Before it went into kernel, the package - had a unique version number. The last version, distributed separately - was 0.7.4. When the subsystem went into kernel, every functional unit - got a separate version number.

Those programs and some contributed utilities are available - at - - ftp.isdn4linux.de - - /pub/isdn4linux/isdn4k-utils-<VersionNumber>.tar.gz - - - We also have set up a mailing-list: - - The isdn4linux-project originates in Germany, and therefore by historical - reasons, the mailing-list's primary language is german. However mails - written in english have been welcome all the time. - - to subscribe: write a email to majordomo@listserv.isdn4linux.de, - Subject irrelevant, in the message body: - subscribe isdn4linux <your_email_address> - - To write to the mailing-list, write to isdn4linux@listserv.isdn4linux.de - - This mailinglist is bidirectionally gated to the newsgroup - - de.alt.comm.isdn4linux - - There is also a well maintained FAQ in English available at - https://www.mhessler.de/i4lfaq/ - It can be viewed online, or downloaded in sgml/text/html format. - The FAQ can also be viewed online at - https://www.isdn4linux.de/faq/i4lfaq.html - or downloaded from - ftp://ftp.isdn4linux.de/pub/isdn4linux/FAQ/ - - 1.1 Technical details - - In the following Text, the terms MSN and EAZ are used. - - MSN is the abbreviation for (M)ultiple(S)ubscriber(N)umber, and applies - to Euro(EDSS1)-type lines. Usually it is simply the phone number. - - EAZ is the abbreviation of (E)ndgeraete(A)uswahl(Z)iffer and - applies to German 1TR6-type lines. This is a one-digit string, - simply appended to the base phone number - - The internal handling is nearly identical, so replace the appropriate - term to that one, which applies to your local ISDN-environment. - - When the link-level-module isdn.o is loaded, it supports up to 16 - low-level-modules with up to 64 channels. (The number 64 is arbitrarily - chosen and can be configured at compile-time --ISDN_MAX in isdn.h). - A low-level-driver can register itself through an interface (which is - defined in isdnif.h) and gets assigned a slot. - The following char-devices are made available for each channel: - - A raw-control-device with the following functions: - write: raw D-channel-messages (format: depends on driver). - read: raw D-channel-messages (format: depends on driver). - ioctl: depends on driver, i.e. for the ICN-driver, the base-address of - the ports and the shared memory on the card can be set and read - also the boot-code and the protocol software can be loaded into - the card. - - O N L Y !!! for debugging (no locking against other devices): - One raw-data-device with the following functions: - write: data to B-channel. - read: data from B-channel. - - In addition the following devices are made available: - - 128 tty-devices (64 cuix and 64 ttyIx) with integrated modem-emulator: - The functionality is almost the same as that of a serial device - (the line-discs are handled by the kernel), which lets you run - SLIP, CSLIP and asynchronous PPP through the devices. We have tested - Seyon, minicom, CSLIP (uri-dip) PPP, mgetty, XCept and Hylafax. - - The modem-emulation supports the following: - 1.3.1 Commands: - - ATA Answer incoming call. - ATD<No.> Dial, the number may contain: - [0-9] and [,#.*WPT-S] - the latter are ignored until 'S'. - The 'S' must precede the number, if - the line is a SPV (German 1TR6). - ATE0 Echo off. - ATE1 Echo on (default). - ATH Hang-up. - ATH1 Off hook (ignored). - ATH0 Hang-up. - ATI Return "ISDN for Linux...". - ATI0 " - ATI1 " - ATI2 Report of last connection. - ATO On line (data mode). - ATQ0 Enable result codes (default). - ATQ1 Disable result codes (default). - ATSx=y Set register x to y. - ATSx?

You will get NO Error-Message, - if you set it to higher values, because at the - time of giving this command the corresponding - driver may not be selected (see "Automatic - Assignment") however the size of outgoing packets - will be limited correctly. - AT&D0 Ignore DTR - AT&D2 DTR-low-edge: Hang up and return to - command mode (default). - AT&D3 Same as AT&D2 but also resets all registers. - AT&Ex Set the EAZ/MSN for this channel to x. - AT&F Reset all registers and profile to "factory-defaults" - AT&Lx Set list of phone numbers to listen on. x is a - list of wildcard patterns separated by semicolon. - If this is set, it has precedence over the MSN set - by AT&E. - AT&Rx Select V.110 bitrate adaption. - This command enables V.110 protocol with 9600 baud - (x=9600), 19200 baud (x=19200) or 38400 baud - (x=38400). A value of x=0 disables V.110 switching - back to default X.75.

