DMR_Manager Operating Manual 2011/07/04 Version 1v2 INTRODUCTION This document illustrates the applications and how to use the Radio Activity DMR base stations management software. Radio Activity DMR base stations can support a lot of applications and the management software is designed with forms for reading the parameters that can change depending on the particular application. For that reason the forms shown in this document may be different from the ones in use or they could not appear in your application if the specific functionality is not enabled. Some forms may be incomplete because it is a work in progress, please notify us errors or inconsistencies. Reserved Document – Don’t forward without authorization Page 4 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 CONCEPTS OVERVIEW The Radio Activity DMR Base Station can include several TRX (master and slaves), where TRX refers to a transmitter, one or many receivers, DSP, IO board and a power supply. Radio Activity DMR Base Stations allow many different applications: they can work like a single repeater or in a radio network made of different repeaters linked together in different way such as Ethernet link, RF link. 2.1 TRX ARCHITECTURE The core of “physical layer” of the system is a unit which via software performs every function of signal processing into radio station. So, it is not necessary to add boards (like synchronizers, phase and amplitude equalizers, signal decoders, modem, etc.) because the functions can be implemented by routines which can be freely matched, downloaded and with superior performance. Communication and control functions of module are entrusted to a microprocessor which manages communications with external world and with other equipment modules. The microprocessor is based on LINUX operative system; it can manage a LAN ethernet 10/100 interface both for copper line and for optical fiber links, it is equipped with 4 serial ports to manage radio modules, GPS, auxiliary devices, external hosts; it is equipped with a Real Time Clock with tampon battery; it controls an embedded PLL to synchronize the entire station upon an internal (VCTCXO 0.5 ppm) or external temporal reference. DSP module is equipped with a synchronous serial port according RS485 standard levels, which can be programmed up to 16Mbit/s and can be used to interconnect together more transceiver or additional equipments. Main performed functions are the following: ∞ Frequency self-tuning device ∞ Deviation self-calibration device ∞ Analogical and digital demodulation ∞ RF circuits testing ∞ Phase modulator calibration ∞ RF output power control ∞ Low frequency lines management ∞ DMR protocols management ∞ Digital signals processing ∞ Management, conditioning and routing of traffic and remote control signals from and towards external world Receiver can be supplied as single or double for space diversity reception. Main and diversity channels are completely independent and coherent (sharing the same local oscillators) and they are designed according to an heterodyne structure, with vectorial conversion to base-band. Channel standard bandwidth is 12.5 KHz, but the receiver is prepared to accept also a settable channel bandwidth of 25 KHz, 20 KHz, 10 KHz (with double funnel option) for special applications. Receiver module is managed by a microcontroller unit whose program is hosted inside internal e2prom flash memory to lower parasitic emissions. This FW can be loaded through serial connection. The microcontroller, in addition to managing internal function of the unit, transfers measured parameters to the control unit through 115.2 Kb/s serial line. Reserved Document – Don’t forward without authorization Page 5 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 The board is realized with surface mounting components (SMD) to maximally reduce dimensions. On the frontal panel 2 LEDs are placed for monitoring internal PLLs lock status. Transmitter module is realized with surface mounting components (SMD) and it is housed in a shielded, 8TE box for 220mm Eurocards, with an heatsink mounted on side, with a thermal resistance of about 1.2°K/W. The unit can be extracted from the front side of the rack. On the frontal panel two LEDs are placed to monitor the transmitter status. Base-band functions, equalizing, limiting, low-pass filtering end eventual emphasis functions are performed by the DSP unit, which provides also for nominal and maximum deviation calibration by looping modulator with receiver. Modulator is digital vector, then the synthesized signal by local oscillator implements the frequency shifting of the signal which has been directly modulated in base-band by DSP unit and transferred to transmitter through its I and Q components. The amplifier is realized by three cascaded stages and RF output power regulation (between 1 and 25W) is implemented by controlling the stages. Power amplifier works in C class and ensures a very high efficiency, lowering the needed power from supply system and lowering the thermal dissipation inside the cabinet. Direct and reflected output power are measured by a directional coupler. Power control circuit acts in a closed loop and keeps constant the total power at MOSFET drain. Inside the module a thermal sensor is hosted and it is directly connected to the internal microcontroller which enables the command for air forced cooling fan of the cabinet if the temperature rises over 85°C. Anyway, if reflected power or mosfet temperature exceeds protection threshold, regulation circuit will lower output power up to safe levels for transmitter. The current flowing into final amplifier transistor is continuously monitored by microcontroller to verify the correct functioning and to reveal any efficiency degradation. The module is equipped with an harmonic filter to lower spurious emissions under required levels by existing regulations. 