-
-However, if you wish to modify the HiSax sources, please note the following:
-
-HiSax has passed the ITU approval test suite with ELSA Quickstep ISDN cards
-and Eicon Technology Diva 2.01 PCI card.
-The certification is only valid for the combination of the tested software
-version and the tested hardware. Any changes to the HiSax source code may
-therefore affect the certification.
-
-Additional ITU approval tests have been carried out for all generic cards
-using Colognechip single chip solutions HFC-S PCI A for PCI cards as well
-as HFC-S USB based USB ISDN ta adapters.
-These tests included all layers 1-3 and as well all functional tests for
-the layer 1. Because all hardware based on these chips are complete ISDN
-solutions in one chip all cards and USB-TAs using these chips are to be
-regarded as approved for those tests. Some additional electrical tests
-of the layer 1 which are independent of the driver and related to a
-special hardware used will be regarded as approved if at least one
-solution has been tested including those electrical tests. So if cards
-or tas have been completely approved for any other os, the approval
-for those electrical tests is valid for linux, too.
-Please send any questions regarding this drivers or approval abouts to
-werner@isdn-development.de
-Additional information and the type approval documents will be found
-shortly on the Colognechip website www.colognechip.com
-
-If you change the main files of the HiSax ISDN stack, the certification will
-become invalid. Because in most countries it is illegal to connect
-unapproved ISDN equipment to the public network, I have to guarantee that
-changes in HiSax do not affect the certification.
-
-In order to make a valid certification apparent to the user, I have built in
-some validation checks that are made during the make process. The HiSax main
-files are protected by md5 checksums and the md5sum file is pgp signed by
-myself:
-
-KeyID 1024/FF992F6D 1997/01/16 Karsten Keil <kkeil@suse.de>
-Key fingerprint = 92 6B F7 58 EE 86 28 C8 C4 1A E6 DC 39 89 F2 AA
-
-Only if the checksums are OK, and the signature of the file
-"drivers/isdn/hisax/md5sums.asc" match, is the certification valid; a
-message confirming this is then displayed during the hisax init process.

-
-
-Configuring the driver
-----------------------
-
-The HiSax driver can either be built directly into the kernel or as a module.
-It can be configured using the command line feature while loading the kernel
-with LILO or LOADLIN or, if built as a module, using insmod/modprobe with
-parameters.
-There is also some config needed before you compile the kernel and/or
-modules. It is included in the normal "make [menu]config" target at the
-kernel. Don't forget it, especially to select the right D-channel protocol.
-
-Please note: In older versions of the HiSax driver, all PnP cards
-needed to be configured with isapnp and worked only with the HiSax
-driver used as a module.
-
-In the current version, HiSax will automatically use the in-kernel
-ISAPnP support, provided you selected it during kernel configuration
-(CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters.
-
-The affected card types are: 4,7,12,14,19,27-30
-
-a) when built as a module
--------------------------
-
-insmod/modprobe hisax.o \
- io=iobase irq=IRQ mem=membase type=card_type \
- protocol=D_channel_protocol id=idstring
-
-or, if several cards are installed:
-
-insmod/modprobe hisax.o \
- io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \
- type=card_type1,card_type2,... \
- protocol=D_channel_protocol1,D_channel_protocol2,... \
- id=idstring1%idstring2 ...
-
-where "iobaseN" represents the I/O base address of the Nth card, "membaseN"
-the memory base address of the Nth card, etc.
-
-The reason for the delimiter "%" being used in the idstrings is that ","
-won't work with the current modules package.
-
-The parameters may be specified in any order. For example, the "io"
-parameter may precede the "irq" parameter, or vice versa. If several
-cards are installed, the ordering within the comma separated parameter
-lists must of course be consistent.
-
-Only parameters applicable to the card type need to be specified. For
-example, the Teles 16.3 card is not memory-mapped, so the "mem"
-parameter may be omitted for this card. Sometimes it may be necessary
-to specify a dummy parameter, however. This is the case when there is
-a card of a different type later in the list that needs a parameter
-which the preceding card does not. For instance, if a Teles 16.0 card
-is listed after a Teles 16.3 card, a dummy memory base parameter of 0
-must be specified for the 16.3. Instead of a dummy value, the parameter
-can also be skipped by simply omitting the value. For example:
-mem=,0xd0000. See example 6 below.
-
-The parameter for the D-Channel protocol may be omitted if you selected the
-correct one during kernel config. Valid values are "1" for German 1TR6,
-"2" for EDSS1 (Euro ISDN), "3" for leased lines (no D-Channel) and "4"
-for US NI1.
-With US NI1 you have to include your SPID into the MSN setting in the form
-<MSN>:<SPID> for example (your phonenumber is 1234 your SPID 5678):
-AT&E1234:5678 on ttyI interfaces
-isdnctrl eaz ippp0 1234:5678 on network devices
-
-The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying
-the I/O addresses of the ISAC and HSCX chips, respectively.
-
-Card types:
-
- Type Required parameters (in addition to type and protocol)
-
- 1 Teles 16.0 irq, mem, io

