Changes or modifications not expressly approved by Kaval Telecom Inc. could void the users authority to operate the equipment. DCM000000018 Kaval Telecom Inc. v BDA1300 Equipment Manual 2 INTRODUCTION TO BDAs Bi-Directional Amplifiers (BDAs) are radio frequency amplifiers that amplify signals in two directions. There are two basic BDA Applications; Line Amplifiers and Off-the-Air... 2.1 BDA Line Amplifier System Application In-building RF distribution system usually takes on one of several forms including, but limited to, radiating cable, distributed tapped radiators, or high power repeater antennas. For in-building RF distribution system that requires some gain to compensate for the system loss, line amplifier is the best device for the job. Line Amplifiers provides amplifications of RF signals to recover signal loss contributed by radiating cable and other system components. Figure 1-1 shows an example of a subway tunnel RF distribution system using Line Amplifiers. The system consists of Line Amplifiers strategically inserted between radiating cables. As the RF signal travelling along the radiating cable, it loses strength because some of its energy is converted into heat. Line amplifiers recover the RF loss by amplifying the signal to the desired signal strength before sending it down the next section of radiating cables. Hence, the in-building RF seamless coverage can be maintained. 2.2 BDA Line Amplifier Diagram DCM000000018

'Kaval Telecom Inc. Page 2-4 of 51 BDA1300 Equipment Manual 2.3 BDA Off-the-Air Amplifier System Application The Bi-Directional Amplifier is intended to extend Cellular coverage into areas with coverage deficiency such as inside office buildings, shopping malls, hospitals etc. It is designed to be located independent of the donor site and must be equipped with its own antenna systems - one to communicate with the donor site and the other(s) to communicate with portables in the shadow zone. A typical in-building coverage extension system is shown in Figure 1-2. The head-end subsystem, namely Kaval bi-directional amplifier, is responsible for the amplification of both incoming off-the-air downlink signal and outgoing uplink signals. The in-building distribution antenna system comprises of Coaxial cable, Signal taps, splitters and antennas to extend coverage on every floor, basement and underground parking garage. 2.4 BDA Off-the-Air Drawing This distributed antenna system is based on Kavals patented Tapped Radiator RF signal distribution approach. The technology makes use of coaxial cable with Signal Taps strategically located and connected to Omni-directional ground plane antennas. This technology offers flexibility in system design, installation and optimization. Once the RF cable backbone has been installed, additional signal taps and antennas can quickly and easily be added to a live system, without the need to take the system out of service. Hence, new coverage areas can be added, or the system can easily be modified if the layout should change (e.g. modernization retrofits or process modifications). DCM000000018

'Kaval Telecom Inc Page 4-13 of 51 BDA1300 Equipment Manual 4.3 Power De-Rating Requirements BDAs will amplify all signals that fall within their Pass-Band range. The output power will be shared between all channels being amplified. Another multiple channel effect is Intermodulation signals produced from non-linear effects between the intended channel signals. These intermodulation may cause interference to receiving equipment. In order to minimize Intermodulation signals, Power de-rating must be applied. In the USA there are FCC Intermodulation Specifications published in the EIA Standard PN2009. The tables 2.2 shows the maximum per channel Output Levels allowed as a function of the number of channel. Note that depending on the actual amplifier input levels, the gain of the BDA may need to be reduced to comply with the above regulations. 4.4 Automatic Gain Control (AGC) Both Downlink and Uplink paths are equipped with AGC. The Amplifier based AGC has a dynamic attenuation range that ensures that a field set (adjustable) nominal composite output power is not exceeded. The AGC gain varies dynamically to maintain this composite power level by limiting strong signal levels which could cause excessive intermodulation. For example, if the AGC limit is set for +25 dBm and the gain of the unit is set for 40dB , then the AGC circuit will begin to attenuate composite incoming signals at +25dBm 40dBm = -15dB (composite power input). The AGC circuit will maintain this composite power limit even if the input signals increased. This composite level would be maintained by reducing the gain from 40 dB. For every 1dB increase in input signal there would be a 1dB decrease in the gain. The BDA Controller is used to set the AGC composite power threshold level. The AGC setting is a value ranging from 0 to 255. 4.5 AGC Threshold level Setting Composite Power Level Setting

