Description
The Tait TB9400 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 TB9400 operates as a transceiver in Project 25 trunked, trunked
simulcast, and P25 conventional networks. It is capable of either P25 Phase
1 FDMA operation, or 6.25kHz equivalent P25 Phase 2 TDMA operation.
The TB9400 can also operate in an analog conventional simulcast or
non-simulcast multi-site network.
The TB9400 combines industry-leading digital voice quality with rugged
design specifications and intuitive user interfaces. These products are
designed to meet the needs of the public safety and public service sectors.
The ability of the base station to link stations using standard Internet
Protocol communications, and to add features through software options
ensures that P25 systems designed with the TB9400 are scalable in both
size and functionality.
Its Ethernet interface provides built-in network connectivity, allowing the
TB9400 to join with other TB9400 base stations to form a channel group.
This network supports voice-over-IP and remote management of all base
stations via a web browser.

Modules
The base station consists of a subrack with up to two transmit/receive
channels, or up to four receive-only channels.
Receive-only base stations are currently available for operation only on
B3 band (148MHz to 174MHz), H1 band (400MHz to 440MHz), H2
band (440MHz to 480MHz), H3 band (470MHz to 520MHz), and K4
band (762MHz to 870MHz)1.
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 transmit/receive channel.
The PA is not required for a receive-only base station. 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.
1. Refer to “Frequency Bands and Sub-bands” on page 18.

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 base stations have different front panel ducting arrangements
depending on PA type and power. Front panels may not be interchangeable.
The microphone input and speaker are not used in this release of the
TB9400.
Reciter
The reciter module comprises the receiver, exciter and digital control
circuitry. The reciter provides the Ethernet interface and system inputs and
outputs.
Receiver modules (receive-only reciters) are not fitted with the transmit
circuitry or front panel SMA connectors, and are physically unable to
transmit.

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. PAs are not required in a receive-only base station.
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.

Applications
The TB9400 operates in P25 trunked networks (Phase 1 or Phase 2), P25
conventional networks and analog conventional networks. It operates as a
stand-alone repeater/base station, or as part of a channel group, providing
receiver voting and simulcast transmission. All air interfaces and system
types support simulcast operation.
In P25 Phase 2 operation, a single TB9400 base station can provide two
traffic channels, since each radio frequency (physical channel) provides
two logical channels (timeslots). However, it can provide only one control
channel, since control channels are still P25 Phase 1.
In a trunked simulcast network, the transmitters in the channel group are
synchronized and transmit simultaneously on the same frequency. Each
transmitter needs a highly accurate 1PPS pulse and an external frequency
reference, so that it can time transmissions with the required accuracy. Also
required is an NTP source that is derived from the same source as the 1PPS
signal. This will ensure a common timestamp in logs across all units in the
system. An external frequency reference, along with an NTP source and
1PPS signal derived from the same GPS source, are also essential for all
reciters for P25 Phase 2 operation.
In a P25 conventional network, the TB9400 operates as a single or wide
area conventional repeater, with receiver voting and optional simulcast.
Dispatch connection is via the Tait P25 Console Gateway, supporting
conversion between P25 and analog consoles with MDC1200 signalling.
In an analog conventional network it can operate as a repeater with
CTCSS1 or DCS subaudible signaling.
The base station can also operate as part of an analog conventional
simulcast network and is fully IP-connected. The base station also features
an internally integrated voter, and therefore requires no external voter.
The base station can be provided as a receive-only variant in systems that
need sites to enhance the receive coverage. The receiver module in a
receive-only base station is physically unable to transmit.
The base station can be configured for Shared Channel operation, to detect
interference on the uplink, as long as the site controller is compatible.
For more information on these applications, refer to the Help and
appropriate Tait System Manual.

