1 Description

The Tait TB9300 base station is a robust state-of-the-art digital fixed

station that combines Tait’s proven strengths in reliability, high

performance and modular design with software-based configurability and

operation, digital signal processing, and voice-over-IP technology.

The base station operates as a transceiver in trunked DMR or MPT

networks, and as a repeater in DMR or analog conventional networks. In a

DMR or MPT trunked network, the TB9300 provides control channel and

traffic channel functions, including stand-alone operation in fallback mode.

The TB9300 operates as a simple, conventional analog repeater with

CTCSS1 or DCS subaudible signaling2.

The base station combines industry-leading digital voice quality with

rugged design specifications and intuitive user interfaces. These products

have been designed to meet the demanding needs of professional radio

users.

The ability of the base station to link stations using standard Internet

Protocol communications, and to add features through software options

ensures that systems designed with the TB9300 are scalable in both size

and functionality.

Its Ethernet interface provides built-in network connectivity. This network

supports voice-over-IP in DMR networks, and remote management of all

base stations via a web browser.

1. Private Line (PL).

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

later release.

TB9300 Installation and Operation Manual Description 11

1.1 Features

The following are some of the features of the base station:

■Fully compliant with the DMR Tier 2 and Tier 3 Standards.

Can therefore interoperate with any similarly compliant radios.

■Analog conventional repeater operation.

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

IP network including standalone operation.

■Can be completely managed remotely from a PC running a web

browser: configuration, alarm monitoring, fault diagnosis, feature and

firmware upgrades. Alarms can also be reported via SNMP traps,

allowing integration with an SNMP-based network management

system.

■An integrated wiring solution is provided for the system control bus and

DC power connections to each module in the subrack.

■Reciters (receiver/exciter modules) can be replaced without affecting

the operation of other reciters in the same subrack.

■Rugged construction with generous heatsinks and fan-forced cooling

for continuous operation from –22°F to +140°F (–30°C to +60°C).

12 Description TB9300 Installation and Operation Manual

1.2 Modules

The base station consists of a subrack with up to two physical transmit/

receive channels.

The single PMU (power management unit) supplies and manages power to

the whole subrack (refer to “Theory of Operation” on page 21). One reciter

and one PA (power amplifier) are needed for each physical transmit/receive

channel. There is also a front panel with user controls and fans. The

modules are interconnected at the front of the subrack. External

connections to the modules are located at the rear.

Modules come in different variants depending, for example, on the RF

band or the supply voltage.

Each module is inserted into the 4U subrack from the front and is secured

at the front with a metal clamp. Both clamp and module are easily removed

for rapid module replacement. The modules are secured laterally with

plastic guides that clip into the top and bottom of the subrack. These guides

can be easily repositioned to change the configuration of a subrack. The

heavier modules are also secured laterally by metal tabs at the rear of the

subrack.

The following provides a brief description of the available modules.

Subrack The 4U subrack is made of passivated steel and is designed to fit into a

standard 19 inch rack or cabinet. The subrack is fitted with an interconnect

board that connects the system control bus and power to the modules and

front panel. The position of a module in the subrack is defined by the socket

on the subrack interconnect board to which the module is connected by the

system control bus.

TB9300 Installation and Operation Manual Description 13

Front Panel The front panel is mounted onto the subrack with two quick-release

fasteners. It incorporates the indicator LEDs, four-line LCD display, user

controls, ambient temperature sensor and cooling fans.

The indicator LEDS allow some monitoring of the operational status of the

base station. The user controls and display allow the technician to

configure the IP address of each module. Refer to “Front Panel” on page 39

for more information.

The microphone input and speaker are not used in this release of the

TB9300.

Reciter The reciter module comprises the

receiver, exciter and digital control

circuitry. The reciter provides the

Ethernet interface and system inputs

and outputs.

14 Description TB9300 Installation and Operation Manual

Power Amplifier The PA amplifies the RF output from the reciter and is available in 50W

and 100W models.

The 50W model mounts vertically in the subrack, while the 100W model

mounts horizontally as it has a wider heatsink. The 100W PA is also fitted

with an airflow duct.

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

PMU.

Power Management

Unit

The PMU provides the 28VDC

power supply for the modules in the

subrack. It can operate on

120/230VAC 50/60Hz nominal, and

12, 24 or 48VDC nominal. The input

voltage can be AC, DC, or both AC

and DC, depending on the model. The

PMU also has an auxiliary DC output

of 13.65VDC, 27.3VDC, or

54.6VDC, depending on the model.

