Overview

High-density packet voice digital signal processor (DSP) modules (PVDM2) installed on the voice feature card convert voice and fax calls into IP packets or frames that can be transmitted as voice over IP (VoIP) over a variety of transport technologies on Cisco AS5350XM and Cisco AS5400XM universal gateways. The number of calls supported depends on the number of PVDM2 modules installed on the voice feature card, and the number of voice feature cards installed in the chassis.

The voice feature card supports a 64-channel PVDM2 (AS5X-PVDM2-64) module. You can install up to six AS5X-PVDM2-64 modules on each voice feature card. Table 6-1 describes the maximum number of channels supported by each AS5X-PVDM2-64 module and the maximum number of channels supported by a voice feature card with six AS5X-PVDM2-64 modules installed.

Note A Cisco AS5350XM or Cisco AS5400XM universal gateway with the maximum number of PVDM2 modules installed can take up to 6 minutes to boot from power-on to system ready.


For configuration details, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide. For information on voice and fax commands, see the Cisco IOS Voice Configuration Library for your Cisco IOS software release at Cisco.com.

You can install a voice feature card in any card slot of the universal gateway chassis. The voice feature card does not require external connections. (See Figure 6-1.)

Figure 6-1 Voice Feature Card

Restrictions for the Voice Feature Card

Voice feature cards are not compatible with universal port and dial-only feature cards. Voice feature cards should not be installed on any system that has universal port and dial-only feature cards. Table 6-2 describes the behavior of the Cisco AS5350XM and Cisco AS5400XM universal gateways depending on whether the voice feature card is present at power on.

Table 6-2 Voice Feature Card Support During Power On

Feature Cards Present at Power On
Feature Cards Supported

Voice feature card present at power on

Voice feature card only. Any universal port and dial-only feature cards present will not be operational until the voice feature card is removed and the system is rebooted.

Voice feature card not present at power on

Universal port or dial-only feature cards only. Any voice feature card installed later will not be operational until the system is rebooted.



Note If you plan to use voice feature cards, at least one voice feature card must be present when the universal gateway is powered on. More voice feature cards can be installed later.


Online Insertion and Removal of the Voice Feature Card

To remove a feature card without dropping any calls or connections, you will need to take the feature card out of service by using the busyout command to disable the feature card. The busyout command is executed on a per-feature card basis and will disable the card after waiting for the active services to terminate.

If there are active calls on the feature card after you execute the busyout command, wait for the calls to drop. To view the status of the termination process, use the show busyout command.


Caution The online installation and removal (OIR) of new cards should be done only during times of low CPU utilization, such as during maintenance.


Caution To avoid erroneous failure messages, remove or insert only one feature card at a time.

When you replace a feature card with a new feature card of the same type in the same slot, the system software recognizes the new feature card and brings up the interface automatically.

If you replace the existing feature card with a new feature card of a different type, you must reconfigure the system. For configuration details, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide. For information on voice and fax commands, see the Cisco IOS Voice Configuration Library for your Cisco IOS software release at Cisco.com.


Note To use the voice feature card, at least one voice feature card must be present when the universal gateway is powered on. More voice feature cards can be inserted later. See the "Restrictions for the Voice Feature Card" section for more information.


Removing the Voice Feature Card

To remove the voice feature card, follow these steps.


Note An example showing the output from each command is provided after the procedure. See the "Online Insertion and Removal Example for the Voice Feature Card" section.



Step 1 Determine which slot the feature card is in (see Figure 6-2 and Figure 6-3) by entering the show chassis slot command in privileged EXEC mode:

Router# show chassis slot


Note These commands are not valid for slot 0. Slot 0 is the motherboard.


Figure 6-2 Slot Numbering on the Cisco AS5350XM Chassis

Figure 6-3 Slot Numbering on the Cisco AS5400XM Chassis

Step 2 Initialize the software busyout procedure by entering the busyout command:

Router# busyout slot-number

Step 3 Check busyout status for the slot, by entering the show busyout command.

Router# show busyout slot-number


Timesaver You can use the clear voice dsp command to immediately disable active calls on the voice feature card.


Step 4 Verify that the OK/MAINT LED is off; this indicates that the feature card is offline and ready to be removed.


Note The OK/MAINT LED is green before you enter the busyout command. After you enter the busyout command, the LED changes to yellow. The LED turns off after all calls are disconnected and resources taken out of service, indicating that busyout is complete.


Step 5 Attach an ESD-preventive wrist strap.


Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001


Step 6 Loosen the two captive screws that secure the feature card to the chassis until each screw is free of the chassis. (See Figure 6-4 and Figure 6-5.)

Step 6 Check the OK/MAINT LED to verify that the card is working properly. For information about the voice feature card LED, see the "LEDs" section on page 7-1.


Note To use the voice feature card, at least one voice feature card must be present when the universal gateway is powered on. More voice feature cards can be inserted later. See the "Restrictions for the Voice Feature Card" section for more information.



Replacing PVDM2 Modules in the Voice Feature Card

The voice feature card contains six 80-pin SIMM sockets for PVDM2 modules, numbered 0 through 5. (See Figure 6-13.) Each socket can be filled with a single 80-pin PVDM2 module.


Note The voice feature card supports a 64-channel PVDM2 (AS5X-PVDM2-64) module.


Figure 6-13 PVDM2 Slot Locations

Orienting the PVDM2 Module During Installation

The PVDM2 modules are manufactured with a polarization notch to ensure proper orientation, and with alignment holes to ensure proper positioning. Figure 6-14 shows the polarization notch and alignment holes on a PVDM2 module. PVDM2 modules are installed with the connector edge down.


Caution To avoid damaging ESD-sensitive components, observe all ESD precautions. To avoid damaging the voice feature card, avoid using excessive force when you remove or replace PVDM2 modules.

Figure 6-14 PVDM2 Orientation

Removing PVDM2 Modules From the Voice Feature Card

To remove PVDM2 modules from the voice feature card, perform the following steps:


Step 1 Attach an ESD-preventive wrist strap.

Step 2 Find the appropriate PVDM2 slot on the voice feature card. (See Figure 6-13.)


Caution Handle PVDM2 modules by the card edges only. PVDM2 modules are ESD-sensitive components and can be damaged by mishandling.

Step 3 Remove one PVDM2 module at a time. To lift the PVDM2 module out of its socket, pull the locking spring clips on both sides outward and tilt the PVDM2 up, free of the clips.

Step 4 Hold the PVDM2 module by the edges with your thumb and index finger and lift it out of the socket. Place the removed PVDM2 module in an antistatic bag to protect it from ESD damage.

Step 5 Repeat Step 2 through Step 4 for each PVDM2 module you are removing.


Installing PVDM2 Modules in the Voice Feature Card

To install PVDM2 modules in the voice feature card, perform the following steps:


Step 1 Attach an ESD-preventive wrist strap.

Step 2 Find the appropriate PVDM2 slot on the voice feature card. (See Figure 6-13.)


Caution Handle PVDM2 modules by the card edges only. PVDM2 modules are ESD-sensitive components and can be damaged by mishandling.

Step 3 Hold the PVDM2 module with the polarization notch pointing toward the back of the voice feature card, with the connector edge pointing down. (See Figure 6-14.)


Caution It is normal to feel some resistance, but do not use excessive force to install the PVDM2 module into the socket, and do not touch the surface components. If the PVDM2 module does not fit easily into the socket, remove it and check the orientation of the alignment holes and polarization notch.

Step 4 Insert the PVDM2 module into the connector slot at approximately a 45 degree angle to the voice feature card. (See Figure 6-15.) Gently press the PVDM2 module down, using as little force as possible. When the PVDM2 module is properly seated, the socket guide posts fit through the alignment holes, and the connector springs click into place.

Step 5 Ensure that each PVDM2 module is straight and that the alignment holes (as shown in Figure 6-15) line up with the plastic guides on the socket.

Figure 6-15 Installing PVDM2 Modules in the Voice Feature Card

Step 6 Repeat Step 2 through Step 5 for each PVDM2 module.


Note When the voice feature card is installed and running, you can check that the PVDM2 modules are installed correctly by entering the show voice dsp summary command. If an installed PVDM2 module is missing from the output, try reseating the PVDM2 module.



Digital Signal Processor Firmware

Digital signal processor (DSP) firmware is automatically downloaded to the voice feature card from the Cisco IOS image when you boot the system for the first time, or when you insert a voice feature card while the system is operating. When you insert feature cards while the system is operating, the Cisco IOS image recognizes the cards and downloads the required firmware to the cards.

For more information on voice feature card firmware and upgrade options, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software Configuration Guide.
