Upgrading DSP Firmware
Clear a DSP
Use the clear voice dsp command in privileged EXEC mode to manually restart a DSP. This command
can be used to reset a DSP. This command causes the firmware that is configured for that DSP to be
downloaded to the specified DSP or range of DSPs. This command can be executed regardless of the
state of the DSPs. All active channels running on the DSP are prematurely terminated.
The following example shows a cold start on DSP 1 on slot 1:
AS5400# clear voice dsp 1/1
AS5400# Are you sure you want to clear voice dsp 1/1(Y/N)? Y
Upgrading DSP Firmware
With new systems, Cisco loads a Cisco IOS software-compatible version of DSP firmware into each
DSP. A map of the version or versions of DSP firmware copied to RAM for each DSP is stored in
NVRAM so that it is retained over power cycles.
Note You do not have to take any action to use the bundled version of DSP firmware with new systems.
You can acquire new DSP firmware from the Cisco Software Center in one of two ways:
•
•
When you have the new firmware, you can configure different firmware versions onto individual DSPs
or ranges of DSPs on a voice feature card. You can also configure different upgrade methods by using
the firmware upgrade command.
Do not store more than nine DSP firmware images in system flash memory. If you store more than nine
Note
DSP firmware images in system flash memory, the firmware upgrade command will fail. You will need
to delete at least one firmware image from the system flash memory and reboot the gateway to use one
of the remaining unbundled DSP firmware images.
Important Upgrade Commands
There are several commands you use to upgrade DSP firmware. For examples on using the commands,

Unbundled from Cisco.com. This is a more up-to-date version of DSP firmware released before the
next Cisco IOS release, or a special version of DSP firmware shipped with a new board. See the

Use the copy tftp flash filename command to copy any version of DSP firmware (no matter how it
is obtained) into system flash memory. You can store several versions of the DSP firmware in system
flash memory under different filenames.
Use the firmware location command in DSP configuration mode to transfer a specified version of
DSP firmware from system flash memory to the DSPs specified in DSP configuration mode.
