This section contains new feature information for all Version 8.x.x releases.


Note There are no new features for the following NextPort SPE firmware versions: 8.11.1, 8.5.1, or 8.5.


New With Version 8.8.1 SPE Firmware

This section introduces new features for NextPort SPE firmware version 8.8.1.

NextPort Voice Tuning


Note To use the NextPort Voice Tuning feature, you must upgrade from the default NextPort SPE firmware code that runs with Cisco IOS software to NextPort SPE firmware release 8.8.1 or later. Release 8.8.1 can be downloaded from the Software Center on Cisco.com.


Voicecaps

Voicecaps are a means to tune voice services and potentially provide improved voice quality. The following parameters, among others, can be configured:

PSTN gains

IP gains

Dynamic attenuation

Comfort noise generation (CNG)

Minimum ERL—Switches off near-end talker clipping and poor echo canceller performance

Voice services on NextPort DFCs can be tuned with voicecap strings, which are configured and applied using the voicecap entry and voicecap configure commands.

For more information about voicecaps and how they are used, refer to the NextPort Voice Tuning Whitepaper on Cisco.com.

How to Configure NextPort Voice Tuning

This sections contains tasks to configure the NextPort Voice Tuning feature.

Downloading NextPort SPE Firmware (required)

Creating and Applying Voicecaps (required)

Verifying Voicecap Configurations

Troubleshooting NextPort Voicecaps

Downloading NextPort SPE Firmware

To download NextPort SPE firmware, use the following commands.

SUMMARY STEPS

1. enable

2. configure terminal

3. spe slot/spe-begin slot/spe-end

4. firmware location system: firmware

5. end

6. copy running-config startup-config

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

spe slot/spe-begin slot/spe-end

Example:

Router(config)# spe 1/0 1/17

Downloads SPE modem code to all modems in a particular slot (that is, all modems on a feature card containing eighteen 6-port modem modules).

Enters SPE configuration mode.

Step 4 

firmware location system: filename

Example:

Router(config-spe)# firmware location flash:np.8.8.1.spe

Downloads SPE modem code to Flash memory.

Step 5 

end

Example:

Router(config-spe)# end

Completes the download and exits SPE configuration mode.

Step 6 

copy running-config startup-config

Example:

Router# copy running-config startup-config

Copies the configuration from running RAM into NVRAM.

The download occurs when the modems become available and the display shows the SPE firmware upgrade option defined (default: busyout).

The spe command generates NVRAM modem download and configuration file entries.

Note If the configuration is not saved as described above, download of the firmware specified with the spe command will not occur after the next reboot.

For detailed information on the spe command, refer to the Cisco document
SPE and Firmware Download Enhancements.

Creating and Applying Voicecaps


Note To create and apply voicecaps, it is required that you contact Cisco Technical Response Center (TAC).


The steps in this section allow you to configure a voicecap on a single voice port. Although voicecaps can be used to configure any of the voice service parameters, voicecaps are primarily used to configure only those parameters that do not have associated Cisco IOS commands.

The voicecap entry name string command configures NextPort SPE firmware through voicecap strings in global configuration mode. This command allows you to assign values to specific registers. Voicecaps are applied to specific voice ports at system startup.

The voicecap configure name command applies a voicecap on NextPort platforms in voice-port configuration mode.

Restrictions

Voicecaps are configured in global configuration mode. A maximum of five voicecap entries can be defined.

Applying a voicecap is possible only in voice-port configuration mode. Once applied to a voice port, the voicecap affects all calls associated with that voice port.

An SPE image capable of voice tuning must be used in conjunction with a Cisco IOS release 12.3(1)M or later

SUMMARY STEPS

1. enable

2. configure terminal

3. voicecap entry name string

4. voice-port slot/port:D

5. voicecap configure name

6. exit

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

Enter your password if prompted.

Step 2 

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3 

voicecap entry name string

Example:

Router(config)# voicecap entry EXAMPLE v0 = 0

Creates a voicecap.

The name argument is a word that uniquely identifies this voicecap.

The string argument is a string of characters composed of a series of voicecap register entries, similar to a modemcap. Each entry is of the form vINDEX=VALUE, where INDEX refers to a specific V register, and VALUE designates the value to set that V register to.

The example creates a simple voicecap string named "EXAMPLE v0 = 0."

Note Contact Cisco TAC to assist in designing a voicecap configuration.

Step 4 

voice-port slot/port:D

Example:

Router(config)# voice-port 3/0:D

Enters voice-port configuration mode on the selected slot and port.

Step 5 

voicecap configure name

Example:

Router(config-voiceport)# voicecap configure EXAMPLE v0 = 0

Applies a voicecap.

The name argument designates which of the newly created voicecaps to use on this voice port. This character value must be identical to the value entered when you created the voicecap entry. In this case, the value is "EXAMPLE v0 = 0."

Note To configure multiple voice ports, repeat the voice-port slot/port:D and voicecap configure name commands for each voice port.

Step 6 

exit

Example:

Router(config-voiceport)# exit

Exits voice-port configuration mode and completes the configuration.

Verifying Voicecap Configurations

Use the following show command in privileged EXEC mode to verify your configuration.

SUMMARY STEP

1. show voice port

DETAILED STEP


Step 1 show voice port

Use this command to display configured voicecaps, for example:

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC Web Site, you can open a case online by using the TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the center, please have available your service agreement number and your product serial number.
