US Robotics ISDN TA (Model 98005100)¶
This is an ISDN TA sold by U.S.Robotics.
In reality it seems to be designed by Stollmann E+V 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.
|Supply Voltage||5V AC (or DC), positive pin next to RJ45|
