Following the proceduresoutlined will minimize risks associated with modifying a live system and prevent serviceinterruptions. This document assumes the technician/engineer understands the basic prin-ciples and functionality involved with Repeater and in-building systems. It is geared to thepractical concerns of the installer.

- 5 -Product IntroductionCellular Specialties, Inc. (CSI) developed the DSP85 and DSP85I digital repeaters for use within enclosedstructures where sufficient signal from local cell sites to operate cell phones is unavailable. Adequatesignal must be available outside the structure as a prerequisite to achieving in-building coverage. TheDigital 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 omnidirec-tional, although various other types may be used depending on the coverage application. The CSI DSPRepeater amplifies both the “uplink” (phone to tower) & “downlink” (tower to phone) signals thusfacilitating 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 arange from +53.5dB to +85dB in 0.5dB steps. Control of the repeater is achieved utilizing a computerconnected to com port 1 or 2 or via a Crossover Ethernet cable connected to the Ethernet port. There arealso 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 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 Cellular and PCS band plans as well as theconvention CSI uses to identify and store the files that make up the filter set. All DSP85-C/P andDSP85I-C/P repeaters are shipped with an active filter set that is programmed according to the orderingparties’ specifications. In most cases, the installer will not be required to program a filter.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.

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.

In the case of a catastrophic systemevent, a shutdown circuit is incorporated that will disable all emissions should the uplink input or downlinkinput be over driven or should an oscillation or output overpower event occur. The amplifier will periodi-cally attempt to recover from the detected condition automatically. Warning light indicators are as follows:

EIA232 Pin SpecificationsUSB 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.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.The 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 anunusual connector configuration. 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.- 10 -

-11 - System Set-Up ConsiderationsAll 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 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 not bepractical to use the repeater for providing coverage to these sites.Selection of external attenuators to be used in line with the CSI-DSP85 AntennaPort(s):DONOR PORTIf a CSI-DSP85-C/P or CSI-DSP85I-C/P is installed in an area with very strong desired and/or undesired signals, itis important to ensure that the overall signal levels are optimized to be within the best operating range of therepeater. Additionally, de-sensing of a nearby base station site must be avoided. These goals can be accom-plished by properly attenuating the antenna port(s) in the path of the donor antenna(s). In effect, one can imaginethat the particular repeater deployment is electrically moved farther from the base station using attenuators thatare equivalent to increasing the path loss from the donor antenna to the base station.The following potential outcomes result from the use of attenuators on the donor port(s) of the repeater: Uplinkoutput power, as reported by the unit, is reduced by the value of the attenuation, protecting nearby base stations.Downlink signal to noise ratio is high at the point of the attenuator, resulting in slight but negligible reduction indownlink performance. Other performance is essentially unchanged. Input: Two single band duplex ports, one from the cell donor and one from the PCS donor.Output: One dual band duplex port to the DAS.

-12-SERVER PORTServer port attenuation may also be necessary, particularly where a powered DAS is present. The selection guidelinesbelow apply to both server and donor ports. In order to properly measure uplink signal strength, a signal generatorshould be used. If a signal generator is not available, placing a test call while under the server antenna with the leastpath 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 the DASis reduced, along with potentially strong and/or harmful out-of-band signals (including noise) that are generated by theDAS.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 3 dB Cellular, or more than 5 dB PCS, the maximumoutput power will be reduced. Example: Band 1 (Cellular) In-Band Input -45 dBm Composite Input -33 dBm Max Gain = 70 dB Max Output = 25 dBm

Wall Mounting the Digital RepeaterThe following diagram illustrates the best method for mounting the repeater to a wall in a typical installation.

Circuit Operational DescriptionThe repeater uses a single down-conversion/up-conversion scheme. There are multiple RF amplifierstages prior to each down-converting mixer. The down-converting mixers are followed by a single IFamplifier. A Digital Signal Processor block then processes the resultant digitized IF signal that waspreviously generated by an Analog-to-Digital Converter. The processed (filtered) digital signal is fed to aDigital-to-Analog converter and then up-converted to RF. A driver amplifier and a final power amplifiermake up the final gain stages before application to the diplexer. The maximum total system gain (diplexerinput to diplexer output) is nominally 85 dB for either the downlink or the uplink paths with both linkshaving independent manual and automatic gain controls (AGC).AGC reacts to analog power detection on both the input and output of the uplink and downlink RFchains. A control algorithm continuously monitors these detected values and dynamically adjustsvarious gain stages such that the net system gain value, entered manually, is maintained withouteither exceeding FCC parameters or over driving the A/D converters.LEDs on the front panel display provide immediate visual indications of the unit’s primary power andmajor or minor alarm status. The repeater features automatic shutdown protection as a safetymeasure should excessive drive be applied to the input or an oscillation condition occur. When in aprotected mode, a control algorithm determines the appropriate method of recovery to a normal,previously defined state, or maintains the protection until manually reset. If recovery has beenestablished, the associated LED(s) will either be extinguished or available to be reset. The eventsthat trigger the error will be saved in the event log.-14 -Optional AccessoriesA complete line of accessories is available from Cellular Specialties, Inc.

