INSTALLATION
Before installing your phone, review the Safety Instructions located at the
front of this manual. Make sure you have the correct model Teleset and
associated parts for your applications. Choose a flat work surface with
good lighting and easy access to cords and jacks. Avoid placing the
Teleset where it is exposed to sunlight or heat sources.
Parts List
Check the box for the following:
Teleset
Handset and Handset Cord
Mounting Cord (8-pin, round)
Designation Card and Faceplate
Wall-Mount /Desk Stand Base
Handset Holder
Logo Plate
As you unpack the box, inspect each part carefully for damage. Report
any damage to your dealer or shipping company. Keep the box and
packing material should a return be necessary.
ISDN Interfaces
A little background information sometimes helps. Your ISDN service
comes to you over ordinary telephone line wiring. That makes it less
expensive and simple to install.
The service provider (telephone company) usually provides a 2-wire
interface, called a U interface to the customer. The i2021 is a Basic Rate
ISDN, S/T interface device. An NT1 device is required to convert the 2-
wire U interface from the service provider to a 4-wire S/T interface. See
Fig. 2.
The S/T interface and power connection cable is connected to the “Line-In”
jack located on the bottom of the Teleset. The i2021 S Teleset must be
connected through a network interface device (NT1). This device presents
the 2-wire U interface to the line, and to the 4-wire S/T interface to the
Teleset. The Teleset is usually powered from the NT1 or separate
transformer.

i2021 ISDN Teleset
Fig. 2: Line and Power Jacks
Line and Power Connections – i2021 Teleset
The i2021 Teleset must be connected to the line through an NT1 device.
This device presents the 2-wire U interface to the line, and the 4-wire S/T
interface to the Teleset. The Teleset is powered over the phone line. This
method conforms to a standard using one of two different powering
methods: PS1or PS2. Powering method PS2 is preferred. Check with
your equipment provider or system administrator for guidance in setting
the PS1/PS2 switch. Your equipment provider should also be asked about
using or disabling the Teleset terminating resistors (TR).
SWITCH SETTINGS:
n
POWER SWITCH
The PS1/PS2 power switch is located on the bottom of the i2021.
n
TR SWITCH
When the i2021 Teleset is connected to the NT1 it acts as Terminal
Equipment (TE). Terminal Equipment is any (ISDN) device that
terminates directly on the ISDN line without a Terminal Adaptor.
If your Teleset is the last, or only, piece of TE on the ISDN line, set the TR
to ON, otherwise it is set to OFF. This is determined by the local
equipment provider’s policy. It is suggested that you check with the ISDN
provider or your system administrator. Most companies allow up to eight
TE units in the loop.

If power is supplied on pins 7&8, set the PS1/PS2 switch to PS2.
If power is supplied on pins 3&6, 4&5 only, set the PS1/PS2 switch to
PS1.
n
n
If power is supplied on pins 3&6,4&5,7&8, set PS1/PS2switch to PS2.
If your NT1 does not supply power, you must use an external 48-volt
DC power supply. Contact your service provider or system
administrator if an external power supply is required. Connect as
follows (Figure 4) and set the PS1/PS2 switch to PS2.
Fig. 4: Powering a Teleset (S/T) with an External Power Supply
Terminating Resistors
The i2021Teleset has built-in Terminating Resistors. The Terminating
Resistor switches are located on the bottom of the Teleset. When the
switches are in the On position, the Terminating Resistors are installed.
The value of the resistors is 100 Ohms.

Point-to-Point Circuits
A point-to-point application typically has the Terminating Resistors “On” at
both ends of the interface.
Fig. 5: Terminating Resistor Range
Passive-Bus or Multipoint
These may be new terms to you, so we will define them so you can better
understand their meaning. Passive Bus means that you can connect
several devices to the same Basic Rate Interface (ISDN line). Improperly
set Terminating Resistors account for many of the problems with ISDN
service. The “short version” of this explanation is that both ends of a bus
or circuit must be terminated.
Your choices of terminating resistance are two: none or 100 Ohms. The
idea is to terminate both ends of the bus. Set the resistors to ON at both
ends of the bus.
The best advice is to follow the instructions given by the NT1 manufacturer
and those of your terminating devices.
In the following configuration, the Terminating Resistors are “On” at both
ends of the interface. The resistors are on at the NT1 and “On” at the
farthest i2021 from the NT1.

