TRANSFER SYSTEM IN ASYNCHRONOUS TRANSFER MODE

摘要

PURPOSE:To reduce a fault restoration time and to attain error correction and cell abort compensation with high reliability. CONSTITUTION:A virtual path VP1 is formed by adding control information based on an error correction code rule and a cell sequence number to each cell of input virtual line groups VC11-VC14 by a sender side virtual line switch VCH1, the virtual path is copied to generate a virtual path VP2 and the two virtual paths are connected to a receiver side virtual line switch VCH 2 via virtual line path cross connectors VPH1-VPH3 in a different route. The receiver side virtual line switch VCH2 applies buffering to cells of the virtual paths VP1,VP2 and implements cell abort compensation by a cell sequence number for error correction.