(only for network interfaces if the security flag is set) - contains the caller number in its access list. - 4. Either the channel is not bound exclusively to another Net-interface, or - it is bound AND the other checks apply to exactly this interface. - (For usage of the bind-features, refer to the isdnctrl-man-page) - - Only when a matching interface or tty is found is the call accepted - and the "connection" between the low-level-layer and the link-level-layer - is established and kept until the end of the connection. - In all other cases no connection is established. Isdn4linux can be - configured to either do NOTHING in this case (which is useful, if - other, external devices with the same EAZ/MSN are connected to the bus) - or to reject the call actively. (isdnctrl busreject ...) - - For an outgoing call, the inactive physical lines are searched. - The call is placed on the first physical line, which supports the - requested protocols for the B-channel. If a net-interface, however - is pre-bound to a channel, this channel is used directly. - - This makes it possible to configure several network interfaces and ttys - for one EAZ, if the network interfaces are set to secure operation. - If an incoming call matches one network interface, it gets connected to it. - If another incoming call for the same EAZ arrives, which does not match - a network interface, the first tty gets a "RING" and so on. - -2 System prerequisites: - - ATTENTION! - - Always use the latest module utilities. The current version is - named in Documentation/Changes. Some old versions of insmod - are not capable of setting the driver-Ids correctly. - -3. Lowlevel-driver configuration. - - Configuration depends on how the drivers are built. See the - README.<yourDriver> for information on driver-specific setup. - -4. Device-inodes - - The major and minor numbers and their names are described in - Documentation/admin-guide/devices.rst. The major numbers are: - - 43 for the ISDN-tty's. - 44 for the ISDN-callout-tty's. - 45 for control/info/debug devices. - -5. Application - - a) For some card-types, firmware has to be loaded into the cards, before - proceeding with device-independent setup. See README.<yourDriver> - for how to do that. - - b) If you only intend to use ttys, you are nearly ready now. - - c) If you want to have really permanent "Modem"-settings on disk, you - can start the daemon iprofd. Give it a path to a file at the command- - line. It will store the profile-settings in this file every time - an AT&W0 is performed on any ISDN-tty. If the file already exists, - all profiles are initialized from this file. If you want to unload - any of the modules, kill iprofd first. - - d) For networking, continue: Create an interface: - isdnctrl addif isdn0 - - e) Set the EAZ (or MSN for Euro-ISDN): - isdnctrl eaz isdn0 2 - - (For 1TR6 a single digit is allowed, for Euro-ISDN the number is your - real MSN e.g.: Phone-Number) - - f) Set the number for outgoing calls on the interface: - isdnctrl addphone isdn0 out 1234567 - ... (this can be executed more than once, all assigned numbers are - tried in order) - and the number(s) for incoming calls: - isdnctrl addphone isdn0 in 1234567 - - g) Set the timeout for hang-up: - isdnctrl huptimeout isdn0 <timeout_in_seconds> - - h) additionally you may activate charge-hang-up (= Hang up before - next charge-info, this only works, if your isdn-provider transmits - the charge-info during and after the connection): - isdnctrl chargehup isdn0 on - - i) Set the dial mode of the interface: - isdnctrl dialmode isdn0 auto - "off" means that you (or the system) cannot make any connection - (neither incoming or outgoing connections are possible). Use - this if you want to be sure that no connections will be made. - "auto" means that the interface is in auto-dial mode, and will - attempt to make a connection whenever a network data packet needs - the interface's link. Note that this can cause unexpected dialouts, - and lead to a high phone bill! Some daemons or other pc's that use - this interface can cause this. - Incoming connections are also possible. - "manual" is a dial mode created to prevent the unexpected dialouts. - In this mode, the interface will never make any connections on its - own. You must explicitly initiate a connection with "isdnctrl dial - isdn0". However, after an idle time of no traffic as configured for - the huptimeout value with isdnctrl, the connection _will_ be ended. - If you don't want any automatic hangup, set the huptimeout value to 0. - "manual" is the default. - - j) Setup the interface with ifconfig as usual, and set a route to it. - - k) (optional) If you run X11 and have Tcl/Tk-wish version 4.0, you can use - the script tools/tcltk/isdnmon. You can add actions for line-status - changes. See the comments at the beginning of the script for how to - do that. There are other tty-based tools in the tools-subdirectory - contributed by Michael Knigge (imon), Volker Götz (imontty) and - Andreas Kool (isdnmon). - - l) For initial testing, you can set the verbose-level to 2 (default: 0). - Then all incoming calls are logged, even if they are not addressed - to one of the configured net-interfaces: - isdnctrl verbose 2 - - Now you are ready! A ping to the set address should now result in an - automatic dial-out (look at syslog kernel-messages). - The phone numbers and EAZs can be assigned at any time with isdnctrl. - You can add as many interfaces as you like with addif following the - directions above. Of course, there may be some limitations. But we have - tested as many as 20 interfaces without any problem. However, if you - don't give an interface name to addif, the kernel will assign a name - which starts with "eth". The number of "eth"-interfaces is limited by - the kernel. - -5. Additional options for isdnctrl: - - "isdnctrl secure <InterfaceName> on" - Only incoming calls, for which the caller-id is listed in the access - list of the interface are accepted. You can add caller-id's With the - command "isdnctrl addphone <InterfaceName> in <caller-id>" - Euro-ISDN does not transmit the leading '0' of the caller-id for an - incoming call, therefore you should configure it accordingly. - If the real number for the dialout e.g. is "09311234567" the number - to configure here is "9311234567". The pattern-match function - works similar to the shell mechanism. - - ? one arbitrary digit - * zero or arbitrary many digits - [123] one of the digits in the list - [1-5] one digit between '1' and '5' - a '^' as the first character in a list inverts the list - - - "isdnctrl secure <InterfaceName> off" - Switch off secure operation (default). - - "isdnctrl ihup <InterfaceName> [on|off]" - Switch the hang-up-timer for incoming calls on or off. - - "isdnctrl eaz <InterfaceName>" - Returns the EAZ of an interface. - - "isdnctrl delphone <InterfaceName> in|out <number>" - Deletes a number from one of the access-lists of the interface. - - "isdnctrl delif <InterfaceName>" - Removes the interface (and possible slaves) from the kernel. - (You have to unregister it with "ifconfig <InterfaceName> down" before). - - "isdnctrl callback <InterfaceName> [on|off]" - Switches an interface to callback-mode. In this mode, an incoming call - will be rejected and after this the remote-station will be called. If - you test this feature by using ping, some routers will re-dial very - quickly, so that the callback from isdn4linux may not be recognized. - In this case use ping with the option -i <sec> to increase the interval - between echo-packets. - - "isdnctrl cbdelay <InterfaceName> [seconds]" - Sets the delay (default 5 sec) between an incoming call and start of - dialing when callback is enabled. - - "isdnctrl cbhup <InterfaceName> [on|off]" - This enables (default) or disables an active hangup (reject) when getting an - incoming call for an interface which is configured for callback. - - "isdnctrl encap <InterfaceName> <EncapType>" - Selects the type of packet-encapsulation. The encapsulation can be changed - only while an interface is down. - - At the moment the following values are supported: - - rawip (Default) Selects raw-IP-encapsulation. This means, MAC-headers - are stripped off. - ip IP with type-field. Same as IP but the type-field of the MAC-header - is preserved. - x25iface X.25 interface encapsulation (first byte semantics as defined in - ../networking/x25-iface.txt). Use this for running the linux - X.25 network protocol stack (AF_X25 sockets) on top of isdn. - cisco-h A special-mode for communicating with a Cisco, which is configured - to do "hdlc" - ethernet No stripping.

