1Introduction
1.1 Overview
This document contains information about installation, settings, and operation of
the DVI-100 TETRA Radio Modem. This includes practical guidance relating to
antenna selection and installation, operating range, extension modules, software
support, etc.
1.2 Safety Precautions
This equipment transmits radio waves in the frequency range 380 to 470 MHz or -800
MHz. Under certain circumstances, these radio waves could be harmful to any living
being or electronic equipment near it. Care should be taken to ensure that the radio and
antenna systems are installed and commissioned only by trained persons.
This radio equipment should not be used in life support systems or in safety systems
without our prior written permission.
1.3 Disclaimer
We have carefully checked the contents of this document, and the hardware and
software described in it, for compatibility. We cannot however exclude possibilities of
deviations and cannot guarantee complete conformity of the document with the
equipment it describes. If any corrections or improvements are to be made, they will be
taken into consideration in the next edition of this document.
Important instructions are marked by the expressions "Important", "Note" or
“Caution!”. These should be carefully observed.

1.4 General description
The DVI-100 (Digital Voice Interface) will be attached to a TETRA Network in the
same way as a normal TETRA hand portable, and it can be a Member of up to 25
talkgroups. When it receives a voice call, rather than decoding the digitally coded
ACELP data stream into analogue audio and feeding it to the Loudspeaker, it is sent as
a digital (UDP) data stream to its IP port. Connecting two DVI-100s back-to-back with
each device connected to a different TETRA network (which could be different
infrastructure manufacturer, different frequency bands or geographically separated),
allows the networks to be “interconnected” based on group calls, status messages, and
short data messages. As the voice data stream is not converted back into an analogue
signal at any time, the voice quality has the same brilliant quality as received with a
TETRA hand portable.
The DVI-100 can be used in each of the three following described scenarios.
1.5 Application scenarios
1.5.1 Back to Back Operation
With two DVI-100’s logged into different TETRA networks and by connecting them
via Back-to-Back IP, an easy ISI for voice and SDS transmission can be implemented.

1.5.2 Connected to the iPhone or a Computer
Using the DVI with IP, the voice data can easily be sent to, or received by, a remote
application, potentially running on any type of device. This allows the voice call to be
bridged between the TETRA infrastructure and another device. An iPhone application is
available, as well as Java based software for Mac or Windows Computers. This
application can be useful, if a user needs to talk or just listen to a group within a
TETRA network, even when they are out of coverage of the TETRA network.

1.5.3 Connected by IP directly to a TETRA switch
The PTX Protocol developed by the University of Dortmund and Piciorgros GmbH is
license free and can be implemented to an interface device (PC) or directly into a
TETRA switch. So an Inter System Interface (ISI) for voice and data based on groups
can easy be implemented.

1.5.4 TETRA MircoSPOT with DVI-100 in DMO mode
This configuration can be used to create a local TETRA access point (MicoSPOT)
which operates in DMO mode. The DVI-100 in DMO mode is connected by an IP
connection to another DVI-100 in server mode, which is attached to a TETRA network.
All TETRA terminals in DMO mode and in range of the DVI-100 MicroSPOT can
access the configured group(s) of the trunked TETRA network by using voice, SDS and
status communication.
Sample applications for the MicoSPOT can be improving inhouse coverage or covering
white spots inside a TETRA network. By using a reliable mobile IP link (3G or LTE)
mobile forces can use the TETRA network even in uncovered areas.

2Access the embedded Web server
The whole configuration is done by accessing the internal web server of the DVI-100
and changing certain parameters using the user-friendly interface. The first to do is to
integrate the device into the local network. The network is supposed to use addresses of
the type 192.168.0.xxx.
The DVI-100 itself is available at the address 192.168.0.199. It must be sure that the
network has the right range of addresses and there is no other device with this address
connected to the network.
Accessing the interface the first time, a username and a password are required. The
login is registered to the name 'user' and the password 'user'. The password can be
changed as one of the following steps.
In registered state the user can see a menu on the left hand side, a content window on
the right and a footer containing selected information on the bottom.

3Register the DVI-100 to the TETRA Network
In factory default state there is no information available for the device to enter the
TETRA network. This is why the TETRA parameters have to be configured before the
device is able to register on the network.
3.1 Basic TETRA parameters
The TETRA parameters configuration can be accessed in "TETRA >> Parameters"
First, the operation mode must be selected between TMO mode and DMO mode. The
TMO mode (trunked mode) is used when the DVI-100 should be attached to an existing
TETRA infrastructure while the DMO mode (direct mode) should be used to create a
local MicroSPOT in areas without TETRA coverage.
In both modes, the basic parameters are the ISSI, the MCC and the MNC. The MCC
and MNC must match the corresponding values of the TETRA infrastructure (TMO
mode) or the TETRA terminals which needs to communicate with the DVI-100 (DMO
mode). The ISSI must be a unique subscriber number which must be configured in the
TETRA infrastructure in TMO mode.

V1.01 page 10of 24
3.2 TMO mode parameters
If the TMO mode is configured, at least one scan range for the lookup of base stations
of the TETRA network must be configured. Here, the value of the first (lowest) scan
frequency must be inserted. Alternatively if no frequency information is available, a
TETRA “Channel” can be selected at “Select input” and the number of the first channel
can be inserted in combination with the networks offset value. The range of scanned
channels can be varied up to a maximum value of 400.
To apply the changes the button “Apply” has to be pushed. Following a button appears
underneath to restart the device. After the restart the device reprograms the internal
TETRA modem with the new parameters. This can be seen when the numbered LEDs in
the RF display are toggled from the right to the left.
Next the modem starts to log in the network. The RF display runs from the right to the
left again. This means that it is essential to observe the LED movement at least twice
before the device is registered in the network using the new parameters.
When registered the RF display shows the field strength of the device. Otherwise it
starts consecutive tries to access the network.
