2 # Old ISDN4Linux config
6 bool "Support synchronous PPP"
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.
21 bool "Use VJ-compression with synchronous PPP"
24 This enables Van Jacobson header compression for synchronous PPP.
25 Say Y if the other end of the connection supports it.
28 bool "Support generic MP (RFC 1717)"
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.
36 bool "Filtering for synchronous PPP"
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.
46 config ISDN_PPP_BSDCOMP
47 tristate "Support BSD compression"
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.
58 bool "Support audio via ISDN"
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.
70 bool "Support AT-Fax Class 1 and 2 commands"
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.
80 bool "X.25 PLP on top of ISDN"
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.
88 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"
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>.
