Download Software
The Download Software function sets parameters within the modem when transferring firmware
to one or more modems or when receiving firmware upgrades from a locally attached PC-based
controller. The latter is only performed by service representatives.
There are two selections under Download Software: Clone Remote and To Local via DTE. Clone
Remote is used to transfer an exact copy of the firmware currently stored in a 392xPlus modem to
either one or more remote 392xPlus modems or one or more DC-attached 392xPlus
modems.
When implementing a Clone Remote operation, the following is true:
• The Clone Remote function only operates properly if the remote modems are connected to
the local modem via a leased-line or an established dial-line network.
• The Clone Remote will not appear on the LCD if the modem is not configured for leased
lines and a dial-line connection does not exist.
For more information on Clone Remote operation, refer to Implementing a Clone Remote
Operation
later in this section.
The second selection appearing on the LCD is T
o Local via DTE. This function permits firmware
upgrades to be transferred to a 392xPlus modem. This type of download requires a locally attached
PC controller to be connected to the modem’
s DTE port as well as special download software.
Any
downloads using this selection are intended to be performed by service representatives only.
