|
|
<P> To use ISDN you must have a special ISDN telephone line supplied
|
|
by your telephone company at additional cost. An ISDN "modem" is
|
|
really a Terminal Adapter (TA). Like analog modems, there are
|
|
internal ones on cards and external ones that connect to serial ports.</P>

|
|
|
|
<P>Configuring an external ISDN modem on a serial port is about the
|
|
same as configuring an analog modem. The main difference is in the
|
|
init string. Unfortunately, the init strings are different for
|
|
different models of ISDN modems. There is often one AT command for a
|
|
speed of 64k and another for 128k, etc. So you need to find out what
|
|
init string to use and tell it to say wvdial, etc.</P>

|
|
|
|
<P>Support for some of these cards can be built into the 2.4 or 2.6
|
|
kernels or added as a module. The tty ports are ttyI2 for example.
|
|
The kernel documentation has an "isdn" subdirectory which describes
|
|
various drivers which support various isdn cards. A major website for
|
|
ISDN is

|
|
<P>For configuring, one might use the "isdn-config" GUI. A Debian
|
|
package "isdnutils" is available. There is SuSE ISDN Howto (not a LDP
|
|
Howto) which is translated from German
|
|
<A HREF="http://sol.parkland.cc.il.us/sdb/en/html/isdn.html">http://sol.parkland.cc.il.us/sdb/en/html/isdn.html</A> There is an
|
|
isdn4linux package and a newsgroup: de.alt.comm.isdn4linux. Many of
|
|
the postings are in German. </P>
