Congratulations on your purchase of the LINKnet platform. Successful operation of the LINKnet in any installation depends upon sound system design. Service personnel should be aware that most problems experienced with LINKnet systems are due to failures or inadequacies in equipment outside the LINKnet platform. This manual pertains to the LINKnet Platform. It describes how the user should install, set-up and use the LINKnet Card-cage, Power Supply Module, and Plug in RF and Controller modules, for proper operation and safety. The scope of this manual is generally limited to the LINKnet circuitry itself; no attempt is made to thoroughly discuss all aspects of system or applications design. KAVAL TELECOM INC. would be pleased to discuss the engineering aspects of LINKnet installations and can undertake overall LINKnet system design and installation. The LINKnet encompasses the functionality of most of KAVAL TELECOM INC.s current electronic product line. All OFR and BDA products are harmonized into a single modular and adaptable system. The intention is to incorporate the functionality of most or all of KAVAL TELECOM INC.s product line into a single modular family. Newer technology allows implementation of additional features such as Digital Control, Self-alignment, and Extensive Diagnostics, which make the modules in this new generation of products more capable than their predecessors. The product is made up of at least one Card-cage, RF Modules, and a Power Supply. The Modules in the Card-cage interconnect via a back plane that supplies power and digital control signals. A single Card-cage can be mounted into a 6 unit standard EIA 19 inch rack, with multiple Card-cages interconnected using a Card-cage Interconnect Harness. An optional Control Module may be used to program and monitor the independent RF Modules. By daisy chaining Card-cages together, a single control module can be used to run up to 110 RF Modules in a single, integrated, system. Printed: 00.03.22,09:08 Revision Date:3/22/00 3 LINKnet !

One 24V Battery is required for each Card-cage (usually consisting of two 12V The battery must be a Sealed Lead Acid type (often called Gel Cell). Batteries must be installed in a ventilated area in accordance with the If a longer cable assembly is required, contact the KAVAL TELECOM INC. factory For battery capacity in Amp Hours (A-H) see section Battery Sizing below. For charging time for batteries, in hours, see chart below. If batteries are stored (not connected to the system) they should not be left in a low state (discharged) for more than a few days, or they will permanently lose capacity, and no longer be able to run the system. If it is desired to be able to recharge the batteries at a rate faster than is inherent by E-mail: info@kaval.com. in the power supplies internal system, then it is possible to use an external charger. Consult the KAVAL TELECOM INC. factory for details at E-mail:

info@kaval.com Battery Sizing The size or capacity of the external lead acid batteries is dependent on two variables: The number of modules installed in the Card-cage and the desired back up period in hours. The relationship is defined by the following equation:

iv LINKnet OFR400 RF MODULES ! USER MANUAL DCM000000019 1 . O F R 4 0 0 M O D U L E S Overview Theory Of Operation An OFR, or On Frequency Repeater, is a radio repeater that simultaneously receives and transmits a single narrow band radio channel on exactly the same frequency. The OFR accomplishes its repeater function without store and forward circuitry, or expensive conventional simulcasting techniques. The fact that the same frequency is retransmitted by an OFR means that additional frequency allocations are not required in situations where an existing radio coverage pattern needs to be extended. The most common OFR applications are the extension of above ground signals into buildings, tunnels, vehicles or the extension of radio coverage patterns into outdoor shaded areas such as deep valleys. From an applications standpoint, an OFR is very similar to a regular two-way radio repeater. On Frequency Radio Repeaters can be combined using regular two-way radio multicoupling or duplexing equipment and have input and output signal characteristics to those of regular transmitters and receivers. The one special consideration in OFR systems is that of input to output antenna isolation. This must be carefully engineered for each installation. Standard On Frequency Radio Repeaters are designed for indoor use only and are intended for mounting in a standard EIA 19 inch rack. Modular design of OFR circuitry allows for easy servicing, stocking of spares, adaptability and upgrade ability.

USER MANUAL DCM000000019 Power On Self Test (POST) Each system module automatically performs a self-diagnostics when inserted into the system Card-cage. These tests determine that the unit is a) correctly installed in the Card-cage and b) not damaged in transit. All six of the LEDs on the front panel will flash 3 times If the LEDs do NOT flash three times, then remove the module, check the power If the card is OK the LEDs will continue normally. (See Normal Operation) If there is a fault, then the Red Fault LED will remain on. If this occurs, contact your KAVAL TELECOM INC. Service Representative, (See Warranty / RMA Procedures). source, and re-insert the module, (See Installation Instructions). The Power On Self Test is Not an RF test, it only verifies that there is power to the unit and that the logical circuitry is functioning. Printed: 00.04.11,13:13 Revision Date:4/11/00 8 LINKnet OFR400 RF MODULES ! USER MANUAL DCM000000019 Normal Operation The OFR400 Module has six LEDs on the faceplate:

1. OPERATING - Under normal operating conditions, this LED will flash GREEN when RF Data is present. 2. STAND BY Under the control of the Controller Module, the OFR400 Module has the ability to act as a duplex transmitter, sitting perpetually in Stand by Mode waiting for the primary transmitter to fail. This LED should be constant Amber. If a Fault should occur with the primary module, the Stand by unit will immediately become the primary unit, at which time the Stand by LED will be turned off and the LEDs will show an operating Module. 3. Transmit This Green LED will be on when a signal is being transmitted 4. Receive This Green LED will be on when a signal is being received 5. Program This LED will be constant Amber when the unit is being re-

programmed by the Controller Module. This will signify that the unit is powered on but unavailable for use. 6. FAULT Red LED, If the internal diagnostics for the module detect a problem, then this LED will remain on Printed: 00.04.11,13:13 Revision Date:4/11/00 9 LINKnet OFR400 RF MODULES !

USER MANUAL DCM000000019 All Antenna Installation is to be performed by Qualified Technical Personnel only. Antenna Installation Instructions and locations below are for the purpose of satisfying FCC RF Exposure Compliance requirements. The Roof Top Antenna for linking to the Donor Site is a directional (high gain) Antenna fixed-mounted physically on the side or top of a building, or on a tower. The Antenna Gain must be no more than 10 dB. The Roof Top Antenna location should be such that only Qualified Technical Personnel can access it, and that under normal operating conditions no other person can touch the Antenna, or approach within 10 meters of the Antenna. The In-Building Antenna connection is via a coaxial cable distribution system with Signal Taps at various points connected to the fixed-mounted Indoor Antennae. This is shown in the figure in the Introduction. The Indoor Antennae are simple 1/4 Wavelength (0 dB Gain) types. They are used with KAVAL TELECOM INC. 12, 16, or 20 dB Cable Taps. As such the maximum EIRP will be at the first Tapped Antenna, which will be 12 dB below the maximum signal level of the LINKnet (+37 dBm); +28 dBm, or 0.63 Watts EIRP. These Antennae are to be installed such that no person can touch the Antenna, or approach within 0.2 Meters.
