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.

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.

You can only download a software image over the serial interface.
To download over serial interface, use the following steps:
1

Connect the cable to the serial interface port to download the software image.

2

Enter  the

system download serial

command: 

After you press ENTER, the M770 ATM Switch will wait for data on the serial 
interface.
