A System and Method for Managing the Signaling Control Channel and Transferring Service Entity Information using the In-Fiber Signaling Control Channel in O-UNI between Client and Optical Transfer Network

摘要

PURPOSE: A signaling control channel management by using In-Fiber signaling control channel in an O-UNI between a client and an optical transmission network and a service shape information transmission system and a method therefor are provided to identify the connection of the traffic channel through a process for identifying the connection of signaling control channel. CONSTITUTION: A signaling control channel management by using In-Fiber signaling control channel in an O-UNI between a client(100) and an optical transmission network and a service shape information transmission system includes a client(100) and an optical transmission network(200). The client(100) includes a user USONET/SDH/WDM processing block(15) and a link managing block(12). The user USONET/SDH/WDM processing block(15) is connected to the optical transmission network(200) through the physical link for managing the traffic channel. The link managing block(12) identifies the connection of the signaling control channel to the optical transmission network(200) by using a predetermined In-Fiber signaling control channel and manages the status of the signaling control channel. And, the optical transmission network(200) includes an optical transmission network NSONET/SDH/WDM processing block(25) and an optical transmission link managing block(22). The optical transmission network NSONET/SDH/WDM processing block(25) is connected to the user USONET/SDH/WDM processing block(15) and the physical link for managing the traffic channel. And, the optical transmission link managing block(22) identifies the signaling control channel connection to the client(100) by using the In-Fiber signaling control channel to manage the status of the signaling control channel.
