Broadband ISDN is a standard for transmitting voice, video and data at the same time over fiber optic telephone lines. It can support data rates of 1.5 megabits per second (Mbps), but it has not been widely implemented because not a lot of areas are wired to fiber optic.

Broadband ISDN is an ISDN Primary Rate Interface (PRI) line. This type of line is primarily used for businesses because it is comprised of 23 data channels and is much more expensive than the 2-channel Basic Rate Interface (BRI) ISDN line installed in the typical user's home.
