Security
Modem 3600 8-9
Level 1 security does not require a callback number; however, if the
security level is changed to level 2 or 3 a callback number will be
required.
The callback number should be programmed initially using the $Cn=m
command. Where n is the user number and m is the callback number.
Extended Features $W

A regular user can change his password and callback number if the local
superuser has enabled the $W1 option.

A remote regular user can gain superuser privilege once the local
superuser has enabled the $W2 command.

The extended feature options can be cleared by a local superuser by

Display Extended Feature Status $W?
Enter the $W? command to display the status of the user changes and
remote superuser options.
Display / Reset Illegal Access Attempt Counters $M,
$Mn, $M*
These commands inform the superuser of any illegal attempts to gain
superuser status and the users current status. The status will either be
"normal," indicating the user is still able to logon to the secure Modem
3600, or "suspended," indicating that the user made more than seven
illegal attempts to gain superuser status and has been automatically
suspended.
When the superuser logs on, the secure Modem 3600 automatically
displays any illegal attempts since the last superuser logon. If it is not
reset, the illegal attempt count will remain and the superuser will not be
reminded unless more illegal attempts occur. To manually request this
same information enter