In the following application, the NT1 is equal in distance to both
i2021 phones. The Terminating Resistors are set to “On” at one of
the phones and at the NT1.
Fig. 7: Terminating Resistor Settings for Equal Distance Telesets
Line Configuration
To ensure the proper operation of your Teleset, several operating
parameters must be met. This information can be provided by your
system administrator or service provider.
n
SERVICE PROFILE IDENTIFIER (SPID)
A service profile for your Teleset that is recognized by the switch.
Some switches support AutoSPID. If your switch supports AutoSPID,

i2021 ISDN Teleset
the teleset will display the SPIDs for you. Simply choose the correct
SPID. If the switch does not support AutoSPID, you will have to
manually enter the SPID. Check with your service provider or system
administrator for the correct information.
n
n
DIRECTORY NUMBER
The telephone numbers appearing on your line.
CALL APPEARANCE KEYS
These are configured at the switch and at your phone. You may have
more than one Call Appearance of a Directory Number. Check with
the system administrator or service provider for information and
multiple Directory Numbers. With National 2 and 3 ISDN, many of the
required settings can be automatically downloaded from the switch –
see your system administrator or service provider for details.
FEATURES
Conference, Drop, Transfer, Call Forwarding, and others may need to
be programmed in the Teleset.

Softkeys
An understanding of softkey operation is required in order to install and operate
the i2021 Teleset. Directly below the display are four softkeys, vertically-
oriented to the display. The location of these keys corresponds to menu
choices that appear directly above them in the LCD window. For example,
pressing the softkey below the “clock” menu reveals the options for setting the
time of day and date. They are called softkeys because their function changes
according to the menu. In one menu a key may set the time, while in another
menu the same key is used to choose a feature. This will become clearer as
you begin using the softkeys. See the following example.
Example:
Press the softkey under Directory — shown below by highlighting (bold
type) the word “DIR” and highlighting the softkey below that menu item.
Pressing the Directory softkey brings up the second menu with additional
choices. In our example we chose Search next — shown in bold type.
The selected menu items are shown in bold type for emphasis. The
softkey under Search is highlighted to indicate the chosen softkey.

power is reset.
2ND RING
The 2nd Ring option controls how the Teleset audibly reacts to an incoming
call on another Call Appearance when you are already off-hook on an
active call. The choices are Continuous Ring, Partial Ring, and No Ring.
With Continuous Ring, the Teleset will sound the 2nd Ring “beep” with
every ring cycle.
With Partial Ring, the Teleset will sound the 2nd Ring “beep” with a shorter
duration every other ring cycle.
With No Ring, there will be no audible ring during the ringing cycle.
NOTE In all cases the Call Appearance LED will flash, and the
display will continue to show the Calling Line ID if
available.

Executive/secretarial applications.
Conjunction with RLP (Ringing Line Preference).
User line identification.
The Primary Line feature works in conjunction with Ringing Line
Preference. Ringing Line Preference allows the Teleset to automatically
go off-hook on the oldest ringing Call Appearance when the handset is
lifted. This may be a problem if the Teleset is sharing telephone numbers
with another phone, such as in a manager/assistant application. In this
arrangement, the secretary receives an incoming call and the phone starts
to ring. A fraction of a second later, the manager receives an incoming
call. If the manager and secretary both have each other’s telephone
number appearing on their phone, the oldest call will be answered first.
This is no problem if the secretary answers first. But if the manager
answers first, the manager will get the secretary’s call.
This problem is easily avoided if the manager and the secretary set their
respective Call Appearances as Primary.
NOTE: PrimCA gives the phone Ringing Line Preference only on
the Primary keys.
To set Primary Call Appearances:
1. Press MENU, MORE, MORE, Config, MORE, PrimCA. The Teleset
will display the following message and a number of Call Appearances
will light.
2. The Teleset defaults to all Call Appearances are Primary. Therefore,
all of the Call Appearances will light green.
3. One at a time, select the Call Appearances that are not Primary to
your Teleset. The Teleset will prompt you to press the key twice to
confirm your selection.

