 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 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.

 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.

 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.

50W PA 100W PA

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

Power Management The PMU provides the 28VDC

Unit 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.

 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.

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 ✓ ✓

L band L2 = 896MHz to 902MHz (receive)

✓
L2 = 927MHz to 941MHz (transmit)

a. The actual frequency coverage in this band is:

Transmit: 762MHz to 776MHz, and 850MHz to 870MHz
Receive: 792MHz to 824MHz

In Brazil, for K and L bands, the TB9300 is considered to be configured as

a base station with retransmission of receive frequencies.

 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.

1. Private Line (PL).

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 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 A base station with this license can accept connections from any node/
(TBAS300) 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 A base station with this license can accept connections from any Express
Express node/standalone node or Access standalone node. In single-site trunking
(TBAS302)
and fallback modes, this license entitles a standalone node to control a
single site of up to 20 physical channels.

DMR Trunking A base station with this license can accept connections only from an Access
Access standalone node. This license entitles a standalone node to control a single
(TBAS303)
site of up to four physical channels.

DMR Conventional A base station with this license can operate in a Tait DMR Tier 2
(TBAS304) 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 A base station with this license can operate as an analog conventional
(TBAS301) repeater.

1. The base station itself can act as a DMR trunking controller, but with lim-
ited 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 25 for more details).

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

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.

Reciter 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.

1.7.2 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 When the PMU has an AC and a DC module, the base station can be
Changeover 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 The output from the auxiliary power supply board can be used to power
Control 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 The user-programmable startup and shutdown limits allow for adjustable
Shutdown Limits 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 The battery protection limits are set in hardware at the factory, and cannot
Limits 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.

 1.7.6 Front Panel Fans

The front panel is equipped with three fans. Fan 1 is for the reciters, fan 2
is for the PAs, and fan 3 is for the PMU. Front panel fans do not operate
continuously, but are switched on and off as needed by their associated
module. In a dual base station either PA or reciter can turn on its fan. The
reciter in slot 1can also carry out a fan test on all three fans.

Front panel fans are 3-wire fans (power, ground, and rotation detect). The
reciter can monitor whether the fans are rotating and generate an alarm if
the fan fails.

The fans turn on for a few seconds when the base station is powered up, and
also after the front panel is refitted to a base station which is powered up.

Configuring Fan The operation of the PA fan is configurable via the web interface; you can
Control specify the threshold temperature at which the fan will be turned on, and
set the fan to operate only when the PA is transmitting.

The PMU fan has fixed on/off thresholds and a defined set of duty cycles
based on the PMU temperature and load current, as described in the
following table.

PMU Temperature Current Fan Duty Cycle

<149°F (65°C) <4A always off

4A–6A 2 minutes on, 8 minutes off
6A–8A 2 minutes on, 5 minutes off
8A–12A 3 minutes on, 3 minutes off

 2.1 Personal Safety

2.1.1 Unpacking and Moving the Equipment

To prevent personal injury and equipment damage, we recommend that two

people unpack and move the equipment.

Caution A subrack complete with modules can weigh up to 62lb

(28kg), or up to 66lb (30kg) complete with packaging. We recommend
that you have another person help you unpack and move the equipment.
The TBAA03-16 carrying handles will make it easier to move the
equipment once it has been unpacked. If necessary, remove the modules
from the subrack before moving it (refer to “Replacing Modules” on
page 103). In all cases follow safe lifting practices.

2.1.2 Lethal Voltages

Warning The PMU contains voltages that may be lethal. Refer

to the ratings label on the rear of the module.

The equipment must be installed so that the rear of the PMU is located in a
service access area which is accessible only by qualified personnel. The
PMU must be connected to the mains supply source by qualified personnel
in accordance with local and national regulations.

Disconnect the mains IEC connector and wait for five minutes for the
internal voltages to self-discharge before dismantling. The AC power
on/off switch does not isolate the PMU from the mains. It breaks only
the phase circuit, not the neutral.

The PMU should be serviced only by qualified technicians. There are no

user-replaceable parts inside. If the PMU is damaged and does not function
properly, stop the module safely and contact your regional Tait office
immediately.

