Multi-Service SDH Transmission System (RS1010)

Overview

RS1010 is the STM-1 level multi-service 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 flexible multi-service platform. With optional cards such as E1 card, Ethernet card and Engineering Order Wire card (EOW), it is easy to meet user’s various requirements. It provides fully cross connectivity between all tributaries, and can be used as a Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.
