SDH Ring

An STM-1/OC-3 (SDH) ring is used to distribute high bandwidth among several buildings in a business park or campus environment. Add-drop multiplexing at the SDH node is performed by RAD's FCD-155E next generation SDH / SONET add/drop multiplexer. The FCD-155E provides a flexible user interface configuration for up to 21 E1 or 28 T1 lines, as well as Fast Ethernet or Gigabit Ethernet links. Such a large number of links enables a single device to provide E1/T1 services to multiple buildings. The FCD-155E can also provide ADM capabilities and service multiplexing based Fractional E1 services. In addition to the FCD-155E, RAD provides a complete solution, including the Megaplex access multiplexer, DXC cross connector, FCD access units, and ASMi-52 modem. The RADview-HPOV/TDM or RADview-PC/TDM network applications provide complete management to the entire network, including the customer-located equipment.
