I tried to find any indication of whether the capi drivers are still in use, and have not found anything from a long time ago. With public ISDN networks almost completely shut down over the past 12 months, there is very little you can actually do with this hardware. The main remaining use case would be to connect ISDN voice phones to an in-house installation with Asterisk or LCR, but anyone trying this in turn seems to be using either the mISDN driver stack, or out-of-tree drivers from the hardware vendors. I may of course have missed something, so I would suggest moving these three drivers (avm, hysdn, gigaset) into drivers/staging/ just in case someone still uses them. If nobody complains, we can remove them entirely in six months, or otherwise move the core code and any drivers that are still needed back into drivers/isdn. As Paul Bolle notes, he is still testing the gigaset driver as long as he can, but the Dutch ISDN network will be shut down in September 2019, which puts an end to that. Marcel Holtmann still maintains the Bluetooth CMTP profile and wants to keep that alive, so the actual CAPI subsystem code remains in place for now, after all other drivers are gone, CMTP and CAPI can be merged into a single driver directory.

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.
