Short description Together, SDH and SONET ensure standards so that digital networks can interconnect internationally and that existing conventional transmission systems can take advantage of optical media through tributary attachments. This practical guide explores the extensions to the SDH/SONET standards, which provide more granularity to transport bit rates used by data signals. Current hot topics are also discussed including contiguous concatenation and virtual concatenation.
