AAL
ATM Adaptation Layer

Provides a conversion function to and from ATM (Asynchronous Transfer Mode) for various types of information, including voice, video, and data. There are several versions of AAL, each applicable to a given information type. All of them convert elements of an information stream (such as voice frames and data packets) into cells, giving ATM the versatility to carry many different types of data, from constant rate voice data to highly bursty messages generated by LAN (Local Area Network), all within the same cell format.
