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 (VoIP) technology.
Its Ethernet interface provides built-in network connectivity that allows the
base station to join with other base stations to form a channel group. This
network supports voice-over-IP and remote management of all base
stations via a web browser.
1.1 Series 2 and Series 1 Reciters
Ongoing product improvements have meant that the processor in the reciter
control board has been upgraded with a SMARC (Smart Mobility
ARChitecture) module that provides faster start up times, as well as
capacity for future upgrades.
Due to this hardware change, series 2 reciters require version 3.10 or later
firmware, and cannot be downgraded to earlier firmware. Version 3.10
was released on 31 July 2020 and production was changed over to series 2
during August 2020.
Series 1 control boards are now out of production.
1.1.1 Identifying a Series 2 Reciter
Series 2 reciters can be identified by the label on the back of the reciter.
Together with the type code and serial number is this graphic indicating
that this is a series 2 reciter:

TB7300 Installation and Operation Manual Description 11

The WebUI Monitor > Modules > Module Details tab also lists the series
number and hardware version of the reciter:
1.1.2 New Reciters and Repairs
Tait only provides new and replacement series 2 reciters. There is no
further production of series 1 reciters. Repairs needing a new control board
will also use a series 2 control board.
Using Series 2
Reciters in an
Existing Channel
Group
If you are adding a new or replacement reciter, Tait strongly recommend
that all the existing series 1 reciters be upgraded to version 3.10 or later, so
that all the reciters in the channel group have the same firmware version.
Failure to do so may lead to problems with channel group operation.
Reciter Repairs
Needing a
Replacement
Control Board
Series 1 reciter repairs needing a new control board will be returned as
series 2 reciters running version 3.10 or later firmware. Returned
equipment will include a notification sticker that this reciter is now series
2 and warns of possible channel group compatibility issues with reciters in
the network running older firmware.
1.1.3 Firmware Information
Series 2 reciters can only run on version 3.10 or later firmware1. There are
now separate firmware packages for series 1 and series 2 reciters as they
run different processors.
1. Later versions of series 2 reciters will require firmware versions later than 3.10.

12 Description TB7300 Installation and Operation Manual
© Tait International Limited December 2022
Upgrading from a PC using Mongoose as the local feed server from version
3.05 or earlier will display 2 versions for version 3.10 and later. The
version ending in ‘-02’ is series 2 reciter firmware:
Attempting to download -02 firmware to a series 1 reciter will fail, with a
status of ‘Error’ within a few seconds.
Upgrading from a PC using Mongoose as the local feed server with a reciter
running version 3.10 or later will select the correct firmware package for
the reciter automatically. The list of firmware presented in the lower
section is filtered by the P25/AS-IP, DMR/MPT or All radio buttons at the
top of the Tools > Firmware > Upload/Download tab WebUI page.
If you are using the direct firmware upload option, the series 1 firmware
file has the suffix .tbc and series 2 has the suffix .tbc02. File selection
has a filter for the correct file extension.
Uploading the incorrect firmware version for the series of reciter will fail
with the message ‘Information Failed Configuration’ in the Direct upload
section.

