Functions of the Driver Software
ISDN is equipped with three channels: two B channels and one
D channel. The B channels are used for data transmission such
as faxes. The ISDN terminal device, such as the ISDN-Controller
FRITZ!Card, uses the D channel to communicate with the digital
exchange: among the information transferred via this channel
are connection charges. The CAPI 2.0 driver software processes
the D-channel protocol of the ISDN connection and puts all
required B-channel protocols (X.75, HDLC, etc.) at the disposal
of the applications. CAPI 2.0 also provides SoftCompression
X75/V42bis, SoftModem and SoftFax G3.
CAPI SoftCompression X75/V42bis
The driver software for the ISDN-Controller FRITZ!Card supports
data compression as per V.42bis for X.75 connections in
accordance with the CAPI standard. Connection times and costs
can be reduced considerably with this type of data compression.
