Abstract :
ATM Adaptation Layer type 1 (AAL1) that can be divided into the Convergence Sublayer (CS) and Segmentation and Reassembly (SAR) sublayers is designed to provide the class A traffic of ATM layer. The AAL1 SAR Protocol Data Unit (PDU) header uses Cyclic Redundancy Check (CRC) and even parity to detect and correct errors. After describing the encoding rules of the CRC and parity-check, this paper carefully analyzes the process of correcting a single-bit error and detecting multi-bit errors in the AAL1 SAR-PDU header.
