Electra Elite IPK
The KSUs are built for modular growth. The Electra Elite IPK KSUs are stacked
vertically for quick interconnection. Printed circuit boards, called Electronic Telephone
Units (ETUs), provide common control and interface to equipment that is external to
the KSUs.
Interface ETUs are installed in the KSU to support the various telephones, outside
lines, and other devices or features. The same ETUs are used for both the basic and
expanded port packages.
The universal slot design minimizes the hardware required for a system and provides
greater flexibility in the number and types of devices that can be installed. Refer to
Figure 1-3 ETU Slot Design
.
The Electra Elite IPK KSU contains an application (AP) slot, a CPU/EXP ETU slot,
and 8 interface slots. A power supply and battery backup area complete the KSU.
The Electra Elite IPK system allows connection of a variety of telephones. The
different needs of the customer may require various types of telephones.
