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.

Note LED indications described here (see ) apply only during diagnostics mode (i.e., not during normal operation).
2) Rx LED -when illuminated, indicates receive activity. Only applicable during RX Tests. 3) Tx LED -when illuminated, indicates the transmitter is in a keyed state. 4) Software Operational LED -when illuminated, indicates the software is operating properly. 5) Unassigned LED -This LED does not have a functional indication. 6) Fault LED -when illuminated, a fault has been detected. See Monitors/Faults. EIC Controls and Indicators: Diagnostic Mode Indications
.0.1 Monitors/Faults A monitor is a comparison of a sensor measurement to a predetermined limit or range. Monitoring of sensors is an ongoing process while running the diagnostics application. When a sensor measurement is out of range, a fault is generated. Detected faults result in the illumination of the red LED, and a corresponding message, which is viewable under the Faults menu. Monitor tests are selectable via the menu items TX Monitors, RX Monitors, or PSMonitors. When selected, a measured value used by the sensor comparison, and a Pass (“P”) or Fail (“F”) indication will be displayed. The P/F indicates the results of the comparison to the valid range limits. If a monitor is not enabled, an “NA” will be displayed. Monitors are enabled automatically according to the state of the transceiver. (i.e. some TX Monitors are enabled only when the transmitter is in the keyed state.) Even though monitors are always active when enabled, only one can be displayed at a time. Before starting the display of a monitor, a previously displayed monitor must first be stopped by selecting it a second time. The Fault LED is cleared on reboot.
