Processor Description
DBS call-processing is controlled by the Call Processor Card (CPC). Four
CPC models are available: CPC-A, CPC-B, CPC-AII, and CPC-EX. For a
complete list of hardware enhancements available with the CPC-B, CPC-AII,
and CPC-EX, please see Appendix A and Appendix B, located in the back of
this manual. See the Appendix in Section 700 - Feature Operation for a
complete list of feature enhancements associated with each of these CPCs.
In most cases, the features provided with the DBS depend on the model and
software version of the CPC. However, the availability of some features also
depends on the model and version of the Service Circuit Card (SCC).
The following table shows some of the major differences between CPC/SCC
features. Other differences are noted throughout this manual when they apply
to specific installation instructions. For more details on the features provided
with each processor, see Feature Operation, Section 700.
