14 68P80801H45-1 1/20/2002Base Radios EBTS System Manual - Vol 2General Safety Information Human Exposure ComplianceThis equipment is designed to generate and radiate radio frequency (RF) energy by means of an external antenna. When terminated into a non-radiating RF load, the base station equipment is certified to comply with Federal Communications Commission (FCC) regulations pertaining to human exposure to RF radiation in accordance with the FCC Rules Part 1 section 1.1310 as published in title 47 code of federal regulations and procedures established in TIA/EIA TSB92, Report on EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines, Compliance to FCC regulations of the final installation should be assessed and take into account site specific characteristics such as type and location of antennas, as well as site accessibility of occupational personnel (controlled environment) and the general public (uncontrolled environment). This equipment should only be installed and maintained by trained technicians. Licensees of the FCC using this equipment are responsible for insuring that its installation and operation comply with FCC regulations Part 1 section 1.1310 as published in title 47 code of federal regulations.Whether a given installation meets FCC limits for human exposure to radio frequency radiation may depend not only on this equipment but also on whether the “environments” being assessed are being affected by radio frequency fields from other equipment, the effects of which may add to the level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating facilities that exist at the time of the licensee’s equipment is being installed or even by equipment installed later. Therefore, the effects of any such facilities must be considered in site selection and in determining whether a particular installation meets the FCC requirements.FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter sites of various complexities may be accomplished by means of computational methods. For more complex sites direct measurement of power density may be more expedient. Additional information on the topic of electromagnetic exposure is contained in the Motorola Standards and Guideline for Communications Sites publication. Persons responsible for installation of this equipment are urged to consult the listed reference material to assist in determining whether a given installation complies with the applicable limits.In general the following guidelines should be observed when working in or around radio transmitter sites:- All personnel should have electromagnetic energy awareness training.- All personnel entering the site must be authorized.- Obey all posted signs- Assume all antennas are active- Before working on antennas, notify owners and disable appropriate transmitters.- Maintain minimum 3 feet clearance from all antennas.- Do not stop in front of antennas.- Use personal RF monitors while working near antennas.- Never operate transmitters without shields during normal operation.- Do not operate base station antennas in equipment rooms

14 68P80801H45-1 1/20/2002Base Radio EBTS System Manual - Vol 2QUAD Channel 900 MHz Base Radio Overview QUAD Channel 900 MHz Base Radio Theory of OperationThe QUAD Channel 900 MHz BR operates with other site controllers and equipment and must be properly terminated. The following description assumes such a configuration. Figure 6 show an overall block diagram of the QUAD Channel 900 MHz BR.Power is applied to the DC Power inputs located on the QUAD Channel 900 MHz BR backplane. The DC Power input is connected if -48 VDC or batteries are used in the site.Power is applied to the BR by setting the Power Supply power switch to the ON position. Upon power-up, the QUAD Channel 900 MHz BR performs self-diagnostic tests to ensure the integrity of the unit. These tests, which include memory and Ethernet verification routines, primarily examine the EX / CNTL. After completing self-diagnostic tests, the QUAD Channel 900 MHz BR reports alarm conditions on any of its modules to the site controller via Ethernet. Alarm conditions may also be verified locally. Local verification involves using the service computer and the STATUS port located on the front of the QUAD Channel 900 MHz EX / CNTL.The software resident in FLASH on the EX / CNTL registers the BR with the site controller via Ethernet. After BR registration on initial power-up, the BR software downloads via resident FLASH or Ethernet and executes from RAM. The download includes operating parameters for the QUAD Channel 900 MHz BR. These parameters allow the QUAD Channel 900 MHz BR to perform call processing functions. After software downloads to the BR via Ethernet, FLASH memory stores the software object. Upon future power-ups, the software object in FLASH loads into RAM for execution.The BR operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, increases channel capacity by a ratio of as much as six to one. TDMA divides both the receive and transmit signals of the BR into six individual time slots. Each receive slot has a corresponding transmit slot. This pair of slots comprises a logical RF channel.
