http://www.fctele.com/news/what-are-pdh-sdh-difference-between-pdh-sdh/ The plesiochronous digital hierarchy (PDH) is a technology used in telecommunications networks to transport large quantities of data over digital transport equipment such as fibre optic and microwave radio systems. The term plesiochronous is derived from Greek plēsios, meaning near, and chronos, time, and refers to the fact that PDH networks run in a state where different parts of the network are nearly, but not quite perfectly, synchronized.

WebbThe TDM transmission SDH/SONET basically makes a high precision synchronous network with a unique high-quality clock, from this bit clock it creates a digital hierarchy, with high-order multiplex when crossing large node and inside the node it generates low-order multiplex with sub-rate transmission (TU) and Virtual Containers (VC) of usable data … WebbFor transmission network synchronization (SDH), a plan must be developed with a special sync planning tool. In ITU-Recommendation G.811 (Timing Characteristics of Primary Reference Clocks) a network clock stability of 1 x 10 E-11 for the Primary Reference Clock (RPC) is recommended.
