Introduction/How the
SR Call Processor Works 1
Congratulations! You are now the owner of
the highest quality Selective Ring
Call
Processor on the market - The SR series.
We at Multi-Link value
you as a customer and
have provided you with this manual and a Warranty Registration Card.
Please read the manual carefully and be
sure to fill out all the informatioti
requested
on your warranty card. Should you need technical assistance,
please
call our Technical Support department at 800-535-4651. Thank you
for selecting Multi-Link for your communications management needs.
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)

SRSr

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
Device 3
Devices Used (examples)
Telephones
FAX
Computer Modem (SR3 only)

Featuresand
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.

Installation
Your SR Call Processor, when properly
installed and configured, can link together a
variety of telephones and data
communication products, including FAX machines, MODEMs, credit
authorization terminals and answering machines.
Proper Installation Is Important!
You probably won’t be able to plug your SR in just anwhere and get the
desired
results. Please read the following paragraphs to better understand
how to
install your SR.
To understand the importance of proper installation and placement, think
of your SR
Call Processor as a telephone “traffic top” that supervises
traffic through
an intersection. Any telephones and data devices that are
attached THROUGH the SR can be allowed to ring, and allowed or denied
access to the telephone line.
Just as a traffic
top cannot control traffic that does not pass through his
intersection, your SR cannot properly control telephones and data devices
that are not connected THROUGH the SR.
There are three factors to consider when chosing
an installation method.
They are:
1)
Which phones and data devices require ring supervision?
Any data device that answers calls (FAX, MODEM, answering
machine, etc.) should be connected THROUGH your SR. Phones
that may awaken you at night should
also be connected through your
SR. Certain other phones may be left directly connected to the
telephone line if you
don't need barge-in protection.
8 SR Serles

2)
3)
Do I need barge-in protection?
If you use a data device (FAX, MODEM, etc), V
you should place the “BARGE-IN” switch
in the “ON” position.For
your SR to properly provide barge-in protection, any telephone or
other device that could interrupt the
call or data transfer must be
connected THROUGH the SR. If barge-in protection
is not required
(for example,
in a voice-only application at home), certain phones
may be attached directly to the telephone line.
Ease and expense of changing my telephone wiring.
In most applications, a complete re-wire is not needed. Many homes
are wired
in a way that allows some “tricks” to make installation
easier and
less expensive.
Several methods of installation are described in the following pages. Each
has advantages and limitations.
If you feel uncomfortable at any point with the installation procedures, we
recommend that you contact your dealer for assistance.
You may also
want to contact your telephone company or an independent installer to
assist you with any wiring changes that may be necessary at your
site.
For Safety
Your telephone company has probably installed a small box called a
lightning
arrestor near where the telephone line comes into your
building or home. Both the incoming line and the wire(s) servicing your
phones and equipment are attached to this box. Under no
circumstances should you disconnect or alter the wire going from this
box toward the telephone company. The only wires and connections
you should change are those going from this box toward your
equipment.
SR Series 9

You will need to apply power to your SR with the
supplied AC adaptor. Be
sure to pick an installation V
location where a grounded 110VAC power outlet is nearby. You will also
want to set the switch(es) on your SR for your particular application (See
inside front cover).
Initial Check Out
Please
check the box and make sure you have:
-either an SR2 or SR3 Selective Ring Call Processor
-a 12 VAC
Class 2 power source
-one silver modular line cord with
RJ-11 plugs on each end.
-a Warranty Registration Card
If any of these items are missing, please
alert the retailer from which you
purchased your SR
Call Processor and also Multi-Link, Inc. at
1-606-885-6363.
The following installation examples describe the best ways to attach your
SR to either a single or multiple line telephone.
Each is described with a
rating of how the installation handles ring supervision, barge-in protection,
and ease/expense of installation!
NOTE:
All installations described on the following pages assume that your
existing telephones will be rung by your primary number that generates a
single ring, and that your data equipment or
special phones will be rung by
the additional numbers that
generate multiple rings. If necessary, after
following these instructions, you may need to rearrange the number
assignments by rearranging the DEVICE
port connections on your SR.

an installer if you need additional help.
1) Choose a suitable location for your SR. One good place to consider
is
near the point that the telephone line enters your home or building. Other
good places are where existing telephone jacks are located.
2) Disconnect the telephone company’s line from
all of your existing jacks,
but
leave the jacks still wired to each other. This needs to be done at a
point
BEFORE the incoming line splits off to other extensions.

3) If you disconnect the incoming line from a jack, label the existing jack
“TELEPHONES”. If you did not, install a jack, label it “TELEPHONES”, and
connect the two wires going toward your phone equipment to the RED
and GREEN terminals of this new
jack.
4) Mount a modular jack* at the location of your SR and connect the
telephone company incoming line to the RED and GREEN terminals. It
may be necessary to run additional station wire* from the incoming
line.
Label
this jack “LINE”.
5) Connect the “LINE” input of your SR to the modular wall jack marked
“LINE” with the supplied line cord. Connect the wall jack marked
“TELEPHONES” to the DEVICE 1
jack on your SR with a line cord.
6) Attach any other telephones or data equipment to the other DEVICE
jacks
on your SR.
7) If you need to attach
an additional telephone to DEVICE 1 at the SR,
you can use a telephone line “Y” adapter* to allow you to plug two line
cords into the DEVICE 1
jack.

If your home has 4 or 6-wire cable to each wall jack, you can make your
installation look electronically like installation B by using
special 2-line (to
1-line) splitter
adapters*. The adapters will utilize an unused pair of wires
in your home to connect your telephones.
1) Choose a location where there
is an existing wall jack and where only
one phone or data device will be connected BY ITSELF to a DEVICE
jack.
You will install your SR at this location.
2) Unplug anything connected to this wall jack and plug the 2-line
adapter*
into the wall jack.
3) (READ CAREFULLY) Connect the “LINE” jack of your SR to the
“LINE 1” side of the 2-line adapter with the supplied line
cord.

adapter with a line cord.
5) Connect your data devices and/or other telephones to the DEVICE 2
(or 3)
jacks on your SR. These devices or phones will be rung by your
additional telephone number(s).
6) For
each wall jack in your home, disconnect anything plugged into it.
Insert a 2-line adapter and re-connect the cord to the
,“LINE 2” side of the
adapter. If it
is impractical to insert a 2-line adapter (for example, with a
wall-mount telephone), convert this jack by:
a. Swapping the GREEN wire with the BLACK wire
b. Swapping the RED wire with the YELLOW wire
Then plug the phone
back into the converted jack.

In reality, this installation is fast, easy, and works great if you don’t need
barge-in protection and if you
don't care if your other phones ring all the
time. The best application
is adding a FAX, MODEM, or answering
machine on the second number. The obvious drawback is that even if you
turn the barge-in switch “ON”
on your SR, you can still interrupt a call with
your extension phones.
1) Choose a location with
an existing wall jack to add your additional
equipment. Unplug any cord from the wall
jack. Connect the “LINE” jack
of your SR to the wall jack with the supplied line cord.
2) Attach your equipment to the proper DEVICE jacks on your SR. You
can also re-attach a telephone to DEVICE 1.

less expensive than changing your wiring, especially if your site is wired in
a user-unfriendly way, or if your extensions are in other buildings.
For
EACH location where you want the phone or data device to ring on
only one number:
1) Unplug any cord attached to the
wall jack. Connect the “LINE” jack of
your SR to the
