Yes, it has been done. We, sony, has a unix-based workstation, it has the ISDN Interface board. (We got an apploval of PTT of Japan.) Our machine installed this board can be used as a TCP/IP gateway between Lan and ISDN. We will demonstorate TCP/IP over ISDN at InterOP '90. If anyone is interested in it, please stop by at Sony booth. Takashi Hagiwara (Hagiwara@Sm.Sony.Co.Jp)