68P80801H45-1 1/20/2002 15EBTS System Manual - Vol 2 Base RadioQUAD Channel 900 MHz Base Radio Overview The BR uses diversity reception for increased coverage area and improved quality. The Receiver modules within the QUAD Channel 900 MHz BR contain three receiver paths. Two-branch diversity sites use two Receiver paths, and three-branch diversity sites use three Receiver paths. All Receiver paths within a given Receiver module are programmed to the same receive frequency. Signals from each receiver arrive at the EX / CNTL module. This module performs a diversity combining algorithm on the signals. The resultant signal undergoes an error-correction process. Then, via Ethernet, the site controller acquires the signal, along with control information about signal destination.Two separate FRUs comprise the transmit section of the QUAD Channel 900 MHz BR. These are the Exciter portion of the EX / CNTL and the Power Amplifier (PA). The Exciter processes commands from the CNTL, assuring transmission in the proper modulation format. Then the low-level signal enters the PA. The PA amplifies this signal to the desired output power level. The PA is a continuously keyed linear amplifier. A power control routine monitors the output power of the BR. The routine adjusts the power as necessary to maintain the proper output level.

Figure 13 is a functional block diagram of the BRC. Host MicroprocessorThe host microprocessor is the main controller for the BR. The processor operates at a 50-MHz clock speed. The processor controls Base Radio operation according to station software in memory. Station software resides in FLASH memory. For normal operation, the system transfers this software to non-volatile memory. An EEPROM contains the station codeplug.NOTEAt BR power-up, the EXBRC LED indicates a major alarm. This indication continues until BR software achieves a predetermined state of operation. Afterward, the software turns off the EXBRC LED.Table 8 900 MHz QUAD Channel BR Controller Controls Control DescriptionRESET Switch A push-button switch used to manually reset the BR.STATUS connectorA 9-pin connector used for connection of a service computer, providing a convenient means for testing and configuring.Table 9 Pin-outs for the STATUS ConnectorPin-out Signal1 not used2 TXD3 RXD4 not used5 GND6 not used7 not used8 not used9 not used

20 68P80801H45-1 1/20/2002Base Radio Controllers EBTS System Manual - Vol 2900 MHz QUAD Channel Base Radio Controller Serial Communication BusesThe microprocessor provides a general-purpose SMC serial management controller bus.The SMC serial communications bus is an asynchronous RS-232 interface with no hardware handshake capability. The BRC front panel includes a nine-pin, D-type connector. This connector provides a port where service personnel may connect a service computer. Service personnel can perform programming and maintenance tasks via Man-Machine Interface (MMI) commands. The interface between the SMC port and the front- panel STATUS connector is via EIA-232 Bus Receivers and Drivers.Host ProcessorThe microprocessor incorporates 4k bytes of instruction cache and 4k bytes of data cache that significantly enhance processor performance.The microprocessor has a 32-line address bus. The processor uses this bus to access non-volatile memory and SDRAM memory. Via memory mapping, the processor also uses this bus to control other BRC circuitry. The microprocessor uses its Chip Select capability to decode addresses and assert an output signal. The eight chip-select signals select non-volatile memory, SDRAM memory, input ports, output ports, and DSPs.The Host processor... ❐Provides serial communications between the Host Microprocessor and other Base Radio modules.❐Provides condition signals necessary to access SDRAM.❐Accepts interrupt signals from BRC circuits (such as DSPs). ❐Organizes the interrupts, based on hardware-defined priority ranking.❐The Host supports several internal interrupts from its Communications Processor Module. These interrupts allow efficient use of peripheral interfaces.❐The Host supports 10 Mbps Ethernet/IEEE 802.3. ❐Provides a 32-line data bus transfers data to and from BRC SDRAM and other BRC circuitry. Buffers on this data bus allow transfers to and from non-volatile memory, general input and output ports and DSPs.Non-Volatile MemoryBase Radio software resides in 2M x 32 bits of FLASH memory. The Host Microprocessor addresses the FLASH memory with 20 of the host address bus’ 32 lines. The host accesses FLASH data over the 32-line host data bus. A host-operated chip-select line provides control signals for these transactions. The FLASH contains the operating system and application code. The system stores application code in FLASH for fast recovery from reset conditions. Application code transfers from network or site controllers may occur in a

