can also be found on the Resource Pack CD.
OverviewThe 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.

■ 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,

Windows machines, is typically available by an icon in the system tray.
Page 15
Configuring the pcXset Software15
You can also access the Volume Control program by clicking the Volume
Control icon (see Ta bl 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:
a Click Tools > Options. On the Advanced tab, enable the
Control
Mixer check box.
b Set the volume control to the value you want to use with pcXset.
c Click the Save Mixer Settings button.
d Set 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:
a Open the volume control window.
b Start the pcXset application and observe the volume control settings.
c Exit 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

that 3Com recommends that you use your system’s USB audio capabilities
rather than using sound card audio.
Audio Buffers Need
Adjusting
Audio Sounds
Distorted
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 > 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 choppy while on a conference call.
Description
You must configure some Ethernet cards to accept all multicasts to
improve audio quality.

“Full-Duplex Errors”, later in this guide, for more
information.
DTMF Tones Echo
Back to the
Analog
Line Card
The pcXset software cannot make external calls through any Analog Line
Card port, but calls to internal extensions are successful. Typically, the call
fails the first time, but succeeds if you click Redial.
Description
This error occurs when DTMF tones echo from the PC speakers back into
the microphone, causing the Analog Line Card to receive each outpulsed
digit twice.
Solution
Select Options > Display> Substitute For DTMF Tones. This option
replaces DTMF tones with clicks. The Analog Line Card ignores the clicks
when they echo back to the TLIM. You can also use headphones to
alleviate this problem.
Full-Duplex ErrorsFull-duplex audio is an audio card’s hardware ability to play and record
audio at the same time.
The following related message appears during an audio test or
microphone test:
The likely cause of this error is lack of full-duplex audio.
A similar message may appear in the log file:
ERROR: XXXXX [80042004H]
The likely cause of this error is lack of full-duplex audio.
Description
This error occurs when the pcXset software attempts to use the audio
card while another application is recording audio. It also happens when
the audio driver does not support full-duplex audio.
You can use Windows Sound Recorder to verify that the audio subsystem
supports full-duplex by running two Windows Sound Recorder

another application. If you get an error message, your audio card does
not support full-duplex audio.
Solution
Use a USB audio headset.
Incorrect IP Address
for the Call Processor
The following message appears during pcXset startup or after you click
Tes t on the IP Info tab of the Configuration Wizard.
This error has occurred in the Winsock subsystem. Please

A similar message may appear in the log file:
ERROR: XXXXX [80043002H]
This error has occurred in the Winsock subsystem. Please
check your IP configuration. Especially your NCP IP address.
Description
The Winsock call connect, used to determine the correct local interface
during Auto IP determination, received the error. This error normally
occurs if pcXset has an incorrect IP address for the Call Processor or
cannot connect to that Call Processor due to network problems.
Solution
1 Verify the Call Processor IP address. See “Configuring the pcXset
Software” for more information.
2 Verify the network connection by pinging the Call Processor from the
DOS prompt.

You can purchase additional licenses from your authorized NBX reseller.
■ Verify that you have connectivity with the Call Processor. Try to ping
the Call Processor IP address entered on the IP Info tab of the
Configuration Wizard, for example, 192.168.1.190. If you cannot
ping the Call Processor, then the pcXset software cannot
communicate with it either.
■ If you are attempting to use autodiscover, verify that Auto Discover
Telephones is enabled. In the NetSet utility, select System
Configuration > System Settings > System-wide.
■ Verify the NBX system MAC address. Select Configuration Wizard >
MAC Info > Reports > System Data.
■ Verify that you have selected the active network adapter on the MAC
Info tab. If you are unsure which device to select, use your computer’s
Control Panel to view device settings and verify the adapter driver that
