(See Figure 1 -1 UBS Macro BTSlow -tier/low -capacity frame (1000 mm rack) on page 1 - 27 and Figure 1 -2 Low capacity UBSMacro BTS starter frame (1800 mm rack) on page 1 - 28 .)T wo XMIs are equipped for the mid capacity UBS Macro frame. (See Figure 1 -3 UBS Macro BTSmid -capacity frame (1800 mm rack) on page 1 - 30 .)The XMI can support a UBS Macro frame in either an omni (1 -sector) or 3 -sector antennaconfiguration.An XMI in a UBS Macro frame can support the following quantity of carriers per sector:•F or the 800 MHz and 1.9 GHz RF bands, one XMI in a 3 -sector antenna configuration cansupport 4 carriers with reduced TX RF power output per sector -carrier and up to 3 carrierswith full TX RF power output per sector -carrier .•F or the 800 MHz RF band, 8 carriers per sector for an omni (1 -sector) antennaconfiguration.•F or the 1.9 GHz RF band, 5 carriers per sector for an omni (1 -sector) antenna configuration.The XMI transceiver uses receive diversity for each sector .F or transmit, the XMI transceiver typically provides 2 - 30 W transmit RF output power persector/carrier (120 W total available RF power , when measured at the output of the UBS Macroframe). In a 3 -sector antenna configuration, the maximum TX RF power per sector -carrier is20W .The XMI operates from +27 V DC input power .All external XMI I/O connections are made on the XMI front panel.7 -2 68P09283A64 -3FOA SEP 2007
1X UBS Macro B T S FRU XMI (T r ansceiv er Module Internal) ModuleThe XMI has the following items:•Main XMI processor/memory . This processor communicates with the XP AC , RX and TXcircuits, MMI and ENET (LMT) ports, and the controller in the DMI via the CPRI links.•Phase -locked loop (PLL) reference clock circuit that is synchronized to CPRI link serialdata input from the DMI. This clock reference signal is used to frequency synthesize allRX & TX local oscillators.•DC power distribution which includes a +27 V DC input bus bar with four automotive stylefuses. These fuses provide protected + 27 V DC branch circuits, one for each sector LP Aand one for the transceiver (TX/RX) PCB.•Heat sinks and cooling fans. The cooling fans in the fan tray mounted on the rear of theXMI draw air in from air vents on the XMI front panel through the XMI and exhausts airout the XMI rear panel.•Internal wiring for PCB interconnection.•Front panel with connectors for external equipment connections.68P09283A64 -3 7 -3FOA SEP 2007
XMI (T r ansceiv er Module Internal) Module Chapter 7: XMI R eplacement ProceduresRX Main & RX Diversity Signal HandlingIn the UBS Macro frame, the main RX antenna signal from each sector IDRF (IntegratedDuplexer RX Filter) is applied to the corresponding sector main RX RF input of XMI 1. Thisinput is applied to the main receiver path of the corresponding XMI 1 sector receiver .F or low capacity frames with one XMI, the diversity RX antenna signal from each sector IDRF isapplied to the corresponding sector diversity RX RF input of XMI 1. This input is applied to thediversity receiver path of the corresponding XMI 1 sector receiver .F or mid capacity frames with two XMIs, the main RX antenna signal from each sector IDRF isapplied to the corresponding sector main RX RF input of XMI 1. XMI 1 provides pre -amplifiedmain RX antenna signals at its RX EXP OUT connector . This connector connects to one of thefollowing:•optional RX splitter XMI 1 RX EXP IN connector . The RX splitter splits the main RXantenna signal and distributes it to the RX splitter XMI 2 RX EXP OUT connector . Thisconnector is cabled to XMI 2 RX EXP IN connector . This connection provides the mainreceiver path of the corresponding XMI 2 sector receiver .•optional XMI 1/XMI 2 RX cross -connect cable. This cable connects XMI 1 RX EXP OUTconnector to XMI 2 RX EXP IN connector . This connection provides the main receiver pathof the corresponding XMI 2 sector receiver .F or mid capacity frames with two XMIs, the diversity RX antenna signal from each sectorIDRF is applied to the corresponding sector diversity RX RF input of XMI 2. XMI 2 providespre -amplified diversity RX antenna signals at its RX EXP OUT connector . This connectorconnects to one of the following:•optional RX splitter XMI 2 RX EXP IN connector . The RX splitter splits the diversity RXantenna signal and distributes it to the RX splitter XMI 1 RX EXP OUT connector . Thisconnector is cabled to XMI 1 RX EXP IN connector . This connection provides the diversityreceiver path of the corresponding XMI 1 sector receiver .