Assured ISDN Inter-operability

With the wide range ISDN signaling protocols and switches support, the mobile workforce can travel across the world and still enjoy the high speed digital service without pain.

Universal Compatibility

The support of "async-to-sync PPP conversion" lets the TA128 Intelligent ISDN TA 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 TA128 Intelligent ISDN TA PC Card can work exactly like an ISDN TA external box, which can run any Windows-based communication software package, such as Windows 95 Hyperterm, Procom Plus, etc., to hook on to the on-line services and bulletin boards.

Compliant to Software Standard

The multiple Application Programming Interface (API) and driver support guarantees the TA128 Intelligent ISDN TA PC Card to be compatible with all popular Windows-based operating environments, including Windows 98, Windows 95, Windows NT, Windows 2000, Windows XP and Applications.
