Security Database Lock Option
From the Security Menu you may elect to LOCK the security database with the
‘ L ’ option.
When locked, the user cannot change the #E setting or clear the security database even with the
&F. command or power-on reset with the Mode Switch depressed.
The only way to alter the database or #E selection is to enter the Security Menu with the
security password and unlock the database with the
‘ F ’ (Free) command.
The current state: LOCKED or FREE is displayed below the Security Menu.
+
Shorting out the NOVRAM battery will erase the database but will result in the
modem being only partially functional. Such modems need to be returned to the
factory for re-configuration.
Outdial Disable Option
If modems are to be used only for receiving calls option
‘ K ’ can be selected.
This does not allow the modem to dial out. If an attempt to do so, users will be informed that a
SECURITY LOCKOUT is in place and the call will not be successful.
The outdial feature will be useful for system administrators who wish to control the use of
modems within remote offices or restrict modems to being used for receiving calls only.