2.2 RADIO ACTIVITY DMR REPEATER AND UPGRADEABILITY TO SIMULCAST NETWORK Radio Activity DMR repeater is designed to be modular from both HW and SW point of view, to maximize its flexibility and minimize costs, physical dimensions, consumptions. Basic model already has all the characteristics to work as a double standard repeater with all the features of analogical and digital service. It can be equipped with double receiver to counteract fading effects through diversity space reception. It is set to host communication and synchronization embedded devices to make the network expandable to a multi-frequency or single-frequency multi-site system, with different types of links, operating with different transportation system topology, like microwave, UHF, optical fibers, IP connections. Privileged communication interface is Ethernet standard type, compatible with more diffused technology. This interface supports not only voice and data digital traffic, but also remote control management, which for Radio Activity equipment is very powerful: it is possible to have a complete monitor system of equipment status, it is possible to modify each parameter, to down-load each SW and configuration, launch self-test and calibration functions, to perform specific tests through internal embedded function generators and software analyzers of the station. For analogical voice traffic instead, a 2/4 wire and criteria line interface is available. Reserved Document – Don’t forward without authorization Page 6 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 Remote control service can be performed through an Ethernet connection pre-existing in the site, or through GPRS modem which can be integrated into the station, or through the radio channel and another Radio Activity station. Fully modular structure allows to best configure the radio equipment, by adding and/or changing the required HW and SW functional blocks, to work as simple repeater, multi-frequency multi-site repeater, singlefrequency multi-site repeater. 2.3 NETWORK It is possible to configure the network in many different ways, with different kinds of links (Ethernet, RF, Optical fibers) 2.3.1 MASTER BASE STATION IN “RF LINKED” NETWORKS The master base station is equipped with a “voting system”, which select the “best” signal among all the signals received by the Satellites and the local receiver(s). Besides this the master sends the digital synchronization towards the satellites and, in the case of Base Stations “RF linked” equalizes the absolute and group delay due to the RF channel. 2.3.2 SATELLITE BASE STATION IN “RF LINKED” NETWORKS The duty of the Satellite is: ∞ receiving the signals from the terminals and sending them to the Master through the RF link, ∞ transmitting to the terminals the signals received by the Master (voted) through the RF link. The satellite performs also the group delay and absolute delay equalization on broadcasting transceivers both down link and up link. 2.4 SIMULCAST NETWORKS Simulcast type networks operate on the same radio channel on the whole coverage area. Communications can be both open and selective channel, semiduplex mode between mobile terminals or duplex mode between Central and terminals. The network will make the automatic selection of accessing terminals and will broadcast the signal on the same frequency throughout the coverage area. The terminals are served regardless of their position as if they were covered by a single repeater. fc fc fc All transmitters send the same information signals on the same carrier frequency Reserved Document – Don’t forward without authorization Page 7 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 2.4.1 SYNCHRONIZATION, VOTING AND EQUALIZATION Simulcast radio network are able to realize the maximum radio coverage of the territory with minimum use of radio frequency. In a simulcast network, unlike a cellular system in which each cell is characterized by a particular frequency, all the terminals operate at the same frequency, like a big cell. Therefore it is necessary that the carriers of all transmitters are frequency locked and phase coherent with the master one. Frequency synchronism of the Radio Activity station can be extracted from multiple sources, depending on network needs and the references availability, and transmitted to all the base stations from the master one. This signal is received from all the satellites that reset their clock on it. In this way all satellites are zeroed in frequency compared to master and then zeroed between them. If there is not a good frequency synchronization the quality of communication considerably decreases in the equal fields strenght areas. Another essential function of Radio Activity simulcast networks is the voting, which is the method by which the best signal received from the network is continuously selected. The signal voted is sent to the satellite and then diffused in the whole coverage area. Simulcast networks require also particular attention in the choice of media linking the various stations. The characteristics of these media must be such as to make as much as possible identical signs of low frequency (audio) that each station must retransmit. For that reason simulcast networks made by Radio Activity employ equalization devices based on Digital Signal Processing, which are able to automatically minimize the differences between the media paths This feature allows to use a large family of communication media, including time-varying lines as pupinized copper, presenting considerable variations in temperature, or as non-dedicated telephone lines and therefore subjected to variations of delay and BF response.

