- * this code is nothing but a big dynamic switch to multiplex and demultiplex
- * layer 1 hardware isdn drivers to a common layer 2.
- *
- * when a card is successfully attached at system boot time, the driver for
- * this card calls the routine i4b_l1_mph_status_ind() with status = STI_ATTACH.
- *
- * This command is used to setup the tables for converting a "driver unit" and
- * "driver type" pair (encoded in the calls from the hardware driver to the
- * routines in this source file) to a "unit number" used in layer 2 and the
- * layers above (up to and including the isdnd daemon) and for converting
- * layer 2 units back to calling the appropriate driver and driver unit
- * number.
- *
- * Example: in my setup, a Winbond (iwic) card is probed first and gets
- * driver unit number 0, driver type 1 in layer 1. This becomes unit
- * number 0 in layer 2 and up. The second card probed is a Teles card
- * (isic) and gets driver unit number 0, driver type 0 in layer 1. This
- * becomes unit number 1 in layer 1 and up.
- *
- * To add support for a new driver, add a new driver number to i4b_l1.h:
- * currently we have L1DRVR_ISIC and L1DRVR_IWIC, so you would add
- * L1DRVR_FOO. More you would want to add a L0FOOUNIT to encode unit
- * numbers in your driver. You then have to add a l1foounittab[] and
- * add an entry to the getl1tab() routine for your driver. The only
- * thing left now is to write your driver with the support functions
- * for this multiplexer ;-)

-/* NOTES:
-
- This driver was written for the Dynalink IS64PH ISDN TA, based on two
- Siemens chips (HSCX 21525 and ISAC 2186). It is sold in the Netherlands.
-
- model numbers found on (my) card:
- IS64PH, TAS100H-N, P/N:89590555, TA200S100045521
-
- chips:
- Siemens PSB 21525N, HSCX TE V2.1
- Siemens PSB 2186N, ISAC-S TE V1.1
- 95MS14, PNP
-
- plug-and-play info:
- device id "ASU1688"
- vendor id 0x88167506
- serial 0x00000044
- i/o port 4 byte alignment, 4 bytes requested,
- 10 bit i/o decoding, 0x100-0x3f8 (?)
- irq 3,4,5,9,10,11,12,15, high true, edge sensitive
-
- At the moment I'm writing this Dynalink is replacing this card with
- one based on a single Siemens chip (IPAC). It will apparently be sold
- under the same model name.
-
- This driver might also work for Asuscom cards.

- * isic - I4B Siemens ISDN Chipset Driver for Asuscom ISDNlink 128K PnP
- * =====================================================================
- *
- * This driver works with Asuscom ISDNlink 128K PnP ISA adapter,
- * which is based on Siemens IPAC chip (my card probes as ASU1690).
- * Older Asuscom ISA cards are based on different chipset
- * (containing two chips) - for those cards, one might want
- * to try the Dynalink driver.
- *
- * This driver is heavily based on ELSA Quickstep 1000pro PCI
- * driver written by Hellmuth Michaelis. Card initialization
- * code is modeled after Linux i4l driver written by Karsten
- * Keil.

- * i4b_itk_ix1.c - ITK ix1 micro passive card driver for isdn4bsd
- * --------------------------------------------------------------
- * last edit-date: [Wed Jan 24 09:27:06 2001]
- *
- *---------------------------------------------------------------------------
- *
- * The ITK ix1 micro ISDN card is an ISA card with one region
- * of four io ports mapped and a fixed irq all jumpered on the card.
- * Access to the board is straight forward and simmilar to
- * the ELSA and DYNALINK cards. If a PCI version of this card
- * exists all we need is probably a pci-bus attachment, all
- * this low level routines should work imediately.
- *
- * To reset the card:
- * - write 0x01 to ITK_CONFIG
- * - wait >= 10 ms
- * - write 0x00 to ITK_CONFIG
- *
- * To read or write data:
- * - write address to ITK_ALE port
- * - read data from or write data to ITK_ISAC_DATA port or ITK_HSCX_DATA port
- * The two HSCX channel registers are offset by HSCXA (0x00) and HSCXB (0x40).
- *
- * The probe routine was derived by trial and error from a representative
- * sample of two cards ;-) The standard way (checking HSCX versions)
- * was extended by reading a zero from a non existant HSCX register (register
- * 0xff). Reading the config register gives varying results, so this doesn't
- * seem to be used as an id register (like the Teles S0/16.3).
- *
- * If the probe fails for your card use "options ITK_PROBE_DEBUG" to get
- * additional debug output.

