Bearer Capability Class (BCC)
A code that identifies the type of a call, such as a voice call and different types of data calls. Determination of BCC is
based on the characteristics of the caller for non-ISDN endpoints, and on the Bearer Capability and Low-Layer
Compatibility Information Elements of an ISDN endpoint. Current BCCs are 0 (voice-grade data and voice), 1 (DMI
mode 1, 56-kbps data transmission), 2 (DMI mode 2, synchronous or asynchronous data transmission up to 19.2 kbps), 3
(DMI mode 3, 64-kbps circuit/packet data transmission), 4 (DMI mode 0, 64-kbps synchronous data), 5 (temporary
signaling connection), and 6 (wideband call, 128 kbps to 1984 kbps synchronous data).

Bipolar Eight Zero Substitution (B8ZS)
A line-coding technique that is used in North American T1 circuits and ISDN-PRI circuits. To guarantee ones density,
B8ZS removes an octet of all zeros, and replaces the octet with a pattern that contains bipolar line violations in specific
bit locations. A B8ZS receiver removes the octet with the substituted pattern, and replaces that octet with the original
octet of all zeros.
bit error rate (BER)
The percentage of bits that are received in error compared to the number of bits that are sent.
bit rate
The speed at which bits are transmitted, which is usually expressed in bits per second. The bit rate depends on the speed
of the transmission, and thus is not the same as the actual capacity of the channel. Also called data rate and data
signaling rate.

bridge
A device that is generally used to connect segments of a local area network (LAN) to other LAN segments or to a wide
area network (WAN). A bridge routes traffic on the Level 2 LAN protocol (for example, the Media Access Control
address), which occupies the lower sublayer of the LAN Open Systems Interconnect (OSI) data link layer. A bridge can
be equipped to provide frame relay support to the LAN devices that the bridge serves. A bridge that provides frame relay
support encapsulates LAN frames in frame relay frames. The bridge then feeds those frame relay frames to a frame relay
switch for transmission across the network. A bridge that provides frame relay support also receives frame relay frames
from the network, strips the frame relay frame off each LAN frame, and passes the LAN frame on to the end device. See
