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.

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.

1.3 Mechanical Assembly

This section illustrates the main mechanical components of the base station.

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

station. The subrack has six slots, numbered from right to left as viewed from the front of the subrack. The PMU occupies slots 5 and 6, with the reciter and PA pairs to the right of it in slots 1 to 4. Each PA is mounted vertically with its heatsink facing its associated reciter. The PMU and each reciter/PA pair have their own cooling fans.

The front panel can be easily removed from the subrack by undoing two quick-release fasteners. Refer to “Replacing Modules” on page 106 for more details.

1.4 Frequency Bands and Sub-bands

Much of the circuitry in the base station is common to all frequency bands, and is therefore covered by a single description in this manual. In some cases the descriptions refer to specific bands or sub-bands, and these are identified with the letters listed in the following table.

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.
