BRI
From BRIstuff.org
BRI is Basic Rate Intarfece ISDN. It uses 2 64kbps "bearer" (B) channels and 1 16kbps "data" (D) channel. The D channel is actually a control channel and the B channels are used to transmit voice, data or whatever.
BRIstuff adds support for ISDN BRI to libpri and Asterisk, that only supported PRI ISDN (E1, T1). It also includes Zaptel drivers for several ISDN BRI adapters (HFC-s - based PCI cards and the Junghanns dual, quad and octo BRI cards). Drivers for he Xorcom Astribank BRI module are already included in Zaptel.