All servicing should be carried out only when the PMU is powered through
a mains isolating transformer of sufficient rating.

 2.1.7 Proximity to RF Transmissions / A proximité des émissions RF

To comply with the RF Field Limits for Devices Used by the General
Public for (Uncontrolled Environment)a, a safe separation distance of at
least 12 feet (3.6 metres) from the antenna system should be maintained.

This figure is calculated for a typical installation, employing one 100W

base station transmitter. Other configurations, including installations at
multi-transmitter sites, must be installed so that they comply with the
relevant RF exposure standards.

2.2.1 Installation and Servicing Personnel

The equipment should be installed and serviced only by qualified

personnel.

2.2.2 Preventing Damage to the PA

The base station has been designed to operate safely under a wide range of
antenna loading conditions. Transmitting into a low VSWR will maximize
the power delivered to the antenna.

Notice Do not remove the load from the PA while it is transmitting.

Load transients (switching or removing the load) can damage the PA output
stage. See “Connecting RF” on page 95 for recommendations.

2.2.3 ESD Precautions

Notice This equipment contains devices which are susceptible to

damage from static charges. You must handle these devices carefully
and according to the procedures described in the manufacturers’ data
books.

We recommend you purchase an antistatic bench kit from a reputable

manufacturer and install and test it according to the manufacturer’s
instructions. Figure 2.1 shows a typical antistatic bench set-up.

You can obtain further information on antistatic precautions and the

dangers of electrostatic discharge (ESD) from standards such as ANSI/

 2.2.4 Anti-tampering Devices

All network elements should be physically secured, where possible. This

includes the use of locked cabinets and the use of seals on connectors.

All network connectors should be sealed with the stick-on type of seal. The
purpose of the seals is to detect unauthorized tampering. The seal should
reveal if any of the connectors have been unplugged or if any unauthorized
equipment has been plugged in.

The seals must be difficult to remove without breaking, and must bridge
between the cable and equipment side (plug and socket) of the connection.

Seals must cover any unused network sockets. This includes the Ethernet
connector on the rear panel, any spare switch ports, and the console port on
the router and switch.

The seals must be difficult to reproduce. A sticker initialed or signed by the

technician should satisfy this.
Seals must be replaced if they need to be disturbed during maintenance.

2.3 Environmental Conditions

2.3.1 Operating Temperature Range

The operating temperature range of the equipment is –22°F to +140°F

(–30°C to +60°C) ambient temperature. Ambient temperature is defined as
the temperature of the air at the intake to the cooling fans.

2.3.2 Humidity

The humidity should not exceed 95% relative humidity through the
specified operating temperature range.

2.3.3 Dust and Dirt

For uncontrolled environments, the level of airborne particulates must not

exceed 100µg/m3.

 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. A quick way
to set the base station’s IP address is to use the front panel, as described
below.

Notice If access to this menu on the front panel has been disabled,
log in to the base station and set the IP address using the web interface
(Identity > Identity > Network Identity).

1. Use the front panel display to enter the IP address, subnet mask and
gateway specified for this base station by the IP addressing plan for
the network. From the base station menu select Modules > Reciter 1
(or 2) > Edit Reciter 1 (or 2) Address. If the home screen is showing,
press an arrow key, a scroll key or OK to clear it.

Notice In this screen each octet in the address lines has provision for
three characters. If an octet in the address has less than three characters,
enter one or two leading zeroes so that each position is filled, even
though the zeroes are not part of the address. For example, enter
172.25.163.47 as 172.025.163.047. Leading zeroes are removed when
the address is programmed into the base station.

2. Set each address as described below. Use the left and right arrow
keys to move the cursor across each line in the Addresses screen.

 4.2.3 Security Certificates

You can upload your own security certificates to the base station (Tools >
Settings > Web certificate). If you have installed and configured the
appropriate Certification Authority software, you can issue security
certificates for all base stations. After uploading the certificates to the base
stations, you can configure all maintainers’ web browsers to accept
security certificates from your own Certification Authority.

Before you have uploaded a security certificate to the base station, it

will raise a security warning when your browser connects to it for the
first time. The base station creates a self-signed certificate when the
reciter’s firmware is installed. Your browser raises a security warning
because the security certificate was not issued by a trusted Certification
Authority. The browser has a way of letting you override or bypass the
security warning.

 4.2.5 Troubleshooting Connection Problems

If the attempt to connect to a base station failed, consider these possible

causes.

1. Your PC is part of your organization’s LAN and does not belong to

the same subnet as the base station. Give the PC a suitable IP address
and subnet mask as described in “Connecting a Networked PC to a
Base Station” on page 56.

2. You are attempting to connect to the wrong IP address. Check that

the IP address is correct.

Notice You can quickly check the base station’s IP address via the
front panel, as long as access to this menu has not been disabled.

3. The link to the base station is down. Use ping to check.

4. You may have to bypass the proxy in your organization’s LAN to

access the Tait Network. Ask your system administrator to give you
access.

5. JavaScript may be disabled in your browser. If JavaScript is

disabled, your browser will be unable to connect to the base station.
Note that modern browsers normally have JavaScript enabled by
default.

4.2.6 Finding a Lost or Forgotten IP Address

Use the following procedure if an IP address has been lost or forgotten.

1. Mount the reciter in a TB9300 subrack and fit the front panel. Power
up the subrack.

2. On the front panel display select Modules > Reciter 1 (or 2) > View
Reciter 1 (or 2) Address.

 4.2.7 Setting Up Authentication

Connections to the base station can be authenticated by a remote

(i.e. centralized) service (Tools > Settings > Authentication). Two remote
authentication protocols are supported: LDAP and RADIUS.

Notice Only people experienced with the AAA architecture and

authentication protocols should make changes on this page.

Moving logins to a centralized server can provide enhanced security for a

number of reasons, such as:
■ less work is required to manage password-controlled access to all base
stations in a network; you no longer need to change the password in
each base station individually
■ previously used passwords may be excluded from re-use
■ access can be denied after a set number of incorrect passwords is
entered
■ passwords can be set to expire on a certain date
■ remote access to base stations can be globally enabled and disabled as
required for technical staff during the commissioning process.

Once the centralized server logins are set up, we recommend that only one
local administrator login is left on the base station for emergency use
(e.g. when the connection to the server is lost). The password for this
emergency login should be kept secret.

Notice Unless they are deleted, any local logins left on the base sta-
tion will still work and have priority over remote logins.

particular role in the network. Some settings, such as those for the trunking
interface (Configure > Network Interfaces > Network), always apply.

Others are channel-based so that they can be dynamically changed. To view

these, you first need to know the channel that the base station is operating

 4.4.4 Working with Configuration Files

At 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 Alarms

Each 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.

4.4.6 Disabling the Front Panel Keypad

You can disable the front panel keypad to prevent access to the base station
via the front panel menus. Select Configure > Base Station > Miscellaneous
and in the Front Panel area clear the Keypad enabled check box.

 Notice If you disable the front panel keypad, you cannot use it to find
out the base station’s IP address. Make sure that you store the IP address
securely and do not lose it.

4.4.7 Preparing to Download Firmware

New 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 is provided on the product CD, and can
also be downloaded as a zip file from the Tait support website.

This procedure describes using the Mongoose web server.

Installing the The installation procedure copies files into a folder and adds items to the
Firmware Package Windows Start menu (Start > Programs > Tait Applications > TB9300).
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.

If you have a product CD:

1. Insert the product CD into the CD drive of the package server

computer.

2. If the CD does not autorun, navigate to the CD’s root folder and
double-click TB9300.msi to run the Windows installer.

If you are downloading a base station package zip file:

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.

 Setting Up a Central It is beyond the scope of this manual to describe the exact procedure for
Package Server 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 If you want to use a laptop as a temporary package server, you can
Temporary Package temporarily override the package server IP address and port in each base
Server
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. 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.

 5 Installation

This chapter provides information on the site requirements for your

TB9300 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 TB9300 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. If the site is
not fully secure, the base station should at least be locked in a secure,
ventilated cabinet to prevent unauthorized access.

5.1.2 Grounding and Lightning Protection

Electrical Ground The base station modules are grounded by physical contact between the
module case and the subrack. To ensure a good ground connection you
must tighten each module retaining clamp securely (refer to “Final
Reassembly” on page 114 for the correct torque).

A threaded grounding connector is provided on the rear of the subrack for

connection to the site ground point (refer to “Connecting Up the Base
Station” on page 91 for more details).

Lightning Ground It is extremely important for the security of the site and its equipment that
you take adequate precautions against lightning strike. Because it is outside
the scope of this manual to provide comprehensive information on this
subject, we recommend that you conform to your country’s standards
organization or regulatory body.

5.1.3 Equipment Ventilation

Always ensure there is adequate ventilation around the base station (refer
to “Cabinet and Rack Ventilation” on page 71).

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 on the front panel and will only
operate when the panel is fitted correctly to the front of the subrack. To
ensure adequate airflow through the base station, do not operate it for
more than a few minutes with the front panel removed (e.g. for servicing
purposes).

5.1.4 Ambient Temperature Sensor

The ambient temperature reading for the base station is provided by the
temperature sensor located on the front panel circuit board.

70 Installation TB9300 Installation and Operation Manual

© Tait Limited March 2016

Downloaded from www.Manualslib.com manuals search engine

 5.1.5 Cabinet and Rack Ventilation

The cooling airflow for the base station enters through the front panel and
exits at the rear of the subrack. 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. Any space at the front of the cabinet
not occupied by equipment should be covered by a blanking panel. Refer
to Figure 5.1 on page 72.

To allow enough cooling airflow through a cabinet-mounted base station,

we recommend the following:
■ an area of at least 23in2 (150cm2) of unrestricted ventilation slots or
holes in front of the air intakes for the fans for each subrack; for
example, thirty 0.25x3.3in (6x85mm) slots will allow the
recommended airflow
■ a vent in the top of the cabinet with an area of approximately 23in2
(150cm2) per subrack, or a similar area of ventilation per subrack at the
rear of the cabinet behind each subrack
■ a 2U gap at the top of the cabinet.

Notice 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
+140°F (+60°C).

If you are installing multiple subracks in a cabinet, ensure that there will be
enough cooling airflow through the cabinet after the equipment has been
installed. For example, the recommended maximum number of subracks in
a 38U cabinet is five, as shown in Figure 5.1 on page 72.

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 The base station does not require auxiliary extractor fans mounted in the
Fans top of the cabinet. If your cabinet is already fitted with fans, the following
procedures apply:
■ if there are six or more 4.75in (12cm) fans, each capable of extracting
94.2 ft3 per minute (160m3 per hour), they must run continuously
■ if there are fewer than six fans, you must remove them and ensure the
vent in the top of the cabinet has an area of approximately 23in2
(150cm2) per subrack.

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.

 5.2 Unpacking and Moving the Subrack
The subrack is packed in a strong corrugated cardboard carton with top and
bottom foam cushions. To prevent personal injury and damage to the
equipment, we recommend that two people unpack and move the subrack.
To remove the subrack from the carton, follow the procedure illustrated in
Figure 5.2.

Caution A subrack complete with modules can weigh up to 62lb

(28kg), or up to 66lb (30kg) complete with packaging. We recommend
that you have another person help you unpack and move the equipment.
The TBAA03-16 carrying handles will make it easier to move the
equipment once it has been unpacked. If necessary, remove the modules
from the subrack before moving it (refer to “Replacing Modules” on
page 103). In all cases follow safe lifting practices.

 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:
■ checking that the base station powers up correctly
■ checking the basic functionality of the base station by using the tests
available in the web interface
■ customizing the configuration for the intended installation and
verifying that the configuration is correct
■ changing the root password
■ tuning the base station (if required).

5.4.1 Confirming Operation

Notice Make sure that the RF output is connected to a suitable atten-

uator or dummy load. Do not remove the load while the PA is transmit-
ting as this may damage the PA output stage.

Applying Power 1. Apply power by turning on the PMU.

2. Check that the base station powers up correctly:

■ The front panel display will show “Please wait...” while the base
station starts up (this may take up to two minutes). When the
startup process is complete, the display will show the home
screen.
■ The cooling fans in the front panel will run at full speed for a few
seconds, then run at low speed while the base station starts up,
and then assume standard operation. One or more fans may
operate, depending on the temperature of the modules.

 5.4.2 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 detailed
information.

1. Log in to the base station (refer to “Connecting Your PC to the Base

Station” on page 52 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 minimum battery voltages, fan
control, 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.

5.4.3 Recommended Configuration Settings

In a dual base station only reciter 1 communicates directly with the PMU
and front panel. Therefore the following configuration settings are
recommended for dual base station operation:
■ Disable the “PMU not detected” alarm on base station 2 (Configure >
Alarms > Control > PMU).
■ Disable the “FP not detected” alarm on base station 2 (Configure >
Alarms > Control > Front panel).

 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).

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.

Restricted Port Numbers 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.

12000 – 14999 Reserved for internal use in the base station. Using a
port number in this range could cause the base
station to malfunction.

5.4.5 Changing the Root Password

Notice 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 reciter 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.

 5.4.6 Tuning the Reciter

B-Band 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.

The receiver in the B-band reciter covers one of the following frequency
bands, depending on the model:
■ B2 - 136 to 156MHz
■ B3 - 148 to 174MHz

Each of these bands is split into 2 sub-bands:

■ B2 - 136 to 146MHz and 146 to 156MHz
■ B3 - 148 to 159MHz and 159 to 174MHz

Each sub-band has its own helical filter (shown in Figure 5.3 below) which
is electronically switched in or out of circuit depending on the frequency
programmed into the reciter. The bandwidth of these helical filters is
approximately ±1.5MHz.

Figure 5.3 Identifying the B-band receiver front end helical filters

B2: 146 to 156MHz

B3: 159 to 174MHz

B2: 136 to 146MHz

B3: 148 to 159MHz

To check the RSSI level and tune the receiver front end (if required), follow
these steps.

1. Remove the reciterfrom the subrack and reconnect the system

control bus cable to power up the module.

 2. Log in to the reciter and select Monitor > Interfaces > RF Interface.
For information on connecting directly to the reciter, refer to
“Connecting a Networked PC to a Base Station” on page 56.

3. Feed a signal at the currently tuned receive frequency and at a level

of –80dBm into the reciter’s RF input. Check that the RSSI reading
on the RF Interface page is –80dBm ±1dB. Note this reading.

4. Set the reciter 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 5.3) 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 reciter’s 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 > Reciter >
RSSI).

If you wish to confirm the accuracy of the tuning procedure, carry out a
sensitivity measurement at the new frequency.

 H-Band 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 5MHz 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 H-band reciter covers one of the following frequency
sub-bands, depending on the model:
■ H1 and HC - 400 to 440MHz
■ H2 - 440 to 480MHz
■ H3 - 470 to 520MHz.

Each sub-band uses the same helical filter (shown in Figure 5.4 below).
The bandwidth of the helical filter is approximately ±5MHz.

 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 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 Required

It is beyond the scope of this manual to list every piece of equipment that
an installation technician should carry. However, the following tools are
specifically required for installing the base station:
■ Pozidriv PZ3 screwdriver for the M6 screws used in the DC input
terminals on the PMU; M6 (0.25in) screws are also used to secure the
subrack to the cabinet in factory-assembled systems
■ Pozidriv PZ2 screwdriver for the M4 screws used to secure the module
retaining clamps, and for the fasteners used to secure the front panel to
the subrack
■ 8mm AF spanner for the SMA connectors, and the subrack 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.

 5.5.3 Mounting the Subrack

Caution A subrack complete with modules can weigh up to 62lb

(28kg), or up to 66lb (30kg) complete with packaging. We recommend
that you have another person help you unpack and move the equipment.
The TBAA03-16 carrying handles will make it easier to move the
equipment once it has been unpacked. If necessary, remove the modules
from the subrack before moving it (refer to “Replacing Modules” on
page 103). In all cases follow safe lifting practices.

