Downloading and Broadcasting
Firmware
This chapter describes file transfers using FTP and downloading
firmware upgrades to application modules.
A major feature of the AS2000 architecture is the capability of
changing the personalities of AS2000 application modules by
downloading firmware upgrades to the module’s flash RAM. This
method may be used to upgrade an NCM card or the application
modules which the NCM manages.
Four types of firmware downloads are supported by the NCM Craft
interface:
• Local download: uses FTP to copy new firmware to the RAM
disk on the NCM and then stores it to local flash to upgrade
the NCM.
• Broadcast download: uses FTP to copy new firmware to the
RAM disk on the NCM, then broadcasts the firmware to one or
more other modules in the local node.
• Remote download: uses FTP to copy new firmware to the RAM
disk on the NCM, then directs the firmware to a remote NCM.
The firmware may then be targeted or broadcast to other
modules in the same node as the remote NCM.
• Targeted Download: uses FTP to transfer files to RAM disk and
then retransmission to a specific card.
