St. Louis, MO 4. System Functional Description The OPAF-1923-P07C01 is an AC powered, linear, feed-forward multicarrier power amplifier system that operates in the 60 MHz frequency band from 1930 MHz to 1990 MHz with an instantaneous bandwidth of 25 MHz. It consists of: • One outdoor enclosure assembly. • Up to six model G3S-1900-125 amplifiers (two per sector, each mounted in an MCR21929-1-2 two-way subrack). • Six Duplexer Low Noise Amplifier modules • Four 930-00018-005, 148-amp rectifiers. • One Low Voltage Disconnect system. • Four 12 Vdc 105 AH Batteries . • System Interface Module Designed for outdoor use, the IP54 rated enclosure is a sturdy aluminum cabinet with front and rear locking ventilating doors. Access to the RF, and alarm cabling is located at the lower sides and rear of the enclosure. Access to the AC power cabling is located at the left side AC panel of the enclosure The enclosure protects the Powerwave equipment from the outdoor elements as well as housing the System Interface Module (SIM) and the electrical interface for the 148-amp rectifiers and G3S-1900-125 MCPAs (Multicarrier Power Amplifiers). The all solid-state G3S-1900-125 plug-in amplifier module MCPAs, , are designed to produce high-peak power output. The modular construction and unique and highly effective Light Emitting Diode (LED)-based operation and fault indicators always display the current operating status of the amplifiers. The turn-on and turn-off sequence of voltages are fully automatic, as is overload protection and recycling. A nominal 52-Amps of current is required for the G3S-1900-125 amplifier at rated output power. Each of the three MCR21929-1-2 subracks, contain up to two MCPAs. The MCPA outputs are combined to provide one composite output per subrack. Each subrack is equipped with an Automatic Power Control (APC) circuit and an RF GAIN ADJUST potentiometer. The APC indicator and GAIN ADJUST potentiometer are located on the upper-right front of the subrack. Each subrack provides two RS-485 alarm interface ports, a preamp alarm interface port, a Form-C alarm interface port and an RS-232 maintenance port, as well as, RF IN, RF OUT and a –50dB RF sample port. The 148-amp rectifiers and associated subracks require primary input power between 176 to 264 Vac. The rectifier converts the AC input power to the +27 VDC for use by the system. The system design provides 12 minutes of battery backup time with P/N 920-00337-003 batteries under a full operational load (3 hrs 30 mins. under a light load). A Low Voltage Disconnect (LVD) monitors the output voltage of the battery system and disconnects the batteries from the circuit
044-05156 Rev C 7 when the battery voltage drops below 21 VDC. The LVD also provides the trickle charge path for the batteries during recovery and normal operation. The System Interface Module (SIM) monitors the performance and alarm state of the rectifiers, amplifier subracks, and Duplexer Low Noise Amplifier (DLNA) modules.

The transmit signals are combined (in the 16x16 configuration), amplified, then duplexed with the receive signals. The duplexed signals are presented to a bulkhead connector for interface with the antenna port. The duplexer provides coupled samples of the forward and reflected signals for BTS diagnostics. Received signals from the duplexed antenna are separated from the transmit signals in the DLNA. The receive signals are amplified by 45 dB through a low noise amplifier. The output signal is split into two paths, to allow for future system expansion. Each sector has two DLNAs, one for the primary receive path and one for the diversity receive path. The diversity DLNA only has transmit signals when the sector is expanded beyond eight carriers. The SIM assembly monitors the MCPAs, LNAs, LVD, and rectifiers, and reports alarms via the I2C and DALI interface.

