This document contains Proprietary Information of Northern Telecom Limited. This information is considered to beCONFIDENTIAL and should be treated appropriately.Feasibility StudyDuring a short feasibility study a number of issues were identified when the CDMA Metrocell isto be used with the MCPA shelf to deliver maximum 50W of output power per single CDMAcarrier and 100W per two CDMA carriers measured at the MCPA shelf output port. A list ofissues that is provided in this chapter is not complete and more issues are expected to beidentified once design of the project is actively initiated.Each identified issue has been analyzed and current solutions are provided for each of the issues.Customer should provide +27V/240 Amps of current for 3 MCPA shelves.With this power level maximum 3 MCPA shelves will deliver maximum 100Wper sector or 300W per all three sectors. Customer DC power and groundingstrategy should meet Nortel and UL requirements for both CDMA Metrocelland TDMA radio frame.Design will specify the MCPA shelf DC power supply requirements and thecustomer will be responsible to procure the DC power supply that meets thespecifications. If customer procured DC power supply will not meet thespecified requirements the performance and reliability of the MCPA shelvescould be degraded.TDMA radio frame is not capable to support more than 2 MCPA shelves.Either two TDMA radio frames are to be used or additional RIP is to beinstalled in the same TDMA radio frame. Furthermore, customer could providebreakers and power cables for each MCPA shelf in order to limit a number ofTDMA radio frames.One TDMA radio frame will be limited to support 2 MCPA shelves. One RIPwith 6 breakers, 50W each, will be used for one TDMA radio frame.CDMA Metrocell customer alarms will require to develop an Alarm Box thatwill convert the MCPA shelf alarm logic to the CDMA Metrocell appropriatealarm logic.No MCPA shelf alarms will be available with the CDMA Metrocell. Thecustomer might be able to support the MCPA shelf alarms via the AMPSequipment, however design is not responsible to either verify or support theMCPA shelf alarms with the AMPS equipment.Field calibration procedure will be required to ensure that the MCPA shelf isset to the correct output power level. The accuracy of the calibration procedurewill be limited by the accuracy of the calibration equipment, MCPA shelfpower detector, CDMA Metrocell HIPD as well as attenuator and cableabsolute loss variation over the operational temperature.No additional information is available.CDMA Metrocell system reported transmitted output power will not be correctas the power level reported by the CDMA Metrocell will be derived based onthe 25W SCPA with reference to the DPM ANT port.No additional information is available.

This information is considered to beCONFIDENTIAL and should be treated appropriately.Receiver sensitivity and/or IIP3 will be somewhat impacted if the transmitsignal after the MCPA shelf is to be transmitted via the same DPM that is usedto filter and amplify the receive signal.No additional information is available.Receiver sensitivity and/or IIP3 will be impacted for configurations whereCDMA Metrocell receive signals will be shared with AMPS systems,especially after passing via the AMPS multicouplers.Excel spreadsheet is available to calculate the CDMA Metrocell degradationwith the AMPS multicouplers in-line.20 dB 150W power attenuators will require to be mounted in the TDMA radioframe where sufficient airflow is available for cooling purposes.It is recommended to mount the fixed attenuators at the back of the MCPAshelf for modular design and easy accessibility. If thermal or other mechanicalissues will be identified, the fixed attenuators will be mounted below theMCPA shelves in the TDMA radio frame.Variable attenuators will require to be mounted in the TDMA radio frame,possibly in close proximity to the MCPA shelf. In addition, variable attenuatorswill have to be easily accessible for calibration purposes in the field.It is recommended to mount the variable attenuators at the back of the MCPAshelf for modular design and easy accessibility. If thermal or other mechanicalissues will be identified, the variable attenuators will be mounted below theMCPA shelves in the TDMA radio frame.A number of new RF and DC cables will be required to interface the CDMAMetrocell with the TDMA radio frame and MCPA shelf.Development will first try to reuse currently designed and available cables fromthe CDMA product portfolio.It is recommended to provision a directional coupler at the output of the MCPAin order to monitor the output power with the external power meter when thesystem is operational as well as during the calibration process. This will ensurethat the cable between the MCPA shelf output and the duplexer will not betaken off every single time during the calibration.No additional information is available.

