New Reference Boards for ISDN Applications
Siemens announced two new reference boards for ISDN applications on personal
computers. The HSCX TE Reference Board (SIPB 71525) is a low-cost, passive PC
card, which offers an option for two different line interfaces, S0 and U2B1Q, and
supports data applications using two B channels; the ISAR Reference Board (SIPB
7110) is an enhanced passive PC card adding fax and modem capabilities to the
functionality offered by the HSCX TE Reference Board.
Both boards are ready to copy and offer pre-tested designs. Both are PC boards for ISDN
Basic Rate Interface (BRI), and offer an Industry Standard Architecture (ISA) bus interface
for PC/AT/EISA systems. Siemens provides driver software and sample applications for
use under MS-DOS, MS-Windows 3.x and Windows 95.
The SIPB 71525 is an advanced solution for ISDN applications on PCs. Easy to install, it
fulfills requirements for a PC-based ISA Plug and Play Slot Card. The SIPB 71525 has
been designed to implement high-speed communication links using HDLC protocols and
to reduce the hardware and software needed for serial synchronous communications.
The SIPB 7110 offers the same functionality as the SIPB 71525, but with additional
enhancements. The new board features G3 fax support with full-duplex modem
communication, and data rate adaption according to V.110. It supports both voice and
data applications using two B channels.

Both boards come with a complete software tool package. A Common ISDN Application
Programming Interface (CAPI) driver provides a hardware-independent interface to control
the dialing and D-channel protocol. It supports North American, European, and Japanese
D-channel protocols.
The CAPI driver is ready to use with an installation/de-installation utility and includes some
extensions to control special hardware features over this interface. The package also
includes application software to interface to the CAPI. The Siemens driver structure also
supports Microsofts NDISWAN and Dial-Up networks as well as AT-command based
applications.
Both reference boards will be available in December 1996.
