NAME

     isdn -- ISDN kernel to userland master device

SYNOPSIS

     pseudo-device isdn

DESCRIPTION

     The isdn device driver is used by the isdnd(8) daemon to exchange messages with the ISDN kernel part for the purpose of call establishment,
     control and disconnection and to access various control and status information.

     The messages and message parameters are documented in the include file /usr/include/netisdn/i4b_ioctl.h.

     The available ioctl's are:

	   I4B_CDID_REQ
		   Request a unique Call Description IDentifier (cdid) which identifies uniquely a single interaction of the local D channel with
		   the exchange.
	   I4B_CONNECT_REQ
		   Actively request a call setup to a remote ISDN subscriber.
	   I4B_CONNECT_RESP
		   Respond to an incoming call, either accept, reject or ignore it.
	   I4B_DISCONNECT_REQ
		   Actively terminate a connection.
	   I4B_CTRL_INFO_REQ
		   Request information about an installed ISDN controller card.
	   I4B_DIALOUT_RESP
		   Give information about call setup to driver who requested dialing out.
	   I4B_TIMEOUT_UPD
		   Update the kernels timeout value(s) in case of dynamically calculated shorthold mode timing changes.
	   I4B_UPDOWN_IND
		   Inform the kernel userland drivers about interface soft up/down status changes.
	   I4B_CTRL_DOWNLOAD
		   Download firmware to active card(s).
	   I4B_ACTIVE_DIAGNOSTIC
		   Return diagnostic information from active cards.

     Status and event messages available from the kernel are:

	   MSG_CONNECT_IND
		   An incoming call from a remote ISDN user is indicated.
	   MSG_CONNECT_ACTIVE_IND
		   After an incoming call has been accepted locally or an outgoing call has been accepted by a remote, the exchange signaled an
		   active connection and the corresponding B-channel is switched through.
	   MSG_DISCONNECT_IND
		   A call was terminated.
	   MSG_DIALOUT_IND
		   A userland interface driver requests the daemon to dial out (typically a network interface when a packet arrives in its send
		   queue).
	   MSG_IDLE_TIMEOUT_IND
		   A call was terminated by the isdn4bsd kernel driver because a B-channel idle timeout occurred.
	   MSG_ACCT_IND
		   Accounting information from a network driver.
	   MSG_CHARGING_IND
		   Charging information from the kernel.

NAME

     daic -- isdn4bsd driver for EICON.Diehl active ISDN cards

SYNOPSIS

     daic0 at isa? iomem 0xd8000 irq 10

DESCRIPTION

     The daic driver supports the old Diehl active cards: S, SX, SXn, SCOM and QUADRO.

     For a QUADRO card, the driver will detect the board type and use all four ports, each attached as a controller of its own to the isdn4bsd
     system, which can be listed using the daicctl utility.

     The daic driver interfaces the ISDN card to the ISDN4BSD kernel subsystem.  All lower layer ISDN control is handled by the card. This should
     allow you to run any national ISDN protocol delivered by EICON.Diehl for your card, but the driver has only been tested with the DSS1 proto-
     col and some parts of the cards interface are ISDN protocol dependent.

     The daic driver is written to conform to the software interface documented by Diehl in their ISDN-Karten Benutzerhandbuch from 1992.

MICROCODE DOWNLOAD

     Every active card needs its own operating software before it can work. You have to download this to the card before using it with isdn4bsd.
     Use the daicctl utility to do this, i.e. call daicctl -d te_etsi.sx 1 to download the file te_etsi.sx to controller number 1. Use daicctl -l
     to list all available controllers (and ports). You have to select the correct ISDN protocol file for your ISDN interface, see the Diehl docu-
     mentation for details.

     The cards bootstrap process involves another file, which is independent of the card type you use and the protocol you run. It is called
     download.bin in current versions of the Diehl software distribution and has to be copied to the kernel compile directory under
     dev/microcode/daic and converted into a header file used when compiling the kernel by running make in that directory. Your kernel compile
     will fail and remind you of this if you forget to do this. Due to copyright restrictions we cannot distribute the driver with this file inte-
     grated. But if you own a card, you do have the file (or can get it from the Diehl web server).
