- 5 -Product IntroductionCellular Specialties, Inc. (CSI) developed this digital repeater for use within enclosed structures wheresufficient signal from local cell sites to operate wireless phones is unavailable. Adequate signal must beavailable outside the structure as a prerequisite to achieving in-building coverage. The Digital Repeater isconnected to an external antenna, usually on the roof, and to one or more internal antennas placedstrategically throughout the area where wireless service is desired.The external antenna typically is directional, such as a “yagi”. Internal antennas are typically omnidirec-tional, although various other types may be used depending on the coverage application. The repeateramplifies both the “uplink”(phone to tower) & “downlink”(tower to phone) signals thus facilitatingcommunications 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 arange from +53.5dB to +85dB in 0.5dB steps. Control of the repeater is achieved utilizing a computerconnected to comm. port 1 or 2 or via a Crossover Ethernet cable connected to the Ethernet port. Thereare also an LED indicator indicate ALARM status.A specific filtering process modifies each amplification chain. This process digitally converts the assignedspectrum and then applies digital signal processing (DSP) techniques. DSP is used to create passbandsthat selects the RF energy passing through either the uplink or downlink paths. After the digital processingis complete, the information is converted back to an analog signal that is applied to the remaining stagesof amplification. The resulting signals emitted by the repeater are specific to the network service providers’requirements. If these requirements change, only the DSP configuration parameters need change in orderto adapt. Configuration parameters are created at the factory and supplied as files that may be down-loaded to the repeater. The filter set configurations stored in memory determine the unit’s adaptability tovarious field applications. The following pages describe the PCS band plan as well as the convention CSIuses to identify and store the files that make up the filter set.  All units are shipped with an active filter setthat is programmed according to the ordering parties’ specifications.  In most cases, the installer will nothave to program a filter.Important Safety InformationAntennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. 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 183 cm. (~6 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.Terms Used in This ManualAGC= Automatic Gain Control ERP= Effective Radiated PowerAPC= Automatic Power Control FCS= Feedback Cancellation SystemAUI= Attachment Unit Interface FPGA= Field Programmable Gate ArrayCPU= Central Processing Unit LED= Light Emitting DiodeCSI= Cellular Specialties, Inc.

In the vast majority of cases this information will not beneeded.Local Communication Interface PortsTo allow monitoring and control, the repeater is equipped with four ports that provide externalcommunication access (1 Ethernet CAT-5, 2 DB-9 serial, and 1 USB). The Ethernet, CAT-5 portis provided as a primary communications port to the PC. One serial interface provides commu-nications to local PC and the second to an external modem when provided. The  USB interfaceprovides a means to download files from a memory device and may also be used by anexternal modem.  The DB-9 pin assignments conform to the standard Electronic IndustriesAssociation (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 emulationprogram with a PC will allow communication to the control processor’s Text Menu Interface(TMI). See command line interface section for further detail.Monitoring & AlarmsThere are no physical connections provided to specifically communicate system or alarmstatus. This information is embedded in the information accessible via the communicationports described earlier.USB InterfaceThe Universal Serial Bus (USB) interface conforms to Intel’s Universal Host ControllerInterface (UHCI) version 1.1 dated March 21, 1996. This interface will support datatransfer rates up to 12 Mbps and can be used for software updates and filter fileuploads.EthernetThe 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.
-10-System Set-Up ConsiderationsAll cables should be checked for shorts and opens. Also verify that there are no cables with loose or poorconnections. 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 itmay not always be so. It is critical the installer contact the service provider for information on, andapproval of, the cell 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 repeater is operating. The existence of strong  adjacent channelsignals within the frequency band(s) can cause the AGC to reduce the amplifier’s gain or cause alarms. In somecases additional filtering or attenuation might be required to reject these unwanted signals. In some instances, thedonor antenna can be reoriented horizontally, to place the interference source in an antenna pattern “null”. Therealso may be some cases where the interference from outside signals is so great that they cannot be filtered orotherwise reduced or eliminated without expensive and possibly prohibitive measures. In these cases it may notbe practical to use the repeater for providing coverage to these sites.Selection of external attenuators to be used in line with the Antenna Port(s):1:1 PORT CONFIGURATION   Input: One single band duplex port, from the dual band donor.Output: One single band duplex port to the DAS.DONOR PORTIf a unit is installed in an area with very strong desired and/or undesired signals, it is important to ensure that theoverall signal levels are optimized to be within the best operating range of the repeater.  Additionally, de-sensing of anearby base station site must be avoided.  These goals can be accomplished by properly attenuating the antennaport(s) in the path of the donor antenna(s).  In effect, one can imagine that the particular repeater deployment iselectrically moved farther from the base station using attenuators that are equivalent to increasing the path loss fromthe donor antenna to the base station. The following potential outcomes result from the use of attenuators on thedonor port(s) of the repeater:  Uplink output power, as reported by the unit, is reduced by the value of the attenua-tion, protecting nearby base stations.  Downlink signal to noise ratio is high at the point of the attenuator, resulting inslight but negligible reduction in downlink performance. Other performance is essentially unchanged.SERVER PORTServer port attenuation may also be necessary, particularly where a powered DAS is present.  The selection guide-lines below apply to both server and donor ports.  In order to properly measure uplink signal strength, a signalgenerator should be used.  If a signal generator is not available, placing a test call while under the server antennawith 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 repeater:  Downlinkoutput power, as reported by the unit, is reduced by the value of the attenuation.  Uplink incoming power from theDAS is reduced, along with potentially strong and/or harmful out-of-band signals (including noise) that are generatedby the DAS.
