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 CTCSS1subaudible 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.

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).

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.

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 50/60Hz 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 103 for
more details.

Figure 1.2 below shows the configuration for a typical single 50W base
station. The PMU again occupies slots 5 and 6, with the reciter in slot 1 and
the PA in slot 3. The single PA is mounted vertically with the heatsink
facing the center of the subrack. This positions the cooling fins directly
behind the fan. The airflow separator is fitted directly beside the PA to help
direct the cooling airflow through the heatsink.

Figure 1.3 below shows the configuration for a typical 100 W base station.
The PMU occupies slots 5 and 6, with the PA directly beside it in slots 3
and 4. The reciter occupies slot 1. Unlike the 50W PAs, the 100W PA is
mounted horizontally with the heatsink facing upwards. It is also fitted with
an airflow duct to channel the airflow from the cooling fan through the
heatsink fins.

1.4 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.
In Brazil, for K and L bands, the TB9300 is considered to be configured as
a base station with retransmission of receive frequencies.
Frequency
Identification Frequency Band and Sub-band 50W 100W
B band B2 = 136MHz to 156MHz
B3 = 148MHz to 174MHz ✓✓
G band G4 = 330MHz to 380MHz ✓
H band H1 = 400MHz to 440MHz
H2 = 440MHz to 480MHz
H3 = 470MHz to 520MHz ✓✓
HC = 400MHz to 440MHz (receive)
HC = 440MHz to 480MHz (transmit) ✓
K band K4 = 762MHz to 870MHza
a. The actual frequency coverage in this band is:
Transmit: 762MHz to 776MHz, and 850MHz to 870MHz
Receive: 792MHz to 824MHz
✓✓
L band L2 = 896MHz to 902MHz (receive)
L2 = 927MHz to 941MHz (transmit) ✓

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 CTCSS1
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.
