LINE TYPES

Line Select keys *

Of the 15 keys on the upper right side of your
SUPERSET 4TM, the 14 uppermost can be used as
line select keys and speed call keys. The lowest
key of that group is your prime line. To meet the
various telephone needs of your department, these
keys may be used for various types of lines. They

are called line select keys because you use them
to select a line. The various types of lines are
described below.

Types of Lines

Prime Line

The lowest line select key on the upper right side

of your SUPERSET” telephone is your Prime Line
(directory number). When you lift the handset or
press the Speaker On/Off key, this line is selected
automatically,

Key Line
Key lines are shared by other extensions. Typically,

a key line is programmed as an appearance of the
prime line of a co-worker. This means that a call
ringing another extension can, if the need arises,
be answered with the push of the key line button.
Only one person can use a key line at a time; the
only exception to this rule is when you are using a
key line appearance of a regular extension, in

which case the regular extension user can still

make outgoing calls on the line. The system will
ignore the request of other users trying to select

the line. You can retrieve a call put on hold on a

key line from any SUPERSET sharing the same line.

I-6 Overview

LINE TYPES

Multicall Line

The Multicall line shares its directory number with

other extensions. Incoming calls ring all the
extensions sharing the line. As soon as one of the
users sharing the Multicall line answers, all the
other extensions stop ringing. The line then
becomes free for all the other users sharing it, to
make or receive calls.

If you place a caller on hold on a Multicall line, no
other extension user may retrieve the call from

hold.

Direct T&k Select (DTS)
When a DTS line is accessed, you are connected
automatically to an outside trunk, and the dial tone
you hear comes from outside your telephone

system. ‘This means that you will not have to dial a
trunk access code before the desired number. Only
one person can use a DTS line at any time. You
can transfer a call on a DTS line by pressing the
TRANWCONF key.

Direct Line Select (DLS)
A DLS line is essentially the same as a DTS line
with the following exceptions: calls cannot be

placed on hold or transferred using TRANSKONF;
calls can be only be extended to another

SUPERSET’ set which has a DLS appearance of the

same trunk, by putting the call on hold using the

red hold key, and the call must be retrieved from
the other set.

In addition, conference calls can only be formed
with other SUPERSET sets with an appearance of
the DLS line, by using the Privacy Release feature.

Overview l-7

LINE TYPES

Private-Line
A Private line is similar to the Direct Trunk Select
line, except that you cannot transfer a call on the
Private line or include it in a conference. In
addition, your Private line can only appear at your

telephone and on no other SUPERSET” in the

system.
Personal Outgoing Line

The Personal Outgoing line is a Multicall

appearance of your prime line that allows you to
make calls while your prime line is busy. You

cannot receive calls on a Personal Outgoing Line. It
can appear only on your telephone and on no other
SUPERSET in the system.

Contact your Communications Department if you
have any questions about the programming of your
line select keys.

Speed Call

Line select keys may be used as speed call keys if
they are not already programmed as a line
appearance (see SPEED CALL KEYS in the Features
section of this Guide).

I-8 Overview

Line Appearances

When someone else’s line is assigned to or

appears on your set, it
appearance”. For example, if your colleague Jim’s
line is programmed on one of your line select keys,
his line is said to “appear’ at your set.

When someone calls Jim, a symbol will flash on

your line status display, next to the line select key
corresponding to his line on your set. When Jim is
using his line, another symbol appears on your line
status display. The symbols that appear in the line
status display are illustrated below.

FEATURE DISPLAY AND SOFTKEYS

The Feature Display . . .

is the alphanumeric Liquid Crystal Display located

in the middle of your SUPERSET qTM set.

The upper portion displays instructions and
messages. Prompts appear in the lower portion of
the display. Prompts are feature names, words, and
symbols that guide you in using your SUPERSET 4

set. The diagram below shows the display when

the set is idle.

2~44

PROGRAM

The six buttons below the Feature Display are
referred to as “softkevs”. Prompts appear above
the softkeys in the Feature Display.

Each softkey is used for more than one prompt, so
the prompts in the display change according to
what features you are allowed to use on your
SUPERSET 4 set at that particular time.

The diagram below shows . . .

all of the feature prompts that may be displayed on
your Feature Display.

Note: Depending on the way your SUPERSET@ was

programmed at installation time, some of

these prompts may not appear on your set.

Any time a prompt is displayed, you can select that
prompt by pressing the softkey below it. For
example, pressing

first diagram below). Prompts only appear when
they can be used. Nothing happens when you
press a softkey without a prompt being displayed
for that softkey.

The two diagrams below show examples of other
possible displays. By comparing these two

. examples, you can notice that the same softkey is

used for different features and that sometimes a
softkey has no effect.

speaker on/off

The speaker on/off key lets you make or receive

calls without lifting the handset. This is referred to
as “handsfree operation”.

The speaker on/off key enables the speaker and

microphone on your set. You can hear the caller
through the speaker; you can speak to the caller

through the microphone located on the bottom

right corner of your SUPERSET qTM set. The section
“Handsfree Operation” gives the procedures for
using your SUPERSET 4 set in the handsfree mode.

,The other type of handsfree operation available is

Automatic Answer. See AUTO ANS.

mic. on/off

The mic. on/off key lets you consult privately
during a handsfree call. When you press the mic.
on/offkey, the speaker is kept on, but the
microphone is turned off.

The caller cannot hear you, but you can hear the
caller through the set’s speaker. In this way, you
can talk to someone privately in your office
without the caller hearing.

During handsfree operation, the words “MIC ON”
appear in the Feature Display. This means the

microphone is on. When you press mic. on/off,
“MIC ON” disappears. In this way, you can
doublecheck that the microphone is turned off
when you use the mic. on/off feature.
