US Robotics ISDN TA (Model 98005100)

This is an ISDN TA sold by U.S.Robotics. In reality it seems to be designed by "FORMEL computer Flensburg GmbH", which is not too surprising as many ISDN companies were based in Germany or at least Europe, while the U.S. still was mainly focussed on analog modems.
