ADTRAN 1202076L1#DC, 1202076L2 Unit ID, Change/Set a Passcode, Automatic Time-out Feature

Chapter 6. Utility Menu

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 re- quires 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.

Automatic Time-out Feature

For added security protection, the unit is equipped with an automatic time-out for operation with the password. After ten minutes of inactiv- ity, the unit reverts to limited access operation. To make changes in the configuration, the passcode can be reentered. See Set Passcode on page 6-2 for further information concerning passcode use, and both limited and editing access.

If the passcode number is lost, contact ADTRAN Customer Service for assistance.

No Passcode Desired

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.

Unit ID

This menu is used to access the current Unit ID setting. Viewing is avail- able 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. If an out-of-range number is entered, the unit assumes the upper limit number of 999.
