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

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.

EIC Controls and Indicators: Diagnostic Mode Indications
![](/img.php?id=1249760&img=bg1a.png)
.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.
