A Word About the “Distinctive Ring

Service”

Your local telephone company has provided you with an inexpensive
“Distinctive Ring” service which

increases

your communications capability.

The service goes by different

names

depending on the telephone company

-Custom

Ringing

by U.S. West, Smart

Ring

by GTE, Ring

Master

by

Bell

South, Ring

Mate

by NYNEX,

Personalized Ringing

by

Southwestern

Bell, Call

Identification

Service

by Ameritech, Ident-a

Ring

by

Bell

Atlantic, etc. These services

all

work in the

same

manner. Two, and
sometimes three, different numbers can be requested from the phone
company. The numbers ring through a single line coming into the
business or residence and

each

number can be distinguished by the
pattern of the ring. These ring patterns are made up of various
combinations of ring bursts. Examples of the different ring patterns would
be:

Original Number

1 Regular Ring

Second Number

2 Short Rings

Third Number

3 Rings (Shorts and Longs)

How

The SR Cal1 Processor

Works

The SR

Call

Processor counts the number of bursts in the ring pattern of

the telephone number

called. It

then directs the

call

to one of the

numbered device ports at the rear of the unit. The device ports are output

jacks

that connect your phone devices (phones, MODEMs, FAX, answering

and dictation machines) to the SR

Call

Processor. When you

have

attached the phone devices you wish to use, the SR

Call

Processor routes

each

different ring pattern

(i.e.

telephone number) to a specific phone

device

without

ringing

other phones on the

same line.

Example:

Ring Pattem

Port

Original Number

Device 1

Second Number

Device 2

Third Number

Features and

Applications

There are

many

applications for your SR

Call

Processor in the home or

small

business. To

optimize the phone configuration that

is

best

for you, it

is

important to understand the

features

available from your SR

Call

Processor.

FEATURES

Exclusion

Feature

-

Both SR models

have an

exclusion feature which
allows you to control line accessibility between your phone devices. This
feature can be activated by the protection switch labeled

“Barge-In” on

the

front

panels

of the SR2 and SR3.

(See

inside front cover for end-panel

view).

1) “Barge-In”

Protection

On

-

This setting enables you to protect

phone conversations and data transmissions from being interrupted by

other phone devices

on

the

same

line. When extensions are picked up

a busy

signal

will be heard.

2)

“Barge-In”

Protection Off

-

This setting allows you to answer any

incoming

call

from any extension in the home or business. In addition,

you can conference any

call

from any extension.

Surge Protection -This feature is standard for both the SR2 and SR3.

Harmful voltage spikes will be carried to the earth ground through the

SR’s

internal

surge suppression network when the SR is properly installed.

2/3 Port Select

Switch [SR3 only]

-

This switch allows you to configure

your SR3 to

operate

with either 2 or 3 numbers. In the “2” position,

calls

will ring through to

Device

2 in the shortest possible time. If you

have

3

numbers, the switch must be set

in

the

“3”

postion.

SR Series

APPLICATIONS

The advantage of

call

routing is to allow you the
capability of upgrading or modifying your
communications network as your needs

change. Here

are a few

applications you may consider.

In The Home

-

With your SR

Call

Processor, you can now assign any

phone device

in

your home its own individual telephone number. Your

children, spouse or roommate can now

have calls

routed to their personal

phones without ringing other phones

in

the house.

Home Office -In the home

office

application, it is important for

each

phone number to be routed without ringing other phone devices in the

house. The SR

Call

Processor will route the phone numbers you

have

assigned to your phone/office equipment to those particular devices.

You

may choose to

have

one number for your family phone, one for your

business phone, and if you

have

a FAX and/or MODEM, one for these. The

routing

process is

completely invisible to the caller. No one will

ever

know

your business

is

operated out of your home.

Small

Business- Shared

office space

by different businesses

is

predominant throughout the

US.

With the SR

Call

Processor, it is possible

for 3

small

businesses to share the the

same

single-line location without

having to share the

same

phone number. If you are a

small

business or

single residence

office

your FAX, modems, dictation and answering

machines may be assigned individual phone numbers.
