Siemens IOC:CPI EWSD (Elektronisches Waehl System Digital) digital switching exchange Telecom System Card / Module

The Siemens IOC:CPI (internal material code S30810-Q782-X-10/01) is a subrack card from the Siemens EWSD (Elektronisches Waehl System Digital) digital switching exchange platform. Siemens EWSD (Elektronisches Waehl System Digital) is a large-scale digital switching exchange system widely deployed by network operators for public telephone network switching, while the BS-240/241 range covers Siemens’ GSM base transceiver station, base station controller and transcoder equipment. This card is identified by the board designation “IOC:CPI” in Siemens’ internal parts records and forms part of a large family of subrack-mounted interface, processor and control cards used across EWSD digital switching exchange installations. The card’s specific function within the subrack has not been independently confirmed from available documentation, so it is offered here as an identified EWSD digital switching exchange spare/replacement card rather than with a claimed precise role. Tech-Star (UK-based, shipped worldwide) stocks used and refurbished legacy Siemens telecom exchange hardware including this card.
