Siemens S30813-Q100-X303-7, EWSD board.

The Siemens S30813-Q100-X303-7 is a circuit board for the EWSD digital switching exchange. EWSD (Elektronisches Waehlsystem Digital) is Siemens’ large central-office switching system, built around a central coordination processor with peripheral units that carry the lines and trunks. Siemens stopped selling it in 2017, but many operator exchanges are still in service. The Siemens material code identifies the exact board variant within the EWSD card family, and it is matched to its shelf position rather than swapped freely between board types. Tech-Star (UK-based, shipped worldwide) stocks Siemens EWSD spares for operators keeping these exchanges running. Send us the shelf and slot details and we will help match the right board.