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 listed below are alternatives.
Analog Air Interface
(TBAS041 - Default
Licence)
This is the licence that accompanies the base station. A base station with
this license can operate as a repeater in an analog conventional network.
P25 Common Air
Interface
(TBAS050)
Allows the base station to go into Online mode. Base stations are always
provided with this license.
P25 Trunking
Operation
(TBAS056)
Allows the base station to participate in Trunking Operation. Without this
feature, the base station cannot provide a control or a status connection to
a trunking site controller and it cannot function as a control or traffic
channel.
Digital Fixed Station
Interface (TBAS060)
Allows the base station to integrate with dispatch consoles supporting
DFSI (Digital Fixed Station Interface).
Central Voter
(TBAS061)
P25 and analog. This feature allows a base station to act as a central voter.
Simulcast
(TBAS062)
This feature is required in base stations that have transmitters and belong
to a P25 Phase 1 simulcast or analog simulcast network1. It is also required
in the central voter of a simulcast channel.2
Linear Simulcast
Modulation
(TBAS065)
P25 only. Allows the base station to transmit using the LSM modulation
scheme1. This scheme allows increased site separation in simulcast
networks. Also requires the Simulcast license (TBAS062).
P25 Trunking
Failsoft
(TBAS063)
Allows trunked channels that become isolated from a site controller to
perform simple conventional operation and to interface to a digital dispatch
system. If a trunked channel consists of several base stations in a channel
group, only the central voter (normally the master) needs this license. It is
then able to become the failsoft repeater for that channel group.
1. Not needed for receive-only base stations.
2. The central voter in a simulcast channel needs the respective Phase 1 or
Phase 2 simulcast license. Normally, a transceiver member of a simulcast
channel will have a simulcast license, so this constraint should not be an
issue.
20
Description
TB9400 Installation and Operation Manual

P25 Phase 2
Trunking
(TBAS066)
This feature allows the base station to operate in trunking mode using
two-slot TDMA as defined by the P25 Phase 2 standards.
P25 Phase 2
Simulcast
(TBAS069)
This feature is required in base stations that have transmitters and belong
to a P25 Phase 2 simulcast network1. It is also required in the central voter
of a P25 Phase 2 simulcast channel2. Also requires the P25 Phase 2
Trunking (TBAS066) and Simulcast (TBAS062) licenses. Tait also
recommends adding the Linear Simulcast Modulation (TBAS065) license
as it provides improved RF performance.
IP Networking
Satellite
(TBAS071)
All system types and all air interface types. This feature allows a base
station to be part of a channel group without requiring the Central Voter
(TBAS061) license.

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 PA sends an RF feedback
signal to the reciter for linearization and power control purposes. 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.

Reciter Control Board
Digital P25 signals from the receive RF interface pass through the digital
receiver and P25 modem to the control software in the control processor.
The control software passes the signal through the Ethernet interface to the
site controller (P25 trunked networks), to the console gateway
(conventional networks), or for a satellite, to the central voter in a simulcast
system.
Input to the Ethernet interface can be from the site controller (P25 trunked
networks), from the console gateway (conventional networks), or from the
central voter in a simulcast system. These inputs are processed by the
control processor and passed through the P25 modem to the transmitter. If
the base station is itself a central voter, this input can also be a received
signal, which is voted on and sent back through the Ethernet interface to the
site controller.
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

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.

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 1.2 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 1.2.
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 1.2.
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
28
Description
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.

Front Panel Fans
The front panel is equipped with three fans. One fan is for the PMU, and
the other two are for the reciter/PA pairs in a 50W base station, or for the
PA and reciter in a 100W base station, or for the receivers in a receive-only
base station (refer to “Appendix C – Identifying Front Panels” on
page 122). Front panel fans do not operate continuously, but are switched
on and off as needed. The PMU and PA control their own fan. Reciters
request the front panel to turn on their 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
any of the fans fail.
The fans turn on for the duration of time the base station takes to boot
from power up. The fans also turn on for a few seconds after the front
panel is refitted to a base station that is powered up.
Configuring Fan
Control
The operation of the PA fan is configurable via the web interface; you can
specify the threshold temperature at which the fan will be turned on, and
set the fan to operate only when the PA is transmitting.
Notice If a fan is not operational, the fan alarm will only be raised
when the fan is turned on, not at system start-up. To avoid discovering
a fan fault after leaving the site, Tait recommends running a diagnostics
fan test.
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.

General Safety and Regulatory
Information
This chapter provides general information on safety precautions for
operating the base station.
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 55lb
(25kg), or up to 62lb (28kg) 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 106). 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.

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 75 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/
ESD S20.20-1999 or BS EN 100015-4 1994.

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.

