Management Information Base is a virtual database used for managing the objects (parameters) in a communications network. Most often associated with the Simple Network Management Protocol (SNMP). The MIB database is hierarchical (treestructured). The software that performs the navigation in the MIB database is a MIB browser. The MIB database is Jotron proprietary and contains descriptions and definitions for all parameters in the radio. The MIB database is updated each time a new radio parameter is added or changed.

SDR



Software-Defined Radio is a system where components that traditionally have been implemented in hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) now are implemented by means of software on an embedded computing devices, i.e. a Digital Signal Processor (DSP).



SIP



Session Initiation Protocol is an IETF-defined signalling protocol, widely used for controlling multimedia communication sessions such as voice and video calls over the Internet Protocol (IP). The protocol can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) communication sessions consisting of one or several media streams.

SNMP



Simple Network Management Protocol is a UDP-based network protocol. It is used mostly in network management systems to monitor and control network connected devices like the Jotron radios. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects. SNMP exposes management data in the form of variables on the managed systems, which describe the system configuration. These variables can then be queried (and sometimes set) by managing applications like a MIB browser or a remote control unit.

VOGAD



Voice Operated Gain-Adjusting Device, is a type of automatic gain control for microphone/TX line amplification. It is used in radio transmitters to ensure correct modulation and to prevent clipping caused by overmodulation.



VoIP



Voice over IP (VoIP) is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the intranet/Internet or other packet-switched networks.



VDL mode 2



VHF Data Link Mode 2 is the datalink method defined by ICAO for Controller Pilot Data Link Communication (CPDLC). Physically the VDL mode 2 datalink uses D8PSK with a bit rate of 31500 bits/s on the physical (RF) interface.

1 Introduction 1.1 Design The Jotron Receiver and Transmitter are “State of the art” fully solid state design based on a Software-Defined Radio (SDR) concept with a Digital Signal Processor (DSP) as the core element. The DSP provide all signal handling between the IF signal format and the analogue audio signals and vice versa. This includes filtering, de-modulation, modulation signal levelling and more. The DSPs also handles all the control signalling within the RA and TA units, as well as external to the units. The units are software defined and are easily upgradable with new features or functionality if required. The units can be controlled either locally or remotely using several communication protocols including RS232, RS485 and various protocols over an Ethernet (LAN) connection. The RF frequencies are controlled by synthesisers within the equipment and the units are tuneable within its full frequency operating range.

Note. Unless otherwise noted, the lowest assignable frequency for each of the radios is 118.000, the highest assignable 25 kHz channel is 136.975, and the highest assignable 8.33 kHz channel is 136.990, corresponding to the frequency 136.99167 MHz. Optionally, the frequency range can be expanded to 144.000 MHz or 156.000 MHz. Throughout this manual, the term transmitter, TA, TR, TR-7750 or TR77xx refers to any variant of the transceiver unless specifically noted in the text, and the term receiver, RA, RX or RA-7203 may be used for the receiver unit (RA-7203).The operating procedures for the different RX/TX models are equal. 1.3



Power supply models



Model PSU-7006 (Standard) PSU-7007 (Option)



P/N X-87700



AC input 85 – 264V



DC input 19.0 - 31.2 V



X-89000



85 – 264V



19.0 - 31.2 V



DC Output DC 28.0V when AC is present DC input when AC is absent DC 28.0V when AC is present DC 28.0V when AC is absent (internal DC/DC converter)



The DC output is the voltage fed to the transmitter module. The transmitter module is able to provide full 50W output power when the DC is above 26.0 VDC, it will therefore give the full power output when using the standard power supply, PSU-7006, as long as the input voltage is kept above 26VDC, below 26VDC the output power will be gracefully reduced to maintain a perfect modulation spectre. When using the optional power supply, PSU-7007, the full (50W) output power is achieved down to a DC input voltage of 19.0VDC. This is possible since the PSU-7007 includes a DC/DC converter that will maintain a normal output voltage to the transmitter unit.

1.5 Layout of the transceiver The receiver unit, RA-7203 operates as an independent receiver. The transmitter unit TA-7650 operates as an independent transmitter, but requires a power supply unit; PSU-7006 or PSU-7007 for operation using AC power. The receiver and transmitter units may be placed in entirely different geographical locations or together in a single enclosure, it may also be configured as a transceiver with local operation from the front panel.

1.6 Applications The transmitter TA-7650 and the receiver RA-7203 can be used either as a standalone transmitter / receiver for ground to air voice or data communication, or combined as a transceiver with RX muting and common audio control via the interface of the Transmitter unit. The following operating scenarios are available: • • • • • •



•



Locally as a Transceiver, with microphone and headphone connected directly to the front panel connector. As a Transceiver, connected to a VCS (Voice Control System) using 600-ohm analogue lines for audio, together with keying in form of in-band tones, external voltages, ground or phantom keying (E&M signalling). As a Transceiver, connected to a VCS (Voice Control System) using Ethernet (LAN/WAN) for VoIP audio, keying and signalling. Connected to a VME (VHF ground station) system as a data modem, using TCP commands to control the radio as a physical VDL mode 2 transceiver. Connected to a VDL (VHF ground station) system using 600-ohm analogue lines for audio that contains the AM-MSK data from an external ACARS modem. In a combined system where the radio is connected to an IP based VCS, an analogue based VCS and a local system using microphone/headset. The radio can be set up to automatically select the audio from either of the systems based on the keying source. This flexibility makes the radio ideal to use in a transition phase between an analogue and an IP based VCS system. In addition the transmitter/receiver has a large range of options for remote control using Ethernet, serial lines or front panel controls.
