Abstract :
The scope of CCITT (International Consultive Committee for Telephone and Telegraphy) Recommendations on which significant progress has been made is reviewed. These consist of Recommendations G.781, 782, and 783, dealing with synchronous multiplexers; Recommendation G.784, dealing with synchronous digital hierarchy (SDH) management; Recommendation G.958, concerning digital line systems based on the SDH for use on optical fiber cables; Recommendation G.957, dealing with optical interfaces; and Recommendations G.sna1 and 2, concerning network aspects of SDH.<>