The AGC Threshold level (in dBm) for the number of channels to be amplified is shown on the next page. This AGC threshold should be set to ensure intermodulation products do not exceed 13dBm. This table also shows the de-rated power per channel for the number of channels to be amplified. DCM000000018

As such the maximum EIRP will be at the first Tapped Antenna, which will be 12 dB below the maximum signal level of the BDA1300

+25 dBm, or 0.32 Watts EIRP. These Antennae are to be installed such that no person can touch the Antenna, or approach within 0.2 Meters. ANTENNA INSTALLATION WARNING ALL ANTENNA INSTALLATION IS TO BE PERFORMED BY QUALIFIED TECHNICAL PERSONNEL ONLY. ANTENNA INSTALLATION INSTRUCTIONS AND LOCATIONS ARE FOR THE PURPOSE OF SATISFYING FCC RF EXPOSURE COMPLIANCE REQUIREMENTS, AND ARE NOT OPTIONAL. ALL ROOF TOP ANTENNA INSTALLATION MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNA, OR APPROACH CLOSER THAN 10 METERS. ALL IN-BUILDING ANTENNAE INSTALLATIONS MUST BE SUCH THAT NO PERSON CAN TOUCH THE ANTENNAE, OR APPROACH CLOSER THAN 0.2 METERS. DCM000000018 Kaval Telecom Inc. Page 24 of 51 BDA1300 Equipment Manual 7 BDA Controller and Configuration Kavals BDAs can be configured very easily without the use of any tool via the BDA Controller. The BDA must be powered up before setting the BDA operating parameters. The operating parameters are set to specific defaults at the Kaval factory. All controller settings are recorded in the BDA Controller Settings As-built list. The customer may also reset these parameters to optimize BDA performance in the operating condition. 7.1 BDA1300 Controller Operation The BDA Controller is a microprocessor based part of a Kaval BDA that provides password protected, keypad entry of all system parameters including digital gain control, module fault monitoring, and battery backup control. It interfaces to the 28 VDC Power Supply, the optional 24 VDC Battery (both monitoring, transferring, and charging), control signals to the amplifiers, and provides monitored DC power for the amplifiers. The BDA Controller display is a 2 line by 20 character Vacuum Fluorescent (VFD) display. The connectors are all secure lock type and should only be plugged and unplugged with power off. 7.2 BDA Controller Drawing AGC UPLINK DOWNLINK PWR FAIL BATT BATT BOOST PA BOOST PA TEMP FAN SELECT BDA OK EXIT BDA CONTROLLER ON OFF ADJUST POW ER DCM000000018 Kaval Telecom Inc. Page 25 of 51 BDA1300 Equipment Manual 7.3 BDA Controller User Interface LED and Audible Indicators:

LED and audible indicators are used to enhance the user interface of the BDA. 10 LEDs and buzzer are described below:

PWR FAIL BATT Lights if primary power fails, and the system is on Battery Backup. UPLINK BOOST UPLINK PA DNLINK BOOST DNLINK PA UPLINK AGC DNLINK AGC TEMP FAN BUZZER Lights when the battery (if installed) voltage drops below 24 VDC which roughly indicates 50% of backup capacity remaining. This may occur as a result of normal discharge in a backup situation, battery exceeding its useful life, or a battery failure such as water loss or shorted cell. In addition, while running on battery backup, if the battery drops below 22 VDC, the LED will begin to blink indicating that self-shutdown is imminent. If the battery drops below 21 VDC the BDA will shut down completely to protect the Battery from damaging deep discharge. Lights if the Uplink Amplifier is enabled and has an overcurrent, undercurrent, or internal fault. Lights if the Uplink PA (Power Amplifier) is enabled and has an overcurrent, undercurrent, or internal fault. Lights if the Downlink Amplifier is enabled and has an overcurrent, undercurrent, or internal fault. Lights if the Downlink PA is enabled and has an overcurrent, undercurrent, or internal fault . Lights to indicate that an Input Signal of sufficient strength is present to cause the AGC circuit (if enabled) to act to reduce gain. The level at which AGC action occurs is not a fixed signal level. It depends upon the user setting for output level target. When lower targets are set, the AGC will begin to act at lower input levels. When AGC is disabled, the LED does nothing. If the Input Signal exceeds the AGC ability to reduce gain, an overload condition exists, and the AGC LED blinks rapidly. Operates the same as the Uplink AGC LED, but for the Downlink. Lights when the BDA system temperature, as detected by a digital sensor in the controller, exceeds the user programmed high temperature threshold. Lights when the Cooling Fan(s) (if enabled) have an overcurrent or undercurrent condition. The Buzzer sounds briefly during button presses for audible feedback. When a User Function requires a confirmation, a short beep is emitted. During a Fault Condition, a long periodic beep is sounded (this can be disabled). When the Battery is about to be depleted when on Battery Backup Power, the Buzzer will sound continuously. DCM000000018 Kaval Telecom Inc. Page 26 of 51 BDA1300 Equipment Manual SELECT EXIT ADJUST Functions:

BDA system parameters can be set using the four button BDA controller keypad. Description for the keypad buttons are listed below:

ON/OFF Power Switch for turning the BDA operation on and off. Note that this only controls the BDA Controller, Amplifiers, PAs, and Fans; the DC Power Supply is still operating where BDA controller is switched off. This Button is used to enter the Main Function Menu and Submenus, and where applicable to confirm a Function selection chosen with the Adjust Buttons. This Button is used to cancel any Function changes, reverting to previous settings. If a Fault has occurred and its Status is displayed, pressing the Exit Button clears the fault. These buttons Scroll up and down between Status, Function, and Menu display items. They also adjust programmable numeric values up and down. 7.4 Checking BDA Status Use ADJUST button to scroll through the Status menu such as Master status, current Monitor status and Thermal Monitor Status. The controller should display BDA OK otherwise it would display Fault! and the appropriate fault descriptions. 7.5 Setting BDA Operating Parameters Before allowing the operator to change operating parameters, at the Main Menu, the controller will ask the operator to enter a three-digit Password. The controller will skip the Password section if the field password is set to 0000 (disabled). To enter the password, the operator uses the ADJUST button to scroll up or down for the desired number, then depress the SELECT button to accept the number. The cursor will move to the next digit. For the password to be valid, all three digits password must be entered correctly, one at a time, starting from left to right. Note: Always write down the new password!

If BDA password is lost, the Network administrator must contact Kaval to clear the Password. BDA functions such as Gain, AGC, Battery, Temperature, Fans and Controller can be set through the Menu. However, only certain parameters should be modified in the field. All other parameters have been factory set based on the model configuration of the BDA and MUST NOT be modified. The chart below shows the BDA parameters which may require modification in the field (based on each specific BDA application). DCM000000018 Kaval Telecom Inc.

This has been achieved as follows :

!BDA Controller provides fault monitoring and accurate status report through LED.

! The 28V DC Power-supply is over-rated for actual requirements.

! Boosters are monitored for both Over-current and Under-current (most failures are sensed this way).

!Cabinet temperature is monitored for excessive temperature.

!Components are easily removable via quick connect DC and RF connectors. 8.2 Maintenance Philosophy 8.3 Field maintenance should require a screwdriver, a multi-meter, spares of each of the active BDA component parts, and a Portable Radio to monitor off the air signals. There is no requirement to have any test equipment to accomplish most service repairs.

! All BDA component parts have been designed for reliable long life operation.

! The BDA Controller performs ongoing extensive built in diagnostics.

! Corrective action can often be taken without detailed technical knowledge or the need for any test equipment. Troubleshooting Procedure 1. 2. 3. 4.