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 116 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 71 for more details).
Lightning Ground
4.1.3
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.
Equipment Ventilation
Always ensure there is adequate ventilation around the base station (refer
to “Cabinet and Rack Ventilation” on page 50).
Notice Do not operate it in a sealed cabinet. You must keep the
ambient temperature within the specified range, and we strongly recommended 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).
4.1.4
Ambient Temperature Sensor
The ambient temperature reading for the base station is provided by the
temperature sensor located on the front panel circuit board.

Cabinet and Rack Ventilation
The cooling airflow for the subrack enters through the front panel and exits
at the rear. For optimum thermal performance, the heated air that passes
through a base station must never 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 4.1 on
page 51.
Equipment installation should observe the following guidelines:

Installation
The recommended maximum number of subracks in a 38U cabinet is
five as shown in Figure 4.1 on page 51.
Any space at the front of the cabinet not occupied by equipment should
be covered by a blanking panel. Refer to Figure 4.1 on page 51.
Subrack placement in the cabinet should include a 2U gap at the top of
the cabinet.
To allow enough cooling airflow through a cabinet-mounted base
station, the cabinet should allow for 50 cu.ft/min for each subrack
(0.024 cu.m/s).
To ensure adequate ventilation, the cabinet should have a vent at the top
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.
The maximum ambient temperature at the base station front panels must
not exceed +140°F (+60°C).

59
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
4.4.6
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.
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 1.40 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, they 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.
Tait networks are deployed with default weak passwords. For security,
Tait strongly recommends changing the default password where applicable.

4.4.7
Tuning the Reciter and Receiver
In this section “reciter” also applies to the receiver module (receiveonly 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 B3-band reciter covers the 148 to 174MHz frequency
band. This is split into two sub-bands: 148 to 159MHz and
159 to 174MHz.
Each sub-band has its own helical filter (shown in Figure 4.3 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.

To check the RSSI level and tune the receiver front end (if required), follow
these steps:
1.
Remove the reciter from the subrack and reconnect the system
control bus cable to power up the module.
Tait can provide extender cables (TBC Reciter Power Cables) to enable
tuning with a subrack or from a bench power supply. To order these, the
part number is T01-01150-0001.
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 85.
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.
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 4.3) 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, turn the slug clockwise; for
a higher frequency, turn the slug anti-clockwise.
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.
Tait can provide extender cables (TBC Reciter Power Cables) to enable
tuning with a subrack or from a bench power supply. To order these, the
part number is T01-01150-0001.
The receiver in the H-band reciter covers one of the following frequency
sub-bands, depending on the model:
■
H1 - 400 to 440MHz
■
H2 - 440 to 480MHz
Each sub-band uses the same helical filter (shown in Figure 4.4 below).
The bandwidth of the helical filter is approximately ±5MHz.
The HH-band variant has no helical filter, so does not require tuning.

outer resonators (in any order). Each resonator should require
approximately the same amount of adjustment when tuning.
If tuning to a lower frequency, adjust the slug in (clockwise); for a
higher frequency, adjust the slug out (counterclockwise).
7.
Change the RF input signal and the reciter’s receive frequency to
2MHz 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.

Installing the Base Station on Site
4.5.1
General Installation Advice
When installing base stations, 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.
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.
Base stations may require an external frequency reference, a 1PPS signal,
and an NTP source, depending on the frequency band and type of radio
system.
The following general rules apply:
■
■
■
Base stations operating at or above 700MHz require an external
frequency reference to meet the frequency accuracy requirements for
transmitters and receivers.
Simulcast transmitters require an external frequency reference and a
1PPS signal so that transmissions can be timed with the required
accuracy. They also require an NTP source. Both the 1PPS and NTP
signals must be derived from a source that is GPS-disciplined. This will
ensure a common timestamp in logs across all units in the system.
P25 Phase 2 base stations require an external frequency reference and a
1PPS signal for site alignment of transmitters and receivers. They also
require an NTP source to ensure correct, long-term Phase 2 alignment.
The requirements for P25 Phase 1 systems are described in more detail
below. Also see “Connecting an External Frequency Reference” on
page 76 and “Connecting a 1PPS Source” on page 77.

An NTP source is also strongly recommended for P25 Phase 1
non-simulcast systems. This will ensure log timestamps are synchronized, which will assist the diagnosis of faults.
Synchronization requirements are more stringent with the introduction
of simulcast and with TDMA in Phase 2. See Technical Note TN-2411a
Providing Synchronization to Tait Networks.

