-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.

-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>.
