    Global Tech GT-SDH-155A 63E1 SDH is the compact STM-1 level Synchronous Digital Hierarchy (SDH) transmission system compatible with ITU-T standard. It is designed as a modular system with two 155.520Mb/s optical interfaces to provide an ultra-compact, cost-effective and high capacity platform. It provides fully cross-connect between all tributaries, and can be used as Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.