Background mode transfers allow the station to remain operational during new code upgrades.The data that determines the station personality resides in a 32K x eight bit codeplug EEPROM. The microprocessor addresses the EEPROM with 15 of the host address bus’ 32 lines. The host accesses EEPROM data with eight of the data bus’ 32 lines. A host-operated chip-select line provides control signals for these transactions. During the manufacturing process, the factory programs the codeplug’s default data. The BRC must download field programming data from network and site controllers. This data includes operating frequencies and output power level. The station permits adjustment of many station parameters, but the station does not store these adjustments. Refer to the Software Commands chapter for additional information.Volatile MemoryEach BRC contains 8MB x 32 bits of SDRAM. The BRC downloads station software code into SDRAM for station use. SDRAM also provides short-term storage for data generated and required during normal operation. SDRAM is volatile memory. A loss of power or system reset destroys SDRAM data. The system performs read and write operations over the Host Address and Data buses. These operations involve column and row select lines under control of the Host processor’s DRAM controller. The Host address bus and column row signals sequentially refresh SDRAM memory locations.Ethernet InterfaceThe Host processor’s Communications Processor Module (CPM) provides the Local Area Network (LAN) Controller for the Ethernet Interface. The LAN function implements the CSMA/CD access method, which supports the IEEE 802.3 10Base2 standard. The LAN coprocessor supports all IEEE 802.3 Medium Access Control, including the following: ❐framing ❐preamble generation ❐stripping❐source address generation❐destination address checkingThe PCM LAN receives commands from the CPU. The Ethernet Serial Interface works directly with the CPM LAN to perform the following major functions:❐10 MHz transmit clock generation (obtained by dividing the 20 MHz signal provided by on-board crystal)❐Manchester encoding/decoding of frames
22 68P80801H45-1 1/20/2002Base Radio Controllers EBTS System Manual - Vol 2900 MHz QUAD Channel Base Radio Controller ❐electrical interface to the Ethernet transceiverAn isolation transformer provides high-voltage protection. The transformer also isolates the Ethernet Serial Interface (ESI) and the transceiver. The pulse transformer has the following characteristics:❐Minimum inductance of 75 µH❐2000 V isolation between primary and secondary windings❐1:1 Pulse Transformer The Coaxial Transceiver Interface (CTI) is a coaxial cable line driver and receiver for the Ethernet. CTI provides a 10Base2 connection via a coaxial connector on the board. This device minimizes the number of external components necessary for Ethernet operations. A DC/DC converter provides a constant voltage of -9 Vdc for the CTI from a 3.3 Vdc source. The CTI performs the following functions:❐Receives and transmits data to the Ethernet coaxial connection❐Reports any collision that it detects on the coaxial connection❐Disables the transmitter when packets are longer than the legal length (Jabber Timer)Digital Signal ProcessorsThe BRC includes two Receive Digital Signal Processors (RXDSPs) and a Transmit Digital Signal Processor (TXDSP). These DSPs and related circuitry process compressed station transmit and receive audio or data. The related circuitry includes the TDMA Infrastructure Support IC (TISIC) and the TISIC Interface Circuitry. The DSPs only accept input and output signals in digitized form.The RXDSP inputs are digitized receiver signals. The TXDSP outputs are digitized voice audio and data (modulation signals). These signals