====================
isdn: deprecate non-mISDN drivers
When isdn4linux came up in the context of another patch series, I
remembered that we had discussed removing it a while ago.
It turns out that the suggestion from Karsten Keil wa to remove I4L
in 2018 after the last public ISDN networks are shut down. This has
happened now (with a very small number of exceptions), so I guess it's
time to try again.
We currently have three ISDN stacks in the kernel: the original
isdn4linux (with the hisax driver), the newer CAPI (with four drivers),
and finally the mISDN stack (supporting roughly the same hardware as
hisax).
As far as I can tell, anyone using ISDN with mainline kernel drivers in
the past few years uses mISDN, and this is typically used for voice-only
PBX installations that don't require a public network.
The older stacks support additional features for data networks, but those
typically make no sense any more if there is no network to connect to.
My proposal for this time is to kill off isdn4linux entirely, as it seems
to have been unusable for quite a while. This code has been abandoned
for many years and it does cause problems for treewide maintenance as
it tends to do everything that we try to stop doing.
Birger Harzenetter mentioned that is is still using i4l in order to
make use of the 'divert' feature that is not part of mISDN, but has
otherwise moved on to mISDN for normal operation, like apparently
everyone else.
CAPI in turn is not quite as obsolete, but two of the drivers (avm
and hysdn) don't seem to be used at all, while another one (gigaset)
will stop being maintained as Paul Bolle is no longer able to
test it after the network gets shut down in September.
All three are now moved into drivers/staging to let others speak
up in case there are remaining users.
This leaves Bluetooth CMTP as the only remaining user of CAPI, but
Marcel Holtmann wishes to keep maintaining it.
For the discussion on version 1, see [2]
Unfortunately, Karsten Keil as the maintainer has not participated in
the discussion.

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.

(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. Packets are sent with full MAC-header. - The Ethernet-address of the interface is faked, from its - IP-address: fc:fc:i1:i2:i3:i4, where i1-4 are the IP-addr.-values. - syncppp Synchronous PPP - - uihdlc HDLC with UI-frame-header (for use with DOS ISPA, option -h1) - - - NOTE: x25iface encapsulation is currently experimental. Please - read README.x25 for further details - - - Watching packets, using standard-tcpdump will fail for all encapsulations - except ethernet because tcpdump does not know how to handle packets - without MAC-header. A patch for tcpdump is included in the utility-package - mentioned above. - - "isdnctrl l2_prot <InterfaceName> <L2-ProtocolName>" - Selects a layer-2-protocol. - (With the ICN-driver and the HiSax-driver, "x75i" and "hdlc" is available. - With other drivers, "x75ui", "x75bui", "x25dte", "x25dce" may be - possible too. See README.x25 for x25 related l2 protocols.) - - isdnctrl l3_prot <InterfaceName> <L3-ProtocolName> - The same for layer-3. (At the moment only "trans" is allowed) - - "isdnctrl list <InterfaceName>" - Shows all parameters of an interface and the charge-info. - Try "all" as the interface name. - - "isdnctrl hangup <InterfaceName>" - Forces hangup of an interface. - - "isdnctrl bind <InterfaceName> <DriverId>,<ChannelNumber> [exclusive]" - If you are using more than one ISDN card, it is sometimes necessary to - dial out using a specific card or even preserve a specific channel for - dialout of a specific net-interface. 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. The DriverId for the Euro-line is "EURO". - - isdnctrl mapping EURO -,987654,987655,987656,-,987655 - ... - isdnctrl eaz isdn0 1 # listen on 12345671(1tr6) and 987654(euro) - ... - isdnctrl eaz isdn1 4 # listen on 12345674(1tr6) only. - ... - isdnctrl eaz isdn2 987654 # listen on 987654(euro) only. - - Same scheme is used with AT&E... at the tty's. - -6. If you want to write a new low-level-driver, you are welcome. - The interface to the link-level-module is described in the file INTERFACE. - If the interface should be expanded for any reason, don't do it - on your own, send me a mail containing the proposed changes and - some reasoning about them. - If other drivers will not be affected, I will include the changes - in the next release. - For developers only, there is a second mailing-list.