This can be done with the above - command. Replace <DriverId> by whatever you assigned while loading the - module. The <ChannelNumber> is counted from zero. The upper limit - depends on the card used. At the moment no card supports more than - 2 channels, so the upper limit is one. - - "isdnctrl unbind <InterfaceName>" - unbinds a previously bound interface. - - "isdnctrl busreject <DriverId> on|off" - If switched on, isdn4linux replies a REJECT to incoming calls, it - cannot match to any configured interface. - If switched off, nothing happens in this case. - You normally should NOT enable this feature, if the ISDN adapter is not - the only device connected to the S0-bus. Otherwise it could happen that - isdn4linux rejects an incoming call, which belongs to another device on - the bus. - - "isdnctrl addslave <InterfaceName> <SlaveName> - Creates a slave interface for channel-bundling. Slave interfaces are - not seen by the kernel, but their ISDN-part can be configured with - isdnctrl as usual. (Phone numbers, EAZ/MSN, timeouts etc.) If more - than two channels are to be bundled, feel free to create as many as you - want. InterfaceName must be a real interface, NOT a slave. Slave interfaces - start dialing, if the master interface resp. the previous slave interface - has a load of more than 7000 cps. They hangup if the load goes under 7000 - cps, according to their "huptimeout"-parameter. - - "isdnctrl sdelay <InterfaceName> secs." - This sets the minimum time an Interface has to be fully loaded, until - it sends a dial-request to its slave. - - "isdnctrl dial <InterfaceName>" - Forces an interface to start dialing even if no packets are to be - transferred. - - "isdnctrl mapping <DriverId> MSN0,MSN1,MSN2,...MSN9" - This installs a mapping table for EAZ<->MSN-mapping for a single line. - Missing MSN's have to be given as "-" or can be omitted, if at the end - of the commandline. - With this command, it's now possible to have an interface listening to - mixed 1TR6- and Euro-Type lines. In this case, the interface has to be - configured to a 1TR6-type EAZ (one digit). The mapping is also valid - for tty-emulation. Seen from the interface/tty-level the mapping - CAN be used, however it's possible to use single tty's/interfaces with - real MSN's (more digits) also, in which case the mapping will be ignored. - Here is an example: - - You have a 1TR6-type line with base-nr. 1234567 and a Euro-line with - MSN's 987654, 987655 and 987656.

Incoming calls may be diverted - unconditionally (CFU), when not reachable (CFNR) or on busy condition - (CFB). - The diversions may be invoked statically in the providers exchange - as normally done by isdn phones. In this case all incoming calls - with a special (or all) service identifiers are forwarded if the - forwarding reason is met. Activated static services may also be - interrogated (queried). - The i4l diversion services additionally offers a dynamic version of - call forwarding which is not preprogrammed inside the providers exchange - but dynamically activated by i4l. - In this case all incoming calls are checked by rules that may be - compared to the mechanism of ipfwadm or ipchains. If a given rule matches - the checking process is finished and the rule matching will be applied - to the call. - The rules include primary and secondary service identifiers, called - number and subaddress, callers number and subaddress and whether the rule - matches to all filtered calls or only those when all B-channel resources - are exhausted. - Actions that may be invoked by a rule are ignore, proceed, reject, - direct divert or delayed divert of a call. - All incoming calls matching a rule except the ignore rule a reported and - logged as ASCII via the proc filesystem (/proc/net/isdn/divert). If proceed - is selected the call will be held in a proceeding state (without ringing) - for a certain amount of time to let an external program or client decide - how to handle the call. - - -2. Required hard- and software - - For using the i4l diversion services the isdn line must be of a EURO/DSS1 - type. Additionally the i4l services only work together with the HiSax - driver for passive isdn cards. All HiSax supported cards may be used for - the diversion purposes. - The static diversion services require the provider having static services - CFU, CFNR, CFB activated on an MSN-line. The static services may not be - used on a point-to-point connection. Further the static services are only - available in some countries (for example germany). Countries requiring the - keypad protocol for activating static diversions (like the netherlands) are - not supported but may use the tty devices for this purpose. - The dynamic diversion services may be used in all countries if the provider - enables the feature CF (call forwarding). This should work on both MSN- and - point-to-point lines. - To add and delete rules the additional divertctrl program is needed. This - program is part of the isdn4kutils package. - -3. Compiling, installing and loading/unloading the module - Tracing calling and diversion information - - - To compile the i4l code with diversion support you need to say yes to the - DSS1 diversion services when selecting the i4l options in the kernel - config (menuconfig or config). - After having properly activated a make modules and make modules_install all - required modules will be correctly installed in the needed modules dirs. - As the diversion services are currently not included in the scripts of most - standard distributions you will have to add a "insmod dss1_divert" after - having loaded the global isdn module. - The module can be loaded without any command line parameters. - If the module is actually loaded and active may be checked with a - "cat /proc/modules" or "ls /proc/net/isdn/divert".
