Features
V!CAS
• Included on your BinTec ISDN Companion CD you’ll find the RVS-
COM lite communications software for Windows 95 and NT, which
is a good and useful example for the power of CAPI applications.
• Router—use your V!CAS for routing IP or IPX packets received via
ethernet from your PC to your company LAN over the ISDN, and
vice versa.
• Bridge—use your V!CAS to connect two LANs.
• Remote configuration—configure your V!CAS from a remote site us-
ing the isdnlogin program (please refer to the Getting Started or Los
Geht’s manuals).
• Priority Voice Technology—incoming and outgoing voice calls take
precedence over existing 2-B-channel data connections (e.g. Multi-
LinkPPP).
This means that the data connection temporarily gives up one of its
B channels for the duration of the voice call.
• STAC compression—V!CAS supports the STAC compression ac-
cording to RFC 1974 and 1962 standards (PPP Stac LZS Compres-
sion Protocol and PPP Compression Control Protocol respectively)
which—depending on the data—can increase performance to a
factor of four.
The Stacker LZS algorithm is developed by Hi/fn Inc.
STAC compression on the V!CAS is also compatible with Cisco’s
proprietary STAC implementation which is automatically detected
at connection time.
These are but a few instances. You will find many more in examples
throughout this guide and the other manuals of your user documenta-
tion.
Note
:
Your ISDN access has to support the »Call waiting« feature
(»Anklopfen« in Germany) for the incoming voice call to be
signalled to your V!CAS.
Without this feature, the Priority Voice Technology only
works for outgoing voice calls.
