Console Download Appendix A Using the ROM Monitor 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. Note If you want to download a software image or a configuration file to the voice gateway over the console port, you must use the ROM monitor dnld command. Note If you are using a PC to download a Cisco IOS image over the voice gateway console port at 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. Command Description The following are the syntax and descriptions for the xmodem console download command: xmodem [-c-y] destination_file_name c Optional. Performs the download using 16-bit cyclic redundancy check (CRC-16) error checking to validate packets. Default is 8-bit CRC. y 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. destination_ Name of the system image file or the system configuration file. In order for the voice file_name gateway to recognize it, the name of the configuration file must be voice gateway_confg. Follow these steps to run Xmodem: Step 1 Step 2 Move the image file to the local drive where Xmodem will execute. Enter the xmodem command.
