1# 2# Old ISDN4Linux config 3# 4 5if ISDN_I4L 6 7config ISDN_PPP 8 bool "Support synchronous PPP" 9 depends on INET 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. 21 22config 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. 28 29config 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. 36 37config 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. 47 48config ISDN_PPP_BSDCOMP 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. 58 59config 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 <gert@greenie.muc.de> 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/README.audio> for more information. 70 71config 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. 80 81config 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. 88 89 90menu "ISDN feature submodules" 91 92config ISDN_DRV_LOOP 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. 101 102config ISDN_DIVERSION 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. 108 109 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. 113 114 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. 117 118 Please read the file <file:Documentation/isdn/README.diversion>. 119 120endmenu 121 122comment "ISDN4Linux hardware drivers" 123 124source "drivers/isdn/hisax/Kconfig" 125 126# end ISDN_I4L 127endif 128 129