This means that through the same radio channel broadcast by radio network, two digital communications can be established, and the radio channel capacity is doubled. The use of two timeslots allows also to exchange control signalling while radio communication is in progress, in order to manage, for example, the communication priority or to remote control the terminals functionality . 12.5KHz 30ms CH1 CH4 CH2 7.5KHz C C C C C C C C H H H H H H H H 1 2 1 2 1 2 1 2 Time Group 1 CH3 7.5KHz Frequency Two contemporary and indipendent communications on the same frequency carrier Group 2 A physical radio channel is identified by a couple of frequencies (Duplex and Semiduplex). Digital modulation requested by DMR standard (4FSK) allows an increased data transmission capacity compared with analogical traditional systems. In fact the system supports data transmission speed up to 9.6 Kb/s over the 12.5 KHz wide radio channel. It is possible then to implement data services with added value between terminals and the operative central, like for example radio traffic management and messages, localization through GPS (Global Positioning System) management, telemetry, with performances greatly better then what analogical systems can offer Reserved Document – Don’t forward without authorization Page 9 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 2.5.1 ALARM MESSAGES This feature of Radio Activity DMR Base Stations allows the user to bind some events with the sending of short text messages: when a certain event occurs, the user will receive the text message on the designed mobile terminal and a warning message when the problem is resolved (see Alarm Events Setup).

The connection mode and the connection parameters are normally stored on the PC under the item Profile , which you can modify according to your needs. Selecting the item Default it is possible to set the profile that will be used when the program start up (if the loaded profile already is the defined profile, the Default button will not be active). You can now modify an existent profile, or create a new one clicking on New profile . In both cases you must choose the connection mode (IP LAN or COM1-COM9 serial connection) A serial connection requires the setting of the following parameters: Reserved Document – Don’t forward without authorization Page 13 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 ∞ port speed (600 bps – 115,2 Kbps); ∞ bit per character (7 – 8); ∞ parity (nothing, even, odd); ∞ stop bit (1 – 2) ∞ possibility of activating the HW control flow (RTS/CTS) ∞ possibility of activating a connection through a modem rather than a direct connection (if this is the case you must specify the phone number and the Modem Reset button will be activated). The requested parameters for a LAN connection are only the IP address and the TCP port (normally port 4000) necessary for the remote control: You can also specify the remote control address of the device (if you do not select the item Define Address (hex) the broadcast address will be used) Note: Normally you need not to specify the remote control address. You must specify it if you want to connect to the remote device through the RF channel of the local one (future feature), or if you have a Base Station configured as 1+1 and you want to connect to a TRX even if it isn’t the active one. If you have made a simple change of the parameters of an existing profile, the program automatically require saving the modified parameters: You can save the parameters in the case of permanent change, but it is also possible to continue with the modified parameters not saved: in this case a subsequent restart of the program will present the original parameters on the profile you worked with.

Reserved Document – Don’t forward without authorization Page 34 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 DMR users are interested only in using the section Line 1 . It is possible to set nominal levels for input and output lines, high and low pass filters and delays. The input signal in fact, after the analog to digital conversion, is regulated in amplitude according to the user’s settings. The echo canceller is a filter that sums the output signal, after an appropriate phase correction, with the input signal, in order to minimize signal reflection effects. This function is selectable by checking Echo canceller There are also band pass and notch filters to remove PTT and sync tones. The filters are automatically inserted if you select a tone in the setup line section. You can define the level and the frequency of the used tones and the filters are automatically aligned with the desired frequency. The extracted signals are sent to the decoding tones block. The Line delay block allows to delay the input signal up to 127 ms using a 2 us step. The processing chain towards the balanced output is the reversal of the processing chain for an input signal. The In Line and Out Line sections allow to specify the PTT, squelch, synchronism criterions setting the level and the frequency of the signal. To activate these functions click on Imposta Linea . TELEPHONE INTERFACE SETTINGS (FOR ANALOG USE ONLY) The telephone interface settings are usually set by the technical staff for the specific application. The section to set these features is the following. Reserved Document – Don’t forward without authorization Page 35 of 51 DMR_Manager Operating Manual You must check Line user 2011/07/04 if there is a user side telephone interface, or Version 1v2 Line PSTN if there is a subscriber side telephone interface (BCA-C). The Busy Tone Decoder function activates the engaged line recognition algorithm (used in the automatic radio-telephone interface). The Freq Ring Gen box allows to set the frequency of the telephone call signal (usually 25Hz), which is active only in user side interfaces (bca-u). The box Num Ring C.ta allows to set the number of rings after that the telephone interface automatically engages the line. It is active only for subscriber side telephone interfaces (bca-c). 6.2.2.7 MULTICHANNEL All DSP modules have a connection bus “MTCH” that allows different radio systems to synchronously exchange data in particular network configuration. This feature allows to realize many different solutions. The MTCH bus can hold both anlog audio signals in 16 bit digital format and synchronism/signalling/control parameters. It is possible to connect up to 12 transceivers directly ,to perform a digital audio matrix in case of complex base station solutions. Reserved Document – Don’t forward without authorization Page 36 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 The MTCH protocol is configured on 28 timeslots, selectable to transmit or receive.

