 10         select SLHC
 11         help
 12           Over digital connections such as ISDN, there is no need to
 13           synchronize sender and recipient's clocks with start and stop bits
 14           as is done over analog telephone lines. Instead, one can use
 15           "synchronous PPP". Saying Y here will include this protocol. This
 16           protocol is used by Cisco and Sun for example. So you want to say Y
 17           here if the other end of your ISDN connection supports it. You will
 18           need a special version of pppd (called ipppd) for using this
 19           feature. See <file:Documentation/isdn/README.syncppp> and
 20           <file:Documentation/isdn/syncPPP.FAQ> for more information.
 22 config ISDN_PPP_VJ
 23         bool "Use VJ-compression with synchronous PPP"
 24         depends on ISDN_PPP
 25         help
 26           This enables Van Jacobson header compression for synchronous PPP.
 27           Say Y if the other end of the connection supports it.
 29 config ISDN_MPP
 30         bool "Support generic MP (RFC 1717)"
 31         depends on ISDN_PPP
 32         help
 33           With synchronous PPP enabled, it is possible to increase throughput
 34           by bundling several ISDN-connections, using this protocol. See
 35           <file:Documentation/isdn/README.syncppp> for more information.
 37 config IPPP_FILTER
 38         bool "Filtering for synchronous PPP"
 39         depends on ISDN_PPP
 40         help
 41           Say Y here if you want to be able to filter the packets passing over
 42           IPPP interfaces.  This allows you to control which packets count as
 43           activity (i.e. which packets will reset the idle timer or bring up
 44           a demand-dialled link) and which packets are to be dropped entirely.
 45           You need to say Y here if you wish to use the pass-filter and
 46           active-filter options to ipppd.
 49         tristate "Support BSD compression"
 50         depends on ISDN_PPP
 51         help
 52           Support for the BSD-Compress compression method for PPP, which uses
 53           the LZW compression method to compress each PPP packet before it is
 54           sent over the wire. The machine at the other end of the PPP link
 55           (usually your ISP) has to support the BSD-Compress compression
 56           method as well for this to be useful. Even if they don't support it,
 57           it is safe to say Y here.
 59 config ISDN_AUDIO
 60         bool "Support audio via ISDN"
 61         help
 62           If you say Y here, the modem-emulator will support a subset of the
 63           EIA Class 8 Voice commands. Using a getty with voice-support
 64           (mgetty+sendfax by <> with an extension, available
 65           with the ISDN utility package for example), you will be able to use
 66           your Linux box as an ISDN-answering machine. Of course, this must be
 67           supported by the lowlevel driver also. Currently, the HiSax driver
 68           is the only voice-supporting driver. See
 69           <file:Documentation/isdn/> for more information.
 71 config ISDN_TTY_FAX
 72         bool "Support AT-Fax Class 1 and 2 commands"
 73         depends on ISDN_AUDIO
 74         help
 75           If you say Y here, the modem-emulator will support a subset of the
 76           Fax Class 1 and 2 commands. Using a getty with fax-support
 77           (mgetty+sendfax, hylafax), you will be able to use your Linux box as
 78           an ISDN-fax-machine. This must be supported by the lowlevel driver
 79           also. See <file:Documentation/isdn/README.fax> for more information.
 81 config ISDN_X25
 82         bool "X.25 PLP on top of ISDN"
 83         depends on X25
 84         help
 85           This feature provides the X.25 protocol over ISDN connections.
 86           See <file:Documentation/isdn/README.x25> for more information
 87           if you are thinking about using this.

 93         tristate "isdnloop support"
 94         depends on BROKEN_ON_SMP
 95         help
 96           This driver provides a virtual ISDN card. Its primary purpose is
 97           testing of linklevel features or configuration without getting
 98           charged by your service-provider for lots of phone calls.
 99           You need will need the loopctrl utility from the latest isdn4k-utils
100           package to set up this driver.
103         tristate "Support isdn diversion services"
104         help
105           This option allows you to use some supplementary diversion
106           services in conjunction with the HiSax driver on an EURO/DSS1
107           line.
109           Supported options are CD (call deflection), CFU (Call forward
110           unconditional), CFB (Call forward when busy) and CFNR (call forward
111           not reachable). Additionally the actual CFU, CFB and CFNR state may
112           be interrogated.
114           The use of CFU, CFB, CFNR and interrogation may be limited to some
115           countries. The keypad protocol is still not implemented. CD should
116           work in all countries if the service has been subscribed to.
118           Please read the file <file:Documentation/isdn/README.diversion>.