The maximum input power for all carrier frequencies should not exceed the limits idicated in the system specification. The input VSWR should be 2:1 maximum (or better). 4.4 RF Output Load The load impedance should be as good as possible (1.5:1 or better) in the working band for good power transfer to the load. The amplifier is operated into a duplexer and will maintain its distortion characteristics outside the signal band even if the VSWR is infinite, provided the reflected power does not exceed one watt. A parasitic signal of less than one-watt incident on the output will not cause distortion at a higher level than the normal forward distortion (i.e. -63 dBc).
044-05156 Rev C 20 4.5 G3S-1900-125 Amplifier Module 4.5.1 Overview The G3S-1900-125 amplifier is a linear, feed-forward power amplifier that operates in the 60 MHz frequency band from 1930 MHz to 1990 MHz. It is designed to operate in two continuous frequency blocks in the PCS band or an instantaneous bandwidth of 20 MHz. A typical one-sector system is illustrated above. Each amplifier is a self-contained plug-in module and is functionally independent of the other amplifier module. The amplifier modules are designed for parallel operation to achieve high peak power output, and for redundancy in unmanned remote locations. Each amplifier in the system can simultaneously transmit multiple carrier frequencies at 85 watts per sector, for a combined output power of 170 watts. Each amplifier output is an amplified composite signal of approximately 125 watts before losses. All phase and gain corrections are performed on the signal(s) in the individual amplifier modules. Each amplifier module has alarm and display LEDs that display the amplifier performance. If a failure or fault occurs in an amplifier module, it is displayed on the individual amplifier front panel. The amplifier typically draws 52 amps of current at rated output power, and approximately 25 amps with no RF signals applied. Be sure to turn the amplifier off before removing it from the subrack to avoid damaging the equipment or causing personal injury. 4.5.1.1 Controls, Indicators, & Interfaces Primary +27 Vdc power is applied to the amplifier via a 100-amp circuit breaker (ON-OFF) located on the left side of the amplifier front panel. The plug-in amplifier module RF control and indicators, located in the center of the amplifier front panel between the cooling fans, are shown below. The status and RF control functions are described in detail in the Amplifier Module DC Indicators RF Switch Definition table. The alarms are described in detail in the Amplifier Module RF Control and Indicators Definition table. G3S-1900-125 Amplifier Module RF Control and Indicators

When lit, indicates that the -5 Vdc supply is greater than -7 Vdc and less than -2 Vdc. If the -5 Vdc indicator goes out, the DC Fail indicator will illuminate. This indicates that the -5 Vdc voltage dropped below -7 Vdc or increased above -2 Vdc. RF ON Switch Three position switch: Off (down position) - Turns off amplifier module. On (center position) - Normal amplifier on position. Reset (up position) - When toggled to reset position, all the red LED indicators will turn on one at a time in sequence followed by all the green indicators one at a time in sequence; this will also reset the fault latches. If the switch is held in the reset position, a microcontroller reset will occur. This will be verified by the LEDs toggling state again. The switch is spring loaded to return to the normal ON position when released. If a fault occurs and the MCPA is disabled, the alarms can be cleared and the MCPA enabled by this reset position. The functions of the switch are disabled for five seconds after a power-up condition.

Note 2: The Appropriate Status lamp will turn off, indicating which voltage is out of its range. (10% range for +15V, +5V, and -5V). The amplifier module has an average output of 125 watts power (1250 watts peak power) with intermodulation products suppressed to better than -63 dBc below carrier levels. The amplifier provides an amplified output signal with constant gain and phase by adding approximately 25 dB of distortion cancellation on the output signal. Constant gain and phase is maintained by continuously comparing active paths with passive references, and correcting for small variations through the RF feedback controls. All gain and phase variations, for example those due to temperature, are reduced to the passive reference variations. The amplifier module is comprised of: Preamplifiers Two feed-forward loops with phase-shift and gain controls Main amplifier DC/DC power regulator Error amplifier Alarm monitoring, control, and display panel
044-05156 Rev C 23 4.5.1.2 Main Amplifier The main amplifier employs class AB amplification for maximum efficiency. The error amplifier and feed forward loops are employed to correct signal nonlinearities introduced by the class AB main amplifier. The error amplifier operates in class AB mode. The RF input signals are amplified by a preamp and coupled to an attenuator and phase shifter in the first feed-forward loop. The main signal is phase shifted by 180 degrees and amplified in the premain amplifier. The output from the premain amplifier is fed to the class AB main amplifier. The output from the main amplifier is typically 180 watts. The signal is output to several couplers and a delay line. The signal output from the main amplifier is sampled using a coupler, and the sample signal is combined with the main input signal and input to the second feed-forward loop. The error signal is attenuated, phase shifted 180 degrees, then fed to the error amplifier where it is amplified to a level identical to the sampled output from the main amplifier. The output from the error amplifier is then coupled back and added to the output from the main amplifier. The control loops continuously make adjustments to cancel out any distortion in the final output signals.