pass from the DSP to the Exciter portion of the EXBRC. DSPs communicate with the Microprocessor via an eight-bit, host data bus on the host processor side. For all DSPs, interrupts drive communication with the host.The RXDSPs operate from an external 16.8 MHz clock, provided by the local station reference. The RXDSP internal operating clock signal is 150MHz, produced by an internal Phase-Locked Loop (PLL). The RXDSPs accept digitized signals from the receivers through Enhanced Synchronous Serial Interface (ESSI) ports. Each of two ESSI ports on a RXDSP supports a single carrier (single receiver) digital data input. The DSP circuitry includes two RXDSPs. These allow processing of up to four carriers (four receivers).The RXDSP accesses its DSP program and signal-processing algorithms in 128k words of internal memory. The RXDSPs communicate with the host bus over an 8-bit interface. Each RXDSP provides serial communications to its respective receiver module for receiver control via a Serial Peripheral Interface (SPI). The SPI is a
68P80801H45-1 1/20/2002 23EBTS System Manual - Vol 2 Base Radio Controllers900 MHz QUAD Channel Base Radio Controller parallel-to-serial conversion circuit, connected to the RXDSP data bus. Each RXDSP communicates to two receive modules through this interface.Additionally, a serial control path connects the two RXDSPs and the TXDSP. The Synchronous Communications Interface (SCI) port facilitates this serial control path. For initialization and control purposes, one RXDSP connects to the TISIC device.The TXDSP operates at an external clock speed of 16.8 MHz, provided by the EXBRC local station reference. The TXDSP internal operating clock is 150MHz, produced by an internal Phase Lock Loop (PLL). The TXDSP sends up to four carriers of digitized signal to the EX11 exciter. The exciter converts the digital signal to analog. Also at the exciter, a highly stable clock reclocks the digital data. Reclocking enhances transmit signal integrity. Two framed and synchronized data streams result. One data stream is I-data, and the other is the Q-data stream.The TXDSP contains its own, internal address and data memory. The TXDSP can store 128k words of DSP program and data memory. An eight-bit interface handles TXDSP-to-host bus communications.TISICThe TISIC controls internal DSP operations. This circuit provides the following functions:❐For initialization and control, interfaces with one RXDSP via the DSP address and data buses.❐Accepts a 16.8 MHz signal from Station Reference Circuitry.❐Accepts a 5 MHz signal, modulated with one pulse per second (1 PPS) from the site reference. ❐Demodulates the 1 PPS ❐Outputs a 1 PPS signal and a windowed version of this signal for network timing alignment.❐Outputs a 2.4 MHz reference signal used by the Exciter.❐Generates 15 ms and 7.5 ms ticks. (These ticks synchronize to the 1 PPS time mark. The system decodes the time mark from the site reference. Then the system routes the reference to the TXDSP and RXDSPs.)Station Reference CircuitryThe Station Reference Circuitry is a phase-locked loop (PLL). This PLL consists of a high-stability, Voltage-Controlled, Crystal Oscillator (VCXO) and a PLL IC. GPS output from the iSC connects to the 5 MHz/1 PPS BNC connector on the BR backplane. Wiring at this connector routes signals to EXBRC station reference circuitry. The PLL compares the 5 MHz reference frequency to the 16.8 MHz VCXO output. Then the PLL generates a DC correction voltage. The PLL applies this correction voltage to the VCO through an analog gate. The analog gate closes when three
24 68P80801H45-1 1/20/2002Base Radio Controllers EBTS System Manual - Vol 2900 MHz QUAD Channel Base Radio Controller conditions coexist: (1) The 5 MHz tests stable. (2) The PLL IC is programmed. (3) Two PLL oscillator and reference signal output alignments occur. When the gate enables, the control voltage from the PLL can adjust the high-stability VCXO frequency. The adjustment can achieve a stability nearly equivalent to that of the external, 5 MHz frequency reference.The correction voltage from the PLL continuously adjusts the VXCO frequency. The VXCO outputs a 16.8 MHz clock signal. The circuit applies this clock signal to the receiver, 48 MHz reference and TISIC. The receivers use the 16.8MHz as the clock input