TN11AST2

Huawei OSN6800, OSN8800 TN11AST2, Bidirectional optical supervisory channel and timing transmission unit (with Advanced OTDR).

The available functional version of the AST2 board is: TN11.

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.

The AST2 board is mainly used to process and regenerate optical supervisory signals. In addition, the AST2 board supports the IEEE 1588v2 function. In addition, the AST2 board supports 1588v2 and line fiber quality monitoring.
