1# 2# Old ISDN4Linux config 3# 4 5config ISDN_PPP 6 bool "Support synchronous PPP" 7 depends on INET 8 select SLHC 9 help 10 Over digital connections such as ISDN, there is no need to 11 synchronize sender and recipient's clocks with start and stop bits 12 as is done over analog telephone lines. Instead, one can use 13 "synchronous PPP". Saying Y here will include this protocol. This 14 protocol is used by Cisco and Sun for example. So you want to say Y 15 here if the other end of your ISDN connection supports it. You will 16 need a special version of pppd (called ipppd) for using this 17 feature. See <file:Documentation/isdn/README.syncppp> and 18 <file:Documentation/isdn/syncPPP.FAQ> for more information. 19 20config ISDN_PPP_VJ 21 bool "Use VJ-compression with synchronous PPP" 22 depends on ISDN_PPP 23 help 24 This enables Van Jacobson header compression for synchronous PPP. 25 Say Y if the other end of the connection supports it. 26 27config ISDN_MPP 28 bool "Support generic MP (RFC 1717)" 29 depends on ISDN_PPP 30 help 31 With synchronous PPP enabled, it is possible to increase throughput 32 by bundling several ISDN-connections, using this protocol. See 33 <file:Documentation/isdn/README.syncppp> for more information. 34 35config IPPP_FILTER 36 bool "Filtering for synchronous PPP" 37 depends on ISDN_PPP 38 help 39 Say Y here if you want to be able to filter the packets passing over 40 IPPP interfaces. This allows you to control which packets count as 41 activity (i.e. which packets will reset the idle timer or bring up 42 a demand-dialled link) and which packets are to be dropped entirely. 43 You need to say Y here if you wish to use the pass-filter and 44 active-filter options to ipppd. 45 46config ISDN_PPP_BSDCOMP 47 tristate "Support BSD compression" 48 depends on ISDN_PPP 49 help 50 Support for the BSD-Compress compression method for PPP, which uses 51 the LZW compression method to compress each PPP packet before it is 52 sent over the wire. The machine at the other end of the PPP link 53 (usually your ISP) has to support the BSD-Compress compression 54 method as well for this to be useful. Even if they don't support it, 55 it is safe to say Y here. 56 57config ISDN_AUDIO 58 bool "Support audio via ISDN" 59 help 60 If you say Y here, the modem-emulator will support a subset of the 61 EIA Class 8 Voice commands. Using a getty with voice-support 62 (mgetty+sendfax by <gert@greenie.muc.de> with an extension, available 63 with the ISDN utility package for example), you will be able to use 64 your Linux box as an ISDN-answering machine. Of course, this must be 65 supported by the lowlevel driver also. Currently, the HiSax driver 66 is the only voice-supporting driver. See 67 <file:Documentation/isdn/README.audio> for more information. 68 69config ISDN_TTY_FAX 70 bool "Support AT-Fax Class 1 and 2 commands" 71 depends on ISDN_AUDIO 72 help 73 If you say Y here, the modem-emulator will support a subset of the 74 Fax Class 1 and 2 commands. Using a getty with fax-support 75 (mgetty+sendfax, hylafax), you will be able to use your Linux box as 76 an ISDN-fax-machine. This must be supported by the lowlevel driver 77 also. See <file:Documentation/isdn/README.fax> for more information. 78 79config ISDN_X25 80 bool "X.25 PLP on top of ISDN" 81 depends on X25 82 help 83 This feature provides the X.25 protocol over ISDN connections. 84 See <file:Documentation/isdn/README.x25> for more information 85 if you are thinking about using this. 86 87 88menu "ISDN feature submodules" 89 depends on ISDN 90 91config ISDN_DRV_LOOP 92 tristate "isdnloop support" 93 depends on BROKEN_ON_SMP 94 help 95 This driver provides a virtual ISDN card. Its primary purpose is 96 testing of linklevel features or configuration without getting 97 charged by your service-provider for lots of phone calls. 98 You need will need the loopctrl utility from the latest isdn4k-utils 99 package to set up this driver. 100 101config ISDN_DIVERSION 102 tristate "Support isdn diversion services" 103 depends on ISDN && ISDN_I4L 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 depends on NET && ISDN && ISDN_I4L 124 125source "drivers/isdn/hisax/Kconfig" 126 127 128menu "Active cards" 129 depends on NET && ISDN && ISDN_I4L!=n 130 131source "drivers/isdn/icn/Kconfig" 132 133source "drivers/isdn/pcbit/Kconfig" 134 135source "drivers/isdn/sc/Kconfig" 136 137source "drivers/isdn/act2000/Kconfig" 138 139source "drivers/isdn/hysdn/Kconfig" 140 141endmenu 142 143source "drivers/isdn/gigaset/Kconfig" 144
