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)CNTRL PORT, 1)DATA RATE to permit changing the
data rate.
Change/ Set a Passcode
The passcode can b e changed or set at any time or el iminated alto-
gether through the Utility menu item 3)SET PASSCODE. This pro-
cedure requires the current passcode (if one is established) for
operation.
The passcode can only be entered by using numbers. After enter-
ing the desired passcode, press Enter.
Set a null passcode at the 3)SET PASSCODE menu by pressing
Enter without any nu mbers. This set s a null passcode and grants
unlimited access.
Special Feature
For added security protection the unit is equipped with an auto-
matic time-out for op eration with the pa ssword. After ten m inutes
of inactivity, the unit reverts to limited access operation. To make
changes in the configuration, the passcode can be reentered. If the
passcode number is lost, contact ADTRAN Customer Service for
assistance.
No Passcode D esired
At the New Passcode 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 Unit ID
prompt.