•optional XMI 1/XMI 2 RX cross -connect cable. This cable connects XMI 2 RX EXP OUTconnector to XMI 1 RX EXP IN connector . This connection provides the diversity receiverpath of the corresponding XMI 1 sector receiver .The XMI automatically detects whether the RX signals are coming directly from the IDRFsthrough the QMA cables or indirectly through the RX Expansion ports and adjusts its internalRX gain accordingly . This automatic detection and gain adjustment occurs only during anXMI power -up or reset.XMI RX Output Signal HandlingEach XMI sector main/diversity receiver detects the RF RX carriers for the correspondingsector . The detected main/diversity RX signals are A/D converted. These converted digitalsignals are applied to the RX baseband control array . This array selects the best main/diversityRX signals for the carriers assigned to the XMI.The RX baseband control array outputs the selected RX digital signals to the RXbaseband bus. The RX baseband bus is applied to the Serializer/De -serializer & DataMultiplexer/De -multiplexer . This stage multiplexes the RX baseband bus signals and convertsthem to a high -speed serial data signal. This multiplexed RX baseband serial data signal isapplied to the high -speed serial data interface which provides 1.2288 Gbps links to the HSLdata ports on the front panel of the XMI.7 -4 68P09283A64 -3FOA SEP 2007
1X UBS Macro B T S FRU XMI (T r ansceiv er Module Internal) ModuleXMI High -speed Serial data Links (HSL)The XMI has redundant 1.2288 Gbps high -speed serial data links, one link per HSL 1 and HSL 2data ports on the front panel of the XMI. These data ports, on the XMI, are connected to thehigh -speed serial data interface on the DMIs.The high -speed serial data link has a multiplexed serial data signal that contains RX/TXsector -carrier traffic and overhead data as well as any DMI/XMI communications data.TX Input Signal FlowThe multiplexed TX baseband serial data signal is applied, via the high -speed serial datainterface, to the input of the Serializer/De -serializer & Data Multiplexer/De -multiplexer . Thisstage demultiplexes and deserializes the TX baseband serial data signal into TX baseband I& Q output signals for each sector -carrier .Each sector -carrier TX baseband I & Q signal is applied to the TX baseband control array . Thisarray conditions and combines all of the TX I & Q signals and then selectively routes them to apair of quadrature signal outputs for the appropriate sector (i.e., one pair per sector).Each pair of quadrature signals is applied to the corresponding sector RF transmitter . Thequadrature signals are D/A converted and the resultant analog signal causes the sectortransmitter to output a low power multiplexed TX RF signal with the applicable FM modulated TXcarrier frequencies. This low power multi -carrier signal is referred to as the TX RF small signal.68P09283A64 -3 7 -5FOA SEP 2007
XMI (T r ansceiv er Module Internal) Module Chapter 7: XMI R eplacement ProceduresTX RF Small Signal HandlingF or 800 MHz XMIs, the TX RF small signal from each sector RF transmitter in the XMI isrouted to the TXD connector on the front panel of the XMI. When the TXD connector is properlyterminated, each sector TX RF path is completed and the TX RF small signal from each sectorRF transmitter in the XMI is applied to the 3 -sector TX RF input FTM. The FTM provides3 -sector TX RF output signals which drive the LP As.F or proper operation of the XMI TX RF outputs, the XMI TXD connector must beterminated with either a TXD attenuator or a TXD cable connected to a TX combiner .Currently the 800 MHz UBS Macro BTS frame do not support the use of a TXcombiner , but it will in the future. Therefore a TXD attenuator must be installed inthe TXD connector on all 800 MHz XMIs.F or 1.9 GHz XMIs, the