Siemens S30810-Q887-X102-2/01 EWSD digital switching system Telecom System Card / Module

The Siemens S30810-Q887-X102-2/01 is a card from the Siemens EWSD (Elektronisches Wahlsystem Digital) digital switching platform, identified in Siemens documentation and specialist telecom parts catalogues by the internal module code CCGB. EWSD was Siemens’ long-running electronic telephone exchange system, deployed worldwide in fixed-line switching centres, with subscriber, line, processor and maintenance functions spread across a large family of plug-in cards such as this one. As is common with legacy Siemens exchange hardware, the precise onboard function of the CCGB module is not independently documented in publicly available sources; what is well established, corroborated by multiple specialist telecom equipment resellers explicitly listing it under the EWSD platform, is its identity as a genuine EWSD-family card. This is refurbished or used legacy telecom hardware, supplied as-is for maintenance, expansion or spares purposes on exchanges still running Siemens EWSD infrastructure. Tech-Star (UK-based, shipped worldwide) can source and test this exact part on request. Get in touch with your requirement and we will confirm current stock and condition.
