1 Description

The Tait TB9300 base station is a robust state-of-the-art digital fixed station that combines Tait’s proven strengths in reliability, high performance and modular design 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 TB9300 are scalable in both size and functionality.

The TB9300 can also operate as a simple, conventional analog repeater with CTCSS

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.

12 Description TB9300 Installation and Operation Manual

1.1 Features

The 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.

■ An integrated wiring solution is provided for the system control bus and

DC power connections to each module in the subrack.

■ Reciters (receiver/exciter modules) can be replaced without affecting

the operation of other reciters in the same subrack.

■ Rugged construction with generous heatsinks and fan-forced cooling

for continuous operation from –22°F to +140°F (–30° C to +60°C).

TB9300 Installation and Operation Manual Description 13 © Tait Limited March 2016

1.2 Modules

The base station consists of a subrack with up to two physical transmit/ receive channels.

The single PMU (power management unit) supplies and manages power to the whole subrack (refer to “Theory of Operation” on page 22). One reciter and one PA (power amplifier) are needed for each physical transmit/receive channel. There is also a front panel with user controls and fans. The modules are interconnected at the front of the subrack. External connections to the modules are located at the rear.

Modules come in different variants depending, for example, on the RF band or the supply voltage.

Each module is inserted into the 4U subrack from the front and is secured at the front with a metal clamp. Both clamp and module are easily removed for rapid module replacement. The modules are secured laterally with plastic guides that clip into the top and bottom of the subrack. These guides can be easily repositioned to change the configuration of a subrack. The heavier modules are also secured laterally by metal tabs at the rear of the subrack.

The following provides a brief description of the available modules.

Subrack The 4U subrack is made of passivated steel and is designed to fit into a

standard 19 inch rack or cabinet. The subrack is fitted with an interconnect board that connects the system control bus and power to the modules and front panel. The position of a module in the subrack is defined by the socket on the subrack interconnect board to which the module is connected by the system control bus.

14 Description TB9300 Installation and Operation Manual

Front Panel

The front panel is mounted onto the subrack with two quick-release fasteners. It incorporates the indicator LEDs, four-line LCD display, user controls, ambient temperature sensor and cooling fans.

The indicator LEDS allow some monitoring of the operational status of the base station. The user controls and display allow the technician to configure the IP address of each module. Refer to “Front Panel” on page 42 for more information.

The microphone input and speaker are not used in this release of the TB9300.

Reciter The reciter module comprises the

receiver, exciter and digital control circuitry. The reciter provides the Ethernet interface and system inputs and outputs.

TB9300 Installation and Operation Manual Description 15 © Tait Limited March 2016

Power Amplifier

The PA amplifies the RF output from the reciter and is available in 50W and 100W models.

The 50W model mounts vertically in the subrack, while the 100W model mounts horizontally as it has a wider heatsink. The 100W PA is also fitted with an airflow duct.

Both models are designed to operate on the 28VDC output provided by the PMU.

Power Management Unit

The PMU provides the 28VDC power supply for the modules in the subrack. It can operate on 120/230VAC 50/60 Hz nominal, and 12, 24 or 48VDC nominal. The input voltage can be AC, DC, or both AC and DC, depending on the model. The PMU also has an auxiliary DC output of 13.65VDC, 27.3VDC, or

54.6VDC, depending on the model.

1.3 Mechanical Assembly

This section illustrates the main mechanical components of the base station.

Figure 1.1 below shows the configuration for a typical dual 50W base

station. The subrack has six slots, numbered from right to left as viewed from the front of the subrack. The PMU occupies slots 5 and 6, with the reciters in slots 1 and 2. The two PAs are mounted vertically in slots 3 and 4 with the heatsinks facing each other. The airflow separator between the PAs helps to direct the cooling airflow evenly through each heatsink. The PMU and each pair of reciters and PAs have their own cooling fans.

The front panel can be easily removed from the subrack by undoing two quick-release fasteners. Refer to “Replacing Modules” on page 103 for more details.

1.5 Applications

The TB9300 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 TB9300 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 CTCSS

subaudible signaling

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.

TB9300 Installation and Operation Manual Description 21 © Tait Limited March 2016

1.6 Licenses

Some 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). Tait sells three types of node: Full, 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 Full (TBAS300)

A base station with this license can accept connections from any node/ 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 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 Full, 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.

1. The base station itself can act as a DMR trunking controller, but with limited functionality. The base station is then said to be a standalone node.