There it is amplified to the same power level as the input sample and coupled on to the main output signal. The final output is monitored by the 2nd loop and adjusted to ensure that the signal distortion and IMD on the final output is canceled out. The input and output of the amplifier employ two-stage, class AB amplifiers, which provide approximately 25 dB of gain in the 60 MHz frequency band from 1930 to 1990 MHz. The amplifier operates on +27 Vdc, and is mounted directly on a heat sink, which is temperature monitored by a thermal sensor. If the heat sink temperature exceeds 85°C, a high temperature fault occurs. The alarm logic controls the transistor bias voltage, which shuts down the amplifier. 4.5.1.3 Error Amplifier The main function of the error amplifier is to sample and amplify the signal distortion level generated by the main amplifier, to a level that cancels out the distortion and IMD when the error signal is coupled onto the main signal at the amplifier output. The error amplifier is a balanced multistage, class AB amplifier, has 75 dB of gain, and produces over 100-watts peak output. The amplifier operates on +27 Vdc and is mounted directly on a heat sink. 4.5.1.4 Amplifier Monitoring In the main and error amplifier modules, all normal variations are automatically compensated for by the feedforward loop control. However, when large variations occur beyond the adjustment range of the loop control, a loop fault will occur. The alarms are displayed on the front panel indicators and output via a 21-pin connector on the rear of the module to the subrack summary board for subsequent remote monitoring via the ALARMS connector. 4.5.2 Amplifier Module Cooling
044-05156 Rev C 24 Although each amplifier module contains its own heat sink, it is cooled with forced air. Four fans are used for forced air cooling and redundancy. The fans, located on the front and rear of the amplifier module, draw air in through the front of the amplifier and exhaust hot air out the back of the module. The fans are field replaceable. 4.5.3 Intermodulation The G3S-1900-125 amplifier is designed to deliver a 125-watt composite average power, multicarrier signal, occupying a bandwidth less than or equal to 20 MHz, in the bandwidth from 1930 to 1990 MHz. The maximum average power for linear operation, and thus the amplifier efficiency, will depend on the type of signal amplified. 4.5.3.1 Two Tone Intermodulation When measured with two equal CW tones spaced anywhere from 30 kHz to 20 MHz apart, and at any power level up to the average power, the third order intermodulation products will be below -63 dBc 4.5.3.2 Multitone Intermodulation Adding more tones to the signal will lower individual intermodulation products. If the frequencies are not equally spaced, the level of intermodulation products gets very low. When the frequencies are equally spaced, those products fall on top of each other on the same frequency grid. The average power of all intermodulation beats falling on the same frequency is called the composite intermodulation; it is -63 dBc or better. 4.5.4 Amplifier Monitoring The amplifier has a separate remote alarm and control connector, which may be used by the host system to monitor and control the individual amplifier modules. The status, alarm, control, and power connections on the amplifier connector are made through a 21-pin male D-Sub combo connector and are listed and described in the Amplifier Module DC and Logic Connector Definition table.