PMU and on the ends of the cables do not have to support the full weight
of the cables.
Figure 4.8 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.

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.

4.6.3
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 module 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 3%
voltage drop at maximum load over the required length of lead.

4.6.4
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 problem for your system, we recommend connecting auxiliary power supply
boards in parallel to ensure an uninterrupted power supply for the ancillary equipment.
Auxiliary DC Power
Output Cabling
Network elements are supplied with a connector, as shown in Figure 4.10.
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.

4.6.5
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 transmissions.
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 4.9 on page 71).
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
for Installing the PA
We recommend the following installation procedures, which should protect
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 possible 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.

Connecting an External Frequency Reference
For K4 band, the internal frequency reference accuracy is inadequate, and
an external reference must be used. An external reference is also required
for simulcast and P25 Phase 2. The external reference frequency can be
10MHz or 12.8MHz, with an input level of 300mVpp to 5V pp. The reciter
automatically detects the frequency of the external reference and
configures itself accordingly. The stability of this reference should be as
shown below. For more details, see Technical Note TN-2411b Providing
Synchronization to Tait Networks.

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.

Connecting a 1PPS Source
Ω ΩA 1PPS signal is required for simulcast and P25 Phase 2 base stations.
Use a 50Ω coaxial cable (RG58 or RG223) to connect the source to the
base station’s 1PPS input. You can daisy-chain up to eight base stations
using F-junctions. We recommend that the cable length between the first
and last load is kept to a minimum. This will reduce any propagation
variation between base stations. The maximum overall cable length is 30m.
Terminate the last connection (including single base stations) with a 50Ω
resistor, otherwise reflections of the 1PPS pulse may occur.
Notice If 1PPS is used then 1PPS and NTP must both be derived
from the same time base. Normally this will be a GPS disciplined
source.

Ethernet Connection
The RJ-45 socket on the reciter’s rear panel provides the 10-BASE-T or
100-BASE-T Ethernet connection to the other devices in the network. Use
a Cat-5 cable to connect this socket to the Tait Network via a router or
switch.
The Web UI allows you to set the Ethernet port speed auto-negotiation to
10/100 Mbit/s or to negotiate a maximum 10 Mbit/s. Tait recommends that
you keep the port speed at the factory default setting of 10 Mbit/s. The
reciter hardware and software are scaled to meet the performance
requirements of processing multiple voice streams along with supervisory
control and management communications. 10 Mbit/s is ample for those
requirements. The 10/100 Mbit/s setting is provided for compatibility
reasons, but it is possible under high traffic conditions at 100 Mbit/s for
traffic arriving at the reciter at the full rate within a small timing window
to overflow internal buffers and therefore suffer packet loss. If you set the
port speed to 100 Mbit/s and observe QoS lost packet alarms, then review
your Ethernet port speed settings.
With the port speed at 10 Mbit/s it is particularly important to set the voice
QoS on the reciter port of your site router or switch to a strict priority queue
policy - which is the same policy that you should also be setting for your
site link ports. The default QoS settings restrict the voice bandwidth to 1/
25th of the port speed which is smaller than the required bandwidth for
typical systems at 10 Mbit/s.
If necessary, refer to “Ethernet Connector” on page 117 for a list of
Ethernet connection pin allocations.

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).
Notice If the base station is online when changing the IP address, it
is possible that the base station will restart. Tait recommends that all
configuration changes are made after taking the base station offline.
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.
Use the scroll keys to scroll through the available numbers for each
position in a line.
a. Set the IP address and press OK. This moves the cursor to the
next line. To move the cursor back to the previous line, press the
return key.
b. Set the Mask address and press OK.
c. Set the Gateway address and press OK.
d. The display shows “Setting Reciter 1 (or 2) address Please
wait...” while the base station confirms that the addresses are correct. When this process has finished, the display will show
“SUCCEEDED” or “FAILED” as appropriate. Press OK to return to
the previous menu.

5.2.3
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.

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 85.
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.
5.2.6
3.
The link to the base station is down. Use ping to check.
4.
A connection error may occur if your PC is using the organisation’s
web proxy, but the base station doesn’t have a valid gateway address
allowing it to send responses back to that proxy. Users should ensure
that all network parameters are correct (IP address, network mask
and gateway address). 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.
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 TB9400 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.

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.

