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 firmware-based configurability and
operation, digital signal processing, and Voice over IP (VoIP) technology.
The TB9400 combines industry-leading digital voice quality with rugged
design specifications and intuitive user interfaces. These products are
designed to meet the needs of the public safety and public service sectors,
and professional radio users.
The ability of the base station to link stations using standard Internet
Protocol communications, and to add features through firmware options,
ensures that DMR and P25 systems designed with the TB9400 are scalable
in both size and functionality.
The base station’s Ethernet interface provides built-in network
connectivity, which allows it to join with other base stations to form a
channel group. This network supports VoIP and remote management of all
base stations via a web browser.
The TB9400 operates as the following:
■An IP connected transceiver in trunked DMR or MPT networks
■An IP connected transceiver in trunked simulcast radio networks
■An IP connected transceiver in non-simulcast multi-site networks
■An IP connected transceiver in digital conventional simulcast networks
■An IP connected repeater in DMR conventional networks
■An analog 600 Ohm connected repeater in an analog conventional
network with CTCSS or DCS subaudible signaling
■An IP connected transceiver in P25 trunked networks
■An IP connected repeater in analog or P25 conventional networks
■A data transceiver for custom digital modulations with the unbalanced
line audio interface

12 Description TB9400/TN9275 Installation and Operation

■P25 Phase 1 FDMA, or 6.25kHz equivalent P25 Phase 2 TDMA
■An IP connected transceiver in analog conventional simulcast networks
The TN9275 P25 analog gateway provides a subset of P25 conventional
operation when compared to the TB9400 base station. It provides all of the
functions of a channel group master with analog, P25 and dual
conventional operation, but it does not have an RF transceiver.
Physically, the gateway module is similar to a reciter without the RF
transmit and receive connectors.
The gateway and base station share the same firmware. The first firmware
release supporting the TN9275 operation is 3.45.00
In this manual, where it says “base station” or “reciter”, it should also be
understood to generally refer to the TN9275 gateway, with the exception of
any RF and transceiver functions.
1.1 Series 2 and Series 1 Reciters
Series 2 reciters have been in production since 2020, and replace series 1
reciters, which are no longer in production.
Refer to the latest software release note for series 2 hardware and firm-
ware compatibility information.
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:

TB9400/TN9275 Installation and Operation Description 13
© Tait International Limited May 2023
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
There are separate firmware packages for series 1 and series 2 reciters as
they run different processors.

14 Description TB9400/TN9275 Installation and Operation
© Tait International Limited May 2023
Upgrading version 3.05 or earlier from a feed server 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 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.
Refer to the latest software release note for series 2 hardware and firm-
ware compatibility information.
1.2 Firmware Applications
The TB9400 is interoperable with both TB7300 and TB9300 base stations,
and therefore operates in both P25/AS-IP and DMR/MPT networks.
1.2.1 Base Station Features

1.3 Firmware Application Details
1.3.1 P25/AS-IP
The TB9400 is designed for operation as a transceiver in P25 trunked and
trunked simulcast (Phase 1 or Phase 2), P25 conventional networks and
analog conventional networks. It operates as a stand-alone 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 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.
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.
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.

TB9400/TN9275 Installation and Operation Description 17
© Tait International Limited May 2023
With P25/AS-IP operation, channel groups can comprise a mixture of
base station types. TB9400 and TB7300 base stations are fully compat-
ible and have identical timing in simulcast operation.
The TN9275 analog gateway supports all the channel group master
functions of P25/AS-IP simulcast and multicast networks that do not
directly involve the RF transceiver. This includes: the voter, the analog line
interface, DFSI interfaces, the console gateway interface, simulcast
transmit control and timing.
For more information on these applications, refer to the Help and
appropriate Tait System Manual. See “Associated Documentation”.
1.3.2 P25 Gateway Key Management
The base station and TN9275 P25 analog gateway support the 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:
■Acall 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
■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.

18 Description TB9400/TN9275 Installation and Operation

1.3.3 DMR/MPT
The TN9275 analog gateway does not support DMR/MPT operation.
In a DMR conventional network, the base station 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
concurrent logical channels (timeslots) for each radio frequency (physical
channel), the same frequency can be accessed simultaneously, 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 trunked network, the base station can operate as a traffic channel
or a control channel. With two logical channels for each radio frequency, a
single base station can provide two traffic channels, two control channels,
or both a traffic channel and a control channel.
In an MPT network, the base station operates as a control channel or as a
traffic channel. The base station operates with a trunking node or in
fallback operation. MPT fallback provides trunking and conventional
operation.
In analog operation, the base station operates as a conventional repeater
with CTCSS or DCS subaudible signaling.
With DMR/MPT operation, channel groups can comprise a mixture of
base station types. TB9400, TB7300 and TB9300 base stations are fully
compatible and have identical timing in simulcast operation.
For more information, refer to the DMR System Manual (MNB-00010-xx).

1.4 Modules
The base station consists of a subrack with up to two transmit/receive
channels, or up to four receive-only channels.
The single PMU (power management unit) supplies and manages power to
the whole subrack (refer to “Theory of Operation” on page 31). One reciter
and one PA (power amplifier) are needed for each transmit/receive channel.
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 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 sections provide brief descriptions of the base station
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. A module’s position in the subrack is defined by the associated
interconnect board socket, which connects the module to the system
control bus.

20 Description TB9400/TN9275 Installation and Operation
© Tait International Limited May 2023
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, an 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

The base stations have different front panel ducting arrangements
depending on PA type and power. Front panels may not be interchange-
able.
The microphone input and speaker are not currently used.
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.
A TN9275 gateway module is physically similar to a reciter but does not
have transmit or receive connectors.
