Strata DK General Description 6/00 19
Strata DK424i 3
This chapter covers the new Strata DK424i digital business
telephone system.
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 13~15 for details.)
The system line and station capacity can be increased by
adding additional cabinets (see Figure 9 and Table 10)
which have universal slots capable of interfacing with most
line, station, and option interface PCBs available with the
system.
Architecture
The Base Cabinet and optional Expansion Cabinets are the building blocks of the system. Each
system has a Base Cabinet, and can have from one to four Expansion Cabinets. All lines, stations,
and options are tied together through the cabinets.
