68P80801E35-A 9/1/2001 23EBTS System Manual - Vol 1 System Installation and TestingGeneral 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 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 Guidelines 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.

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

10 68P80801E35-A 9/1/2001Base Radio EBTS System Manual - Vol 2Generation 2 Single Channel 800 MHz Base Radio Overview Generation2 Single Channel BR Theory of OperationThe BR operates in conjunction with other site controllers and equipment that are properly terminated. The following description assumes such a conﬁguration. Figures 5 shows an overall block diagram of the BR.Power is applied to the DC Power input located on the 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 BR performs self-diagnostic tests to ensure the integrity of the unit. These tests are primarily conﬁned to the EBRC and include memory and Ethernet veriﬁcation routines. After the self-diagnostic tests are complete, the BR reports any alarm conditions present on any of its modules to the site controller via Ethernet. Alarm conditions may also be veriﬁed locally using service computer and the STATUS port located on the front of the EBRC.The software resident in Flash Memory on the EBRC registers the BR with the site controller via Ethernet. Once registered, the BR software is downloaded via resident FLASH- or Ethernet and is executed from RAM. Operating parameters for the BR are included in this download. This software allows the BR to perform call processing functions. The BR operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, provides an increased channel capacity ratio of as much as 6 to 1. Both the receive and transmit signals of the BR are divided into 6 individual time slots. Each receive slot has a corresponding transmit slot; this pair of slots comprises a logical RF channel. The BR uses diversity reception for increased coverage area and improved quality. The Receiver module within the BR contains up to three receivers. Two Receivers are used with two-branch diversity sites, and three Receivers are used with three-branch diversity sites. All Receivers within a given BR are programmed to the same receive frequency. The signals from each receiver are fed to the EBRC where a diversity combining algorithm is performed on the signals. The resultant signal is processed for error correction and then sent to the site controller via Ethernet with the appropriate control information regarding its destination.The transmit section of the BR is comprised of two separate FRUs, the Exciter and Power Ampliﬁer (PA). Several PA FRUs are available, covering different applications and power levels; these are individually discussed as applicable in later subsections.The Exciter processes the information to transmit from the EBRC in the proper modulation format. This low level signal is sent to the PA where it is ampliﬁed to the desired output power level. The PA is a continuous keyed linear ampliﬁer. A power control routine monitors the output power of the BR and adjusts it as necessary to maintain the proper output level.

68P80801E35-A 9/1/2001 11EBTS System Manual - Vol 2 Base Radio ControllersEnhanced Base Radio Controller background mode. 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

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 RXDSP operates 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 RXDSP accepts digitized signals from the TISIC device through the RxDSP parallel bus. The RXDSP supports a single carrier (single 3 branch receiver) digital data input. The RXDSP accesses its DSP program and signal-processing algorithms in 128k words of internal memory. The RXDSP communicates with the host bus on an 8-bit interface. Additionally, a serial control path connects the two RXDSPs and the TXDSP. The Synchronous Communications Interface (SCI) port facilitates this serial control path.

68P80801E35-A 9/1/2001 13EBTS System Manual - Vol 2 Base Radio ControllersEnhanced Base Radio Controller For initialization and control purposes, the RXDSP connects to the TISIC device.The TXDSP operates at an external clock speed of 16.8 MHz, provided by the EBRC local station reference. The TXDSP internal operating clock is 150MHz, produced by an internal Phase Lock Loop (PLL). The TXDSP sends one carrier of digitized signal to the TISIC to reformat the date before sending it to the exciter. The exciter converts the digital signal to analog. 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 the 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 from the modulated 5 MHz signal❐Outputs a 1 PPS signal and a windowed version of this signal for network timing alignment.❐Outputs a 2.1 MHz reference signal used by the Exciter and Receiver(s).❐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 RXDSP.)❐Provides a 4.8 MHz reference signal. This signal is used by the Exciter to clock data into the TRANLIN❐Accepts differential data from the Receiver(s) (Rx through Rx3) via the interface circuitry.❐Transmits serial control data to the Receiver(s) (Rx through Rx3) via the serial data bus.❐Accepts and formats differential data from the TXDSP for transmission to the Exciter via interface circuitry.❐Generates the Receiver SSI (RxSSI) frame sync interrupt for the RxDSP.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

14 68P80801E35-A 9/1/2001Base Radio Controllers EBTS System Manual - Vol 2Enhanced Base Radio Controller voltage to the VCO through an analog gate. The analog gate closes when three conditions coexist: (1) The 5 MHz tests stable. (2) The PLL IC is programmed. (3) Two PLL oscillator and reference signal output alignments occur. A loss in the 5MHz / 1PPS signal causes the control voltage enable switch to open. This complex PLL control allows the BR to maintain 16.5 MHz capability during short disconnects (of approximately one minute) of the 5 MHz / 1 PPS signal. (For example, during 5 MHz / 1 PPS cable maintenance work.)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, and TISIC. The TISIC divides the 16.8 MHz signal by seven, and outputs a 2.1 MHz signal. This output signal then becomes the 2.1 MHz reference for the Exciter and Receiver(s).Input PortsOne general-purpose input register provides for EBRC 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 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 EBRC 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, 5.1, 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.

