1HiSax is a Linux hardware-level driver for passive ISDN cards with Siemens
2chipset (ISAC_S 2085/2086/2186, HSCX SAB 82525). It is based on the Teles
3driver from Jan den Ouden.
4It is meant to be used with isdn4linux, an ISDN link-level module for Linux
5written by Fritz Elfert.

79You can combine any card, if there is no conflict between the resources
80(io, mem, irq).

83Configuring the driver
84----------------------
85
86The HiSax driver can either be built directly into the kernel or as a module.
87It can be configured using the command line feature while loading the kernel
88with LILO or LOADLIN or, if built as a module, using insmod/modprobe with
89parameters.
90There is also some config needed before you compile the kernel and/or
91modules. It is included in the normal "make [menu]config" target at the
92kernel. Don't forget it, especially to select the right D-channel protocol.
93
94Please note: In older versions of the HiSax driver, all PnP cards
95needed to be configured with isapnp and worked only with the HiSax
96driver used as a module.
97
98In the current version, HiSax will automatically use the in-kernel
99ISAPnP support, provided you selected it during kernel configuration
100(CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters.
101
102The affected card types are: 4,7,12,14,19,27-30
103
104a) when built as a module
105-------------------------
106
107insmod/modprobe  hisax.o \
108  io=iobase irq=IRQ mem=membase type=card_type \
109  protocol=D_channel_protocol id=idstring
110
111or, if several cards are installed:
112
113insmod/modprobe hisax.o \
114  io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \
115  type=card_type1,card_type2,... \
116  protocol=D_channel_protocol1,D_channel_protocol2,... \
117  id=idstring1%idstring2 ...
118
119where "iobaseN" represents the I/O base address of the Nth card, "membaseN"
120the memory base address of the Nth card, etc.
121
122The reason for the delimiter "%" being used in the idstrings is that ","
123won't work with the current modules package.
124
125The parameters may be specified in any order. For example, the "io"
126parameter may precede the "irq" parameter, or vice versa. If several
127cards are installed, the ordering within the comma separated parameter
128lists must of course be consistent.
129
130Only parameters applicable to the card type need to be specified. For
131example, the Teles 16.3 card is not memory-mapped, so the "mem"
132parameter may be omitted for this card. Sometimes it may be necessary
133to specify a dummy parameter, however. This is the case when there is
134a card of a different type later in the list that needs a parameter
135which the preceding card does not. For instance, if a Teles 16.0 card
136is listed after a Teles 16.3 card, a dummy memory base parameter of 0
137must be specified for the 16.3. Instead of a dummy value, the parameter
138can also be skipped by simply omitting the value. For example:
139mem=,0xd0000. See example 6 below.
140
141The parameter for the D-Channel protocol may be omitted if you selected the
142correct one during kernel config. Valid values are "1" for German 1TR6,
143"2" for EDSS1 (Euro ISDN), "3" for leased lines (no D-Channel) and "4"
144for US NI1.
145With US NI1 you have to include your SPID into the MSN setting in the form
146<MSN>:<SPID> for example (your phonenumber is 1234 your SPID 5678):
147AT&E1234:5678                       on ttyI interfaces
148isdnctrl eaz ippp0 1234:5678        on network devices
149
150The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying
151the I/O addresses of the ISAC and HSCX chips, respectively.

321Running the driver
322------------------
323
324When you insmod isdn.o and hisax.o (or with the in-kernel version, during
325boot time), a few lines should appear in your syslog. Look for something like:
326
327Apr 13 21:01:59 kke01 kernel: HiSax: Driver for Siemens chip set ISDN cards
328Apr 13 21:01:59 kke01 kernel: HiSax: Version 2.9
329Apr 13 21:01:59 kke01 kernel: HiSax: Revisions 1.14/1.9/1.10/1.25/1.8

332Apr 13 21:01:59 kke01 kernel: HiSax: Elsa driver Rev. 1.13
333...
334Apr 13 21:01:59 kke01 kernel: Elsa: PCF-Pro found at 0x360 Rev.:C IRQ 10
335Apr 13 21:01:59 kke01 kernel: Elsa: timer OK; resetting card
336Apr 13 21:01:59 kke01 kernel: Elsa: HSCX version A: V2.1  B: V2.1
337Apr 13 21:01:59 kke01 kernel: Elsa: ISAC 2086/2186 V1.1
338...
339Apr 13 21:01:59 kke01 kernel: HiSax: DSS1 Rev. 1.14
340Apr 13 21:01:59 kke01 kernel: HiSax: 2 channels added
341
342This means that the card is ready for use.
343Cabling problems or line-downs are not detected, and only some ELSA cards can
344detect the S0 power.
345
346Remember that, according to the new strategy for accessing low-level drivers
347from within isdn4linux, you should also define a driver ID while doing
348insmod: Simply append hisax_id=<SomeString> to the insmod command line. This
349string MUST NOT start with a digit or a small 'x'!
350
351At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages.
352
353At the moment, debugging messages are enabled with the hisaxctrl tool:
354
355    hisaxctrl <DriverId> DebugCmd <debugging_flags>
356
357<DriverId> default is HiSax, if you didn't specify one.
358
359DebugCmd is  1  for generic debugging
360            11  for layer 1 development debugging
361            13  for layer 3 development debugging
362
363where <debugging_flags> is the integer sum of the following debugging
364options you wish enabled:
365
366With DebugCmd set to 1:
367
368   0x0001  Link-level <--> hardware-level communication
369   0x0002  Top state machine
370   0x0004  D-Channel Frames for isdnlog
371   0x0008  D-Channel Q.921
372   0x0010  B-Channel X.75
373   0x0020  D-Channel l2

