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.
