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 base station operates Project 25 trunked or trunked simulcast radio
network. 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 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 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.

1.2
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) 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.

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 40
for more information.
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 subaudible signaling.
The base station can also operate as part of an analog conventional
simulcast network. It is fully IP-connected and requires no training. It also
features an integral voter (thus requiring no external voter), and CTCSS
subaudible signaling.
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.
Analog Air Interface
(TBAS041 - Default
Licence)
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 a trunking system. 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.
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.
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.
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
© Tait Limited June 2016
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)
P25 Phase 1 and analog. 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 RISC 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 RISC
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
station out of service. However, the front panel is still operational and can
be used in the normal way.

Power Management and Distribution
The PMU manages the supply of power to ensure uninterrupted operation
of the base station. A range of parameters is monitored and these can
trigger alarms that are sent to the reciter. Alarms can be monitored via the
web interface and reported via SNMP traps; they are also recorded in the
reciter’s internal log file.
AC to DC
Changeover
When the PMU has an AC and a DC module, the base station can be
powered by either the AC (mains) or the DC (battery) supply. The base
station will default to the AC supply if both supplies are provided. If the
AC supply becomes unavailable, a seamless changeover from the AC to
DC supply takes place, providing that the battery voltage is above the
configured minimum startup voltage. You can use a web browser to check
whether the base station is running on battery or mains power.
DC Operation
When the base station is running off the DC supply and the battery voltage
falls below the configured minimum, the base station will enter battery
protection mode to protect the battery and base station equipment. The
standby power supply card maintains the power to the PMU
microprocessor, while the rest of the PMU is shut down. When the battery
voltage rises to the configured startup setting, power is resumed to the DC
supply. Refer to “PMU Operation on DC Input” on page 28 for more
detailed information.
Auxiliary Power
Control
The output from the auxiliary power supply board can be used to power
other site equipment. The maximum output is 40W.
Distribution
Figure 1.8 shows how power is distributed to modules in the subrack. The
28VDC output from the PMU is fed directly to the PA in a single base
station, or directly to PA 1 in a dual base station, and to the other modules
via the subrack interconnect board. Power to the reciters and front panel is
current-limited by self-resetting fuses on the subrack board.
The AC converter has a series switch which breaks the phase input to the
converter. The DC input, however, has much higher current ratings. Its
switch does not disconnect power from the DC converter itself, but disables
the converter by switching off its control circuitry.
The outputs from both the AC and DC high power converters are added
together and fed to the modules via the high-current outputs. The auxiliary
output is also tapped off this summed output.

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 123). 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
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
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.
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.

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.

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.

4.1
Before You Begin
4.1.1
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.
4.1.2
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 117 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 72 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 51).
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.

4.1.5
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 reenter 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 52.
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 4.1 on page 52.
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
Fans
The base station does not require auxiliary extractor fans mounted in the
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.

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:
4.4.1
■
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).
Confirming Operation
Notice Make sure that the RF output is connected to a suitable attenuator or dummy load. Do not remove the load while the PA is transmitting 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.

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 82 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:
3.
■
Channel configurations
■
Alarm control and SNMP agent
■
Network interfaces
■
channel groups and quality of service
■
channel and signaling profiles
■
CWID
■
miscellaneous items such as minimum battery voltages, fan
control, NTP and package servers.
Make the changes needed in each form and click ‘Save.’ All changes
made in the form will be applied when, and only when, the form is
saved.
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.
4.4.3
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).

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 and channel
groups).
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.
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.
60
Installation
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.

4.4.6
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.
Figure 4.3
Identifying the B-band receiver front end helical filters
B3: 159 to 174MHz
B3: 148 to 159MHz
To check the RSSI level and tune the receiver front end (if required), follow
these steps:
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.

1.
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 86.
2.
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.
3.
Set the reciter to the new receive frequency.
4.
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.
5.
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, adjust the slug in (clockwise); for a higher frequency, adjust the slug out (counterclockwise).
6.
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.
7.
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.

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 77 and “Connecting a 1PPS Source” on page 78.

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.
4.5.2
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.
