SDH Integration of TDM Signals
The Synchronous Digital Hierarchy (SDH) has evolved as a result of standardization proposals in the International Telecommunications Union—Telecommunications Services Sector (ITU—TS) for an international optical interface standard for carriers and features for improved network management. The SDH format allows different types of signal formats to be transmitted over the fiber-optic cable. It allows adding or dropping signals within a single multiplexer. Communication between various localized networks is complex due to differences in digital signal hierarchies, encoding techniques, and multiplexing strategies. Communications between time-division multiplexed (TDM) networks previously described require complicated ...
