sion for all ISDN connections so that the controller will attempt
to negotiate V.42bis data compression with the remote
site for all X.75 connections, independent of the CAPI
application. If the remote site does not perform data compression,
the data will be transmitted without compression.
This process takes place in the background and is not apparent
to the user.
The “Changing the Settings” sections for each operating
system describes how to enable or disable V.42 data compression
after installation. For Novell NetWare, this information
is contained in the sections “Configuring the ISDN-Controller
B1 PCI v4.0 with Stand-Alone CAPI” on page 43 and
“ISDN-Controller B1 PCI v4.0 with CAPI for the CAPI Manager”
on page 45.
If your computer does not meet the hardware requirements
or if unexpected problems arise during data exchange with
remote sites without V.42 capability, it is advisable to disable
data compression in both the driver and the application.
If you have problems establishing a connection, try disabling
data compression.
The CAPI SoftFax feature allows the ISDN-Controller to send
and receive faces on two B channels simultaneously at up to
14.4 kBit/s. The ISDN-Controller sends and receives like a
G3 fax device.
The following fax protocols are supported:
� V.17 (14.4 kBit/s)
� V.29 (9.6 kBit/s)
� ECM (Error Correction Mode)
� MR/MMR (2D compression)