TX RF small signal from each sector RF transmitter in the XMI is routeddirectly to the 3 -sector TX RF input FTM. The FTM provides 3 -sector TX RF output signalswhich drive the LP As.The 1.9 GHz XMIs do not have a TXD connector .In the future, the 1.9 GHz UBS Macro BTS frames will be equipped with 2:1 cavitycombiners that will connect to the TX output of the XMI LP As.TX RF Power AmplicationThe 3 -sector TX RF input FTM transforms the phase of each sector TX RF small signal. Each ofthese phase transformed input signals drives the corresponding sector TX RF LP A section.The sector TX RF LP A section amplifies the low power multi -carrier TX RF signal (i.e., TX RFsmall signal) to the final XMI TX RF power output for the sector . (Note that each XMI sector TXRF LP A section is capable of providing 30 W maximum TX RF power output). The final TX RFpower output signal of each sector TX RF LP A is applied to the 3 -sector TX RF output FTM.The output FTM transforms the phase of each sector final TX RF power output signal. Each ofthese phase transformed sector output signals is applied to a corresponding RF coaxial switchthat is relay actuated. Each RF coaxial switch routes the sector final TX RF power output signalto the corresponding sector TX RF output port (i.e., TX1, TX2 or TX3) on the XMI front panel.The open/closed state of each RF coaxial switch is controlled by its associated relay . When therelay is unenergized, its RF coaxial switch is open (N .O . = Normally Open). This conditionoccurs when the XMI looses DC power and may also occur under XP AC control.In the UBS Macro frame, the final TX RF power output signal from each sector of XMI 1 isrouted to the corresponding sector TX antenna via the corresponding sector IDRF .7 -6 68P09283A64 -3FOA SEP 2007
1X UBS Macro B T S FRU XMI (T r ansceiv er Module Internal) ModuleXPAC FunctionsThe XMI P A Controller (XP AC) communicates with the XMI processor and controls/monitorsthe following XMI circuits:•3 -sector TX RF output FTM.•Three multi -carrier TX RF LP A sections; one LP A section for each sector .•Five cooling fans in the fan tray mounted on the rear of the XMI.The XP AC and the XMI processor exchange control data and status/alarm messages via adedicated serial bus. The XP AC collects status/alarm inputs from each sector TX RF LP A, eachcooling fan and the TX RF output FTM. Then the XP AC reports this status/alarm information indata messages to the XMI processor .The output FTM detects forward/reverse power of each sector TX RF output and reports it tothe XP AC . If something like a sector antenna path with an extreme impedance mismatch causesabnormal detected forward/reverse power , the XP AC will signal the respective FTM RF coaxialswitch relay to open the switch and block the sector TX RF output signal.Each sector TX RF LP A has phase and power level sensors/controls throughout the LP A signalpath that the XP AC uses to dynamically increase/decrease the phase and power level of thesector TX RF output signal as needed.The XP AC monitors XMI and P A heatsink temperatures as well as the speed (T ACH) of each ofthe five cooling fans. The XP AC sends a Pulse -W idth Modulated (PWM) DC control signal toeach fan to increase/decrease fan speed as needed to provide proper cooling.System Impact/ConsiderationsP erforming this replacement procedure in a UBS Macro frame with one XMI willcause BTS downtime and suspend all BTS call processing.P erforming this replacement procedure in a UBS Macro frame with more than oneXMI will not cause BTS downtime, but will reduce BTS call processing capacity .In the UBS Macro frame with one XMI, removal of the XMI has the following effects:•Interrupts the Main and Diversity RX signal paths for all sectors.•Interrupts TX RF output power on all sectors.In the UBS Macro frame with more than one XMI: If XMI 1 is removed, the Main RX signal pathis interrupted for all sectors. If XMI 2 is removed, the Diversity RX signal path is interruptedfor all sectors.68P09283A64 -3 7 -7FOA SEP 2007

