What is SDH and PDH Framing Overview about?

The document describes the framing structure of Synchronous Digital Hierarchy (SDH) networks. SDH uses Transport Units (TUs) that contain overhead and payload data and are grouped into higher order TUs. The basic TU is TU-12, which can be concatenated to form VC-4, STM-1, and higher order structures with additional overhead and pointers to direct the payload within.
