The modem has the following user interfaces:
•
A built-in local user interface provided via the modem front panel.
•
A built-in remote web user interface that provides web pages from the modem (using
a web server) to a web browser.
There are also serial and Ethernet remote control interfaces that allows the built-in
interfaces to be replaced or supplemented by an alternative means of modem control.
These use a proprietary command protocol called the Paradise Universal Protocol (PUP).
This can be used either directly over a serial RS232 or RS485 interface (e.g. via a
HyperTerminal session) or via Ethernet (e.g. via a Telnet session). The Simple Network
Management Protocol (SNMP) v1 and v2c are also supported.
7.1 User Names, Passwords and Modem Control
The modem can be controlled by either a local user via the local front panel, or a remote
web user. In addition, a remote user can either have full control over the modem or be
restricted to viewing modem information. Access to the modem is controlled by
passwords. These concepts are explained in the following sections.
7.1.1
Local Mode
On shipping from the factory, the modem defaults to Local mode, which allows control of
the modem from the front panel interface only. Web users can, however, log in and view
the modem settings while the modem is in Local mode.
Note that SNMP is disabled by default and therefore cannot be used as an alternative
method of remote control until it is enabled. When SNMP is enabled, then SNMP
commands are always obeyed regardless of any user arbitration that is active within the
modem – this point should be taken into account when adding new control facilities to
those already built into the modem.
7.1.2
Giveaway Mode
When the modem is switched to Giveaway mode, a remote web user may assume control
of the modem.
For remote web browsing, there are two fixed user names, namely, admin and user. The
admin user can view and change the modem configuration, while user can only view the
modem settings. Only admin can change the two passwords associated with these two
user names.
Only one remote admin user can be logged in to the modem at any time but multiple
users can be logged in as user at the same time. With remote control users, there is
always an explicit login process, requiring both a valid user name and password to be
entered. Note that remote admin users cannot log in while the modem is in Local mode.
