C

Image File

Read-only parameter. The name must match the name

 

 

Name

of a file on the TFTP server for an image file download

 

 

 

to occur.

 

 

 

 

 

 

D

Image Load

Specifies how the Ethernet bridge code is loaded. The

 

 

Mode

Megabit Modem CRA-C supports both local and remote

 

 

 

loading. Local image code is contained in flash devices

 

 

 

for local loading of operation code. When loading over

 

 

 

the network, use BOOTP (RFC 951) TFTP (RFC 783) to

 

 

 

obtain image files.

 

 

 

Set Local (default) to load the image file from the

 

 

 

application sector of the Megabit Modem CRA-C

 

 

 

non-volatile device, if valid. The code is valid if the

 

 

 

CRC calculated on power-up matches the expected

 

 

 

CRC. If it does not, the Megabit Modem CRA-C

 

 

 

attempts to get a new image via the TFTP.

 

 

 

Set Network (with local backup) to attempt to download

 

 

 

the image file over the network. It first issues a BOOTP

 

 

 

request to get the image filename and image server IP

 

 

 

address, then it initiates a TFTP session. If the BOOTP

 

 

 

fails, the TFTP fails, or the downloaded image is

 

 

 

invalid, the image file is loaded using the local image

 

 

 

mode.

 

 

 

If no image is loaded after cycling through the TFTP

 

 

 

process at least five times, the Megabit Modem CRA-C

 

 

 

resets and repeats the process.

 

 

 

 

 

 

E

Packet

Indicates the encapsulation format used to envelope the

 

 

Encapsulation

Ethernet packets over ADSL. Choices are HDLC

 

 

 

(default) and PPP.