404
405For example, 'hisaxctrl HiSax 1 0x3ff' enables full generic debugging.
406
407Because of some obscure problems with some switch equipment, the delay
408between the CONNECT message and sending the first data on the B-channel is now
409configurable with
410
411hisaxctrl <DriverId> 2 <delay>
412<delay> in ms Value between 50 and 800 ms is recommended.
413
414Downloading Firmware
415--------------------
416At the moment, the Sedlbauer speed fax+ is the only card, which
417needs to download firmware.
418The firmware is downloaded with the hisaxctrl tool:
419
420    hisaxctrl <DriverId> 9 <firmware_filename>
421
422<DriverId> default is HiSax, if you didn't specify one,
423
424where <firmware_filename> is the filename of the firmware file.
425
426For example, 'hisaxctrl HiSax 9 ISAR.BIN' downloads the firmware for
427ISAR based cards (like the Sedlbauer speed fax+).
428
429Warning
430-------
431HiSax is a work in progress and may crash your machine.
432For certification look at HiSax.cert file.
433
434Limitations
435-----------
436At this time, HiSax only works on Euro ISDN lines and German 1TR6 lines.
437For leased lines see appendix.
438
439Bugs

492Appendix: Linux and ISDN-leased lines
493-------------------------------------
494
495Original from Juergen Quade, new version KKe.
496
497Attention NEW VERSION, the old leased line syntax won't work !!!
498
499You can use HiSax to connect your Linux-Box via an ISDN leased line
500to e.g. the Internet:
501
5021. Build a kernel which includes the HiSax driver either as a module
503   or as part of the kernel.
504     cd /usr/src/linux
505     make menuconfig
506     <ISDN subsystem - ISDN support -- HiSax>
507     make clean; make zImage; make modules; make modules_install
5082. Install the new kernel
509     cp /usr/src/linux/arch/x86/boot/zImage /etc/kernel/linux.isdn
510     vi /etc/lilo.conf
511     <add new kernel in the bootable image section>
512     lilo
5133. in case the hisax driver is a "fixed" part of the kernel, configure
514   the driver with lilo:
515     vi /etc/lilo.conf
516     <add HiSax driver parameter in the global section (see below)>
517     lilo
518   Your lilo.conf _might_ look like the following:
519
520	# LILO configuration-file
521	# global section
522    # teles 16.0 on IRQ=5, MEM=0xd8000, PORT=0xd80
523	append="hisax=1,3,5,0xd8000,0xd80,HiSax"
524    # teles 16.3 (non pnp) on IRQ=15, PORT=0xd80
525	# append="hisax=3,3,5,0xd8000,0xd80,HiSax"
526	boot=/dev/sda
527	compact        # faster, but won't work on all systems.
528	linear
529	read-only
530	prompt
531	timeout=100
532	vga = normal    # force sane state
533	# Linux bootable partition config begins
534	image = /etc/kernel/linux.isdn
535	root = /dev/sda1
536	label = linux.isdn
537	#
538	image = /etc/kernel/linux-2.0.30
539	root = /dev/sda1
540	label = linux.secure
541
542   In the line starting with "append" you have to adapt the parameters
543   according to your card (see above in this file)
544
5453. boot the new linux.isdn kernel
5464. start the ISDN subsystem:
547   a) load - if necessary - the modules (depends, whether you compiled
548      the ISDN driver as module or not)
549      According to the type of card you have to specify the necessary
550      driver parameter (irq, io, mem, type, protocol).
551      For the leased line the protocol is "3". See the table above for
552      the parameters, which you have to specify depending on your card.
553   b) configure i4l
554      /sbin/isdnctrl addif isdn0
555      # EAZ  1 -- B1 channel   2 --B2 channel
556      /sbin/isdnctrl eaz isdn0 1
557      /sbin/isdnctrl secure isdn0 on
558      /sbin/isdnctrl huptimeout isdn0 0
559      /sbin/isdnctrl l2_prot isdn0 hdlc
560      # Attention you must not set an outgoing number !!! This won't work !!!
561      # The incoming number is LEASED0 for the first card, LEASED1 for the
562      # second and so on.
563      /sbin/isdnctrl addphone isdn0 in LEASED0
564      # Here is no need to bind the channel.
565   c) in case the remote partner is a CISCO:
566      /sbin/isdnctrl encap isdn0 cisco-h
567   d) configure the interface
568      /sbin/ifconfig isdn0 ${LOCAL_IP} pointopoint ${REMOTE_IP}
569   e) set the routes
570      /sbin/route add -host ${REMOTE_IP} isdn0
571      /sbin/route add default gw ${REMOTE_IP}
572   f) switch the card into leased mode for each used B-channel
573      /sbin/hisaxctrl HiSax 5 1
574
575Remarks:
576a) Use state of the art isdn4k-utils
577
