TB7300 Installation and Operation Manual Description 9© Tait Limited December 20151 DescriptionThe Tait TB7300 base station is a robust state-of-the-art digital fixed station that combines Tait’s proven strengths in reliability and high performance with software-based configurability and operation, digital signal processing and voice-over-IP technology.The base station is designed for operation in a Digital Mobile Radio (DMR) Tier 2 conventional or Tier 3 trunked radio network. The ability of the base station to link stations using standard Internet Protocol communications, and to add features through software options ensures that DMR systems designed with the TB7300 are scalable in both size and functionality. The TB7300 can also operate as a simple, conventional analog repeater with CTCSS1 subaudible signaling2.The base station combines industry-leading digital voice quality with rugged design specifications and intuitive user interfaces. These products have been designed to meet the demanding needs of professional radio users.Its Ethernet interface provides built-in network connectivity. This network supports voice-over-IP in DMR networks, and remote management of all base stations via a web browser.1. Private Line (PL).2. Multi-site operation with voice-over-IP connection will be supported in a later release.

10 Description TB7300 Installation and Operation Manual© Tait Limited December 20151.1 FeaturesThe following are some of the features of the base station:■Fully compliant with the DMR Tier 2 and Tier 3 Standards. Can therefore interoperate with any similarly compliant radios.■Analog conventional repeater operation.■Can be completely managed remotely from a PC running a web browser: configuration, alarm monitoring, fault diagnosis, feature and firmware upgrades. Alarms can also be reported via SNMP traps, allowing integration with an SNMP-based network management system.■Rugged construction with generous heatsinks and fan-forced cooling for continuous operation from –22°F to +140°F (–30°C to +60°C).

TB7300 Installation and Operation Manual Description 11© Tait Limited December 20151.2 Frequency Bands and Sub-bandsMuch of the circuitry in the base station is common to all frequency bands, and is therefore covered by a single description in this manual. In some cases the descriptions refer to specific bands or sub-bands, and these are identified with the letters listed in the following table.Frequency Identification Frequency Band and Sub-band 50WB band B3 = 148MHz to 174MHz ✓

12 Description TB7300 Installation and Operation Manual© Tait Limited December 20151.3 ApplicationsThe TB7300 is designed for operation in a Tait TN9300 DMR Tier 2 conventional radio network, a Tait TN9300 DMR Tier 3 trunked radio network, or as an analog conventional repeater.In a DMR Tier 2 conventional network it can operate as a stand-alone repeater, or as a member of a multi-site system (under the supervision of a DMR conventional node). Since DMR provides two logical channels (timeslots) simultaneously for each radio frequency (physical channel), two users can alternately access the same frequency, one in each timeslot. Base stations on different sites can be linked together to form channel groups. A base station can support two channel groups, one in each timeslot.In a DMR Tier 3 trunked network it can operate as a traffic channel or a control channel. With two logical channels for each radio frequency, a single TB7300 base station can provide two traffic channels, two control channels, or both a traffic channel and a control channel.In analog operation it can operate as a conventional repeater with CTCSS1 subaudible signaling2.For more information, refer to the DMR System Manual.1. Private Line (PL).2. Multi-site operation with voice-over-IP connection will be supported in a later release.

TB7300 Installation and Operation Manual Description 13© Tait Limited December 20151.4 LicensesSome operational functions of the base station are controlled by licenses. These functions will not work unless you purchase the appropriate feature license and enable the feature set controlled by that license. The feature sets currently available are listed below.The base stations in a Tait DMR Tier 3 Network are controlled by a node (DMR trunking controller). The TB7300 is compatible with two types of Tait node: Express and Access. Each type of node has different capabilities. Refer to TN-2134 for more information.A base station operating as an analog conventional repeater needs the TBAS301 license.DMR Trunking Express(TBAS302)A base station with this license can accept connections from any Express node/standalone node or Access standalone node. In single-site trunking and fallback modes, this license entitles a standalone node to control a single site of up to 20 physical channels.DMR Trunking Access(TBAS303)A base station with this license can accept connections only from an Access standalone node. This license entitles a standalone node to control a single site of up to four physical channels.DMR Conventional(TBAS304)A base station with this license can operate in a Tait DMR Tier 2 conventional network. It can operate as a stand-alone repeater, or as a member of a multi-site system (under the supervision of a DMR conventional node).A base station with both a DMR Conventional license and a valid DMR trunking license (such as Express or Access) can be configured to operate in either mode. This enables a DMR Tier 2 base station to be reconfigured and re-used in a DMR Tier 3 trunked network.Analog Air Interface(TBAS301)A base station with this license can operate as an analog conventional repeater.