-Message-ID: <3AF56886.7D92609A at cubical.fi>
-Date: Sun, 06 May 2001 18:06:47 +0300
-From: Juha-Matti Liukkonen <jml at cubical.fi>
-Organization: Cubical Solutions Ltd
-
-Please find the attached diff and tarball for our support software for
-CAPI 2.0 and AVM's active T1 and T1-B (primary rate) and B1 (basic rate)
-ISDN adapters for isdn4bsd. The implementation has been made from
-scratch by us, based on reverse engineering of the Linux driver provided
-by AVM GmbH and available in ftp.avm.de. Cubical Solutions Ltd offers
-this implementation for the BSD community free of charge and assuming
-absolutely no liabilities whatsoever. Feel free to modify the
-implementation any way you see fit, but please retain our one-liner
-copyright statement somewhere in the comment headers in the capi and
-iavc driver modules.
-
-That said, the attached tarball is i4b-00.96.00-beta with our
-modifications integrated, and the diff contains all modifications we
-have made to the original (including the new capi files). Our mods add
-pseudo-device i4bcapi, which attaches to i4b layer 4, and device iavc0,
-which implements a link layer driver for AVM's active B1 and T1 adapters
-for i4bcapi. There are also a couple of related improvements to isdnd,
-and a number of modifications to isdnd and layer 4 to implement support
-for up to 30 channels per adapter (for primary rate use).
-
-We have developed the software explicitly for our telephony application,
-to be used with AVM's T1 adapters, and the implementation has been
-tested primarily with this functionality in mind. There may be
-interesting side effects with eg. the ipr and isppp drivers; we do not
-use them and therefore their testing has been cursory at best. The
-i4btel driver works well with the T1 (our primary use), and the i4brbch
-driver has been verified to work with T1, T1-B and B1 adapters (ftp'd
-some files over a dialup PPP connection with each adapter). Only the PCI
-versions of the adapters (equipped with the AMCC DMA controller) are
-supported, although the basics (PIO mode communication) for the older
-ISA model support is in place, so only the bus attachment modules should
-be required to support the older hardware.
-
-All of the AVM active adapters use downloadable firmware, which is not
-included in the attached package. The firmware files (t1.t4, t1b.t4,
-b1.t4) can be found from ftp.avm.de in adapter specific subdirectories,
-or from the CDs provided with the adapters (in directory
-'cardware/firmware').
-
-Our primary development platform is our own embedded build (we call it
-'ebsd') based on FreeBSD 4.2-RELEASE. The implementation has also been
-tested on standard FreeBSD 4.2-RELEASE system. The implementation should
-not contain any FreeBSD (or even FreeBSD release) specific issues, but
-it has not been tested or even compiled on any other platforms;
-specifically, only the FreeBSD overinstall.sh script is modified to
-install the capi/iavc support in the kernel source tree.
-
-This code is not under active development here since the functionality
-we use (i4btel, T1) has been working since the beginning of March. We
-are also not planning on any further development (no need seen at this
-point), but I am naturally interested on whatever bugs and development
-ideas pop up on the community and will keep a keen eye on the isdn
-mailing list. I personally may be available for consultation, debugging
-and possibly development projects, but with notable reservations on my
-time (the current IT industry recession seems to be pushing even more
-work for us, which tends to keep us pretty busy these days).
-
-Here are some specific technical notes:
-
-* isdnd supports new keyword 'firmware=</path/to/file>' in section
-'controller'. This keyword is supported for all controller types, and
-causes I4B_CTRL_DOWNLOAD ioctl to be invoked with the specified file as
-an argument. In systems equipped with both active and passive adapters,
-and the passive cards being detected first, dummy 'controller' entries
-are required for the passive cards to get the correct firmwares to
-correct adapters. (I hope you did not have other uses for this ioctl in
-mind?)
-
-* isdnd supports new keyword 'clone=<entry name>' in section 'entry'.
-This causes the entry to be copied from the existing named entry. At