Pilot tone frequency selection is based on the intended operational band of the amplifiers per the following table. Pilot Frequency Setting Based on PCS Frequency Block of Operation Transmit Frequency Band (MHz) Block Designator Base Station Bandwidth Pilot (MHz) A 1930-1945 15 1945.5 (A) D 1945-1950 5 1950.5 (D) B 1950-1965 15 1965.5 (B) E 1965-1970 5 1964.5 (E) 5 1965-1970 5 1970.5 (5) F 1970-1975 5 1969.5 (F) C 1975-1990 15 1974.5 (C) Block Pairs A-D 1930-1950 20 1950.5 (D) D-B 1945-1965 20 1965.5 (B) B-E 1950-1970 20 1970.5 (5) E-F 1965-1975 10 1964.5 (E) F-C 1970-1990 20 1969.5 (F) E-C Excluding F 1965-1990 Excluding: 1970-1975 25 1974.5 (C) Notes: 1. If the Block Designator has not been previously selected through serial communication on connector J10M, pilot defaults to 1960.5 MHz on the G3S-1900-80 amplifier; 1964.5 on the G3S-1900-125 amplifier 2. If the Block Designator is selected through serial interface on connector J10M, pilot frequency is moved to the appropriate spot and is stored permanently into the microprocessor until another band is changed. If the pilot tone is not moved and signals are transmitted in B-band, some traffic channels may transmit directly on the pilot tone. The pilot tone requires a guard band of 60 KHz for TDMA, 270 KHz for CDMA (IS-95), and 400 KHz for GSM. Transmitting on the pilot tone will cause the amplifier to go into Loop Fail. This will not damage the MCPA. However, CDMA customers will experience a Loop Fail in every sector where the amplifiers are installed. TDMA and GSM customers will experience intermittent Loop Fails in the sectors that use these frequencies. On the other hand, if the pilot tone is not moved and signals are transmitted in A-band (1930-1945) or C-band (1975-1990), the instantaneous bandwidth of the amplifier will be exceeded. This will cause equipment operated in the outer bands of the PCS band to experience higher intermodulation distortion, which may in turn cause them to exceed FCC emission limits. The lower end of the PCS band presents the farthest frequency span from the pilot tone, which begins at 1930 MHz; 30.5 MHz away from the pilot tone of the G3S-1900-80 amplifier; 34.5 MHz away from the pilot tone of the G3S-1900-125 amplifier. Setting the pilot tone frequency of the amplifiers requires a laptop interface program. The laptop can be connected to the multi-amplifier subrack’s RS-232 port. The multi-amplifier subrack provides the interface to the amplifiers to set their pilot frequency and stores this setting in memory. If an amplifier fails, the multi-amplifier subrack programs the pilot frequency of the replacement amplifier to that of the other installed amplifiers. Refer to the Site Preparation and Installation Manual or Field Replaceable Units manual for the pilot tone configuration procedure. Contact Powerwave to obtain a copy of the program and related instructions.
044-05156 Rev C 26 4.6 MCR21929-1-2 Amplifier Subrack 4.6.1 Overview The MCPA system is a linear, feed-forward power amplifier system that operates in the 60 MHz frequency band from 1930 to 1990 MHz with an instantaneous bandwidth of 20 MHz. It consists of an amplifier subrack with up to two 125-watt G3S-1900-125 plug-in amplifiers. The MCR21929-1-2 houses an RF power splitter/combiner and a control module that monitors the functional status of all plug-in amplifiers. Additionally, the subrack is equipped with an Automatic Power Control (APC) circuit and an RF GAIN ADJUST potentiometer. The APC indicator and GAIN ADJUST potentiometer are located on the upper front of the subrack as shown below. Each subrack provides two RS-485 alarm interface ports, a preamp alarm interface port, a Form-C alarm interface port and an RS-232 maintenance port, as well as, RF IN, RF OUT and a –50dB RF sample port. Only the two RS-485 alarm interface ports are used to report alarm status to the SIM. Subrack alarms are daisy chained together and address switches on the front panel are set to identify the appropriate sector. When two of the same model amplifiers are used, the system offers up to 218 watts of output power (after combiner insertion losses) using the 125-watt amplifier. MCR21929-1-2 (Reach-through (Pseudo) Front Access) - This 19-inch flush mount subrack has front “reach through” access to its interconnect panel located at the rear of the subrack. 4.6.1.1 Controls, Indicators, & Interfaces The location and function of the amplifier subrack controls and indicators is depicted below and described in the paragraphs that follow. MCR21929-1-2 Controls and Indicators 4.6.1.1.1 AO A3 (Address) Switch This four-position DIP switch is used for setting the external RS-485 alarm bus address. MCR21929-1-2 Address Switches 4.6.1.1.2 Config Switch This four-position DIP switch is used for selecting software features in the amplifier subrack. Refer to Gain Modes later in this section for a description. Preamplifiers are not used in this system, so the second dip switch is set to Off, as indicated below in the left two diagrams.
044-05156 Rev C 27 MCR21919-1-2 Configuration Switch 4.6.1.1.3 APC LED The LED indicator located on the top right-hand corner of the subrack serves several functions. Under normal conditions, the indicator is off. Anytime the APC function is engaged, either from an overdrive or voltage derating situation, the indicator blinks. When the overdrive or voltage derating condition is removed and all the gain is recovered, the indicator ceases to blink and remains off. During maintenance functions such as downloading firmware and detector calibration, the indicator blinks to signify the beginning and end of those functions. APC LED Sequence and Blink Rate Operation Sequence Blink Rate APC due to an overdrive On/Off 1 Hz APC due to an over voltage On/Off/Off/On 1 Hz APC due to an under voltage On/Off/Off/On 1 Hz System firmware upgrade On/Off 0.1 Hz Detector calibration On/Off 1 Hz 4.6.1.1.4 Gain Adjust This potentiometer allows the subrack gain to be attenuated 0 to 10 dB in Normal operating mode, or 0 to 3 dB in Constant Gain operation mode. Refer to Gain Modes later in this section.