In thefirst case it was assumed that the CDMA Metrocell and the TDMA radio frame are separated bysome distance and the receive signals for the CDMA Metrocell are provided from AMPSmupticouplers. In both other cases it was assumed that both CDMA Metrocell and TDMA radioframe are positioned in close proximity to minimize the Tx loss or the Rx loss between theCDMA Metrocell and TDMA radio frame.Development has been requested to support only the configuration that is given in Figure 1 ofthis document. The other two configurations have been included for information and will not beverified as a part of the project. There is some risk that with the configurations that are given inFigure 2 and Figure 3 receiver sensitivity might be slightly impacted due to the higher Tx noiselevel in the receive band or higher power at the receiver front end.Please note that the information provided in Figure 1, Figure 2 and Figure 3 is generic and intended fordesign audience only. This information should not be presented to the customer until it has been approved bydesign.

However, the transmit and receive power levels reported atthe Tx and Rx DPM ANT ports will not be correct until the later system software release isavailable.CDMA Metrocell transmitted power reported by the CDMA Metrocell system software will bereferenced to the DPM ANT port. Future release of system software should have a capability toenter a loss or gain value to the reported DPM transmitted output power in order to report moreaccurately transmitted power level at the CDMA Metrocell demarcation point. Nevertheless, anyadditional HPA modules will not be calibrated over the temperature or frequency range, thus theaccuracy of the reported power level will greatly depend on the gain variation of the additionalHPA over the temperature, frequency and input power.50 W HPA PerformanceA single MCPA shelf with 3x50W MCPA units was tested to ensure that it could support 2CDMA carriers delivering 100 W of RF power at the output of the MCPA shelf without anyadditional filtering. The test results demonstrated that at room temperature single MCPA shelfcould deliver, on average, 100 W of RF power while meeting IS-97A specifications ofConducted Spurious Emissions. However, the receiver band noise was found to be some 10 dBhigher than the specified level for the 800 MHz CDMA Metrocell 25W SCPA. When used withthe CDMA Metrocell DPM, as given in Figure 3, the receiver sensitivity is expected to decreaseby approximately 1.0 dB due to excess of spurious noise in the receiver band.Tx Input and Output Power LevelsThe output power of the CDMA Metrocell PAM should not be changed in any way. In addition,all global parameters of the CDMA Metrocell should not be altered in any way to support MCPAshelf in conjunction with the CDMA Metrocell PAM. In addition, any change to the CDMAMetrocell global parameters after the MCPA shelf have been calibrated might result inoverdriving the MCPA shelf, possible damage to the MCPA shelf as well as new calibration tobe performed.A single MCPA shelf with 3x50W MCPA units is expected to meet the following powerrequirements that are given in Table 5.

This is applicable for configurations thatare given in Figure 1 and Figure 3 of this document. In Figure 1 receiver noise figure and/orIIP3 will be impacted to some extend depending on the AMPS multicoupler performance. InFigure 3 receiver noise and/or IIP3 might be impacted due to the higher spurious noise level inthe receiver band and higher power level in the transmit band.IS-97A PerformanceIt is expected that the CDMA Metrocell with the MCPA shelf delivering maximum of 100W ofRF power at the MCPA shelf output with 2 CDMA carriers should meet all IS-97Arequirements. Nevertheless, the performance of the CDMA Metrocell with the MCPA shelfdelivering maximum power level will somewhat degrade when compared with the 800 MHzCDMA Metrocell base product.MCPA Alarm SpecificationNo MCPA shelf alarms will be supported by the CDMA Metrocell. The initial requirement tosupport the MCPA shelf alarms has been removed due to time and cost constrains of the project.Customer Power Supply and GroundingDC power supply and grounding will be provided separately for each TDMA radio frame. Thisinformation is the outmost important and should be available to ensure that MCPA shelf could besafely powered up, deliver the appropriate amount of RF power and did not degraded the qualityof the CDMA transmit signal and the overall performance of the CDMA Metrocell. At thepresent time Nortel PLM has informed design that the Nortel customer will supply the DC powerthat is in agreement with the MCPA shelf specification. Should this not be the case the designwill inform the design customer, Nortel CDMA PLM group, that a different power supply shouldbe used by the Nortel customer to guarantee the performance of the MCPA shelf, safety of the