Viewing Configuration Settings
The base station has many configuration settings that personalize it for its
particular role in the network. Some settings, such as those for alarm
thresholds (Configure > Alarms > Thresholds), always apply.
Others are channel-based so that they can be dynamically changed. To view
these, you first need to know the channel on which the base station is
operating. To see the channel number and profiles the base station is using,
select Monitor > Interfaces > Analog RF > (or P25 RF).

Viewing the Base Station and Network Identity
Each base station in a network has a unique base station and network
identity.
Select Identity > Identity and then Base Station or Network to view details
such as name, receiver number, default channel and network addresses.
Note that the Host name field has a maximum of 63 characters, and may
use the characters a–z, 0–9, dot and hyphen. You cannot use spaces.
The Link speed configuration option enables the Ethernet port speed autonegotiation to 10/100 MBits/s or to negotiate a maximum of 10 Mbits/s.
Under high traffic conditions it is possible for traffic arriving at the reciter
at the full rate (100 Mbits/s) within a small timing window to overflow
internal buffers and therefore suffer packet loss. To minimize this cause of
packet loss a setting of 10 Mbits/s is recommended.
Enter here the four lines of information you want to appear on the home
screen on the front panel display.

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.
The following parameters are not restored on a base station when a
configuration is restored:
■
Keypad enabled
■
Trunking capability
■
Trunking node priority
■
Host name
■
Default channel
■
Operating mode
■
Front panel test lines 1 through 4
■
IP address
■
Subnet mask
■
Gateway address
■
Link speed
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 configuration 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.

5.4.5
Configuring Single Base Stations
It is possible to operate the base station as a single base station (for
example, trunked, non simulcast, or as a conventional single repeater). The
following explains the special considerations when configuring single base
stations.
Channel Group
Membership
Although single base stations are not actually part of a channel group, their
channel configurations (Configure > Base Station > Channels) must still
select a channel group (Configure > Channel Group > Channel Groups).
Once a channel group has been selected, the following parameters need to
be configured.
Channel Group IP
Address
The selected channel group must be configured for single base station
operation. Specify 127.0.0.1 as the channel group IP address. This is the
base station’s localhost address and stops it from attempting to send voice
packets to other base stations.
Single base station operation should not require marshaling. Channel
group and simulcast operation have no meaning for a single transceiver.
Interactions within the software, however, mean that control channel
operation and transmit tail operation both depend on the configured
value. It is recommended to leave the marshaling duration at the value
of 40ms for single base station operation.
Marshaling
Duration
Trunking Interface
5.4.6
Single base stations need a control connection to their site controller.
A single base station interfaces to the site controller in the same way as the
master base station in a trunked channel group. Select Configure >
Network Interfaces > Trunking to configure this.
Configuring Receive-Only Base Stations
You can program a receiver with the same configuration as a reciter. This
will keep the number of required configuration files to a minimum and, if
possible, re-use existing configuration files.
Transmit information for the receiver will be displayed in the web
interface, but this can be ignored. Also, some polled SNMP parameters,
such as Tx NAC, will return the correct transmitter configuration data, but
none of these parameters is used by the receiver.
5.4.7
Configuring Base Stations in a Channel Group
You can configure the way the base station behaves in its channel group.
Also, qualified network engineers can change DSCP assignments so that
routers and switches provide a different quality of service to different types
of IP packets. In trunked networks, many base stations are single and not
98
Working with Base Stations from Your PC
TB9400 Installation and Operation Manual

actually part of a channel group. However, they still must be assigned to a
channel group configuration and some of its parameters must be set
correctly.
To disable channel group operation, open the channel group profile you
want to disable and deselect that profile in the channel group table.
5.4.8
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. See below for the severity of each alarm.
Major
An alarm of this severity causes the node to take a base station out of
service. This alarm must be cleared at the base station before the channel
will be used again. To avoid this, an alarm’s severity must be set to ‘Minor’
or ‘Notification’.
Minor
An alarm of this severity means the base station has a fault that will need
addressing, but it remains capable of operating as part of the radio network.
Notification
An alarm of this severity is not reported to the Node.