If the output power of the subrack exceeds an “engage” threshold (see below) the gain is reduced. The LED indicator located on the top front-right of the subrack blinks when the APC is engaged. The gain is reduced until the output power complies with the “settle” range threshold. As the input drive reduces, the gain recovers by the amount needed to approach the nominal output power, until the original gain is achieved. Any power level in between the nominal and the engage threshold does not warrant a gain change. APC Limit Thresholds (Watts)(G3S-1900-125) MCPAs Nominal Engage Settle 1 109 122 112 2 218 244 222 4.6.3 Gain Modes The subrack can be operated in either standard gain or constant gain mode. The choice of two gain modes provides system design flexibility. Standard gain is the mode most often selected by system designers and is the factory default setting of the subrack. Standard gain mode changes the gain of a subrack based on the number of installed functional modules, while constant gain restricts the gain of the subrack to that of about one module, regardless of the number of modules installed. When a given sector is operated at full available power to maximize call capacity or when more system gain is needed, standard gain mode is best. At lower power level requirements or when a specific system gain value must be maintained, the system designer may elect to use constant gain mode instead. Constant gain mode maintains a consistent cell site coverage footprint while allowing N+1 redundancy and increased system reliability. By installing one more amplifier than the RF power plan requires, Constant gain mode allows for a back-up amplifier, should one of the cell site’s amplifiers become inoperable. Standard gain or constant gain is independently selectable on a sector-by-sector basis. Subrack Gain Active Gain Mode MCPAs Standard Constant 2 51.5 48 1 48.5 48
044-05156 Rev C 29 4.6.3.1 Standard Gain Overview and Application (Default Configuration) In the standard gain mode, the gain of the system is dependent on the number of amplifiers operating at a given time and the power from the amplifiers is used at or near their maximum limits. When the design of the cell site requires full power from the amplifiers installed in the subrack in order to achieve maximum call capacity, the standard gain mode should be used. For example, if the sector design calls for 150 watts (measured at the directional coupler output; assuming 1.5 dB of loss from the subrack to the directional coupler), the sector should be configured with two 125 watt amplifiers (154 watts at directional coupler; 51.5 dB subrack system gain) to take full advantage of the available power. The trade-off here, is that if an amplifier fails, the available power drops back to 77 watts, the overall gain drops by 3.0 dB, and all the transmit channel powers drop by 3.0 dB as well (i.e. 7.5 watts to 3.75 watts per channel). Gain adjustment via the front panel potentiometer is available. 4.6.3.2 Constant Gain Overview and Application In constant gain mode, the gain of the subrack remains the same, regardless of the number of amplifiers installed. Good engineering practice requires careful planning when using constant gain mode. When the design of the cell site requires much less than maximum power, but must maintain a specific radius of coverage, constant gain mode is ideal. For example, if the sector design calls for 75 watts output power at the directional coupler, the sector must be configured with two 125 watt amplifiers (87 watts; 48 dB gain) when constant gain is enabled to allow for amplifier failure. If an amplifier fails, the available power drops back to 43 watts, the subrack gain adjusts to remain 48 dB (77 watts), and all the transmit channel powers remain at the set power (i.e. 7.5 watts per channel). However, while in constant gain mode, if the sector power is set to maximum (i.e. 100 watts with two amplifiers installed), and an amplifier fails, the remaining amplifier will be over-driven and likely to go into an over power condition. Should this occur, the sector would go into APC control, the input power is attenuated (see paragraph 4-5), the sector’s footprint shrinks and an alarm is sent to the switch. Gain adjustment via the front panel potentiometer is available. 4.6.3.3 Gain Mode Control and Theory The MCR21929-1-2 subrack adds 3 dB of attenuation when constant gain mode is initially activated, reducing the system gain of the MCR21929-1-2 from a nominal of 51.5 dB to 48.5 dB. Therefore, whenever the gain mode is changed from standard gain to constant gain or visa-versa, the cell technician must reset the overall system gain or individual channel power. In constant gain mode, the gain of each carrier (or the system) must remain constant to avoid reducing the cell radius. When the subrack detects an amplifier failure, the amplifier subrack reduces input attenuation through the Voltage Variable Attenuator (VVA) by the amount of gain lost while the amplifier is removed from the circuit. This allows the system gain to remain constant, and allows the cell site to maintain a consistent footprint. When the replaced MCPA is enabled, attenuation is again added to the input port of the subrack by the amount of gain introduced by the replacement MCPA to maintain an overall subrack constant gain. As MCPAs are disabled and enabled, system gain is recovered within a 1-second time frame. The subrack is shipped from the factory with the configuration switch set for Standard Gain mode active. 4.6.4 Performance Derating With Lower Supply Voltage The MCPA system will operate at full power, while meeting all spectrum requirements, over a supply voltage range of 26 to 28 VDC. The MCPA System will meet derated spectrum requirements at derated output power levels over a supply voltage range of 21 to 30 VDC. MCPA System power derating levels are outlined in below. The LED indicator located on the top front right of the subrack blinks when the output power is derated. Power Derating Versus Voltage Profile Supply Voltage[VDC] Output Power Derating 28V ≤ V < 30V 0.5dB 26V ≤ V < 28V 0dB 24V ≤ V < 26V 0.5dB 22V ≤ V < 24V 1.0dB 21V ≤ V < 22V 1.5dB
044-05156 Rev C 30 As the voltage returns to nominal levels, the output power will return accordingly. Sufficient hysteresis of at least 0.1 V is included to eliminate 'toggling' at crossover voltage levels. 4.6.5 Amplifier Monitoring The amplifier alarms are displayed on the front panel indicators and output via a 21-pin connector on the rear of the module to the subrack summary board for subsequent remote monitoring via the ALARMS connector. The subrack interprets the amplifier alarms, reacts accordingly, and provides alarm status to the base station through both the Form-C and RS-485 alarm bus. Amplifier alarms may be monitored through the dry contact ALARMS 15-pin female D-sub connector on the rear of the subrack.