-11 -Attenuator Selection Guidelines:Accurate attenuator values need to be chosen to ensure that the maximum total power (higher of Composite or In-Band Input) applied to the donor and 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 DigitalConverter Protection).  Output power is reduced whenever the above thresholds are exceeded by reducing the gain by 1dB foreach 1 dB that the threshold is exceeded.  ADC Protect should not be confused with AGC (Automatic Gain Control), whichreduces gain to prevent In-Band (measured) output power from exceeding the specified maximum output level.To determine the total power applied to the donor and server ports, please reference the “Composite Input” values as reported inthe 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 downlinksignals.If the (downlink) composite input exceeds the in-band input by more than 5 dB, the maximum output power will be reduced.Example:                                                                                                AWS Band                                                                                                In-Band Input -45 dBm                                                                                                Composite Input -38 dBm                                                                                                 Max Gain = 68 dB                                                                                                 Max Output = 23 dBm
-12 -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. Note: Dual and single band modules are shown for illustration purposes. 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.
- 13 -Circuit Operational DescriptionThe repeater uses a single down-conversion/up-conversion scheme. There are multiple  RF amplifier stagesprior to each down-converting mixer. The down-converting mixers are followed by a single IF amplifier. A DigitalSignal Processor block then processes the resultant digitized IF signal that was previously generated by anAnalog-to-Digital Converter. The processed (filtered) digital signal is fed to a Digital-to-Analog converter and thenup-converted to RF. A driver amplifier and a final power amplifier make up the final gain stages before applicationto the diplexer. The maximum total system gain (diplexer input to diplexer output) is nominally 85 dB for either thedownlink  or the uplink paths with both 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 continuously monitors these detected values and dynamically adjusts various gainstages  such that the net system gain value, entered manually, is optimally maintained without eitherexceeding FCC parameters or overdriving the A/D converters.An LED on the front panel provides immediate visual indications of the unit’s primary power and major orminor alarm status. The repeater features automatic shutdown protection, as a safety measure, shouldexcessive drive be applied to the input or an oscillation condition occur. When in a protected mode, acontrol algorithm determines the appropriate method of recovery to a normal, previously defined state, ormaintains the protection until manually reset. If recovery has been established, the LED will either beextinguished or available to be reset. The events that trigger the error will be saved in the event log.Important Installation Notes•Inadequate isolation between the outside and inside antennas may cause regenerativefeedback in the system. This feedback can cause the amplifier to emit a continuous signal atmaximum amplitude and, in some cases, interfere with normal operation of the cell site. Carefulconsideration of the layout and placement of the system is imperative.•The installer should refer to the Safety Guidelines section on page 4 and the Important SafetyInformation section on page 5 for proper antenna selection and installation. To avoid serious injury ordeath and damage to the repeater, do not install donor or server antennas near overhead power linesor high power components.   Allow enough distance so that if antennas should fall they will not comein contact  with those components.•••••Close proximity  to the donor or server antennas with the repeater in operation may exposethe user or installer to RF fields that exceed FCC limits for human exposure.WARNING!

- 18 -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
- 19 -After any changes are made press the refresh button to review the fields and ensurethe change made is correct. Note: changing network settings will cause the current TCP/IPconnection to fail because the change will  take effect immediately. From here the user may returnto the System Status screen or click on the other options.If the user selects Local Network from the System Status page, the following screen is displayedand from here network configuration can be modified as required. The default is set to Static. Checkwith your IT department for explanation and approval of the DHCP and DHCP Server options youplan to use before you select them. *NOTE:  In units with software version 2.2.4 or prior, onlyletters, numbers and underscores are acceptable nomenclature.  In units with software version2.3.0 and up, Underscores are not acceptable; however, hyphens are acceptable.Local Network:
- 20 -If the user would like to modify RF configuration click on the words RF Configuration in thenavigation box and the screen below is displayed.The user may select the desired filter by pressing the band/sub-band and modulation selectionbuttons. Undesired bands/sub-bands if lit will require the user to manually “deselect” them beforeprogramming.   Pressing the Program button will complete the selection and load the desired filter.The time required to complete this process will take just a few moments.  Note: If the filter desiredis not currently in the unit, additional filters along with instructions on how to load them areavailable by contacting CSI.To change gain settings the user will select the Uplink only or Uplink and Downlink radio buttons.The user then inputs the gain value desired. Gain values from 53.5 dB to 85.0 dB may be selected.The repeater will not allow the user to set values outside this range. By pressing the ChangeSettings button the gain change is implemented.  When a new filter set is required, it may beselected by clicking Program a Filter in the navigation box.RF Configuration:Program a Filter:
- 21 -To change SNMP settings select SNMP Configuration in the navigation box, the screen below willbe displayed. If the user is not well versed in Simple Network Management Protocol he or sheshould check with their IT professional for proper setting requirements.Remote Network:SNMP Configuration:If the repeater includes a USB modem kit, click on Remote Network in the navigation box and thescreen below is displayed. Highlight the carrier on whose network the repeater and modem will beconfigured and click the Change Settings button. Refer to the documentation included with themodem kit for addtional information on configuring the modem. If the repeater is connected to anethernet device for remote access and/or monitoring, this feature must be disabled.
