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

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.