4. If you encounter a red Call Appearance key, the Teleset will display
the message, “Invalid-Not a General CA”. This means the Call
Appearance has previously been programmed as a Conference,
Priority, or a Terminate Only Call Appearance. If this is the case, you
must first go to the Conference, Priority, or Terminate Only Call
Appearance screen and change the key back to a General Call
Appearance.
PRIORT CA (PRIORITY CALL APPEARANCE)
Priority Call Appearance is a feature offered by some switches. Priority
Call Appearances are not widely available today. To set a Priority Call
Appearance, press MENU, MORE, MORE, Config, MORE, PriortCA in
order. Select the Call Appearance to be used for Priority – it will light
green.
NOTE: Only Non-PrimCA keys can be programmed as a
PriortCA. You must first change a PrimCA key to a
General CA key.
CONFCA (CONFERENCE CALL APPEARANCE)
To perform a conference or transfer, you need a second Call Appearance.
Your Teleset automatically selects the next available Call Appearance
when the Conf/TR or Confr key is pressed.
A word of caution is appropriate here. The next available Call Appearance
may be someone else’s (Shared) Primary Call Appearance. To avoid this
problem, press MENU, MORE, MORE, Config, MORE, ConfCA in order.
Select the Call Appearance to be used for conference – it will light green.
NOTE: Only Non-PrimCA keys can be programmed as a
ConfCA. You must first change a PrimCA key to a
General CA key.
It is also recommended that the service provider option this Call
Appearance for outgoing calls only. Only one Call Appearance can be
designated as ConfCA.
TERM ONLYCA (TERMINATE ONLY CALL APPEARANCE)
Terminate Only Call Appearance is a feature offered by some switches
and is not widely available today. To set a Terminate Only Call
Appearance, press MENU, MORE, MORE, Config, MORE, TermOnlyCA

ADVANCED FEATURES
DSS/BLF (Direct Station Select, Busy Lamp Field)
DSS – This feature allows calls to be transferred to a station without
dialing the station on the keypad.
BLF – For use by attendant consoles - When an incoming call rings the
main number, an attendant can use this feature to check the status
of a line for a busy condition. If inactive, a call may then be
transferred by using the DSS key.
NOTE: Only Non-PrimCA keys can be programmed as a DSS key.
You must first change a PrimCA key to a General CA key.
PROGRAMMING A DSS/BLF (DIRECT STATION SELECT / BUSY
LAMP FIELD) FEATURE
TO PROGRAM A DSS/BLF
1. Ensure the Call Appearances to be used for the BLF are set to
General Call Appearances.
2. Press MENU, MORE, MORE, MORE, DSS/BLF
3. Select a Call Appearance. Press it a second time to confirm your
selection.
4. Press the SetAddr softkey. If your line is a Centrex line, the DN must

call will be transferred.
NOTE: When a Call Appearance is programmed as a DSS/BLF,
the user cannot bridge onto an active call. The key no
longer operates as a Shared Call Appearance.

Disabling Softkeys
Sometimes a softkey feature will appear on the display and not be
available to the user. For example, the PkUp key appears on the display
but the Call Pick-Up feature is not available to the user. Other times a
user may prefer to have a hardkey and an LED indicator for a feature.
Many users prefer moving Call Forward to a hardkey.