044-05156 Rev C 33 operational band of the amplifiers and must be set during commissioning of the base station, and anytime the MCR21929-1-2 subrack is replaced. Setting the pilot tone frequency of the amplifiers requires a laptop interface program. The laptop can be connected to the MCR21929-1-2’s RS-232 port. The MCR21929-1-2 provides the interface to the amplifiers to set their pilot frequency and stores this setting in memory. If an amplifier fails, the MCR21929-1-2 programs the pilot frequency of the replacement amplifier to that of the other installed amplifiers. 4.7 DLNA 4.7.1 Duplexer Overview The Duplexer Low Noise Amplifier (DLNA) module provides Bandpass filtering for both the uplink (receive) and downlink (transmit) paths, as well as gain for the receive path and alarm monitoring for receive gain and VSWR. The DLNA presents excellent return loss on all ports with 18 dB or better.

The LNA gain is controlled from a front panel 10-turn potentiometer. The LNA is set to 45 db of gain from the factory. The output of the LNA is further split into two paths, reducing the receive gain by approximately 3.3 dB, for input to the base station. The noise figure of the DLNA is typically better than 2 dB at room temperature including all DLNA components. The main receive path is used for the 8x8 configuration. The diversity receive path is used for the 16x16 configuration. A microprocessor in the DLNA monitors the current draw of the LNA. If the LNA current draw drops below a predetermined threshold, an LNA alarm is generated back to the SIM. In addition, a front panel LED is illuminated when the LNA fails.
044-05156 Rev C 34 DLNA Front Panel 4.7.3 Transmit Path Overview The transmit path receives amplified RF signals from the MCR21929-1-2 amplifier subrack. The amplified signals are filtered and duplexed with the receive signals and presented to the antenna port. The transmit filter provides 105 dB of isolation in the receive band between the transmit and antenna ports. 4.7.4 DLNA Alarms VSWR and LNA alarms for the DLNA are given on the front panel and sent via an alarm bus to the SIM. Close-up View of DLNA Front Panel Alarm indications for the DLNA are as follows: VSWR LED Green (ON) Normal Red (ON) Alarm State 1 Yellow (ON) Alarm State 2 Green/Red (OFF) Alarm State 3 Fast Flash Test Mode LNA LED Green (ON) Normal Green (OFF) Loss of Supply voltage
044-05156 Rev C 35 A front panel four-position rotary switch is provided to set the VSWR alarm threshold based on the length of cable from DLNA output (typically FSJ4 or LDF4) to the antenna foam jumper (typically 1 5/8 Heliax).