- modprobe hisax protocol=1 type=1 io=0xd80 mem=0xd0000 irq=5
-
-3. Fritzcard, Euro ISDN, I/O base 340 hex, IRQ 10 and ELSA PCF, Euro ISDN
- modprobe hisax type=5,6 protocol=2,2 io=0x340 irq=10 id=Fritz%Elsa
-
-4. Any ELSA PCC/PCF card, Euro ISDN
- modprobe hisax type=6 protocol=2
-
-5. Teles 16.3 PnP, Euro ISDN, with isapnp configured
- isapnp config: (INT 0 (IRQ 10 (MODE +E)))

- (IO 1 (BASE 0x0180))
- modprobe hisax type=4 protocol=2 irq=10 io0=0x580 io1=0x180
-
- In the current version of HiSax, you can instead simply use
-
- modprobe hisax type=4 protocol=2
-
- if you configured your kernel for ISAPnP. Don't run isapnp in
- this case!

-Running the driver
-------------------
-
-When you insmod isdn.o and hisax.o (or with the in-kernel version, during
-boot time), a few lines should appear in your syslog. Look for something like:
-
-Apr 13 21:01:59 kke01 kernel: HiSax: Driver for Siemens chip set ISDN cards
-Apr 13 21:01:59 kke01 kernel: HiSax: Version 2.9
-Apr 13 21:01:59 kke01 kernel: HiSax: Revisions 1.14/1.9/1.10/1.25/1.8
-Apr 13 21:01:59 kke01 kernel: HiSax: Total 1 card defined
-Apr 13 21:01:59 kke01 kernel: HiSax: Card 1 Protocol EDSS1 Id=HiSax1 (0)
-Apr 13 21:01:59 kke01 kernel: HiSax: Elsa driver Rev. 1.13
-...
-Apr 13 21:01:59 kke01 kernel: Elsa: PCF-Pro found at 0x360 Rev.:C IRQ 10
-Apr 13 21:01:59 kke01 kernel: Elsa: timer OK; resetting card
-Apr 13 21:01:59 kke01 kernel: Elsa: HSCX version A: V2.1 B: V2.1
-Apr 13 21:01:59 kke01 kernel: Elsa: ISAC 2086/2186 V1.1
-...
-Apr 13 21:01:59 kke01 kernel: HiSax: DSS1 Rev. 1.14
-Apr 13 21:01:59 kke01 kernel: HiSax: 2 channels added
-
-This means that the card is ready for use.
-Cabling problems or line-downs are not detected, and only some ELSA cards can
-detect the S0 power.
-
-Remember that, according to the new strategy for accessing low-level drivers
-from within isdn4linux, you should also define a driver ID while doing
-insmod: Simply append hisax_id=<SomeString> to the insmod command line. This
-string MUST NOT start with a digit or a small 'x'!
-
-At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages.
-
-At the moment, debugging messages are enabled with the hisaxctrl tool:
-
- hisaxctrl <DriverId> DebugCmd <debugging_flags>
-
-<DriverId> default is HiSax, if you didn't specify one.
-
-DebugCmd is 1 for generic debugging