It is expectedthat after calibration has been performed and the power levels have been verified the MCPAshelf could be powered down without the need to recalibrate the MCPA shelf when they arepowered back up. However, this will be the case only if the input power to the MCPA shelf willnot changed. In other words, the calibration of the MCPA shelf should guarantee only the gainsetting, and not the output power. Should the input signal to the MCPA shelf change after it hasbeen calibrated, the output power of the MCPA shelf will also change. The accuracy of thecalibration procedure will greatly depend on the MCPA shelf power estimation accuracy, fieldcalibration equipment accuracy and the CDMA Metrocell power estimation accuracy. Based onthe above factors and currently available information it is reasonable to assume that after MCPAshelf has been calibrated the output power level of the MCPA shelf should be within 1.5 dB ofits target value (+/-0.75 dB).TDMA Radio Frame AssemblyCurrently TDMA radio frame supports maximum 2 MCPA shelves. Although there is roomavailable to position an additional MCPA shelf with 3x50W MCPA units, a single RIP isdesigned to power up maximum 2 MCPA shelves.In order to support 2 carrier 3 sector CDMA Metrocell with 50W per carrier two TDMA radioframes are required. One TDMA radio frame should have 2 MCPA shelves whereas the secondTDMA radio frame should have 1 MCPA shelf. Three sector two carrier TDMA radio frames aregiven in Figure 4.TDMA Two Radio Frame ConfigurationRIPAdditional Equipment- Attenuator BracketDuplexer Shelf RIPDuplexer Shelf 20 dB 150W Fixed 10 dB Variable2 carrier 2 sector view2 carrier 1 sector view

This information is considered to beCONFIDENTIAL and should be treated appropriately.The Attenuator Shelf might be eliminated if it will be possible to mount fixed and variableattenuators at the back of the MCPA shelf. This would allow to minimize mechanical workrequired and allow to provision a set of attenuators per each MCPA shelf. However, this solutionmust be further investigated to ensure that the MCPA shelf cooling will not be hampered as wellas the attenuators will not change its characteristics because of the MCPA shelf heat dissipation.Field Assembly and InstallationAlthough this project is developed to operate with the 800 MHz CDMA Metrocell, TDMA radioframes will be procured by the Nortel customer separately from the 800 MHz CDMA Metrocell.Furthermore, the attenuator bracket with fixed and variable attenuators as well as the interfacecables will also be ordered separately by the customer. The attenuator bracket will be assembledin the field and interfaced with the MCPA shelf and the CDMA Metrocell following instructions.

The Nortel customer is responsible to provision a DC power supply thatmeets a set of requirements specified in Table 6 and Table 7.Each TDMA radio frame is capable to support 2 MCPA shelves or 6 50W MCPA units.The DC power supply is specified for one TDMA radio frame with 2 MCPA shelves. Theoutput power per carrier should be limited to 50 W. The output power per TDMA radioframe should be limited to 200 W for a two carrier two sector configuration.MCPA shelf DC power supply specification for single TDMA radio frame is given inTable 6.#Description Specification Units Comments1Nominal Operational Voltage 27.00 VDC2Minimum Operational Voltage 21.00 VDC3Maximum Operational Voltage 30.00 VDC4Maximum Length of Stranded2/0 AWG Power Feed at 30 oC 4.6 mDistance from thepower plantcharge bar to theRIP5Maximum Power Plant VoltageDrop 0.25 VDC6Maximum Feed/Return VoltageDrop 0.25/0.25 VDC7Total RF Frame Current Draw 180 ADC 2 MCPA shelves8Minimum Voltage for Full Power 24 VDC9Absolute Maximum Voltage 30.5 VDC No Damage,appliedcontinuously10 Transient Voltage Immunity for3 ms 50 V11 TSP Shelf Inrush Current atNominal Voltage- Over 0.3 ms31 ADC12 MCPA Inrush Current atNominal Voltage- Over 0.2 ms- Over 0.5 ms- Over 1.8 ms- Over 700 ms47047038070ADCADCADCADC

Therefore, each cell site has to be inspected by the safetyauthority (UL/CSA approval in North America) such code requirements (refer to UL 1950, thirdedition/CAN/CSA C22.2 Number 950-M95) are met in order to obtain an approval from thatauthority. Site installation and power up are subject to NEC and CEC and local codes.

It is the outmost important to ensure that all equipmentis calibrated and all measurement are performed as described in this chapter in order to ensurethat the output power of the MCPA shelf is fairly accurate and close to the calibrated outputpower level.In order to ensure that the maximum MCPA shelf output power is as close as possible to 50Wper CDMA carrier it is recommended to set the CDMA Metrocell to transmit maximum outputpower during the calibration procedure. If it is not possible to set the CDMA Metrocell totransmit the maximum output power during the calibration procedure, current calibrationprocedure will change.Calibration ProcedureSet the CDMA Metrocell to output maximum power 42.72 dBm at the DPMANT port. This power level should be verified with a power meter andconfirmed with the CDMA Metrocell reported maximum Tx power level.CDMA Metrocell should be configured to generate the forward waveform withthe Overhead Channels and 6 OCNS channels.Adjust the variable attenuator until the power meter is reading +13 +/- 0.05dBm.Connect the input signal to one of 5 available MCPA input ports.Connect a calibrated 20 dB/150 W attenuator with a short cable to the MCPAoutput.Connect the power meter with a thermal sensor to a calibrated 20dB/150Wattenuator.Set the power meter Offset to the measured loss of the 20dB/150W attenuatorwith a short cable.Connect a computer with the MCPA shelf with the RS232 cable.Start Nortel Calibration Software and set Target Power to 50 W and Number ofChannels to 1.Start Calibration of the MCPA.Ensure the power level measured with the power meter and power levelreported by Nortel Calibration Software are accurate within 0.1 dB. It isimportant to remember that the power meter measurement should always beconsidered more accurate than the power level reported by the calibrationsoftware.

