Glossary B

B-ICI SAAL

B-ICI Signaling ATM Adaptation Layer: A signaling layer that permits the transfer of connection control signaling and ensures reliable delivery of the protocol message. The SAAL is divided into a Service Specific part and a Common part (AAL5).

BIP

Bit Interleaved Parity: A method used at the PHY layer to monitor the error performance of the link. A check bit or word is sent in the link overhead covering the previous block or frame. Bit errors in the payload will be detected and may be reported as maintenance information.

BIS

Border Intermediate System.

B-ISDN

Broadband ISDN: A high-speed network standard (above 1.544 Mbps) that evolved Narrowband ISDN with existing and new services with voice, data and video in the same network.

BISUP

Broadband ISDN User's Part: A SS7 protocol which defines the signaling messages to control connections and services.

B-LLI

Broadband Low Layer Information: This is a Q.2931 information element that identifies a layer 2 and a layer 3 protocol used by the application.

BMT

Basic Mode Transmission

BN

Bridge Number: A locally administered bridge ID used in Source Route Bridging to uniquely identify a route between two LANs.

BN

BECN Cell: A Resource Management (RM) cell type indicator. A Backwards Explicit Congestion Notification (BECN) RM-cell may be generated by the network or the destination. To do so, BN=1 is set, to indicate the cell is not source- generated, and DIR=1 to indicate the backward flow. Source generated RM-cells are initialized with BN=0.