XMI F an T r a y Assembly Chapter 7: XMI R eplacement ProceduresXMI Fan Tray Assembly■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■XMI Fan Tray Assembly DescriptionThe XMI fan tray assembly consists of five 27 V DC fans mounted in a housing. This housing isthe removable rear panel of the XMI. (See Figure 7 -4 and Figure 7 -5 .)The fan tray assembly mounted on the rear of the XMI draws cooling air in from air vents on theXMI front panel through the XMI and exhausts air out the XMI rear panel.The XMI fan housing contains five fan mounting locations. Each fan mounting location has thefollowing:•built -in fan grille/finger -guard•four vibration isolator fan mounting posts•fan connector bracketEach individual fan has a electrical wiring and connector . The connector mounts in thecorresponding fan connector bracket.The XMI fan tray assembly is attached to the rear of the XMI and secured with four screws.When the XMI fan tray assembly is attached to the rear of the XMI, the five fan connectors matewith connectors on the XMI F an Interconnect Board (FIB).The XMI FIB provides a DC voltage connection to each fan in the fan tray assembly and is aconduit for fan speed information and control.The XMI P A Controller (XP AC) provides central control of the three LP A sections. In addition,the XP AC gathers LP A alarms and provides XMI fan speed control.System Impact/ConsiderationsTypically the XMI fan tray assembly replacement requires that the affected XMI be physicallyremoved from the UBS Macro BTS frame. However , if the rear of the frame is accessible, the XMIfan tray assembly can be replaced without physically removing the affected XMI from the frame.P erforming this replacement procedure on a frame with only one XMI will cause BTSdowntime and suspend call processing.If the frame is equipped with only one XMI, BTS service will be interrupted during the XMI fantray assembly replacement. If the frame is equipped with more than one XMI, only the affectedXMI will be out -of -service and the BTS will remain in service.Alarms will be reported during the replacement procedure.7 -22 68P09283A64 -3FOA SEP 2007

A secondDMI is optional. The DMIs are located in the right side of the XMI shelf in the UBS Macro BTSframe (see Figure 1 -1 UBS Macro BTS low -tier/low -capacity frame (1000 mm rack) on page1 - 27 ,Figure 1 -2 Low capacity UBS Macro BTS starter frame (1800 mm rack) on page 1 - 28 andFigure 1 -3 UBS Macro BTS mid -capacity frame (1800 mm rack) on page 1 - 30 ). The DMIs arestacked vertically in an XMI shelf slot. DMI 1 is on the top and DMI 2 is on bottom. If theoptional second DMI is not equipped, an empty DMI outer housing is in the DMI 2 position.The DMI includes a DMI assembly that slides into a DMI outer housing. The DMI assemblyconsists of a chassis with a controller board, two rear mounted cooling fans and a front panel.The DMI assembly may also be equipped with up to two modem boards. When the UBS MacroBTS frame equipment is shipped from the factory the DMI assembly is equipped with at least onemodem board. A second modem board is optional and may be either factory or field installed.The DMI can be equipped with either 1X CDMA modem boards, EV -DO modem boards, or acombination of one 1X CDMA modem board and one EV -DO modem board.Each modem board mounts on opposite sides of the controller board. Modem board -to -controllerboard electrical connection is via a printed circuit board mounted High Density Mezzanine(HDMEZZ) type connector . Each modem board is secured to the DMI assembly chassis withseven screws that are captivated to the modem board.Figure 8 -1 Removing and installing Modem 1 on page 8 - 13 and Figure 8 -2 Removing andinstalling Modem 2 on page 8 - 14 show the locations of Modem 1 and Modem 2 within theDMI assembly .The following rules apply to modem board location within the DMI:•F or a DMI equipped with one 1X CDMA modem board, the 1X CDMA modemboard is always Modem 1 location•F or a DMI equipped with one EV -DO modem board, the EV -DO modem boardis always Modem 2 location•F or a DMI equipped with a combination of one 1X CDMA modem board and oneEV -DO modem board, the 1X CDMA modem board is always Modem 1 locationand the EV -DO modem board is always Modem 2 location68P09283A64 -3 8 -3FOA SEP 2007
