							Appendix B  Voice Quality Manager
Introduction
The Voice Quality Manager (VQM) is a software package that resides on the MC95XX. VQM enables a set of 
features for Voice over WiFi (VoWiFi) calls, and a sub-set of those features for cellular line calls. The VQM user 
interface is designed to be intuitive and easy to use, so complex tasks such as enabling the Acoustic Echo 
Canceller (AEC) while a call is in progress are done with very little or no user intervention.
Features
The VQM software:
•Improves the voice transmission quality without using additional battery power.
•Turns on the AEC for VoWiFi calls automatically, without user intervention.
•Prioritizes the outgoing audio IP packets.
•Provides user-selectable audio modes (speakerphone and handset) with a single tap of the VQM icon. A 
VQM icon in the title bar of the device indicates the audio mode currently in use.
•NDIS 5.1 compliant.
Enabling VQM
To enable VQM:
1.Ta p  Start > Programs > File Explorer.
2.Navigate to the Windows folder.
3.Locate the file VQMAudioNotify.
4.Tap the filename to enable VQM.

Audio Modes
The MC95XX can be in any one of the seven different audio modes. The mode is visually indicated by the VQM 
icon on the title bar.

The VQM icon indicates that the device is in speakerphone mode without Acoustic Echo Cancellation (indicated by 
the gray VQM icon). The audio modes and their corresponding VQM title bar icons are:
Changing Audio Modes
Depending upon the audio mode being used, the mode can be changed by tapping the VQM icon in the title bar. 
The audio mode can only be changed only while the user is on a call.

							Using the Interfaces B - 3
The table below lists the current audio mode and the subsequent audio mode after tapping the VQM icon.
If the audio mode is set to speakerphone and the user taps the VQM icon, the audio mode changes to handset.
If the user is using a Bluetooth headset, tapping the VQM icon un-pairs the Bluetooth headset from the device 
causing the audio to be routed to the default mode. In VQM 2.5, there is no way to go back to the Bluetooth 
headset using the VQM icon if it is un-paired The only way to reconnect the Bluetooth headset to the device is by 
using the BTExplorer application.
If the user taps the VQM icon when a wired headset is connected to the mobile device, the audio mode does not 
change. The audio continues to get routed to the wired headset.
If the user taps the VQM icon while not on a call there is not change to the audio mode.
Tap and hold the VQM icon in the title bar to display a notification dialog box that contains:
•AEC: The Acoustic Echo Canceller status
•DSCP Marked Packets: The number of outbound voice packets that have been recognized and marked as 
high priority by VQM.
•VQM Version: The VQM version number.

Voice Packet Prioritization
IP soft phones transmit voice packets in the same manner as any other application that sends data over the 
network. On a network with different types of traffic, voice packets are given the same priority as any other traffic, 
and therefore may be subject to delays.
WiFi Multi-media (WMM) is a solution to this problem. WMM is a specification that supports prioritizing traffic, and 
“higher-priority” packets can be given preferential treatment.

							B - 4 MC9500-K Mobile Computer User Guide
To make use of WMM, the devices that generate traffic must mark their packets as high or normal priority in a field 
in the IP packet called Differentiated Services Code-Point (DSCP). The wireless infrastructure, which must be 
configured to support WMM, gives a higher priority to packets that have been marked as high priority through 
DSCP marking by the devices that generate traffic.
VQM detects if there is an ongoing Voice over WiFi (VoWiFi) call, and if so, marks outgoing voice packets (Only 
outgoing voice packets can be marked. The incoming voice packets have already been through the network, so it 
makes no sense to mark them.) as high-priority using DSCP. This enables WMM-compatible wireless infrastructure 
to treat the voice packets preferentially. This results in fewer delays for voice packets, which in turn improves the 
call quality.
Limitations
•There is no VPN support in VQM.
•Only the Avaya softphone is currently supported.
Acoustic Echo Cancellation
Acoustic Echo occurs during a voice call when the audio from the earpiece enters the microphone of the same 
device. This results in the person at the other end hearing back a delayed version of his/her own voice (“Echo”). 
Needless to say, “Echo” is not desirable, and needs to be suppressed. This is the functionality performed by the 
Acoustic Echo Canceller (AEC). There are two approaches to suppressing the Echo:
•Turn the Acoustic Echo Canceller (AEC) on permanently. This approach is not very efficient because the 
device consumes more power when the AEC is on.
•Turn the Acoustic Echo Canceller (AEC) on only when there is an ongoing call.
VQM follows the second of the two approaches mentioned above.
VQM automatically turns on the Acoustic Echo Canceller (AEC) when the mobile device is in a VoWiFi call. When 
the call is terminated, VQM turns the AEC off. Note that the AEC is turned on for speakerphone and handset 
modes and does not get turned on for wired headset and Bluetooth headset modes. The AEC is not required for 
wired headset because the audio volume is quite low (because of the proximity of the earpiece to the ear), and 
therefore it is very unlikely for the audio from the earpiece to go in to the mouthpiece. Bluetooth headsets typically 
have an Echo Canceller built in. Turning the AEC on only while on a call saves battery power, compared to leaving 
the AEC turned on permanently.
The AEC is not turned on for Cellular calls because the WWAN phone application has a built-in echo canceller.
Disabling VQM
To disable VQM perform a warm boot. 
						

							Appendix C  Keypads
Introduction
The MC9500-K offers four types modular keypad configurations:
•Alpha Primary
•Alpha Numeric
•Calculator Numeric
•Telephony Numeric. 
						

							C - 2 MC9500-K Mobile Computer User Guide
Alpha Primary Keypad
The Alpha Primary keypad produces the 26-character alphabet (A-Z, both lowercase and uppercase), numbers 
(0-9), and assorted characters. The keypad is color-coded to indicate which modifier key to press to produce a 
particular character or action. The keypad default is lowercase alpha characters. See Table C-1 for key and button 
descriptions and Table C-9 on page C-18 for the keypad’s special functions.
