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 operates as a transceiver in trunked DMR or MPT networks, and as a repeater in DMR or analog conventional networks. In a DMR or MPT trunked network, the TB9300 provides control channel and traffic channel functions, including stand-alone operation in fallback mode.

The TB9300 operates as a simple, conventional analog repeater with CTCSS1 or DCS 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.

The ability of the base station to link stations using standard Internet Protocol communications, and to add features through software options ensures that systems designed with the TB9300 are scalable in both size and functionality.

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.

1.1 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.

■ MPT operation as control channel or traffic channel transceiver in MPT/

IP network including standalone 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).

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 21). 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.

TB9300 Installation and Operation Manual Description 13 © Tait Limited March 2017

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 39

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.

14 Description TB9300 Installation and Operation Manual

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 100 W 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 28 VDC 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 50/60Hz 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 99 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, an MPT-IP 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 an MPT network, the TB9300 operates as a control channel or as a traffic channel. The TB9300 operates with a trunking node or in fallback operation, both of which can be either trunked or conventional.

In analog operation it can operate as a conventional repeater with CTCSS1 or DCS subaudible signaling2.

For more information, refer to the DMR System Manual.

2. Multi-site operation with voice-over-IP connection will be supported in a later release.

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 central voter and satellite licences are alternatives. The base station is fully functional without them.

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.

Analog Air Interface (TBAS301 - Default Licence)

A base station with this license can operate as an MPT transceiver or an analog conventional repeater.

DMR Trunking Full (TBAS300)

A base station with this license can accept connections from any node/ standalone node1. 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. For more information on DMR Trunking Express, see the TB9300 System Manual

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 standalone 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.

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.

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 24 for more details).

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