Samsung KP0S74B0AS XAR(J) OfficeServ OAS Card 7000 Series

The Samsung OfficeServ OAS Card KP0S74B0AS (also listed as KP-OS74BOAS/XAR) is an optional Application Services module for the OfficeServ 7000-series telephone systems, adding on-board processing capability with 64 DSPs. Those DSPs can be configured as MGI channels, MOBEX DTMF receivers used by the Executive MOBEX feature, or a mix of both, enabling DSP-based OfficeServ applications without consuming the system’s main processors. In cabinet terms, MOBEX and related DSP services require the OAS card on OfficeServ OS7200-S and OS7400, while OS7030 and OS7100 configurations can operate MOBEX without the OAS hardware in many setups; the OAS option specifically expands capacity for larger 7000-series deployments. This card is documented as a 64-DSP option that augments the 7000-series system’s ability to run application services, with compatibility across OS7030, OS7100, OS7200-S, and OS7400 configurations when the OAS card is installed.
