Abstract
The invention relates to a method and circuit arrangement for the realization of the Higher Path Adaptation (HPA) function in Synchronous Digital Hierarchy (SDH) equipment. Such function serves to equalize frequency difference between the synchronisms of signals coming from different nodes of the network. The equalization is carried out through the use of the positive and negative justification technique. The invention, through the alteration of the justification instants, is capable of reducing the capacity of the elastic storage and the generated wander.
