Versatile-ISDN (vISDN for short) is yet another
ISDN implementation for Linux. It aims at being an
open, modular, flexible, and versatile
architecture to connect Linux to the ISDN. vISDN
is comprised of a channel crossconnector, a
lapd/q.931 implementation, an Asterisk channel
driver, PPP networking, traffic analysis through
Ethereal, and much more. vISDN is in the process
of obtaining a certification of compliance from an
independent lab. vISDN currently supports Cologne
Chip's HFC-based cards for either BRIs and PRIs in
user-role or network-role.
