Broadband ISDN - ATM Adaptation Layer for Constant Bit Rate Services Functionality and Specification
This standard is one of a series of American National Standards on Broadband Integrated Services Digital Network (B-ISDN). These standards describe the B-ISDN capabilities, architectural model, and network interfaces including protocol functionalities and specifications, and signaling characteristics. This standard describes the protocol of the ATM Adaptation Layer for Constant Bit Rate Services (CBR AAL). The ATM Adaptation Layer (AAL) performs the necessary functions to match the services provided by the ATM Layer to the services required by the AAL service user. It provides to its users services that are not available from the ATM Layer. This document concentrates on the ATM Adaptation Layer for Constant Bit Rate Services.