-least entry specific 'name' and 'usrdeviceunit' values should be
-specified after a 'clone'. (Makes configuring 30 or 60 entries way much
-easier.)
-
-* a bug in i4btel driver read routine corrected. The conditions in the
-while() clause caused the receive queue to be referenced before checking
-if a channel is connected, leading to kernel panic (do a 'dd
-if=/dev/i4btel0 of=/dev/null' on an unconnected tel device, panic will
-follow). Correction was to reorder the while clause conditions to check
-for connectedness first.
-
-* isdnd and i4b layer 4 support up to CHANNELS_MAX (=30) channels per
-adapter. The msg_ctrl_info_req_t message reports the number of channels
-provided by the adapter, the number is stored in the nbchan field of the
-controller state structure. The fixed stateb1 and stateb2 entries in
-controller state stuctures are replaced with an array, and all fixed
-references there are replaced with loops up to nbchan. Passive stack
-layer 1 and 2 are not modified, layer 3 sets this field to fixed value 2
-for all adapters (but it could be delegated to the layer 1 driver's
-attach request).
-
-* the i4bcapi driver maps i4b channels to logical channels identified
-with PLCI/NCCI values in the CAPI protocol using the sc_bchan[] array.
-The PLCI/NCCI handling is merged in the channel mapping and is greatly
-simplified from the reference state machine model, because in practice
-there can be only one PLCI/NCCI per channel active at any given time.
-
-* the i4bcapi driver does not provide any kind of user level interface
-(such as the /dev/capi20 interface provided by the linux driver), but
-could relatively easily be extended to do so (and if done, interface
-compatibility with the linux implementation would probably be a good
-goal).
-
-* there are some gritty details in the iavc driver, inherited from the
-linux code. Despite us being a legitimate company in the telecom
-business, AVM failed to produce any programming reference material for
-us (at least in a reasonable time frame), so some guesswork remains due
-to classic reverse engineering process (particularly there are a few
-magic numbers in the card initialization sequence whose meaning I do not
-know).
-
-* pseudo-devices i4bq931, i4bq921 and some passive stack layer 1 driver
-(such as iwic) are required to compile, as the required ctrl_desc[]
-array is in layer 3, which requires layer 2, which requires layer 1.
-Some architectural cleanup would come in handy here, but we did not want
-to start making any major changes (and we use iwic in test setups
-anyway, so we simply always compile it in).
-
-To summarize: unpack, overinstall, add the following lines (with the
-usual passive stack configuration including at least one L1 driver) to
-your kernel configuration file:
-
-pseudo-device "i4bcapi"
-device iavc0
-
-...and the following to your isdnd.rc:
-
-controller
-firmware = /usr/lib/isdn/b1.t4
-
-...compile your new kernel, make sure the firmware file is in
-/usr/lib/isdn, and your B1 adapter should boot up and Just Work (tm). If
-you have multiple adapters, you need a 'controller' section for each to
-have them loaded and booted on isdnd startup.
-
-Have fun -- and let me know if there are any complications, or if I can
-be of further assistance,
-

-
-
- unitlen - specifies the time a charging unit lasts
- idle_time - specifies the thime the line must be idle at the
- end of the unit to be elected for hangup
- earlyhup - is the beginning of a timing safety zone before the
- next charging unit starts
-
- The algorithm works as follows: lets assume the unitlen is 100
- secons, idle_time is 40 seconds and earlyhup is 10 seconds.
- The line then must be idle 50 seconds after the begin of the
- current unit and it must then be quiet for 40 seconds. if it
- has been quiet for this 40 seconds, the line is closed 10
- seconds before the next charging unit starts. In case there was
- any traffic within the idle_time, the line is not closed.
- It does not matter whether there was any traffic between second
- 0 and second 50 or not.
-
-
- How shorthold mode works for INCOMING connections
- =================================================
-
- it is just possible to specify a maximum idle time for incoming
- connections, after this time of no activity on the line the line
- is closed.