1.2 Software Applications
The TB7300 operates in both P25/AS-IP and DMR/MPT networks. Within
these networks, the base station utilizes distinct P25/AS-IP and DMR/MPT
software applications.
1.2.1 Base Station Features
The following is a list of base station features for both P25/AS-IP and
DMR/MPT/MPT software applications:
P25/AS-IP ■Fully compliant with the P25 Common Air Interface. Can therefore
interoperate with any similarly compliant radios
■Supports P25 Phase 1 conventional operation with C4FM modulation
on the transmitter
■Supports simulcast operation with P25 phase 1
■Analog conventional repeater operation
■Analog conventional simulcast operation on an IP backbone requiring
no audio calibration or training
■Analog or digital console support in analog FM and digital P25 modes
■Integrated built-in voting facility. No external voter is needed.
DMR/MPT ■Fully compliant with the DMR Tier 2 conventional and Tier 3 trunked
standards. Can therefore interoperate with any similarly compliant
radios.
■Analog conventional repeater operation
■Operation as control channel or traffic channel transceiver in MPT/
MPT-IP networks, including standalone operation
■Digital simulcast operation
DMR firmware does not support simplex operation.
Non-Application
Specific
■Can be completely managed remotely from a PC running a web
browser: configuration, alarm monitoring, fault diagnosis, syslog,
feature and firmware upgrades. Alarms can also be reported via SNMP
traps, allowing integration with an SNMP-based network management
system.
■Rugged construction with generous heatsinks and fan-forced cooling
for continuous operation from –30°C to +60°C (–22°F to +140°F)
■Supports an analog 600 Ohm connected repeater in an analog
conventional network with CTCSS or DCS subaudible signaling1

1.4 Software Application Details
1.4.1 P25/AS-IP
With the P25/AS-IP software application, the TB7300 is interoperable with
TB9400 base stations, and therefore operates in 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 a P25 conventional network, the TB7300 operates as a single or wide
area conventional repeater, with receiver voting and optional simulcast.
Dispatch connection is via three distinct interfaces:
■P25 standard DFSI connection (up to three connections simultaneously)
■Analog line
■Tait P25 Console Gateway, supporting conversion between P25 and
analog consoles with MDC1200 signaling
In an analog conventional network, the base station can operate as a
repeater with CTCSS or DCS subaudible signaling.
The base station can also operate as part of an analog conventional
simulcast network and is fully IP-connected. The base station also features
an internally integrated voter, and therefore requires no external voter.
For more information on these applications, refer to the Help and
appropriate Tait System Manual.
1.4.2 P25 Gateway Key Management
The base station has a P25 gateway function which allows an analog
console to be part of a P25 talkgroup. The gateway performs P25 vocoding
and encryption as part of the conversion between the balanced analog line
console connection and the P25 air interface. The functions supported are:
■A call profile on the WebUI defines the conversion details. The
gateway has one single call profile in this release.
■The technician defines the call type (analog or P25), the talkgroup
address, network access code (NAC), clear or encrypted operation as
part of the profile
■The gateway supports a single P25 talkgroup, with or without
encryption
■The gateway does not support individual calling, although the gateway
can send uplink individual call audio to the console (if it is clear audio
or if it has the decryption key)
■The gateway supports both AES-256 and single-DES encryption

16 Description TB7300 Installation and Operation Manual
© Tait International Limited December 2022
■Encryption and decryption are performed in the hardware. You need
reciter hardware version 6.01 to use encryption.
■The Tait Key Fill Device (KFD) can create and export keystore files.
The technician can upload a keystore file containing the encryption key
for encrypted operation. The KFD users guide (MNE-00010-xx) has
more detail.
■The gateway can store an active key and an inactive key to allow for key
change-over
For a complete introduction to key management refer to the KMF Key
Management Manual (MBA-00048-xx).
The base station WebUI help also provides more detailed information.
1.4.3 DMR/MPT
The TB7300 is designed for operation in a Tait TN9300 DMR conventional
radio network, a Tait TN9300 DMR trunked radio network, an MPT
network, or as an analog conventional repeater.
In a DMR conventional network, the TB7300 can operate as a stand-alone
repeater, or as a member of a multi-site system (under the supervision of a
DMR conventional channel controller). 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/MPT trunked network the TB7300 can operate as a control
channel or as a traffic 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 an MPT network, the TB7300 operates as a control channel or as a traffic
channel. The TB7300 operates with a trunking node, or in fallback
operation it can operate in either trunked or conventional mode.
In analog operation it can operate as a conventional repeater with CTCSS
subaudible signaling and DCS subaudible signaling.
For more information, refer to the DMR/MPT/MPT-IP System Manuals.
