10 Description TB9400 Installation and Operation Manual

1 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.

TB9400 Installation and Operation Manual Description 11

1.1 Features

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

■Fully compliant with the Project 25 Common Air Interface.

Can therefore interoperate with any similarly compliant radios.

■P25 Phase 1 operation (C4FM and CQPSK modulation).

■P25 Phase 2 operation (H-DQPSK modulation).

■Analog conventional repeater operation.

■Analog conventional simulcast operation on an IP backbone requiring

no audio calibration or training.

■Linear power amplifier allows operation with Linear Simulcast

Modulation (LSM).

■Integrated built-in voting facility. No external voter is needed.

■P25 simulcast conventional repeater / line connected base station.

■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 TB9400 Installation and Operation Manual

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.

1. Refer to “Frequency Bands and Sub-bands” on page 18.

TB9400 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 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.

reciter receiver

14 Description TB9400 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. 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.

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

reciter and PA pairs to the right of it in slots 1 to 4. Each PA is mounted

vertically with its heatsink facing its associated reciter. The PMU and each

reciter/PA pair 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 106 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 band, the TB9400 is considered to be configured as a base

station with retransmission of receive frequencies.

Frequency

B band B3 = 148MHz to 174MHz ✓✓ ✓

H band H1 = 400MHz to 440MHz

H2 = 440MHz to 480MHz ✓✓

K band K4 = 762MHz to 870MHza✓✓ ✓

a. The actual frequency coverage in this band is:

Transmit: 762MHz to 776MHz, and 850MHz to 870MHz

Receive: 792MHz to 824MHz

TB9400 Installation and Operation Manual Description 19

1.5 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.

20 Description TB9400 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.

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.

TB9400 Installation and Operation Manual Description 21

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.

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 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.

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 P25 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 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.

1.7.3 Intermodule Communications

A system control bus and a subrack interconnect board link the modules in

the subrack and carry alarm and control signaling between the reciter and

the other modules, as shown in Figure 1.7.

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 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.

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 1.2 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.

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. 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.

Information

This chapter provides general information on safety precautions for

operating the base station.

TB9400 Installation and Operation Manual General Safety and Regulatory Information 33

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.

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.

TB9400 Installation and Operation Manual Installation 49

4Installation

This chapter provides information on the site requirements for your

TB9400 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 TB9400 base station, we recommend

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

50 Installation TB9400 Installation and Operation Manual

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 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 51).

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.

TB9400 Installation and Operation Manual Installation 51

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 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 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.

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 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.

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.

Figure 4.2 Unpacking the subrack

54 Installation TB9400 Installation and Operation Manual

3. Slide the carton upwards over the foam cushions and lift it away e.

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.

4.4 Initial Setting Up

Before putting the base station into service, you may want to carry out

some basic functional testing, configuration, and tuning (if required). This

section provides an overview of these procedures:

■checking that the base station powers up correctly

■checking the basic functionality of the base station by using the tests

available in the web interface

■customizing the configuration for the intended installation and

verifying that the configuration is correct

■changing the root password

■tuning the base station (if required).

4.4.1 Confirming Operation

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

uator or dummy load. Do not remove the load while the PA is transmit-

ting as this may damage the PA output stage.

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

2. Check that the base station powers up correctly:

■The front panel display will show “Please wait...” while the base

station starts up (this may take up to two minutes). When the

startup process is complete, the display will show the home

screen.

■The cooling fans in the front panel will run at full speed for a few

seconds, then run at low speed while the base station starts up,

and then assume standard operation. One or more fans may

operate, depending on the temperature of the modules.

4.4.2 Customizing the Configuration

The following steps provide an overview of the process used to configure

the base station with the settings it needs. Refer to the Help for detailed

information.

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

Station” on page 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:

■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.

3. 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).

60 Installation TB9400 Installation and Operation Manual

4.4.4 Restricted Port Numbers

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

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

4.4.5 Changing the Root Password

Notice The following procedure can be carried out only if secure

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

disabled by default from version 1.40 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.

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.

4.4.6 Tuning the Reciter and Receiver

In this section “reciter” also applies to the receiver module (receive-

only 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:

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.

B3: 159 to 174MHz

62 Installation TB9400 Installation and Operation Manual

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 (clock-

wise); 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.

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 86.

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.

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. 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.

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.

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.

TB9400 Installation and Operation Manual Installation 67

P25 Phase 1 The requirements for an external frequency reference and a 1PPS signal are

set out in the following table.

An NTP source is also strongly recommended for P25 Phase 1

non-simulcast systems. This will ensure log timestamps are synchro-

nized, 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.

4.5.3 Mounting the Subrack

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.

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

on page 108.

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.

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.
