Base Radio Volume 2QUAD Channel 900 MHz Base Radio OverviewEnhanced Base Transceiver System (EBTS)1-18 68P80801E35-E 16-June-06QUAD 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 1-10 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.

Volume 2 Base RadioQUAD Channel 900 MHz Base Radio OverviewEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 1-19After 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. 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 infor-mation 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.

Volume 2 Base Radio Controllers900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 2-33Host 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.Note At 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.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.
Base Radio Controllers Volume 2900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)2-34 68P80801E35-E 16-June-06■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. 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.
Volume 2 Base Radio Controllers900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 2-35The 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■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 compo-nents 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)
Base Radio Controllers Volume 2900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)2-36 68P80801E35-E 16-June-06Digital 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 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.
Volume 2 Base Radio Controllers900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 2-37The 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 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.
Base Radio Controllers Volume 2900 MHz QUAD Channel Base Radio ControllerEnhanced Base Transceiver System (EBTS)2-38 68P80801E35-E 16-June-06The 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.

Base Radio Exciter Volume 2QUAD Channel 900 MHz ExciterEnhanced Base Transceiver System (EBTS)4-14 68P80801E35-E 16-June-06Memory CircuitryThe memory circuitry is an EEPROM on the Controller portion of the Exciter/Controller module. The Controller performs memory read and write opera-tions over the parallel bus. The memory device stores the following data...■kit number■revision number■module specific scaling and correction factors■serial number■free form information (scratch pad)A/D Converter CircuitryAnalog signals from various areas throughout the Exciter board enter the A/D converter (A/DC). The A/DC converts these analog signals to digital form. Upon request of the BRC, A/DC output signals enter the BRC via SPI lines. 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.
Volume 2 Base Radio ExciterQUAD Channel 900 MHz ExciterEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 4-15Synthesizer 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.90.3 MHz Voltage Controlled Oscillator (VCO)The synthesizer within the Low Noise IC sets the 90.3 MHz 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 preamplified/modulated RF signal is input directly from the Exciter via the Base Radio backplane. The RF input signal is applied to the input of the Linear Driver Module (LDM). The RF feedback signal is fed back to the Exciter, where it is monitored for errors. The primary function of the DC/Metering Boards is to monitor proper operation of the PA. This information is forwarded to the Base Radio Controller (BRC) via the SPI bus. The alarms diagnostic points monitored by the BRC on the PA include the following:■Forward power■Reflected power■PA temperature sense■Fan SensorQUAD PA OnlyThe DC/Metering Board in the QUAD Radio serves the same function as it does in other radios. However, its circuitry is modified for compatibility with the QUAD Station.

The LDM consists of a two-stage cascaded Class AB amplifier, with the final stage in a parallel configuration. See Table 5-2 for the approximate input and output levels of the various LDMs. The LDM output is fed to the RF Splitter/DC Distribution Board via an Interconnect Board.900 QUAD PAThe 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 5-2 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 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 BoardThe 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 and provide PA Bias Enable (900 MHz QUAD only)

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 40W PA, the amplified signals are then combined on the LFM and sent directly to the RF Interconnect Board. In the 70W PA, the amplified signals are then combined on the LFM and sent directly to the Combiner Board.See Table 5-2 for the approximate total summed output powers of the various LFMs, before output losses.RF Interconnect Board 40W- 800 MHz PA OnlyThe 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 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 Module40- 800 MHz, 70W- 800 MHz PAsThis 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. 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.
Volume 2 Power AmplifierPA Theory of OperationEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E 5-13For 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 issues a cut-back command to the Exciter module if the monitored temperature is greater than 185° F (85° C).800 MHz QUAD and 900 MHz QUADThis 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.

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 calcu-lation is exceedingly out of tolerance, the BRC issues a shut-down command to the Exciter.The Thermistor that monitors the operating temperature of the 800 MHZ QUAD and 900 MHz QUAD PAs is located on the DC/Metering Board

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.DC Core Board (QUAD+2)The Core Board communicates with the other base radio modules as well as internal PA modules.

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 6-2 shows the QUAD Channel Power Supply with the cover removed.Figure 6-2 Quad Carrier Power Supply

Volume 2 Parts and SuppliersBattery System ConnectionsEnhanced Base Transceiver System (EBTS)16-June-06 68P80801E35-E A-13Battery System Connections 8The 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 A-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 A-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 A-3 Battery System Wire SizeLoop Length Wire size20 feet 4/0 (or 250 MCM)30 feet 350 MCM45 feet 500 MCM