The timing of the Base Station can be extracted from different sources: Reserved Document – Don’t forward without authorization Page 38 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 Menu item Description Synchronism source Allows to choose the synchronism source No sync No Synchronism source selected Digital Synchronism based on a proprietary pattern sent at the beginning of the transmission and then on superaudio tones. Internal The synchronism source is a crystal oscillator placed inside the DSP module, which has a stability better than 0.5 ppm in the thermal range of functioning. On demand, higher stability oscillators can be used. The frequency tuning is digitally controlled and the setting can be stored. An internal self calibration function allows to correct the natural aging of the oscillator, by simply connecting the receiver to a calibrated external source. From multichannel The synchronism is obtained from Audio LAN connection clock (patch cord on the rear of the rack). This synchronism can be required for systems with more digitally linked together radio stations. Equipment synchronization time <2 s Long period relative stability 0 ppm Short period relative stability <0,001 ppm From PPS GPS The GPS receiver (inside the station) provides a pulse every second, which is used by the DSP to clear its frequency and time reference. The time reference allows automatic equalization of absolute delays of the links (useful in networks with IP links or MUX SDH links with automatic reconfiguration of routes in case of backbone failure). In the case of GPS failure the synchronism is automatically switched to super-audio tone received from the master station (see following method). Equipment synchronization time <120 s Long period relative stability 0 ppm Short period relative stability <0,01 ppm From superaudio A super-audio tone, superimposed to the analog signal, is the reference for the DSP to lock its internal clock. That tone, whose frequency can be freely set between 3100 and 3400 Hz (typ = 3400Hz), is sent 10dB lower than the nominal audio level. Equipment synchronization time <60 ms Long period relative stability 0 ppm Short period relative stability <0,01 ppm From 4 FSK timeslot Synchronism based on the 4FSK timeslot To enable these functions click on Set ; All the parameters will assume their original values if you restart the device, unless you perform a Save in eep operation (see the DMR LAYER CONFIGURATION paragraph). 6.2.2.9 SUBTONE / SUPERTONE Clicking on RA-DMR RadioConfiguration Subaudio/superaudio the subaudio/superaudio form will appear: Reserved Document – Don’t forward without authorization Page 39 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 This form allows the user to control and modify the subaudio and superaudio parameters.

You can set these parameters specifying the numbers in the section on the right: Initial setting time [ms] is the searching time for the best signal initially, Hold time [ms] is the time the voted source is maintained. Switch time [ms] is the time step after which a different input can be voted as the “best”, Hysteresys [dB] is a threshold: if another signal is Hysteresys [dB] better than the currently voted one, that signal become the new voted one. To enable these functions click on Set ; All the parameters will assume their original values if you restart the device, unless you perform a Save in eep operation (see the DMR LAYER CONFIGURATION paragraph). 6.2.2.11 DMR LAYER CONFIGURATION Displays the colour codes set in the channels table These parameters are set by the technical staff according to the network configuration It indicates activity on the radio channels Displays the quality of the signal received on the timeslots Reserved Document – Don’t forward without authorization Page 41 of 51 DMR_Manager Operating Manual 2011/07/04 Version 1v2 The Parameters section allows to enable different features: ∞ 4FSK modem: enables the 4FSK modem performed by the DSP, ∞ Receiving as terminal: if checked, the Base Station receives as it were a terminal, without the repeater features, ∞ Transmission as Base Station: if not checked, the Base Station transmits as it were a terminal, without the repeater features, ∞ Enabling DMR repeater: enables the repeater features. Hang time is the time that elapses after the killing of communication to the state of hibernation of the base station. During this time if the terminal accesses the network it does not need to perform the dehibernation procedure and acquisition of synchronization, but can simply access the network. After this time a terminal, to access the network, must “wake up” the base station by the hibernation state and acquire the synchronization. Hold time is the time the TX remains on air after the PTT release. The Signalling section displays radio activities on the two timeslots and also some measures about the quality of the radio channel. 6.2.2.12 DMR OPERATING MODES This form allows the user to enable the radio network in simulcast or multisite mode.
