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 is designed for operation in a Project 25 trunked or trunked

simulcast radio network. The ability of the base station to link stations

using standard Internet Protocol communications, and to add features

through software options ensures that P25 systems designed with the

TB9400 are scalable in both size and functionality.

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.

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.

10 Description TB9400 Installation and Operation Manual

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.

■Linear power amplifier allows operation with Linear Simulcast

Modulation (LSM). Future software upgrades will also allow

P25 Phase 2 operation (H-DQPSK modulation).

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

■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 –30°C to +60°C (–22°F to +140°F).

TB9400 Installation and Operation Manual Description 11

1.2 Modules

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

channels, or up to two receive-only channels.

Receive-only base stations are currently available for operation only on

B3 band (148MHz to 174MHz1).

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

the whole subrack (refer to “Theory of Operation” on page 19). 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.

Reciter The reciter module comprises the

receiver, exciter and digital control

circuitry. The reciter provides the

Ethernet interface and system inputs

and outputs.

Receive-only reciters are not fitted

with the transmit circuitry and are

physically unable to transmit.

1. Refer to “Frequency Bands and Sub-bands” on page 17.

12 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.

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 36

for more information.

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

TB9400.

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.

1.3 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 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.

1.5 Applications

The TB9400 is designed for operation in a Tait P25 trunked radio network.

It can operate as a single base station or as part of a simulcast channel

group, and as a traffic channel or control channel.

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. We

also recommend using an NTP server at each site, as this will ensure a

common timestamp in logs across all units in the system.

The base station can be provided as a receive-only variant in systems that

need sites to enhance the receive coverage. The reciter in a receive-only

base station is physically unable to transmit.

For more information, refer to the appropriate Tait P25 System Manual.

Frequency Identification Frequency Band and Sub-band

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

18 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.

P25 Common Air

Interface

Allows the base station to go into Online mode. Base stations are always

provided with this license.

P25 Trunking

Operation

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.

Networking with

Centralized Voter

This feature is required in any base station that is used in a voted

configuration, such as simulcast. It also allows a base station to act as a

central voter.

Simulcast

Transmitter

This feature is required in base stations that have transmitters and belong

to a simulcast network.

Linear Simulcast

Modulation

Allows the base station to transmit using the LSM modulation scheme.

This scheme allows increased site separation in simulcast networks.

Failsoft for P25

Trunking

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

Operation

(not yet available)

This feature will allow the base station to operate in trunking mode using

two-slot TDMA as defined by the P25 Phase 2 standard.

TB9400 Installation and Operation Manual Description 19

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.

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 mode, 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, or to the central voter in a simulcast system.

Input to the Ethernet interface can be from the site controller, 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.

Specific configuration settings for dual base stations are described in

“Recommended Configuration Settings” on page 75.

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 25 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 26. Figure 1.9 on page 27 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. 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. 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.

30 General Safety and Regulatory Information TB9400 Installation and Operation Manual

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 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.

2.2 Equipment Safety

2.2.1 Installation and Servicing Personnel

The equipment should be installed and serviced only by qualified

personnel.

2.2.2 Preventing Damage to the PA

The base station has been designed to operate safely under a wide range of

antenna loading conditions. Transmitting into a low VSWR will maximize

the power delivered to the antenna.

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

Load transients (switching or removing the load) can damage the PA output

stage. See “Connecting RF” on page 90 for recommendations.

2.2.3 ESD Precautions

Notice This equipment contains devices which are susceptible to

damage from static charges. You must handle these devices carefully

and according to the procedures described in the manufacturers’ data

books.

We recommend you purchase an antistatic bench kit from a reputable

manufacturer and install and test it according to the manufacturer’s

instructions. Figure 2.1 shows a typical antistatic bench set-up.

You can obtain further information on antistatic precautions and the

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

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

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 Working with Base Stations from Your PC 49

4.2.3 Responding to Security Warnings

When your browser connects to a TB9400 for the first time, it raises a

security warning. Normally, secure websites have a security certificate

issued by a trusted Certification Authority. This is to foil attempts by rogue

websites to pretend to be something they are not. The TB9400 creates a

self-signed certificate when the reciter’s firmware is installed. Your

browser raises a security warning because the security certificate was not

issued by a trusted Certification Authority. The browser has a way of letting

you override or bypass the security warning, as explained below.

You can be confident that you are not connecting to a rogue website

pretending to be your TB9400, so follow the procedure below to tell the

browser that the security certificate is OK. The browser then stores the

security certificate and will not raise a warning on subsequent connections,

unless the IP address of the TB9400 changes. For more information, refer

to http://support.microsoft.com/kb/931850 (Internet Explorer) or search

for “security certificate” in your browser’s Help.

Firefox 1. When the message “This Connection is Untrusted” appears, click

I Understand the Risks.

2. Click Add Exception.

3. The Location field includes details specific to your TB9400. Without

changing the default values, click Confirm Security Exception.

Internet Explorer 8 1. Click Continue to this website (not recommended).

2. Click Certificate Error.

3. Click View certificates. The Certificate dialog box, General tab is

displayed.

