PART 1. SYSTEM OVERVIEW

1.1 INTRODUCTION

The DS 616, Digital Communication System, is a digital telephone system designed for
the small to medium-size businesses. DS 616 is easy to install and maintain, convenient
to use and flexible to accommodate a variety of features. The system employs the very
latest DSP technology (Digital Signal Processors).
DS 616 provides interface cards that allow connection to the public telephone network or
private networks. These are generally referred to as trunk cards. In addition to the trunk
cards the system provides option boards for serial interface and auto attendant. Two types
of telephones can be connected to the systems. Proprietary digital phones called "keyset"
connect to digital line interface (DLI) ports of the system. Standard telephone sets gener-
ally called "Single Line Sets" connect to single line interface (SLI) ports of the system. In
addition, DLI station ports are used to connect peripheral devices such as door-phone
interface modules. Miscellaneous circuits are provided to allow such optional features as
external paging, music on hold, background music and general-purpose dry contact.
All DS 616 keysets utilize a single PCB with surface-mounted components assuring the
highest product quality and long life. In many instances, sophisticated features are made
simple through the use of friendly display prompts or push-on/push-off feature keys.
