Overview The pcXset PC Telephone is a software application that enables a user’s
computer to have the same features and functions as an NBX Business
Telephone. Using the pcXset software is similar to using an NBX Business
Telephone except that the telephone has a handset while the pcXset
software requires a headset with a microphone connected to the client
computer. You use the computer’s mouse and keyboard to operate the
pcXset controls.
3Com recommends that you use a USB headset with your computer. Do
not use the computer’s built-in speaker and microphone due to sound
quality issues.

6GETTING STARTED WITH PCXSET
The pcXset software can accept calls only when both the client computer
and the pcXset software are running. However, voice mail messages are
received and stored on the NBX system even if the pcXset computer is not
running.
The pcXset Help contains instructions for using the application. For
detailed instructions on using the pcXset software, select Contents from
the Help menu.
The NBX Business Telephone Guide has similar instructions, except for the
obvious differences between using the controls of a physical telephone
and the controls of a software program.

■Prevent Machine from Entering Standby Mode — (See Figure 2)
A call that comes in to the pcXset application when your computer is
in standby mode is transferred to voice mail. This setting is enabled by
default to prevent your computer entering standby mode.
■Substitute for DTMF tones — (See Figure 2) Check this box to hear
a “click” sound when you dial using pcXset software instead of the
normal DTMF tone that you hear when dialing with a regular

Configuring the pcXset Software 13
telephone. This substitution makes the pcXset software sound more
like a PC application.
Configuring Network
Settings
In the Network tab (Figure 5), you can customize or adjust the network
settings that you applied in the Configuration Wizard.
Figure 5 Options Dialog Box - Network Tab

14 GETTING STARTED WITH PCXSET
Configuring
Advanced Settings
Use the Advanced tab (Figure 6) to adjust your audio parameters and
communications strategy.
Figure 6 Options Dialog Box - Advanced Tab
■Tone Volume — Allows independent volume control of dial tone,
dialing, and DTMF tone sounds (that is, telephone audio tones) which
are generated when you press digits to dial a telephone number.
■Control Mixer — A mixer program controls settings such as the
amplification level of the microphone, computer volume, CD device,
and wave play. The mixer program, which is called Volume Control on
Windows machines, is typically available by an icon in the system tray.

Configuring the pcXset Software 15
You can also access the Volume Control program by clicking the Volume
Control icon (see Tab l e 1) in the NBX pcXset Configuration Wizard.
You can set and save a set of mixer state values for use with the
pcXset application. Each time you start the pcXset application, it uses
these saved values instead of the Windows default values. To set and
save the mixer values for pcXset, open the Volume Control window,
start the pcXset application and:
aClick Tools > Options. On the Advanced tab, enable the
Control Mixer check box.
bSet the volume control to the value you want to use with pcXset.
cClick the Save Mixer Settings button.
dSet the mixer amplification levels back to the values you want to use
as the Windows default values.
When the pcXset application is active, it uses the saved mixer
amplification levels. When pcXset is not the active window, it uses the
Windows default values.
To verify this:
aOpen the volume control window.
bStart the pcXset application and observe the volume control settings.
cExit from the pcXset application and observe that the volume control
mixer settings change from the values used by the pcXset application
to the Windows default values.
■Share audio hardware — Enable this selection for the pcXset
software to share the audio hardware recording channel. If you do not
enable this, you must close the pcXset application before any other
applications can use the audio hardware recording channel.
■Shared shutdown delay (sec.) — If you have chosen to share the
audio hardware and find that the pcXset application is cutting off the
audio, increase this value. For example, increase the value if the tones
are distorted when you dial a telephone number. The default value for
this setting is 2 seconds.
CAUTION: Increasing the value too much can also prevent the pcXset
application from playing tones properly or prevent other applications
from using the shared audio hardware, which could result in audio
sharing conflicts. See “Troubleshooting” for more information.
■Force Layer 3 (IP) — Select Force Layer 3 to force the pcXset
software to use Layer 3 IP addressing to communicate with the NBX

16 GETTING STARTED WITH PCXSET
system. When you use Layer 3, the pcXset application requires the IP
address of the NBX system. You specify this setting using the pcXset
Configuration Wizard, or using the Network tab of the Options dialog
box.
When you use Layer 3, you must also specify the version of your NBX
software.
■Accept All Multicasts — Some Ethernet cards do not fully support
selective multicasting communication. Select this option if you are
experiencing problems with conference calls or internal or external
paging.
■Delay and Multiplier — The size of the audio buffer pool is a product
of Delay and Multiplier. Higher multipliers and lower delays generally
produce an optimal audio setup. Higher overall values may improve
audio quality for slower machines at the expense of a small
communications delay. Lower overall values improve audio
responsiveness, but may result in some audio break-up for slower
machines.
■PC Speaker Audio Warning Setup — These values determine at
which frequency and for how long your PC plays a sound when there
is an incoming call. Press Test to hear a sample tone.

Editing the Access Button Labels and Tooltip Pop-ups 17
Editing the Access
Button Labels and
Tooltip Pop-ups

that 3Com recommends that you use your system’s USB audio capabilities
rather than using sound card audio.
Audio Buffers Need
Adjusting
Choppy audio occurs during telephone conversations or during the audio
test in the Configuration Wizard, or there are delays in audio playback
during telephone conversations.
Description
This problem is caused by incompatible audio buffer size settings.
Solution
Audio buffer size settings are expressed as two values: Delay and
Multiplier. The product of these numbers represents the overall size of the
buffer pool. Lower values for these numbers reduce echo delay. Higher
values increase audio quality. Change these values in any of these ways:
■Select Configuration Wizard > Audio > Audio Configuration
■Select Configuration Wizard > Mic > Audio Configuration
■Select Options > Advanced
These numbers depend on your computer hardware and operating
system. Experiment with different value combinations to see how low you
can adjust the product of the delay and multiplier and still achieve good
audio quality.
Audio Sounds
Distorted
Audio sounds choppy while on a conference call.
Description
You must configure some Ethernet cards to accept all multicasts to
improve audio quality.
Solution
1Run the pcXset software.
