LOGICAL MACHINE FOR PROCESSING CONTROL INFORMATION OF TELECOMMUNICATION TRANSMISSION FRAMES

摘要

A logical machine for processing Synchronous Transport Module (STM) frames STM-4c transmitted according to the Synchronous Digital Hierarchy (SDH) protocol. Each frame STM-4c carries data information and control information which includes a pointer information and concatenation informations. The pointer information indicates the start location of the data information in the frame and the concatenation informations indicate the structure of this data information. The logical machine is relatively simple since it operates according to a single state diagram in function of a single word comprising both the pointer information and the concatenation informations of a same frame.
