Siemens S30807-Q6949-X10 telecommunications hardware (Hicom/HiPath/OpenScape PBX, SDH transmission) PBX Card / Module

The Siemens S30807-Q6949-X10 is an OCCB1 DSP expansion board for the OpenScape Business X3R, X3W, X5R, X5W and X8 systems, the single-DSP variant in the same OCCB family as the three-DSP OCCB3 card (S30807-Q6949-X). Like its sibling, OCCB1 adds extra digital signal processor channels to the system’s control unit, giving it more simultaneous voice-processing capacity for calls, conferencing or transcoding than the unexpanded board provides, but at a lower capacity increment than the OCCB3 variant, making it the right choice for sites that need a modest DSP uplift rather than the larger jump. It fits the same control-unit expansion slot as OCCB3 and is not a peripheral line or trunk card, so its loss affects processing headroom rather than a specific extension or route. Genuine Siemens OpenScape Business boards of this kind remain a routine requirement for operators sizing DSP capacity to their site’s call volume. Confirm exact model compatibility before ordering.
