Downloading over XMODEM
Download from XMODEM will provide some protocol checks during transfer,
whereas the serial download provides no check on the data transfer.
The following sequence shows you how to download a software image over
XMODEM.
1 Connect the serial cable to the serial interface port. For more information about the
default settings and pin-out of the serial port, see the Modules’ Installation Guides.
2 Enter the
system download xmodem
command:
After you press ENTER, the M770 ATM Switch will wait for data on the selected
serial interface port and transmission baud rate will default to 9600.
3 Start the transmission on the serial link.
Note:
Set up of new calls has priority over the XMODEM download, so on a busy
network it may be necessary to disconnect the M770 ATM Switch from the network in
order to achieve a successful download via the bootloader.
