Introduction

T.Bridge supports integration with mobile two-way radios connected through the analogue audio IN

and OUT interfaces (hence the Bridge name). Technically, it could be almost any radio with analogue

audio input and output (see hardware requirements for more information).

T.Bridge uses voice activity detection to determine if someone is speaking over the connected radio

and transmits the sound from the radio to TASSTA network and vice versa.

IMPORTANT:

Due to the nature of the connection, the bridging is only limited to voice transmission between the

networks.

T.Bridge also supports Deditec USB relay module for controlling and communicating with external

devices.

This document describes the deployment and configuration of T.Bridge service for connecting to

mobile radios through the analogue audio interface.

Required hardware

•2 GHz or faster processor.

•8 GB of RAM.

•Minimum 250 MB of available storage space.

•Network card.

•Audio interface with input and output jacks.

•A mobile radio with analogue audio input that meets the following requirements:

▪The radio must support voice operated switch (VOX) function.

VOX is used as an automated push-to-talk switch that turns on when a user speaks and off

when a user stops speaking.

▪Voice encryption must be disabled or not supported.

•An optional Deditec USB relay module (when working in relay mode).

Deployment

T.Bridge operates in the background as a service without a graphical user interface. It connects to

T.Lion server via a standard WAN/LAN and uses a third-party API to communicate with an external

PMR network.

Once the bridge between T.Lion and the external network is established, users from both systems can

transparently communicate with each other in shared channels. All TASSTA clients are supported,

including T.Rodon dispatcher console and T.Mugen web client. If recording is enabled for the server,

user activity in TASSTA and bridged networks is recorded and can be accessed through TASSTA

clients and T.Recorder. The history includes calls and messages, as well as location data, where

available.

Installation package structure

T.Bridge 4wire is distributed as a ZIP archive. The following table contains a list of key TASSTA

components and drivers mentioned in this document. All paths are based on the root directory of the

installation package.

Description

delib\delib_install.exe

DELIB Driver Library installer version 2.26, 32-bit.

delib\delib_install_x64.exe

DELIB Driver Library installer version 2.26, 64-bit.

Installing T.Bridge

1. Unpack T.Bridge distributive to %ProgramFiles%\TASSTA\Bridge folder.

NOTE: You can choose an alternative installation folder.

2. Modify the configuration.

3. Install and run T.Bridge service.

NOTE:

If prompted, allow T.Bridge to communicate through Windows Firewall.

Installing DELIB Driver Library

T.Bridge 4wire requires DELIB Driver Library to work correctly. The distributive is located in delib

subfolder of T.Bridge installation package.

To install DELIB Driver Library:

1. Go to T.Bridge installation folder (usually, C:\Program Files\TASSTA\Bridge ) and open delib

subfolder.

2. Run delib_install_x64.exe.

3. Select DELIB Driver Library component and click Next.

4. Click Install.

Updating T.Bridge

1. Stop T.Bridge service.

2. Unpack T.Bridge distributive to the folder where the previous version is installed, overwriting the

existing files.

IMPORTANT: Be careful not to overwrite the active configuration!

3. Start T.Bridge service.

T.Bridge Windows service

T.Bridge is a Windows service which is automatically started at the system startup and constantly runs

in the background. The service operates under Local system account.

The default service name is TASSTA Bridge.

Installing T.Bridge service

IMPORTANT:

Make sure T.Bridge is not already running as a service before following the instructions below.

1. Download the latest release of NSSM.

2. Extract NSSM archive under C:\Program Files. The latest release (version 2.24) will be unpacked

under C:\Program Files\nssm-2.24.

3. Open a command prompt as Administrator.

4. Execute a command:

"%ProgramFiles%\nssm-2.24\win64\nssm" install "TASSTA Bridge"

"%ProgramFiles%\TASSTA\Bridge\bridge3.exe" "-cfg bridge.cfg"

NOTE: This command assumes that T.Bridge is located in the default installation folder

(C:\Program Files\TASSTA\Bridge ) and the configuration is stored in the file bridge.cfg. Adjust

the command line parameters if necessary.

5. Start TASSTA Bridge service.

You can do it from the command line: `"%ProgramFiles%\nssm-2.24\win64\nssm" start "TASSTA

Bridge".

Managing T.Bridge service

1. Open Services from Administrative Tools.

Alternatively, execute services.msc from Run.

2. Locate TASSTA Bridge in the list.

To start T.Bridge service

1. Select TASSTA Bridge service.

2. Click Start Service button in the toolbar or right-click the service and click Start in the context menu.

To restart T.Bridge service
