Firmware Update/Upgrade The 2864 series modem uses 4Mbit flash EPROM(s). The firmware in flash EPROM can be updated by uploading a file from the locally connected DTE. There is no need to open the modem case or use a programming device. The firmware is distributed in a file with the following naming conventions: E2864md.vvv where • m is the model with value I, L, or nothing. • d is the D channel protocol for ISDN. Check the 2864I user's manual for applicable values. • vvv is the version number. The first letter is the denomination for the model, with E standing for Elite, S for Supreme and B for an internal card model. To update the firmware in a flash EPROM is called an "upload". You can run any communications program on your computer that supports the X-modem file transfer protocol to upload. With the modem in command state, type in ATUPX and the modem will ask for a confirmation. Answer yes and wait for the modem to respond with the prompt: Start programming, please upload.... Once the prompt appears, invoke the X-modem protocol to upload the file E2864md.vvv to the modem which will update its flash EPROM with the firmware contained in the uploaded file. If the upload is successful, the modem will restart automatically. If the upload fails, the modem may get stuck with its flash EPROM being erased. Turn off the modem, and then press the O/A button while turning on the modem again. Release the button a few seconds after turning on the modem. A kernel program will take control of the modem. The kernel is responsible for the firmware upload and update process and accepts a limited set of AT commands including the ATUPX command. If you accidentally get to the kernel control, turn off the modem and then turn it on again to return the modem to normal operation. The Omni models only provide a D/V button. Press this button while turning on the modem for both hardware reset and kernel execution. If the D/V button is pressed for less than 10 seconds after turning on the modem, the modem will perform a hardware reset and run a self-test; if the D/V button is held for more than 10 seconds after turning on the modem, the modem will execute the kernel program to make a firmware upload possible. 4-4

Firmware Update/Upgrade
The 2864 series modem uses 4Mbit flash EPROM(s). The firmware in flash
EPROM can be updated by uploading a file from the locally connected DTE. There
is no need to open the modem case or use a programming device. The firmware is
distributed in a file with the following naming conventions:
E2864md.vvv
where
•
m
is the model with value I, L, or nothing.
•
d
is the D channel protocol for ISDN. Check the 2864I user's manual for
applicable values.
•
vvv
is the version number.
The first letter is the denomination for the model, with E standing for Elite, S for
Supreme and B for an internal card model.
To update the firmware in a flash EPROM is called an "upload". You can run any
communications program on your computer that supports the X-modem file trans-
fer protocol to upload. With the modem in command state, type in
ATUPX
and the
modem will ask for a confirmation. Answer
yes
and wait for the modem to respond
with the prompt:
Start programming, please upload
....
Once the prompt appears, invoke the X-modem protocol to upload the file
E2864md.vvv
to the modem which will update its flash EPROM with the
firmware contained in the uploaded file. If the upload is successful, the modem will
restart automatically.
If the upload fails, the modem may get stuck with its flash EPROM being erased.
Turn off the modem, and then press the
O/A
button while turning on the modem
again. Release the button a few seconds after turning on the modem. A kernel pro-
gram will take control of the modem. The kernel is responsible for the firmware up-
load and update process and accepts a limited set of AT commands including the
ATUPX
command. If you accidentally get to the kernel control, turn off the modem
and then turn it on again to return the modem to normal operation.
The Omni models only provide a
D/V
button. Press this button while turning on the
modem for both hardware reset and kernel execution. If the
D/V
button is pressed
for less than 10 seconds after turning on the modem, the modem will perform a
hardware reset and run a self-test; if the
D/V
button is held for more than 10 seconds
after turning on the modem, the modem will execute the kernel program to make a
firmware upload possible.
