  • Page 28: Constraints

    1.2.5 Constraints Certain I/O cards cannot coexist in the same CX950 chassis due to the use o faster DSPs (Digital Signaling Processors). A C.54 DSP is used on the DAV I/O card, the BRI-DV I/O card, the DIM I/O card. These cards therefore cannot be used in the same chassis as the DDVC card (which must be used with the ISDN S/T I/O Card) and the Analog Voice I/O card, which use a C.31 DSP.
