Sdh overhead
WebbSDH monitoring functions are implemented using overhead bytes. SDH provides monitoring at section and channel levels. Sections are subdivided into regenerator and multiplex sections. Channels are subdivided into higher-order and lower-order paths. Webb• Multiplex Section Overhead – The Multiplex Section Overhead contains the information required between the multiplexer section termination equipment at each end of the Multiplex section. – The Multiplex Section Overhead is found in Rows 5 to 9 of Columns 1 through 9 x N of the STM-N, N ≥1 frame. • Path Overhead – Discussed earlier ...