22 Description TB9300 Installation and Operation Manual

1.7 Theory of Operation

The reciter receives RF signals from its RF input and sends RF from its RF output to the PA, along with a PA key signal. The reciter also receives signals from, and sends signals to, the system interface, the Ethernet interface, and the front panel (see Figure 1.4).

A system control bus interconnects the modules and carries alarm and control signaling between the reciter and the other modules (refer to

“Intermodule Communications” on page 25 for more details).

The Ethernet interface carries voice over IP and also allows maintainer access via a web browser.

The reciter carries out signal processing and has overall control of the base station. Its circuit boards are shown in Figure 1.5.

The receiver board contains all the receiver circuitry, while the exciter circuitry is located on the transmit forward board.

The reciter control board converts information between analog and digital and controls the maintainer’s access via the front panel. 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.

1.7.1 Signal Paths

Figure 1.6 gives an overview of signal paths within the reciter.

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.

1.7.2 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 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. However, the front panel is still operational and can be used in the normal way.

1.7.3 Intermodule Communications

A system control bus and a subrack interconnect board link the modules in the subrack and carry alarm and control signaling between the reciter and the other modules, as shown in Figure 1.7.

Specific configuration settings for dual base stations are described in

“Recommended Configuration Settings” on page 80.

1.7.4 Power Management and Distribution

The PMU manages the supply of power to ensure uninterrupted operation of the base station. A range of parameters is monitored and these can trigger alarms that are sent to the reciter. Alarms can be monitored via the web interface and reported via SNMP traps; they are also recorded in the reciter’s internal log file.

AC to DC Changeover

When the PMU has an AC and a DC module, the base station can be powered by either the AC (mains) or the DC (battery) supply. The base station will default to the AC supply if both supplies are provided. If the AC supply becomes unavailable, a seamless changeover from the AC to DC supply takes place, providing that the battery voltage is above the configured minimum startup voltage. You can use a web browser to check whether the base station is running on battery or mains power.

DC Operation When the base station is running off the DC supply and the battery voltage

falls below the configured minimum, the base station will enter battery protection mode to protect the battery and base station equipment. The standby power supply card maintains the power to the PMU microprocessor, while the rest of the PMU is shut down. When the battery voltage rises to the configured startup setting, power is resumed to the DC supply. Refer to “PMU Operation on DC Input” on page 28 for more detailed information.

Auxiliary Power Control

The output from the auxiliary power supply board can be used to power other site equipment. The maximum output is 40W.

Distribution Figure 1.8 shows how power is distributed to modules in the subrack. The

28VDC output from the PMU is fed directly to the PA in a single base station, or directly to PA 1 in a dual base station, and to the other modules via the subrack interconnect board. Power to the reciters and front panel is current-limited by self-resetting fuses on the subrack board.

The AC converter has a series switch which breaks the phase input to the converter. The DC input, however, has much higher current ratings. Its switch does not disconnect power from the DC converter itself, but disables the converter by switching off its control circuitry.

The outputs from both the AC and DC high power converters are added together and fed to the modules via the high-current outputs. The auxiliary output is also tapped off this summed output.

1.7.5 PMU Operation on DC Input

The operation of the PMU on DC input is controlled by three sets of parameters:

■ user-programmable alarms

■ user-programmable startup and shutdown limits

■ battery protection limits

The voltage range for each of these parameters is provided in Table 1.1 on

page 29. Figure 1.9 on page 30 illustrates how these parameters interact,

and how they control the operation of the PMU over a range of DC input voltages.

Alarms User-programmable alarms can be set for low or high battery voltage

(Configure > Alarms > Thresholds). The alarms will be triggered when the set voltage levels are reached. These limits are subject to the tolerances of the battery protection circuitry, as stated in “Battery Protection (Fail-safe) Limits” in Table 1.1.

Startup and Shutdown Limits

The user-programmable startup and shutdown limits allow for adjustable startup and shutdown voltages (Configure > Base Station > Miscellaneous). These limits can be adjusted for different numbers of battery cells, or for the particular requirements of the base station operation. Once the limits are reached, the PMU will shut down. These limits are subject to the tolerances of the battery protection circuitry, as stated in “Battery Protection (Fail-safe) Limits” in Table 1.1.

Notice It is possible to set the startup voltage of the base station below the nominal voltage of the battery. Continuing to use a battery for extended periods when it is below its nominal voltage will severely shorten its service life. For more information on battery management, we recommend that you consult the battery manufacturer.

Battery Protection Limits

The battery protection limits are set in hardware at the factory, and cannot be adjusted by the user. These limits will not be reached under normal operation conditions, but are provided as “fail-safe” measures to protect the battery from deep discharge. They also remove the need for low-voltage disconnect modules.
