Pressing any key after entering a passcode causes the unit to
return to the previous active menu. In this case it returns to
2) CONFIG , 2) UNIT , 1) CTL PORT RATE , to permit changing the data
rate.
Change/Set a Passcode
The passcode can be changed or set at any time or eliminated
altogether through the Utility Menu item
3) SET PASSCODE
. This
procedure requires the current passcode (if one is established)
for operation.
The passcode can only be entered by using numbers. After
entering the desired passcode, press
Enter .
Set a null passcode at the 3) SET PASSCODE menu by pressing
Enter without any numbers. This sets a null passcode and
grants unlimited access.
Passcode Automatic Time-out
For added security protection the unit is equipped with an
automatic time-out for operation with the password. After ten
minutes of inactivity, the unit reverts to limited access opera-
tion. To make changes in the configuration, the passcode can be
reentered.
If the passcode number is lost, contact ADTRAN Customer Ser-
vice for assistance.
No Passcode Desired
At the N EW P ASSCODE prompt (in the Set Passcode menu), press
Enter without any numerical entry. The system nullifies the
need to enter a password for subsequent use and proceeds to
the
U NIT ID prompt.
Unit ID
This menu is used to access the current Unit ID setting. View-
ing is available in limited-access mode. Editing or changing the
Unit ID requires the use of a password, as in editing mode. Unit
identification numbers must be between
2 and 999 .
