1 Description

The Tait TB7300 base station is a robust state-of-the-art digital fixed station that combines Tait’s proven strengths in reliability and high performance with software-based configurability and operation, digital signal processing and voice-over-IP technology.
The base station is designed for operation in a Digital Mobile Radio (DMR) Tier 2 conventional or Tier 3 trunked 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 DMR systems designed with the TB7300 are scalable in both size and functionality.
The TB7300 can also operate as a simple, conventional analog repeater with CTCSS
The base station combines industry-leading digital voice quality with rugged design specifications and intuitive user interfaces. These products have been designed to meet the demanding needs of professional radio users.
Its Ethernet interface provides built-in network connectivity. This network supports voice-over-IP in DMR networks, and remote management of all base stations via a web browser.

1.2 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
B band B3 = 148MHz to 174MHz

1.3 Applications

The TB7300 is designed for operation in a Tait TN9300 DMR Tier 2 conventional radio network, a Tait TN9300 DMR Tier 3 trunked radio network, or as an analog conventional repeater.
In a DMR Tier 2 conventional network it can operate as a stand-alone repeater, or as a member of a multi-site system (under the supervision of a DMR conventional node). Since DMR provides two logical channels (timeslots) simultaneously for each radio frequency (physical channel), two users can alternately access the same frequency, one in each timeslot. Base stations on different sites can be linked together to form channel groups. A base station can support two channel groups, one in each timeslot.
In a DMR Tier 3 trunked network it can operate as a traffic channel or a control channel. With two logical channels for each radio frequency, a single TB7300 base station can provide two traffic channels, two control channels, or both a traffic channel and a control channel.
In analog operation it can operate as a conventional repeater with CTCSS subaudible signaling
For more information, refer to the DMR System Manual.

1.4 Licenses

Some operational functions of the base station are controlled by licenses. These functions will not work unless you purchase the appropriate feature license and enable the feature set controlled by that license. The feature sets currently available are listed below.
The base stations in a Tait DMR Tier 3 Network are controlled by a node (DMR trunking controller). The TB7300 is compatible with two types of Tait node: Express and Access. Each type of node has different capabilities. Refer to TN-2134 for more information.
A base station operating as an analog conventional repeater needs the TBAS301 license.

1.5 Theory of Operation

The RF input is fed directly to the receiver board, while the RF output is via the exciter and PA boards. The control board also receives signals from, and sends signals to, the system interface, the Ethernet interface, and the front interface (see Figure 1.1).
The Ethernet interface carries voice over IP and also allows maintainer access via a web browser.

The control board carries out signal processing and has overall control of the base station.
The control board converts information between analog and digital and controls the maintainer’s access via the Ethernet interface. It performs the air interface signal processing for digital DMR operation, gives the base station an identity as a network element, and provides the physical connections for the Ethernet and system interfaces.

Ethernet Interface
Digital DMR signals from the receive RF interface pass through the digital receiver and DMR modem to the control software in the RISC processor. The control software passes the signal through the Ethernet interface to the node controller.
Input to the Ethernet interface is from the node controller. This input is processed by the RISC and passed through the DMR modem to the transmitter.
Analog FM signals from the receive RF interface pass through the digital receiver and are converted to G.711 before being modulated and retransmitted.

1.5.2 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.
TB7300 Installation and Operation Manual Description 15 © Tait Limited December 2015

1.5.3 Power Supply

The supply interface board accepts a nominal 13.8VDC input and distributes it to the PA board and front interface board. The front interface board then feeds the receiver, exciter and control boards. The supply interface is fused at 15A.

1.5.4 Front Panel Fans

The base station is equipped with three fans. One fan is for the receiver, exciter and control boards, and the other two fans are for the PA. Front panel fans do not operate continuously, but are switched on and off as needed. The fans can also be temporarily enabled for test purposes via the web interface.
When the base station is powered up, the fans turn on until the main software fully boots.

2.5 Device and Network Security

If this radio network equipment is used for mission-critical applications, it is important to be able to ensure security and continuity of operation. For IP-network-connected equipment, it is also important to ensure that this equipment is not a means of compromising other equipment in the network.
All network elements should be physically secured, where possible. This includes the use of locked cabinets and locked rooms. Seals on connectors can also provide a visual indication of unauthorized tampering.
Tait recommends that all network and audio connectors should be sealed with the stick-on type of seal. The seal should reveal if any of the connectors have been unplugged, or if any unauthorized equipment has been plugged in.
The seals should be difficult to remove without breaking, and should bridge between the cable and equipment side (plug and socket) of the connection.
Seals should cover any unused network or audio sockets. This includes the Ethernet connector on any adaptor front panels, any spare switch ports, and the console port on the router and switch.
The seals should 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.
