Download Code
The Download Code function allows firmware to be
loaded into a modem from another modem or from a
DTE.
There are two selections under Download Code:
Clone to Remote and To Local via DTE. Clone to
Remote is used to transfer an exact copy of the firmware
currently stored in a 3821Plus modem to another
3821Plus modem. For this to occur, the modem must be
connected to the remote modem via a leased-line
network or an established dial-line network. If these
prerequisites do not exist, then this selection does not
appear on the LCD.
The second selection appearing on the LCD is To
Local via DTE. This function permits firmware upgrades
to be transferred to a 3821Plus 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 personnel
only.
Clone To Remote
This function allows you to transfer an exact copy of
the local modem’s firmware to a remote modem. Before
using Clone to Remote, perform the following:
•
Make sure the modems have an established dial
network connection using V.34, V.32terbo,
V.32bis, or V.32 modulation or a leased-line
connection using either V.34, V.32terbo, V.32bis,
or V.32 modulation.
•
Make sure the remote modem’s Access From
Remote configuration option is enabled.
•
Make sure the password (Remote Access Password
configuration option) is the same in both the local
and remote modems. (For an example of how to
change the password, refer to
To access Download Code from the Control branch,
make the following selections:
Press the
key until Download Code appears. Press
any function key to select Download Code.
Press any function key to select Clone to Remote.
At this point, if you do not want to continue this
process, abort the transfer by selecting any function key.
This returns the modem to the Top-Level menu.
However, to continue with the transfer, press the
key to display the Reprogram Remote selection.
WARNING
Pressing any function key now
begins the transfer to the
remote modem. This process
takes the communications link
out of service for
several minutes depending
upon the data rate of the link
(28,800 bps = 5 minutes). If the
Clone to Remote process is
interrupted, the remote modem
is left in a partially programmed
state in which its functional
capabilities are limited to those
required to initiate and
complete another download
attempt. If you cannot complete
a download, call your service
representative.
Press any function key (F1, F2, or F3) to begin the
transfer.
The local modem’s LCD displays Establish Remote,
indicating the modem is attempting to establish a
Remote Cloning Download session with the remote
modem.
If unsuccessful, the modem remains in the Download
Transfer mode. The LCD’s top line displays RemClone
Failed.
Correct the problem and attempt another download
from the local modem. If this fails, contact your service
representative.
As data banks are transferred, the local and remote
LCD’s bottom line displays the status of the download
process, and the number of records sent versus the total
number of records for that bank.
If the download is successful, the local modem
displays Remote Clone OK and the remote modem
displays Frmware Upgrade. If the download took place
over the dial network, the modems disconnect when the
download is complete.
To Local via DTE
This function is for use only by service personnel to
transfer new firmware to 3821Plus modems.
