Siemens S32011-Q121-X201-51 telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) Optical Transmission Module

The Siemens S32011-Q121-X201-51 is a TransXpress SLD16 synchronous multiplexer controller from the X201 build group. Controllers of this type carry the terminal’s control processor, its timing reference handling and its management access, so an SLD16 shelf will not commission without one. Siemens issued several builds of the controller across the life of the platform and they follow the software release, which is why we ask which release you are running before matching a board.

The S32011 numbering belongs to Siemens TransXpress line equipment, the SLD16 and SLR16 family that carried STM-16 traffic on long haul and regional SDH routes before and through the Nokia Siemens Networks era. A terminal is assembled from optical interface units at STM-1, STM-4 and STM-16, a synchronous multiplexer controller, telemetry and supervisory interfaces, and the shelf power and control cards behind them. Inside the code the Q group marks the function and the tail marks the optical or build variant, so the whole string matters when you order.