In both A and B cellular bands it is recommended to use the Primarychannels as the first CDMA channels for roaming and service availability. This practice iscurrently used by most Nortel customers. Based on the Primary channels initial deployment it isrecommended to introduce additional channels 42 AMPS channels apart or 1.26 MHz. This isimportant as the IMF and the Combiner are developed for a channel to channel separation of 42AMPS channels or 1.26 MHz. The list of preferred CDMA channels for the cellular band isgiven in Table 8.#Channel Rx Frequency(MHz) Tx Frequency(MHz) ChannelDeployment Comment1 31 825.93 870.93 7A Band2 73 827.19 872.19 6A Band3 115 828.45 873.45 5A Band4 157 829.71 874.71 4A Band5 199 830.97 875.97 3A Band6 241 832.23 877.23 2A Band7283 833.49 878.49 1Primary A Band8384 836.52 881.52 1Primary B Band9 426 837.78 882.78 2B Band10 468 839.04 884.04 3B Band11 510 840.30 885.30 4B Band12 552 841.56 886.56 5B Band13 594 842.82 887.82 6B Band14 758 847.74 892.74 7BÕ BandPreferred Cellular Band ChannelsPlease note that channel 758 might not meet the out of band spurious emissions, thus thischannel might not be supported.

The actual test time will take little time in comparison withthe set up time for different conditions.The following set of tests are planned to be performed at room temperature first. The same testwill be repeated over the operational temperature range with the TDMA radio frame as well asfixed and variable attenuators positioned in the temperature chamber. Please note that theMetrocell will not be placed in the temperature chamber and will always be operational at roomtemperature only. If required, the Metrocell performance over the operational temperature rangemight be analyze to derive any degradation over the temperature if both systems, CDMAMetrocell and the TDMA radio frame with the MCPA shelf were to be exposed to temperaturevariation. The TDMA radio frame with the MCPA shelf will be tested at Minimum andMaximum temperature.MCPA Calibration and Gain Variation for Single CarrierSet the Metrocell to transmit Overhead and 6 OCNS channels.Adjust the Metrocell to transmit the maximum output power.Adjust the MCPA DC power supply voltage to +27 V.Adjust a single CDMA carrier to output +13 dBm at the MCPA input.Calibrate the MCPA to generate 47 dBm at the MCPA output.Measure and record the output power over a 2 hour time period.Change the MCPA DC power supply voltage to +24 V.Measure and record the output power.Change the MCPA DC power supply voltage to +29.5 V.Measure and record the output power.Repeat the same procedure for +24 V and +29.5 V.MCPA Calibration and Gain Variation for Two CarriersSet the Metrocell to transmit Overhead and 6 OCNS channels.Adjust the Metrocell to transmit the maximum output power.Adjust the MCPA DC power supply voltage to +27 V.Adjust each CDMA carrier to output +13 dBm at the MCPA input.Calibrate the MCPA to generate 50 dBm at the MCPA output.Measure and record the output power over a 2 hour time period.Change the MCPA DC power supply voltage to +24 V.Measure and record the output power.

The MCPA shelves will come positioned at the top of the TDMA frame as shown inFigure #6, config #1. The duplexer shelf does not come standard with the TDMA frametherefore one must be ordered separately (see section 8.5 - TDMA Equipment List). It isnecessary to lower the MCPA shelves such that the duplexer shelf can be positioned above theMCPA shelves (config #2 in Figure 6). Alternatively the duplexer shelf could be mounted belowthe MCPA shelves, but it is recommended to install the duplexer shelf above the MCPA shelvesto ensure all interconnect cables will reach.Figure 7: TDMA FrameRIP RIPDuplexer Shelf(Frame without Duplexers) (Frame With Duplexers)config #1 config #2NTFC01AE NTFC01AE (modified)
This document contains Proprietary Information of Northern Telecom Limited.

