8 bool "Support synchronous PPP"

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.

26 This enables Van Jacobson header compression for synchronous PPP.
27 Say Y if the other end of the connection supports it.

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.

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.

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.

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.

71config ISDN_TTY_FAX

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.

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.

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.

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>.