14 Description TB7300 Installation and Operation Manual© Tait Limited December 20151.5 Theory of OperationThe RF input is fed directly to the receiver board, while the RF output is via the exciter and PA boards. The control board also receives signals from, and sends signals to, the system interface, the Ethernet interface, and the front interface (see Figure 1.1).The Ethernet interface carries voice over IP and also allows maintainer access via a web browser. The control board carries out signal processing and has overall control of the base station. The control board converts information between analog and digital and controls the maintainer’s access via the Ethernet interface. It performs the air interface signal processing for digital DMR operation, gives the base station an identity as a network element, and provides the physical connections for the Ethernet and system interfaces.Figure 1.1 Base station high-level diagramRF InputRF OutputReceiverBoardPABoardSupplyInterfaceBoardExciterBoardFrontInterfaceControlBoardSystem Inputand OutputEthernet Interfaceto Network

TB7300 Installation and Operation Manual Description 15© Tait Limited December 20151.5.1 Signal PathsFigure 1.2 gives an overview of signal paths within the control board. Digital DMR signals from the receive RF interface pass through the digital receiver and DMR modem to the control software in the RISC processor. The control software passes the signal through the Ethernet interface to the node controller.Input to the Ethernet interface is from the node controller. This input is processed by the RISC and passed through the DMR modem to the transmitter.Analog FM signals from the receive RF interface pass through the digital receiver and are converted to G.711 before being modulated and retransmitted.1.5.2 Online and Offline ModesThe base station normally operates in Online mode, but you can put it into Offline mode via its web interface.Online Mode In Online mode, the base station performs its normal functions. Offline Mode Some procedures, such as activating firmware or running certain diagnostic tests, require the base station to be in Offline mode. This takes the base station out of service.

40 Working with Base Stations from Your PC TB7300 Installation and Operation Manual© Tait Limited December 20154.4.4 Working with Configuration FilesAt any time, you can save the current configuration settings as a file (Tools > Files > Configuration > Backup configuration). This is stored in the base station, but we recommend that you download it and store it on your computer as an off-site backup. The base station identity and network identity are not saved as part of the configuration file.You may want to develop a master configuration and upload it to all base stations in the network. The master configuration can contain all the different channel configurations and can be common to all base stations. The base station identity selects the default channel.Base stations are delivered with a default configuration which provides a safe set of values. We recommend that you download it and store it on your computer as a backup before changing and saving any configura-tion settings.You can also generate a report containing all the base station’s configuration settings (Tools > Files > Configuration > Configuration report), which can be saved as a text file. We recommend that you do this when the base station is commissioned. This report can be useful later if there is a problem with the base station. Comparing the original report with the later one may highlight changes in configuration that are causing a problem.4.4.5 Setting Up Custom AlarmsEach of the base station’s 12 digital inputs can be used to raise a custom alarm when the input goes high or low. The Custom Alarms form (Configure > Alarms > Custom Alarms) allows you to assign a name to each custom alarm, and to configure whether the alarm is triggered when the digital input goes high or low. Custom alarms are reported via the web interface and SNMP traps.Custom alarms are used to provide an alarm when an external event activates a digital input. You can rename any of the available alarms to provide a more meaningful name, such as “Door open”.Take care when setting the severity of alarms, including custom alarms (Configure > Alarms > Severity). Setting an alarm’s severity to Major will cause the node to take the base station out of service when the alarm is raised. Refer to the Help for more information.

