AAL2: ATM Adaptation Layer Type 2
ATM Adaptation Layer Type 2 (AAL2) is designed for variable bit rate video transfer. AAL2 is perfect for low-rate voice traffic, with compression, silent and idle channel suppression. AAL type 2 is subdivided into the Common Part Sublayer (CPS ) and the Service Specific Convergence Sublayer (SSCS ).
