Abstract
A locking arrangement is provided for limiting access to certain selected menu functions on a telephone terminal is provided. Although these functions are generally located in different sections of the menu hierarchy, each may be unlocked and relocked while a user remains in the same section of the menu hierarchy containing the selected function. For accessing the function, the user enter a password while located in the same section of the menu hierarchy as the function to be accessed. Once the password is entered, direct access to the selected menu function is permitted. The locking arrangement provides for the relocking of each of the selected functions automatically by the user simply exiting the accessed selected function.
