A ISA-, MCA-, and PCMCIA-Bus +Version. Currently, only the ISA-Bus version of the card is supported. +However MCA and PCMCIA will follow soon. + +The ISA-Bus Version uses 8 IO-ports. The base port address has to be set +manually using the DIP switches. + +Setting up the DIP switches for the IBM Active 2000 ISDN card: + + Note: S5 and S6 always set off! + + S1 S2 S3 S4 Base-port + on on on on 0x0200 (Factory default) + off on on on 0x0240 + on off on on 0x0280 + off off on on 0x02c0 + on on off on 0x0300 + off on off on 0x0340 + on off off on 0x0380 + on on on off 0xcfe0 + off on on off 0xcfa0 + on off on off 0xcf60 + off off on off 0xcf20 + on on off off 0xcee0 + off on off off 0xcea0 + on off off off 0xce60 + off off off off Card disabled + +IRQ is configured by software. Possible values are: + + 3, 5, 7, 10, 11, 12, 15 and none (polled mode) + + +The ACT2000 driver may either be built into the kernel or as a module. +Initialization depends on how the driver is built: + +Driver built into the kernel: + + The ACT2000 driver can be configured using the commandline-feature while + loading the kernel with LILO or LOADLIN. It accepts the following syntax: + + act2000=b,p,i[,idstring] + + where + + b = Bus-Type (1=ISA, 2=MCA, 3=PCMCIA) + p = portbase (-1 means autoprobe) + i = Interrupt (-1 means use next free IRQ, 0 means polled mode) + + The idstring is an arbitrary string used for referencing the card + by the actctrl tool later. + + Defaults used, when no parameters given at all: + + 1,-1,-1,"" + + which means: Autoprobe for an ISA card, use next free IRQ, let the + ISDN linklevel fill the IdString (usually "line0" for the first card). + + If you like to use more than one card, you can use the program + "actctrl" from the utility-package to configure additional cards. + + Using the "actctrl"-utility, portbase and irq can also be changed + during runtime. The D-channel protocol is configured by the "dproto" + option of the "actctrl"-utility after loading the firmware into the + card's memory using the "actctrl"-utility. + +Driver built as module: + + The module act2000.o can be configured during modprobe (insmod) by + appending its parameters to the modprobe resp. insmod commandline. + The following syntax is accepted: + + act_bus=b act_port=p act_irq=i act_id=idstring + + where b, p, i and idstring have the same meanings as the parameters + described for the builtin version above. + + Using the "actctrl"-utility, the same features apply to the modularized + version as to the kernel-builtin one. (i.e. loading of firmware and + configuring the D-channel protocol) + +Loading the firmware into the card: + + The firmware is supplied together with the isdn4k-utils package. It + can be found in the subdirectory act2000/firmware/ + + Assuming you have installed the utility-package correctly, the firmware + will be downloaded into the card using the following command: + + actctrl -d idstring load /etc/isdn/bip11.btl + + where idstring is the Name of the card, given during insmod-time or + (for kernel-builtin driver) on the kernel commandline. If only one + ISDN card is used, the -d isdstrin may be omitted. + + For further documentation (adding more IBM Active 2000 cards), refer to + the manpage actctrl.8 which is included in the isdn4k-utils package. + |
