|  | 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. |

|  | 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>. |