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.
5.4.10
Preparing to Download Firmware
New versions of base station firmware are remotely downloaded to base
stations from a package server (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 can be downloaded as a zip file from
the Tait support website.
If you click ‘Cancel’ while downloading a firmware package, it takes
approximately 20 seconds for the cancellation to take effect and for the
base station to respond.
This procedure describes using the Mongoose web server.
Installing the
Firmware Package
The installation procedure copies files into a folder and adds items to the
Windows Start menu (Start > Programs > Tait Applications > TB9400).
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 background until stopped, or the computer is shut down. Mongoose must
also run from the same folder as the firmware files.
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 package server computer.
2.
Extract the zip file, then navigate to the root folder and double-click
TB9400.msi to run the Windows installer.
1. Mongoose runs on Windows only.
100

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.
Setting Up a Central
Package Server
It is beyond the scope of this manual to describe the exact procedure for
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 packages. Downloading another package will replace the inactive package.
Setting up a
Temporary Package
Server
If you want to use a laptop as a temporary package server, you can
temporarily override the package server IP address and port in each base
station.
1.
Run Mongoose on the package server (Start > Programs >
Tait Applications > TB9400 > 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

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
Checks
Simulcast
We suggest you monitor the following operational parameters using the
web interface:
■
VSWR
■
DC input voltage, especially on transmit
■
any temperature alarms
■
forward power
■
external reference absent
■
NTP unsynchronised
■
1PPS
■
Simulcast Unsynchronized
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.

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). Both the PMU and PA modules have built-in protection
mechanisms to prevent damage from overheating.

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.

Appendix C – Identifying Front Panels
You must fit the correct type of front panel to your base station. Each type
of base station has a different combination of modules, and must use a front
panel fitted with fan ducts that match those modules. Each module, or pair
of modules, requires a specific type of fan duct to ensure the cooling air
flow passes directly through the modules’ heatsinks. The illustration below
shows the different front panels and identifies each fan duct by its part
number (the xx in the part number indicates the version of the part).

Glossary
This glossary contains an alphabetical list of terms and abbreviations, from
within this manual, related to the Tait network and the TB9400 base station.
base station
A radio receiver and transmitter that is located in a specific place (at a site)
that enables a two-way radio to communicate with a dispatcher or over a
larger range with other two-way radios. Specifically, Tait TB9400
equipment in a subrack.

of a channel group operate on the same RF frequencies, are linked by an IP
network and share a common multicast IP address.
channel profile
A named group of configuration settings that help to define the properties
of a channel. Each channel in the channel table must have a channel profile
assigned to it.
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.
configuration file
Consists of all the configuration settings needed for a base station, stored
as a file.
conventional
network