- 11 for layer 1 development debugging
- 13 for layer 3 development debugging
-
-where <debugging_flags> is the integer sum of the following debugging
-options you wish enabled:
-
-With DebugCmd set to 1:
-
- 0x0001 Link-level <--> hardware-level communication
- 0x0002 Top state machine
- 0x0004 D-Channel Frames for isdnlog
- 0x0008 D-Channel Q.921
- 0x0010 B-Channel X.75
- 0x0020 D-Channel l2
- 0x0040 B-Channel l2
- 0x0080 D-Channel link state debugging
- 0x0100 B-Channel link state debugging
- 0x0200 TEI debug
- 0x0400 LOCK debug in callc.c
- 0x0800 More paranoid debug in callc.c (not for normal use)
- 0x1000 D-Channel l1 state debugging
- 0x2000 B-Channel l1 state debugging
-
-With DebugCmd set to 11:
-
- 0x0001 Warnings (default: on)
- 0x0002 IRQ status
- 0x0004 ISAC
- 0x0008 ISAC FIFO
- 0x0010 HSCX
- 0x0020 HSCX FIFO (attention: full B-Channel output!)
- 0x0040 D-Channel LAPD frame types
- 0x0080 IPAC debug
- 0x0100 HFC receive debug
- 0x0200 ISAC monitor debug
- 0x0400 D-Channel frames for isdnlog (set with 1 0x4 too)
- 0x0800 D-Channel message verbose
-
-With DebugCmd set to 13:
-
- 1 Warnings (default: on)
- 2 l3 protocol descriptor errors
- 4 l3 state machine
- 8 charge info debugging (1TR6)
-
-For example, 'hisaxctrl HiSax 1 0x3ff' enables full generic debugging.
-
-Because of some obscure problems with some switch equipment, the delay
-between the CONNECT message and sending the first data on the B-channel is now
-configurable with
-
-hisaxctrl <DriverId> 2 <delay>
-<delay> in ms Value between 50 and 800 ms is recommended.
-
-Downloading Firmware
---------------------
-At the moment, the Sedlbauer speed fax+ is the only card, which
-needs to download firmware.
-The firmware is downloaded with the hisaxctrl tool:
-
- hisaxctrl <DriverId> 9 <firmware_filename>
-
-<DriverId> default is HiSax, if you didn't specify one,
-
-where <firmware_filename> is the filename of the firmware file.
-
-For example, 'hisaxctrl HiSax 9 ISAR.BIN' downloads the firmware for
-ISAR based cards (like the Sedlbauer speed fax+).
-
-Warning
--------
-HiSax is a work in progress and may crash your machine.
-For certification look at HiSax.cert file.
-
-Limitations
------------
-At this time, HiSax only works on Euro ISDN lines and German 1TR6 lines.
-For leased lines see appendix.
-

