.168.1.100 and has been assigned at the factory. Select the serviceTelnet. The TCP Port must be 23.Telnet Session (Remote Access)
-29-Pressing the “OK” button will bring the user to the following screen, which will require the userto log in. The default user name is “user”. The default password is “csi1234”.In the field after the prompt “DSP85-cell-X login;” type the user name and password. After typingthe password press the enter key and the main menu will be displayed as shown next.Telnet Session Login
-30-Telnet and serial sessions both provide access to the same Text Menu Interface. Wehave already shown many of the options available and all are self explanatory, so theywill not be repeated.A modem can also be used to gain remote access to the unit provided the repeater has beenproperly equipped. A selection of modems is available as an option. If the modem requires a SIMcard for activation, special requirements must be met for the SIM card to become fully functional,contact the service provider. In addition, an IP address must be obtained and entered into the CSI-DSP85-PSS8.Once the modem has been installed and activated, it can be accessed from any terminal emulationprogram just as in the serial and Telnet examples provided earlier. Access response time willdepend on many factors, some of which are:•Quality of the connection (RF signal in the case of wireless modems)•Technology (CDMA, EDGE, GPRS, etc.)•Network congestion (Throughput)When a connection has been established, the same login screen shown in both the serial andTelnet examples is presented.Modem Interface (Remote Access with login)
-31-Instructions to change TCP/IP settings on your Windows computer.Click in the Network Connections Icon in the Control Panel. See below.Right click on Local Area Connection - and select “Properties”.Scroll down to “Internet Protocol (TCP/IP) and click on the “Properties” button.Additional Tips
-32-If you are set up to use DHCP, the window shown below will be displayed.Select “Use the following IP address:” and enter “192.168.1.2.” The subnet maskshould automatically populate to “255.255.255.0”.Nothing else will need to be chosen or entered. Click “OK”, then “OK again andretry connection.A crossover Ethernet cable (supplied) must be used for Web Interface access. Asa reminder, you must verify the Ethernet port on your laptop is powered. If yourlaptop is on battery power, the Ethernet port may be inactive by default. If this isthe case simply plug in the laptop to a 110vac source or change the power settingsto enable the Ethernet port when the laptop is using battery power.
-33-When troubleshooting RF issues, and when surveying challengingRF environments, it’s important to have a spectrum analyzer capableof measuring the frequency that you are working with. An attenua-tor should be used to protect the input, when connected to a sourceof RF power such as the repeater or a powered DAS.Both Uplink and Downlink should be measured. Downlink should bemeasured on the donor cable and at the output (server) port of thepowered up repeater, and Uplink at the lead from the DAS (on fiber/powered DAS’s, where the lead would connect to the server port onthe repeater) and at the donor port with the repeater powered up.Measurements may also be necessary at server antenna locations.Your spectrum analyzer will need to be equipped with a whipantenna for this.Resolution Bandwidth (RBW) should be set at 200 kHz for GSM and 1MHz for CDMA. If you cannot select these values, the closestavailable values should be used. Video filter should be about onetenth of RBW. Other settings like span are whatever is appropriate.One should also make sure that there are no signals above the topof the screen.If you cannot see an adjacent out of band signal when using the 1MHz RBW filter, you can decrease the RBW, to see the close-in-frequency signals. Be sure to set the RBW back when you want tomeasure the power level.Suggested spectrum analyzer setting:RF Notes:To prevent overload of the DSP input stages, the maximum measuredlevel of in-band or out of band signals should be less than -50 dBm whenthe DSP gain is set to 85 dB, -40 dBm when set to 75 dB, etc. This applieswhen there is one dominant signal and applies TO BOTH THE DOWNLINKAND UPLINK. If there are two dominant signals, and the gain is set to 85dB, then the level of each signal should be kept to less than -53 dBm.With three signals, each should be less than -55 dBm. With ten signalseach should be less than -60 dBm. This latter reduction prevents thecomposite power of the multiple signals from exceeding an acceptablelevel. Add fixed attenuators in line with the donor antenna line/DAS feedto keep signals below the levels indicated above.
