1 Description The 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. Its Ethernet interface provides built-in network connectivity that allows the base station to join with other base stations to form a channel group.
1.1 Software Applications The TB7300 operates in both P25/AS-IP and DMR/MPT networks. Within these networks, the base station utilizes distinct P25/AS-IP and DMR/MPT software applications. 1.1.1 Base Station Features The following is a list of base station features for both P25/AS-IP and DMR/MPT software applications: P25/AS-IP DMR/MPT Non-Application Specific ■ Fully compliant with the P25 Common Air Interface. Can therefore interoperate with any similarly compliant radios.
1.2 Frequency Bands and Sub-bands Much 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.
1.3 Software Application Details 1.3.1 P25/AS-IP With the P25/AS-IP software application, the TB7300 is interoperable with TB9400 base stations, and therefore operates in P25 conventional networks and analog conventional networks. It operates as a stand-alone repeater/ base station, or as part of a channel group, providing receiver voting and simulcast transmission. All air interfaces and system types support simulcast operation.
1.3.2 DMR/MPT The TB7300 is designed for operation in a Tait TN9300 DMR Tier 2 conventional radio network, a Tait TN9300 DMR Tier 3 trunked radio network, an MPT-IP network, or as an analog conventional repeater. In a DMR Tier 2 conventional network, the TB7300 can operate as a standalone repeater, or as a member of a multi-site system (under the supervision of a DMR conventional node).
1.4 Licences Some operational functions of the base station are controlled by licences. These functions will not work unless you purchase the appropriate feature licence and enable the feature set controlled by that licence. Regardless of which software application you have configured on the TB7300, you can add and remove both P25/AS-IP and DMR/MPT licenses. Note that only licenses associated with your currently configured application will be enabled.
1.4.2 Feature Licences The following section lists each of the available feature licences for both P25/AS-IP and DMR/MPT.

1.5 Theory of Operation The 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. Figure 1.
1.5.1 Signal Paths The following figures provide an overview of signal paths within the control boards for both software applications: Digital P25 signals from the receive RF interface pass through the digital receiver and P25 modem to the control software in the control processor. The control software passes the signal through the Ethernet interface to the site controller, to the console gateway (conventional networks), or for a satellite, to the central voter in a simulcast system.
1.5.2 Online and Offline Modes The 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 is in service and performs its normal functions of transmitting and receiving radio signals. Offline Mode Offline mode allows a maintenance engineer to carry out tasks that can not be done while the base station is in service, such as activating firmware or running diagnostic tests. 1.5.

4 Connecting to the Base Station The web browser on your PC provides a window into the TB7300 base station. Use it to connect to the base station so that you can monitor, configure, diagnose, and calibrate it (if required). This section describes the following: ■ Connecting to the base station, including initially setting things up. ■ Working with base station web pages. ■ Carrying out basic tasks. This section provides an overview of some aspects of the web interface.
4.2 Connecting Your PC to the Base Station You connect to a base station using your web browser. Using multiple browser windows or tabs, you can view more than one base station and more than one page of any base station at once. Base stations have a webbased interface that provides the pages you view. Up to ten users may be logged in to a base station at once. When loading the web user interface with Internet Explorer, the web page may go blank. To fix this, refresh the page with the ‘F5’ key.
and usernames securely and do not lose them. They may be needed by Tait support personnel if assistance is required. Tait cannot retrieve forgotten passwords. 4.2.2 Setting the IP Address Before the base station is installed on site, you need to provide it with its proper IP address. Make sure that you do not lose this address. 1. Select Identity > Identity > Network. 2. Enter the required details in the Change network identity area and click Save.
Base stations leave the factory with default IP address: 192.168.1.2, Subnet mask: 255.255.255.0. If your base station will still not connect to your PC, contact your local Tait dealer. You may need to temporarily disconnect a networked PC from its LAN in order to establish a direct connection with the base station. A physical connection is needed as well as an alternate or temporary IP address and subnet mask. 4.2.
4.2.6 Finding a Lost or Forgotten IP Address Use the following procedure if an IP address has been lost or forgotten. 4.2.7 1. Connect your PC to the serial port on the back of the base station. 2.

4.4 Basic Tasks 4.4.1 User Settings Click on your user name in the top right corner of the page to change your password. Note that this information is stored in the base station, not in your browser. 4.4.2 Taking the Base Station Offline You may need to take the base station offline in order to carry out diagnostic tests or to take it out of service if a fault develops. 4.4.3 1. Click Mode on the status bar (or Select Tools > Tools > Base Station). 2. Under Control, select Offline.