-Appendix: Teles PCMCIA driver
------------------------------
-
-See
- http://www.linux.no/teles_cs.txt
-for instructions.
-
-Appendix: Linux and ISDN-leased lines
--------------------------------------
-
-Original from Juergen Quade, new version KKe.
-
-Attention NEW VERSION, the old leased line syntax won't work !!!
-
-You can use HiSax to connect your Linux-Box via an ISDN leased line
-to e.g. the Internet:
-
-1. Build a kernel which includes the HiSax driver either as a module
- or as part of the kernel.
- cd /usr/src/linux
- make menuconfig
- <ISDN subsystem - ISDN support -- HiSax>
- make clean; make zImage; make modules; make modules_install
-2. Install the new kernel
- cp /usr/src/linux/arch/x86/boot/zImage /etc/kernel/linux.isdn
- vi /etc/lilo.conf
- <add new kernel in the bootable image section>
- lilo
-3. in case the hisax driver is a "fixed" part of the kernel, configure
- the driver with lilo:
- vi /etc/lilo.conf
- <add HiSax driver parameter in the global section (see below)>
- lilo
- Your lilo.conf _might_ look like the following:
-
- # LILO configuration-file
- # global section
- # teles 16.0 on IRQ=5, MEM=0xd8000, PORT=0xd80
- append="hisax=1,3,5,0xd8000,0xd80,HiSax"
- # teles 16.3 (non pnp) on IRQ=15, PORT=0xd80
- # append="hisax=3,3,5,0xd8000,0xd80,HiSax"
- boot=/dev/sda
- compact # faster, but won't work on all systems.
- linear
- read-only
- prompt
- timeout=100
- vga = normal # force sane state
- # Linux bootable partition config begins
- image = /etc/kernel/linux.isdn
- root = /dev/sda1
- label = linux.isdn
- #
- image = /etc/kernel/linux-2.0.30
- root = /dev/sda1
- label = linux.secure
-
- In the line starting with "append" you have to adapt the parameters
- according to your card (see above in this file)
-
-3. boot the new linux.isdn kernel
-4. start the ISDN subsystem:
- a) load - if necessary - the modules (depends, whether you compiled
- the ISDN driver as module or not)
- According to the type of card you have to specify the necessary
- driver parameter (irq, io, mem, type, protocol).
- For the leased line the protocol is "3". See the table above for
- the parameters, which you have to specify depending on your card.
- b) configure i4l
- /sbin/isdnctrl addif isdn0
- # EAZ 1 -- B1 channel 2 --B2 channel
- /sbin/isdnctrl eaz isdn0 1
- /sbin/isdnctrl secure isdn0 on
- /sbin/isdnctrl huptimeout isdn0 0
- /sbin/isdnctrl l2_prot isdn0 hdlc
- # Attention you must not set an outgoing number !!! This won't work !!!
- # The incoming number is LEASED0 for the first card, LEASED1 for the
- # second and so on.
- /sbin/isdnctrl addphone isdn0 in LEASED0
- # Here is no need to bind the channel.
- c) in case the remote partner is a CISCO:
- /sbin/isdnctrl encap isdn0 cisco-h
- d) configure the interface
- /sbin/ifconfig isdn0 ${LOCAL_IP} pointopoint ${REMOTE_IP}
- e) set the routes
- /sbin/route add -host ${REMOTE_IP} isdn0
- /sbin/route add default gw ${REMOTE_IP}
- f) switch the card into leased mode for each used B-channel
- /sbin/hisaxctrl HiSax 5 1
-
-Remarks:
-a) Use state of the art isdn4k-utils
-

- *
- * gerdes_amd7930.c Amd 79C30A and 79C32A specific routines
- * (based on HiSax driver by Karsten Keil)
- *
- * Author Christoph Ersfeld <info@formula-n.de>
- * Formula-n Europe AG (www.formula-n.com)
- * previously Gerdes AG
- *
- *
- * This file is (c) under GNU PUBLIC LICENSE
- *
- *
- * Notes:
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- *
- * Please don't report any malfunction to me without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- * Formula-n enter:now ISDN PCI and compatible
- * (f.e. Gerdes Power ISDN PCI)
- *
- * modprobe hisax type=41 protocol=2 id=gerdes
- *
- * if you chose an other value for id, you need to modify the
- * code below, too.
- *
- * 2. set debug-level
- *
- * hisaxctrl gerdes 1 0x3ff
- * hisaxctrl gerdes 11 0x4f
- * cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary this driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

-/* enternow_pci.c,v 0.99 2001/10/02
- *
- * enternow_pci.c Card-specific routines for
- * Formula-n enter:now ISDN PCI ab
- * Gerdes AG Power ISDN PCI
- * Woerltronic SA 16 PCI
- * (based on HiSax driver by Karsten Keil)
- *
- * Author Christoph Ersfeld <info@formula-n.de>
- * Formula-n Europe AG (www.formula-n.com)
- * previously Gerdes AG
- *
- *
- * This file is (c) under GNU PUBLIC LICENSE
- *
- * Notes:
- * This driver interfaces to netjet.c which performs B-channel
- * processing.
- *
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- * It isn't testet on linux 2.4 yet, so consider this code to be
- * beta.
- *
- * Please don't report me any malfunction without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- * Formula-n enter:now ISDN PCI and compatible
- * (f.e. Gerdes Power ISDN PCI)
- *
- * modprobe hisax type=41 protocol=2 id=gerdes
- *
- * if you chose an other value for id, you need to modify the
- * code below, too.
- *
- * 2. set debug-level
- *
- * hisaxctrl gerdes 1 0x3ff
- * hisaxctrl gerdes 11 0x4f
- * cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary the driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.
