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

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

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 ...

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= 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 DebugCmd 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 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 2 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 9 default is HiSax, if you didn't specify one, where 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: 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 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 lilo 3. in case the hisax driver is a "fixed" part of the kernel, configure the driver with lilo: vi /etc/lilo.conf 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 !!!
