Actual Allocated Capacity

AAL

ATM Adaptation Layer: The standards layer that allows multiple applications to have data converted to and from the ATM cell. A protocol used that translates higher layer services into the size and format of an ATM cell.

AAL Connection

Association established by the AAL between two or more next higher layer entities.

AAL-1

ATM Adaptation Layer Type 1: AAL functions in support of constant bit rate, time- dependent traffic such as voice and video.

AAL-2

ATM Adaptation Layer Type 2: This AAL is still undefined by the International

Standards bodies. It is a placeholder for variable bit rate video transmission.

AAL-3/4

ATM Adaptation Layer Type 3/4: AAL functions in support of variable bit rate, delay-tolerant data traffic requiring some sequencing and/or error detection support. Originally two AAL types, i.e. connection-oriented and connectionless, which have been combined.
