The Dual GAN Workstation

Not an end-device but a means to connect various kinds of end-devices to various networks.  This portable unit has been designed for armed forces in Europe.  It offers 128 kbit/s data (using two GAN terminals in parallel) for ISDN or synchronous devices, a DECT station for voice calls, a personal computer for file transfer and set up, and an adapter to enable ISDN devices to connect to synchronous encryption.