4. Click Install Certificate and then follow the Certificate Import

Wizard to install the certificate. Proceed to the end without changing

the default values. When the Security Warning window appears,

click Yes.

Internet Explorer 9 Click Continue to this website (not recommended). Internet Explorer 9

does not provide a means of installing the certificate, however you can log

into the base station as normal.

If you log out of the base station and then log back in, Internet Explorer

may display a warning that it has blocked the website from displaying

content. Click Show content to continue to the login screen.

recommend that you download it and store it on your computer as an off-

site backup. The base station identity and network identity are not saved as

part of the configuration file.

You may want to develop a master configuration and upload it to all base

stations in the network. The master configuration can contain all the

different channel configurations and can be common to all base stations.

The base station identity selects the default channel.

Base stations are delivered with a default configuration which provides

a safe set of values. We recommend that you download it and store it on

your computer as a backup before changing and saving any configura-

tion settings.

4.4.5 Configuring Single Base Stations

Most base stations in non-simulcast trunked networks are single. They

interface to a site controller but not to other base stations. The following

explains the special considerations when configuring single base stations.

Channel Group

Membership

Although single base stations are not actually part of a channel group, their

channel configurations (Configure > Base Station > Channels) must still

select a channel group (Configure > Channel Group > Channel Groups).

Channel Group IP

Address

The selected channel group must be configured for single base station

operation. Specify 127.0.0.1 as the channel group IP address. This stops the

base station from attempting to send voice packets to other base stations.

Preamble Although the single base station’s transmitter does not receive voice

packets from other channel group members, it still receives them from

other base stations via trunking controllers. So, while most channel group

settings have no effect, the preamble setting still applies and determines

how large the transmit buffer is.

The default setting of 40ms is intended for internal jitter only. If the base

station is a traffic channel, you may have to increase the preamble. Voice

arriving at the base station’s trunking interface has travelled from another

base station via the trunking site controller and could have significantly

more jitter.

Marshalling

Duration

Although marshalling duration applies only to control channels, and has no

effect on traffic channels, we recommend that you configure the

marshalling duration for each base station as described below. This will

allow any base station to operate as a control channel when required.

60 Working with Base Stations from Your PC TB9400 Installation and Operation Manual

Configure the channel group settings to specify fixed marshalling and

allow a duration of 40ms. This gives the control channel’s transmitter an

appropriate buffer (control channels do not use the preamble to regulate the

transmit buffer).

Trunking Interface Single base stations need a control connection to their site controller. A

single base station interfaces to the site controller in the same way as the

master base station in a trunked channel group. Select Configure >

Network Interfaces > Trunking to configure this.

4.4.6 Configuring Base Stations in a Channel Group

You can configure the way the base station behaves in its channel group.

Also, qualified network engineers can change DSCP assignments, so that

routers and switches provide a different quality of service to different types

of IP packets.

In trunked networks, many base stations are single and not actually part of

a channel group. However, they still must be assigned to a channel group

configuration and some of its parameters must be set correctly.

4.4.7 Setting Up Custom Alarms

Each of the base station’s 12 digital inputs can be used to raise a custom

alarm when the input goes high or low. The Custom Alarms form

(Configure > Alarms > Custom Alarms) allows you to assign a name to

each custom alarm, and to configure whether the alarm is triggered when

the digital input goes high or low. Custom alarms are reported via the web

interface and SNMP traps.

Custom alarms are used to provide an alarm when an external event

activates a digital input. You can rename any of the available alarms to

provide a more meaningful name, such as “Door open”.

4.4.8 Disabling the Front Panel Keypad

You can disable the front panel keypad to prevent access to the base station

via the front panel menus. Select Configure > Base Station > Miscellaneous

and in the Front Panel area clear the Keypad enabled check box.

Notice If you disable the front panel keypad, you cannot use it to find

out the base station’s IP address. Make sure that you store the IP address

securely and do not lose it.

4.4.9 Preparing to Download Firmware

New versions of base station firmware are remotely downloaded to base

stations from a package server (a web server application). You can set up a

single computer to be the central package server for all the base stations on

your network, using a web server of your choice. Tait also provides the

Mongoose1 web server as part of the base station firmware package for use

with a temporary package server, such as a laptop.

The base station firmware package is provided on the product CD, and can

also be downloaded as a zip file from the Tait support website.

This procedure describes using the Mongoose web server.

Installing the

Firmware Package

The installation procedure copies files into a folder and adds items to the

Windows Start menu (Start > Programs > Tait Applications > TB9400).

From the Start menu you can then access the Help, licenses, manuals and

release notes for each firmware package, and also start Mongoose.

You do not have to install Mongoose to make it work, because it is a

self-contained executable file. Once started, it will run in the back-

ground until stopped, or the computer is shut down. Mongoose must

also run from the same folder as the firmware files.

If you have a product CD:

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

computer.

2. If the CD does not autorun, navigate to the CD’s root folder and

double-click TB9400.msi to run the Windows installer.

If you are downloading a base station package zip file:

1. Save the zip file to a suitable location on the hard drive of the pack-

age server computer.

2. Extract the zip file, then navigate to the root folder and double-click

TB9400.msi to run the Windows installer.

Notice Tait recommends that the maximum length of the path to the

location of the extracted files is 100 characters. Using a longer path may

cause the files to be extracted incorrectly.

1. Mongoose runs on Windows only.

62 Working with Base Stations from Your PC TB9400 Installation and Operation Manual

Setting Up a Central

Package Server

It is beyond the scope of this manual to describe the exact procedure for

setting up a central package server for any particular network. Tait expects

that each customer will configure their own package server according to the

requirements for their network.

However, you do need to configure each base station with the IP address

and port of the package server computer.

1. Log in to the base station and select Configure > Base Station >

Miscellaneous.

2. Under Package server, enter the IP address and port number of the

package server.

3. Download the firmware as described in the Help.

Notice The base station has enough space for two firmware pack-

ages. If the base station already has two packages, delete the unwanted

package before downloading another.

Setting up a

Temporary Package

Server

If you want to use a laptop as a temporary package server, you can

temporarily override the package server IP address and port in each base

station.

1. Run Mongoose on the package server (Start > Programs > Tait

Applications > TB9400 > Mongoose).

2. Windows Firewall may raise a Security Alert about allowing

Mongoose to access your network or the internet.

a. In Windows 7 allow access to private networks.

b. In Windows XP click Unblock.

3. Log in to the base station and select Tools > Firmware > Download.

4. Under Package server, enter the IP address of the laptop. The default

port number is 8080.

5. Download the firmware as described in the Help.

6. If you have trouble with any of the above procedures, please

consider the following points:

■The firmware download process uses the HTTP protocol. If you

are using a laptop from outside the radio communications

network, make sure that HTTP traffic can get through the

firewall.

■If Mongoose fails to start, it may already be running, or another

application may be using port 8080.

■If the error message “Could not find index file” appears when

listing packages, Windows security may be silently blocking

access for Mongoose. Turn off the laptop’s WiFi and temporarily

disable its firewall, then try again.

5Installation

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.

66 Installation TB9400 Installation and Operation Manual

5.1 Before You Begin

5.1.1 Equipment Security

The security of your base station equipment is a high priority. If the site is

not fully secure, the base station should at least be locked in a secure

cabinet to prevent unauthorized access.

5.1.2 Grounding and Lightning Protection

Electrical Ground The base station modules are grounded by physical contact between the

module case and the subrack. To ensure a good ground connection you

must tighten each module retaining clamp securely (refer to “Final

Reassembly” on page 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 86 for more details).

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

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

the scope of this manual to provide comprehensive information on this

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

organization or regulatory body.

5.1.3 Equipment Ventilation

Always ensure there is adequate ventilation around the base station.

Notice Do not operate it in a sealed cabinet. You must keep the

ambient temperature within the specified range, and we strongly rec-

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

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

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

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

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

purposes).

5.1.4 Ambient Temperature Sensor

The ambient temperature reading for the base station is provided by the

temperature sensor located on the front panel circuit board.

TB9400 Installation and Operation Manual Installation 67

5.1.5 Cabinet and Rack Ventilation

The cooling airflow for the base station enters through the front panel and

exits at the rear of the subrack. For optimum thermal performance, the

heated air that has passed through a base station must not be allowed to re-

enter the air intakes on the front panel. Any space at the front of the cabinet

not occupied by equipment should be covered by a blanking panel. Refer

to Figure 5.1 on page 68.

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

we recommend the following:

■an area of at least 23in2 (150cm2) of unrestricted ventilation slots or

holes in front of the air intakes for the fans for each subrack; for

example, thirty 0.25x3.3in (6x85mm) slots will allow the

recommended airflow

■a vent in the top of the cabinet with an area of approximately 23in2

(150cm2) per subrack, or a similar area of ventilation per subrack at the

rear of the cabinet behind each subrack

■a 2U gap at the top of the cabinet.

Notice The ventilation opening must be unrestricted. If the slots or

holes are covered with a filter, mesh or grille, the open area must be

increased to allow the same airflow as an unrestricted opening.

The maximum ambient temperature entering the cabinet must not exceed

+140°F (+60°C).

If you are installing multiple subracks in a cabinet, ensure that there will be

enough cooling airflow through the cabinet after the equipment has been

installed. For example, the recommended maximum number of subracks in

a 38U cabinet is five, as shown in Figure 5.1 on page 68.

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.

5.2 Unpacking and Moving the Subrack

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

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

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

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

Figure 5.2.

Caution A subrack complete with modules can weigh up to 46lb

(21kg), or up to 53lb (24kg) 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.

Figure 5.2 Unpacking the subrack

70 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.

5.4 Initial Setting Up

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

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

section provides an overview of these procedures:

■checking that the base station powers up correctly

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

available in the web interface

■customizing the configuration for the intended installation and

verifying that the configuration is correct

■changing the root password

■tuning the base station (if required).

5.4.1 Confirming Operation

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

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

ting as this may damage the PA output stage.

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

2. Check that the base station powers up correctly:

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

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

startup process is complete, the display will show the home

screen.

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

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

and then assume standard operation. One or more fans may

operate, depending on the temperature of the modules.

5.4.2 Customizing the Configuration

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

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

information.

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

Station” on page 46 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.

We recommend that you save the configuration to your PC or network.

First make a backup copy of the configuration (which is stored in the base

station as a file), then save this file to a folder on your PC or network. This

provides a backup which can be restored to the base station if the

configuration information becomes lost or corrupted.

5.4.3 Recommended Configuration Settings

In a dual base station only reciter 1 communicates directly with the PMU

and front panel. Therefore the following configuration settings are

recommended for dual base station operation:

■Disable the “PMU not detected” alarm on base station 2 (Configure >

Alarms > Control > PMU).

■Disable the “FP not detected” alarm on base station 2 (Configure >

Alarms > Control > Front panel).

76 Installation TB9400 Installation and Operation Manual

5.4.4 Restricted Port Numbers

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

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

5.4.5 Changing the Root Password

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

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

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

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

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

support services, it may need to know the password.

Notice If you change the password and then lose it, the equipment

must be returned to Tait. Make sure that you store the password securely

and do not lose it.

To change the root password, follow these steps.

1. Log in from your PC to the base station using SSH client software

such as PuTTY. The username is “root” and the default password is

“k1w1”.

2. At the # prompt, enter the command “passwd”.

3. Follow the on-screen instructions.

4. Record the password in a secure location.

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.

TB9400 Installation and Operation Manual Installation 77

5.4.6 Tuning the Reciter

B3-Band Reciter 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 5.3 below) which is electronically switched in or out of circuit

depending on the frequency programmed into the reciter. The bandwidth of

these helical filters is approximately ±1.5MHz.

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 50.

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.

Figure 5.3 Identifying the B3-band receiver front end helical filters

148 to 159MHz

159 to 174MHz

78 Installation TB9400 Installation and Operation Manual

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

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

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

step.

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

the new frequency (as shown in Figure 5.3) to obtain a peak RSSI

reading. This reading should be within 1dB of the reading at the

previous frequency.

Adjust the center resonator of the filter first, followed by the two

outer resonators (in any order). Each resonator should require

approximately the same amount of adjustment when tuning.

A change in frequency of 5MHz requires approximately one turn of the

tuning slug. If tuning to a lower frequency, adjust the slug in (clock-

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

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

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

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

the required frequency.

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

RSSI).

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

sensitivity measurement at the new frequency.

ber 937-00013-00.

TB9400 Installation and Operation Manual Installation 79

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

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

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

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

than the RSSI level of the previously set frequency.

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

sub-bands, depending on the model:

■H1 - 400 to 440MHz

■H2 - 440 to 480MHz.

Both sub-bands use the same helical filter (shown in Figure 5.4 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 50.

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 5.4) 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.

K-Band Reciter The K-band reciter does not require tuning.

5.5 Installing the Base Station on Site

5.5.1 Base Stations for Trunked Systems

When installing base stations that are part of a trunked system, it is very

important to observe good site engineering rules. This is especially true

when the channels are combined into a single antenna.

If at all possible, the RF planner should avoid frequency plans in which the

Rx to Tx spacing is an exact multiple of the trunked channel spacing, thus

forcing Tx intermodulation products to fall outside the Rx channels.

Cables and antennas should be of high quality construction. Solid shield

heliax type cables are best, but if braided shield cables must be used for

short distances, their braids must be silver-plated.

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

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

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

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

to withstand the peak envelope power.

During the commissioning process, all transmitters should be activated

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

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

active.

5.5.2 Equipment Required

It is beyond the scope of this manual to list every piece of equipment that

an installation technician should carry. However, the following tools are

specifically required for installing the base station:

5.5.3 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 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 5.5.

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 5.7 shows a

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

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

suit your installation.

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

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

We also recommend that you fit the brackets under the following

conditions:

■when the installation is in an area prone to earthquakes

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

station subrack.

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

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

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

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

of the cables.

Figure 5.8 shows two recommended methods of securing these cables to

prevent straining either set of terminals.

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

protect against accidental shorts.

5.6.2 Connecting AC Power

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

65Hz. A standard 3-wire grounded socket outlet must be used to supply the

AC power. The socket outlet must be installed near the equipment and must

be easily accessible. This outlet should be connected to an AC power

supply capable of providing at least 600W. The requirements of two typical

AC supplies are given in the following table.

Your base station should come supplied

with a power supply cord to connect the

male IEC connector on the PMU to the

local AC supply. The pins of the IEC

connector on the PMU are identified at

right.

5.6.3 Connecting DC Power

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

input (depending on the model) with negative or positive ground. There is

a minimum DC startup threshold to prevent damaging a battery which has

little capacity left.

You must connect the DC supply from the battery to the PMU via a fuse or

DC-rated circuit breaker with a contact separation of 3mm, and with the

appropriate rating, as shown in the table below. The DC input leads should

be of a suitable gauge to ensure less than 0.2V drop at maximum load over

the required length of lead.

Terminate and insulate the DC input leads to protect them from

accidentally shorting to the subrack if the PMU is removed before the leads

are disconnected. Protective covers for the DC terminals are supplied with

each PMU.

We recommend a screw torque of 18–20lbf·in (2–2.25N·m).

5.6.4 Connecting the Auxiliary DC Power Output

The PMU can provide an auxiliary DC output from the auxiliary power

supply board. This board is available with an output of 13.65VDC,

27.3VDC, or 54.6VDC (depending on the model), and is current limited to

3A, 1.5A or 750mA respectively. This power supply is permanently on as

soon as the base station has finished powering up, and is available on the

auxiliary output connector on the rear panel.

You can connect multiple auxiliary power supply boards in parallel for

redundancy purposes, or to provide an output greater than 40W. Although

no active current sharing is used, auxiliary boards connected in parallel will

current-share before reaching their power limit. The failure (or switching

off) of one auxiliary board will not load any other paralleled auxiliary

boards in the circuit.

The auxiliary power supply turns off briefly when the PMU restarts

after a firmware upgrade. This interruption may also cause any ancillary

equipment powered from the auxiliary supply to restart. If this is a prob-

lem for your system, we recommend connecting auxiliary power supply

boards in parallel to ensure an uninterrupted power supply for the ancil-

lary equipment.

Auxiliary DC Power

Output Cabling

Network elements are supplied with a connector, as shown in Figure 5.11.

You can use this to connect the PMU’s auxiliary DC power output to

another device (refer to “PMU Auxiliary DC Output” on page 111 for the

pin allocations).

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

available.

5.6.5 Connecting RF

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

as this may damage the PA output stage. Before disconnecting any RF

cables, put the base station into Offline mode to prevent any transmis-

sions.

The RF input to the base station is via the marked BNC connector on the

rear panel of the reciter. The RF output is via the N-type connector on the

rear panel of the PA (refer to Figure 5.9 on page 86).

Cables and antennas should be of high quality construction. Solid shield

heliax type cables are best, but if braided shield cables must be used for

short distances, their braids must be silver-plated.

Recommendations

for Installing the PA

We recommend the following installation procedures, which should protect

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

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

duplexer between the PA and the load. Fit the isolator as close as pos-

sible to the RF output connector on the PA. Do not connect any

switching equipment between the isolator and the PA, unless the

switch cannot operate while there is RF present (i.e. the base station

is transmitting).

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

building.

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

defects.

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

PA.

Explanation The circuit design of the PA protects the circuitry from high VSWR. This

makes it difficult to damage the RF power device by keying the PA into a

mismatched load, or if the load deteriorates over even a short period of time

(milliseconds).

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

happen at the same time:

■there is a step change in the PA load (for example, the load is removed)

■the PA is transmitting

■the feed line loss between the PA and the mismatch is <1dB.

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

destroyed, and some may fail after repeated load interruptions.

TB9400 Installation and Operation Manual Installation 91

5.6.6 Connecting an External Frequency Reference

For K4 Band, the internal frequency reference accuracy is inadequate, and

an external reference must be used. An external reference is also required

for simulcast. The external reference frequency can be 10MHz or

12.8MHz, with an input level of 300mVpp to 5Vpp. The stability of this

reference should be better than 50 parts per billion (for non-simulcast) or

≤1 part per billion (for simulcast). The reciter automatically detects the

frequency of the external reference and configures itself accordingly.

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

alarm (Configure > Alarms > Control).

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

reference to the base station’s external reference frequency input. You can

daisy-chain up to eight base stations using F-junctions. The maximum

overall cable length is 30m. Terminate the last connection with a 50Ω load.

92 Installation TB9400 Installation and Operation Manual

5.6.7 Connecting a 1PPS Source

A 1PPS signal is required for simulcast base stations. Use a 50Ω coaxial

cable (RG58 or RG223) to connect the source to the base station’s 1PPS

input. You can daisy-chain up to eight base stations using F-junctions. We

recommend that the cable length between the first and last load is kept to a

minimum. This will reduce any propagation variation between base

stations. The maximum overall cable length is 30m. Terminate the last

connection with a 50Ω resistor, otherwise reflections of the 1PPS pulse

may occur.

A 1PPS signal will be required for all base stations operating in a P25

Phase 2 system. If you intend to upgrade TB9400 base stations to P25

Phase 2 operation at a later date, we suggest that you provide the 1PPS

source, or at least the necessary cables, at the time of installation.

5.6.8 Ethernet Connection

The RJ-45 socket on the reciter’s rear panel provides the 10BASE-T or

100BASE-T Ethernet connection to the other devices in the network. Use

Cat-5 cable to connect this socket to the Tait P25 Network via a router or

switch.

If necessary, refer to “Ethernet Connector” on page 111 for a list of

Ethernet connection pin allocations.

6 Maintenance

The base station is designed to be very reliable and should require little

maintenance. However, performing regular checks will prolong the life of

the equipment and prevent problems from happening.

It is beyond the scope of this manual to list every check that you should

perform on your base station. The type and frequency of maintenance

checks will depend on the location and type of your system. The checks and

procedures listed below can be used as a starting point for your

maintenance schedule.

Performance

Checks

We suggest you monitor the following operational parameters using the

web interface:

■VSWR

■DC input voltage, especially on transmit

■any temperature alarms.

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

is operating.

Reciter We recommend that you calibrate the reciter after three months of

operation, and then annually for H-band reciters, or every three years for

B3-band reciters. The calibration procedure is described in the Help

(Calibrate > Reciter > Internal reference), and requires a calibrated

frequency generator.

PA There are no special maintenance requirements for the PA.

PMU There are no special maintenance requirements for the PMU. However, we

suggest that you periodically check that the screws on the DC input

terminals are tightened to the recommended torque of 18–20lbf·in

(2–2.25N·m). They may work loose with thermal cycling. Also, if you are

using battery back-up, you should check the batteries regularly in

accordance with the manufacturer’s recommendations.

Ventilation The base station has been designed to have a front-to-back cooling airflow.

We strongly recommend that you periodically check and maintain the

ventilation requirements described in “Equipment Ventilation” on page 66

to ensure a long life and trouble-free operation for your base station. Also

check for a build-up of dust in and around the module heatsink fins, front

panel air intakes, and fan ducts.

Appendix C – Identifying Front Panels

You must fit the correct type of front panel to your base station. Each type

of base station has a different combination of modules, and must use a front

panel fitted with fan ducts that match those modules. Each module, or pair

of modules, requires a specific type of fan duct to ensure the cooling air

flow passes directly through the modules’ heatsinks. The illustration below

shows the different front panels and identifies each fan duct by its part

number (the xx in the part number indicates the version of the part).

again until the level falls to the lower trigger point. An adequate hysteresis

prevents the receiver gate from repeatedly muting and unmuting when the

level varies around the trigger point.

I2CA bi-directional two-wire serial bus which is used to connect integrated

circuits (ICs). I2C is a multi-master bus, which means that multiple chips

can be connected to the same bus, and each one can act as a master by

initiating a data transfer. Used in the TB9400 for communications between

reciter 1 and the PMU.

network of computers. A NAT sits between the public Internet and the

network it serves, and works by rewriting IP addresses and port numbers in

IP headers on the fly so the packets all appear to be coming from (or going

to) the single public IP address of the NAT device instead of the actual

source or destination.

authorized by this Agreement; or (viii) use, or

permit the use of, the Software in a manner that

would result in the production of a copy of the

Software by any means whatsoever other than

what is permitted in this Agreement. Licensee

may make one copy of the Software to be used

solely for archival, back-up, or disaster recovery

purposes; provided that Licensee may not oper-

ate that copy of the Software at the same time as

the original Software is being operated. Licensee

may make as many copies of the Documentation

as it may reasonably require for the internal use

of the Software.

4.3. Unless otherwise authorized by Tait in writ-

ing, Licensee will not, and will not enable or

allow any third party to: (i) install a copy of the

Software on more than one unit of a Designated

Product; or (ii) copy or transfer Software

installed on one unit of a Designated Product to

any other device. Licensee may temporarily

transfer Software installed on a Designated Prod-

uct to another device if the Designated Product is

inoperable or malfunctioning. Temporary trans-

fer of the Software to another device must be dis-

continued when the original Designated Product

is returned to operation and the Software must be

removed from the other device.

4.4. Licensee will maintain, during the term of

this Agreement and for a period of two years

thereafter, accurate records relating to this

license grant to verify compliance with this

Agreement. Tait, or a third party nominated by

Tait, may inspect Licensee’s premises, books and

records, upon reasonable prior notice to

Licensee, during Licensee’s normal business

hours and subject to Licensee's facility and secu-

rity regulations. Tait is responsible for the pay-

ment of all expenses and costs of the inspection,

provided that Licensee shall indemnify Tait for

all costs (including audit costs and legal costs on

a solicitor client basis) if Licensee has breached

the terms of this Agreement. Any information

obtained by Tait during the course of the inspec-

tion will be kept in strict confidence by Tait and

used solely for the purpose of verifying

Licensee's compliance with the terms of this

Agreement.

Section 5 OWNERSHIP AND TITLE

Tait, its licensors, and its suppliers retain all of

their Intellectual Property Rights in and to the

Software and Documentation, in any form. No

rights are granted to Licensee under this Agree-

ment by implication, estoppel or otherwise,

except for those rights which are expressly

granted to Licensee in this Agreement. All Intel-

lectual Property developed, originated, or pre-

pared by Tait in connection with providing the

Software, Designated Products, Documentation,

or related services, remains vested exclusively in

Tait, and Licensee will not have any shared

development or other Intellectual Property

Rights.

Section 6 LIMITED WARRANTY;

DISCLAIMER OF WARRANTY

6.1. The commencement date and the term of the

Software warranty will be a period of one (1)

year from Tait shipment of the Software. If

Licensee is not in breach of any obligations under

this Agreement, Tait warrants that the unmodi-

fied Software, when used properly and in accor-

dance with the Documentation and this Agree-

ment, will be free from a reproducible defect that

eliminates the functionality or successful opera-

tion of a feature critical to the primary function-

ality or successful operation of the Software.

Whether a defect has occurred will be deter-

mined solely by Tait. Tait does not warrant that

Licensee’s use of the Software or the Designated

Products will be uninterrupted, error-free, com-

pletely free of Security Vulnerabilities, or that the

Software or the Designated Products will meet

Licensee’s particular requirements. Tait makes

TB9400 Installation and Operation Manual 133

no representations or warranties with respect to

any third-party software included in the Soft-

ware.

6.2 Tait sole obligation to Licensee, and

Licensee’s exclusive remedy under this warranty,

is to use reasonable efforts to remedy any mate-

rial Software defect covered by this warranty.

These efforts will involve either replacing the

media or attempting to correct significant,

demonstrable program or documentation errors

or Security Vulnerabilities. If Tait cannot correct

the defect within a reasonable time, then at Tait

option, Tait will replace the defective Software

with functionally equivalent Software, license to

Licensee substitute Software which will accom-

plish the same objective, or terminate the license

and refund Licensee’s paid license fee. If Tait

investigation of the perceived defect reveals that

no such defect in fact exists, Tait may recover its

costs in respect of such investigation from

Licensee.

6.3. Tait disclaims any and all other warranties

relating to the Software or Documentation other

than the express warranties set forth in this Sec-

tion 6. Warranties in Section 6 are in lieu of all

other warranties whether express or implied, oral

or written, and including without limitation any

and all implied warranties of condition, title,

non-infringement, merchantability, or fitness for

a particular purpose or use by Licensee (whether

Tait knows, has reason to know, has been advised

of, or is otherwise aware of any such purpose or

use), whether arising by law, by reason of custom

or usage of trade, or by course of dealing. In addi-

tion, Tait disclaims any warranty to any person

other than Licensee with respect to the Software

or Documentation.

Section 7 TRANSFERS

7.1. Licensee will not transfer the Software or

Documentation to any third party without spe-

cific prior written consent from Tait. Tait may

withhold such consent or at its own discretion

make the consent conditional upon the transferee

paying applicable license fees and agreeing to be

bound by this Agreement.

7.2. In the case of a value-added reseller or dis-

tributor of Tait Designated Products, the consent

referred to in Section 7.1 may be contained in a

Tait Reseller or Tait Distributor Agreement.

7.3. If the Designated Products are Tait vehicle-

mounted mobile products or hand-carried porta-

ble radio products and Licensee transfers owner-

ship of the Tait mobile or portable radio products

to a third party, Licensee may assign its right to

use the Software which is embedded in or fur-

nished for use with the radio products and the

related Documentation; provided that Licensee

transfers all copies of the Software and Docu-

mentation to the transferee.

7.4. For the avoidance of any doubt, Section 7.3

excludes TaitNet Infrastructure, or the products

listed at any time under network products at:

http://www.taitradio.com.

7.5. If Licensee, as a contractor or subcontractor

(integrator), is purchasing Tait Designated Prod-

ucts and licensing Software not for its own inter-

nal use but for end use only by a Customer, the

Licensee may transfer such Software, but only if

a) Licensee transfers all copies of such Software

and the related Documentation to the transferee

and b) Licensee has first obtained from its Cus-

tomer (and, if Licensee is acting as a subcontrac-

tor, from the interim transferee(s) and from the

ultimate end user sub license) an enforceable

sublicense agreement that prohibits any other

transfer and that contains restrictions substan-

tially identical to the terms set forth in this Soft-

ware License Agreement. Except as stated in the

foregoing, Licensee and any transferee(s) autho-

rised by this Section may not otherwise transfer

or make available any Tait Software to any third

party nor permit any party to do so. Licensee

will, on request, make available evidence reason-

ably satisfactory to Tait demonstrating compli-

ance with all the foregoing.

Section 8 TERM AND TERMINATION

8.1. Licensee’s right to use the Software and

Documentation will commence when the Desig-

nated Products are supplied by Tait to Licensee

and will continue for the life of the Designated

Products with which or for which the Software

and Documentation are supplied, unless

Licensee breaches this Agreement, in which case

this Agreement and Licensee's right to use the

Software and Documentation may be terminated

immediately upon notice by Tait.

8.2. Within thirty (30) days after termination of

this Agreement, Licensee must certify in writing

to Tait that all copies of the Software have been

removed or deleted from the Designated Prod-

ucts and that all copies of the Software and Doc-

umentation have been returned to Tait or

destroyed by Licensee and are no longer in use

by Licensee.

8.3. Licensee acknowledges that Tait made a

considerable investment of resources in the

development, marketing, and distribution of the

Software and Documentation and that Licensee's

breach of this Agreement will result in irrepara-

ble harm to Tait for which monetary damages

would be inadequate. If Licensee breaches this

Agreement, Tait may terminate this Agreement

and be entitled to all available remedies at law or

in equity including immediate injunctive relief

and repossession of all non-embedded Software

and associated Documentation. Licensee shall

pay all Tait costs (on an indemnity basis) for the

enforcement of the terms of this Agreement.

Section 9 CONFIDENTIALITY

Licensee acknowledges that the Software and

Documentation contain proprietary and Confi-

dential Information valuable to Tait and are Tait

trade secrets, and Licensee agrees to respect the

confidentiality of the information contained in

the Software and Documentation.

Section 10 LIMITATION OF LIABILITY

10.1. In no circumstances shall Tait be under any

liability to Licensee, or any other person whatso-

ever, whether in Tort (including negligence),

Contract (except as expressly provided in this

Agreement), Equity, under any Statute, or other-

wise at law for any losses or damages whether

general, special, exemplary, punitive, direct,

134 TB9400 Installation and Operation Manual

indirect, or consequential arising out of or in con-

nection with any use or inability of using the

Software.

10.2. Licensee’s sole remedy against Tait will be

limited to breach of contract and Tait sole and

total liability for any such claim shall be limited

at the option of Tait to the repair or replacement

of the Software or the refund of the purchase

price of the Software.

Section 11 GENERAL

11.1. COPYRIGHT NOTICES. The existence of

a copyright notice on the Software will not be

construed as an admission or presumption of

publication of the Software or public disclosure

of any trade secrets associated with the Software.

11.2. COMPLIANCE WITH LAWS. Licensee

acknowledges that the Software may be subject

to the laws and regulations of the jurisdiction

covering the supply of the Designated Products

and will comply with all applicable laws and reg-

ulations, including export laws and regulations,

of that country.

11.3. ASSIGNMENTS AND SUBCONTRACT-

ING. Tait may assign its rights or subcontract its

obligations under this Agreement, or encumber

or sell its rights in any Software, without prior

notice to, or consent of, Licensee.

11.4. GOVERNING LAW. This Agreement shall

be subject to and construed in accordance with

New Zealand law and disputes between the par-

ties concerning the provisions hereof shall be

determined by the New Zealand Courts of Law.

Provided however Tait may at its election bring

proceedings for breach of the terms hereof or for

the enforcement of any judgment in relation to a

breach of the terms hereof in any jurisdiction Tait

considers fit for the purpose of ensuring compli-

ance with the terms hereof or obtaining relief for

breach of the terms hereof.

11.5. THIRD-PARTY BENEFICIARIES. This

Agreement is entered into solely for the benefit

of Tait and Licensee. No third party has the right

to make any claim or assert any right under this

Agreement, and no third party is deemed a bene-

ficiary of this Agreement. Notwithstanding the

foregoing, any licensor or supplier of third-party

software included in the Software will be a direct

and intended third-party beneficiary of this

Agreement.

11.6. SURVIVAL. Sections 4, 5, 6.3, 7, 8, 9, 10,

and 11 survive the termination of this Agree-

ment.

11.7. ORDER OF PRECEDENCE. In the event

of inconsistencies between this Agreement and

any other Agreement between the parties, the

parties agree that, with respect to the specific

subject matter of this Agreement, this Agreement

prevails.

11.8. SECURITY. Tait uses reasonable means in

the design and writing of its own Software and

the acquisition of third-party Software in order to

limit Security Vulnerabilities. While no software

can be guaranteed to be free from Security Vul-

nerabilities, if a Security Vulnerability is discov-

ered, Tait will take the steps specified in Section

6 of this Agreement.

11.9. EXPORT. Licensee will not transfer,

directly or indirectly, any Designated Product,

Documentation or Software furnished hereunder

or the direct product of such Documentation or

Software to any country for which New Zealand

or any other applicable country requires an

export license or other governmental approval

without first obtaining such license or approval.

11.10. SEVERABILITY. In the event that any

part or parts of this Agreement shall be held ille-

gal or null and void by any court or administra-

tive body of competent jurisdiction, such deter-

mination shall not affect the remaining terms

which shall remain in full force and effect as if

such part or parts held to be illegal or void had

not been included in this Agreement. Tait may

replace the invalid or unenforceable provision

with a valid and enforceable provision that

achieves the original intent and economic effect

of this Agreement.

11.11. CONSUMER GUARANTEES. Licensee

acknowledges that the licenses supplied in terms

of this agreement are supplied to Licensee in

business, and that the guarantees and other provi-

sions of prevailing consumer protection legisla-

tion shall not apply.

11.12. WHOLE AGREEMENT. Licensee

acknowledges that it has read this Agreement,

understands it and agrees to be bound by its terms

and conditions. Licensee also agrees that, subject

only to the express terms of any other agreement

between Tait and Licensee to the contrary, this is

the complete and exclusive statement of the

Agreement between it and Tait in relation to the

Software. This Agreement supersedes any pro-

posal or prior agreement, oral or written, and any

other communications between Licensee and

Tait relating to the Software and the Designated

Products.
