Siemens S32011-Q111-B803-1 telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) Optical Transmission Module

The Siemens S32011-Q111-B803-1 belongs to the TransXpress S32011 line equipment numbering, which is confirmed by the prefix, but the Q111 group within that range is not described in any published listing we could rely on. Other groups in the same block are documented as optical interfaces, controllers and telemetry cards, and we are not going to assign this one to any of them on the strength of a pattern. The board itself carries a legend and we will read it for you.

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.