The rectifiers source 592 amps of combined output DC power at +27 VDC under normal operating conditions. The rectifiers are designed to operate on 180 to 264 VAC, single phase power, 47 to 63 Hz, and operate at 89% efficiency. They do not require any minimum load to operate. The rectifier system is modular in design. N+1 redundancy is built into the system, so a failure in one rectifier does not affect the performance of the base station. Each rectifier provides performance data and alarms to the LVD controller and the SIM. In addition to the 30 amp circuit breaker installed in the AC panel, each rectifier is protected by an internal 30 amp 3AG fuse. The rectifier front panel provides 3 LEDs for quick fault determination Rectifier LED Definitions LED Indication AC Good Green = OK Temperature OK Green = OK DC Good Yellow = OK

The LVD controller will accommodate other battery ratings, however, it is factory set for this battery. The batteries provide a minimum of 12 minutes battery backup time at 25 deg C when presented with the full cabinet load. The batteries have a wide operating temperature range of –40 to +60 deg. C.

They have also been tested in accordance with BS6290 Part 4. Two 600A fuses (Bussmann PN: TPL-CZ), located in the LVD, protect the batteries. 4.8.2.1 Battery Heater The battery heater is a thin, sheet-like element located between metal panels directly beneath the batteries. The battery heater receives 240 volts AC (400 W) directly from the AC panel circuit breaker through a temperature sensitive relay. The AC contacts of the relay close when the ambient temperature in the battery compartment drops below 0 °C (32 °F) allowing the heater to warm the compartment. The heating pad is turned off when the thermostat reaches 10 °C (50 °F). A separate temperature probe is placed in the battery compartment that is used by the LVD to adjust the charge voltage, and is independent of the battery heater. The battery heater generates 400 watts (1367 BTUs) of heat and has a maximum surface temperature of 200 ºC or 392 ºF. 4.8.3 Power Plant Monitoring A controller card in the LVD monitors the performance of the rectifiers. When each rectifier’s sense line is connected to the LVD, the rectifier is slaved to the control card for the final output voltage. Therefore, both the sense line and +27 Vdc bus between the LVD and the rectifier must be connected for the rectifier to supply the correct voltage to the system. The LVD control module may control up to 6 rectifier modules and adjusts rectifier output to the recommended battery float voltage for a given temperature. The LVD controller ensures that the rectifier outputs are balanced and monitors the rectifiers for failures. A potentiometer located on the front plate of the controller sets the float voltage at 25°C (77°F). The factory preset is 27.6 Vdc. Failures are reported to the SIM.
044-05156 Rev C 39 The controller also monitors the battery compartment temperature. The output bus voltage is adapted with consideration to the temperature changes of the batteries. The compensation slope is user selectable as one of three values: -36mV/°C (-20mV/°F), –60mV/°C (-33.3mV/°F), and between -10°C (14°F) and 60°C (140°F). The factory setting is –36mV (-3mV/°C/cell). If the probe is not connected or fails to open, the output voltage falls back to factory preset and an alarm is generated. The LVD controller card switch settings are given in the table below.

044-05156 Rev C 41 4.8.4 Low Voltage Disconnect (LVD) Low Voltage Disconnect Module The purpose of the LVD is to monitor the DC bus to regulate the rectifier(s) output voltage with regard to the needed operating voltage to the system, and the appropriate charge voltage for the batteries. Should AC power fail, back-up batteries are installed in the system to provide a relatively short operational period, based on the amplifier load at the time of failure. When the battery performance declines to a predefined limit (21 Vdc in this system), the LVD controller disconnects the batteries from the load through a 600 amp transfer switch. Disconnecting the batteries at this threshold prevents permanent damage to the batteries, thereby extending the battery life. Low voltage alarms sent to the base station provide sufficient time to do initiate an orderly shutdown of the base station before power is lost. LVD Rear Panel Connections

The SIM communicates with each amplifier subrack in the cabinet via the host RS-485 interface on the MCPA subrack. RS-485 signals are daisy chained from the first subrack to the next, and so on, until the buss is terminated. The SIM is internally terminated, as are each of the amplifier subracks, to prevent loading down the RS-485 buss. TBD alternate configuration: The MCPA Serial Interface is accomplished via six identical DB9 Female connectors.

