Siemens S30813-Q24-X-2/01 EWSD digital switching exchange Telecom System Card / Module

The Siemens S30813-Q24-X-2/01 is a circuit board for the EWSD digital switching exchange. EWSD (Elektronisches Wahlsystem Digital) is Siemens’ large central-office switching system, built from plug-in boards that sit in racks and shelves for the line units, the switching network, the coordination processor and the peripheral modules. Siemens developed it from the late 1970s and kept supporting it through Siemens Networks and Nokia Siemens Networks, and exchanges built on it are still running in fixed-line networks in many countries. The board is identified by its Siemens material code, S30813-Q24-X-2/01. Boards with the same base code can differ by revision suffix, and the right one depends on the software release and hardware generation of the installation, so quote the full code from your existing board. Tech-Star (UK-based, shipped worldwide) stocks EWSD spares for network operators and maintenance engineers looking after legacy exchanges.
