# Old ISDN4Linux config

config ISDN_PPP
bool "Support synchronous PPP"
depends on INET
select SLHC
help
Over digital connections such as ISDN, there is no need to
synchronize sender and recipient's clocks with start and stop bits
as is done over analog telephone lines. Instead, one can use
"synchronous PPP". Saying Y here will include this protocol. This
protocol is used by Cisco and Sun for example. So you want to say Y
here if the other end of your ISDN connection supports it. You will
need a special version of pppd (called ipppd) for using this
feature. See <file:Documentation/isdn/README.syncppp> and
<file:Documentation/isdn/syncPPP.FAQ> for more information.
config ISDN_PPP_VJ
bool "Use VJ-compression with synchronous PPP"
depends on ISDN_PPP
help
This enables Van Jacobson header compression for synchronous PPP.
Say Y if the other end of the connection supports it.
config ISDN_MPP
bool "Support generic MP (RFC 1717)"
depends on ISDN_PPP
help
With synchronous PPP enabled, it is possible to increase throughput
by bundling several ISDN-connections, using this protocol. See
<file:Documentation/isdn/README.syncppp> for more information.
config IPPP_FILTER
bool "Filtering for synchronous PPP"
depends on ISDN_PPP
help
Say Y here if you want to be able to filter the packets passing over
IPPP interfaces. This allows you to control which packets count as
activity (i.e. which packets will reset the idle timer or bring up
a demand-dialled link) and which packets are to be dropped entirely.
You need to say Y here if you wish to use the pass-filter and
active-filter options to ipppd.
config ISDN_PPP_BSDCOMP
tristate "Support BSD compression"
depends on ISDN_PPP
help
Support for the BSD-Compress compression method for PPP, which uses
the LZW compression method to compress each PPP packet before it is
sent over the wire. The machine at the other end of the PPP link
(usually your ISP) has to support the BSD-Compress compression
method as well for this to be useful. Even if they don't support it,
it is safe to say Y here.
config ISDN_AUDIO
bool "Support audio via ISDN"
help
If you say Y here, the modem-emulator will support a subset of the
EIA Class 8 Voice commands. Using a getty with voice-support
(mgetty+sendfax by <gert@greenie.muc.de> with an extension, available
with the ISDN utility package for example), you will be able to use
your Linux box as an ISDN-answering machine. Of course, this must be
supported by the lowlevel driver also. Currently, the HiSax driver
is the only voice-supporting driver. See
<file:Documentation/isdn/README.audio> for more information.
config ISDN_TTY_FAX
bool "Support AT-Fax Class 1 and 2 commands"
depends on ISDN_AUDIO
help
If you say Y here, the modem-emulator will support a subset of the
Fax Class 1 and 2 commands. Using a getty with fax-support
(mgetty+sendfax, hylafax), you will be able to use your Linux box as
an ISDN-fax-machine. This must be supported by the lowlevel driver
also. See <file:Documentation/isdn/README.fax> for more information.
config ISDN_X25
bool "X.25 PLP on top of ISDN"
depends on X25
help
This feature provides the X.25 protocol over ISDN connections.
See <file:Documentation/isdn/README.x25> for more information
if you are thinking about using this.
menu "ISDN feature submodules"
config ISDN_DRV_LOOP
tristate "isdnloop support"
depends on BROKEN_ON_SMP
help
This driver provides a virtual ISDN card. Its primary purpose is
testing of linklevel features or configuration without getting
charged by your service-provider for lots of phone calls.
You need will need the loopctrl utility from the latest isdn4k-utils
package to set up this driver.
config ISDN_DIVERSION
tristate "Support isdn diversion services"
help
This option allows you to use some supplementary diversion
services in conjunction with the HiSax driver on an EURO/DSS1
line.
Supported options are CD (call deflection), CFU (Call forward
unconditional), CFB (Call forward when busy) and CFNR (call forward
not reachable). Additionally the actual CFU, CFB and CFNR state may
be interrogated.
The use of CFU, CFB, CFNR and interrogation may be limited to some
countries. The keypad protocol is still not implemented. CD should
work in all countries if the service has been subscribed to.
Please read the file <file:Documentation/isdn/README.diversion>.
