Voice/Network Statistics reports
The Voice/Network Statistics feature provides you measurement data to resolve
voice quality issues within your network. You can view the measurement data
through the SAT interface in the form of reports, which is helpful to
troubleshoot threshold events (packet loss, jitter, and round trip delay) duringcalls.
The media processor board gathers data on a per call basis, based on
SAT-administered threshold events that have been exceeded. Then it supplies this
data to Communication Manager that in turn generates the voice/network
statistics reports. These reports help you to determine the cause of a voice
quality issue.
The SYSTEM PARAMETERS IP-OPTIONS form and IP INTERFACES form provide information
on Voice/Network Statistics. In the IP-OPTIONS SYSTEM PARAMETERS form, a Voice/
Network Stats field is added to the System-Parameters IP-Options Report and in
IP INTERFACES form, the VOIP/Network Thresholds fields are added to the
IP-Interfaces Report.
Voice/Net Stats Field on System-Parameters IP-Options Form
The Enable Voice/Network Stats? field in the change system-parameters ip-options
form, enables/disables Voice/Network Statistics at the system level. When the
Enable Voice/Network Stats? is set to y, Voice/Network Statistics for threshold
events are recorded on the media processor boards. However, Voice/Network
Statistics feature has to be turned on at the media processor board level as
well.
Thresholds Fields on IP-Interface Form
The change ip-interface form includes Voice/Network thresholds at the media
processor board level. The threshold fields and their default values are
displayed only when the value in the Enable Voice/Network Stats? field on the
change system-parameters ip-interface form is y and a valid TN2302 or TN2602
media processor board is used, and has also been entered on the change meas-sel
media-processor form.

Field Description
------------ -----------
Enable VoIP/ Enables/disables the recording of Voice/Network Statistics at a
Network single media processor board level (applies to both TN2602
Thresholds? boards, if duplicated).
Packet Loss Unacceptable packet loss coming into the administered media
(%) processor board.
Note: "xxx" indicates 100% packet loss.
Jitter (ms) Unacceptable jitter coming into the media processor board at
which point data is captured to send up to Communication Manager
RT Delay Unacceptable elapsed time for a packet to reach remote location
(ms) and revert. (Round Trip Delay

Status Station report
A page on Voice Statistics is added to the Status Station report. This page
allows you to view real time Voice Statistics for the calls in progress, which
may or may not exceed the administered Voice/Network thresholds.

Summary Voice/Network Statistics reports
The summary reports can be obtained for yesterday-peak, today-peak, or last-hour
interval. The summary reports provide measurement data on the calls during the
peak hour per board over a 24-hour period.
Summary Jitter report
The summary jitter report summarizes up to five worst jitter calls for the
corresponding peak hour for a given media processor board in the network region.

Type list measurements ip voice-stats summary data ['yesterday' | 'today' | 'last-hour'] and press Enter.

Change measurement selection forms
When you specify a specific network region or media processor in a list
measurements ip voice-stats report and that network region or media processor is
included in the ch meas-selection form, then the system shows a list measurement
report, otherwise the following error message is displayed: Not a measured
resource. For more information, refer to Voice/Network Statistics reports.
There is a major inter-dependency between ch meas-sel media-processor form and
the ip-interface form. For example, you have to have the media processor on both
of these forms in order to collect data. In addition, the board has to be
Voice/Network Statistics-enabled and Voice/Network Statistics-capable
(correct firmware version on the media processor board). You cannot enter Y in
the Enable Voice/Net Stats? field unless the board location has been entered
on the ch meas-sel media-processor form and that media processor's firmware is
Voice/Network Statistics-capable. For more information, refer to Thresholds
Fields on IP-Interface Form
--------------------------------------------------------------------------------
Command
To display the NETWORK REGION MEASUREMENT SELECTION report:
Type change meas-selection network-region [schedule]and press Enter.
--------------------------------------------------------------------------------
Command
To display the MEDIA PROCESSOR MEASUREMENT SELECTION report:
Type change meas-selection media-processor [schedule]and press Enter.
The validations for the command are as follows:
- If media processor board is not a TN2302 or TN2602, do not allow it on this
form. Communication Manager performs this validation.
- If TN2302/TN2602 is physically inserted, perform a capabilities exchange to
confirm that the board can support this feature. Communication Manager performs
this validation.
- When a media processor board is removed from the ch meas-sel media-processor
form, Communication Manager must verify that the Voice/Net Stats feature has
been disabled on the ip-interface form, otherwise the following error message is
displayed: Must first disable voice/net stats on ip-interface form. Also, you
must check the same, that is, Voice/Net Stats feature is disabled on the
ip-interface form, with duplicated TN2602 media processor boards, if your are
going to/from duplicated, simplex or load balanced media processor boards.
- In addition, if a board location or network region is moved or deleted, all
previous data for that board/network region and measurement hour is lost. If you
attempt to move a network region/media processor board from one position to
another, the following warning message is displayed: Moving a board/NR from one
location to another will result in the loss of existing data.
