OverviewR-STM-1E is a multiplexer based on Synchronous Digital Hierarchy (SDH) transmission cores for the Local Loop, supporting up to 63 E1s or a mix of E1/E3 or E1/T3 tributary interfaces.The unit can be deployed in access nodes as a terminal multiplexer (TM) or add-drop multiplexer (ADM). It enables expansion of the Local Loop to 60 km (37 miles), creating a transmission layer fully compatible with regional and national SDH networks. From this transmission layer, the full range of multiservice access solutions can be deployed to provide cost-effective and quick service deployment.SDH transmission supports a full range of access systems, including Remote Subscriber Units (RSUs), Digital Line Carriers (DLCs), digital cross connect (DXC 1/0) and service multiplexers.