- 22 -By clicking System Health the current state of the repeater can be reviewed.***The user may clear LED indicator, alarms and the Event Log by clicking the Clear Log button.***System Health:Should a software install or upgrade be needed it can be done from the Install & Upload screenshown below. As with the other screens it can be reached by clicking the words in thenavigation box. Contact CSI for updates and instructions.Install  & Upload:**** If required in your market, visit the “System Health” screen and click on “Trigger Test Alarm”and wait for confirmation that the Wireless Service Provider representative that is responsiblefor monitoring the repeater has been notified of the alarm. Be sure to “Clear All Logs” prior tologging out of the Web Interface.****

-25 -Figure 1 Figure 2Text Menu Interface (Local Access)Local access to  the repeater TMI, also known as the console interface, is made by connecting aserial cable (optional), as shown in figure 1, from  the serial connector of the laptop to either ofthe serial ports on the bottom end panel of the repeater. These connectors are labeled COM 1 andCOM 2. In some cases, if the gender of the connector is not the same as shown in figure 1, a nullmodem adapter (optional) as shown in figure 2 may also be required.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.
-26 -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.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 repeater labeled COM 1.
- 27 -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 default password  “csi1234”.  After entering the password and pressing enterthe  TMI main menu will appear. Note: by default the Set Parameters option is disabled. To re-enable the user will press 1 and will be prompted for a username and password.   The defaultuser name 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.
- 28 -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.
- 29 -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.Telnet Session (Remote Access)Remote access to the repeater may be gained through a LAN connection and a terminal emula-tion program for TCP/IP. As with the serial connection, many terminal emulation programs willwork, if properly configured.  In the following description, again, “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 of the repeater must bethe same 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 Tera Term program is started, the following screen is displayed. Change the default hostIP 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 service Telnet.The TCP Port must be 23.
- 30 -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”.In the field after the prompt type the user name. The default password  is “csi1234”.  After typingthe password press the enter key and the main menu will be displayed as shown next.
- 31 -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.Modem Interface (Remote Access with login)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 therepeaterOnce 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.
- 32 -Additional TipsInstructions 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.
- 33-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.
- 34 -When troubleshooting RF issues,  and when surveying challenging RF environ-ments, it’s important to have a spectrum analyzer capable of measuring thefrequency that you are working with.  An attenuator should be used to protect theinput, when connected to a source of RF power such as the repeater or apowered DAS.Both Uplink and Downlink should be measured.  Downlink should be measuredon the donor cable and at the output (server) port of the powered up repeater,and Uplink at the lead from the DAS (on fiber/powered DAS’s, where the leadwould connect to the server port on the repeater) and at the donor port with therepeater powered up.  Measurements may also be necessary at serverantenna locations.  Your spectrum analyzer will need to be equipped with awhip antenna for this.Resolution Bandwidth (RBW) should be set at 200 kHz for GSM and 1 MHz forCDMA.  If you cannot select these values, the closest available values shouldbe used.  Video filter should be about one tenth of RBW.  Other settings likespan are whatever is appropriate.  One should also make sure that there areno signals above the top of the screen.If you cannot see an adjacent out of band signal when using the 1 MHz RBWfilter, you can decrease the RBW, to see the close-in-frequency signals.  Besure to set the RBW back when you want to measure the power level.RF Notes:To prevent overload of the DSP input stages, the maximum measured level ofin-band or out of band signals should be less than -50 dBm when the DSP gainis set to 85 dB, -40 dBm when set to 75 dB, etc.  This applies when there isone dominant signal and applies TO BOTH THE DOWNLINK AND UPLINK.  Ifthere are two dominant signals, and the gain is set to 85 dB, then the level ofeach signal should be kept to less than -53 dBm.  With three signals, eachshould be less than -55 dBm.  With ten signals each should be less than -60dBm.  This latter reduction prevents the composite power of the multiplesignals from exceeding an acceptable level.  Add fixed attenuators in line withthe donor antenna line/DAS feed to keep signals below the levels indicatedabove.Suggested Spectrum Analyzer Setting:
