Notes:
 The looped-back Ethernet packets egress the modems from the same port
they were sent to and have the same source and destination addresses they
were sent with. While Ethernet testing equipment can handle this situation it
might be very confusing for normal Ethernet ports or Ethernet bridges.
 The Watson Ethernet tabletop modems operated as DSL slave can only
control LOOP1.
3.8 Password protection
The Watson Ethernet modems feature password protection to management
functions to prevent unauthorized access e.g. on a modem that is installed at a
customer site but is owned and managed by the service provider.
Password protection is global i.e. once the correct password is entered access to
all commands is granted.
By default password protection is disabled. To enable it use the SET PASSWORD
command to define a password and then use the LOGOFF command to lock
access to the Monitor. Now Monitor access must be enabled by entering the
password before any Monitor commands can be entered.
Once the password is entered all Monitor commands are available. The pass-
word has to be re-entered
 after each LOGOFF
 after 5 minutes of inactivity
 after a restart of the modem
Passwords can be changed with the CHANGE PASSWORD command. To disable
password protection use the CLEAR PASSWORD command.
Password protection is only applied to access from the local RS-232 interface.
Monitor access through the DSL EOC is never protected by the password. If a
password has been lost then it can be reset through the DSL EOC with the
CLEAR PASSWORD and SET PASSWORD commands.
Of course this is only possible if the modem who's password has been lost is
configured as DSL slave. If it is configured as DSL master then no remote
access through the DSL EOC is possible. In this situation the modem can be
configured as DSL slave with the DSLSLAVE command which can be entered at
the prompt for the password. After DSLSLAVE the modem will be reconfigured as
DSL slave and the password can be reset from the DSL master as described
above.
