MSTP equipment TDM plane can support 1588V2

On the U2000 network management, the packet plane and TDM plane in the Hybrid MSTP device can be managed uniformly to achieve end-to-end service intercommunication.

An intelligent clock subnet can realize the automatic tracking and automatic switching of the clock only by configuring the reference clock, avoiding the clock interlock.

Network elements A, B, and C are OSN 3500 forming a chain network. The two stations A and C are connected to routers. The IP routers are connected to the OptiX SDH equipment through the POS port of STM-1. The PAS port connects J1 and C2 bytes. It is also used as a payload to transfer bytes (used to carry services). The network element A to the network element C creates a VC4 service, and the network element B uses VC4 to pass through.
In this case, is there an alarm report inside the SDH network?

If the OSN6800 device wants to achieve 1588V2 time synchronization, it must be configured with an electrical crossover board
