Version 1.5.0
=============

List of new features currently not found in I4B:
================================================

	- driver use a mutex to protect data and chip access
	- direct access to D-channel and B-channel
	- full support for NT-mode in software and hardware
	  NOTE: not all hardware can run NT-mode
	- new ``isdnphone'' that uses a kernel soundbridge
	- new ``isdnd'' 
	- USB support

About the driver:
=================

This driver should work with the FreeBSD-5-current sources from 1st of
April 2004 or later. Using this driver with earlier FreeBSD-5-current
sources may also work. The driver supports generic IPAC / ISAC / HSCX
/ HFC / WINBOND chips and allows the drivers to emulate behind one or
more of those chips. As a consequence of this any ring-buffer or
block-buffer ISDN device can easily be implemented with a minimum of
code. To have more people being able to test the driver there has been
added support for some cards already found in ISDN4BSD.  Please see
the ``new_ihfc'' manual.

NOTE: Please send patches using `diff -crN` and include the complete file if 
the patch is big. 

NOTE: this driver use an older version of the USB-controller driver,
because the existing USB-controller driver have some problems with
isochronous pipes: It does not recover from data-underflow or
data-overflow. The USB-controller driver needs to be re-written! The
USB-controller interface should also be re-written.

NOTE: macros can be expanded with ``cpp -I/sys''

Changes since last version:
===========================

	- TELEINT ISDN SPEED fixed 
	- fixed a bug in the WIBPCI driver
	- code cleanup
	- support for HFC-S USB added (NOTE: USB is only supported with UHCI USB controllers, because the isochronous-pipe support is not finished with the other USB-drivers)

To use NT-mode you need to add the following lines to the ``SYSTEM
section'' in the file ``/etc/isdn/isdnd.rc'':

controller # 0
driver_type = DRVR_DSS1_NT
controller # 1
controller # 2
controller # n

To use isdnphone you need to add the following lines to ``/etc/isdn/isdnd.rc'':
