Connecting radios all over the world

Damm Tetra Systems

When you are connecting a radio system to a SoftRadio dispatcher you will be using interface boxes connected to donor radios that are part of the larger radio net.

This is no longer needed for DAMM Tetra systems. In cooperation with Semco Maritime we have created a new software option that allows a SoftRadio dispatcher to connect directly to the DAMM Tetra infrastructure via a TCP/IP connection.

The DAMM system appears in Mimer just like other radios do. Private calls to and from the operator as well as group calls and messages can be handled.

All other Mimer devices are available simultaneously, like Airband or Marine radios as well as phones and intercoms.

And the DAMM private calls and talk group calls works just like any Mimer radio so they can be crosspatched to other radios.

Examples of use:

  • Local use when the operator is located where the Tetra system is.
  • Remote use where a dispatcher at one location want to talk to radio users at a different location
  • CrossPatch between Tetra and other two way radios, like analogue, Marine, DMR or Airband.
Mimer SoftRadio

Please note that the Damm Interface for SoftRadio is only sold through
Semco Maritime
in Denmark.

It can not be bought directly from LS Elektronik.

Functionality

We have tried to reflect the operators most important needs when monitoring and talking to the Tetra users. All those functions are easily accessible, while other functions are hidden or not even implemented since they are just in the way of daily use.

All the basic Tetra functionality are there:

  • TalkGroup select and listen

  • List of logged on users

  • Contacts list and calls

  • SDS and status, send and receive

  • Set up of DGNA Groups

  • Positioning together with Mimer MapView

Operation

The operator will see a GUI that looks and behaves very much like standard SoftRadio does for other radio types.

Each connected Talk group will be represented with a device panel that lets the operator make calls and answer calls.

All groups can be monitored in parallel and at the same time as other radio communication.

When there are settings to do, or a message to send, device windows, much like the virtual control heads for radios, can be opened.

Screen shots

SoftRadio with Airband, MarineBand and Damm Tetra with four talk groups

In the standard GUI for SoftRadio you will see one device panel for each attached talk group and one device panel for the system itself.

In this example also one marine radio and one airband radio are connected to the same GUI.

Damm Dispatch window

Opening the window of the systems device panel shows a list of attached radios, a history list of calls and a history list of SDS and status messages.

Here you also choose radios for private calls and for messages.

Managing the Talk Groups

Each operator can choose which talk groups to monitor through an easy to use graphic interface.

Send SDS message menu

When sending an SDS message, the operator can choose different levels of reports on the message. In the history list this will be reflected by different icons depending on the messages status.

Message templates

Templates can be set up for messages that are sent often.

Call set to emergency level

Both incoming and outgoing calls can have different priorities whith emergency as the highest.

This will be reflected with a pink colour and incoming emergency calls will get an audible signal so that the operators does not miss the call.

System examples:

Two operators working with both Tetra, Airband and Marine radios

Example with two operators connected to one Damm system and two radios for AIrband and Marineband communication

Multi Systems

Example with several Damm systems connected to several operators