1.3 Mechanical Assembly

This section illustrates the main mechanical components of the base

station.

Figure 1.1 below shows the configuration for a typical dual 50W base

station. The subrack has six slots, numbered from right to left as viewed

from the front of the subrack. The PMU occupies slots 5 and 6, with the

reciters in slots 1 and 2. The two PAs are mounted vertically in slots 3 and

4 with the heatsinks facing each other. The airflow separator between the

PAs helps to direct the cooling airflow evenly through each heatsink. The

PMU and each pair of reciters and PAs have their own cooling fans.

The front panel can be easily removed from the subrack by undoing two

quick-release fasteners. Refer to “Replacing Modules” on page 99 for more

details.

1.4 Frequency Bands and Sub-bands

Much of the circuitry in the base station is common to all frequency bands,

and is therefore covered by a single description in this manual. In some

cases the descriptions refer to specific bands or sub-bands, and these are

identified with the letters listed in the following table.

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

a base station with retransmission of receive frequencies.

1.5 Applications

The TB9300 is designed for operation in a Tait TN9300 DMR Tier 2

conventional radio network, a Tait TN9300 DMR Tier 3 trunked radio

network, an MPT-IP network, or as an analog conventional repeater.

In a DMR Tier 2 conventional network it can operate as a stand-alone

repeater, or as a member of a multi-site system (under the supervision of a

DMR conventional node). Since DMR provides two logical channels

(timeslots) simultaneously for each radio frequency (physical channel),

two users can alternately access the same frequency, one in each timeslot.

Base stations on different sites can be linked together to form channel

groups. A base station can support two channel groups, one in each

timeslot.

In a DMR Tier 3 trunked network it can operate as a traffic channel or a

control channel. With two logical channels for each radio frequency, a

single TB9300 base station can provide two traffic channels, two control

channels, or both a traffic channel and a control channel. In an MPT

network, the TB9300 operates as a control channel or as a traffic channel.

The TB9300 operates with a trunking node or in fallback operation, both of

which can be either trunked or conventional.

In analog operation it can operate as a conventional repeater with CTCSS1

or DCS subaudible signaling2.

For more information, refer to the DMR System Manual.

1. Private Line (PL).

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

later release.

20 Description TB9300 Installation and Operation Manual

1.6 Licenses

Some operational functions of the base station are controlled by licenses.

These functions will not work unless you purchase the appropriate feature

license and enable the feature set controlled by that license. The feature sets

currently available are listed below.

The central voter and satellite licences are alternatives. The base station

is fully functional without them.

The base stations in a Tait DMR Tier 3 Network are controlled by a node

(DMR trunking controller). Tait sells three types of node: Full, Express and

Access. Each type of node has different capabilities. Refer to TN-2134 for

more information.

Analog Air Interface

(TBAS301 - Default

Licence)

A base station with this license can operate as an MPT transceiver or an

analog conventional repeater.

DMR Trunking Full

(TBAS300)

A base station with this license can accept connections from any node/

standalone node1. In single-site trunking and fallback modes, this license

entitles a standalone node to control a single site of up to 20 physical

channels.

DMR Trunking

Express

(TBAS302)

A base station with this license can accept connections from any Express

node/standalone node or Access standalone node. In single-site trunking

and fallback modes, this license entitles a standalone node to control a

single site of up to 20 physical channels. For more information on DMR

Trunking Express, see the TB9300 System Manual

DMR Trunking

Access

(TBAS303)

A base station with this license can accept connections only from an Access

standalone node. This license entitles a standalone node to control a single

site of up to four physical channels.

DMR Conventional

(TBAS304)

A base station with this license can operate in a Tait DMR Tier 2

conventional network. It can operate as a standalone repeater, or as a

member of a multi-site system (under the supervision of a DMR

conventional node).

A base station with both a DMR Conventional license and a valid DMR

trunking license (such as Full, Express or Access) can be configured to

operate in either mode. This enables a DMR Tier 2 base station to be

reconfigured and re-used in a DMR Tier 3 trunked network.

1. The base station itself can act as a DMR trunking controller, but with lim-

ited functionality. The base station is then said to be a standalone node.

