ALCATEL 3BW12793AA 1000 E10 TABASH Telecom System Card / Module

The Alcatel 3BW12793AA is a TABASH board for the Alcatel 1000 E10 (OCB-283) digital switching exchange, a multipurpose telephone exchange platform used for local and transit switching applications, signalling transfer point (STP) functions and mobile service switching point (MSC) duties across legacy PSTN and early mobile core networks. The exact part number 3BW12793AA is directly documented against the TABASH board designation in Alcatel 1000 E10 exchange parts references, confirming this unit’s identity and platform. As with other internal exchange boards in the E10/OCB-283 family, TABASH sits within one of the exchange’s functional subsystems, working alongside sibling interface, control and matrix boards within the same equipment bay to deliver the specific switching or signalling function its designation covers. The Alcatel 1000 E10 was deployed extensively across PSTN, STP and early GSM/MSC core networks internationally, and tested pulls of exchange boards like this remain in demand for maintaining legacy installations still in service or for spares provisioning where new-build hardware is no longer manufactured.
