virtual container (SDH) (VC-n)

A virtual container( VC) is a data frame in the Synchronous Digital Hierarchy( SDH) that consists of the container with overhead. This can be the Section Overhead( SOH) or the Path Overhead( POH).

A virtual container supports the connection between different Path Layers and handles the end-to-end transport of the data. Virtual containers consist of the Path Overhead (POH) and the Payload Container and are passed through at network nodes. The Path Overhead is essentially static and repeats in each STM frame with the same content. Exceptions are the Path Traces and Section Traces and the Bit Error Counter. These signals together form the virtual container (VC).
