DRD-4CHAPTER 2: Introduction

2. Introduction

NOTE: The name “Distinctive Ringing

Service” may vary with each

telephone company. This service

may not be available in some

locations. Contact your local

telephone company to verify that the

service is available in your area.

The DRD-4 is compatible with any

telephone device that responds to

a standard phone company ring

signal. This guide defines a few of

the more popular combinations

used with the DRD-4.

2.2 Ports on the DRD-4

The rear panel of the DRD-4 includes

five modular ports and a power input

port, as shown in Fig. 2-1.

2.1 General

The DRD-4 deciphers the

“Distinctive Ringing Service”

provided by the telephone company.

This service uses a single phone line

for multiple phone numbers and

assigns a unique ring identity to each

number. Working with this service,

the DRD-4 identifes and directs each

of the four ring types to a designated

telephone device. You can connect

up to four different telephone

devices to a single telephone line,

giving you automatic operation and

eliminiating the need to flip switches

and turn machines on or off.

STYLE 4 port—This port rings with

a short-long-short ring cadence. Use

this port for any telephone device

that you wish to respond to the

the phone company.

• The DRD-4 recognizes each ring

cadence and automatically

directs each call to its intended

destination.

• The DRD-4 allows any phone

directly connected to the unit to

answer all phone calls during the

ring signal. Once you answer a

call, the DRD-4 will not allow any

of its ports to interrupt a call to

another port. This feature

ensures your privacy during

phone calls and guarantees data

integrity when you use data

equipment.

NOTE: Only the phones connected to a port

will ring when calls are directed to

that port, but you can answer those

calls from other phones.

3. Installing the DRD-4

To install the DRD-4, you will need

the telephone cable (included) and

an additional cable for each device

you wish to connect to the DRD-4.

If the equipment you wish to

connect to the DRD-4 is not located

near the unit, you may need

extension cables.

3.1 Installing the DRD-4 on a Single

Line

Fig. 2 shows the DRD-4 installed on

a single telephone line.

You can install the DRD-4 on any

system with single- or two-line

phones, including key service unit

(KSU) or private branch exchange

(PBX) multiple-line phone systems.

This chapter explains how to install

the DRD-4 in four different phone

configurations:

• A single line

• A single line that maintains

exclusion

• Two lines with single-line and

two-line phones (with the DRD-

4 connected to one extension)

• A KSU/PBX system

CHAPTER 3: Installing the DRD-4

To install the DRD-4 on a single line,

follow these steps:

1. Plug the small end of the AC

power cord provided with your

unit into the plug labeled

“12VAC” on the back of the

DRD-4.

2. Plug the AC adapter into any

standard 110-volt outlet. The

green indicator lights on the

front of the unit momentarily

flash on and off in a self-test

pattern. The lights then remain

off.

3. Plug one end of the telephone

cable provided with the DRD-4

into the TEL LINE-IN port on

the back of the unit.

4. Plug the other end of the

telephone cable into the wall

jack.

5. Connect your telephone

equipment to the ports

DRD-4

NOTE: With the installation shown in Fig. 3-

1, calls will only be routed to phones

connected directly to the DRD-4.

Phones not connected directly to

the DRD-4 will ring with each ring

cadence and will be able to interrupt

any call. For total automatic

operation and protect against

interruption, install the DRD-4 as

shown in Figure 3-2.

3.2 Installing the DRD-4 on a Single

Line with Multiple Phones and

Maintaining Exclusion

When you connect the DRD-4 to a

single line with multiple phones, you

may want to maintain exclusion.

Exclusion means that if one phone

line is in use and you pick up a

phone on another line. the first

phone line is not interrupted and

you get a busy signal. To maintain

exclusion, the incoming phone line

must terminate at the DRD-4, and all

phones must connect to the DRD-4

ports. See Fig. 3-2.

NOTE: You should be familiar with

telephone wiring to complete this

installation. Call Technical Support

for instructions or contact a

professionai installer.
