Overview
This section describes the purpose and functionality of the main components of the system. By
understanding how these components work, you can easily configure a system that meets your
specific needs.
This section is divided into the following categories:
Cabinets
The DBS 576 cabinets are explained in detail below. Both the base cabinet and the expansion
cabinet share the same PCB cards. Both cabinets can attach to any of the proprietary
43-Series and 44-Series
power supply, and is designed with
extension, and
Common Cards
The common cards control the signaling and features used by all other cards in the system.
Without common cards, other cards cannot function. The common card which is considered the
"brains of the system" is called the Central Processor Card, or CPC. Each phone system
requires a processor to operate.
Telephone Company Interface Equipment
Panasonic offers a wide variety of interface circuits that allow the DBS 576 to attach to Central
Office (CO) and/or common carrier equipment. This interface equipment is explained here in
Chapter 2.
Station Interface Equipment
The DBS 576 allows for connection of Panasonic
telephones as well as various analog telephones and devices provided by other manufacturers.
This chapter includes descriptions of the cards and equipment needed to accomplish these
connections.
Optional and Miscellaneous Equipment
The cards and interfaces that provide optional services, and all miscellaneous equipment, are
explained later in this chapter.
Station Equipment
All Panasonic proprietary stations are explained later in this chapter.
