ISDN BRI
An ISDN Basic Rate Interface (ISDN BRI) is a type of ISDN interfaces that uses two B channels for user data, and one 16-kbps D channel for ISDN D-channel signalling. Both B channels can be switched; both channels can be nailed up; or one channel can be switched and the other nailed up. A line of this type can connect to standard voice service, Switched-56 data service, or Switched-64 data service.
