Application
As an OSC board, the ST2 board processes two OSC signals, east and west, extracts monitoring and management information from the two OSC signals, and sends the information to the SCC board for processing.In addition, the ST2 board can process the IEEE 1588v2 protocol for time synchronization. The ST2 board also supports transparent transmission of two channels of FE electrical signals.In addition, the TN12ST2 board supports line fiber quality monitoring.The TN13ST2 board supports the ITU-T G.8275.1 protocol.
Figure 1 and Figure 2 illustrate the position of the ST2 board in a WDM system.

Figure 2 Position of the TN12ST2 board in the WDM system
NOTE:
In this application scenario, the functional version of the FIU board must be 13FIU03 or 16FIU01, and the functional version of the SFIU board must be 11SFIU01.
When the ST2 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.
The 12ST2 board can only interwork with a 12ST2 board for OSC interconnection, and the 11ST2 board can interwork with a 13ST2 board for OSC interconnection.
Transmits and receives two OSC signals in two directions: west and east.
In a WDM network that uses the OSC channel for optical performance surveillance, NEs transmit monitoring and management information over the OSC channel. For a network shown in the figure above, the user can log in to NE1 through Ethernet to directly manage NE1. NE2 and NE3 are remote NEs and can be remotely managed through NE1 using the OSC channel. In this manner, the user can manage the entire network.
On NE1, the SCC board sends the local monitoring and management information to the ST2 board. The ST2 board converts the monitoring and management information into an OSC signal and sends the signal to the SFIU/FIU board. The SFIU/FIU board multiplexes the OSC and main channel signal onto the line for transmission.
On NE2, the SFIU/FIU boards demultiplex the OSC and main channel signals coming from the line and send the two OSC signals to the ST2 board. Then the ST2 board recovers the monitoring and management information from the two OSC signals and sends the information to the SCC board for processing.
On NE3, the OSC signal processing is similar to that on NE1.
The TN12ST2 board supports the line fiber quality monitoring function.
Performs IEEE 1588v2/ITU-T G.8275.1 clock synchronization.
Extracts clock signals and provides the clock signals for clock synchronization on an NE. The extracted clock signals can also function as a clock source for the clock board on this NE.
