DK424 Configuration
This chapter explains how to configure the Strata DK424 system. The system has a modular
design which enables it to support a number of station and CO line configurations. The main
component of the system is the common control unit (RCTU) Printed Circuit Board (PCB).
The focus of this chapter is a series of worksheets, providing a systematic procedure for
determining the system's size. The worksheets also provide space to record the hardware and
station devices that make up the system. Tables and example worksheets are included to assist you
in filling out the worksheets.

The DK424's main components are: the DK424 Base Cabinet (DKSUB424), DK424 Expansion
Cabinets (DKSUE424), and four system processors (RCTUA4, RCTUBA3/BB4, RCTUC3/D4,
and RCTUE3/F4). The processor used in the system depends on the features and number of
telephones and CO lines required. Each cabinet is shipped with its required Power Supply
(RPSU280); the same power supply used in DK280 cabinets.