and synthesizer reference.The 48 MHz EXBRC synthesizer uses the 16.8 MHz as its synthesizer reference. The 48 MHz synthesizer output is the clock input for the TXDSP I and Q data reclock circuitry.The TISIC divides the 16.8 MHz signal by seven, and outputs a 2.4 MHz signal. This output signal then becomes the 2.4 MHz reference for the Exciter.Input PortsOne general-purpose input register provides for BRC and station circuit input signals. The register has 16 input ports. The Host Data Bus conveys input register data to the Host Microprocessor. Typical inputs include 16.8 and 48 MHz Station Reference Circuitry status outputs and reset status outputs.Output PortsTwo general-purpose output registers distribute control signals from the Host Microprocessor to the BRC and station circuitry. One register has 32 output ports and the other register has 8 output ports. Control signal distribution occurs over the backplane. The Host Data Bus drives the output ports’ latched outputs. Typical control signals include front-panel LED signals and SPI peripheral enable and address lines.Remote Station ShutdownThe BRC contains power supply shutdown circuitry. This circuitry can send a shutdown pulse to the Base Radio Power Supply. BRC software generates the shutdown control pulse. After receiving a shutdown pulse, the power supply turns off BR power. Shut down power sources include 3.3, 28.6 and 14.2 Vdc sources throughout the BR. Due to charges retained by BR storage elements, power supply voltages may not reach zero. The shutdown only assures that the host processor enters a power-on-reset state. A remote site uses the shutdown function to perform a hard reset of all BR modules.

The Controller periodically monitors all signals.Some of the monitored signals include amplifier bias and synthesizer signals. Low Noise Offset Direct Conversion Transmit (LNODCT) IC CircuitryThe Low Noise IC is a main interface between the Exciter and BRC. The BRC’s Digital Signal Processor (DSP) sends digitized signals (baseband data) to the Exciter over the DSP data bus.The differential data clock signal serves as a 2.4 MHz reference signal to the Low Noise IC’s internal synthesizer. The Low Noise IC compares the reference signal with the outputs of Voltage Controlled Oscillators (VCOs). The Low Noise IC might sense that a VCO’s output is out of phase or off-frequency. If so, then the Low Noise IC sends correction pulses to the VCO. The pulses adjust VCO output, thereby matching phase and frequency with the reference. The Low Noise IC up-converts baseband data from the BRC to the transmit frequency. The Low Noise IC also down-converts the Transmit signal from the Power Amplifier to baseband data for cartesian feedback linearization.The BRC uses the Serial Peripheral Interface (SPI) bus to communicate with the Low Noise IC. The SPI bus serves as a general purpose, bi-directional, serial link between the BRC and other Base Radio modules, including the Exciter. The SPI carries control and operational data signals to and from Exciter circuits.Synthesizer CircuitryThe synthesizer circuit consists of the Phase-Locked Loop (PLL) IC and associated circuitry. This circuit’s controls the 1025 MHz VCO signal. An internal phase detector generates a logic pulse. This pulse is proportional to the phase or frequency difference between the reference frequency and loop pulse signal. The charge pump circuit generates a correction signal. The correction signal moves up or down in response to phase detector output pulses. The correction signal passes through the low-pass loop filter. The signal then enters the 1025 MHz Voltage Controlled Oscillator (VCO) circuit. 1025 MHz Voltage Controlled Oscillator (VCO)For proper operation, the VCO requires a very low-noise, DC supply voltage. An ultra low-pass filter prepares the necessary low-noise voltage and drives the oscillator. A portion of the oscillator output signal enters the synthesizer circuitry. The circuitry uses this feedback signal to generate correction pulses. The 1025MHz VCO output mixes with the 90.3 MHz VCO output. The result is a Local Oscillator [LO) signal for the Low Noise IC. The LNODCT uses this LO signal to up-convert the programmed transmit frequency. The Low Noise IC also uses the LO signal to down-convert the PA feedback signal.