TB9300 Installation and Operation Manual Description 21

1.7 Theory of Operation

The reciter receives RF signals from its RF input and sends RF from its RF

output to the PA, along with a PA key signal. The reciter also receives

signals from, and sends signals to, the system interface, the Ethernet

interface, and the front panel (see Figure 1.4).

A system control bus interconnects the modules and carries alarm and

control signaling between the reciter and the other modules (refer to

“Intermodule Communications” on page 24 for more details).

The Ethernet interface carries voice over IP and also allows maintainer

access via a web browser.

The reciter carries out signal processing and has overall control of the base

station. Its circuit boards are shown in Figure 1.5.

The receiver board contains all the receiver circuitry, while the exciter

circuitry is located on the transmit forward board.

The reciter control board converts information between analog and digital

and controls the maintainer’s access via the front panel. It performs the air

interface signal processing for digital DMR operation, gives the base

station an identity as a network element, and provides the physical

connections for the Ethernet and system interfaces.

1.7.1 Signal Paths

Figure 1.6 gives an overview of signal paths within the reciter.

Digital DMR signals from the receive RF interface pass through the digital

receiver and DMR modem to the control software in the RISC processor.

The control software passes the signal through the Ethernet interface to the

node controller.

Input to the Ethernet interface is from the node controller. This input is

processed by the RISC and passed through the DMR modem to the

transmitter.

Analog FM signals from the receive RF interface pass through the digital

receiver and are converted to G.711 before being modulated and

retransmitted.

1.7.2 Online and Offline Modes

The base station normally operates in Online mode, but you can put it into

Offline mode via its web interface.

Online Mode In Online mode, the base station performs its normal functions.

Offline Mode Some procedures, such as activating firmware or running certain diagnostic

tests, require the base station to be in Offline mode. This takes the base

station out of service. However, the front panel is still operational and can

be used in the normal way.

1.7.4 Power Management and Distribution

The PMU manages the supply of power to ensure uninterrupted operation

of the base station. A range of parameters is monitored and these can

trigger alarms that are sent to the reciter. Alarms can be monitored via the

web interface and reported via SNMP traps; they are also recorded in the

reciter’s internal log file.

AC to DC

Changeover

When the PMU has an AC and a DC module, the base station can be

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 27 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.

1.7.5 PMU Operation on DC Input

The operation of the PMU on DC input is controlled by three sets of

parameters:

■user-programmable alarms

■user-programmable startup and shutdown limits

■battery protection limits

The voltage range for each of these parameters is provided in Table 1.1 on

page 28. Figure 1.9 on page 29 illustrates how these parameters interact,

and how they control the operation of the PMU over a range of DC input

voltages.

Alarms User-programmable alarms can be set for low or high battery voltage

(Configure > Alarms > Thresholds). The alarms will be triggered when the

set voltage levels are reached. These limits are subject to the tolerances of

the battery protection circuitry, as stated in “Battery Protection (Fail-safe)

Limits” in Table 1.1.

Startup and

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 1.1.

Notice It is possible to set the startup voltage of the base station

below the nominal voltage of the battery. Continuing to use a battery for

extended periods when it is below its nominal voltage will severely

shorten its service life. For more information on battery management,

we recommend that you consult the battery manufacturer.

Battery Protection

Limits

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.

1.7.6 Front Panel Fans

The front panel is equipped with three fans. Fan 1 is for the reciters, fan 2

is for the PAs, and fan 3 is for the PMU. Front panel fans do not operate

continuously, but are switched on and off as needed by their associated

module. In a dual base station either PA or reciter can turn on its fan. The

reciter in slot 1can also carry out a fan test on all three fans.

Front panel fans are 3-wire fans (power, ground, and rotation detect). The

reciter can monitor whether the fans are rotating and generate an alarm if

the fan fails.

The fans turn on for a few seconds when the base station is powered up, and

also after the front panel is refitted to a base station which is powered up.

Configuring Fan

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.

TB9300 Installation and Operation Manual General Safety and Regulatory Information 31

2 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 62lb

(28kg), or up to 66lb (30kg) complete with packaging. We recommend

that you have another person help you unpack and move the equipment.

The TBAA03-16 carrying handles will make it easier to move the

equipment once it has been unpacked. If necessary, remove the modules

from the subrack before moving it (refer to “Replacing Modules” on

page 99). 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.