TB7300 Installation and Operation Manual Working with Base Stations from Your PC 41© Tait Limited December 20154.4.6 Preparing to Download FirmwareNew versions of base station firmware are remotely downloaded to base stations from a package server (a web server application). You can set up a single computer to be the central package server for all the base stations on your network, using a web server of your choice. Tait also provides the Mongoose1 web server as part of the base station firmware package for use with a temporary package server, such as a laptop.The base station firmware package can be downloaded as a zip file from the Tait support website.This procedure describes using the Mongoose web server.Installing the Firmware PackageThe installation procedure copies files into a folder and adds items to the Windows Start menu (Start > Programs > Tait Applications > TB93002). From the Start menu you can then access the Help, licenses, manuals and release notes for each firmware package, and also start Mongoose.You do not have to install Mongoose to make it work, because it is a self-contained executable file. Once started, it will run in the back-ground until stopped, or the computer is shut down. Mongoose must also run from the same folder as the firmware files.1. Save the zip file to a suitable location on the hard drive of the pack-age server computer.2. Extract the zip file, then navigate to the root folder and double-click TB9300.msi to run the Windows installer.Notice Tait recommends that the maximum length of the path to the location of the extracted files is 100 characters. Using a longer path may cause the files to be extracted incorrectly.1. Mongoose runs on Windows only.2. The TB7300 is designed to use the same firmware and download system as the TB9300.

42 Working with Base Stations from Your PC TB7300 Installation and Operation Manual© Tait Limited December 2015Setting Up a Central Package ServerIt is beyond the scope of this manual to describe the exact procedure for setting up a central package server for any particular network. Tait expects that each customer will configure their own package server according to the requirements for their network.However, you do need to configure each base station with the IP address and port of the package server computer.1. Log in to the base station and select Configure > Base Station > Miscellaneous.2. Under Package server, enter the IP address and port number of the package server.3. Download the firmware as described in the Help.Notice The base station has enough space for two firmware pack-ages. If the base station already has two packages, delete the unwanted package before downloading another.Setting up a Temporary Package ServerIf you want to use a laptop as a temporary package server, you can temporarily override the package server IP address and port in each base station.1. Run Mongoose on the temporary package server (Start > Programs > Tait Applications > TB7300 > Mongoose).2. Windows Firewall may raise a Security Alert about allowing Mongoose to access your network or the internet. a. In Windows 7 allow access to private networks.b. In Windows XP click Unblock.3. Log in to the base station and select Tools > Firmware > Download.4. Under Package server, enter the IP address of the laptop. The default port number is 8080.5. Download the firmware as described in the Help.6. If you have trouble with any of the above procedures, please consider the following points:■The firmware download process uses the HTTP protocol. If you are using a laptop from outside the radio communications network, make sure that HTTP traffic can get through the firewall.■If Mongoose fails to start, it may already be running, or another application may be using port 8080. ■If the error message “Could not find index file” appears when listing packages, Windows security may be silently blocking access for Mongoose. Turn off the laptop’s WiFi and temporarily disable its firewall, then try again.

TB7300 Installation and Operation Manual Working with Base Stations from Your PC 43© Tait Limited December 2015■The base station has enough space for two firmware packages. If the base station already has two packages, delete the unwanted package before downloading another.4.4.7 Checking for Interference on a Receive ChannelYou can use the Signal Level page (Diagnose > RF Interface > Signal Level) to look for sources of interference across a range of receive frequencies.The chart on this page has two lines. One shows the current RSSI measurement for the selected frequency. The second shows a historical trace of peak RSSI readings on that frequency.

TB7300 Installation and Operation Manual Installation 45© Tait Limited December 20155InstallationThis chapter provides information on the site requirements for your TB7300 equipment and also describes how to install the base station in a standard 19 inch rack or cabinet.If this is your first time installing a TB7300 base station, we recommend that you read the entire chapter before beginning the actual installation.

TB7300 Installation and Operation Manual Installation 47© Tait Limited December 20155.1.3 Equipment VentilationAlways ensure there is adequate ventilation around the base station (refer to “Cabinet and Rack Ventilation” on page 48). Notice Do not operate it in a sealed cabinet. You must keep the ambient temperature within the specified range, and we strongly rec-ommended that you ensure that the cooling airflow is not restricted.Notice The cooling fans are mounted behind the front panel. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the fans disconnected (e.g. for servicing purposes).5.1.4 Ambient Temperature SensorThe ambient temperature reading for the base station is provided by the temperature sensor located inside the chassis.

