11.2 Load and Backup

This section demonstrates “Load” and “Backup” transaction via a web management interface. Let us start with

discussion of a few terminologies:

Program refers to the file which contains binary instruction sets that controls the CPE

system.

Data refers to the file which contains network and user specific configuration

Load refers to transferring of system program file or configuration data file from an

external host into a CPE.

Backup means saving of configuration data file from a CPE to an external host.

TFTP and HTTP protocols are supported to Load and Backup new firmware and/or system configuration files.

Configuration data can be backed up from CPE to an external host, or restored from external computer into a

CPE IAD. The external host must have IP connectivity with the CPE device.

11.2.1 Load or Backup over HTTP

Similarly, the system firmware and configuration files can be loaded into the CPE via HTTP protocol. The

configuration files can be backed from the CPE to the external host. The external host in this case is the

computer which runs the web browser to access the network management pages.

Information The external host in this case serves as a HTTP client. The CPE serves as a

HTTP server.

11.2.1.1 Load System Files to an CPE from a Web Browser

1. Obtain the latest version of system firmware. (e.g. iad.prg.)