68P80801E35-A 9/1/2001 9EBTS System Manual - Vol 2 Base Radio ExciterLow Noise 800 MHz Exciter LNODCT IC CircuitryThe LNODCT IC (Low Noise Offset Direct Conversion Transmit 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 LNODCT IC’s internal synthesizer. The LNODCT compares the reference signal with the outputs of Voltage Controlled Oscillators (VCOs). The LNODCT might sense that a VCO’s output is out of phase or off-frequency. If so, then the LNODCT sends correction pulses to the VCO. The pulses adjust VCO output, thereby matching phase and frequency with the reference. The LNODCT IC up-converts baseband data from the EBRC to the transmit frequency. The LNODCT IC also down-converts the Transmit signal from the Power Ampliﬁer to baseband data for cartesian feedback linearization.The EBRC uses the Serial Peripheral Interface (SPI) bus to communicate with the LNODCT IC. The SPI bus serves as a general purpose, bi-directional, serial link between the EBRC 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 970 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 970 MHz Voltage Controlled Oscillator (VCO) circuit. 970 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 970 MHz VCO output mixes with the 90.3 MHz VCO output. The result is a Local Oscillator [LO) signal for the LNODCT IC. The LNODCT uses this LO signal to up-convert the programmed transmit frequency. The LNODCT 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 LNODCT 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 LNODCT IC. The RF Ampliﬁer generates an appropriate signal level to drive the PA.

However, its circuitry is modiﬁed for compatibility with the QUAD Station. As a result, its logic circuitry is operated at 3.3 VDC.In addition to the functions listed for non-QUAD versions above, the following meter points are ported to the SPI bus:❐A and B Currents❐Thermistor (for PA temperature sensing circuit on the DC/Metering Board)Linear Driver Module40W-800 MHz, 70W-800 MHZ and 800 MHZ QUAD PAsThe Linear Driver Module (LDM) ampliﬁes the low-level RF signal from the Exciter.

The LDM consists of a three stage, cascaded, Class AB ampliﬁer, with the ﬁnal stage in a parallel conﬁguration. See Table 2 for the approximate input and output power of the 900 MHz QUAD LDM. The LDM Output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board.Interconnect Board (40W-800 MHz, 70W-800 MHz , 800 MHz QUAD and 900 MHz QUAD)The output of the LDM is applied to the Interconnect Board, which provides an RF connection to the RF Splitter/DC Distribution Board. As a separate function, area on the Interconnect Board serves as a convenient mounting location for electrolytic capacitors used for ﬁltering the +28 VDC supply. RF Splitter/DC Distribution Board40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUADThe RF Splitter portion of this board accepts the ampliﬁed signal from the LDM (via the Interconnect Board). The primary function of this circuit is to split the RF signal into drive signals for the LFMs. In the 40W-800 MHz PA, this circuit splits the drive signal into three separate paths to be applied to the three LFMs, where the signals will be ampliﬁed further. In the 70W-800 MHz, 800 MHz QUAD and 900 MHZ QUAD PAs, this circuit splits the drive signal into six separate paths to be applied to the six LFMs, where the signals will be ampliﬁed further.The DC Distribution portion of this board interfaces directly with the DC/Metering Board to route DC power to the LFMs. 900 MHz and 1500 MHzThe RF Splitter portion of this board accepts the ampliﬁed signal from the LDM. The primary function of this circuit is to split the RF signal into two separate paths. These two outputs are fed directly to two separate Linear Final modules where the RF signals will be ampliﬁed further. The DC Distribution portion of this board interfaces directly with the DC/Metering Board to route DC power to the LFMs. Linear Final Modules 40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUADThe RF Splitter output signals are applied directly into the LFMs for ﬁnal ampliﬁcation. Each LFM contains a coupler that splits the LFM input signal and feeds the parallel Class AB ampliﬁers that amplify the RF signals.

In the 70W PA, the ampliﬁed signals are then combined on the LFM and sent directly to the Combiner Board.See Table 2 for the approximate total summed output powers of the various LFMs, before output losses.900 MHz PAThe RF signals from the outputs of the RF Splitter are applied directly into the Linear Final Module (LFM) for ﬁnal ampliﬁcation. Each LFM contains a branchline coupler that splits the LFM’s input signal and feeds the dual Class AB push-pull ampliﬁers that amplify the RF signals. The ampliﬁed signals are then combined on the LFM and sent directly to the RF Combiner circuit for ﬁnal distribution. See Table 2 for the approximate total summed output power of the 900 MHz LFMs, before output losses.1500 MHz PAThe two RF signals from the outputs of the RF Splitter are input directly into the Linear Final Module (LFM) for ﬁnal ampliﬁcation. Each LFM contains a branchline coupler that splits the LFM’s input signal and feeds the dual Class AB push-pull ampliﬁers that amplify the RF signals. The ampliﬁed signals are then combined on the LFM , via a branchline coupler, and sent directly to the RF Combiner circuit for ﬁnal distribution. See Table 2 for the approximate total summed output power of the 1500 MHz LFMs, before output losses.The current drains of the 1500 MHz LFMs are monitored by the A/D converter on the DC/Metering board. A voltage signal representative of the LFM current drain is sent to the BRC. A Power Ampliﬁer alarm is generated if the signal is outside of either the upper or lower limits.RF Interconnect Board (40W- 800 MHz PA Only)The RF Interconnect Board consists of transmission line paths which route the three output signals from the LFMs to the three inputs of the RF Combiner/Peripheral Module.Combiner Board (40W- 800 MHz, 70W- 800 MHz, 800 MHz QUAD and 900 MHz QUAD PAs)The Combiner Board combines pairs of signals into single signals, thereby combining the six signals from the LDMs into three signals. The resulting three signals are applied to the RF Combiner/Peripheral Module.RF Combiner/Peripheral Module (40- 800 MHz, 70W- 800 MHz PAs)This module consists of two portions: an RF combiner and a peripheral module. 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.

68P80801E35-A 9/1/2001 13EBTS System Manual - Vol 2 Power Amplifier (PA)PA Theory of Operation 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.

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 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.

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.

10 68P80801E35-A 9/1/2001Parts 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