They also might need to set up or release -the WAN connection. They also might want to send other data for their -private purpose over the wire, e.g. ppp does a lot of link level -negotiation before the first piece of user data can be transmitted. -Such encapsulation protocols for WAN devices are typically more complex -than encapsulation protocols for lan devices. Thus, network interface -code for typical WAN devices also tends to be more complex. - - -In order to support Linux' x25 PLP implementation on top of -isdn network interfaces I could have introduced yet another branch to -the various case statements inside drivers/isdn/isdn_net.c. -This eventually made isdn_net.c even more complex.

Thus, by identifying an abstract -interface between the network interface code and the encapsulation -protocol, complexity could be reduced and maintainability could be -increased. - - -Likewise, a similar encapsulation protocol will frequently be needed by -several different interfaces of even different hardware type, e.g. the -synchronous ppp implementation used by the isdn driver and the -asynchronous ppp implementation used by the ppp driver have a lot of -similar code in them.

Features of the i4l diversion services - (Or what can the i4l diversion services do for me) - - The i4l diversion services offers call forwarding and logging normally - only supported by isdn phones. 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".

(see isdn4linux doc for more) ... -A: Maybe you have compiled the ipppd with another - kernel source tree than the kernel you currently - run ... - --- - -Q03: when I list the netdevices with ifconfig I see, that - my ISDN interface has a HWaddr and IRQ=0 and Base - address = 0 -A: The device is a fake ethernet device .. ignore IRQ and baseaddr - You need the HWaddr only for ethernet encapsulation. - --- - -Q04: MPPP?? What's that and how can I use it ... - -A: MPPP or MP or MPP (Warning: MP is also an - acronym for 'Multi Processor') stands for - Multi Point to Point and means bundling - of several channels to one logical stream. - To enable MPPP negotiation you must call the - ipppd with the '+mp' option. - You must also configure a slave device for - every additional channel. (see the i4l manual - for more) - To use channel bundling you must first activate - the 'master' or initial call. Now you can add - the slave channels with the command: - isdnctrl addlink <device> - e.g: - isdnctrl addlink ippp0 - This is different from other encapsulations of - isdn4linux! With syncPPP, there is no automatic - activation of slave devices. - --- - -Q05: I tried MPPP but it doesn't work .. the ipppd - writes in the debug log something like: - .. rcvd [0][proto=0x3d] c0 00 00 00 80 fd 01 01 00 0a ... - .. sent [0][LCP ProtRej id=0x2 00 3d c0 00 00 00 80 fd 01 ... - -A: you forgot to compile MPPP/RFC1717 support into the - ISDN Subsystem. Recompile with this option enabled. - --- - -Q06: can I use asynchronous PPP encapsulation - over the network interface of isdn4linux .. - -A: No .. that's not possible .. Use the standard - PPP package over the /dev/ttyI* devices. You - must not use the ipppd for this. - --- - -Q07: A SunISDN machine tries to connect my i4l system, - which doesn't work. - Checking the debug log I just saw garbage like: -!![ ... fill in the line ... ]!! - -A: The Sun tries to talk asynchronous PPP ... i4l - can't understand this ... try to use the ttyI* - devices with the standard PPP/pppd package - -A: (from Alexanter Strauss: ) -!![ ... fill in mail ]!! - --- - -Q08: I wanna talk to remote machines, which need - a different configuration. The only way - I found to do this is to kill the ipppd and - start a new one with another config to connect - to the second machine. - -A: you must bind a network interface explicitly to - an ippp device, where you can connect a (for this - interface) individually configured ipppd. - --- - -Q09: When I start the ipppd I only get error messages - from the i4l driver .. - -A: When starting, the ipppd calls functions which may - trigger a network packet. (e.g gethostbyname()). - Without the ipppd (at this moment, it is not - fully started) we can't handle this network request. - Try to configure hostnames necessary for the ipppd - in your local /etc/hosts file or in a way, that - your system can resolve it without using an - isdn/ippp network-interface. - --- - -Q10: I wanna use dynamic IP address assignment ... How - must I configure the network device. - -A: At least you must have a route which forwards - a packet to the ippp network-interface to trigger - the dial-on-demand. - A default route to the ippp-interface will work. - Now you must choose a dummy IP address for your - interface. - If for some reason you can't set the default - route to the ippp interface, you may take any - address of the subnet from which you expect your - dynamic IP number and set a 'network route' for - this subnet to the ippp interface. - To allow overriding of the dummy address you - must call the ipppd with the 'ipcp-accept-local' option. - -A: You must know, how the ipppd gets the addresses it wanna - configure. If you don't give any option, the ipppd - tries to negotiate the local host address! - With the option 'noipdefault' it requests an address - from the remote machine. With 'useifip' it gets the - addresses from the net interface. Or you set the address - on the option line with the <a.b.c.d:e.f.g.h> option. - Note: the IP address of the remote machine must be configured - locally or the remote machine must send it in an IPCP request. - If your side doesn't know the IP address after negotiation, it - closes the connection! - You must allow overriding of address with the 'ipcp-accept-*' - options, if you have set your own or the remote address - explicitly. - -A: Maybe you try these options .. e.g: - - /sbin/ipppd :$REMOTE noipdefault /dev/ippp0 - - where REMOTE must be the address of the remote machine (the - machine, which gives you your address) - --- - -Q11: I can't connect. How can I check where the problem is. - -A: A good help log is the debug output from the ipppd... - Check whether you can find there: - - only a few LCP-conf-req SENT messages (less then 10) - and then a Term-REQ: - -> check whether your ISDN card is well configured - it seems, that your machine doesn't dial - (IRQ,IO,Proto, etc problems) - Configure your ISDN card to print debug messages and - check the /dev/isdnctrl output next time. There - you can see, whether there is activity on the card/line. - - there are at least a few RECV messages in the log: - -> fine: your card is dialing and your remote machine - tries to talk with you. Maybe only a missing - authentication. Check your ipppd configuration again. - - the ipppd exits for some reason: - -> not good ... check /var/adm/syslog and /var/adm/daemon. - Could be a bug in the ipppd. - --- - -Q12: How can I reduce login delay? - -A: Log a login session ('debug' log) and check which options - your remote side rejects. Next time configure your ipppd - to not negotiate these options. Another 'side effect' is, that - this increases redundancy. (e.g your remote side is buggy and - rejects options in a wrong way). - - - diff --git a/Documentation/process/changes.rst b/Documentation/process/changes.rst index 18735dc460a0..111636ad1bad 100644 --- a/Documentation/process/changes.rst +++ b/Documentation/process/changes.rst @@ -23,8 +23,8 @@ running, the suggested command should tell you.

The API is a prototype version from PPP where only - some (de)compressors have yet been implemented and all of them are - rather simple in their reset handling. Especially, their is only one - outstanding ResetAck at a time with all of them and ResetReq/-Acks do - not have parameters. For this very special case it was sufficient to - just return an error code from the decompressor and have a single - reset() entry to communicate all the necessary information between - the framework and the (de)compressor. Bad enough, LZS is different - (and any other compressor may be different, too). It has multiple - histories (eventually) and needs to Reset each of them independently - and thus uses multiple outstanding Acks and history numbers as an - additional parameter to Reqs/Acks. - All that makes it harder to port the reset state engine into the - kernel because it is not just the same simple one as in (i)pppd but - it must be able to pass additional parameters and have multiple out- - standing Acks. We are trying to achieve the impossible by handling - reset transactions independent by their id. The id MUST change when - the data portion changes, thus any (de)compressor who uses more than - one resettable state must provide and recognize individual ids for - each individual reset transaction.
