CPM (Central Processor Module) The CPM module is equipped standard in KSU1. This board contains all circuitry required to control the fully equipped DX-80. The system uses the CPM to perform all digital voice switching and call processing data switching. The CPM has one ribbon cable connector for connection to the KSU1 408M and five (5) connector sockets for connection of the system built-in modem, voice processor, and second cabinet (KSU2). Since the CPM comes installed inside of KSU1 the CPM ribbon cable is already in place and connected to the KSU1-408M J5 socket. Assuming the orientation of the KSU1 cabinet is installed on the wall; the two horizontal connector sockets in the upper right corner of the CPM are for the MDM (Modem Module). The connector socket labeled “2nd Cabinet” is for connection to the KSU2-408E if that expansion is required. The remaining two connector sockets on the CPM, one at the left side, the other at the right side are for the voice processor solution. Note: The voice processor solution can be any of three possible choices: AAM, 7271C, or 7270C.
