DESCRIPTION
 The 
iavc driver is used to glue the AVM family of active cards to the 
isdncapi(4) driver and the 
isdn4bsd package. Currently only the AVM B1 PCI is supported. Support for the AVM B1 ISA and the AVM T1 PCI cards should be quite easy to add, since support already exists in the 
FreeBSD version of the driver.
To use this driver, you must first fetch the firmware file b1.t4 from ftp://ftp.avm.de/ and load it to the card using isdnd(8).
