OTN Overheads
- OTN Overheads
The optical transport network (OTN) is a new optical transport hierarchy defined in ITU-T G.872, G.798 and G.709, which consists of an optical layer and an electrical layer. In addition, the electrical layer and optical layer have a corresponding management and monitoring mechanism and survivability mechanism.
- Availability
This section provides the information about the equipment that support the OTN overhead management and configuration.
- Function Implementation
The OTN standard system has defined all kinds of overhead bytes. This enables the OTN network to have the following advantages: effective monitoring function, flexible grooming capability at both the optical and electrical layers, and carrier-class, manageable, and operable network. The OTN processing module inside the board processes the OTN overheads and thus help the equipment monitor signals and report the performance events of the signals.
- Application of the OTN Overhead
This section describes the application scenarios of the OTN overhead.
- Configuring OTN Overhead
This chapter describes how to configure the OTN overhead.
