This feature provides a software-based upgrade for existing AS5300/Voice gateways that use the earlier version TI C542-based voice feature cards. This upgrade was developed to provide feature parity and backwards compatibility with recently introduced capabilities for high density voice feature cards and IOS release 12.0(2)XH. This upgrade adds the following capabilities to existing TI 542-based systems:
The benefits of this release include:
You cannot mix DSPM-542s and DSPM-549s on the same voice carrier card.
This feature uses the AS53-6VOX DSP module with one of the following configurations:
For related information on this feature, refer to the following documents:

For descriptions of supported MIBs and how to use MIBs, see Cisco's MIB website on CCO at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
None
The following Cisco IOS Release images are required for 542 DSP modules:
Before you can configure your Cisco AS5300 to use VoIP, you must first complete the tasks listed below.
Step 1 Establish a working IP network. See Network Protocols Configuration Guide, Part I.
Step 2 Complete basic configuration for the Cisco AS5300 (that is, configure a host name, password, Ethernet interface, and ISDN PRI lines). For more information about these configuration tasks, see Cisco AS5300 Universal Access Server Software Configuration Guide.
Step 3 Install the VoIP card (VFC) into the appropriate slot of your Cisco AS5300 access server. Each VFC can hold up to five digital signal processor modules, enabling processing for up to 30 B channels with single-density DSPs or 60 B channels with double-density DSPs.
Step 4 Complete your company's dial plan and establish a working telephony network based on your company's dial plan.
Integrate your dial plan and telephony network into your existing IP network topology. For detailed procedures, see Cisco AS5300 Universal Access Server Software Configuration Guide.
Perform the following tasks to configure single-density voice for the Cisco AS 5300:
The following steps identify the voice cards in the system and determine whether the VFC is in VCWare mode or ROM monitor mode. The mode determines how you download software to the VFC. If VCWare is not loaded on the VFC, you can use the ROM monitor mode to download the VCWare. Otherwise, the VCWare mode is active.
| Step | Command | Purpose | ||
|---|---|---|---|---|
| 5300> enable Password: <password> 5300# | Enter enable mode (also called Privileged EXEC mode). Enter the password. You have entered enable mode when the prompt changes to 5300#. | ||
| 5300# show vfc <0-2> board | Determine the number of voice cards in the system, the slot number for each card, and the VFC mode (VCWare or ROM monitor) in which you are running. The VFC mode is indicated as follows:
or
Note the location and the mode type for each voice card. You will need this information when you upgrade the VCWare. |
Go to one of the following sections to continue the procedure to upgrade the VCWare:
or
Follow these steps to download new voice software if your voice card is running in VCWare mode. When downloading from a diskette, first copy the software from the diskette to a TFTP server.
 | Caution Erasing the VFC files can result in system outage or the corruption of your VFC board. Ensure that you have the correct software version on your TFTP server. |
| Step | Command | Purpose | ||
|---|---|---|---|---|
| 5300# erase vfc slot_number This will erase the contents of VFC Flash. Continue ?[y/n]: y This will take some time. Please, wait...vfc | See the Caution before this table. Erase the contents of the VFC Flash memory in the selected voice card. You must erase the previous files to load a new image. If this command fails, see "Replacing Firmware with VCWare in ROM Monitor Mode." | ||

Use TFTP to download the new VCWare to VFC Flash memory. In this example, slot 1 is the default. Note: Begin the destination image name with "vcw-" (all lowercase). Do not use any other character in front of vcw-; therefore, do not include a directory path at the beginning of the image name. Make sure that you enter the name correctly.

To check that you have successfully downloaded the software:
Step 1 Enter the show vfc slot_number directory command to verify that the VCWare is in the Flash memory. Only one filename appears. If this command times out, start over with "Identifying Voice Cards."
5300# show vfc 1 dir
Files in slot 1 VFC flash:

If you are having trouble downloading the voice card software in VCWare mode, see the following suggestions:
Step 1 Enter the show vfc slot_number board command to verify that the voice card is back up in VCWare mode.
5300# show vfc 1 board VFC board state is UP, vfc status VCWARE running(0x4) VFC board in slot 1 with 24 dsps 5300#
Step 2 Determine if the VFC ROM version you are running is version 1.1 or a later release.
5300# sh vfc 1 ver vcw
Voice Feature Card in Slot 1:
VCware Version : 3.0
ROM Monitor Version : 1.2
DSPware Version : 3.0
Technology : C542
Step 3 Enter the reload command to reboot the Cisco AS5300 so these changes take effect.
This section provides the following configuration examples:
