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 © Tait Limited June 2016

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 870 MHz)

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.

12 Description TB9400 Installation and Operation Manual

Front Panel

The front panel is mounted onto the subrack with two quick-release fasteners. It incorporates the indicator LEDs, four-line LCD display, user controls, ambient temperature sensor and cooling fans.

The indicator LEDS allow some monitoring of the operational status of the base station. The user controls and display allow the technician to configure the IP address of each module. Refer to “Front Panel” on page 40 for more information.

The microphone input and speaker are not used in this release of the TB9400.

Reciter The reciter module comprises the receiver, exciter and digital control

circuitry. The reciter provides the Ethernet interface and system inputs and outputs.

Receiver modules (receive-only reciters) are not fitted with the transmit circuitry or front panel SMA connectors, and are physically unable to transmit.

Power Amplifier

The PA amplifies the RF output from the reciter and is available in 50W and 100W models.

The 50W model mounts vertically in the subrack, while the 100W model mounts horizontally as it has a wider heatsink. The 100W PA is also fitted with an airflow duct.

50W PA 100W PA

Both models are designed to operate on the 28 VDC 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 48 VDC 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.

1.4 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.

Frequency Identification Frequency Band and Sub-band 50W 100W Receive-only

B band B3 = 148MHz to 174MHz

H band H1 = 400MHz to 440MHz

H2 = 440MHz to 480MHz

K band K4 = 762MHz to 870MHz

a. The actual frequency coverage in this band is:

Transmit: 762MHz to 776 MHz, and 850 MHz to 870 MHz Receive: 792MHz to 824MHz

In Brazil, for K band, the TB9400 is considered to be configured as a base station with retransmission of receive frequencies.

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 CTCSS

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.

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)

P25 Common Air Interface (TBAS050)

P25 Trunking Operation (TBAS056)

Central Voter (TBAS061)

Simulcast (TBAS062)

Linear Simulcast Modulation (TBAS065)

A base station with this license can operate as a repeater in an analog conventional network.

Allows the base station to go into Online mode. Base stations are always provided with this license.

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.

P25 and analog. This feature allows a base station to act as a central voter.

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

to a P25 Phase 1 simulcast or analog simulcast network in the central voter of a simulcast channel.

. It is also required

P25 only. Allows the base station to transmit using the LSM modulation scheme

. 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)

20 Description TB9400 Installation and Operation Manual

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.

P25 Phase 2 Simulcast (TBAS069)

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

to a P25 Phase 2 simulcast network of a P25 Phase 2 simulcast channel

. It is also required in the central voter

. 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.

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.

Ethernet Interface

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.

Specific configuration settings for dual base stations are described in

“Recommended Configuration Settings” on page 59.

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 powered by either the AC (mains) or the DC (battery) supply. The base station will default to the AC supply if both supplies are provided. If the AC supply becomes unavailable, a seamless changeover from the AC to DC supply takes place, providing that the battery voltage is above the configured minimum startup voltage. You can use a web browser to check whether the base station is running on battery or mains power.

DC Operation When the base station is running off the DC supply and the battery voltage

falls below the configured minimum, the base station will enter battery protection mode to protect the battery and base station equipment. The standby power supply card maintains the power to the PMU microprocessor, while the rest of the PMU is shut down. When the battery voltage rises to the configured startup setting, power is resumed to the DC supply. Refer to “PMU Operation on DC Input” on page 28 for more detailed information.

Auxiliary Power Control

Distribution Figure 1.8 shows how power is distributed to modules in the subrack. The

The output from the auxiliary power supply board can be used to power other site equipment. The maximum output is 40W.

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

Battery Protection 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.

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.

PMU Temperature Current Fan Duty Cycle

32 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 106). In all cases follow safe lifting practices.

2.1.2 Lethal Voltages

Warning

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.

The PMU contains voltages that may be lethal. Refer

48 Operation TB9400 Installation and Operation Manual

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.

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

Notice The cooling fans are mounted on the front panel and will only operate when the panel is fitted correctly to the front of the subrack. To ensure adequate airflow through the base station, do not operate it for more than a few minutes with the front panel removed (e.g. for servicing purposes).

4.1.4 Ambient Temperature Sensor

The ambient temperature reading for the base station is provided by the temperature sensor located on the front panel circuit board.

50 Installation TB9400 Installation and Operation Manual

4.1.5 Cabinet and Rack Ventilation

The cooling airflow for the base station enters through the front panel and exits at the rear of the subrack. For optimum thermal performance, the heated air that has passed through a base station must not be allowed to reenter the air intakes on the front panel. Any space at the front of the cabinet not occupied by equipment should be covered by a blanking panel. Refer to Figure 4.1 on page 52.

To allow enough cooling airflow through a cabinet-mounted base station, we recommend the following:

■ an area of at least 23in

holes in front of the air intakes for the fans for each subrack; for example, thirty 0.25x3.3 in (6 x85mm) slots will allow the recommended airflow

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

(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.

(150cm2) of unrestricted ventilation slots or

Auxiliary Extractor Fans

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.

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

■ if there are fewer than six fans, you must remove them and ensure the

94.2 ft

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).

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.

port number in this range could cause the base station to malfunction.

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.

4.4.6 Tuning the Reciter and Receiver

In this section “reciter” also applies to the receiver module (receiveonly reciter).

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

receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 2MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency.

The receiver in the B3-band reciter covers the 148 to 174MHz frequency band. This is split into two sub-bands: 148 to 159MHz and 159 to 174MHz.

Each sub-band has its own helical filter (shown in Figure 4.3 below) which is electronically switched in or out of circuit depending on the frequency programmed into the reciter. The bandwidth of these helical filters is approximately ±1.5MHz.

Figure 4.3 Identifying the B-band receiver front end helical filters

B3: 159 to 174MHz

B3: 148 to 159MHz

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

Remove the reciter from the subrack and reconnect the system control bus cable to power up the module.

Tait can provide extender cables (TBC Reciter Power Cables) to enable tuning with a subrack or from a bench power supply. To order these, the part number is T01-01150-0001.

1. Log in to the reciter and select Monitor > Interfaces > RF Interface. For information on connecting directly to the reciter, refer to

“Connecting a Networked PC to a Base Station” on page 86.

2. Feed a signal at the currently tuned receive frequency and at a level of –80dBm into the reciter’s RF input. Check that the RSSI reading on the RF Interface page is –80dBm ±1 dB. 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 ± 1 dB. 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 tool

, adjust the correct helical filter for the new frequency (as shown in Figure 4.3) to obtain a peak RSSI reading. This reading should be within 1dB of the reading at the previous frequency.

Adjust the center resonator of the filter first, followed by the two outer resonators (in any order). Each resonator should require approximately the same amount of adjustment when tuning.

A change in frequency of 5MHz requires approximately one turn of the tuning slug. If tuning to a lower frequency, adjust the slug in (clockwise); for a higher frequency, adjust the slug out (counterclockwise).

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

0.5MHz above and below the required frequency and check that the RSSI reading does not drop by more than 0.5dB from the reading at the required frequency.

7. Recalibrate the RSSI at the new frequency (Calibrate > Reciter > RSSI).

If you wish to confirm the accuracy of the tuning procedure, carry out a sensitivity measurement at the new frequency.

H-Band

Before the base station is installed on site, you may need to tune the receiver front end. The receiver front end requires tuning if the receive frequency is shifted more than 5MHz away from the previously set frequency, or the RSSI level of the new frequency is more than 1dB lower than the RSSI level of the previously set frequency.

Tait can provide extender cables (TBC Reciter Power Cables) to enable tuning with a subrack or from a bench power supply. To order these, the part number is T01-01150-0001.

The receiver in the H-band reciter covers one of the following frequency sub-bands, depending on the model:

■ H1 - 400 to 440MHz

■ H2 - 440 to 480MHz.

Each sub-band uses the same helical filter (shown in Figure 4.4 below). The bandwidth of the helical filter is approximately ±5MHz.

Figure 4.4 Identifying the H-band receiver front end helical filter

H-band helical filter

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 ±1 dB. Note this reading.

4. Set the reciter to the new receive frequency.

64 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 ±1 dB. 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 tool

, 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.

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

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.

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 synchronized, which will assist the diagnosis of faults.

Synchronization requirements are more stringent with the introduction of simulcast and with TDMA in Phase 2. See Technical Note TN-2411a Providing Synchronization to Tait Networks.

4.5.2 Equipment Required

It is beyond the scope of this manual to list every piece of equipment that an installation technician should carry. However, the following tools are specifically required for installing the base station:

■ Pozidriv PZ3 screwdriver for the M6 screws used in the DC input

terminals on the PMU; M6 (0.25in) screws are also used to secure the subrack to the cabinet in factory-assembled systems

■ 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 (28 kg) 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.

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

Figure 4.7 Auxiliary support bracket

Notice Yo u 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.
