Set User Passcode
The TSU 120 is designed to operate with or without
the use of a passcode.
The passcode should be a number easily remembered. Once
entered, the passcode is required to access any operation
other than viewing.
To Establish a Passcode
Select Set Passcode (item 3) under the UTIL menu. At
the New Passcode prompt, use numbers from the front
panel of the keyboard to enter a unique number up to
four digits.
After pressing Enter a verification prompt is dis-
played. Respond to the verification prompt by
repeating the same passcode number.
If the two entries match, the unit accepts the passcode.
If they do not match, the unit returns to the new
passcode entry field for another attempt.
If the unit is to be remotely accessed using T-Watch, a
passcode must be entered. When managing a number of
units, the passcode can be the same for all.
Special Feature
For added security protection the unit is equipped
with an automatic time out for operation with the
passcode. After ten minutes of inactivity, the unit
reverts to limited access operation. To make changes
in the configuration, the passcode must be reentered.
See the section Passcode in the Operation chapter for
further information concerning passcode use, and
both limited and editing access.
If the passcode number is lost, contact ADTRAN Customer
Service for assistance.
