DK424i Configuration
This chapter contains information and worksheets to help configure the DK424i systems. A
system overview of DK424i components and the maximum station and line capacities available
with each system processor is provided. Worksheets follow this information to aid in determining
the actual interface PCBs needed for particular proposals and how these PCBs should be placed in
DK424i cabinet slots. (Worksheets begin on

System Overview

Strata DK424i easily connects to outside public telephone
lines (CO lines). All of the telephones (stations) tied to the
system can have direct access to each other as well as to the
public network.
A modular design and a choice of four processors, also
called common control units, enables the system to fit a
variety of customer needs and capacities.
The DK424i can be configured as a single cabinet system
that provides capacity of up to 64 CO lines and stations
combined, and can grow to a five cabinet system that
provides capacity for up to 432 CO lines and stations
combined. These capacities assume that one slot is reserved
for an optional External Page/Maintenance interface PCB.
(See Tables 6-4~6-6
The system line and station capacity can be increased by
adding additional cabinets (see
which have universal slots capable of interfacing with most
line, station, and option interface PCBs available with the
system.