TX refers to data in to the SIM. RX refers to data out from the SIM. Amplifier alarms are reported to the SIM via the amplifier subrack RS-485 bus. The amplifier subracks are daisy-chained on the RS-485 bus, and the alarm bus is cabled from the subrack rear panel to the front panel subrack interface panel. Each subrack has a unique address. The subrack address is set via front panel dip switches. Refer to Amplifier Monitoring in the MCR21929-1-2 Amplifier Subrack section of this manual for available alarms. 4.9.2 DLNA Alarms - DLNA Interfaces (J7 – J12) The DLNA interface is accomplished with six DB15 Female connectors. Each connection is unique and requires coordination with the DLNAs within the cabinet. Each connector provides DC power to the DLNA, differential I2C BTS pass-through, and analog temperature signals. DC power provides the DLNA with +27±1.0 Vdc via a 5A maximum circuit breaker on four contacts (2-source, 2-return). The circuit breaker also functions as the power switch to the DLNA. The differential I2C interface utilizes 6 contacts. These signals are passed-through the SIM to the BTS interface. A module detect signal is also passed through. No processing is provided or required. A single analog voltage signal (pin 10) represents the temperature of the DLNA module. The voltage potential is with respect to the DC return. The temperature conversion factor is: 0°C = 500mV +10mV/°C.

This interface includes up to six individual rectifier faults. The faults signals are open collector. The signal impedances are defined as: Low impedance signifies normal operation High impedance signifies a fault
044-05156 Rev C 46 The open collector circuit has a 10mA limitation. The interface also includes two auxiliary TTL signals. One is an input and the other an output. The auxiliary output signal is a 74HC14 inverter output. The auxiliary signals have no function at this time. RECT6 signal represents the alarm status of the LVD controller.

The intrusion inputs are contact closures from all of cabinet doors: front, rear, battery, and AC service. All Common contacts are tied to the system ground. The Normally Closed contacts are pulled-up and passed to the micro-controller. A logic high signal signifies an intrusion via an open door. The AC power fault passes through to the DALI interface Common contact with reference to the BTS COMMON1. An open contact signifies an AC fault. The AC fault signal is not processed.

The frequency of the square wave signal is directly proportionate to the RPM of the fan. The speed of the fan is dependant on the applied control voltage. The rotational speed of the fan is dependent on the applied DC voltage to the control input of the fan. The control function is supported by a micro-controller. The fan control ports will be forced to 0% PWM if the front door is sensed open. The fan status will latch to the current state and all fault times will be halted and saved. Upon the sensed door closure the fan sense routine will continue where it left off. The temperature information is derived from: o The DLNA temperature analog input. o The MCPA serial interface. o The SIM internal temperature analog input. The highest temperature measurement among these devices determines the fan setting. All four-fan control ports function identically with each other. The PWM outputs do not increment or decrement > 1 step per minute. If the +27V input is < 24V, the temperature thresholds increase by +10°C. If the voltage is less than 24V the battery back-up system is assumed the primary DC source and the system will operate at an accelerated temperature to reduce the current draw of the cabinet fans in an attempt to extend battery life.

Fan Fault Thresholds PWM (%) Fan Fault Threshold 100 - 50 40Hz 49 - 20 15Hz < 20 10Hz Each fan sense input is measured. If the fan frequency(s) is below the threshold (for the operating mode) for a continuous period of 1-minute a fan fault is reported to the DALI interface. Any change in fan status is reported to the BTS in real-time via the I2C interface. The fan fault on the DALI is cleared when all of the fan frequencies maintain above threshold performance for a period of 30 seconds. Alarm monitoring will halt if the fan control is 0%PWM. When this occurs, the current alarm status latches. The cabinet fan interface is a DB15 Female connector. The interface provides fan monitor inputs, and fan control / status outputs. The fan control circuitry provides a 0 to 10Vdc signal to adjust the fan speed.