4.4.4 Channels Working with Configuration Files To see all channels associated with both P25/AS-IP and DMR/MPT, go to Configure > Base Station > Channels. To make them easily recognizable, the licenses within this table are prefixed with their specific software application (P25/AS-IP or DMR/ MPT). If you attempt to go online with a channel that is invalid for the software application you are currently using, an alarm will activate (Monitor > Alarms).
Managing Configuration Files Transferring Files Specific software application configurations can be transferred between base stations without overwriting identity information. Configuration It is important to note that configuration items such as the ‘Network Access Code (NAC)’, (air-interface specific to the P25 channel) may not be visible on the web user interface when running its software application equivalent. However, its configuration is still preserved in the database.
Tait recommends that you download these configurations and store them on your PC as a backup before altering and saving any of your own configuration settings. You can also generate a report containing all the base station’s configuration settings relevant to the current application software (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.
The table below provides a summary of where to configure transmit or marshaling delay: Channel type Configured value Single base station, P25 (Phase 1) Configure > Network Interfaces > P25 Network Single base station, AS-IP Configure > Network Interfaces > AS-IP Network Simulcast channel, P25 (Phase 1) Configure > Channel Group [name] > Synchronized – network > Fixed duration Non-simulcast voted channel, P25 (Phase 1) Configure > Channel Group [name] > Unsynchronized local Tx delay Single base sta
Custom alarms provide a warning 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. 4.4.
when running that specific software. For more information, please see the base station help. The TB7300 can store two complete application packages in two distinct slots, one of which is active at any time. This is useful for switching between software applications (e.g. P25/AS-IP to DMR/MPT). Switching Application Packages To switch between one software application package to another, you must first activate the software in the inactive slot.
4.4.13 SNMP Network Management Tait base stations provide Management Information Bases (MIBs), to allow network management using SNMP. The Windows MSI installer includes Tait defined MIBs (look for a folder labeled MIBs under Tait Applications in the Windows Start menu), and they are also published on the Tait Technical support website: http:// support.taitradio.com/home The following table summarises the base station MIB files and indicates with hardware and software application they apply to.
5 Installation This 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. 5.1 Before You Begin 5.1.1 Equipment Security The security of your base station equipment is a high priority.
5.1.3 Equipment Ventilation Always ensure there is adequate ventilation around the base station (refer to “Cabinet and Rack Ventilation” on page 47). Notice Do not operate equipment in a sealed cabinet. The ambient temperature must stay within the specified range. We recommend strongly that you ensure the cooling airflow is not restricted. Notice The cooling fans are mounted behind the front panel.
Figure 5.
5.2 Unpacking the Equipment Unpacking the Base Station Disposal of Packaging The base station is packed in a strong corrugated cardboard carton with top and bottom cushions. 1. Cut the tape securing the flaps at the top of the carton and fold them flat against the sides. 2. Rotate the carton carefully onto its side and then onto its top, ensuring that none of the flaps are trapped underneath. 3. Slide the carton upwards over the cushions and lift it away.
5.3 Identifying the Equipment You can identify the model and hardware configuration of the TB7300 by referring to the product code printed on a label at the rear of the base station. The meaning of each character in the product code is explained in the table below. This explanation of product codes is not intended to suggest that any combination of features is necessarily available in any one product.
5.4 Initial Setting Up Before putting the base station into service, you may want to carry out some basic functional testing, configuration, and tuning (if required). This section provides an overview of these procedures: 5.4.
5.4.2 Working with Configurations The Web UI page under Tools > Files > Configuration allows you to manage your base station configuration. The base station can store up to 10 configurations internally. New configurations are created on the base station and uploaded to your PC. They can also be transferred from one base station to another, and can be transferred from one software application to another. It is important to note that not all configuration values apply to both software applications e.g.
When transferring configuration values between base stations, or from one software application to another, all configuration values are preserved. To copy configurations between base stations, you can download the configuration file from the source base station, then upload and restore this to a new base station. ■ Restore a configuration: Makes the selected configuration active. ■ Download a configuration: Copies the selected configuration to your computer so that you can store it.
5.4.3 Customizing the Configuration The following steps provide an overview of the process used to configure the base station with the settings it needs. Refer to the Help for more detailed information. 1. Log in to the base station (refer to “Connecting Your PC to the Base Station” on page 29 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: 3.
