Table 3 VFC Firmware Extensions
DSPWare is stored as a compressed file within VCWare; you must unbundle VCWare to install
DSPWare into Flash memory. During the unbundling process, two default lists (the default file list
and the capability list) are automatically created, populated with default files from that version of
VCWare, and stored in VFC Flash memory. The default file list contains the filenames indicating
which files are initially loaded into DSP upon bootup. The capability list defines the set of CODECs
that can be negotiated for a voice call.
VFC management enables you to add versions of VCWare to Flash memory (download and
unbundle files), erase files contained in Flash memory, add files to the default file list and capability
list, and delete files from the default file lists and capability lists.
This section describes the following topics:
• Download VCWare
• Copy Flash Files to the VFC
• Unbundle VCWare
• Add Files to the Default File List
• Add CODECs to the Capability List
• Delete Files from VFC Flash Memory
• Erase the VFC Flash Memory
Download VCWare
To download software to your VFC, you need to do the following:
• Determine that the version of VFC ROM Monitor software is compatible with your installed
Cisco IOS image. VFC ROM version 1.2 requires Cisco IOS image 0.14.1 (1.6 NA1) or later.
VFC ROM Monitor version 1.2 can be made to work with Cisco IOS image 0.13 (or later) by
appending the suffix “.VCW” to the VCWare image stored in VFC Flash memory.
• Determine whether the VFC is in VCWare mode or ROM Monitor mode. The mode, whether
VCWare or ROM Monitor, determines how you download software to the VFC.
• Download the software using the appropriate procedure.