 Auxiliary Support TBAA03-13 auxiliary support brackets can be fitted to the rear of the
Bracket subrack to provide additional mounting security. Figure 5.7 shows a
standard TBAA03-13 bracket b fitted in a typical Tait cabinet c. If you
are not using the Tait cabinet, you may have to make your own brackets to
suit your installation.

Figure 5.7 Auxiliary support bracket

Notice You must fit the auxiliary support brackets if you intend to
transport a cabinet fitted with a fully built-up base station.

We also recommend that you fit the brackets under the following
conditions:
■ when the installation is in an area prone to earthquakes
■ when third party equipment is installed hard up underneath the base
station subrack.

General Cabling We recommend that you try to route all cables to and from the base station
along the side of the cabinet so the cooling airflow is not restricted.

 DC Power Cabling DC power cables should be well supported so that the terminals on the
PMU and on the ends of the cables do not have to support the full weight
of the cables.

Figure 5.8 shows two recommended methods of securing these cables to

prevent straining either set of terminals.

We recommend that you fit the supplied covers to the DC terminals to

protect against accidental shorts.

 5.6.2 Connecting AC Power

The PMU is designed to accept a mains input of 88 to 264VAC at 45 to

65Hz. A standard 3-wire grounded socket outlet must be used to supply the
AC power. The socket outlet must be installed near the equipment and must
be easily accessible. This outlet should be connected to an AC power
supply capable of providing at least 600W. The requirements of two typical
AC supplies are given in the following table.

 5.6.3 Connecting DC Power

The PMU is designed to accept a nominal 12VDC, 24VDC or 48VDC

input (depending on the model) with negative or positive ground. There is
a minimum DC startup threshold to prevent damaging a battery which has
little capacity left.

You must connect the DC supply from the battery to the PMU via a fuse or
DC-rated circuit breaker with the appropriate rating, as shown in the table
below. The circuit breaker must have a contact separation of 3mm, an
interrupt capacity of 1000A or more, and an inrush current capability of at
least 500A for a minimum of 3.5ms.

Notice The inrush current is not affected by the state of the DC mod-
ule on/off switch on the PMU. This switch does not disconnect power
from the DC converter itself. It disables the converter by switching off
its control circuitry. Even when the DC converter is off, the DC input is
still connected to its power circuitry.

The DC input leads should be of a suitable gauge to ensure less than 0.2V
drop at maximum load over the required length of lead.

a. The actual current consumption of the base station will be lower than these re-
quirements (refer to the Specifications Manual for more information).
b. For a length of 5ft to 6.5ft (1.5m to 2m) (typical).

Terminate and insulate the DC input leads to protect them from

accidentally shorting to the subrack if the PMU is removed before the leads
are disconnected. Protective covers for the DC terminals are supplied with
each PMU. We recommend a screw torque of 18–20lbf·in (2–2.25N·m).

 5.6.4 Connecting the Auxiliary DC Power Output

The PMU can provide an auxiliary DC output from the auxiliary power
supply board. This board is available with an output of 13.65VDC,
27.3VDC, or 54.6VDC (depending on the model), and is current limited to
3A, 1.5A or 750mA respectively. This power supply is permanently on as
soon as the base station has finished powering up, and is available on the
auxiliary output connector on the rear panel.

You can connect multiple auxiliary power supply boards in parallel for
redundancy purposes, or to provide an output greater than 40W. Although
no active current sharing is used, auxiliary boards connected in parallel will
current-share before reaching their power limit. The failure (or switching
off) of one auxiliary board will not load any other paralleled auxiliary
boards in the circuit.

The auxiliary power supply turns off briefly when the PMU restarts
after a firmware upgrade. This interruption may also cause any ancillary
equipment powered from the auxiliary supply to restart. If this is a prob-
lem for your system, we recommend connecting auxiliary power supply
boards in parallel to ensure an uninterrupted power supply for the ancil-
lary equipment.

Auxiliary DC Power Network elements are supplied with a connector, as shown in Figure 5.10.
Output Cabling You can use this to connect the PMU’s auxiliary DC power output to
another device (refer to “PMU Auxiliary DC Output” on page 117 for the
pin allocations).

Contact your regional Tait office for details on the full range of wiring kits
available.

 5.6.5 Connecting RF

Notice Do not remove the load from the PA while it is transmitting

as this may damage the PA output stage. Before disconnecting any RF
cables, put the base station into Offline mode to prevent any transmis-
sions.

The RF input to the base station is via the marked BNC connector on the
rear panel of the reciter. The RF output is via the N-type connector on the
rear panel of the PA (refer to Figure 5.9 on page 91).

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.

Recommendations We recommend the following installation procedures, which should protect

for Installing the PA the PA from damage under all but the most extreme operating conditions.

1. Do not connect the PA directly to the antenna. Fit an isolator or

duplexer between the PA and the load. Fit the isolator as close as pos-
sible to the RF output connector on the PA. Do not connect any
switching equipment between the isolator and the PA, unless the
switch cannot operate while there is RF present (i.e. the base station
is transmitting).

2. Fit a surge suppressor to the antenna cabling where it enters the

building.

3. Inspect all cables and equipment connected to the base station for
defects.

Ice on the antenna, or a broken antenna, is unlikely to cause damage to the

PA.

Explanation The circuit design of the PA protects the circuitry from high VSWR. This
makes it difficult to damage the RF power device by keying the PA into a
mismatched load, or if the load deteriorates over even a short period of time
(milliseconds).

However, it is possible to damage the device if all the following conditions

happen at the same time:
■ there is a step change in the PA load (for example, the load is removed)
■ the PA is transmitting
■ the feed line loss between the PA and the mismatch is <1dB.

The effect of such conditions is variable: some devices will not be

destroyed, and some may fail after repeated load interruptions.

 5.6.6 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. For K4 band, the internal frequency reference
accuracy is inadequate, and an external reference must be used. 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 reciter automatically detects the frequency
of the external reference and configures itself accordingly.

If an external reference is required, enable the external reference “Absent”

alarm (Configure > Alarms > Control).

Use a 50Ω coaxial cable (RG58 or RG223) to connect the external

reference to the base station’s external reference frequency input. You can
daisy-chain up to eight base stations using F-junctions. The maximum
overall cable length is 30m. Terminate the last connection (including single
base stations) with a 50Ω load.

 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. The checks and
procedures listed below can be used as a starting point for your
maintenance schedule.

Performance We suggest you monitor the following operational parameters using the
Checks web interface:
■ VSWR
■ DC input voltage, especially on transmit
■ any temperature alarms.

These basic checks will provide an overview of how well your base station
is operating.

Reciter We recommend that you calibrate the reciter after three months of
operation, and then annually for H-band reciters, or every three years for
B-band reciters. The calibration procedure is described in the Help
(Calibrate > Reciter > Internal reference), and requires a calibrated
frequency generator.

PA There are no special maintenance requirements for the PA.

PMU There are no special maintenance requirements for the PMU. However, we
suggest that you periodically check that the screws on the DC input
terminals are tightened to the recommended torque of 18–20lbf·in
(2–2.25N·m). They may work loose with thermal cycling. Also, if you are
using battery back-up, you should check the batteries regularly in
accordance with the manufacturer’s recommendations.

Ventilation The base station has been designed to have a front-to-back cooling airflow.
We strongly recommend that you periodically check and maintain the
ventilation requirements described in “Equipment Ventilation” on page 70
to ensure a long life and trouble-free operation for your base station. Also
check for a build-up of dust in and around the module heatsink fins, front
panel air intakes, and fan ducts.

 8.1 Saving the Base Station’s Configuration
Before replacing a module in the base station, you should decide whether
you need to save its configuration data. If you are unsure whether you have
a record of the configuration, backup and save the configuration file before
removing any modules. Once you have replaced the module, you will be
able to restore the original configuration to the base station.

If one or more of the modules is faulty, you may be unable to save the
configuration. In this case, you will have to restore the configuration from
a back-up file. Refer to the Help for more information.

