With all isdn4linux hardware drivers gone, this is only a wrapper around CAPI to support old user space. However, from looking at the mailing list, it seems that the last time anyone asked about it was in 2014, when the upgrade from a linux-2.4 installation failed, and mISDN was suggested as a replacement. The largest public ISDN network (Deutsche Telekom) was supposed to be shut down 2018, which must have drastically reduced the number of legacy installations. When we last discussed removing i4l in 2016, Karsten Keil suggested revisiting this in 2018. I guess this is overdue.

ISDN ("Integrated Services Digital Network", called RNIS in France)
|
|
is a fully digital telephone service that can be used for voice and
|
|
data connections. If your computer is equipped with an ISDN
|
|
adapter you can use it to connect to your Internet service provider
|
|
(with SLIP or PPP) faster than via a conventional telephone modem
|
|
(though still much slower than with DSL) or to make and accept
|
|
voice calls (eg. turning your PC into a software answering machine
|
|
or PABX).
|
|
|
|
Select this option if you want your kernel to support ISDN.

This provides CAPI (the Common ISDN Application Programming
|
|
Interface) Version 2.0, a standard making it easy for programs to
|
|
access ISDN hardware in a device independent way. (For details see
|
|
<http://www.capi.org/>.) CAPI supports making and accepting voice
|
|
and data connections, controlling call options and protocols,
|
|
as well as ISDN supplementary services like call forwarding or
|
|
three-party conferences (if supported by the specific hardware
|
|
driver).
|
|
|
|
Select this option and the appropriate hardware driver below if
|
|
you have an ISDN adapter supported by the CAPI subsystem.
