Genuine Siemens M:MCLK master clock card, Siemens BS-240/241 BSC/Transcoder subrack platform. Tested legacy spare from Tech-Star.

The Siemens M:MCLK is a plug-in subrack card from the Siemens BS-240/241 BSC/Transcoder platform. The MCLK designation is consistent with a master clock or timing-reference function, providing the synchronisation signal that other cards in a Siemens BSC/Transcoder subrack rely on, though the precise internal function is not independently documented beyond its confirmed platform placement. Reseller and parts-catalogue listings place this part number within the S30861-Q331 family of BSC/Transcoder subrack modules. Master clock cards are critical to maintaining timing accuracy across a legacy Siemens 2G GSM base station controller and transcoder subrack, and are commonly stocked as maintenance spares. Tech-Star (UK-based, shipped worldwide) supplies tested legacy Siemens telecom cards. Contact us to confirm current stock and compatibility for your project.