ultimate end user sub license) an enforceable
sublicense agreement that prohibits any other
transfer and that contains restrictions substantially identical to the terms set forth in this Software License Agreement. Except as stated in the
foregoing, Licensee and any transferee(s) authorised by this Section may not otherwise transfer
or make available any Tait Software to any third
party nor permit any party to do so. Licensee
will, on request, make available evidence reasonably satisfactory to Tait demonstrating compliance with all the foregoing.
Section 8 TERM AND TERMINATION
8.1. Licensee’s right to use the Software and
Documentation will commence when the Designated Products are supplied by Tait to Licensee
and will continue for the life of the Designated
Products with which or for which the Software
and Documentation are supplied, unless
Licensee breaches this Agreement, in which case
this Agreement and Licensee's right to use the
Software and Documentation may be terminated
immediately upon notice by Tait.
8.2. Within thirty (30) days after termination of
this Agreement, Licensee must certify in writing
to Tait that all copies of the Software have been
removed or deleted from the Designated Products and that all copies of the Software and Documentation have been returned to Tait or
destroyed by Licensee and are no longer in use
by Licensee.
8.3. Licensee acknowledges that Tait made a
considerable investment of resources in the
development, marketing, and distribution of the
Software and Documentation and that Licensee's
breach of this Agreement will result in irreparable harm to Tait for which monetary damages
would be inadequate. If Licensee breaches this
Agreement, Tait may terminate this Agreement
and be entitled to all available remedies at law or
in equity including immediate injunctive relief
and repossession of all non-embedded Software
and associated Documentation. Licensee shall
pay all Tait costs (on an indemnity basis) for the
enforcement of the terms of this Agreement.
Section 9 CONFIDENTIALITY
Licensee acknowledges that the Software and
Documentation contain proprietary and Confidential Information valuable to Tait and are Tait
trade secrets, and Licensee agrees to respect the
confidentiality of the information contained in
the Software and Documentation.
Section 10 LIMITATION OF LIABILITY
10.1. In no circumstances shall Tait be under any
liability to Licensee, or any other person whatsoever, whether in Tort (including negligence),
Contract (except as expressly provided in this
Agreement), Equity, under any Statute, or otherwise at law for any losses or damages whether
general, special, exemplary, punitive, direct,
131
indirect, or consequential arising out of or in connection with any use or inability of using the
Software.
10.2. Licensee’s sole remedy against Tait will be
limited to breach of contract and Tait sole and
total liability for any such claim shall be limited
at the option of Tait to the repair or replacement
of the Software or the refund of the purchase
price of the Software.
Section 11 GENERAL
11.1. COPYRIGHT NOTICES. The existence of
a copyright notice on the Software will not be
construed as an admission or presumption of
publication of the Software or public disclosure
of any trade secrets associated with the Software.
11.2. COMPLIANCE WITH LAWS. Licensee
acknowledges that the Software may be subject
to the laws and regulations of the jurisdiction
covering the supply of the Designated Products
and will comply with all applicable laws and regulations, including export laws and regulations,
of that country.
11.3. ASSIGNMENTS AND SUBCONTRACTING. Tait may assign its rights or subcontract its
obligations under this Agreement, or encumber
or sell its rights in any Software, without prior
notice to, or consent of, Licensee.
11.4. GOVERNING LAW. This Agreement shall
be subject to and construed in accordance with
New Zealand law and disputes between the parties concerning the provisions hereof shall be
determined by the New Zealand Courts of Law.
Provided however Tait may at its election bring
proceedings for breach of the terms hereof or for
the enforcement of any judgment in relation to a
breach of the terms hereof in any jurisdiction Tait
considers fit for the purpose of ensuring compliance with the terms hereof or obtaining relief for
breach of the terms hereof.
11.5. THIRD-PARTY BENEFICIARIES. This
Agreement is entered into solely for the benefit
of Tait and Licensee. No third party has the right
to make any claim or assert any right under this
Agreement, and no third party is deemed a beneficiary of this Agreement. Notwithstanding the
foregoing, any licensor or supplier of third-party
software included in the Software will be a direct
and intended third-party beneficiary of this
Agreement.
11.6. SURVIVAL. Sections 4, 5, 6.3, 7, 8, 9, 10,
and 11 survive the termination of this Agreement.
11.7. ORDER OF PRECEDENCE. In the event
of inconsistencies between this Agreement and
any other Agreement between the parties, the
parties agree that, with respect to the specific
subject matter of this Agreement, this Agreement
prevails.
11.8. SECURITY. Tait uses reasonable means in
the design and writing of its own Software and
the acquisition of third-party Software in order to
limit Security Vulnerabilities. While no software
can be guaranteed to be free from Security Vulnerabilities, if a Security Vulnerability is discovered, Tait will take the steps specified in Section
6 of this Agreement.
11.9. EXPORT. Licensee will not transfer,
132
directly or indirectly, any Designated Product,
Documentation or Software furnished hereunder
or the direct product of such Documentation or
Software to any country for which New Zealand
or any other applicable country requires an
export license or other governmental approval
without first obtaining such license or approval.
11.10. SEVERABILITY. In the event that any
part or parts of this Agreement shall be held illegal or null and void by any court or administrative body of competent jurisdiction, such determination shall not affect the remaining terms
which shall remain in full force and effect as if
such part or parts held to be illegal or void had
not been included in this Agreement. Tait may
replace the invalid or unenforceable provision
with a valid and enforceable provision that
achieves the original intent and economic effect
of this Agreement.
11.11. CONSUMER GUARANTEES. Licensee
acknowledges that the licenses supplied in terms
of this agreement are supplied to Licensee in
business, and that the guarantees and other provisions of prevailing consumer protection legislation shall not apply.
11.12. WHOLE AGREEMENT. Licensee
acknowledges that it has read this Agreement,
understands it and agrees to be bound by its terms
and conditions. Licensee also agrees that, subject
only to the express terms of any other agreement
between Tait and Licensee to the contrary, this is
the complete and exclusive statement of the
Agreement between it and Tait in relation to the
Software. This Agreement supersedes any proposal or prior agreement, oral or written, and any
other communications between Licensee and
Tait relating to the Software and the Designated
Products.