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 injuryor death and damage to the repeater, do not install donor or server antennas near overheadpower lines or high power components. Allow enough distance so that if antennas should fallthey will not come in 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! AMPLIFIER OR HANDSET DAMAGE MAY OCCUR IF A HANDSET IS CONNECTEDDIRECTLY TO THE REPEATER OR THE COAX THAT LEADS TO THE REPEATER.

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:

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.After changes are made, press the refresh button to review the fields and ensure thechange made is correct. Note: changing network settings will cause the current TCP/IP connec-tion to fail because change will take effect immediately. From here the user may return to theSystem Status screen or click on the other options.- 20 -Local Network:

- 21 - If the user would like to modify RF configuration, click on the words RF Configuration in thenavigation box and the screen below is displayed.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 values outside this range. By pressing the Change Settings button thegain change is implemented.RF Configuration:

When a new filter set is required, it may be selected by clicking Program a Filter in the navigationbox. The user may select the desired filter by pressing the band/sub-band and modulationselection buttons. Undesired bands/sub-bands, if lit, will require the user to manually “deselect”them before programming. To aid the user a clear all button is provided on the PCS band and willdeselect all band and sub-bands simultaneously. Pressing the Program button will complete theselection and load the desired filter. The time required to complete this process will take just afew moments. Note: If the filter desired is not currently in the unit, additional filters along withinstructions on how to load them, are available by contacting CSI.- 22 -Program a Filter:

Note: a reboot will take 3-5 minutes to complete.Reboot:The Log Configuration page provides the user with the means to change three aspects of howlog files are created and stored as shown below.Log Configuration:To end the session: exit the browser, the user will be automatically logged out.

-27 -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.Text 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.Figure 1 Figure 2

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 unit labeledCOM 1.- 28 -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.System Status Screen Single Band 7-22-09a

-29 -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. In dual band units eachband is changed independently and requires an independent login. To make changes to thecellular band, the default user name is “cellband”. The user name for changing the PCS bandis “pcsband”. The password for both bands is “csi1234”. After entering the password andpressing return the TMI main menu will appear. Note: by default the Set Parameters option isdisabled. To re-enable the user will press 1 and will be prompted for a username and pass-word. The default user 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.

-30 -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.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.

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, “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 service Telnet.The TCP Port must be 23.-31 -

- 32 -Pressing the “OK” button will bring the user to the following screen, which will require the userto log in. In dual band units, each band is changed independently and requires an independentlogin. To make changes to the cellular band the default user name is “cellband”. The defaultuser name for changing the PCS band is “pcsband”.In the field after the prompt “DSP85-PCS-X login;” type the user name for the band to be changed.The default password is “csi1234” for both bands. After typing the password press the enter keyand the main menu will be displayed as shown next.

- 33 -Telnet and serial sessions both provide access to the same Text Menu Interface. Thismanual has already discussed many of the options available, those as well as theoptions not covered are self explanatory, so they will not be repeated in the ModemInterface section.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 therepeater.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.Additional TipsInstructions to change TCP/IP settings on your Windows computer.Click in the Network Connections Icon in the Control Panel. See below.

- 34 -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 mask should automaticallypopulate to “255.255.255.0.Scroll down and highlight “Internet Protocol (TCP/IP) and click on the “Properties” button.Right click on Local Area Connection - and select “Properties”.

- 35 -Nothing else will need to be chosen or entered. Click “OK”, then “OK” again and retry connection.A crossover Ethernet cable (supplied) must be used for Web Interface access. As a reminder, you must verify theEthernet port on your laptop is powered. If your laptop is on battery power, the Ethernet port may be inactive bydefault. If this is the case simply plug in the laptop to a 110vac source or change the power settings to enable theEthernet port when the laptop in using battery power.When troubleshooting RF issues, and when surveying challenging RF environments, it’s important to have a spectrumanalyzer capable of measuring the frequency that you are working with. An attenuator should be used to protect the inputwhen connected to a source of RF power such as the repeater or a powered DAS.Both Uplink and Downlink should be measured. Downlink should be measured on 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 the repeater powered up. Measurementsmay 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 1 MHz for CDMA. If you cannot select these values,the closest available values should be used. Video filter should be about one tenth of RBW. Other settings like span arewhatever is appropriate. One should also make sure that there are no signals above the top of the screen.If you cannot see an adjacent out of band signal when using the 1 MHz RBW filter, you can decrease the RBW, to seethe close-in-frequency signals. Be sure 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 of in-band or out of band signals should beless than -50 dBm when the DSP gain is set to 85 dB, -40 dBm when set to 75 dB, etc. This applies when there is onedominant signal and applies TO BOTH THE DOWNLINK AND UPLINK. If there are two dominant signals, and the gain is setto 85 dB, 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 signals each should be less than -60 dBm. This latter reduction prevents the composite power of themultiple signals from exceeding an acceptable level. Add fixed attenuators in line with the donor antenna line/DAS feedto keep signals below the levels indicated above.Suggested spectrum analyzer setting:
