COMSPHERE 392xPlus Modems
Automatic Firmware Download
New releases may be available for the 392xPlus modems. The latest 392xPlus firmware is available at no charge from the Automatic Firmware Download Center. Refer to page A in the front of this document for contact information.
To download the firmware, your modem must be configured for dialing. Save your modem's current configuration to the Customer 1 or Customer 2 memory area, and load the Async Dial factory template (refer to Chapter 4, DCP Configuration, for more information about saving and changing configuration options).
If you have a DTE (terminal or PC) attached to your modem, informational messages appear on it when the modem connects. These messages show the amount of time the download will take. However, a DTE is not required.
The firmware download begins without any operator action. When the firmware download begins, the LCD displays download status messages with the data bank number, current block being loaded, and the total number of blocks.

If the modem connects at 14,400 bps, the download takes about 10 minutes. When the download completes, the modem resets itself and displays a normal status message (such as Idle:28.8).
Reload your saved configuration options from the Customer 1 or Customer 2 memory area.
Automatic Firmware Download Failure
If the firmware download is interrupted, the following screen appears.

This indicates that your modem is left in a state that can only be used to make or receive a call for download. To continue the firmware download, repeat the download process by directing the modem to dial the Automatic Firmware Download Center (refer to the Call Setup Branch section in this chapter for information about dialing a number using the DCP). If you are unable to complete the download, contact your service representative for assistance.
