NAME

     isic - isdn4bsd Siemens ISDN Chipset device driver

SYNOPSIS

     device isic

DESCRIPTION

     The isic driver provides D-channel layer 1 supports as specified in ITU
     Recommendation I.430 and layer 1 support for the B-channel.

     The driver supports several 8 and 16bit passive ISA, ISA PnP and PCI ISDN
     cards from various manufacturers which are all based upon the popular
     Siemens ISDN chipset consisting of the ISDN Subscriber Access Controller
     ISAC (such as the PEB2085 or PSB 2186) and the High-Level Serial
     Communications Controller Extended HSCX (such as the SAB82525 or
     PSB21525).  The newer IPAC chip (which integrates an ISAC and a HSCX in
     one chip, with the added benefit of larger FIFO buffers) is also
     supported.

SUPPORTED CARDS: ISA bus, NON-PnP

     Teles S0/8, Dr. Neuhaus Niccy 1008, Creatix ISDN-S0/8

             The required entry in the kernel config file is:

                   options TEL_S0_8

             The required entry in device.hints(5) file is:

                   hint.isic.0.at="isa"
                   hint.isic.0.maddr="0xd0000"
                   hint.isic.0.irq="5"
                   hint.isic.0.flags="1"

             Notice that this cards must not have a port value.

             Valid values for hint.isic.N.irq are 2, 3, 4, 5, 6 and 7.

             The i/o ports are memory mapped and the memory start address
             (hint.isic.N.maddr) may be in the range 0xA0000 to 0xDF000 and
             use a region of 4kB of memory.

     Teles S0/16, Creatix ISDN-S0, Dr. Neuhaus Niccy 1016

             The required entry in the kernel config file is:

                   options TEL_S0_16

             The required entry in device.hints(5) file is:

                   hint.isic.0.at="isa"
                   hint.isic.0.port="0xd80"
                   hint.isic.0.maddr="0xd0000"
                   hint.isic.0.irq="5"
                   hint.isic.0.flags="2"

             These boards have a jumper which specifies an i/o base address
             (hint.isic.N.port) of either 0xd80, 0xe80 or 0xf80.  The
             remaining necessary configuration values are then programmed at
             run time by accessing this i/o port.

             Valid interrupts (hint.isic.N.irq) are 2, 3, 4, 5, 10, 11, 12 or
             15.

             Valid memory start addresses (hint.isic.N.maddr) are 0xC0000,
             0xC2000, 0xC4000, 0xC6000, 0xC8000, 0xCA000, 0xCC000, 0xCE000,
             0xD0000, 0xD2000, 0xD4000, 0xD6000, 0xD8000, 0xDA000, 0xDC000 and
             0xDE000.

             Notice: Although the jumpers are labeled 0xd80, 0xe80 or 0xf80,
             they also require i/o space at addresses 0x180, 0x280 or 0x380.

     Teles S0/16.3

             The required entry in the kernel config file is:

                   options TEL_S0_16_3

             The required entry in device.hints(5) file is:

                   hint.isic.0.at="isa"
                   hint.isic.0.port="0xd80"
                   hint.isic.0.irq="5"
                   hint.isic.0.flags="3"

             This card is completely i/o mapped and must not have an maddr
             statement in the hints file.

             Valid interrupts (hint.isic.N.irq) are 2, 5, 9, 10, 12 or 15.

             These boards have a jumper which specifies an i/o base address
             (hint.isic.N.port) of either 0xd80, 0xe80 or 0xf80.

             Notice: Although the switch positions are labeled 0x180, 0x280
             and 0x380, the card is to be configured at 0xd80, 0xe80 or 0xf80
             respectively!

     AVM A1 and AVM Fritz!Card

             The required entry in the kernel config file is:

                   options AVM_A1

             The required entry in device.hints(5) file is:

                   hint.isic.0.at="isa"
                   hint.isic.0.port="0x340"
                   hint.isic.0.irq="5"
                   hint.isic.0.flags="4"

             These boards have a jumper which specifies an i/o base address
             (hint.isic.N.port) of either 0x200, 0x240, 0x300 or 0x340.

             Valid interrupt (hint.isic.N.irq) values are 3, 4, 5, 6, 7, 10,
             11, 12 or 15.

             Older Versions of the AVM A1 also require setting of an IRQ
             jumper, newer versions of this and the Fritz!Card only have an
             i/o base jumper and the interrupt is setup at runtime by
             reprogramming a register.

             14, 15.

             Notice: this card has a strange address decoding scheme resulting

             address range.

CAVEATS

     Note that all of ISA boards with i/o ports actually use several ranges of
     port addresses; Teles happen to refer to the 0xd80 range in their
     documentation (the board also uses 0x180 etc.), while AVM happen to refer
     to the 0x200 range in their documentation (the board also uses 0x600
     etc.)  The driver matches the manufacturers’ description for the purposes
     of configuration, but of course makes use of all the ports in order to
     operate the card.

AUTHORS

     The isic driver and this manpage were written by Hellmuth Michaelis
     〈hm@FreeBSD.org〉.  It is based on earlier work of Arne Helme, Andrew
     Gordon and Gary Jennejohn 〈gj@FreeBSD.org〉.

BUGS

     Since there is no hardware documentation available from the manufacturers
     of several boards, it is likely that there are many bugs left.
