2 # Old ISDN4Linux config
6 bool "Support synchronous PPP"
9 Over digital connections such as ISDN, there is no need to
10 synchronize sender and recipient's clocks with start and stop bits
11 as is done over analog telephone lines. Instead, one can use
12 "synchronous PPP". Saying Y here will include this protocol. This
13 protocol is used by Cisco and Sun for example. So you want to say Y
14 here if the other end of your ISDN connection supports it. You will
15 need a special version of pppd (called ipppd) for using this
16 feature. See <file:Documentation/isdn/README.syncppp> and
17 <file:Documentation/isdn/syncPPP.FAQ> for more information.
20 bool "Use VJ-compression with synchronous PPP"
23 This enables Van Jacobson header compression for synchronous PPP.
24 Say Y if the other end of the connection supports it.
27 bool "Support generic MP (RFC 1717)"
30 With synchronous PPP enabled, it is possible to increase throughput
31 by bundling several ISDN-connections, using this protocol. See
32 <file:Documentation/isdn/README.syncppp> for more information.
35 bool "Filtering for synchronous PPP"
38 Say Y here if you want to be able to filter the packets passing over
39 IPPP interfaces. This allows you to control which packets count as
40 activity (i.e. which packets will reset the idle timer or bring up
41 a demand-dialled link) and which packets are to be dropped entirely.
42 You need to say Y here if you wish to use the pass-filter and
43 active-filter options to ipppd.
45 config ISDN_PPP_BSDCOMP
46 tristate "Support BSD compression"
49 Support for the BSD-Compress compression method for PPP, which uses
50 the LZW compression method to compress each PPP packet before it is
51 sent over the wire. The machine at the other end of the PPP link
52 (usually your ISP) has to support the BSD-Compress compression
53 method as well for this to be useful. Even if they don't support it,
54 it is safe to say Y here.
57 bool "Support audio via ISDN"
59 If you say Y here, the modem-emulator will support a subset of the
60 EIA Class 8 Voice commands. Using a getty with voice-support
61 (mgetty+sendfax by <gert@greenie.muc.de> with an extension, available
62 with the ISDN utility package for example), you will be able to use
63 your Linux box as an ISDN-answering machine. Of course, this must be
64 supported by the lowlevel driver also. Currently, the HiSax driver
65 is the only voice-supporting driver. See
66 <file:Documentation/isdn/README.audio> for more information.
69 bool "Support AT-Fax Class 1 and 2 commands"
72 If you say Y here, the modem-emulator will support a subset of the
73 Fax Class 1 and 2 commands. Using a getty with fax-support
74 (mgetty+sendfax, hylafax), you will be able to use your Linux box as
75 an ISDN-fax-machine. This must be supported by the lowlevel driver
76 also. See <file:Documentation/isdn/README.fax> for more information.
79 bool "X.25 PLP on top of ISDN"
82 This feature provides the X.25 protocol over ISDN connections.
83 See <file:Documentation/isdn/README.x25> for more information
84 if you are thinking about using this.
87 menu "ISDN feature submodules"
91 tristate "isdnloop support"
92 depends on BROKEN_ON_SMP
94 This driver provides a virtual ISDN card. Its primary purpose is
95 testing of linklevel features or configuration without getting
96 charged by your service-provider for lots of phone calls.
97 You need will need the loopctrl utility from the latest isdn4k-utils
98 package to set up this driver.
100 config ISDN_DIVERSION
101 tristate "Support isdn diversion services"
102 depends on ISDN && ISDN_I4L
104 This option allows you to use some supplementary diversion
105 services in conjunction with the HiSax driver on an EURO/DSS1
108 Supported options are CD (call deflection), CFU (Call forward
109 unconditional), CFB (Call forward when busy) and CFNR (call forward
110 not reachable). Additionally the actual CFU, CFB and CFNR state may
113 The use of CFU, CFB, CFNR and interrogation may be limited to some
114 countries. The keypad protocol is still not implemented. CD should
115 work in all countries if the service has been subscribed to.
117 Please read the file <file:Documentation/isdn/README.diversion>.
