WebApr 3, 2024 · ATM Adaptation Layer (AAL) • AAL is responsible for adaptation of information of higher layers to the ATM cells (in the transmission direction) or adaptation of ATM cells into the information of the higher layer (receiver direction). • AAL is subdivided into two sublayers: - SAR (Segmentation and Reassembly) - CS (Convergence … WebA Signalling ATM Adaptation Layer (SAAL) resides between the ATM layer and Q.2931. The purpose of the SAAL is to provide reliable transport of Q.2931 messages between peer Q.2931 entities (e.g., ATM Switch and host) over the ATM layer. The SAAL is composed of two sublayers, a common part and a service specific part. ...