48 Installation TB9300 Installation and Operation Manual

4 Installation

This chapter provides information on the site requirements for your

TB9300 equipment and also describes how to install the base station in a

standard 19 inch rack or cabinet.

If this is your first time installing a TB9300 base station, we recommend

that you read the entire chapter before beginning the actual installation.

TB9300 Installation and Operation Manual Installation 49

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 110 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 70 for more details).

Lightning Ground It is extremely important for the security of the site and its equipment that

you take adequate precautions against lightning strike. Because it is outside

the scope of this manual to provide comprehensive information on this

subject, we recommend that you conform to your country’s standards

organization or regulatory body.

4.1.3 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 rec-

ommended that you ensure that the cooling airflow is not restricted.

Notice The cooling fans are mounted on the front panel and will only

operate when the panel is fitted correctly to the front of the subrack. To

ensure adequate airflow through the base station, do not operate it for

more than a few minutes with the front panel removed (e.g. for servicing

purposes).

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.

50 Installation TB9300 Installation and Operation Manual

4.1.5 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:

■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).

4.2 Unpacking and Moving the Subrack

The subrack is packed in a strong corrugated cardboard carton with top and

bottom foam cushions. To prevent personal injury and damage to the

equipment, we recommend that two people unpack and move the subrack.

To remove the subrack from the carton, follow the procedure illustrated in

Figure 4.2.

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

(28kg), or up to 66lb (30kg) complete with packaging. We recommend

that you have another person help you unpack and move the equipment.

The TBAA03-16 carrying handles will make it easier to move the

equipment once it has been unpacked. If necessary, remove the modules

from the subrack before moving it (refer to “Replacing Modules” on

page 99). In all cases follow safe lifting practices.

1. Cut the tape securing the flaps at the top of the carton and fold them

flat against the sides b.

2. Rotate the carton carefully onto its side c and then onto its top d,

ensuring that none of the flaps is trapped underneath.

Remove the cushion from the bottom of the subrack f.

4. Rotate the subrack and cushion carefully over the rear of the subrack

g so that it is the right way up with the cushion on top h. Remove

the cushion from the top of the subrack i.

Disposal of

Packaging

If you do not need to keep the packaging, we recommend that you recycle

it according to your local recycling methods. The foam cushions are CFC-

and HCFC-free and may be burnt in a suitable waste-to-energy combustion

facility, or compacted in landfill.

Notice Before making changes, you should save the configuration to

your PC or network. This provides a baseline which can be restored to

the base station if the configuration information becomes lost or cor-

rupted.

You should also back up the configuration before downgrading to a dif-

ferent software release. Note that if you downgrade and then upgrade

software, configuration values for new features may become default.

4.4.4 Recommended Configuration Settings

In a dual base station only base station 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).

4.4.5 Restricted Port Numbers

Certain configuration settings in the base station’s web interface require

you to enter a port number (for example, the trunking interface).

Two ranges of port numbers are unavailable for use with the base station.

The web interface will prevent you from entering a number from these

ranges, as explained below.

4.4.6 Changing the Root Password

Notice The following procedure can be carried out only if secure

shell access (SSH) is enabled. Secure shell access to the base station is

disabled by default from version 1.35 onwards. To enable SSH, select

Tools > Settings > Secure shell and click Start.

The root password to the Linux operating system of the reciter is a possible

security risk. The equipment is delivered with a default password that is

well known. Knowledge of the password could be used to render the

equipment inoperable, for example by deleting files. If you are concerned

about the security risk that this poses, change the password. If Tait provides

support services, 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.

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.

4.4.7 Tuning the Reciter

B-Band

C-Band

Before the base station is installed on site, you may need to tune the

receiver front end. The receiver front end requires tuning if the receive

frequency is shifted more than 2MHz away from the previously set

frequency, or the RSSI level of the new frequency is more than 1dB lower

than the RSSI level of the previously set frequency.

The receiver in the B-band reciter covers one of the following frequency

bands, depending on the model:

■B2 - 136 to 156 MHz

■B3 - 148 to 174 MHz

■C3 - 216 to 225 MHZ

B-Band frequencies are split into 2 sub-bands:

■B2 - 136 to 146MHz and 146 to 156 MHz

■B3 - 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.

filters

B2: 146 to 156MHz

B3: 159 to 174MHz

B3: 148 to 159 MHz

C3: 216 to 215 MHz

62 Installation TB9300 Installation and Operation Manual

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

these steps:

1. Remove the reciterfrom the subrack and reconnect the system

control bus cable to power up the module.

