Description

AN-MSSTS 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, Ethernet, V.35 and Engineering Order Wire card (EOW). It can be used as a Terminal Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to build point-to-point, ring and chain transmission network.