5.4.4 Restricted Port Numbers Certain configuration settings in the base station’s web interface require you to enter a port number (for example, the trunking interface). The following two ranges of port numbers are unavailable for use with the base station: Restricted Port Numbers 5.4.5 Details 0 – 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.
5.4.6 Tuning the Receiver Before 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.
Figure 5.
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 “Local Connection to a Base Station” on page 30. 3. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the RF input.
5.5 Installing the Base Station on Site 5.5.1 Base Stations for Trunked Systems When installing base stations that are part of a trunked system, it is important to observe good site engineering rules. This is especially true when the channels are combined into a single antenna. If 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.
5.6 Mounting the Base Station Figure 5.3 1. Fit the base station into the cabinet or rack and secure it firmly with an M6 (or 0.25in if using the imperial system) screw, flat and spring washer in each of the four main mounting holes b, as shown in Figure 5.3 on page 60. 2. The base station can be wall-mounted by rotating the front mounting brackets and fitting the optional rear brackets (TBBA03-01).
5.6.1 Mounting and Support Kits For TB7300 mounted and support operation, Tait offers the following kits for order: Item Number 5.
5.7.2 Connecting DC Power The base station is designed to accept a nominal 13.8V DC, with negative ground. Notice Any mains power supply used to power the base station is required to meet the isolation separation for reinforced insulation of 3000Vrms or 4242VDC. The DC power connector at the rear of the base station is a heavy-duty M4 screw terminal connector suitable for many forms of connection. Pin Signal Name Signal Type 1 ground input 2 13.
5.7.3 Connecting RF Notice Do not remove the load from the base station while it is transmitting as this may damage the PA output stage. Before disconnecting RF cables, put the base station into ‘Offline’ mode to prevent any transmissions. The RF input to the base station is via the marked BNC connector on the rear panel. The RF output is via the N-type connector on the rear panel (refer to Figure 5.4 on page 61). Cables and antennas should be of high quality.
5.7.4 Connecting an External Frequency Reference An external reference frequency is not normally required for B band. However, an external reference can be used when you need to maximize the range of the base station. The external reference frequency can be 10MHz or 12.8MHz, with an input level of 300mVpp to 5V pp. The stability of this reference should be better than 100 parts per billion. The base station automatically detects the frequency of the external reference and configures itself accordingly.
5.7.5 Connecting a 1PPS Source A 1PPS signal is required for simulcast base stations. Use a 50Ω coaxial cable (RG58 or RG223) to connect the source to the base station’s 1PPS input. You can daisy-chain up to eight base stations using T-junctions. We recommend that the cable length between the first and last load is kept to a minimum. This will reduce any propagation variation between base stations. The maximum overall cable length is 30m.
5.7.6 Ethernet Connection The RJ-45 socket on the reciter’s rear panel provides the 10 BASE-T or 100 BASE-T Ethernet connection to the other devices in the network. Use a Cat-5 cable to connect this socket to the Tait Network via a router or switch. The Web UI allows you to set the Ethernet port speed auto-negotiation to 10/100 Mbit/s or to negotiate a maximum 10 Mbit/s. Tait recommends that you keep the port speed at the factory default setting of 10 Mbit/s.
5.7.7 Connecting General Purpose Inputs and Outputs General purpose inputs and outputs are connected via the DB-25 connector on the rear panel of the base station.
■ 5.7.8 There is significant distance between connected equipment, and voltage transients could cause equipment damage Setting Up Simplex Operation Simplex operation allows the base station to use one antenna to either transmit or receive, so the base station cannot transmit and receive at the same time. A coaxial relay switches an antenna between base station receive and transmit automatically. In single frequency simplex, only one physical radio frequency is used.
6 Maintenance The base station is designed to be very reliable and should require little maintenance. However, performing regular checks will prolong the life of the equipment and prevent problems from happening. It is beyond the scope of this manual to list every check that you should perform on your base station. The type and frequency of maintenance checks will depend on the location and type of your system.
7 Troubleshooting Check that all front and rear connectors and cables are in place, and that power switches are on. If problems persist, contact your regional Tait office. Notice The TB7300 cannot be serviced in the field. It must be returned to your regional Tait office for repair.

Appendix B– Installing the Firmware Package 1.1 Mongoose Installation Package The installation procedure copies files into a folder and adds items to the Windows Start menu (Start > Programs > Tait Applications > TB93001). 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.
1.2.1 Setting up a Temporary Package Server If 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 > TB9300 > 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.
