Console Download

You can use console download, which is a ROM monitor function, to download either a software image

or a configuration file over the voice gateway console port. After download, the file is either saved to

the mini-flash memory module or to main memory for execution (image files only).

Use console download when you do not have access to a TFTP server.

If you want to download a software image or a configuration file to the voice gateway over the console

Note

port, you must use the ROM monitor dnld command.

If you are using a PC to download a Cisco IOS image over the voice gateway console port at

Note

115,200 bps, ensure that the PC serial port is using a 16550 universal asynchronous transmitter/receiver

(UART). If the PC serial port is not using a 16550 UART, we recommend using a speed of 38,400 bps

or less when downloading a Cisco IOS image over the console port.

The following are the syntax and descriptions for the xmodem console download command:

xmodem [-c-y] destination_file_name

destination_

file_name

Follow these steps to run Xmodem:

Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error

checking to validate packets. Default is 8-bit CRC.

Optional. Sets the voice gateway to perform the download using Ymodem protocol. The

default is Xmodem protocol. The protocols differ as follows:

Xmodem supports a 128-block transfer size. Ymodem supports a 1024-block

transfer size.

Ymodem uses CRC-16 error checking to validate each packet. Depending on the

•

device that the software is being downloaded from, this function might not be

supported by Xmodem.

Name of the system image file or the system configuration file. In order for the voice

gateway to recognize it, the name of the configuration file must be voice
