Mimer SoftLine gives you the ability to create a virtual four wire line and more.....
- Do you use leased lines to send audio over long distances?
- Do you use modems over leased lines to send data?
- Do you have a need to send logic I/O:s over long distances?
This can be solved with two Mimer SoftLine Network Interfaces connected together over the Internet or your own LAN.
When connecting two Network Interfaces together over a network or over the Internet, a virtual four wire audio line is created. Along with the audio line you get an RS232 connection and some I/O-ports.
This can be useful to connect old base stations or dispatchers to radio switches. It can also be used for alarms or totally different types of connections.
Leased lines are expensive today, specially if they are long. Connecting the audio over the Internet instead will drastically reduce costs.
Mimer SoftLine can also be used to connect the standard control head of a radio to the radio at a long distance. For example if you do not want to operate your radio via a PC as you would usually do in Mimer SoftRadio. In this way a radio can be remotely controlled over the internet from a standard control head. Read more about this solution at the bottom of this page.
With the SoftLine connection you get:
- One virtual 2 or 4-wire line for audio
- One RS232 transparent data connection
- Two logic I/O:s
One of the I/O´s can also be used for indication that the IP connection is active.
Cross patch Radio terminals with Mimer SoftLine
Sometimes it is needed to connect two radios together back-to-back in order to cross patch between different types of radio systems.
There are also systems that needs to patch two radios together that are placed at different radio sites. They can be of the same radio type and system or they can be of totally different types.
Below is an example of this. Using SoftLine to cross connect between a Tetra terminal and an Airband radio at different sites that are connected via IP.
All audio that comes in on one radio will be rebroadcasted on the other. Making a cross patch between Airband and Tetra and making a geographical jump from one radio site to another.
The radios can also be installed at the same site with just a TP patch cable between the two network interfaces.
See our video describing the patching of a Kenwood digital radio and an Icom Airband radio through SoftLine. Link to video.
Alternative Cross Patches
Remote connection of a radio
If you for example need to connect a modern radio to a legacy radio system. You can use a 4-wire interface at one end and a radio purpose built interface at the other end.
All audio that comes in on the remote radio will be transferred into the legacy radio system. And audio out from the old radio system will be transmitted on the remote radio.
There is no need for PTT information from the legacy radio system, the interface will react to the audio level and key up the remote radio.
Mimer SoftLine as a remote user - Speaker and Microphone
In this example a fixed mobile radio is remote controlled from a desk top microphone and speakers.
It is just a simple connection with audio and PTT so that you can transmit and receive on a radio that is “anywhere”. Connected over a local LAN or across the world over the Internet.
Mimer SoftLine as a remote user - Standard Control Head
Remote control your Sepura or Motorola Tetra radio, Icom marine radio or Motorola GM-series radio, using the standard control head, for up to 150 meters from the radio, or longer using fibre cable or the Internet.

Instead of a leased line
Connections that earlier required a leased line can be set up with the help of two SoftLine units.
The radio and the console can be “anywhere” as long as there is IP inbetween.
If you would like to get rid of the old operator console and use a PC instead, please see our Mimer SoftRadio products.
