ATH2422607700 MHz LAND MOBILE REPEATER

October 2009 3800 Digital Repeater Operating Manual 1 -1 Section 1 Section 13800 Information 1.1 General Description The EF Johnson Technologies 3800 Series Digital Repeaters are designed specifically for radio trunking operations. The 3800 integrates the functions of radio repeater and trunking channel controller into one unit. See Figure 1.1. Figure 1.1 3800 Series Digital Repeater 3800 Information 1 -2 3800 Digital Repeater Operating Manual October 2009 The radio component provides a transmitter and receiver with software programmable frequency and power selection. Transmitter and receiver signals are encoded and sampled by dual Digital Signal Processors DSP). Channel controllers in each repeater manage the control and traffic channels for frequency assignments and transmitter power level. The local site controller is integrated into one of the repeaters. The Trunked IP25 System supports the ability to have backup site controllers, but only one site controller is required per site. Multiple repeaters may be used per site to accommodate multiple frequencies, traffic level, and provide radio channel backup. One repeater is required for a control channel and one or more repeaters for traffic channels. A built-in ethernet interface lets the repeater communicate over the Trunked IP25 System IP network to other system components. 1.1.1 Models & Features The 3800 Series Repeater consists of various models and features. Please refer to the 3800 Digital Repeater Service Manual for descriptions of the different models, identification and part number information. 3800 Information October 2009 3800 Digital Repeater Operating Manual 1 -3 1.2 Functional Description The EF Johnson Technologies 3800 Series Digital Repeater is a trunked repeater with built-in trunking control. The Trunked IP25 System Channel Controller function is integrated into the repeater subsystem. The 3800 Repeater uses frequency synthesizer and Digital Signal Processor (DSP) technologies to provide digital control of the radio channels. Software defined configurations allow for quick updates and programmable operating frequency, output power, and other key functions. Multiple repeaters may be used per site to accommodate multiple frequency bands and provide radio backup. The 3800 is comprised of the following functional modules ( Figure 1.2): Figure 1.2 3800 Repeater Subsystem Functional Diagram Channel Controller All channels are managed by the integrated Channel Controller. The controller provides overall channel control for control and traffic channels in a repeater. It manages the radio transmitter and receiver frequency assignments and power levels. The Channel Controller checks channel status and reports any 3800 Information 1 -4 3800 Digital Repeater Operating Manual October 2009 channel failures or processing errors to the Site Controller. One Channel Controller is used for each radio repeater subsystem (in multiple repeater systems). TXDSP Module The TXDSP module manages the repeater radio transmitter interface. This module provides channel encoding with forward error detection and correction coding. It receives data packets from the channel controller and creates a signal for the transmitter. Radio Transmitter The Radio Transmitter is digital synthesizer based to ensure on-frequency and high stability operation. It converts the processed signal from the TXDSP module into a radio frequency (RF) signal for transmission. Radio Receiver The Radio Receiver is digital synthesizer based to ensure on-frequency and high stability operation. It receives and converts the radio frequency signals for processing by the RXDSP module. RXDSP Module The RXDSP module manages the repeater radio receiver interface. It processes the received signal samples from the radio receiver into data packets. The module then sends the data packets to the Channel Controller. Ethernet Interface The repeater communicates over its Ethernet interface with the Site Controller, Dispatch Console, and Network Management System (NMS). EIC Module The EIC module provides a user interface to the repeater including a 2-line display and push button rotary knob for menu navigation. 3800 Information October 2009 3800 Digital Repeater Operating Manual 1 -5 Power Supply The power supply accepts the AC line power input and converts it into the various DC power requirements of the repeater. 1.3 System Configuration The 3800 Repeater is typically used as the repeater component in an EF Johnson Technologies Trunked IP25 TM Configuration of 3800 repeaters is performed through the Network Management System (NMS). Refer to Section 3.3, “Trunked System Operation”in this manual for system operating information. System. This is an Internet Protocol (IP) Local Area Network (LAN) based radio system. Using a IP network configuration lets a system administrator manage the radios and system components exactly as if they were computers on a LAN. See Figure 1.3. 3800 Information 1 -6 3800 Digital Repeater Operating Manual October 2009 Figure 1.3 Trunked IP25 System 3800 Information October 2009 3800 Digital Repeater Operating Manual 1 -7 1.4 Safety Information This repeater emits radio frequency (RF) energy when transmitting. Make sure to observe all RF energy exposure standards when installing, testing, repairing, and operating this radio equipment. The FCC has adopted a safety standard for human exposure to RF energy. Proper operation of this repeater under normal conditions results in user exposure to RF energy below the Occupational Safety and Health Act and Federal Communication Commission limits. - Do not allow the antenna to touch or come in very close proximity with the eyes, face, or any exposed body parts while the repeater is transmitting. - To comply with FCC RF exposure limits, do not operate the transmitter of a stationary radio (base station or marine radio) when a person is within fourteen (14) feet [four (4) meters] of the antenna. - Do not operate the repeater in expl…
