The end of 2G and 3G networks is approaching. Transition seamlessly to modern 4G with the 2N EasyGate IP. Connect an analogue elevator communicator to the gateway. This will ensure voice or data (VoIP) communication via a mobile network with an operations centre. If you are using an old mobile network for emergency communication, you can continue to do so. When you're ready to transition to 4G, all you'll need is a single click in settings. The gateway also supports VoIP (SIP) technology, which is the only technology to guarantee reliable transmission of a DTMF signal.
