Cpm (Central Processor Module); Ksu1 Component) - Comdial DX-80 Installation & Maintenance Manual

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. All digital voice switching and call processing data switching is accomplished via the CPM.
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 2
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. (The voice processor solution can be any of three possible choices; AAM, FL-4 or PC-8.)
The CPM also provides the following standard connectors:
•
Music Channel 1 - On Hold/Background Music Interface
•
Music Channel 2 - On Hold/Background Music Interface
•
Control Contact (Loud Bell / Door / External Page Control)
•
External Paging Equipment Interface
•
RMP Serial Port - for on-site PC-DBA system database programming
•
SMDR Serial Port - for connection to ancillary SMDR/Call Accounting equipment
The CPM has two Option Strap jumpers one for database start-up (J11) and one for Music Channel One
source (internal/external) selection (JP30).
J11 Cold Start/Normal: J11 is used to force load database default factory settings. This jumper will
normally never require operation after the initial power up sequence is completed. However should the need
arise to return the site database to the factory settings this jumper is used to accomplish the task.
JP30 Internal/External: JP30 is used to select the Music Channel 1 source. The DX-80 provides a
synthesized music source for music on hold in applications where no music source is available. The
synthesized tune is repeated. JP30 is in the "External" position when it ships from the factory.
408M (KSU1 component)
The 408M is the large circuit board that is packaged inside of KSU1. The 408M provides interface for up to 4
loop-start CO Lines and 8 Digital Extension Ports. Additionally the 408M regulates the 24 volt DC power
from the source to produce all required logic voltages and operations voltages. There is also a Power Failure