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 83.

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

of –80dBm into the reciter’s RF input. Check that the RSSI reading

on the RF Interface page is –80dBm ±1dB. Note this reading.

4. Set the reciter to the new receive frequency.

5. Change the RF input signal to the new receive frequency at

–80dBm. Check that the RSSI reading is –80dBm ±1dB. If it is, the

receiver front end does not require tuning. If it is not, go to the next

step.

6. Using the Johanson tuning tool1, adjust the correct helical filter for

the new frequency (as shown in Figure 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 (clock-

wise); for a higher frequency, adjust the slug out (counterclockwise).

7. Change the RF input signal and the reciter’s receive frequency to

0.5MHz above and below the required frequency and check that the

RSSI reading does not drop by more than 0.5dB from the reading at

the required frequency.

8. Recalibrate the RSSI at the new frequency (Calibrate > Reciter >

RSSI).

If you wish to confirm the accuracy of the tuning procedure, carry out a

sensitivity measurement at the new frequency.

H-Band Before the base station is installed on site, you may need to tune the

receiver front end. The receiver front end requires tuning if the receive

frequency is shifted more than 5MHz away from the previously set

frequency, or the RSSI level of the new frequency is more than 1dB lower

than the RSSI level of the previously set frequency.

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 and HC - 400 to 440MHz

■H2 - 440 to 480MHz

■H3 - 470 to 520MHz.

Each sub-band uses the same helical filter (shown in Figure 4.4 below).

The bandwidth of the helical filter is approximately ±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 reciter.

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 83.

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

–80dBm into the reciter’s RF input. Check that the RSSI reading on the RF

Interface page is –80dBm ±1dB. Note this reading.

4. Set the reciter to the new receive frequency.

5. Change the RF input signal to the new receive frequency at

–80dBm. Check that the RSSI reading is –80dBm ±1dB. If it is, the

receiver front end does not require tuning. If it is not, go to the next

step.

6. Using the Johanson tuning tool1, adjust the helical filter for the new

frequency (as shown in Figure 4.4) 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.

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.

8. Re-calibrate 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.

4.5 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. Isolators should be used

at all transmitter outputs.

When the outputs of more than one transmitter are combined, their voltages

add, and the resulting peak envelope power is not simply the sum of their

powers, but is equal to the power of one of them multiplied by the square

of the number of sources. Cables, components, and hardware must be rated

to withstand the peak envelope power.

During the commissioning process, all transmitters should be activated

together using a diagnostic test tone, while the receiver RSSI is monitored.

There should be no perceptible increase in RSSI while the transmitters are

active.

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.

4.5.3 Mounting the Subrack

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

(28kg), or up to 66lb (30kg) complete with packaging. We recommend

that you have another person help you unpack and move the equipment.

The TBAA03-16 carrying handles will make it easier to move the

equipment once it has been unpacked. If necessary, remove the modules

from the subrack before moving it (refer to “Replacing Modules” on

page 99). In all cases follow safe lifting practices.

1. Remove the front panel, as described in “Preliminary Disassembly”

on page 101.

2. Fit the subrack into the cabinet or rack and secure it firmly with an

M6 (0.25in) screw, flat and spring washer in each of the four main

mounting holes b, as shown in Figure 4.5.

If you need extra mounting security, additional mounting holes c are

provided at the rear of the subrack for auxiliary support brackets.

Auxiliary Support

Bracket

TBAA03-13 auxiliary support brackets can be fitted to the rear of the

subrack to provide additional mounting security. Figure 4.7 shows a

standard TBAA03-13 bracket b fitted in a typical Tait cabinet c. If you

are not using the Tait cabinet, you may have to make your own brackets to

suit your installation.

Notice You must fit the auxiliary support brackets if you intend to

transport a cabinet fitted with a fully built-up base station.

We also recommend that you fit the brackets under the following

conditions:

■when the installation is in an area prone to earthquakes

■when third party equipment is installed hard up underneath the base

station subrack.

General Cabling We recommend that you try to route all cables to and from the base station

along the side of the cabinet so the cooling airflow is not restricted.

TB9300 Installation and Operation Manual Installation 69

DC Power Cabling DC power cables should be well supported so that the terminals on the

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

of the cables.

Figure 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.