Key Mapping
The i2021supports a local feature called Key Mapping. The purpose of the
Key Mapping feature is to allow features that have Feature Activators
higher than Key 16 to appear on a hardkey.
For example, the North American ISDN Users Forum (NIUF) recommends
using Key 57 as a Call Forward key. Key 57 defaults as a softkey on the
i2021 Teleset. Key Mapping will allow Feature Key 57 to be “mapped” to a
hardkey on the i2021. This may be useful, since the Teleset would now
light the hardkey’s adjacent LED when Call Forward Feature Key is active.
To remap a hardkey press MENU, MORE, MORE, Config, SetKey. The
display will now be:
Press MapFA and the display will be as shown below.
Press the hardkey that you would like to remap. If you select a key that is
not available you will be prompted to “Try Another Key.” When you select
an available key the display will show:
58

i2021 ISDN Teleset
NOTE: Key (xx) will be the number of the hardkey you select. At
this point, use the dial keypad to enter the Feature
Number (Activator/Identifier) that you want to appear on
the key you selected. In our example, we entered 57.
Press Save to remap the key.
Press MENU to exit the idle menu. At this point the hardkey you selected
will be the Feature you entered. Pressing that key will activate or
deactivate (toggles) the feature. For a complete list of the NIUF
recommended Feature Keys contact your service provider.
NOTE: Only feature keys can be mapped to a different key. Call
Appearances cannot be remapped.
Inspect
Inspect is a National ISDN feature. Check with your local service provider
regarding the availability of the Inspect feature. If available, your service
provider will assign this feature to one of the keys on your Teleset.
NOTE: In order for the Inspect feature to work, it must be
assigned to one of the programmable hardkeys
(designated 1 through 16). Choose a key after your Call
Appearance keys are designated. For example, if we
designate keys 1 through 5 as Call Appearance keys, we
can then select any key between 6 and 16 as our Inspect
key.
The purpose of the Inspect key is to allow the user to query the serving
switch as to what features or Call Appearances are assigned to a
particular key on the Teleset.

i2021 ISDN Teleset
The i2021 Teleset contains feature keys up to key 96. Feature keys above
key 16 are automatically assigned to softkeys. However, all keys may be
mapped to hardkeys if desired. For further information, refer to the
paragraph that explains “key mapping.”
To Use the Inspect feature, press the Inspect Feature key.
You can then either press one of the hardkeys (1-16), or enter a number
on the dial keypad. For example, suppose you wish to inspect key 2. First
press the Inspect key, then press key 2. The switch then displays the Call
Appearance, or feature, assigned to key 2. Perhaps you wonder what is
assigned to key 60? To find out we must remember that keys over 16 are
automatically assigned to a softkey. Since key 60 is a softkey, you must
enter 60 followed by a # sign, on the keypad. The switch then displays the
Call Appearance or feature assigned to key 60.
NOTE: Inspect is a timed feature in the switch. After pressing
the Inspect key, you are given about ten seconds to
enter the key number that you wish to inspect.
INSPECT OR VIEW?
The i2021 Teleset has a “local inspect” feature built into the Teleset. The
local inspect feature is called “View Key”. Refer to the paragraph that
explains View for additional information. What is the difference between
Inspect and View? View shows the user the Teleset information about a
specific key. Inspect displays what the switch has actually assigned to
that key.
View
View is a feature that is local to the phone. It will only reflect the current
programming of the phone. To ensure accuracy, perform a Parameter
download before using View Key.
Key assignments should be checked if features/options do not seem to
work correctly. Often the Teleset is blamed for incorrect or missing key

The Directory Numbers assigned to the Teleset are easily viewed by
pressing MENU, View, DN.
The Teleset will light the appropriate Call Appearance keys and display the
DN assigned to them. This is helpful when checking Multiple Call
Appearances or labeling the Teleset.
Protecting Keys from Being Overwritten
Once the Teleset has been completely programmed, it is possible for the
serving switch to change the Teleset’s programming. This feature is
called Auto-Parameter Downloading. Like all features, there are pluses
and minuses to it. On the plus side, the Teleset will always be in
agreement with the switch. On the minus side, the switch can erase
Speed Dial keys, remapped keys, etc. without the user’s knowledge.
There are two different methods for protecting the Programmable
Hardkeys. The first is to disable the automatic download. The second is
to allow the automatic download but protect the keys on a key-by-key
basis.