 8.8 Final Reassembly
Notice You must refit the correct type of front panel to your base sta-
tion. There are several small but important differences between the front
panel for a 50W base station and the front panel for a 100W base sta-
tion. These differences are in the duct for the PA fan and are described
in the following paragraphs.

50W Front Panel The PA fan duct does not have the cut-outs b required for the 100W PA
RF and DC cables. The break-off tab c will also still be present and will
jam on the system control bus. Do not try to fit this front panel to a 100W
base station or you will damage these cables and possibly the front panel
itself.

100W Front Panel Do not fit this front panel to a 50W base station. The presence of the cut-
outs and absence of the break-off tab will allow air to escape and reduce the
velocity of air directed through the heatsink.

 call A complete exchange of information between two or more parties. A call
requires a receive signal path and a transmit signal path. In conventional
systems, a call is an over, but in trunked systems, a call may be a
conversation, made up of a number of overs.

channel 1. A path through which signals can flow.

2. In the RF domain, a frequency pair (or just a single frequency in a
simplex system). Also called a physical channel in this manual.
3. One of the two timeslots that DMR provides for each radio frequency
(physical channel). Refer to “logical channel”.
4. A set of configuration information that defines the frequency pair and
other related settings (a channel configuration). “Channel” has this
meaning in the web interface.

channel spacing The bandwidth that a channel nominally occupies. If a base station has a
channel spacing of 12.5 kHz, there must be a separation of at least 12.5 kHz
between its operating frequencies and those of any other equipment.

channel table The base station’s database of channel configurations.

CODEC A device which combines analog-to-digital conversion (coding) and

digital-to-analog conversion (decoding).

colour code A marker determining which transmitted signals are gated. Inbound
messages must carry this code to be listened to. The colour code is
configured at the Node Controller. It can prevent interference from other
networks and define private talkgroups.

configuration file Consists of all the configuration settings needed for a base station, stored
as a file.

conventional Systems that do not have centralized management of channel access.

network System operation is entirely controlled by system end users.

CTCSS CTCSS (continuous tone controlled squelch system), also known as PL

(private line), is a type of signaling that uses subaudible tones to segregate
groups of users.

CWID Continuous Wave Identification is a method of automatically identifying

the base station using a Morse code. Continuous wave means transmission
of a signal with a single frequency that is either on or off, as opposed to a
modulated carrier.

DAC Digital-to-Analog Converter. A device for converting a digital signal to an

analog signal that represents the same information.

Standards Institute (ANSI) and responsible for developing
telecommunications and electronics standards in the USA.

EMC Electromagnetic Compatibility. The ability of equipment to operate in its

electromagnetic environment without creating interference with other
devices.

ETSI European Telecommunications Standards Institute. The non-profit

organization responsible for producing European telecommunications
standards.

fallback mode An operational mode of Tait DMR trunked networks. It comes into effect
when the base station loses communication with the trunking node
controller. Fallback mode turns one of the base station’s two logical
channels into a control channel. In this mode the base station functions
almost as an open channel, available to all calls without requiring
authorization.

FCC Federal Communications Commission. The FCC is an independent United

States government agency that regulates interstate and international radio
communications.

Purchasing a license from Tait allows you to enable the feature set which
includes the required functionality.

logical channel One of the two timeslots provided in each TB9300 radio frequency. Each
timeslot can function as a separate logical channel, independent of the other
timeslot. One radio frequency can therefore carry two separate voice or
data streams, one in each timeslot.

mobile station The term used in the ETSI DMR standard documents for a two-way radio
(generally a mobile or a portable radio) conforming to the DMR
specifications.

mute Prevents audio from being passed to the radio’s speaker.

both RF and IF frequencies. A SAW filter uses the piezoelectric effect to
turn the input signal into vibrations that are turned back into electrical
signals in the desired frequency range.

selectivity The ability of a radio receiver to select the wanted signal and reject
unwanted signals on adjacent channels (expressed as a ratio).

sensitivity The sensitivity of a radio receiver is the minimum input signal strength
required to provide a usable signal.