48 Installation TB7300 Installation and Operation Manual© Tait Limited December 20155.1.5 Cabinet and Rack VentilationRefer to Figure 5.1 on page 49.Adequate cooling airflow is critical to the performance of the base station. The cooling airflow for the base station enters through the front panel and exits at the rear of the tray. For optimum thermal performance, the heated air that has passed through a base station must not be allowed to re-enter the air intakes on the front panel. Each base station requires an unobstructed airflow of 18m3/h (11cfm).To allow enough cooling airflow through a cabinet mounted base station we recommend the following:■A distance of 5cm minimum clearance to any obstruction to the front of the tray.■An open area of at least 50cm2 (8sq.in.) per tray of ventilation slots or louvres in front of the air intakes for the fans for each tray; for example ten 6×85mm (0.25×3.3in.) slots will allow the recommended airflow.■A distance of 10cm minimum clearance to any obstruction to the rear of the tray.■An open area of at least 50cm2 (8sq.in.) per tray of ventilation slots or louvres in the top of the cabinet, or to the rear of each tray.■A distance of 7.5cm minimum clearance to any obstruction to either side of the tray.■A 2U gap at the top of the cabinet.The ventilation opening must be unrestricted. If the slots or holes are covered with a filter, mesh or grille, the open area must be increased to allow the same airflow as an unrestricted opening.The maximum ambient temperature entering the cabinet must not exceed the maximum temperature specified for the base station.If the base station is installed in a rack or cabinet with other equipment with different ventilation requirements, we recommend that the base station be positioned below this equipment. Auxiliary Extractor FansIf multiple base stations are fitted in a cabinet, auxiliary extractor fans may be required to ensure adequate cooling. If fitted they should be capable of extracting 18m3/h (11cfm) per base station in the cabinet.If you have any other configuration, the performance of your system will depend on how closely you comply with the base station airflow requirements described above.

TB7300 Installation and Operation Manual Installation 53© Tait Limited December 20155.4.2 Customizing the ConfigurationThe following steps provide an overview of the process used to configure the base station with the settings it needs. Refer to the Help for detailed information.1. Log in to the base station (refer to “Connecting Your PC to the Base Station” on page 28 for more details).2. Select Configure. The base station has many different settings that can be configured before it is put into operation, such as:■channel configurations■alarm control and SNMP agent■network interfaces■quality of service■CWID■miscellaneous items such as NTP and package servers.3. Make the changes needed in each form and click Save.We recommend that you save the configuration to your PC or network. First make a backup copy of the configuration (which is stored in the base station as a file), then save this file to a folder on your PC or network. This provides a backup which can be restored to the base station if the configuration information becomes lost or corrupted.

54 Installation TB7300 Installation and Operation Manual© Tait Limited December 20155.4.3 Restricted Port NumbersCertain configuration settings in the base station’s web interface require you to enter a port number (for example, the trunking interface). Two ranges of port numbers are unavailable for use with the base station. The web interface will prevent you from entering a number from these ranges, as explained below.5.4.4 Changing the Root PasswordNotice The following procedure can be carried out only if secure shell access (SSH) is enabled. Secure shell access to the base station is disabled by default from version 1.35 onwards. To enable SSH, select Tools > Settings > Secure shell and click Start. The root password to the Linux operating system of the base station is a possible security risk. The equipment is delivered with a default password that is well known. Knowledge of the password could be used to render the equipment inoperable, for example by deleting files. If you are concerned about the security risk that this poses, change the password. If Tait provides support services, it may need to know the password.Notice If you change the password and then lose it, the equipment must be returned to Tait. Make sure that you store the password securely and do not lose it. To change the root password, follow these steps.1. Log in from your PC to the base station using SSH client software such as PuTTY. The username is “root” and the default password is “k1w1”. 2. At the # prompt, enter the command “passwd”.3. Follow the on-screen instructions.4. Record the password in a secure location. Restricted Port Numbers Details0 – 1023 The “well-known ports”, commonly used by other devices in a network. Using a port number in this range could cause compatibility problems with other devices.12000 – 14999 Reserved for internal use in the base station. Using a port number in this range could cause the base station to malfunction.

TB7300 Installation and Operation Manual Installation 55© Tait Limited December 20155.4.5 Tuning the ReceiverBefore the base station is installed on site, you may need to tune the receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 2MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency. The receiver in the B-band base station covers one of the following frequency bands, depending on the model:■B3 - 148 to 174MHzEach of these bands is split into 2 sub-bands:■B3 - 148 to 159MHz and 159 to 174MHzEach sub-band has its own helical filter (shown in Figure 5.2 below) which is electronically switched in or out of circuit depending on the frequency programmed into the base station. The bandwidth of these helical filters is approximately ±1.5MHz. To check the RSSI level and tune the receiver front end (if required), follow these steps.1. Place the base station on its side or upside down to allow access to the holes on the base to tune the helical filters.2. Log in to the TB7300 and select Monitor > Interfaces > RF Interface. For information on connecting directly to the base station, refer to “Connecting a Networked PC to a Base Station” on page 31.Figure 5.2 Identifying the B-band receiver front end helical filtersB3: 148 to 159MHzB3: 159 to 174MHz

