B.3 Downloading the Application and Configuration
Software
New application software releases are distributed as *.img files, which are
downloaded to Vmux-2100 using the XMODEM protocol from the File System
menu of the boot software. Alternatively, you can download a new software
release via TFTP protocol, when the Vmux-2100 management software is already
running.
The TFTP protocol can also be used for uploading configuration files which contain
the Vmux-2100 database to the management station. Administrators can use this
capability to distribute verified configuration files to all other units which use the
similar configuration.
Downloading Application Files via XMODEM
Downloading application files using the XMODEM protocol is performed from the
File System menu of the boot software.
To download application file via XMODEM:
1. Configure your ASCII terminal or terminal emulation utility running on your PC
to the 115.2 kbps data rate.
2. Access the File System menu (see the Accessing the File System section above).
The File System menu appears (see Figure B-1).
3. From the File System menu, type 4.
Vmux-2100 displays the following message:
Select partition to download
4. Select the backup partition by typing its number, 1.
Vmux-2100 requires confirmation of the partition deletion:
The partition is full. Do you want to erase it (y/n)
5. Type Y.
Vmux-2100 responds with the following string:
Please start the XMODEM download.
6. Send the *.img file to Vmux-2100 using the XMODEM utility of you terminal
application.
Once the downloading is completed, Vmux-2100 saves the new release as an
active partition, the former active partition turns into backup, and the boot
sequence continues normally.
If a failure occurs during the download, the partially downloaded software is
erased. In this case, only active software is left in the Flash memory.
After the software upgrade has been performed, it will take several minutes for the
Vmux-2100 to begin operating again. This delay is due to the time the main module
requires to update all the voice modules.