The 90.3 MHz VCO provides a LO signal to the LNODCT IC. The Low Noise IC uses this signal in up-converting and down-converting the feedback signal. Regulator CircuitryThe voltage regulators generate three regulated voltages: +3 Vdc, +5 Vdc and +11.7 Vdc. The regulators obtain input voltages from the +3.3 Vdc and +14.2 Vdc backplane voltages. The regulated voltages power various ICs and RF devices in the Exciter.Linear RF Amplifier StagesThe linear RF amplifiers boost the RF signal from the Low Noise IC. The RF Amplifier generates an appropriate signal level to drive the PA.

The RF Combiner portion of the module combines the three RF signals from the RF Interconnect Board (40W- 800 MHz PA) or the Combiner Board (70W- 800 MHz PA) into a single signal using a Wilkinson coupler arrangement. Following the combiner circuit, the single combined RF signal is then passed through a directional coupler which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a single stage circulator, which protects the PA in the event of high reflected power. The peripheral portion of the module provides a power monitor circuit that monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required.Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter.A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the PA. The thermistor signal indicating excessive temperature is applied to the A/D converter and then sent to the BRC. The BRC rolls back forward power if the monitored temperature is excessive.900 MHz PAThis module consists of two parts: an RF combiner and a peripheral module. The RF combiner combines the two RF signals from each LDM into a single signal, using a branchline coupler arrangement. Then, the RF signal passes through a directional coupler which derives a signal sample of the LFMs RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal, thereby allowing the Exciter to accordingly adjust signal drive. Following the coupler, the power output signal is passed through a circulator, which protects the PA in the event of high reflected power. A power monitor circuit monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required.

A voltage representative of the monitored temperature is sent from the A/D converter to the BRC. The BRC rolls back forward power if the monitored temperature is excessive.1500 MHzBoth LFM outputs are input into this module where they are combined, with a branchline coupler, for a single output signal. The RF signal is first coupled to the Exciter module, via the DC/Metering Board, so that it can be monitored. The RF output signal is then passed through a circulator that acts as a protection device for the PA in the event of reflected power. A power monitor circuit monitors the forward and reflected power of the output signal. This circuit provides the A/D converter on the DC/Metering board with an input signal representative of the forward or reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC module via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. The programmed forward power is set through the use of MMI commands. If the level is not within certain parameters, the BRC will issue a warning to the site controller and may shut-down the Exciter module.Reflected power is monitored in the same manner except that the BRC determines an acceptable reflected power level. The BRC calculates the reflected power through an algorithm stored in memory. If the reflected power is determined to be excessive, the forward power is rolled back. If the reflected power level is extremely excessive, the BRC will issues a shut-down command to the Exciter module.A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the Power Amplifier. A voltage representative of the monitored temperature is sent from the A/D converter to the BRC. The BRC issues a cut-back command to the Exciter module if the monitored temperature is greater than 121˚ F (85˚ C).RF Combiner/Peripheral Module (800 MHz QUAD and 900 MHz QUAD)This module consists of two parts: an RF combiner and a Peripheral module. The RF combiner combines three RF signals from the Combiner Board into a single signal using a Wilkinson coupler arrangement. Following the combiner circuit, the single combined RF signal is then passed through a directional coupler, which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a dual stage circulator, which protects the PA in the event of high reflected power.
16 68P80801H45-1 1/20/2002Power Amplifier (PA) EBTS System Manual - Vol 2PA Theory of Operation The Peripheral module provides a power monitor circuit that monitors the forward and reflected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals, representative of the forward and reflected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within tolerance, the BRC will issue a warning to the site controller, which, in turn, will shut down the Exciter, if required.Reflected power is monitored in the same manner. The BRC uses the reflected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is calculated as excessive, forward power is rolled back. If the VSWR calculation is exceedingly out of tolerance, the BRC issues a shut-down command to the Exciter.NOTEThe Thermistor that monitors the operating temperature of the 800 MHZ QUAD and 900 MHz QUAD PAs is located on the DC/Metering BoardFan ModuleThe PA contains a fan assembly to maintain normal operating temperature through the use of a cool air intake. The fan assembly consists of three individual fans in which airflow is directed across the PA heatsink. The current draw of the fans is monitored by the DC/Metering Board. A voltage representative of the current draw is monitored by the BRC. The BRC flags the iSC if an alarm is triggered. The PA LED on the front panel of the BRC also lights, however the PA does not shut down due to a fan failure alone.

68P80801H45-1 1/20/2002 5EBTS System Manual - Vol 2 DC Power SupplyDC Power Supply for QUAD Channel Base Radios DC Power Supply for QUAD Channel Base RadiosQUAD Channel DC Power Supply OverviewThe QUAD Channel DC Power Supply provides DC operating voltages to QUAD Channel Base Radio FRUs. The power supply accepts input voltage sources from 41VDC to 60VDC. Input sources may be either positively or negatively grounded.On initial startup, the supply requires a nominal 43 VDC. If the voltage drops below 41 VDC, the QUAD Channel DC Power Supply enters quiescent mode. In quiescent mode, the power supply emits no power.The QUAD Channel DC Power Supply is designed for sites with an available DC voltage source. Output voltages from the DC Power Supply are 28.6 VDC, 14.2 VDC and 3.3 VDC, with reference to output ground. The supply is rated for 575 Watts of continuous output, with up to 113˚ F (45˚ C) inlet air. At 140˚ F (60˚ C), the 28.6 VDC output reduces to 80% of maximum. The QUAD Channel DC Power Supply consists of the Power Supply and front panel hardware. The QUAD Channel DC Power Supply connects to the chassis backplane through an edgecard connector. Two Torx screws on the front panel secure the QUAD Channel DC power supply to the chassis.Figure 2 shows the QUAD Channel Power Supply with the cover removed.Figure 2 Quad Carrier Power Supply

10 68P80801H45-1 1/20/2002Parts and Suppliers EBTS System Manual - Vol 2 Battery System ConnectionsThe cable loop length refers to the total length of wire within a given circuit. For example, the combined length of the -48 Vdc (hot) lead and the DC return lead equals the cable loop length. This would mean that a cabinet that needs 16 feet of wire between the batteries and Power Supply Rack has a total loop length of 32 feet.Determining Battery System Wire SizeThe wire size for the connection between the batteries and the Power Supply Rack is determined by the required wire length and the maximum allowable voltage drop. The voltage drop in the loop must be kept to below 200 mV. The wire selected should be UL approved and contain a high number of strands for flexibility.For a standard configuration, the Power Supply rack is located directly adjacent to the batteries with a cable loop length of 20 feet or less, which requires the use of a 4/0 wire. Table 3 shows recommended wire sizes for various loop lengths. Larger wire sizes may be used if the recommended sizes are not available. The recommended wire sizes are large enough to allow site expansion to a fully loaded site.Selecting Battery System LugsDepending on the wire size used and the manufacturer of the Batteries, different wire lugs are crimped onto the power cable ends. After the wire size has been determined from Table 3, verify the manufacturer of the Batteries (Dynasty or Absolyte). Two different battery systems are offered with the EBTS. The Dynasty system is a low to medium capacity, field expandable system supplied for smaller sites or sites with minimal backup hour requirements. This system is custom designed to Motorola specifications. The Dynasty system is manufactured by Johnson Controls:Table 3 Battery System Wire SizeLoop Length Wire size20 feet 4/0 (or 250 MCM)30 feet 350 MCM45 feet 500 MCM