DMI (Digital Module Internal) Assembly Chapter 8: DMI R eplacement ProceduresThe DMI assembly is the FRU (i.e., spare) that is used for DMI replacement. This assemblyincludes a chassis with a controller board, fans, front panel and two modem boards. Thisassembly does not include an outer housing. The DMI outer housing in the UBS Macro BTSframe is reused.The DMI FRU that is used for DMI replacement can be either of the following:•F actory built DMI assembly – consisting of a DMI chassis, controller board, fans, frontpanel and two modem boards (i.e., 1X CDMA, EV -DO , or a combination of both).•Field prepared DMI assembly – consisting of a DMI chassis, controller board, fans, frontpanel and up to two modem boards (i.e., 1X CDMA, EV -DO , or a combination of both)that are added to the assembly in the field.This chapter provides a procedure describing how to field prepare a DMI assembly , byinstalling up to two modems, so that it matches the configuration of the failed DMI.The DMI assemblies do not include an outer housing. The DMI outer housing in the UBS MacroBTS frame is reused.The typical DMI replacement scenario is as follows:1. Remove the failed DMI assembly from its outer housing in the UBS Macro BTS frame.2. Remove the replacement DMI assembly from its packaging and install it into the outerhousing in the UBS Macro BTS frame.3. Place the failed DMI assembly into the packaging that the replacement DMI came in.The DMI assembly FRU is used as a replacement for a DMI with an internal DMIcomponent failure (including controller board, modem board, fan, or front panelfailure). Although, a DMI with a modem board failure can just have the failed modemboard replaced. This is covered in the Modem Board section of this chapter .This chapter also provides a procedure describing how to dismantle a failed DMIassembly in the field. This procedure is used if it is desired to reclaim known goodFRUs from the failed DMI assembly . A fter dismantling the DMI assembly , the failedportion may be returned to Motorola for repair and the reclaimed known good FRUsmay be restocked.8 -4 68P09283A64 -3FOA SEP 2007

The RGPS headis typically mounted outside on a mast/pole. (See Figure 1 -18 RGPS Head Mounting Detailson page 1 - 50 .)The RGPS head contains a GPS Receiver (GPSR) and built -in GPS RF antenna.The RGPS head 12–pin Deutsch type MMP connector is cabled to the S SI RGPS connector . Thisconnection allows the S SI to supply DC power to the RGPS head. In addition, control/datasignals are exchanged between the UBS Macro BTS frame and RGPS head via this connection.The RGPS head successfully tracks and acquires GPS satellites. The RGPS head detects GPSRF signals and extracts a 1 Pulse P er Second (1PPS) timing signal. This 1PPS signal is appliedto the DMI controller via the S SI connector . The DMI controller contains an internal MediumStability Oscillator (MSO) that is synchronized to the 1PPS timing signal and locked to the GPStime base. If satellite tracking is lost or if the RGPS head fails, the MSO can maintain systemtiming for up to 8 hours.If the UBS Macro BTS frame is equipped with an optional Quartz High Stability Oscillator(QHSO) that is mounted to the rear of the S SI, the DMI controller selects the QHSO as thebackup synchronization source instead of the MSO . The QHSO can maintain system timingfor up to 24 hours.Motorola RGPS HeadsCurrently there are two Motorola RGPS heads that may be used with UBS Macro BTS equipment(see Figure 1 -19 RGPS Head Equipment on page 1 - 51 ). These are as follows:•A later version Motorola RGPS head is typically installed at a new UBS Macro BTS site.•An earlier version Motorola RGPS head already installed at and existing Motorola equippedBTS site that is being upgraded with UBS Macro BTS equipment.The installed RGPS cabling supports operation of either version RGPS head. However , the laterversion RGPS head requires that the cabling to the head be routed outside the RGPS mountingmast/pole while the earlier version RGPS head requires that the cabling to the head be routedthrough the RGPS mounting mast/pole.12 -2 68P09283A64 -3FOA SEP 2007
