Where to buy


With the wide range ISDN signaling protocols and switches support, U and S/T interface access modules, the mobile workforce can travel across the world and still enjoy the high-speed digital service without pain. The support of "async-to-sync PPP conversion" lets the DTA-128 PC Card connecting to the router-based Internet Service Providers (ISPs) at anytime anywhere with incorporation of TCP/IP software packages. Additionally, the "Multi-link PPP" protocol makes an ISDN superhighway at speed up to 128 Kbps when the applications are bandwidth critical. The DTA-128 PC Card can work exactly like an ISDN TA external box, which can run any Windows-based communication software package to hook on to the on-line services and bulletin boards.
