First Published: February 27, 2006

Last Updated: July 11, 2008

The High-Density Packet Voice Feature Card for Cisco AS5350XM and AS5400XM Universal Gateways (product number AS5X-FC) feature supports up to six high-density packet voice/fax digital signal processor (DSP) modules (product number AS5X-PVDM2-64), increasing the density of the feature card to 384 low-complexity or 192 medium-complexity or 144 high-complexity VoIP calls.

The High-Density Packet Voice Feature Card for Cisco AS5350XM and AS5400XM Universal Gateways (referred to here as the High-Density Packet VFC) with one to six PVDM2-64 modules can provide the correct number of DSPs depending on the codec type needed and Cisco AS5350XM and Cisco AS5400XM trunk configuration.

You can select the minimum number of PVDM2-64 modules depending on the voice channels currently needed, and then add PVDM2-64 modules as requirements expand. The High-Density Packet VFC supports T1/E1 and CT3 configurations.

The High-Density Packet VFC is designed to work with basic software configurations on Cisco AS5350XM and Cisco AS5400XM platforms without requiring specific configuration changes. However, there are some changes to existing command-line interface (CLI) commands that enable you to customize and troubleshoot your configuration to improve performance. These commands are described in the "Command Reference" section on page 28.

Restrictions for the High-Density Packet Voice Feature Card

Before you can run the High-Density Packet VFC for Cisco AS5350XM and AS5400XM Universal Gateways, you must install an IP Plus image (minimum) of Cisco IOS Release 12.4(9)T or a later release.

Software echo cancellation is the default configuration—G.168-compliant echo cancellation is enabled by default with a coverage of 128 milliseconds (ms). Hardware echo cancellation is not available.

The High-Density Packet VFC uses only PVDM2-64 Packet Fax/Voice DSP modules.

Global System for Mobile Adaptive Multi-Rate Narrow Band (GSMAMR-NB) codec support is available only with H.323 and Session Initiation Protocol (SIP) as call control protocols. When DSPware supporting the GSMAMR-NB codec is used, all DSPs on all VFCs in the Cisco AS5350XM or AS5400XM must run the GSMAMR-NB DSPware.

Skinny Client Control Protocol (SCCP) is not supported.

To use High-Density Packet VFCs in your gateway, you must have at least one High-Density Packet VFC installed prior to bootup. Additional High-Density Packet VFCs can be installed later.

A mix of High-Density Packet VFCs and NextPort Dial Feature Cards (NP DFCs) is not supported. If a High-Density Packet VFC is installed in a Cisco AS5350XM or Cisco AS5400XM with a NextPort DFC running, you must reboot the system to support the High-Density Packet VFC, and the NextPort DFC will be powered down. That is, if a High-Density Packet VFC is present during bootup, dial-only and universal port cards will not operate.

---

Note If no AS5X-FC is installed during bootup, the gateway will support only dial-only or universal port cards. If you want to use an AS5X-FC, you must install the card and reboot the system.

Configuring the GSMAMR-NB Codec for the High-Density Packet Voice Feature Card

This section provides information about the following:

•Overview and Restrictions for the GSMAMR-NB Codec, page 8

•GSMAMR-NB Codec Compliance with RFC 3267, page 9

•How to Configure the GSMAMR-NB Codec on the High-Density Packet Voice Feature Card, page 10

Overview and Restrictions for the GSMAMR-NB Codec

The Adaptive Multirate Narrow Band (AMR-NB) codec is a high complexity multimode codec that supports eight narrowband speech encoding modes with bit rates between 4.75 and 12.2 kbps. The sampling frequency used in AMR-NB is 8000 Hz and the speech encoding is performed on 20 ms speech frames. Therefore, each encoded AMR-NB speech frame represents 160 samples of the original speech.

The AMR-NB codec was originally developed and standardized by the European Telecommunications Standards Institute (ETSI) for Groupe Speciale Mobile (GSM) cellular systems. and chosen by the Third Generation Partnership Project (3GPP) as the mandatory codec for third generation (3G) cellular systems.

1 Used for Silence Indication Detection (SID) frames.

How the AMR-NB Codec Works

The multirate encoding (or multimode) capability of AMR-NB is designed for preserving high speech quality under a wide range of transmission conditions. Unlike other codecs, the AMR-NB codec can adapt to different bit rates (see Table 1) based on channel conditions during the call.

To perform mode adaptation, the decoder (speech receiver) sends a signal to the encoder (speech sender) to indicate which new mode it prefers. This mode-change signal is called codec mode request (CMR). Because speech is sent in both directions between the two ends in most sessions, the mode requests from the decoder at one end to the encoder at the other end are sent in a piggyback form over the speech frames in the reverse direction; there is no out-of-band signaling needed for sending CMRs. The Cisco AS5400XM and Cisco AS5350XM cannot initiate CMRs and received CMRs can be processed. For more information about AMR-NB codecs, see RFC 3267.

Feature Limitations or Restrictions

•All the DSPs in the system must be upgraded with the GSMAMR-NB DSPware.

•The following message is displayed when an upgrade takes place if a version of DSPware other than the recommended version is uploaded:

WARNING: Recommended GSM AMR-NB supported DSPware for this Cisco IOS image is X.Y.Z 
Where X.Y.Z changes depending on the Cisco IOS image that is used by the customer.

This warning has no impact on the firmware upgrade and calls can be brought up with a version of DSPware that is not the recommended version.

GSMAMR-NB Codec Compliance with RFC 3267

GSMAMR-NB codec support is compliant with RFC 3267. Specifications for RFC 3267 are supported by the High-Density Packet Voice Feature Card:

•The Cisco AS5350XM and Cisco AS5400XM do not initiate CMRs. However, these platforms can process the received CMRs.

•RFC 3267 allows for the sending of redundant voice frames with the same sequence number and time stamp. The Cisco AS5350XM and Cisco AS5400XM platforms do not send redundant packets, but they can receive redundant frames. When redundancy is used, RFC 3267 allows for different compression modes to be used for redundant frames. The standard recommends that when two redundant frames are received accurately, the frame with the lower compression (highest bit rate) be used. The Cisco AS5350XM and Cisco AS5400XM instead use the frame that is first received.

•The following apply to the codec gsmamr-nb command used to configure the GSMAMR-NB codec:

–Cisco AS5350XM and Cisco AS5400XM do not support any of the parameter changes after the call is up.

–Support is provided for both octet-aligned and bandwidth-efficient frame formats.

–Support is provided for all eight modes of AMR-NB codec.

–The gateway can change to any mode at any time, which translates to mode-change-period of 20 ms and mode-change-neighbor value of 0.

–CRC is supported.

–Only supported value for maxptime and ptime arguments is 20 ms.

–Robust sorting and interleaving are not supported.

•The only supported value for the channels argument is 1.

Using Online Insertion and Removal to Replace the High-Density Packet Voice Feature Card

High-Density Packet VFCs are hot-swappable and replaceable (using online insertion and removal [OIR]). However, you should complete the following steps before removing the card:

SUMMARY STEPS

1. enable

2. busyout slot

3. show busyout slot

4. show chassis slot slot

5. clear voice dsp {channels | error} [slot[/dsp][/channel]] [slot[/dsp][/channel]]

6. Remove the High-Density Packet VFC from the slot.

7. Insert the new High-Density Packet VFC in the slot.

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables privileged EXEC mode. •Enter your password if prompted.
Step 2	busyout slot Example: Router# busyout 2	Disconnects calls on the card. •The slot argument identifies the location of the High-Density Packet VFC in the chassis.
Step 3	show busyout slot Example: Router# show busyout 2	Shows information that indicates when busyout is complete and all calls are disconnected. •The slot argument identifies the location of the High-Density Packet VFC in the chassis. •The associated configuration of the High-Density Packet VFC is automatically removed from the system configuration.
Step 4	show chassis slot slot Example: Router# show chassis slot 2	During the busyout process, the show chassis slot displays the state of the High-Density Packet VFC as DFC_S_REMOVING. •The slot argument identifies the location of the High-Density Packet VFC in the chassis. •Confirm the completion of the busyout by repeating the show chassis slot slot command until the status changes to DFC_S_REMOVED.
Step 5	clear voice dsp {channels | error} [slot[/dsp][/channel]] [slot[/dsp][/channel]]	(Optional) Forces a busyout of all calls on a channel. Use this command to forcefully busyout any remaining calls on specific channels, slots, or DSPs. •channels—Clears DSP calls on a specific channel or a range of channels. •errors—Clears DSP error statistics. •/slot—(Optional) Specifies either a single slot or the first slot in a range. To specify a range of slots, you can enter a second slot in the syntax of this argument. The second slot specifies the end of the range. All slots in the range are affected by the command. •/dsp—(Optional) Specifies either a single DSP on the slot or the first DSP in a range. To specify a range of DSPs, you can enter a second DSP in the syntax of this argument. The second DSP specifies the end of the range. All DSPs in the range are affected by the command. •/channel—(Optional) Specifies either a single channel on the DSP or the first channel in a range. To specify a range of channels, you can enter a second channel in the syntax of this argument. The second channel specifies the end of the range. All channels in the range are affected by the command.
Step 6	Remove the High-Density Packet VFC from the slot.	The High-Density Packet VFC is physically removed from the chassis.
Step 7	Insert the High-Density Packet VFC in the slot.	When the High-Density Packet VFC is reinserted in the chassis, the card is automatically detected and activated.