56 Installation TB7300 Installation and Operation Manual© Tait Limited December 20153. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the RF input. Check that the RSSI reading on the RF Interface page is –80dBm ±1dB. Note this reading.4. Set the TB7300 to the new receive frequency.5. Change the RF input signal to the new receive frequency at –80dBm. Check that the RSSI reading is –80dBm ±1dB. If it is, the receiver front end does not require tuning. If it is not, go to the next step.6. Using the Johanson tuning tool1, adjust the correct helical filter for the new frequency (as shown in Figure 5.2) to obtain a peak RSSI reading. This reading should be within 1dB of the reading at the previous frequency. Adjust the center resonator of the filter first, followed by the two outer resonators (in any order). Each resonator should require approximately the same amount of adjustment when tuning.A change in frequency of 5MHz requires approximately one turn of the tuning slug. If tuning to a lower frequency, adjust the slug in (clock-wise); for a higher frequency, adjust the slug out (counterclockwise). 7. Change the RF input signal and the receive frequency to 0.5MHz above and below the required frequency and check that the RSSI reading does not drop by more than 0.5dB from the reading at the required frequency.8. Recalibrate the RSSI at the new frequency (Calibrate > Calibrate > RSSI). If you wish to confirm the accuracy of the tuning procedure, carry out a sensitivity measurement at the new frequency.1.

TB7300 Installation and Operation Manual Installation 57© Tait Limited December 20155.5 Installing the Base Station on Site5.5.1 Base Stations for Trunked SystemsWhen installing base stations that are part of a trunked system, it is very important to observe good site engineering rules. This is especially true when the channels are combined into a single antenna. If at all possible, the RF planner should avoid frequency plans in which the Rx to Tx spacing is an exact multiple of the trunked channel spacing, thus forcing Tx intermodulation products to fall outside the Rx channels. Cables and antennas should be of high quality construction. Solid shield heliax type cables are best, but if braided shield cables must be used for short distances, their braids must be silver-plated. Isolators should be used at all transmitter outputs. When the outputs of more than one transmitter are combined, their voltages add, and the resulting peak envelope power is not simply the sum of their powers, but is equal to the power of one of them multiplied by the square of the number of sources. Cables, components, and hardware must be rated to withstand the peak envelope power.During the commissioning process, all transmitters should be activated together using a diagnostic test tone, while the receiver RSSI is monitored. There should be no perceptible increase in RSSI while the transmitters are active.5.5.2 Equipment RequiredIt is beyond the scope of this manual to list every tool that an installation technician should carry. However, the following tools are specifically required for installing the base station:■Philips #2 tip screwdriver used to connect the DC power cables to the DC power terminals■Pozidriv PZ3 screwdriver for the M6 screws used to secure the tray to the cabinet in Tait factory-assembled systems■8mm spanner for the M5 nut on the ground connector.You can also obtain the TBA0ST2 tool kit from your regional Tait office. It contains the basic tools needed to install, tune, and service the base station.

$58 Installation TB7300 Installation and Operation Manual© Tait Limited December 20155.5.3 Mounting the Base Station1. Fit the base station into the cabinet or rack and secure it firmly with an M6 (or 0.25in if you are using imperial fittings) screw, flat and spring washer in each of the four main mounting holes b, as shown in Figure 5.3 on page 58.2. The base station can be wall-mounted by rotating the front mounting brackets and fitting the optional rear brackets (TBBA03-01). When the base station is wall-mounted ensure the airflow is from bottom to top (front panel mounted down) or side to side.3. For transport or in installations subject to vibration, the base station should be supported at the rear using a transit bracket (Tait recommends using the TBBA03-04 transit bracket).Cabling We recommend that you route all cables to and from the base station along the side of the cabinet so the cooling airflow is not restricted.Cables should be well supported so that the connectors or terminals on the base station and on the ends of the cables do not have to support the full weight of the cables.Cables must be routed so that they do not restrict the air outlets at the rear of the base station.
