About the Key Expansion Module (KEM)
This document describes the Nortel IP Phone Key Expansion Module (KEM) and how to use it
with the Nortel IP Phone 2002 and Nortel IP Phone 2004.
Description
The IP Phone KEM is a hardware component that connects to the IP Phone 2002 and IP Phone
2004 and provides additional line appearances and feature keys. See Figure 1 on page 0.
The IP Phone KEM provides 24 additional programmable keys (with labels) for your IP Phone
2002 or IP Phone 2004. The IP Phone KEM keys are displayed in two columns of twelve keys on
either side of a central Liquid Crystal Display (LCD).
Up to four IP Phone KEMs can be attached to an IP Phone 2002 or IP Phone 2004. With four IP
Phone KEMs attached, the IP Phone can have up to 96 programmable keys.
When an IP Phone KEM is installed on an IP Phone 2002 or IP Phone 2004, the controls on the IP
Phone affect both the IP Phone and the IP Phone KEM.

• A desk-mount bracket and structural baseplate connect the IP Phone KEM to an IP Phone
2002 or IP Phone 2004, or to another IP Phone KEM.
• A wall-mount bracket installs the IP Phone KEM alongside a wall-mounted IP Phone 2002 or
IP Phone 2004.
Adjusting the display
The IP Phone KEM (see Figure 1 on page 0) has 1 LCD between 2 rows of 1 2 programmable k eys
for a total of 24 keys. Each key has a 10-character display label that is set automatically.
To alter the display contrast on the IP Phone KEM, use the Contrast Adjustment option under the
Telephone Options menu on the IP Phone. Any contrast changes you make on the IP Phone affect
the IP Phone KEM. The IP Phone KEM and IP Phone do not have separate contrast adjustments.
For more information on IP Phone settings and controls, see the IP Phone 2002 User Guide
(NN40050-107) or the IP Phone 2004 User Guide (NN40050-108).
NN40050-103NN40050-103
Setup and assembly
The IP Phone KEM mounts on the right side of an IP Phone 2002 or IP Phone 2004 as shown in
Figure 2. It is secured by snapping into a receptacle on the back of the IP Phone using the
desk-mount bracket and structural baseplate supplied with the IP Phone KEM.
The IP Phone KEM connects to the IP Phone 2002 or IP Phone 2004 using the Accessory
Expansion Module (AEM) port on the IP Phone.

Installing the KEM
Use the following instructions to install an IP Phone KEM:
1 Remove the IP Phone from the stand by pressing the IP Phone tilt handle, and pulling the IP
Phone away from the stand.
Note: For the IP Phone 2004, you can also adjust the stand angle to maximum, instead of
removing the stand.
2 Place the connecting arm of the IP Phone KEM behind the IP Phone and align the IP Phone
KEM connection plug to the AEM port on the back of the IP Phone.
Note: An IP Phone 2002 with the product code NTDU76AB34, NTDU76BB34,
NTDU76AB70, or NTDU76BB70 has shorter connector pins than an IP Phone 2002 with
another product code. If your IP Phone 2002 has a shorter connector pin, you must detach
the ribbon cable connector in the IP Phone KEM from the retaining clip and press the
ribbon cable connector into the header connector before you attach the IP Phone KEM.
3 Press the IP Phone KEM and IP Phone firmly together until the IP Phone KEM locks into
place.
4 If connecting a second IP Phone KEM, repeat steps 1-3.
5 The second IP Phone KEM is attached to the right side of the first IP Phone KEM.

6 Attach the IP Phone stand and the IP Phone KEM stand, if removed.
Adjust each IP Phone KEM stand to the same angle as the IP Phone.
7 The IP Phone KEM powers up.
8 The IP Phone KEM uses the electrical connection of the IP Phone 2002 or IP Phone 2004 for
power. It does not have its own power source.
NN40050-103NN40050-103
Using the wall-mount option
The IP Phone and IP Phone KEM combination can be wall-mounted using the optional bracket kit
provided. The second IP Phone KEM is attached to the right side of the first IP Phone KEM.
Adjusting the tilt base
The tilt base for the IP Phone 2002 cannot be adjusted; however, the tilt base on the IP Phone
KEM can be adjusted to match the fixed angle of the IP Phone 2002.
The IP Phone 2004 has an adjustable tilt base. Adjust the tilt of both the IP Phone 2004 and the
IP Phone KEM as desired.
Initializing the KEM
Once the IP Phone KEM has been installed and powered up on your IP Phone 2002 or 2004, the
IP Phone KEM initializes. When this occurs, the IP Phone KEM display lights up and flashes until
it establishes communication with the IP Phone. When initialization completes successfully, the
additional programmable keys on the IP Phone KEM are ready to use.
About the Key Expansion Module (KEM) 4
When you power up both the IP Phone and the IP Phone KEM together, the IP Phone will boot up
first. A tone will sound to indicate that the IP Phone has initialized successfully. The labels will
display on the IP Phone KEM to indicate that it has initialized successfully.
Note: If the IP Phone KEM display does not stop flashing or does not display key labels,
contact your system administrator.
Note: If you install two IP Phone KEMs on your IP Phone, the one directly attached to
the IP Phone (to the immediate right of the IP Phone) must be function al for the second
IP Phone KEM to operate. This is because the second IP Phone KEM uses the first IP
Phone KEM to receive its power and communicate with the IP Phone.
Hot plug-in
Hot plug-in refers to the connection of one or more IP Phone KEMs to an active IP Phone. When
you connect an IP Phone KEM to an IP Phone that is already active, the IP Phone does not need to
be restarted. If there are other IP Phone KEMs already connected to the IP Phone, all the IP Phone
KEMs will reboot when you connect a new module.
Coldstart
You can press a sequence of keys (on the KEM) to trigger a cold start of a single IP Phone KEM,
or all IP Phone KEMs attached to the same IP Phone. The sequence must be performed while the
icons are flashing.
• To coldstart a single IP Phone KEM, press the following sequence of keys: 0, 12, 22, 10.
• To coldstart all attached IP Phone KEMs, press the following sequence of keys: 0, 12, 23, 11.
Figure 3 illustrates both coldstart sequences.

Controls and settings
When an IP Phone KEM is installed on an IP Phone 2002 or IP Phone 2004, the controls and
settings of the IP Phone control both the IP Phone and the IP Phone KEM. Use the Telephone
Options menu on the attached IP Phone to set the contrast and feature key labels of the IP Phone
KEM.
For more information about controls and settings (including the Telephone Options menu) for
your IP Phone, see the IP Phone 2002 User Guide (NN40050-107) or the IP Phone 2004 User
Guide (NN40050-108).
The enhanced KEM
Your system administrator must assign your KEM as an enhanced KEM in system programming
in order for you to have external line, target line and Hunt group appearances on your KEM
buttons. You can receive external calls only when KEM is operating in enhanced mode.
If you want more line buttons programmed on your KEM or more information on using Hunt

groups, see your system administrator.
Programming memory buttons
The default for KEM memory buttons is blank. You can program memory buttons on the KEM to
your personal preference with internal and external autodial numbers or features to give you touch
dialing or feature activation. If you are operating KEM in enhanced mode, you can pro gram
buttons for target line and Hunt groups as well. When you use enhanced mode, you can also
program duplicate buttons. For example, you can program more than one button for a particular
target line or external auto dialler.
Your KEM will be most effective if you use it along with these features:
•Camp-On (≤°¤)
• Transfer (≤‡‚)
• Priority Call (≤fl·)
