Printed Circuit Board (PCB) Installation
PCB Hardware Options
Each PCB must be configured for the applicable hardware options prior to installation of the
PCB. Configuration instructions for internal hardware options are provided in the individual
PCB installation procedures in this chapter and Chapter 4–DK40 Universal Slot PCB Wiring.
Configuration instructions for external hardware options are provided in Chapter 6–
Peripheral Installation.
PCB Software Options
After installation of the PCBs in the KSU, configure the PCBs for software options through
programming. A programming overview for each PCB is provided in this chapter. Refer to

Digital Telephone Circuits

The eight digital telephone circuits that come standard with the system are integrated into the
DK40 motherboard in the Base KSU. These circuits are identical to the digital circuits found
on the PDKU. The motherboard does not have to be configured for the digital circuits to
operate. For wiring
