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.

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>.
