Siemens S30807-Q6949-X telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) PBX Card / Module

The Siemens S30807-Q6949-X is an OCCB3 DSP expansion board for the OpenScape Business X3R, X3W, X5R, X5W and X8 systems. OCCB boards add extra digital signal processor channels to the system’s control unit, and the ‘3’ in OCCB3 denotes the three-DSP variant, giving the system more simultaneous voice-processing and conferencing/transcoding capacity than the base board provides on its own. It sits alongside the sibling OCCB1 (single-DSP) card in the same family, with the choice between them driven purely by how much extra DSP capacity a given site’s call volume and feature set needs. As a control-unit expansion board rather than a peripheral line card, its loss reduces the system’s processing headroom rather than taking any specific extension or trunk out of service. Genuine Siemens OpenScape Business boards of this kind remain a routine requirement for operators expanding or restoring DSP capacity on established installs. Confirm exact model compatibility against your system’s control unit before ordering. Tech-Star is UK-based and ships worldwide; contact our sales team for current stock and pricing.
