As an OSC board, the AST2 board processes two channels of supervisory signals in opposite directions, transmits and extracts the overhead information about the system, processes and sends the overhead information to the SCC. In addition, the AST2 board can process the IEEE 1588v2 protocol for time synchronization. The AST2 board also supports transparent transmission of two channels of FE electrical signals and line fiber quality monitoring
Initial Version:
8800 V100R011C00
9800 V100R002C10SPC300
Application
SCC <------>AST2 <------> FIU/SFIU
Note:
When the AST2 board works with the SFIU board, the signal wavelengths of supervisory channel for RM1 is 1511 nm, and the signal wavelengths of supervisory channel for RM2 is 1491 nm. In this application scenario, the functional version of the FIU board must be TN13FIU03 or TN16FIU01, and the functional version of the SFIU board must be TN11SFIU01.
The TN11AST2 board can only interwork with a TN11AST2 board for OSC interconnection.