It is also necessary to remove two support brackets from an empty radio shelflocation and re-install them at the duplexer location to support the duplexer shelf.Figure #7 shows a rear view of the TDMA frame with all support brackets in the correct location.The TDMA frame has markers on the left side of the frame that are spaced by 1U. Every tenthmarker is labelled with a number. Numbering starts at the bottom of the frame. Figure #10shows a more detailed diagram of the exact location of each attenuator bracket on the TDMAframe. It is important to mount all shelf support brackets in the proper location as they willdetermine the position of the duplexer shelf and MCPA shelves, which will determine theposition of the attenuator brackets. Figure 8: TDMA Frame Rear ViewThe duplexer support brackets are located such that the bottom of the brackets are in line withthe marker indicating 40U. The support brackets for the top MCPA shelf are located such thatthe bottom of the brackets are in line with the marker corresponding to 34U.

Turning the screw in the counter-clockwise directionwill increase attenuation. These attenuators will typically come from the manufacturer with thescrew set for minimum attenuation.The fixed attenuators are not bidirectional, so care should be taken to ensure the properorientation of the input and output ports before fastening to the bracket. The input port shouldface towards the top of the frame, and the output port should face the ground.The following figure shows a high level view of the attenuator bracket locations on the TDMAframe (MCPA shelves not shown):

This information is considered to beCONFIDENTIAL and should be treated appropriately.The attenuator brackets should be mounted on the rear of the TDMA frame such that they are positioneddirectly behind the MCPA shelves allowing for the MCPA RF output cable to be routed through the cut awayarea in the brackets. The mounting ("U") locations for each bracket are shown below (referenced to top edge ofattenuator bracket):The above recommended "U" locations for the attenuator brackets assume the duplexer shelf was mounted at40U, the top MCPA shelf was mounted at 34U and the bottom MCPA shelf was mounted at 26U (see Figure7).If these recommended positions are not followed, the installer must at least ensure the attenuator bracket ismounted such that it allows clearance for the MCPA rack RF OUTPUT cable.

Each rack (or sector) must be calibratedindividually. The MCPA shelf interface software (NTFC07BC) version 1.5 should be executedand the user interface screen should look like the following:Figure: 13 Computer Screen for 2 Carrier CalibrationBefore beginning the initialization, the appropriate Com port for the computer MUST be selectedunder the “CommPort” pull down menu or the user interface software will shut down and theuser will experience run time errors. (See section 8.4.1 below).Because the TDMA MCPA shelves were originally designed for the Dual Mode Urban TDMACellsite product (at a lower power level), it is necessary to enter specific parameters in the fieldsof the user interface to prevent the MCPAs from being overdriven. When calibrating the MCPAshelf for 2 carriers at 47 dBm each, the following parameters should be entered on the userinterface screen. (This assumes that the levels going into the MCPA shelves have been set to 13dBm per carrier):Target output power per channel: enter “100”Number of channels: enter “1”

(again, this assumes that the level going into the MCPA shelf hasbeen set to 13 dBm):Computer Screen for 1 Carrier CalibrationTarget output power per channel: enter “50”Number of channels: enter “1” (same as 2 Carrier calibration)Potential Calibration ProblemsIf the calibration software reads “trying to connect to Nortel rack” at the bottom of the screen,the software cannot detect the MCPA rack, therefore do the following:ensure the com port used on the computer is the same as in the “CommPort” pull down menu onthe user interface screen.ensure the RS-232 interface cable is connected to the proper MCPA shelf connector “J6”.ensure the RS-232 interface cable is connected to the proper MCPA shelf.

This information is considered to beCONFIDENTIAL and should be treated appropriately.If the software sets the output power to the incorrect power level, do the following:Check that “Maximum Available Output Power” reads 120 Watts (this would indicate the rackrecognizes all 3 PA’s). If not, check that all 3 PA’s are enabled. If so, there may be a problemwith one of the PA’s.If a "Run-time error" occurs every time the user interface software is executed, do the following:Use the Windows Explorer to view the Windows directory.Double-click on the "REGEDIT.EXE" fileA Registry Editor will open.Double click on the directory "HKEY_CURRENT_USER"Double-click on the directory "SOFTWARE"Double-click on the directory "VB and VBA Program Settings"Double-click on the directory "Powerwave RD Testing"Double-click on the directory "System"In the file panel there is a file called "CommAlarmBoard," double-click on it.A dialog box will open and a "1" should be typed in the "value data:" entry box. This refers toComm 1. If there is already a 1, you might want to try 2,3 or 4.Choose "OK." The number "1" or the number you entered should be displayed in the datacolumn next to the CommAlarmBoard.Close the Registry Editor.Try executing the user interface software again.The reason you get this error is choosing a comm port that is not available. Verify that anotherprogram is not open and using the comm port that the user interface software is trying to use.TDMA Equipment List
